I'd love to see something like this, but I would hope it would not be LIMITED to 2400 bps. Also, I'd hope that any such product would support the ability to put a document on hold so that someone could call in and pick it up at their expense. Anyone contemplating doing something like this should try to get hold of a program used in Fidonet called BinkleyTerm (chances are that a Fidonet node in your area has it). As far as I'm concerned, this program is the current state of the art for intersystem transfer of messages and files. Of course, it uses Fidonet node addressing and file naming conventions, but the principles would be the same. The reason I recommend looking at this program is because 'C' source code is available from many BBS's. BinkleyTerm allows you to send mail bidirectionally (sending and receiving simultaneously), it allows for recovery of an interrupted session (it will save the part of a file already received, so that on a later call only the remaining portion needs to be transmitted, not the entire file), and it can send mail on fairly complex schedules if necessary. Of course you probably don't have anything that complex in mind, but I would hope that it would at least be possible to enter a message and then have the unit delay transmission until late night when the rates are low. But ... I also think that the first person who makes a LOW COST, easy to use mail package will get a big jump on the market. Right now electronic mail is just too complex for the average user, but at the same time, I can see where paper mail is getting less and less reliable, and as you've noted, FAX transmissions are definitely inefficient. Let me propose a hardware/software combination that might work real well: 1) Coded ring capable ... will answer the line only if a certain ring pattern is received, if desired. 2) Has sufficient memory to store (reasonable amounts of) both incoming and outgoing messages when the associated computer is off. Has provision to alert user (by audible signal or some other means) if memory limits are about to be exceeded, so user can turn computer on and download some data from the hardware unit. 3) Can easily be restricted to send mail only during low rate periods. Preferably this should be programmable, especially for those who call overseas, since the "low rate period" varies from country to country (and carrier to carrier in the U.S.!). Also would be nice if you could program in number-specific dialing prefixes/suffixes (to select carriers, or get through voicemail "front ends"). 4) Uses SIMPLE addressing -- phone number only where possible! 5) Will detect various call progress tones and NOT keep trying numbers that answer without giving any useful response (such as voice answers!). 6) If a transmission is interrupted, will save the part received (if you're the receiver) and on next connect, only require transmission of the remaining part. 7) Will COMPRESS data to the maximum possible before transmitting. This should be done offline, BEFORE the call is made, so that more efficient algorithms can be used. Compression should be at least as good as that achieved by the MS-DOS programs LHARC or ARJ. You may also want to think about an upgrade path in case better compression algorithms are developed later. 8) Should be able to send and receive data simultaneously using a bidirectional protocol (like the JANUS protocol used by BinkleyTerm). 9) If it calls a system and there is mail on hold for the caller, it will pick it up, BUT the caller should be able to PARTIALLY disable this on an individual number basis. What I mean is this. Let's say you (system A) call another system (system B) to deliver a three page letter. He has a two page letter on hold for you. Since his letter is shorter and since the bidirectional protocol is capable of sending and receiving simultaneously, your system would ALWAYS pick up that letter since to do so would not add to your costs. However, let's say that you're sending a one page letter and he's got a 100 page document on hold for you. You should be able to refuse to pick that up, or to maybe pick up just the first page and then wait for him to call you to get the rest. This all sounds complex but most of it would be hidden from the user. In practice, the user would type up the message, tell the system the destination phone number, and the message would automagically be sent at the proper time. That's the sort of system I'd like to see, anyway!

Sure, that's inherent in the UUCP scheme. [discussion of Binkleyterm] Maybe.

Good one. > 6) If a transmission is interrupted, will save the part received (if you're > the receiver) and on next connect, only require transmission of the > remaining part. Probably not a big deal, since most messages are going to be small enough that call set-up time dominates. Plus, the existing protocols don't support this, and we need to make it compatible with commercial services (if it uses UUCP, it will hook directly to AT&T mail, UUPSI, etc ...). > 7) Will COMPRESS data to the maximum possible before transmitting.

Would be nice, but the existing protocols don't support that. I'm not sure how important this is... if you have that much mail traffic to a single person, you probably want to be using a commercial mail relay anyway. > 9) If it calls a system and there is mail on hold for the caller, it will > pick it up, BUT the caller should be able to PARTIALLY disable this on an > individual number basis. This is inherent in UUCP call grades, though not all UUCP versions support call grades.

Is it price competitive with a FAX machine when you factor in the cost of the computer? Is it compatible with existing Email systems without an AT&T Mail account to help (assuming the answer to the first question is YES)? Are the protocols published so I can build a standalone Email box, or implement it for a computer AT&T doesn't support? If the answer to any of these is "no", it's not the answer.

John should have no problem at all, nor would anyone else except in the immediate area of the quakes, which were very far away from most of us. As is often the case, the media haven't been very careful about saying exactly where the quakes were! They were up in Humboldt county, close to the Oregon border, a couple hundred miles north of any major population centers (which hardly noticed a thing -- see below). The small town of Petrolia was closest (though not hardest hit) to the epicenter, which was about 5 miles below the surface and about 35 miles south of Eureka, CA. This area, known as the "Mendicino Triple Junction", is where three crustal plates rub, and where the northern end of the San Andreas Fault intersects the Mendicino Transform Fault (which runs west into the Pacific Ocean). Several hundred earthquakes a year occur there, "the most seismically active place in the lower 48 states" (per Monday's {San Jose Mercury News}). The initial main quake (6.9) was Saturday around 11:00 am. First major (6.0) aftershock was 00:42 Sunday, with another major (6.5) one at 04:18 Sunday. Oddly enough, neither of the first two was felt in the Bay Area, while the third woke people up all over the Bay Area -- and as far east as Reno and as far south as Carmel! This is probably because the latter one was quite long, some 10 - 15 seconds by various reports. (Yes, I happened to be up, and heard the house rattling gently but definitely for about that length of time. Does a long rolling shaker propagate further than a short, sharp bump?) As of Monday afternoon, there had been over 5000 recorded aftershocks, though none anywhere near as strong as the two major ones. Damage from the primary quake was bad enough, but the smaller 00:42 Sunday shock started a fire in downtown Scotia which completely wiped out the tiny business district: a market, a lumber/hardware store, a pharmacy, and a coffee store. Here is a list of the most seriously affected towns and their losses: - Ferndale (pop. 1,367): 30 homes, 40 businesses, $4 million damage - Petrolia (pop. 1,500): 10 homes, one business, $1.5 million damage - Rio Dell (pop. 2,687): 20 homes, 20 businesses, $7 million damage - Scotia (pop. 950): 4 businesses, $15 million damage Area hospitals treated 94 people, admitting 12. There were no reported deaths. In the immediate affected area, about a 30 mile radius from the epicenter, power outages were widespread. Water lines were cut, and some areas had to be served by trucked-in supplies, including water to fight the Scotia fire. Telehone service was reported as "unreliable", though KCBS reporters seemed to have little or no difficulty calling in their reports (they mostly use cellular phones). In fact, because of the number of "live reports" on Bay Area radio stations, I'm guessing that the "unreliability" of the phone service was probably due mostly to jamming of the lines by friends and relatives trying to call in, rather than to actual damage.

The one from 'dquist' arrived first, but I received many copies throughout the day Tuesday and Wednesday. PAT] AT&T ANNOUNCES *** AT&T today announced a new service for people on the move. AT&T EasyReach 700 Service will offer consumers nationwide, for the first time, a portable long-distance number that is theirs for life and a package of features that will let them choose which calls follow them and who pays for the calls. For $7 a month, consumers will receive a 700 number that remains theirs as long as they remain EasyReach 700 subscribers -- no matter where on the U.S. mainland they may travel or move. The average American now moves 11 times in a lifetime. EasyReach 700 Service will also give subscribers the advantage of selective call forwarding that can be programmed from any touch-tone phone and the option to receive calls that are toll-free to the caller just like those to 800 numbers. The service differs from standard call forwarding offers in that subscribers will choose which calls follow them. Subscribers can even choose to have only some EasyReach 700 calls follow them by assigning four-digit Personal Identification Numbers (PINs) to certain callers and then instructing the service to forward only those calls. Those calls made with a PIN are paid for by the subscriber. Charges for those calls will be sorted by PIN on the monthly bill for easy tracking. The service is designed primarily for long-distance calling and subscribers are expected to retain a local telephone number. EasyReach 700 calls will be billed at fixed per-minute prices, regardless of distance. State-to-state rates will be 25 cents per minute from 8 a.m. to 5 p.m., Monday through Friday, and 15 cents per minute at all other times. Prices for in-state calls will vary by state. ------------------------------ From: barry@coyote.datalog.com (Barry Mishkind) Subject: 700 Numbers Start in June Organization: Datalog Consulting, Tucson, AZ Date: Wed, 29 Apr 92 17:38:03 GMT Overheard on CNN this morning: "AT&T will provide a permanent nationwide 700 number for those that wish, starting in June.

LEWANDOWSKI, 786-3512" Subject: AT&T 700 Easy Reach Service In the 29 April issue of the {Wall Street Journal} (page B1), it is announced that AT&T will introduce a number of ten digits with a area code of 700. For only $7.00 a month one can own a number that will follow you around the United States, and it allows you to decide which calls you want to receive. It can also act like a 800 number when callers add a four digit access code after the number. The charge to the subscriber is 25 cents a minute during peak hours and 15 cents a minute during off-peak hours. It seems to me that this service is a lot more customer-friendly than MCI's "Follow Me" service, but I still want to see the finer points before making a real judgment about this service. Does anyone have any additional information, or an AT&T number that I can call to find out more? Thanks, John C Lewandowski LEWANDOWSK_J@CUBLDR.COLORADO.EDU ------------------------------ Date: Wed, 29 Apr 1992 23:23:43 -0400 From: Monty Solomon Subject: AT&T EasyReach 700 Service From the 4/29/92 {Boston Globe}: AT&T yesterday introduced permanent, portable long distance telephone numbers for people who want to be reached easily as they travel. Called EasyReach 700, the new offer will allow customers to use a single telephone number no matter where they are within the Lower 48 states. The service differs from standard call forwarding in that subscribers may choose which calls will follow them. AT&T said it expects the service would appeal to busy individuals who do not want to miss calls as they go from office to hotel or from car phone to weekend getaway. ----- Excerpt from the 4/29/92 {Wall Street Journal}: For telephone customers who want to be reached anywhere, anytime, AT&T says it has your number and will assign it to your for life. AT&T yesterday said it will begin selling by mid-June a new phone service in which subscribers are assigned a new ten-digit phone number, including a 700 prefix that can follow you for life -- and for a fee, of course. Called EasyReach 700 Service, the plan allows a customer to call a central AT&T number and using a touch-tone phone, tell a computer to route calls to another number. Friends, family, or business associates wouldn't have to worry about learning each of your phone numbers; they'd need only to know your 700 number. The fee: $7 a month, AT&T said. The number an AT&T customer gives to outsiders will be constant as long as the customer remains with AT&T. Subscribers can choose which calls they want to receive. And they have the option of receiving calls that are toll-free to the caller. All the caller has to do is remember to punch in a four-digit PIN assigned by the service subscriber after dialing the 700 number. This way the call is automatically billed to the called party. The charge to the subscriber is $0.25/min peak (M-F 8-5) and $0.15/min off-peak. The new service is limited to the mainland U.S. for now. In addition, customers must make the call over an AT&T line or dial an extra five-digit access code to sent the call over the AT&T network. AT&T Bell Labs figured that there are about six million possible combinations of ten-digit numbers that can be offered using the 700 prefix. AT&T may marry the new service with some of its new credit-card and calling-card programs so that your number covers all your transactions in the future. -------- I spoke with an AT&T representative today and got some information: The service is not yet available. It is scheduled to come before the FCC on 6/2/92. They will send me a postcard when it is available. You can request a specific number and pay a one time charge of $25.00. There is a $10.00 setup fee which will probably be waived for the first few months. The call routing can be changed from any touch-tone phone. There will be a credit card option with an $0.80/call surcharge. There will also be third-party billing available with a 4-digit PIN. To change routing, the EasyReach subscriber dials 0-700, then their personal number, then a four-digit PIN, then 1-#, and the number to which calls are to be routed to. The subscriber can assign up to 20 four-digit PINs for reverse billing. The $7 monthly fee includes call-waiting. Excerpt from the 4/29/92 {New York Times}: Call-forwarding has been available in some form since the late 1960's, but is second in popularity to call-waiting, which signals when someone is trying to call when the line is in use. Nationally, about 30 percent of eligible telephone customers use call waiting, while about five percent use call-forwarding, according to Bellcore. In New York state, fewer than 500,000 customers subscribe to call-forwarding. That compares with two million for call-waiting out of 6.5 million eligible residential customers, according to Nynex. Part of the reason for call-forwarding's slow growth may be that the subscriber has to remember to establish and disconnect call-forwarding for each phone. The doing and undoing of the service could be annoying to customers. The current call-forwarding transaction is actually two calls, although the dialer may not realize it.

I somehow neglected to pay my current phone bill and when I remembered, couldn't find it. So I decided to wait till the next month and pay at the same time. Well the next bill arrived and I put it aside to pay. I then went away for a few days holiday and forgot about it! Well a couple of days ago I found my phone had been disconnected (actually sounded like it was faulty till I called the fault service and was told it was disconnected for non-payment). They said they (or their computer) had called me nine times to tell me if I did not pay the phone would be disconnected. I was away on the day they called and there were messages on the machine. Finally in annoyance I got hold of a supervisor. It turns out the computer messager they have is not compatible with answering machines -- it calls your number and as soon as you or your machine answers it spits out its spiel. If you have an answering machine the delivery is usually over before your outgoing message is complete. Hence no record of the call. I was told they were aware of the problem and were making changes to the program to handle this (I wonder how - listen for the beep -- wait for 30 seconds after answering [this would be confusing if you actually answered the phone]). I guess the real answer is to pay on time and wait for competition in local phone service -- we already have competition in LD which has improved service a great deal. As an aside after I paid the phone was reconnected within an hour. I had a very restful evening that night!

You feel imposed upon that they took such an action, and intend to give your business to a competitor if one ever comes along. As is quite common with debtors, you turned things around to become the injured party and demanded to speak with a supervisor. Instead of speaking with a supervisor, you should have been instructed to stand in line and wait your turn at the cashier's window. You note that since there is competition in LD it has improved, and your implication seems to be that if a competitor for local service comes on the scene things will improve locally also. How? Will the new company let you go six months and a dozen phone calls without paying your bills? You gloss over in one sentence the fact that upon payment your service was restored almost immediatly, ignoring the fact telco could have left you cut for a couple more days while they cleared your check at the bank; required a deposit to assure prompt payment in the future and otherwise diddled around with paperwork.

Neither AT&T nor other IXCs are PROHIBITED from carrying intra- LATA traffic by the FCC or the Judge; remaining prohibitions from these areas deal mostly with rates, accounting and such. In VERY general terms, the IXC market is viewed as mostly-competitive and has relatively few anti-competitive restrictions (though AT&T still has more restrictions than others). On the other hand, the LEC markets are viewed as non-competitive, and thus the major LECs are prohibited from carrying most inter-LATA traffic. Existing intra-LATA traffic restrictions are typically imposed by the STATE Utility Boards (e.g., PUC). The original rationale was that the higher-than-necessary intra-LATA toll rates were used to help hold down prices of residential POTS service, just as higher "long distance" rates did before 1984. Some PUCs already allow intra-LATA toll call "competition" by requiring the LECs to permit 10XXX access for intra-LATA calls. But they only allow this after the LEC has modified its rates and/or changed accounting practices to segregate toll costs/revenues from services previously supported by such toll calls. In most areas, this would have the effect of raising monthly rates and reducing toll rates, perhaps with some other changes such as "free" calling areas. (Maybe these should be call "prepaid" calling areas?) > The other big question is, of course, is: Is it actually cheaper to go > through an IXC than through the local telco? This requires an understanding of the LEC rates, IXC rates, your calling patterns and any "plans" that offer discounts based on call volume. Only you can answer the question. Don't expect the answer to remain valid for any long period of time. Note that letting the customer make this decision avoids lots of messy problems, like deciding what constitutes a "toll" call. In an area with Message Unit billing, a call that's billed in Units might cost more or less than an IXC depending on the call duration, initial period, discount plans and time-of-day. Aside from the duration issue (can you predict call duration?), the decision of what's the cheapest access method is still so complex that PBX/Centrex customers pay for Automatic Route Selection (ARS) features to make the choice.

Intra-LATA traffic is controlled by your state's Public Utility overseer (PUC in NH, which is only one LATA, so I can't speak for multi-LATA states). If your PUC has never ruled on intra-LATA competition, IXC'x may try to provide the service "off-tariff" by running the traffic out of the state and back in, thereby calling it interstate traffic. Both the FCC and PUC are likely to frown on this, and I recall vaguely some kind of lawsuit in NYC on this very issue, involving Off Track Betting, which had lines to New Jersey in order to avoid intra-LATA (or intra-state) charges. His other question was, is it cheaper? Since in NH the major profit maker was pulled out from under the BOC, New England Tel has pretty high intra-state rates -- 26 cents per minute, with time of day discounts and volume discounts that may get you as low as 11 cents per minute. Most IXC's will offer band one at high volumes at 10 cents a minute or less. kath mullholand university of new hampshire durham, nh ------------------------------ Date: Tue, 28 Apr 92 13:58 PDT From: john@zygot.ati.com (John Higdon) Reply-To: John Higdon Organization: Green Hills and Cows Subject: Re: IXC's Carrying Intra-LATA? Not every state was as short-sighted as California in setting up a monopoly for the LEC to carry intraLATA calls. In many areas around the country, any carrier can handle intraLATA traffic if the customer so desires. Whether you will save money is something you will have to research for yourself. California's intraLATA rates are unquestionably the highest in the country because the PUC, in its infinite wisdom, gave Pacific Bell a license to gouge virtually any amount it so chooses for calls to neighboring towns. In other places, it is probably a six of one, half dozen of the other just as interLATA rates are amoung the major carriers. > I'm assuming they meant 10333.

If you can't route intraLATA calls to an IXC then it is because the LEC blocked access. I guess its possable some of the smaller IXC might have a problem with it, but Sprint/AT&T/MCI will be happy to carry them. If FGD access to IXC's is blocked, sometimes you can still save with FGB access. If not, and you're big enough you get a T1 (or Primary Rate Interface ISDN trunk) to the IXC POP. > Is this legal/legit, or did someone misprogram the CO's switch, or > what? It may well be illegal for them to market the service, but you welcome to use it, the main problem being blocking of FGD intraLATA calls > The other big question is, of course, is: Is it actually cheaper to go > through an IXC than through the local telco? I can call any other LATA in the state of Alabama for the price of a ten mile intraLATA call. Calls to nearby states are even cheaper of course. Give it a try. IntraLATA traffic is the golden cow of the LEC, or was that the inside wiring maintainance plan, or DTMF service, or DID, or B carrier cellular, or ... Yes I'm down on SCB, #1 I graduate in June and their not hiring, and #2 they may offer ISDN in the Auburn area soon ... for ESSEX (Centrex) custimers only (minimum eight lines until the new tariff comes out, then it will be three lines). But they will deliver as little as one B channel to a premise. Real Useful. Has anyone done inband signaling on ISDN :-) In their defense they are 100% SPC CO's, have lots of fiber, SS7 connections to the IXC's are soon to come, BISDN is being field tested in NC, etc. Pat Turner KB4GRZ pturner@eng.auburn.edu ------------------------------ From: andys@ulysses.att.com (Andy Sherman) Subject: Re: Jeff's Phone Company of Rahway, NJ Date: Mon, 27 Apr 92 01:22:17 EDT On 25 Apr 92 22:16:14 GMT, krfiny!jeffj@uunet.uu.net said: > (2) This could be justified if there were enough calls within > the service area, no?

Leaving aside the rest of your article, some of which was intriguing but much of which was, self-admittedly, dreaming, let me ask, where did you get such a bizarre idea as this one? I believe that customer calling patterns come under the heading of Customer Proprietary Network Information (CPNI) which is not to be divulged to third parties by an interexchange carrier. Sitting at AT&T, I would have to say that MCI and Sprint are third parties to us, as we must be to them. Such sharing of information as you describe is against FCC regulations. It would also be skating on real thin anti-trust ice, too, since some might take it as evidence of cartel-like behavior. It would also be real stupid for any of the big interexchange carriers to give away marketing information like that to the competition. As for your proposal, the information for calling patterns withing Rahway could only come from the LEC, if they even collect it.

I seem to remember them doing the same thing about five years ago too. It looks like they do this every few years, the crackdown lasts about a year and then they get lax again. Back in high school days we used to occasionally third party bill calls to a local branch of one of the big banks outside banking hours, if the operator questioned the call at all we claimed to be a bank employee in town on business and "they told me to bill my calls to this number", we were never turned down. In all likelyhood the person who made the calls is someone you know casually who just picked your number for a while. If it was organized phreakers they would have hit you for a lot more. > ABTW, I think that I can win the prize for having the lowest average > monthly long distance charges of any regular telecom reader - anyone > have anything lower than $3? :-) The AT&T operator even asked me if > that was my normal amount of long distance usage.

I also probably would place high in the least features added to a line contest at a grand total of one, touch-tone. When Bell switched our excahnge to a DMS last fall they gave us eight weeks of free call-waiting, in two months it went off exactly once so I figure, why bother.

I called to have the charge removed and asked how it could have been billed to me. They said the billing and connecting were done separately, so maybe the operator merely mistyped the billing number. I was a little surprised. They offered to disallow third-party billing in the future, but I didn't take it. I asked if they had a service that would disallow having numbers _incorrectly_ (w/o authorization) billed to my number but, alas, they did not offer that service and, from what I could tell, had no plans to to so.

The final goal for the working group is to produce standards for the TCP/IP protocol suite and recommendations which could be used by other internetworking protocol standards (e.g. ISO CLNP and IEEE 802.2 Bridging). The working group will initially develop experimental protocols for encapsulation, multicasting, addressing, address resolution, call set up, and network management to allow the operation of internetwork protocols over an ATM network. The working group may later submit these protocols for standardization. The working group will not develop physical layer standards for ATM. These are well covered in other standard groups and do not need to be addressed in this group. The working group will develop models of ATM internetworking architectures. This will be used to guide the develop of specific IP over ATM protocols. The working group will also develop and maintain a list of technical unknowns that relate to internetworking over ATM. These will be used to direct future work of the working group or be submitted to other standard or research groups as appropriate. The working group will coordinate its work with other relevant standards bodies (e.g. ANSI T1S1.5) to insure that it does not duplicate their work and that its work meshes well with other activities in this area. The working group will select among ATM protocol options (e.g. selection of an adaptation layer protocol) and make recommendations to the ATM standards bodies regarding the requirements for internetworking over ATM where the current ATM standards do not meet the needs of internetworking.

Pat, this subject has been beaten to death over and over again. On the other hand, "you started it." :-) Let's suppose that there are maybe 1000 phreaks in this country who have the technical know-how to bypass the telcos' billing systems and make free calls. Let's further imagine that all 1000 of them piled onto the system at once. Since most of 'em are students or people who work for a living, to get 'em all on at once you'll have to move it to off-peak time. Do you really think that at off-peak times that any part of the telephone network is under enough load that it can't handle another 1000 calls? That's why they have off-peak pricing! So even in the worst case scenario, the phreaks aren't adding anything to the telcos' costs; they have to provide that equipment to cover peak demand periods. You of course bring up the matter of tariff ... though surely you realize the futility of bringing up US telcos' tariff language with someone whose net address ends in ".nl". That's the POINT he's making; that his country's phone-related legislation recognizes that the cost to track down and harass the phreaks is more than it's worth, since all they're doing is uses resources that nobody else needed right then anyway. Littering is illegal. Shall we hire as many cops as it takes to catch every litterer, and fine them enough to pay the costs? It would have a salutary effect on littering, but it's much cheaper in both legal costs and social costs to just pay people to clean the streets and use social pressure and pride to reduce littering. Why wouldn't this work with phreaking? Don't forget those social costs. Remember, the guys who started Apple Computers are widely reported to have built their expertise (and possibly raised some of their startup capital) by blatant phreaking, the sale of blue boxes. Would America, or the world for that matter, be better off if these guys had been caught, tried, and blacklisted from ever working with computers? J.

Added usage of bandwidth causes the telephone company to have to add bandwidth, and guess who pays? All of the other customers who actually PAY our bills end up paying for the hacker, so they are actually stealing from *ME*! Pat's shoplifter example is right on the money. In the same way, other customers end up paying for the shoplifter because the storeowner/teleco raises prices to cover their higher costs. This is similar to the problem many U.S. citizens have with socialized medicine and other social programs -- they don't mind helping pay for someone who cannot afford services, they just resent having to pay for those who just don't *want* to pay for them.

PAT] ------------------------------ Date: Thu, 30 Apr 92 01:02:00 -0700 From: rlm@ms_aspen.hac.com (Robert L. McMillin) Subject: It's a Riot Having won the war (Willie Williams, late of the City of Brotherly Love, is now LAPD Chief-Designate) and lost the battle (a virtually all-white jury uniformly acquitted Rodney King's uniformed attackers), the hotheads are trashing Los Angeles' South Central neighborhood, looting and burning everything in their mindless paths. At last count, no fewer than 31 five-alarm fires were burning in South Central. One firefighter had been shot in the face, but was in stable condition. A roving gang of thugs stopped a truck driver and beat him bloody; he finally escaped and managed, somehow, to get to a hospital, where he is now in critical condition. Firefighters go from one disaster to the next, accompanied by police escort. In some areas, police have yet to respond to 911 calls -- in part because there simply aren't enough cops to go around, and also because they fear the residents. Downtown at Parker Center, LAPD headquarters, a demonstration that started peacefully rapidly descended into violence. Rioters burned and overturned a police car(s?), attempted to overturn a LA Unified School District school bus, and threw rocks and bottles at police in riot gear. On my way to work this evening (a scary thought!), I saw one plume of smoke that looked like it was in Watts, and another much closer to home, possibly in Hawthorne or Inglewood. The governor, Pete Wilson, has called in the National Guard and declared a state of emergency in Los Angeles. (He also went on to say that he would provide all resources needed to put out the riots; in the face of the recent budget cuts that left education in California bleeding badly, one has to wonder about his priorities ... Cal State Long Beach, a campus with about 20,000 to 30,000 students, was this semester able to offer six sections of English 100, a class that is a prerequisite for 29 majors.) The obvious comparisons to the Watts riots in 1965 leave one wondering just how much goodwill the rioters will burn simultaneously. After the 1965 riots, supermarkets disappeared from Watts. Mom-and-pop grocers, their prices inflated by high insurance and distribution costs, have replaced them utterly. Pacific Bell, the only telco in the area of the disaster, has urged all residents in South Central to stay off the phone lines, since the local exchanges are all but completely busy. Robert L.

Dialtones are a little slow here right now, and not surprisingly, long-distance in and out of the city seems a little erratic. Specifically, I got several "your long-distance company cannot complete your call" messages while trying to call to Missouri, and my parents there got a couple different ones ("cannot complete", "phone is disconnected") trying to reach me here. I was finally able to get through using 10222 (ATT is our default).

Suffice it to say, as I write this, LA is under a complete curfew, police and fire have been stretched to the point of non-response, and the business day has been cancelled tomorrow (Friday). Telecom is being severely effected. From here at UCLA I can call off campus, but I can not call into Santa Monica. Someone else here has been able to complete a call to Santa Monica, but only got through once. Calls to the Mar Vista area are also being blocked. Locally the recording says due to "volume" of calls. From San Francisco, (where they are having their own share of problems) calls are being blocked to the same areas with a recording saying something to the effect of "Due to problems with the local phone company ..." (This is not verbatim). As I was sitting here logged on, someone must have fingered me on this machine, as I got an e-mail note from a complete starnger in Sonoma who was desperately trying to get ahold of their spouse in the Culver City area. They asked me to call, and I was able to get through, and relayed the message. I had no trouble being called at UCLA, or calling from UCLA to San Francisco. There have been no problems calling from UCLA east to Beverly Hills, LA, or east of there even. Strange that only some GTE areas on the west side here seem to be effected, when none of the fire bombings are out here (yet). That's the word from this vantage point. I'm sure there's more telecom problems in the effected areas, but I haven't experienced them. A. Jacobson ------------------------------ Date: Thu, 30 Apr 92 23:39:28 PDT From: aimla!ruby!rudholm@uunet.UU.NET (Mark Rudholm) Subject: Riots in L.A. Greetings to all from the city of The Angels! It is shortly after 10 PM on 4/30/92, I'm editing this message from my home in the Hancock Park district of Los Angeles. So far, 24 people are dead, 450 people are injured and there have been 1,300 structural fires. Initially, the fires were contained to South Central L.A. but this morning, the fires saw no geographical boundries. Now, all areas of the Los Angeles area are affected. There has been VERY widespread looting. You can take a stroll down Wilshire Boulevard and pass looters wherever you turn. People are very bold about looting, they are not deterred by the presence of onlookers, news crews, or in some cases, even police. Try to comprehend this, this is not something that has remained confined to a specific area. There has been property damage, fires, and looting in even the wealthiest areas, including Hancock Park, Beverly Hills, West L.A., Brentwood, and Westwood. There have been snipers on rooftops, most notably, one on a building at Melrose and La Brea shooting at anything on the streets below. There is VERY unsettling news footage of looters and vandals behaving as if participating in some demented carnival, laughing, yelling, and waving at news crews. The sky is black, it smells of smoke EVERYWHERE. Almost all businesses are closed, many closed early. There is a curfew in force for all areas within the corporate limits of the city of L.A., almost all nearby cities, and portions of the unincorporated L.A. county area. As far as telecom issues go, (my theory on the cause of this whole thing is that people are protesting the end of the 213/310 area code permissive dialing on Saturday :)) this is what I can tell you ... dialtones are slow in coming, occasionally you get them immediately, occasionally you have to wait over two minutes, usually you have to wait about 5-10 seconds. I'm on an ESS5 and more often than not, when I finish dialing a sequence, I get dropped back to dialtone (or the queue for dialtone as the case may be). Sometimes, I get reorder, sometimes I get an all circuits busy recording from my CO or some other along the way to the terminating end, and sometimes I get through. All this is pretty congruent with high volumes of network traffic as far as I can tell. Pacific Bell, GTE California, and AT&T have all issued the usual request that customers use the phone only when we need to. Problems of this nature also occur immediately after earthquakes. Even the cellular network is being over-taxed. If an open channel is unavailable, my cellphone retransmits the call request repeatedly until the call goes through (I thought this was a pretty useless feature until today!) Even with my Access Overload class of 15, it sometimes takes a couple of minutes and a dozen attempts to get a call placed. Also, the cellular network seems to have been having problems locating me when I get incoming calls. Some of the fires have apparently damaged cable TV facilites. According to my cable company, this is why I have no service at the moment. And now I hear news of similar events taking place in San Francisco and Las Vegas.

From: Stan Hall Reply-To: Stan Hall Date: Thu, 30 Apr 92 14:42:15 CDT Organization: The Obelisk I just thought I would ask the wonderful readers of comp.dcom.telecom for opinions and suggestions about my telephone situation. I am a student at the University of Oklahoma and am living in university owned apartments. The rent for these apartments includes the cost for the phone service. The phone service is provided by the university telecom service. The entire university is set up on a large PBX so all I have to do is dial an extension for campus phones otherwise "9" to get an outside line etc. The telecom service drives me crazy. I have no choice to use their phone service so they are less than helpful for any questions or requests I make. It seems I am destined to have low quality data connections. I spent a week trying to track down someone who could verify if I could get an additional line. After having half the people say yes and the other say no I finally get a definite answer. No I couldn't have an additional university telecom line and no I couldn't get a Southwestern Bell line. I could keep griping about this for a while, but I will stop. Is there anything I can do? Is anyone required to provide me with service at all? Please help me!!!!

When I used to be a customer with GTE (2+ yrs ago) one of the features I liked was the extended local calling area. I could place calls from Cleveland to Medina (a suburb of Cleveland but in a different LATA) for the price of a local call (ie. no long distance charges). When I switched over to Cellular One I lost this ability and started to be billed for LD on out of LATA calls. Since I have switched, I have talked to a few people who are with GTE (customers) and they said that the calling area is even larger now; some saying it reaches almost into Pennsylvania! I have a few questions: 1) Is there any truth to this rumor of larger local calling areas? 2) If this is still the case (free intralata calls) how can GTE afford to do this? Are they eating the cost? Or do they have their own little network? For example, say I am in Cleveland calling to Medina. Does GTE realize that this is a intralata call and thus route it over their own network to a GTE office in Medina and then place it as a local call? 3) If the above network example is true, can these companies use the same strategy and bill you anything they want? I assume this is covered is some tariffff. Well?

Mr. Nixon, 33, said that he had considered switching to the Republican Party and running for a local office. Only as a Republican can a dandidate win local races, he said. But the Lawrenceville resident said he was not ready to commit himself to the kind of campaigning that a local race would require. So he sais he opted instead to run as the Libertarian Party's candidate for Labor Commissioner.

The Trade Show/Exhibit in Signal Processing Technology and Signal Processing Based Products, and Applications will be held at the Hyatt Regency Hotel in Cambridge, MA November 3, 1992. Last year's conference and Expo. Berlin '91 attracted over 400 highly qualified design engineers and researchers from over 35 countries worldwide. The International Conference on Signal Processing Applications and Technology focuses strictly on industrial applications and product development based on Signal Processing Technology, therefore attracting a large number of application engineers with "hands-on" experience. This year's conference and Expo. are expected to attract an even larger number of attendees with a large International presence, due to DSPAssociates' recognition in the International market. A preliminary list of companies to be present at DSPWorld Expo. is given. Among them are: Analog Devices Ariel Corporation AT&T Microelectronics CADIS GmbH Catalina Research Sunnyside Incorporated CSPI Comdisco Systems Inc.

The conversation went about thus: Anonymous Phone Droid: Hello, Image Entertainment. (Much noise in the background.) Me: Yes, I'm looking for a laserdisc called, "Beany and Cecil". APD: What? I can't hear you -- the manager (!) has got a new stereo, and he's turned it up real loud. Me: Ah, well let me spell it for you. B-e-a-n-y ... APD: 'P-e-e' ... ... and so on, for about ten minutes, until finally she got to 'Benny and SeSILL' (that's how she said it!).

Date: Fri, 01 May 1992 14:41:36 GMT This is something I've wondered about for a while. Many fax switches have three or four RJ11's on them, one for the incoming telco line, and the rest to connect to phone/fax machine/modem, etc. What happens if a user connects the telco line to one of the outputs? For background, a fax switch is a call splitter; it creates battery bias for the devices hanging from it; monitors the telco line for an incoming ring, picks up the call, tries to figure out where to direct the call, rings that connected device and completes the call. It also works like a mini-pbx for outgoing calls from connected devices. What happens to the fax switch, or to the telco, or both, if the fax switch tried to drive a reverse polarity DC back into the telco line? Or, for some reason, if the fax switch tried to ring the telco line?! Since one RJ11 looks pretty much like the other, all it takes is one mistaken connection on the part of the user. Is telco electrically protected against such cases? Please reply here or email, and I'll summarize.

Point 1 : It introduces Friends and Family, saying how wonderful it is, savings etc, and as a special offer you can add *anyone* to your calling circle regardless of their PIC. This is for up to 90 days of them being added. If MCI haven't been able to convince them of MCIs virtues and change them by then -- cheerio. I wonder how much pressure they'll receive from MCI? The letter says that MCI will write or call on my behalf -- thanks chaps. Point 2: MCI World Reach, similar to something that I recently heard AT&T offering. You can now call any country served by MCI, from any country with MCI Call USA. Charges are MCI call USA rates plus 1.25/minute-regardless of the country called. Roughly speaking it is 1/minute on call USA. Does this mean I can call Austalia for 2.25/ minute? I guess this would be cheaper than using BT/Mercury/NYNEX etc? Any one care to elaborate on this payment scheme? Point 3: Using Call USA you can now reach *any* 800 number, not just MCI's. These are at standard MCI Call USA rates, and says collect calls not accepted! Point 4: Call USA expansion, now includes Puerto Rico and the US Virgin Islands, as well as the other 50 states. Quite a pleasant surprise - especially as I thought it was going to be an expensive letter.

In one of his commentaries the other day, Pat said that Compuserve charges for Internet mail. That is only partially true. Compuserve's old billing plan (now called the "alternative plan") charges each user $2 per month as an administrative charge, followed by a per minute rate that depends on the speed of your connection. There is no per message charge or surcharge for sending or receiving Internet mail under this plan. Compuserve's new billing plan (called the "standard plan") charges each user $7.95 per month. A number of services are then provided with no additional connect charges. (The most popular services, the "forums" are not included in this flat rate.) Someone subscribing to the standard plan is given an email allowance of $9 per month to cover use of the CIS mail system. However, Internet mail is not covered by the allowance and is billed on a per message basis for send and receive. One is given the option of deleting Internet mail prior to reading it if one does not wish to pay for it.

"Pac*Bell to Unveil 'Dial-a-Movie' Plan" describes a system that would allow movies to be distributed to theaters and others digitally via fiber optic lines. It would take three minutes to transmit the highly-compressed data that represents a two-hour movie. "The technology would allow theaters to instantly yank flops and order hits. Assuming licensing deals could be worked out, they also could offer a wide range of other types of entertainment like pay-per-view sporting events, operas and rock shows." There you have it, folks. Message to the EFF: Pac*Bell has not the slightest interest in offering ISDN to the masses. ISDN would only fulfill the public's basic communications requirements. It would not fill Pac*Bell's cash registers the way something as exciting as Dial-a-Movie would. So what is Pac*Bell doing to move ISDN along? Probably nothing. But I can tell you what the company is doing to push this great Dial-a-Movie idea. Pac*Bell plans to show this on May 6 at TEXPO, being held at the Anaheim Convention Center. "Bugsy" was to be the featured movie, but it contained too many dark scenes which did not show up well on the HDTV system to be used for the demo. So, "yesterday, Pacific Bell employees [on your regulated telephone nickel] were busy watching other movies and still had not decided on a bright enough substitute, a spokesman for the company said." While Pac*Bell has ABSOLUTELY NO PLANS at this time to offer basic rate ISDN to ANYONE, business or residence, it is moving full steam ahead on highly experimental technology that has the potential for the really big bucks. And it is using your captive regulated funds to do so. And here is even more irony: ISDN is technically doable today with equipment that is in place. Most film people predict that the video technology involved with Dial-a-Movie will never be able to replace an actual film presentation. Director Edith Kramer says, "You won't have the particular aesthetics of film anymore. That would be a loss for film makers and for those of us who love film." Pacific Bell's point man counters with the statement that he is concerned only with getting the images through the telephone system from Point A to Point B. "He leaves the rest to somebody else." I do not know about others, but I am completely enraged that Pacific Bell is using MY regulated dollars to go after very 'iffy' but potentially lucrative ventures, while neglecting to provide basic telephone service to the public at large. I cannot get ISDN, CLASS, and a host of other things because Pacific Bell chooses not to provide them. And I cannot go elsewhere to get them. It is time to remove the LEC monopoly. John Higdon | P.

On Thursday evening I had a great deal of trouble dialing out of the LA area. I tried a couple carriers. I have had no trouble dialing locally, however. As to the circumstances, I can't say that the riots are as much of a no deal as the earthquake of ten days ago that I did not even feel, but if it were not for the news, I would have no idea that there had been any problems. I have been impacted much more by the curfew than anything else. One night I could smell something vile, but I have smelled worse. The only other impact has been noise -- I am located near a National Guard facility and their noisy, smelly trucks have been going by a regular basis for about 24 hours. (They must have designed those trucks to be as smelly and noisy as possible). I just heard a helicopter go by, but that is not unusual. During the past 72 hours, I have heard about three sirens. I personally have not seen one fire, one looted store, any violence, or anything that could be described as newsworthy. (I am not disputing that others have, of course). David ------------------------------ Date: 2-MAY-1992 07:17:21.02 From: Douglas Scott Reuben Subject: Albany Added to NACN; Cellular Parts Supplier I mentioned that some features were working in Albany for NACN customers from McCaw systems; well, it has now been fully added to the NACN. The usual NACN problems apply: If you wish to have voicemail, you must hit *35, which will prevent call-delivery to Albany (or any NACN city), and thus calls will go to voicemail. If you use *350 (or never hit *35), calls will be delivered to Albany, but if you do not answer they will NOT get transfered back to your home NACN system. I talked to McCaw in Seattle, and the engineering VP in New York, who was supposed to explain to me why the NACN (or just NY and CT) couldn't allow call delivery AND voice-mail, and thus not necessitate the annoying *35 feature. The guy in New York couldn't answer: He just said that the MFJ prohibits "voicemail" networking between "B" owned systems and other "A" side carriers. I told him I didn't think that this was true, and that the MFJ only required that an IXC handle the traffic. Moreover, I pointed out to him that Metro Mobile is able to deliver calls in NY, and if the call is not answered, to have the call default to voicemail (or a "No-Answer-Transfer" number) without much of a problem. He sounded as if this was impossible, but said he would look into it. Although a nice guy, he didn't sound all too knowledgeable about his system, at least in terms of the specific areas which I mentioned. Does anyone know if there is some inherrent problem with Ericssons (which NY has) which prevents them from trying to deliver a call to a remote system and then if no one answers to "take the call back" and process it by sending it to voicemail or to some NAT number? The Cell One/NY guy seemed to think it simply could not be done. I would doubt this: If an older Motorola switch can do this (albeit with new software) why can't the somewhat newer Ericsson do something seemingly as simple as routing a call to voicemail if the remote system does not signal that the called part has answered the cell phone? Anyone from Ericsson or anywhere else know if this is correct or not? Metro Mobile is also joining the NACN -- no date has been announced, but calls received while in CT will now show "NACN-203" if you have a Cell One/NY account. Still no Call-delivery to Pittsfield or Franklin County, Mass -- they are looking into this now. And as an aside: If you are tired of paying ridiculously high prices for cell accessories, I saw an ad in the back of {Cellular Business} for a supply house in CA which has no minimum order and sells at large discounts. I sent away for their catalog, and found some really good deals. For example, Novatel wants to sell me an extra battery for my handheld at $54.00, the catalog sells it for $28.00. A carrying case for the Panasonic tranportable that I have has been offered to me by a cell phone store for $70; it was in the catalog for $16. The place is called Cellular Products Distributors, in LA. You can call (800) 654-3050 (or 800-443-9889 in CA) to get their free catalog. I've never ordered from them, but with some of the prices I saw in their catalog, I certainly intend to give 'em a try! Doug dreuben@eagle.wesleyan.edu dreuben@wesleyan.bitnet [Moderator's Note: Here in Chicago, Ameritech (B) transfers calls automatically to voicemail -- if you have that feature for about $4 (?) per month -- anytime they've found you but you do not answer after four rings or immediatly anytime they cannot find you or your line is busy (and you do not have call waiting on the line. Your *71 (transfer on busy/no answer), *72 (immediate call forwarding) or *18 (follow me roaming) instructions override voicemail. I do not use Ameritech Mobile voicemail, perferring to simply use *71 to my home number which in turn hits voicemail after a few rings. PAT] ------------------------------ Date: Fri, 01 May 92 18:00:38 EDT From: ddl@das.harvard.edu (Dan Lanciani) Subject: Phone Line Woes I've had two problems with my phone service recently and I can't seem to convince the repair people to help me. If anyone recognizes the symptoms and/or knows some magic words to use, please help ... 1. Starting at about 11:30 every night (became 12:30 when we moved the clocks ahead) the audio as heard by the party on the other end is muted for a split second every 5-15 minutes. I hear nothing special. No clicks, tones, etc. The only way I figured out what was going on was when people kept asking me to repeat myself. It doesn't matter whether I placed or received the call. It does appear to matter that the call is outside the local office (or maybe outside some subset of the equipment in the local office), because I can call my mother's line (in the same house) and not "see" the problem. Of course, this effect plays havoc with my modem and I made the mistake of mentioning this to the repair person. This seemed to end my chances of getting him to look more, even though the problem was initially (and constantly) noticed on voice calls. 2. More recently, I have two noises on the line. (The first problem has not gone away, unfortunately.) Sometimes they start as soon as I break dial tone by dialing the first digit. Most common is a sound just like someone's cheap-electronic-phone (tm) ringing in the background. Not the ring indicator sound you hear when placing a call, but the sound you hear from a phone ringing near your head! The other noise is pulse dialing. Sometimes rather loud, sometimes quite soft. I never hear other peoples' conversations. Just ringing and dialing. Neither of these bothers my modem, but they drive me crazy. Again the repair service did whatever it is they do to "check the line" but found nothing. When I suggested that perhaps it was something in their office, she started on how it must be my answering machine or computer or even my phone (nice, old, heavy WE version that doesn't know anything about electronic ringers). When I asked to pursue the matter further, the repair person said she didn't want to send somebody out because I didn't have a maintenance contract and would have to pay if (when?) they found a problem in my home. Finally, I had the clever (?) idea of suggesting that I would record the pulse dialing and figure out the numbers involved. She said emphatically that I shouldn't do that and that she would check the central office. This made me happy for a little while, but I don't really expect it to get anywhere. Help?

One feature of these old direct-control step switches was that (when they worked) they appeared to the sub to be almost as fast as intra-office calling on a modern ESS. Dial the last digit and !BANG! ring or busy, even when calling inter-office to another direct-control step system. This was, however, not the case with the modern 'directorized' step offices, (such as the old 366 office on the south side of Council Bluffs, the last stepper around here) where they had some kind of a common-control register-sender glued in the system between the line finder and first selector.

JSW ------------------------------ Date: Thu, 30 Apr 1992 17:11:10 +1200 From: Pat Cain Subject: Caller-ID Survey in New Zealand Telecom New Zealand (owned by Bell Atlantic/Ameritech) has commissioned an Auckland firm, CM Research Associates, to gauge public response to the possible introduction of Caller-ID in NZ. Telecom spokesman Clive Litt said yesterday it was a highly sensitive area and carried some interesting issues of privacy. "In effect there are two issues. There is the right of the person to know who is calling them as opposed to the right of a preson to keep their identity secret if they so desire. They are two very interesting imperatives and we are trying to get a feeling from the community as to how to the community believes we should handle such an issue," Mr. Litt said. People who are being surveyed are being told of some of the disadvantages (such as inadvertent release of confidential numbers to women's refuges or undercover police). And that such a system could also reduce the willingness of people to contact an agency about an embarrassing or sensitive problem (eg. AIDS hotline) or providing police with information about a crime. The perceived advantages of the service include: * an improved emergency 111 (911) response; [This seems a little strange as the callers phone numbers is already automatically displayed/recorded when such a call is made.] * a decrease in the number of obscene or threatening calls; [Perhaps Call-Trace should be mentioned as an alternative.] * better detection of hoax calls and a faster response to life threatening situations, including suicide and domestic violence. [This seems redundant as Telecom announced a few weeks ago that the police would shortly have a direct link into the Telecom call log database and would be able to lookup calls just made to calls made over the last year or so. Previous press reports have stated that they were already catching obscene and hoax callers.] Paraphrased from {The Dominion}, 30 April 1992. The article does not say whether people are being told about alternatives to Caller-ID such as Caller-ID blocking, Call-Trace, and Call-Screening. Pat Cain / cain_p@kosmos.wcc.govt.nz ------------------------------ Date: Fri, 01 May 92 11:12:06 PDT From: Michael.Bender@Eng.Sun.COM Subject: Possible Chicago Scam I just received this in my morning's e-mail and thought that the telecom readership would be interested in commenting on it: DATE: 4-29-92 SECURITY INFORMATION The following telephone number has been "found" on Sun Microsystems, Inc. telephone voice mail systems: 312-296-9000. This number is generated out of the Chicago area and the message associated with the number indicates that the caller was selected as a winner to receive free airline tickets to Las Vegas or Orlando FL. The message was generated at approximately 8:00 pm Pacific Standard Time. This number is believed to be a possible "telephone scam" type of fraud that will generate an automatic charge when accessed by the caller. The charges can be $50.00, to $200.00 per call as soon as the caller connects with the above number. If you find this number on your voice mail please do not call the number listed above, or similiar numbers. Not only will you not receive free tickets, but the corporation will be charged with the call. ----------- Is this similar to the New York numbers that bill you the $200 if you call them from within the metro New York City area, but only the cost of a long distance call from anywhere else? If that's the case, why would this scam shop bother spending their (ill-gotten :-) money calling California when they couldn't collect anything for the call? Here's what I think happened: 1. Their automatic calling equipment was mis-programmed to dial the 415 area code instead of (??) for their target market, which I think would mean that since a machine called a human that would be illegal in California (can anyone veryify this and cite any laws?) 2. The number works similar to the Mystic Marketing number where they get your ANI (but how? are they stupid enough to try to use Caller-ID?) and then somehow match the number that you called from with your address and send you a bill. Pat -- I thought that the last little flood that you had there would have drowned all of the telemarketers and phone scam artists since their main offices would have been underwater after the retaining wall broke :-). [Moderator's Note: His Honor the Mayor has explained this all very well pointing out that both telemarketers and rats are good swimmers and both species will survive, despite their nests being in the sub- basements of many buildings (which is why they are sometimes called boiler room operations.) As to the case at hand, 312-296-9000 is a harmless bunch of dweebs called 'MCS Associates' at 2708 North Halsted Street, Chicago. A nuisance yes, but harmless. 312-296 is just a regular exchange here, working out of the Chicago-Lakeview CO. They call all over the USA. Since we don't have Randy Borow to kick around any more (smile), I can't tell you anything about their calling patterns. You do not get automatically charged for anything when you call; you have to speak with an actual person, buy his pitch, etc. The rule about machines calling humans in California only applies to calls intra-state, since California cannot regulate interstate matters.

Disturbances and Telecom Greetings. I can't let statements that imply that all of L.A. is "under attack" pass unchallenged. As usual, media reports (quite naturally) concentrate on the problems, not on areas where life goes on as usual. The further you go from South-Central L.A. (an economically deprived part of town in the downtown area) the more the problems were spotty or non-existent. Yes, there were a couple of incidents in Beverly Hills. Yes, there was a hot spot in Panorama City deep in The Valley. Hollywood definitely had some problems. And there were scattered other incidents in other areas. But to portray the entire city as some sort of war zone is inaccurate. There were vast areas where life went on as usual, with no real sense that anything was going on, other than smoke blowing around widely (even though fires weren't widely spread geographically), non-stop live news coverage on all local channels (which often seemed to be showing folks in the trouble areas where to go for the best looting), and some telecom problems. According to my telco sources, almost all of the problems were caused by overloading. Slow dialtone for sure on Thursday (15-30 seconds much of the time). Trouble with getting interoffice trunks the same day ("all circuits are busy"). Calls could be gotten through with some effort. If people would just WAIT for dialtone, rather than keep hanging up and trying again when they don't get it immediately, they'd have a lot less trouble! By Friday morning, most telecom seemed pretty much back to normal in most West Los Angeles exchanges at least. It is worth noting that by Friday everything was relatively quiet and pretty much over except the shouting, which is bound to go on for quite some time. Many people in the large, unaffected areas of the city (remember, the city of L.A. is a vast place) are finding the continuing nightly city-wide curfew to be pretty silly. Many feel that it has been imposed city-wide only to avoid accusations of discrimination (e.g., why was the curfew only imposed on "poor" areas of the city?). The main effect of the curfew in many areas is that stores are closing around sundown, but there's significant traffic and people wandering about outside the core area of trouble during the evening. The irony is that now that it's essentially over, there are National Guard units being sent in and Marines are "standing by". A little fast action could have avoided a lot of grief for some people. The whole thing could probably have been avoided by some fast action at the scene of the first incident on Wednesday. The presence of military units in the central city now seems to have little point except to act as some great photo opportunities -- which people are taking advantage of by snapping away. I am not saying that there weren't serious problems in some areas. But L.A. is still here, and by and large, except in the specific areas (mostly central city) where there was concentrated trouble, it all mostly looks the same as before, with people already proceeding with their lives. One other thing. As you know, the 213/310 area code split took place six months ago. Saturday (today) was supposed to be the first day that permissive dialing ended and you HAD to dial the correct code to get through. Due to the confusion of the past few days, that cutoff has been postponed for some currently unannounced period of time. --Lauren-- [Moderator's Note: Others have said the same thing, that most of this would never have happened had authorities there made a strong stand from the beginning, with heavy armory if necessary the first night. We here were very lucky to avoid the trouble; perhaps that is because at the beginning, Mayor Daley and the Chief of Police went through the likely neighborhoods here, met with people and denounced the jury. PAT] ------------------------------ Date: Thu, 30 Apr 1992 18:39:10 EST Reply-To: Daniel Pimienta From: Daniel Pimienta Subject: Birth of the Dominican Republic Research Network It's our pleasure to announce the birth of the Dominican Republic Research Network: REDID [Red Dominicana de Intercambio para el Desarrollo] whose Association has been formalized yesterday by 25 founding members representing, directly or indirectly, 23 universities, 62 NGO's, four government agencies and three international agencies. The development of this network presents a set of originalities worth mentioning: 1] As in the case of the Peruvian network [RCP], REDID had followed the stepping process proposed by the "REDALC methodology" of UNION LATINA: -REDID gathers researchers from every type of research institution. -REDID is the result of an open, transparent and democratic process with high level of participation and decision of the end-users. -REDID is supported by several international organizations [Union Latina, Unesco, UNDP]. Special agreements have been made between UNESCO's CRESALC Office in Caracas and Union Latina's REDALC Office in Santo Domingo, to join competencies and efforts. -REDID use a UUCP protocol with gateway to the Internet. User access will be made via PC terminals connected to the national X25 network. 2] REDID users interface the central node with the MULBRI PC program [built on the top of UUPC], in its first large scale experiment. MULBRI is an ongoing development conducted by UNION LATINA to offer a multi-lingual, state of the art, PC based, interface, transparent to the types of networks [already exists a BITNET version for VM/SIMPC users, and there are plans to enhance coverage]. 3] REDID users will received an outstanding training, in July, co-organized by UNESCO and UNION LATINA. This comprehensive workshop, designed for telematics users from the research community, will gather a bunch of specialists with different skills and perspectives. 4] The node is linked to the Puerto Rico's Research Network [CRACIN] which will give it the Internet appearance. A message to USERNAME@REDID.ORG/EDU.DO will reach the UPR2 node in the Internet, then the REDID sub-system in the Codemail node will get it using UUCP protocol. CRACIN accepted to channel the Dominican traffic, free of charge, under a special agreement. 5] Last but not least, for the first time, a National Research Network receives a full range support from a National Telecommunication Company. CODETEL [a GTE subsidiary managing a predominant part of the telecom market in the Dominican Republic], is offering a logical partition inside its commercial e.mail system: the UUCP based CODEMAIL. Research Institutions members of REDID will, at no cost: -gain telephone access to the X25 network [CODEPACK] from anywhere in the country; -gain access via the X25 network to the CODEMAIL system where a limited [but large enough to cover the needs] number of mailboxes will be reserved to them; -have their traffic linked to the Puerto Rico Research Network [a well provisioned volume limit is set]. CODETEL's support stems from its commitment to the national development, but is also the right business answer to the chicken and egg dilemma which prevents the telematic market growth. The agreement will last 18 months. After that period it is expected to see REDID getting its own UUCP node accessible, via Codepack, and to maintain the other parts of the current agreement. Other companies from the industrial world will offer complimentary support to REDID. In particular, another company from the telecom environment AACR [All American Cable and Radio] is preparing the free access to some National Scientific and Technic Data Bases, and another agreement is under study with french Questel for a limited free access to some DB. The number of REDID users is expected to start at 25 and progressively grows toward few hundreds [the estimated figure for the Dominican Republic researcher population]. Part of the methodology and the results should be usable in other developing countries. Similar agreements with the telecom companies should be obtainable in various other places. The findings will be documented within a three months time frame.

The initial objective, stated during the REDALC workshop in July, 1991 [when the idea of REDID was crystallized], was to associate the Haitian researchers to the proposed solution and method. Unfortunately, present conditions in Haiti have made this impossible.

It marked what was called the longest, fastest single installation of trans-oceanic communications cable. The Global Link installed 5,621 kilometres (3,500 miles) of the next transatlantic fibre-optic cable system, TAT-10, in 21 days. This tops the record set by AT&T's cable ship the Long Lines in 1988 when it installed 5,224 kilometres (3,250 miles) of cable for the transpacific system, TPC-3. The fleet of five cable ships that is operated by AT&T lays claim to the world record for installing undersea telecommunications cable -- more than double its nearest competitors. "We've installed about 177,000 kilometres (109,900 miles) of undersea cable, 51,000 kilometres (32,000 miles) of which is fibre-optic cable. Altogether that's enough to wrap around the equator about four times," said Jim Barrett, vice president of engineering and operations for AT&T Submarine Systems Inc. AT&T also owns four sea plows and a seabed tractor, and has ownership interest in three unmanned remotely operated submersible vehicles used for cable burial and repair operations around the world. Both the Global Link and the Long Lines have the unique AT&T Bell Laboratories-designed linear cable engine that permits the fastest cable-laying speeds in the industry. The Global Link, for example, averaged 6.2 knots on its voyage. Most cable ships install undersea cable at speeds around five knots. The TAT-10 fibre-optic route will directly link the United States with Germany and the Netherlands for the first time. Service on the U.S.-Germany segment is slated for late August, with service on the Netherlands leg of the route due for service in October. AT&T announced service on the TAT-9 fibre-optic route, which links the United States and Canada with the United Kingdom, France and Spain on March 2. From start to finish, the TAT-10 undersea fibre-optic route will be completed in less than half the time a project of this size normally requires. In addition, the Global Link's operations were planned so carefully that the TAT-10 project has required fewer people than usual. A typical trans-oceanic cable operation requires about 100 people, but the Global Link had only 10 AT&T engineers on board, along with 22 ship officers and 57 crew. With the Global Link's deep sea cable operations accomplished, AT&T will now deploy another cable ship it operates to complete the remaining segment of the North Sea undersea cable operations. The AT&T-operated cable ship, the Dock Express 20, will begin working with other vessels to connect with the cable segment left off the northern coast of Scotland by the Global Link. This final leg will require the installation of specially-armored cable over 11 natural gas and oil pipelines in the North Sea. Undersea fibre-optic cable activities are also under way in the Pacific. AT&T's second the cable ship, the Global Sentinel, will begin installing the next fibre-optic transpacific cable, TPC-4, in June. TPC-4, which will link the United States and Canada with Japan, is slated for service this fall. In addition, the Long Lines will begin installing a new fibre-optic route between Hawaii and New Zealand later this year.

Apparently business associates aren't so sacred. AT&T wants _their_ numbers, so you can get a 20% discount calling them if they are AT&T customers. The advertising folks at 222-0400 should connect up with the advertising folks at 222-0300 and try to present a consistent advertising campaign. I'm not a businessman, but I wouldn't really want to AT&T calling my associates to tell them if _they_ use AT&T, _I'll_ save money. On another front, Reach Out America is increasing its evening discounts to 40% for the month of May. They don't mention that in most cases this will make it cheaper to make calls during the evening period (5-10pm Sunday-Friday) than during the night period (and _much_ cheaper than calling those coming-soon 1-700 EasyReach(TM) numbers). Finally, the 900MHz cordless phones have hit the market. A full page ad in today's {New York Times} touts the _Tropez_ 20-channel 900 MHz phone with a half-mile range. Only $299, and it's "fully digital," whatever that means. I hope some Telecom readers take a test drive for us.

The catch is that about half the communities would be subject to higher local rates (which translates to higher net local revenues).

I'll be setting up a remote office for myself in Cambridge, Mass., soon, and will be looking to set up two phone lines, with the first one to "hunt" to the second when the first is in use. A colleague who has had such an arrangement for three years said he has tried a number of combinations, and the best one is this: buy two phones and two answering machines. The reason is that, when the second line rings and I'm on the first line, I will be able to simply hit the MUTE button on the first line and monitor the second call coming from the answering machine. If it turns out to be someone important or difficult to reach on the second line, I can get rid of the first call and take the second. (Not the nicest thing in the world, I know, but hey, that's life.) I said this sounded great, but why two answering machines? He said that the double-line answering machines that he had shopped for lacked features that allow you to rewind and review messages from a remote phone, and were generally shoddily made and broke down. As a matter of fact, he told me, only the AT&T answering machine was able to stand up under heavy use of this type. Okay, said I, but why two phones? Why not a two-line phone? At this point, he hemmed and hawed and then admitted that he'd thought it through a while back and was sure there was a reason, but had completely forgotten it. So I turn to the collective wisdom of comp.dcom.telecom. What sort of two-line phone system do I need to set up here?

Both phones are the steel-base standard-issue home variety that columnist Dave Barry has said could be used as murder weapons ("Try that with today's phones!"), both finished in Regurgitation Beige color. One is a Princess touchtone circa 1972, the other a touchtone wall phone from 1980. On testing, I found that the wall phone wouldn't generate any DTMF tones with the keypad. I took it apart, hoping to find something obvious such as a broken wire, but nothing seemed wrong. I DID, however, find two wires disconnected and capped with insulating sleeves; one was gray, the other was gray with red striping. On the theory that the keypad might have been disconnected for incoming calls only, I called the previous owner, who had thoughtfully left his phone number on the telephone. He hasn't called back yet. ;-) Brainstorm! I opened the Princess phone for comparison, and found the same two disconnected wires. Now what? Can anyone tell me what those two wires are for? I'd also appreciate any pointers for troubleshooting the keypad on the wall phone if it's not going to be brain surgery.

By Adam Gaffin NEWS STAFF WRITER It sounds like the latest high-tech scam. But it could be just another urban legend. At least one local high-tech company is now warning its staff and customers about calling certain numbers that flash on their beepers or pagers. The memo says that somebody has taken to calling known beeper and pager numbers asking their users to call back. But the return number is a pay-per-call number that charges users' phone accounts $3.50 as soon as they connect, even if they hang up immediately, according to the memo. "The phone company allows the charge to be immediate, that is, no message that gives you a chance to hang up before charges start, if the charge is less than $3.51," the memo says. But a spokesman for New England Telephone says the phone company knows of no such scams and that company regulations require any service charging more than $3 to let a caller hang up without being charged. "We are not aware of any fraud that is taking place in the New England area," spokesman Robert Mudge said. Besides, of the four exchanges listed in the memo -- 540, 550, 940, 950 -- only 940 and 550 are in use in Massachusetts, Mudge said. The story, like others that have appeared in recent months, apparently evolved from some cases in New York City over the past couple of years in which the ploy really was tried, according to Steven Marcus, a spokesman for New York Telephone. Marcus said he has gotten calls from people across the country in recent days concerned about the alleged scam. The warnings have also popped up periodically over the past few months on the international Usenet computer network. One of the exchanges frequently listed, 540, is used for "premium pay" services only in New York City, Marcus said. Unlike 900 numbers, which are offered by long-distance companies that serve the entire country, 540 and other local exchanges are provided by regional phone companies, which are barred by court order from offering national services. Marcus said that even if a Massachusetts caller did somehow get connected to a New York 540 number, he would not be billed for more than the cost of a regular long-distance call to the city. This is because regional phone companies, such as New York and New England Telephone, do not share information about rates for billing users of these premium-pay services. "I am totally puzzled" by the stories from non-New Yorkers, Marcus said. Marcus said that in the few cases New York Telephone has dealt with, the company succeeded in getting the company involved to stop. The practice violates state-approved company regulations that require providers of such services to detail their costs in ads, he said, adding that the company considers leaving a pay number on a beeper to be advertising.

They set up two accounts for me -- one personal and one business. It took about two weeks and I got the information in the mail the Thursday before Easter. I tried the personal account on Saturday. The initial voice prompts are a bit scratchy and could sound better; entering the PIN gives the second prompt and you are off to the races. Voice quality on calls was no different than calling via Bell Canada as far as I could tell. PROBLEMS ENCOUNTERED: 1. They only allowed six rings before dropping the call. 2. PIN for the company did not work. 3. They did not recognise the buisness line automatically. I called in on the customer service line and very quickly was passed on to the techies as it was 'a technical problem'. The tech told me a) the six rings limit was deliberate and when I complained and explained that it was causing problems he said it would be changed to a higher limit (10) I suggested higher as some answering machines need more to turn on. It appears that it has been changed(04/26 was my last try). The PIN problem he said he'd have to check into and get back to me, he called back about 15 minutes later to tell me the letter had the wrong PIN, and gave me the correct one. (NOTE 1) The problem with the ANI was that it had not yet been programmed but should be in place by May 1st. When I signed up there was a $24.95 fee, that was offset by 6 $5 vouchers that they were including, so at least if you can keep it going for 5 months it wont cost to sign up (offer may have ended by now). I have yet to try with a V.32bis connetion but I've used it for fax with no problems. peters@beltrix.guild.org or torag!beltrix!peters ------------------------------ End of TELECOM Digest V12 #359 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa29736; 3 May 92 23:37 EDT Received: by delta.eecs.nwu.edu id AA06680 (5.65c/IDA-1.4.4 for telecomlist-outbound); Sun, 3 May 1992 21:46:52 -0500 Received: by delta.eecs.nwu.edu id AA19543 (5.65c/IDA-1.4.4 for telecomlist); Sun, 3 May 1992 21:46:44 -0500 Date: Sun, 3 May 1992 21:46:44 -0500 From: TELECOM Moderator Message-Id: <199205040246.AA19543@delta.eecs.nwu.edu> To: "\\telecom"@eecs.nwu.edu Subject: TELECOM Digest V12 #360 TELECOM Digest Sun, 3 May 92 21:46:45 CDT Volume 12 : Issue 360 Index To This Issue: Moderator: Patrick A.

In the simple of case of IXC hacking, the IXC has to pay real money to the LEC on each end of the call, even if it is off-peak. The IXC may incur no marginal cost to carry its part of an off-peak call, but it looses real money by having to pay the LEC. Also, what about the case of international calls? Certainly may of these phreaks will want to cash in on their skills (especially if it is not illegal!) They can sell their "call setup" service to people wanting to call expensive foreign lands. Again, the IXC looses big bucks to the foreign PTT. Oh, by the way, when are you next going on vacation?

Brad pointed out that, at least if they number below some level, hackers do not impose marginal costs upon the phone network. He's right. Pat's analogy to MasterCard is completely inapt, since hacking MasterCard requires the issuing bank to shell out cash. Another poster made a much better analogy; namely, that of people who sneak into a movie theater. No marginal cost is imposed. Now, Pat is 100% correct that property rights ought to be respected, and vendors are entitled to payment whether or not a marginal cost is imposed. Furthermore, the absence of marginal cost is true only up to a point. If it's too easy to hack, so many peoplewill do it that the networks will both lose revenues and experience pressure on capacity. Without conceding that hacking should be legal, I do think Brad made the valid point that, absent a marginal cost being imposed on the telco, enforcement of the law ought to be a low priority.

One point that I haven't seen brought up here is that if the phreakers are not stopped, word would get around and those 1000 phreaks will multiply. This will eventually cause the phone company to have to add more equipment to handle the calls or catch and prosecute the offenders. So, if they go on a prosecution binge every now and then, people won't abuse the system as much. Even if the amount of damage done by one individual is almost nothing, multiply that by hundreds of thousands, and you begin to have real losses.

Pat's reply to you covered the fact that telco's have property rights just like credit card companies. But even without that, your assumptions just don't hold water in a post-divestiture world. Let's face it, nobody is going to phreak local calls, they are going to phreak interexchange or international calls. These calls involve multiple carriers. The fact that a phreak manages to get the billing for the minutes to go off into the ozone does not prevent the local exchange carrier from collecting access charges from the interexchange carrier. That's real money, Brad, leaving the accounts of the IXC and entering the accounts of the LEC. If the call is international, add to the LEC access charge the settlements charge to the PTT on the foreign end of the call. That is usually a substantial charge, much bigger than the LEC access charge, which isn't peanuts. That is real money leaving the IXC account and entering the PTT account. If that's a victimless crime, then what are the shareholders of AT&T, MCI, and Sprint, chopped liver? ------------------------------ From: peter@taronga.com (Peter da Silva) Subject: Re: Moderator's Surprise Organization: Taronga Park BBS Date: Sat, 2 May 1992 04:08:02 GMT In article mc/G=Brad/S=Hicks/OU=0205925@ mhs.attmail.com writes: > Let's suppose that there are maybe 1000 phreaks in this country who > have the technical know-how to bypass the telcos' billing systems and > make free calls. Off-phreak pricing, eh? (sorry, I couldn't resist) How to justify this message: With 1000 phreaks, you probably won't have any problem. With 1000 people littering, you probably don't have a problem. With 1000 people sneaking into movie theatres, you probably don't have a problem. With no social sanction, and an immediate profit, it's not going to remain 1000 phreaks, litterers, or sneaks for very long. Pretty soon you DO have a problem. I suspect that it's not going to remain legal for very long. > Littering is illegal. Shall we hire as many cops as it takes to catch > every litterer, and fine them enough to pay the costs? Nah, but you can catch enough to make sure there's a reasonable expectation of a social sanction if you habitually litter. Low cost, low return, but it does cut down on the number of people you need to keep the streets clean. > Don't forget those social costs.

But on the other hand, one might ask the question "Why do some people feel that it's okay to steal from the telcos when they would not steal from a home or a store?" I'm not coming to these people's defense, but I would submit that it's possible that there's an element of "as ye sow, so shall ye reap" here. In my opinion, the telephone companies have not played fair with their customers. There have been numerous examples of this posted in the Digest (first example that comes to mind: charging extra for Touch Tone service. There are probably even better examples). The problem is not helped by the fact that the local telcos are a monopoly, and therefore customers have nowhere else to turn when they are dissatisfied. And at least some telcos tend to have a real attitude problem ... they know you don't have other choices, and their not above gloating about in, in their own way. None of this excuses the ripoffs, but if you are asking the question "Why are the telephone companies the target of this sort of victimization more than other types of companies", I would say that in some cases it is the chickens coming home to roost. Of course, there will always be some who will try to rip off the phone company, but my guess would be that once full local competition arrives, it will be FAR less socially acceptable to phreak (even among the groups now inclined to do so, e.g. technically-knowledgeable college students). To any phreaks reading this: The PROPER outlet for your frustration with the local telcos is to lobby your PUC and/or state legislators (or the equivalent thereof in your location) to change the regulations to allow local competition and/or to put a stop to whatever telco practices you feel are wrong, and NOT to try to use illegal means to get compensation for whatever you may think the telco "owes" you.

PAT While I agree that the property right of all must be upheld to make them worthwhile for us little folks, and I am more sympathetic to the LD providers now that they have to slug it out daily in order to make a living, and I do NOT advocate any illegal activities in opposing the power of the LEC ... I do empathise with anyone who wants to rip the daylights out of their big, faceless, over-fed LEC. Around here, they buy our PUC wholesale and add only services that are easy to market, cheap to provide, and don't cause a stink if they overcharge. To be fair; Some of the nicest and most helpful folks that I have met work for our LEC. And I don't mean to disparage their help in many matters. But the sum of the whole of them and their managers is a frightful mess which is impossible with which to work unless one is a fatter, meaner corporation.

PAT] ----------- Pat asked me to write an article about a personal experience I have recently had with toll fraud. Because of the embarrassing nature of the problem, and to avoid having more phreakers target us, I have asked that Pat not reveal my name, or the name of my employer. I work in the communications department of a large Pacific Northwest organization (206 area code). In March, we were hit for thousands of dollars in toll fraud. The fraud will have a real impact on our department, our ability to service the rest of our organization, and the product that we provide to our customers. As is always the case, the cost of the clean up may be greater than the cost of the problem. Those of you who are out there stealing long distance services, please stop. It hurts a lot of people. If you find, or hear about, a hole in someone's telecom network, please let the owner know. Don't tell me about the phreaker providing a valuable service by pointing out flaws in a network, that is just a second class rationalization for your harmful actions. In February our department began receiving complaints about phone calls made by automated devices. These calls all seemed to come in during late afternoon early evening hours. When the called party answered, all that was heard was a modem/fax like tone. We determined that the incoming calls seemed to be moving sequentially through our phone lines. We tried to transfer some of these calls to a modem and a fax machine. The modem would not handshake with the tone. The fax machine printed a "1" in the middle of a two inch page. While I don't know if these calls are related to our fraud, the timing makes them suspicious. Shortly after that, I read a TELECOM Digest article by a Canadian/English author that mentioned a "friend" in the 206 area code who was helping the author reach American 800 numbers. The impression I received was that the "206 friend" had established some kind of trunk to trunk conference on a standard phone line. The foreign author would call the "friend's" phone number, and the "friend" would pick up another line, dial a requested 800 number, and allow the author to complete the call. For those new to the Digest of Telecom, persons outside of the United States are generally not able to call US 800 numbers for a variety of technical and billing reasons. This is doubtless frustrating to people who get American periodicals and want to order things from companies who only list an 800 number. I thought the "friend" was a kind hearted person indeed. Then I read (Pat's) Moderator's Note at the bottom of the article. (In the past, these notes have caused me to question Pat's objectivity. This note saved us tens of thousands of dollars. I will question no more.) Pat stated that this "friend" was probably an unrestricted DISA port, and that some poor company's phone lines were being used without their knowledge or permission. Note -- DISA stands for Direct Inward System Access. It is a feature available on many phone systems, including the systems that we use. Our organization uses relatively small phone systems at each location, rather than one large PBX. DISA allows a caller to dial a phone number that is answered by the phone system. Generally the phone system answers with dial tone. Callers may then dial the intercom number of someone on the system, getting a call directly to an internal party without having to take up the time of a receptionist. In some cases, the incoming caller can also dial "9", get an outside line, and dial a long distance phone call. Most companies restrict this feature in some way. The modem/fax calls that we had received, coupled with Pat's note formed a critical mass when a co-worker stated that she had a complaint from one of her user groups about some weird calls on their February phone bill. As the amount was only about $300.00, no one was really too concerned. There had been a disgruntled employee recently terminated from that group, and this was thought to be the explanation. I asked the co-worker if that group had DISA. It did. When I tested the DISA, I found it to be unrestricted. I then tested all 30 systems with DISA, and found eight of them were completely unrestricted, a violation of our internal policies. By this time it was late March. At my request, Pat asked Digest readers to tell him the phone number of the "friend in 206." No one volunteered any information. Then came the March long distance bill. I sent the message below to Pat. [Moderator's Interuption: Before we get into that, I should say that I did receive one message -- from the UK writer whose 'friend' was making those calls. He merely repeated a number which had already come to your attention ... PAT] ----------------- Pat- The gruesome truth is in. Our DISA was being hit for toll fraud. The initial report that I received was that calls were coming from a 702 number in Reno, going to Canada. This seems backwards to me, but I will know more later. On the one system where we were alerted to the problem, there are several thousand dollars worth of fraud. It appears that they only found the last line in a five line hunt group. I am so glad that they didn't get the lead number. I still don't know if they found any of the other unprotected systems. I am pretty upset with the person who left them open; I can't believe the head in the sand attitude that some people have. I can't count the number of times I have seen warnings in professional journals, or even the general press, about guarding DISA ports. Her reaction to this problem was a sort of "huh?" In any case, thanks for your assistance in helping us try to find the leaks. The Digest saved us thousands of bucks. If I hadn't seen the article from the guy with the "friend in 206," coupled with your commentary, I probably wouldn't have started closing the holes until this month's bill came in. As fraud tends to grow every month, this probably would have become a REAL problem. In any case, I will never again question the placement of your Moderator's Notes. :) If you happen to hear of any other potential problems like this, please let me know. ----------- I really doubt that we would have figured out the problem in March without the Digest. By the time we would have received it in April, the charges would probably have been astronomical. Because of the way the charges appeared on our bill, we may not have figured out that we had a DISA leak for even another month. Pat's comment really saved us. Thank you Pat. To the phreaks: Shame on you. If you would like to send a message to me, and if Pat is willing, please send it through him.

Do > I have all that correct? PAT] Not quite. My phone bill was only one month overdue. I.e. I had not paid a bill due mid-March (oversight) and then I got the April bill which showed the outstanding amount. I of course being a conscientious bill payer fully intended to pay both of them. Then I went of holiday for a week and during that time the Telco called me nine times on the same day. Since their machine had assumed the message had been delivered since the phone was answered nine times by my machine a week later my phone was cut off. This is a new "service" and some warning might have been appreciated like a note in my current bill that I had an unpaid amount and if I did not pay by a certain date the phone would be disconnected. One month's overdue is hardly a capital crime and I am sure we all have forgotten about a bill every now and then given so many arrive all at different times. I would be interested to know how people in the US would react if their Telco's did the same given the much higher penetration of answering machines over there and much stronger consumer advocacy groups. LD competition has improved LD service immeasurably here. Notwithstanding the fact that the local Telco is owned 100% at present by two BOC (Ameritech and Bell South?) when a new LD player came along and offered lower prices and six second billing for domestic LD Telecom had to follow. Then the alternative LD offered lower international and one second billing after the first minute (very useful when you send faxes) and again Telecom had to follow.

Of course we might have an equivalent of 800 numbers that bill, too, but I haven't heard of such a thing. I tried the number, it just rang, no pickup. I don't know what Gateway is, anyhow (maybe they're not up yet? It's 6:27AM EDT right now), or how the seven digits following the 177 might map into the US. I use 177-100-2727 to get to ATT's USA Direct. My guess is that there are other services that use a 177 number that is answered abroad. How these services pay for the cost of the 177 line, I suppose is up to them. BTW, has anyone ever asked the USA Direct operator in what part of the world he or she is located? Are they in the region where the 800 area code is located :-)? (a skit on Saturday Night Live once had 800 be the area code of a place where all the inhabitants made their living answering the phone.) warren@nysernet.org [Moderator's Note: The USA Direct operators are located in the IOC (International Operating Center) of AT&T in Pittsburg, PA. Is there any particular reason our correspondent could find nothing published in the phone books there about 177 or could find no one at telco to discuss it (or claims he couldn't)?

I will occasionally be using this phone in areas which will require a high performing phone to succeed. I am interesting in experiences good and bad with any of the hand-held phone. Right now, one of the ones at the top of many people's list in the durability, performance and battery life category is the Motorola Micro-TAC series of phones. They are claimed to be very durable (can take big drops and still function), perform very well, and long life battery gets it up to 24 hour standby, 120 minute talk. Very respectable. However its 7-segment display seems to be far to small to be useful. Manuvering through the menus is painful, and time consuming. On the service front, some outlets will be outfitted with equipment which will download the entire state of your phone into a loaner while yours is out for service. Very handy. The other one that looks very promising is the new NEC P400/P600 series of phones. The P600 is the P400 plus alphnumeric, plus a few more features. It has a nice 42 character, multiline display which seems like a big win. Its size is very smaller and has very high performing batteries for its size. Its high capacity batteries do 24 hour standby and 120 minute talk time. It also apparently has an extenable antenna so flexible that you can tie a knot in it. I have only seen a dummy which does not have the antenna attached. I am very interested in experiences with this phone. This also runs about $100 cheaper than the Moto, but I am not sure it is a comparable package (batteries, charger, etc). Also I would be interested in good and bad experiences with any of the Mitsubishi/DiamondTel, Fujitsu Pocket Commanders, OKI, etc. BTW: Do these passive repeaters really work?

Ormos" Subject: Advice Sought: Portable Cellular Phones My sisters and I are looking for advice on buying a light-weight (i.e. less than one pound) hand-held portable cellular telephone as a gift for our parents. There seem to be many models available, and we are finding it difficult to differentiate between them. As usual, the salespeople with whom we've visited have provided little assistance. Our primary goal is to provide a convenience for our folks; we don't expect them to use the telephone much. We would also like them to feel safer by being able to call for help in case of car trouble. They occasionally travel through rural areas so we thought it would be a good idea to be able to connect the telephone to a permanently mounted vehicle antenna, when the phone is to be used in the car. Our folks are technologically unsophisticated, so we are more concerned with quality and reliability than whiz-bang features. I've listed a few specific questions below, but we would be interested in any general comments people might have. 1. Which hand-held models can be easily connected to an external antenna? A few of the lightest phones we looked at, particularly the Motorola "flip-phone" models, appeared to have a permanently installed antenna and to lack an antenna socket, but we were looking at mock-ups, and not actual phones. Can these light-weight phones be adapted for an external antenna connection? 2. Do any brands or models have particularly good or bad reputa- tions for reliability or quality? 3. Is an external vehicle antenna necessary for reliable operation in rural areas? 4. Is the limited transmitter power of a hand-held phone a significant handicap in actual use? If so, is this handicap eliminated by connection to an external antenna? 5. Are the battery life specs provided by the manufacturer (i.e. talk time/standby time) realistic? 6. Do any models have batteries which are particularly easy to remove, recharge, and install? 7. We've seen brochures for some phones advertising around 2400 channel capacity. Do all modern phones have this capacity? We would appreciate comments from anyone who has experience with one of these phones or who has studied them recently. Suggestions or experience with a particular model, or "Street Prices" for various products would be very helpful. Thanks for your help. I'll post a summary of responses if there's any interest. neil ormos wd8bdp thssno@iitmax.iit.edu ------------------------------ From: doug@cc.ysu.edu (Doug Sewell) Subject: Re: GTE Mobilnet in Cleveland, OH - IntraLATA Call Questions Organization: Youngstown State University Date: Sun, 3 May 1992 13:43:41 GMT In article Jeffrey Wisniewski writes: > In Cleveland Ohio, GTE Mobilnet is one of the cellular carriers.

I have Cellular One service out of Youngstown, OH and have the extended local calling service all over area code 216, which covers the Youngstown-Warren, Cleveland, Akron, and Canton (maybe the last two are actually one) cells. If I remember right, I can call anywhere in Ohio for very reasonable rates (I think it might be air-time only), as well as to Pittsburgh PA. Wilcom/Cellular One here also provides the standard perks (forwarding, three-way, call waiting) in the standard $20/month plan, and also has automatic "follow-me" roaming free throughout Ohio (well ... one of the major cities has a roam fee that applies, but that's the extent of it). Nationwide automatic roaming is $2/month additional, but I don't use it because when I'm out-of-state I don't WANT to be that available (and I don't want the roam fees). Incidentally, air-time is $.35/minute all day. That was a trade-off -- "with all the new features we've made available to you, we feel you won't mind that we're dropping the $.20/minute non-prime-time rate". Didn't matter to me ... 80% of my calls were prime-time (8am-8pm) anyway. I suspect part of the difference between C1-Cleveland and C1-Youngstown is that they have to throw in extra perks here in Youngstown to get buyers, where there's more willing buyers in Cleveland. Locally, Centel offers just about the identical package. Now, for your real question: how can they do the intra-lata calls and bill them as local? I suspect it's because they're using their trunks and/or the mark-up for air time over their cost more than covers it.

When I used to be a customer with GTE (2+ yrs ago) one of the features I liked was the extended local calling area. I could place calls from Cleveland to Medina (a suburb of Cleveland but in a different LATA) for the price of a local call (ie. no long distance charges). When I switched over to Cellular One I lost this ability and started to be billed for LD on out of LATA calls. Since I have switched, I have talked to a few people who are with GTE (customers) and they said that the calling area is even larger now; some saying it reaches almost into Pennsylvania! I have a few questions: 1) Is there any truth to this rumor of larger local calling areas? 2) If this is still the case (free intralata calls) how can GTE afford to do this? Are they eating the cost? Or do they have their own little network? For example, say I am in Cleveland calling to Medina. Does GTE realize that this is a intralata call and thus route it over their own network to a GTE office in Medina and then place it as a local call? 3) If the above network example is true, can these companies use the same strategy and bill you anything they want?

If you do not press "END", is there any auditory feedback that you have not closed the connection? (like on home phones) 4. Do you clear the number in the display when you are finished with the call or just before entering a new number (assuming time between calls)? 5. When talking, can you clear the number from the display before pressing "END"? 6. Do you always have to clear the display to enter a new number after a call, or can you "write over" the old number? 7. When receiving an incoming call, is the number in the display automatically cleared? 8. When you finish a call, and assuming you are not about to make another call in the near future, do you turn the power off? 9. Do you pick up the 'phone to dial, or do you dial it while it is still in the cradle? [Moderator's Note: As stated above, send replies to the persons collecting them -- NOT here to telecom. Thanks.

I have a Motorola bag phone that came with an eight inch rubber antenna and a magnetic mount car antenna. I decided that I didn't want to leave the window open for the cable on the outside antenna, so I tested with just the little rubber one. I made a round trip between Eastern Massachusetts and North Eastern New Jersey. The only area I had trouble with was from the Sturbridge MA area to the CT border. The phone was set to B carrier only. In this area it kept going in and out of ROAM mode and a few brief times it lost service. My questions are as follows: 1. If I had been on a phone call in the area where it was going in and out of roam mode, would the call have been dropped or passed off to the other system? 2. Would the results have likely been different if I was using the outside antenna? I was in Fair Lawn which is between Paterson and Paramus. Before leaving Massachusetts, I checked with Nynex and was told that the area was covered by Nynex. My roaming guide from Nynex does not list an A carrier for that area. I used the Nynex access port in Newark which worked fine when I tested it. What confuses me, is my understanding that the B carrier in any area is always the wireline carrier. The wireline carrier for the area I was in was not Nynex, but Bell Atlantic. I then looked in the Yellow Pages and found four different cell phone companies listed. (Nynex, Bell Atlantic, Mobile One, and Cellular One.) Can someone out there explain this?

Since they started selling cellular phones, Radio Shack has also been carrying TNC-to-BNC and BNC-to-TNC adapters. I use them to jump back and forth between the 1/4-wave whip on my handheld and a side-window clip-on in my car. For Radio Shack stuff, they're pretty high quality. I've been using the same set for a couple of years now, several reconnects per day, and the BNC males haven't gotten too wobbly (a common problem with cheap BNCs). And having the adapter pair in series with the 1/4-wave whip doesn't seem to have hurt the impendance match at all. In fact, I recently took advantage of PacTel Mobile's "free cellular checkup", and the service guy's VSWR meter said that the whip+adapters combo was ever-so-slightly better than the whip alone.

My ham radio HT's get warm faster when I drop from high power to low power. I measured the current drawn on one and found it reduced only slightly on low power. So just how much saving of battery life you get will depend on many factors such as the design and battery voltage relative to the range the unit accepts.

My background includes high speed data communication applications and technologies so when I developed an interest in cellular networks, I thought (as many of you did) that these networks would not be feasible for a number of reasons including reliability and cost. Well, just like every other technology, it's application dependent. For many data transmission applications, cellular networks are proving to be both reliable and cost-effective. Here are some of your remarks: Gerald Peppers, gpeppers@hns.com, replied that {Cellular Business} magazine detailed phones that allow you to send data over cellular. I'll check it out. After checking with a couple of providers, indications are that the interface between lap/notebook modem and cellphone is via RJ11 (NEC's smart RJ11 seems to be popular). Aaron Rosenbaum, root@gamma.com, Gamma Consulting, reports that Apple's PowerBook is ideal for data and fax communication. Aaron points out that the PowerBook is the only notebook on the market that can receive faxes while powered off. The PB "sleeps", but when a call comes in it wakes up, accepts the fax then goes back to sleep. Good point, Aaron, my PC-compatible laptop would have to be powered on to accept data/faxes. Aaron connects the PowerBook to his cellphone with the NEC smart RJ11 interface and is probably reading this in his car. timo.pelkonen@hut.fi remarks that error correction is essential because "cellular nets switch channels from time to time". Also says that 1200 (v22) works better than 2400 and batch applications are better than interactive "because of the delays caused by errors". John Anderson, andrson@rtsg.mot.com, forwarded a copy of the Ericsson GE Mobidem press release that included details on its use with the HP 95LX palmtop computer and Anterior's Radio Mail. Mmmm, pretty hefty both pound-wise and price-wise, don't you think? (email me or John for a copy of the release). The Mobidem is designed for use on radio networks, not cell (but, thanks anyway, John). Scott Kludge, kludge@grissom.larc.nasa.gov, says cellular modems are available w/ 2400 being about the max. Cellular nets have a tendency to drop connections at handoffs every once in a while. Cost is the same for your average cell call -- "damned expensive". Bill Kennedy of San Antonio, bill@carpet.wlk.com gets 90% of his news via cellular communication (including TELECOM Digest). His comments: speed is 1200 bps, his particular cellular call plan provides "free" time from 2000 to 0700 weekdays and all day on weekends, so he takes advantage and obtains approx. 6,000 free minutes per month. Mike Bray, mike@camphq.FIDONET.org is not currently using cellular, but expects to. He's looking for advice on phones and RJ11 interface. Lonnie Filbrun, lfil@athos.az.stratus.com, says "yes, it works but boy, it can be VERY expensive". Did a test in Phoenix using USWC net. No probls exp. at 1200/2400 rates. USWC pals use faxes in their cars at 9600 (MNP fax modems). Lonnie suggests optimizing your use of cellular data transmission by only sending necessary data, formatting and sending data packets in batches, i.e., "dial, connect, dump packet, disconnect". (Lonnie, I'm not surprised by your remark on cost in light of a recent conversation with a USWC sales rep who said their rates are probably going to go up. Great sales pitch, eh? Other carriers, like McCaw, say the trend is the other way. Rates or at least billing on data calls should decrease.) KRUSE_NEIL@Tandem.com tells about a Cellular Data demo he recently saw. CDI has their own X.25 over cellular for use in credit card verification and other transaction applications. Jim.Rees@umich.edu, Jim Rees says no problem to 2400 baud data (no way at 9600 or 19.2) and discussed cellular modems. (By the way, the recently announced CelluPlan II will boost data rates to 19.2.) Thanks to all of you for your responses. I have also recently been discussing cellular data communication with some of the cellular carriers and I know that most of you with an interest in this area have already heard of the IBM CelluPlan II trial with Sears that's scheduled for this summer. I expect to see the utilization costs (on cell nets) decline while the reliability and performance (speed) increases. Any comments, questions, please email me and I'll sum. What's next, satellites?

Shelton) Date: Mon, 04 May 92 11:21:53 -0700 Subject: AT&T 700-Number Service: What a Crock! What a crock. AT&T has come up with a new way of confusing things. Why do I want to pay money for a "lifetime" phone number that has similar (but worse) behaviour than 800-service. Consider: 1. Area 700 is "special"; it's the only area code in which each LD provider has it's own "namespace". My phone number (700) CALL-MOM in AT&T land isn't the same as MCI's (700) CALL-MOM. And the cost to the caller could be different, too. 2. Because of (1), I would have to tell all my callers to dial 10288 1 700 CALL MOM (16 digits) instead of either seven or ten digits. 3. Like an 800 number, AT&T is asking me, the recipient, to pay for the calls. That's not a feature for me. With no set procedures for area 700, they could have placed the burden of payment on the caller, not the recipient. 4. While I can change the routing for my 700 number, Cable & Wireless has allowed this feature for 800 numbers for a while. 5. Bell Atlantic will be allowing reprogrammable LOCAL numbers soon. And, they will offer scheduling (send calls to home from 5pm to 8am, to work from 8am to 5pm, and to my beeper if no answer after N rings.) AT&T isn't offering these features (yet.) Bottom line: Big Deal.

I tried to think of why I would want it. I still haven't thought of a reason. The phone number can follow me wherever I go. So when I move, I don't have to call everyone I know and give out my new phone number. But if I only give out my 700 number, I will be hit with a lot of forwarding charges. So to avoid those charges, I give out my local number. Then I'm back to where I was. If this is the first step in implementing personal telephone numbers for everyone, what will happen when all 700 numbers are exhausted? How is this whole thing implemeneted? Is there a central database of forwarding information? When this gets big, how will such a giant database work? I fear that if we are aiming for everyone to have a personal number, following each of us wherever we go, it will be expected of us to be reachable at all times. We will lose the advantage of being able to walk away from our phones. Who can make the best use of this new service?

While that may be true, the applicable problem that AT&T's service seems like it will fix is the ability to make the changes in where your calls are forwarded as you move around. I had been wondering how I might set up a system whereby I can call in to home on one line and connect into the other line and make the changes. It would have had to be a secure system to make sure I don't hand over my dial tone to someone else. But it looks like the AT&T service will do this for me with features.

The Tadiran is a truly fine product. It's DC based power system make battery back up cheap, easy, and strongly recommended. The hardware is very solidly built both in the cabinet and at the set. The field upgradability of the sets is really nice. The ability to replace any board in the cabinet, including the CPU is tremendous. I did wish that the phones came with more dedicated fixed feature keys (last number redial, etc). Putting routine features on the phones gets a little button intensive, consider more buttons on each phone. The PC operators console was VERY nice. Reliability is high, and the Tadiran people in Florida really know what they are doing. Good technical support. If it has the features and price you are looking for (and it probably does), you will be happy with it for a long long time.

This thread has given rise to an idea for a product that somebody ought to develop. I realize there are probably EXPENSIVE commercial systems that may do something like this already, but I'm talking about something that would be affordable to computer hobbyists and small businesses. Here's the proposed product: Hardware: A plug in card that would occupy one slot in an IBM (or compatible) computer (XT or AT clone). The card would have the following connectors on the rear: 6 conductor telephone type jack Audio out jack (line level) Headphone out jack (would drive stereo headphones with mono audio) Audio in jack (line level) Microphone in jack Microphone hi/lo impedence switch Also, a telephone type handset would be provided which would plug into the six conductor telephone jack. This handset would contain: Telephone type earpiece -- GOOD quality microphone capable of high quality speech recording (i.e., NOT your typical cheap carbon granule microphone). Momentary contact switch (normally open) switch in handle. Each of these would have its own pair of wires in the handset cord which would connect to a pair on the six conductor plug that inserts into the card. Plugging in an external microphone or audio source would disable the handset microphone (unless you want to get fancy and have the inputs software selectable). This card would take audio or speech and digitize it into a byte stream which could be stored in a file OR sent out the COM port. The card would also take digitized audio and decode it back to "real" audio. Now, in typical use you'd press the switch on the handset, would would indicate that the card should begin capturing and digitizing audio, and you'd release it when you are through speaking. But the state of the switch could be ignored when desirable. Basically, the switch would just be an aid to the system in helping it determine whether actual sound is present or not. In effect, when the switch is NOT pushed, any sound would be considered "background noise" and ignored. The software supplied with the product (or by a third party) should ideally allow selection of the sampling rate of the audio signal (more on that in a moment), and also allow one to specify that the handset switch is to be ignored. And, it should allow the digitized audio to be sent directly to and received directly from a COM port (and therefore, a modem). It should also allow a choice of minimal error detection and correction (only as much as can be done in "real time") or full error detection and correction (it will try as many times as necessary to transmit the data error-free ... usually you'd only use this if the digitized data were being stored on a hard drive for later replay at the receiving end). It should also allow NO error detection, for cases where freedom from errors is not as important as speed of transmission OR for cases where the modems themselves are doing the error detection and correction. Now the question is, if you put audio into this thing, would it come out the other end in "real time"? That would depend upon several things, including: 1) The sampling rate used ... a higher sampling rate would give you better bandwidth and a better quality signal, but if you overrun the modem's transmit speed, there might be gaps (short pauses of silence) at the other end as the modems "catch up." In that case, you'd either use a lower sampling rate (losing audio clarity) or store the speech for later playback. In some situations, it might be desirable to record a few seconds of speech (using the handset button to indicate start and end of the message), let the system transmit it, store it on the other end, and then play it back when the entire audio segment is received. This would provide "not quite" real time speech, but of considerably higher quality than would be possible over a normal phone line. 2) The amount of noise on the phone line, 3) The level of error correction used, 4) The speed of the modems involved. The uses of such a unit would be fairly obvious ... anytime you need to transmit audio of higher than normal quality via a phone line, you could use this thing. If it could be made affordable, every radio and TV journalist in the country would want one. And computer hobbyists would want them as well. I envision that with the proper software, a BBS user could hold a nice voice chat with the sysop, while downloading a file simultaneously. Of course the software would have to disting- uish between voice and data "packets", but it could make use of silent periods in the conversation to transmit data. Or digitized voice or audio could be stored and forwarded via a packet switching network, perhaps in semi-real time. Imagine an audio journalist caught in a situation where the telephone lines are poor quality and/or nearly unavailable, but the packet switching networks are open and working fine. An audio report could be digitized and sent back to the home office. Imagine taping a short recording for a friend (say three minutes of music, talk, or whatever) and sending it across town or around the world in digital format, so that the recipient would get audio of the highest quality. Even if a three minute segment takes 20 minutes to send, it may be considerably less expensive than other available means. (Actual case in point: I know of a weekly radio program on shortwave that gathers three-to-five minute reports from various correspondents. When they phoned in audio reports, the audio quality was terrible and listeners complained that they couldn't understand. So now the correspondents have to Fed-Ex in tapes. That means late-breaking news can't be included, and there's a weekly expense of around ten dollars. If those segments could be digitized and transmitted over the phone lines in, say, half an hour online (which is probably much longer than it would actually take), the cost would still be less than one-fourth of Fed-Ex, NOT counting the pickup charges or cost to take the tape to Fed-Ex). Yes, I know there is EXPENSIVE equipment that will do things like this, but ... I suspect that "hobbyist grade" equipment could be made for much less money AND would ultimately do a better jobe than the commercial stuff (just as much home stereo equipment outperforms the equipment your local radio station uses). Please remember me if you make a million bucks with this ... :-) > It depends. I once saw a demonstration of a low bit-rate secure voice > system that operated at 300 bps!

Now THAT raises interesting possibilities. Suppose that you could have a phoneme coder/decoder running all in one box (forget modem transmission for a moment)... would this not provide some possibilities for changing speech? For example, let's say that you played the soundtrack of a few old W.C. Fields movies into a computer (only the parts where Fields is speaking) and had the computer "learn" all of Fields' speech patterns. Then I recorded the same words and phrases using my voice, and let the computer "learn" my speech patterns. Then the computer was programed to detect phonemes in my speech and replace them with the equilavent phonemes from Fields' speech. Now, let's suppose we do all this on a relatively fast system (a '486 box may well be plenty fast enough). I could speak in real time, answering any questions put to me, and it would all come out in W.C. Fields' voice... and it would actually be segements of HIS voice electronically "spliced" together, not MY voice reformed to sound something like his. Now, that may sound harmless enough, but suppose that instead of using W.C. Fields' voice, I used the voice of the President of the United States? Can you see where that could possibly cause some problems if misused? I'm afraid that the day is coming (and is already here, in many ways) where we will not be able to believe anything we see on television or hear on radio. If you saw the segment on "Prime Time Live" a few weeks ago on "morfing" (sp?), where they can actually construct new faces from parts of other faces or change one face to another (as in the Michael Jackson "Black or White" video), you know that computers can do many tricks with video that were formerly impossible. Want to shoot a scene of an old city that's supposed to have been filmed before the turn of the century, but there's some nasty old telephone cables strung across the scene that spoil the effect? No problem, just use a computer to "erase" the wires and poles from the scene! And now you say that you can do voice substitution on a phoneme for phoneme basis ... wonder when the day will come when we see a talking head on the screen that is totally computer generated and virtually indistinguishable from the real thing! And just ignore the man behind the curtain ...

The Microcom Microport 1042 is described above. They have a newer model the Microport 4232bis which supports v.32bis & v.42bis. Its serial prt speed is limited to 38.4kbps though. I have used it consistently at 9600 connect (with throughput of approaching 38kbps) over cellular. I have not been able to make reliable connections at 14.4 (I do get a normal mode connect but the handshake fails to make an error correction protocol, and noise is too high to be useful). Making consistent 9600 connections over cellular is not the norm, but it is possible. Most of my experience is in good cell locations I believe the cellular switch is Ericson (sold through AT&T?) My experience has been best with an NEC p300 w/ NEC 1202 smart interface. (ie. 600 milliwatt). This has been a better performer than a Motorola bag phone (ie. 3 watt) w/ internal smart data interface. My application is X windows under DOS remotely accessing Sun servers. Both Microcom modems use MNP 10, designed for cellular connection, but also good for bad terrestrial links. MNP 10 includes dynamic speed adjust, dynamic packet size adjust and dynamic gain. With dynamic gain on I can hold the cellular connection at higher speeds under adverse conditions (eg. taking the antenna off and shorting the antenna connection to introduce noise). PS: I don't know if the P-30 pinout question has been answered but the phone is basically identical to the old Radio Shack handheld (model number forgotten 2001?) and Radio Shack will sell you the tech manual for that phone.

No component failure can take down more than one line; most just reduce the capacity of the exchange by one call. Step-by-step switches are true distributed systems.

The 'cluck' after each digit was the selector "selecting" the next switch in the train. The Strowger switches had two motions: vertical and rotary (XY offices had vertical and horizontal). Each click of the dial sent the center rod of the switch up one notch. When the dial pulsing stopped, a relay with a capacitor across it (to make it slow-acting) would start the switch in a rotary motion, sweeping the contact arm around a set of contacts that were connected to the available subsequent switches of that level. The stepper solenoid would pull in and release as fast as it could until an idle set of contact was found. This gave the characteristic "thrruummp" after each digit was dialed. However the last two digits were handled on the same Strowger unit. The sixth digit would step the vertical rod to the proper lever and the seventh digit would rotate the arm until it contacted the called party's contacts. Since there was no "automatic" selection in the rotary plane, there was no "thrruummp". > One feature of these old direct-control step switches was that (when > they worked) they appeared to the sub to be almost as fast as > intra-office calling on a modern ESS. Intra-office call completion on a SXS was FASTER than any ESS switch. The slight pause was the "slow-acting" relay described above to ensure that the dial had actually stopped at that number. Otherwise, everyone's phone on that final switch might jingle as the last digit was dialed! The intra-office SXS call actually completed faster than on any common control switch past or present. It was not an illusion. Hell, my old #5 crossbar switch completed intra-office calls faster than the "new and improved" #5 ESS does now! (The 1/1AESS beats everything other than SXS for speed of intra-office call completion speed!) > Dial the last digit and !BANG! > ring or busy, even when calling inter-office to another direct-control > step system. Of course.

GTE use to do this on a large scale. It did enable them to do a lot of things without having to upgrade to more sophisticated equipment. In many cases this setup allowed expeditious implementation of Touch Tone dialing. The sender could be adapted to receive the DTMF and then "direct" the steppers accordingly. John Higdon | P. O.

TCAP stands for > Transaction Capabilities Protocol, and is used primarily in telephony. > Any pointers to documents, code (if available) would be appreciated. I had a long write-up I sent to an e-mail requester, but can't seem to find it. TCAP is an Application layer protocol, but the full series of Recommendations/requirements specify what is called the SS7 Transaction Capabilities (TC). This is basically TCAP plus the underlying Presentation, Session and Transport layer. These last three layers are called the Application Service Part (ASP) in SS7. Since current TCAP-using services all assume SS7 SCCP as a Network layer (connectionless, either Class 0 or 1) and explicitly state there are no required ASP services, the distinction between TC and TCAP is blurry. Unfortunately, it looks like SCCP will have to start supporting sequencing, segmentation and reassembly for some "bloated" TCAP services, thus making it look more and more like a Transport layer (and part of the Network layer as well). End of lesson 1 ... The protocol itself is specified in: Recommendations Q.771 to Q.774 of the CCITT "Blue" books. (But this is only the International version ... USA uses a somewhat different version ...) ANSI T1.114.x series of recommendations (used to be ANSI Q.771-Q.774) (The official standard is continuously modified by periodic meetings of the T1S1.3 standards working group, primarily by the TCAP Sub-working Group. If you have more than a casual interest in ongoing TCAP issues, you should find or create a group member.) Bellcore re-publishes a snapshot of the MTP, SCCP, ISUP and TCAP recommendations in TR-NPL-000246 "BCR Specification of Signaling System Number 7", currently at Issue 2, Revision 1. Revision 2 is due out in December. Expect it to cost about $500 -- and I don't believe they will break out the TCAP part (about 15%) as a separate (cheaper) document. I have also mis-placed by ordering info. for ANSI T1 standards, but maybe someone else can supply it. Lesson 2 ... TCAP is now described in ASN.1 terms in Appendicies that are semi-formally part of the standards. It is based on X.409 encoding and X.410 Section 2 (Remote Operations). So an understanding of ROSE and associated concepts is very helpful, since none of the Recommendations are Tutorials on the protocol. In fact, they are there is effort ongoing to more closely align TCAP with ROSE, but the older version of the standard was a confused merger of X.410 and TCAP "enhancements" needed to make the protocol useful in applications not supported by the typical Query/Response model. The language of X.410 and ROSE has evolved in the ten years or so that TCAP has been "in process". These changes and others account for major terminology differences between the ANSI T1.114-1988 and -1990 standards.

I pointed out that there would be many ways to defeat this, and postulated that said criminal could set up call forwarding on his home phone so that when he called into the computer from wherever in the world he was, the Caller-ID would show the number of his home phone. Several readers of the Digest took the time and trouble to point out that Caller-ID could NOT be defeated in this way, since SS7 (required to support Caller-ID) would also forward the number of the actual originator of the call for Caller-ID purposes when call forwarding a call. However, some also suggested other ways that the system could be defeated. Two of the most popular suggestions were these: 1) Get three-way calling on the line and get a relative or hire a neighborhood kid to set up a three-way call at the proper time. This would show the criminal's home phone number as the originating number, 2) Get one of those hardware call-forwarding devices that requires two phone lines. Call in on your "second" phone line, have the device dial the parole office voice recognition system on your primary line. You talk to the computer from anywhere, and if your "second" line is unlisted, few other people would try to call you and get the voice recognition system instead. Another option that would work is an "off-premises extension" of the first line run to some other location (such as the criminal's "office"). My whole point was to show that this type of system COULD be defeated by anyone who really wanted to do so. It might well be an adequate method of punishment for someone convicted of having too many parking tickets, but I certainly would not care to see it used on anyone convicted of a violent crime, or any felony. It's just too easy to defeat by anyone who really wants to do so. It was just unfortunate that I chose call forwarding as an example of a way that this system could be defeated. Of all the methods I could have suggested, that is the one that apparently will NOT work. Thanks to all who took the trouble to netmail me on this. I now know a little bit more about how the telephone system works!

There was a time a while back during a city wide rationalization of digital signaling when it took MANY long seconds to pulse dial the local digital exchanges on its interoffice trunks.

Well, I got a hint in a surprising way myself ... a year ago I was on the 'fone to the business office about ordering a long-distance plan or something, and was making an enquiry if BOTH of my numbers would be covered under one plan/one-fee since I only get one bill printed. They said, "Sorry, it cannot be done with Ident-a-call." I say, "What Ident-a-call? ... I have two physical lines ..." It turns out their database had a typo that I had Ident-a-call for two numbers rather than two physical numbers. I went on to say "This exchange isn't even capable of it!" They went "Mumble, maybe, well, yea, mumble, your file has been fixed, and yes the plan will cover both numbers." When I was a kid I remember this exchange (whole new building even, I lived about three blocks away) going into service. If you wanted the new-fangled touch-tone service you had to get a new number via this exchange. During the last few years if you wanted one of the new fangled services, you had to leave this exchange ... Over the years, various little quirks, and talking briefly to various Bell techies has led me to believe that at one time during its early "glory" years this was a model-exchange of new technology and new tricks were tested and installed -- if not advertised -- on it, but this is just a gut feeling. It would make sense given the profile of Waterloo being the home to a very technically literate population (two universities, electronics companies like Raytheon, insurance head offices, etc), and also a relatively high average household income. (Daddy, what's a slum?) (How many areas do you know where the citizens REGULARLY pay Ma Bell a couple dollar charge to do an operator interrupt on a busy line?? On some days it seems dollars mean nothing to the permanent residents, and that underlying feeling that "of course" everyone has call-waiting, and so "of course" something is unusual with a busy signal ... yuppie scum everywhere). Talk to the transient student population and you get quite another perspective however :-) :-) I swear that students must synchronize their watches and have a conspiricy to go off-hook at 11pm (cheap rate time) and try to grab long-distance/inter-office trunks; normal sentient switch behavior returns around 11:15pm :-) I would suspect even the most radical and generous capacity-planning couldn't compensate for this conspiricy of the residents of Suitcase-U.

See if these leads go to the bell. As for the DTMF, older phones don't have steering diodes to power the DTMF from the line. This requires polarity to be observed.

On April 1, 1992, Dr Paul Stern of Northern Telecom Inc. announced NT's bold new vision of the future. "We call it Strowger World" said Dr. Stern as he showed off the latest model of NT's new series of switches. "It goes along with our new quality and excellence thrust. You just can't get any more reliable than these babies. Before, with the software based switches, we had no ends of problems. With these, a drop of oil here, burnish a contact there, and they'll go for decades. If the power fails, the switch is ready to go as soon as power is restored. With our old software based switches, if the power failed, it took hours to get it running again. Now switch recovery is instantaneous!" When asked about NT's previous direction, FiberWorld, Dr. Stern replied, "Fiber World? Don't make me laugh. Where are the electrons going to go? Glass is an insulator! I admit that we were temporarily blinded by the insane promises of a few egg-headed visionaries, but the one, true, path became evident very shortly afterward. As our technical experts said at the time of that announcement -- 'Don't trust your ass to glass'." "It was time to go back to basics. Telephone switches should be made from real switches, not this electronic stuff where you can't see what is going on. 'Real switches for real people' is our new motto" he said proudly. After citing many of the advantages of the Strowger World switches -- among them the ability to do literal call tracing, Dr. Stern closed the session by inviting all Northern Telecom customers to "Come join us as we go step-by-step into the future." ------------ Winston Sorfleet Bell-Northern Research, Dept. 7D34 sorflet@bnr.ca Opinions expressed are purely personal and do not represent Northern Telecom or Bell-Northern Research in any way.

The award will be presented on Sunday, May 10, 1992, during the IEEE Honors Ceremony in Boston. Dr. Lars Ramqvist, Ericsson President and Chief Executive Officer, will accept the award for the company. Ericsson is the world's largest supplier worldwide of analog cellular radio systems, with more than 40 percent of market share. Founded in 1876, it is one of the world's leading manufacturers or telecommun- ications equipment and has been a success in merging radio and switching technology into effective, high capacity networks. "We have entered an era of 'personal communications,'" according to Dr. Ramqvist. "Cellular and wireless communications products allow us to use advanced information services in a convenient, natural way. Ericsson has been a pioneer in cellular and advanced wireless communications systems, applying advanced electrotechnology to solve important practical problems." With operations in over 100 countries, half of Ericsson's 70,000 employees work outside of Sweden. Ericsson is also known for its contributions to international telecommunications standards and specifications. Its concept of narrow band transmission has had a significant impact on specifications for the Pan-European Digital Mobile Telephone System (GSM) and the Telecommunications Industry of America (TIA). Further technical development by Ericsson formed the basis for Digital European Cordless Telephony (DECT) for wireless communications within buildings. The Institute of Electrical and Electronics Engineers, Inc. (IEEE) is the world's largest technical professional organization, with more than 320,000 members in over 145 countries.

They will be connected via a packet-switching line. People will call a phone number that is connected to system A. They will enter an access code, their phone number (or, if it's somewhere that does Caller-ID, of course we can skip this) and a phone number (located where system B is), and hang up. A will verify the information and pass it to system B over the packet-switching line. B will call the local phone number, and if the call goes thru (how does it know?) it says "please wait for a call to ", calls the phone number from which this all started, and connects the two. The result is that a person at A can call a person at B, but pay the rates from B to A (plus an additional charge, of course) rather than from A to B. The number of conversations supported at one time should be configurable. So can anyone recommend anything that we could buy, that would either do it all, or significant pieces of it? We would not mind having to do the software ourselves, but we really don't want to start building telephone interface circuitry, touch-tone/Caller-ID recognition, speech circuitry (and some way of knowing if the call was answered, I wouldn't even know how to start doing this unless call supervision is supported on side B and we cannot assume that) and getting it certified. Don't tell me about legal issues, because you'd have to know where A and B are to give accurate info, and the customer doesn't want this disclosed.

I'm sure you understand that the voice mail systems do not offer the interrupted dialtone to the client's line; they just ask the CO Switch to notify the client that a message is waiting. This interface is also used with Message Desk services. Whether the client has a message waiting lamp, the "interrupted dialtone" signal or some other method of notification (ISDN) is known only to the Switch. The voice mail or message desk service is also responsible for turning off the message waiting indication. The Voice Mail/Message Desk interface to the Switch, and the inter- switch signaling interface (SS7/TCAP) for turning on/off the indication are described in Bellcore's TR-NWT-000866 (Iss. 1, Jan. 1991) titled "ISDN Message Services Generic Requirements" ($75). In spite of the name, it discusses the inter-switch signaling for ISDN and non-ISDN clients, as well as ISDN and non-ISDN interfaces to the voice mail or message desk provider. In the TR, Bellcore calls the audible message waiting indication a "special interrupted dial tone", but I'm unsure what makes it "special". Frequencies are 350 + 440 Hz, at a (.1 second ON, .1 second OFF) rate, for at least 2.5 seconds, then steady ON. I haven't seen a statement specifying whether or not customer dialing must be accepted during the interrupted period, but that would seem to be reasonable. The tone and interruption rate are identical to the "Confirmation Tone" used to confirm Speed Calling recording or Call Forwarding activation/ deactivation -- but those only last .6 seconds. And 350 + 440 Hz at a steady rate is regular Dial Tone. [All tones are +/- 0.5% in more modern Switches, but could be different or less precise in some areas.] Hope this helps. Information on most switch tones are in TR-NPL-000275, "Notes on the BOC Intra-LATA Networks - 1986" (if you have it) or the replacement, SR-TSV-0002275, "BOC Notes on the LEC Networks - 1990", dated March 1991 ($395). ------------------------------ End of TELECOM Digest V12 #366 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa03970; 6 May 92 2:40 EDT Received: by delta.eecs.nwu.edu id AA22661 (5.65c/IDA-1.4.4 for telecomlist-outbound); Wed, 6 May 1992 00:46:52 -0500 Received: by delta.eecs.nwu.edu id AA26571 (5.65c/IDA-1.4.4 for telecomlist); Wed, 6 May 1992 00:46:43 -0500 Date: Wed, 6 May 1992 00:46:43 -0500 From: TELECOM Moderator Message-Id: <199205060546.AA26571@delta.eecs.nwu.edu> To: "\\telecom"@eecs.nwu.edu Subject: TELECOM Digest V12 #367 TELECOM Digest Wed, 6 May 92 00:46:44 CDT Volume 12 : Issue 367 Index To This Issue: Moderator: Patrick A.

McMillin) Subject: It's A Riot: Followup And then on Thursday, it got horrible. My boss called to tell me that second and third shifts had been cancelled, although I didn't get the message on my answering machine until the loudmouth pool players downstairs in my apartment complex said something about people shooting at the Ralph's grocery store across the street. THAT woke me up (I work graves these days ... yikes!). There were rumors that the Circuit City next door had been looted (it hadn't), and that rioters robbed the bank next to my girlfriend's work (they had). Also, looters had sacked the Hawthorne Mall not five miles up the street from where I live, and two miles away from the Hughes facility where I work. This was at 3:00 or so in the afternoon; I then made about five calls before GTE shut down dial tone to residential customers. Pay phones continued to work. According to news reports in the {Orange County Register} -- I hid out for a couple of days at my parents' house in Huntington Beach -- Pacific Bell claims that as few as 50% of all attempted calls were getting through in the 310 and 213 area codes at the height of the rioting. My girlfriend was able to get through to her parents in Arkansas, and strangely enough, they were able to call me, even though my girlfriend was unable to successfully call me directly from work. TELECOM Digest really isn't the place for editorializing, but I would like to make a few brief comments: * The verdict was wrong. There was nothing that Rodney King could have done that could justify the violence those policemen used to subdue him. I can only hope that the subsequent federal investigation comes to a more reasonable conclusion. * This Sunday's {Los Angeles Times} contains a very reasonable proposal for the creation of an independent prosecutor whose job is limited to trying cases involving police and other public officials. It has been tried successfully in Philadelphia, and needs to be used in the City of Angels. * Whites need to recognize the legitimate concerns of blacks that the judicial system has collapsed for them. Part of this problem is that Los Angeles is woefully underpoliced to begin with, which has lead to the cops' paramilitary stance, whereby they hope to frighten residents into lawfulness. It hasn't worked, nor will it. If, as Lincoln believed, governance flows from the people, then cooperation with the governed -- and therefore, the policed -- is crucial. We simply cannot afford to have cops out there who believe that black men are automatically suspects. * Blacks need to understand that attempts to sweep criminal activity under the rug of race won't do. Too many were the cries that Marion Berry's accusers were motivated by racial rather than legal or political issues. The ethnic exclusionists only worsen the situation with their creed, "It's a black thang -- you wouldn't understand." People of EVERY color -- white, black, brown, yellow -- were busy looting. We all saw it on CNN and the local news. Now, maybe, we ALL can start calling a criminal a criminal, regardless of what color his skin is. * Lastly, unless we do something constructive about the underclass in our cities, and by this I do not mean the big-spending giveaway programs that serve to feed bureaucrats at the expense of those they purportedly help, we will find ourselves in a few years taking bulldozers to entire neighborhoods and simply starting over. The redistributionists, for whom capitalism is a four-letter word, have already started to crawl onto the Times' editorial pages. Let us hope that their rancid ideas for state-run looting don't seal the fate of the urban poor. It's been a scary, scary week. The most awful thing, though, is that the blacks I've talked to say that this is just the beginning. I hope it is not true, but fear they are right. Robert L.

Traditionally, amateur radio is the alternative to the telephone in times of crisis, and hams have very elaborate organizations that can swing into action quickly. The Internet needs a plan for doing the same. Example: Every UCLA student probably wants to call home. How about having them report to the computer labs (or call the computer labs via internal un-disrupted telephone), where messages about their welfare could be sent by Internet to sites near their parents' homes, and delivered by telephone from there?

From my home modem in Long Beach (ac310) I dial our HDMS dial back security system in Cypress (ac714). I get a dial tone OK and an answer. I enter my username and password, hang up and wait for call-back. The call-back never came. I could dial out fine from within the riot zone, but the call-back which comes from the safe haven of Orange County had trouble. Why is that? The other problem was with LD.

Calling South-Central a part of town in the downtown area is preposterous and reflects, I suspect, a Westside yuppie's blinders to the rest of the city. South-Central starts at Pico -- which is the equivalent of 13th street -- and runs down to El Segundo Blvd. -- which is about 127th. That is 114 blocks, which is no closer to Downtown than Beverly Hills.

I look out (with a 210 degree view) over the whole of LA, Westwood through Beverly Hills to Hollywood to Downtown to the Eastside to South Central and down to Long Beach. My field of view was a mass of smoke and fires, visible in Hollywood, out on La Cienega, all across the city. There were, at any one time on Thursday afternoon, probably 30 fires going at once and many more burned out and smouldering. > According to my telco sources, almost all of the problems were caused > by overloading.

That's the key phrase "West Los Angeles". It's served by GTE, whose equipment was probably completely un-impacted by 911 calls.

I'll agree to that! Gates' ego could not admit that he wasn't prepared for what happened and that he couldn't handle it. So he stalled. He wouldn't even talk to the Mayor. If they hadn't run into each other at the command post, they never would have talked. Here is an unconfirmed bit of information which I think is extremely reliable: Before it all started, LAPD at the corner of Normandie and Manchester were taunting some gangbangers about the verdict. The crowd got ugly, the LAPD called for backup. Five cars came, they shagged out of there, leaving the poor random citizens who subsequently came through the intersection to suffer the wrath of an incensed crowd. Trucker Reginald Denny's beating on TV was one of the results. I called the LAPD Wednesday night when I heard distant shouts, looked out my view windows and saw, with binoculars, a crowd looting a swapmeet building. The LAPD showed up [after 20 minutes] in two cars, four officers total, told everyone to drop the stuff and go home, waited until the looters had left and split. The looters came back. I called again. This time they came back with eight cars, did the same thing. One tidbit overheard via the police megaphone and the wonders of uphill sound transmission (I live nearly 1000 feet away and 16 stories above the area in question): "Put down the merchandise. Put it down. Look man, I've got your license number [all these thieves had cars and were loading]. Do you want me to come to your house? Come on Homie, don't be a fool. Put it down." Homeboy put it down, got in his car, drove away. Absolutely no arrests were made, in either arrival. The LAPD. As they say so well in Iowa "worthless as teats on a boar hog." I hate to be a Monday morning quarterback, but if they had handcuffed a couple of looters near the entrance and left just one Black-and-White on location, I'll bet a lot less looting would have taken place. It was the clear understanding that no one was going to get arrested that encouraged the looters to get everything they could. ------------------------------ End of TELECOM Digest V12 #367 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa06420; 6 May 92 3:40 EDT Received: by delta.eecs.nwu.edu id AA29482 (5.65c/IDA-1.4.4 for telecomlist-outbound); Wed, 6 May 1992 01:47:02 -0500 Received: by delta.eecs.nwu.edu id AA20453 (5.65c/IDA-1.4.4 for telecomlist); Wed, 6 May 1992 01:46:47 -0500 Date: Wed, 6 May 1992 01:46:47 -0500 From: TELECOM Moderator Message-Id: <199205060646.AA20453@delta.eecs.nwu.edu> To: "\\telecom"@eecs.nwu.edu Subject: TELECOM Digest V12 #368 TELECOM Digest Wed, 6 May 92 01:46:45 CDT Volume 12 : Issue 368 Index To This Issue: Moderator: Patrick A.

I am a photojournalism student at a local college, and I drove down to the most affected areas yesterday (Saturday). While we got some extremely poisonous glares (we're both white), everyone we talked to was friendly and open.

The city was truely on fire Thursday and Friday, with over 40 people dead from the rits and over 3000 fires lit. I must emphasize, however, that it is safe again in L.A. (as much as it ever was ) and that most of the city was not affected in any material way by the fires or civil unrest. [Moderator's Note: Not affected in any material way? The hell you say!

It is now going into 'open' beta testing. To send mail to an America Online, Promenade or PC-Link user you need to know the user's screen name. The only way to get a user's screen name is to contact them by other means (ie there is no name server). Once you know a user's screen name remove any spaces, make it lower case, and append @aol.com. For example to send to the screen name A User you would address your mail to auser@aol.com. To send mail from America Online to the Internet you simply put the Internet address in the To: field on the regular mail form. In a previous post the question was posed as to whether or not there are 'special' gateways for Compuserve, MCI Mail etc. The answer is no, there are not. For some of the more popular services abbreviations have been created; for example to send to a Compuserve user you can use the address 123.4567@cis. Additional information can be found on America Online by using the keyword InetBeta. There is no additional charge for using the Internet mail gateway. Mail is limited to around 27k bytes in both directions. If you notice any problems with this gateway please send mail to inetbeta1@aol.com from the Internet or inetbeta from America Online.

See also the reply which follows. Original From: Max Moen To: All Subject: Ma Bell & The Flood [forwarded by RelayNet's PHONES conference] MA BELL AND THE CHICAGO FLOOD Since I work in the Chicago central office that serves the area flooded out in our fair city's recent tunnel disaster I thought some of you might be interested in hearing how Ma Bell fared in this crisis. If you could see, me you'd see an ear to ear grin. The Windy city is about as flat as a pool table, but there are a handful of well known ridges that were once ancient shorelines for what geologists call Lake Chicago (at one time the communities of Summit and Blue Island were the only areas of Cook County above what is now called Lake Michigan). Chicago was slough and wetlands area until the 1880's when George Pullman proposed raising the city up on at least six feet of topsoil. Actually, Pullman meant to level the city off, so to speak, but the City Council didn't understand and passed a law that said six feet from the present level. For that reason we still have those few ridges left (they're just six feet higher and we still get flooding, just not as much) and as fate would have it, the Franklin Central Office is about 3/4's of the way up one of them. We were like Moses in the Red Sea, floods to the east of us, floods to the west of us, but even our sewer didn't fill up, the muck just flowed past. They didn't even cut off our electricity, the boundary was the alley behind us! If they had, of course, our diesels could have handled the load until the fuel ran out. For the first few days we ran the diesels and powered the equipment from them just in case, but the building remained on Edison power and we never even shut off the elevator (phew). If you thought Hinsdale was a big deal, that's a two story building; Franklin is 18 stories, it services almost the entire Loop and everyone from the FAA to Network Television has circuits going through there. Actually, the likelihood of a flood taking out an Illinois Bell central office is pretty slim. The only time it did happen was because a once in a hundred year flood hit while the office was under construction and the emergency systems were shut down (i.e. someone really screwed up). BTW, we had two "once in a hundred years" floods in a row; the previous one was 45 years ago. Each C.O. has the power plant and batteries located at the highest point, if it's a level basement, the plant is located on an elevated platform. Each C.O. is provided with a special high volume flush valve that is said to pump thousands of gallons a second from a basement. Of course, they weren't expecting the whole Chicago River to show up as was this case. At one point the Board of Trade building was pumping 2500 gallons a minute and still saw the water level rising. Our only real involvement has been in relocating the telephone services of those companies that have temporarily moved. The only real problem we had there is that one of our Vice Presidents promised all sorts of people all sorts of extreme due dates, but nobody really called out the troops over the weekend to do all the necessary rewiring. It was pretty frantic Monday morning, but we seem to have met the commitments.

So, off came the roof; in came the big black cloud which parked itself over the building and dumped gallons of water onto the building. It rained as hard over several banks of line finders, connectors, E6 repeaters and the MDF as it did outside the building. One CO man was soaked from head to toe as he tried to pull plastic sheets over the cable runways. Waste of time, as it was all in vain. The SP-1 office was miraculously spared. The old stepper was eventually replaced with a DMS100 and the SP-1 and the DMS100 have both since been replaced with a DMS100 Supernode. Next exciting time I had was in the Killarney CO where the roof was removed to put a second floor onto the building to house the SP-1 addition to handle the growth in the area. Same thing happened there. We had hair dryers and pressure cleaning fans running in there for a week to try and dry things out. Green grunge on selector banks for months afterwards, along with all sorts of noise trouble reports. Both the old stepper and the SP-1 followed the same path as the Kingsland equipment. My final experience with water was when a watermain burst just outside the Calgary Westin hotel. Flooded the hotel's basement and the NEC NA4-09 crossbar PABX that was in it. There it sat in four feet of water. No-one wanted to wade over to the rectifiers to shut them off and the battery string was just gurgling away! The 4-09 was a write-off and was replaced with a GTD-1000. The only saving grace was that it happened a couple of days before Christmas and the hotel was for all intents and purposes empty. Anyway, I don't know what was worse ... the NA4-09 or the GTD. Eventually the GTD got flooded out too (leaky toilet on the floor above) and was replaced with a nice Northern Sl-1.

And says it essentially no longer detects "hangup" signals from the CO when wired behind the Panasonic. I'm guessing the Panasonic is a small PBX or hybrid key system? (I have no clue what a EMSS is.) I would assume that very few PBX's pass the flash or polarity reversal from the CO on to the individual extension circuits. Personally, I'd put it "in front" of the PBX instead of "behind" it, connecting directly to the CO line. If you have several lines or want to call it from a PBX extension (to retrieve messages using an in-house phone, for example), a two-line adapter device might work.

In about the last seven places I have lived I have added a second line ... first because I had a roommate and we wanted our own lines, then later because of my computer modem use. In the early instances they just ran another line from the nearest phone pole (evidently the existing wiring did not have two pairs.) Then I moved into a house pre-wired for two lines (from the previous occupant) but was told due to rapid expansion in the area I could not only not get two lines, but couldn't even get one line for a few weeks! Actually, a few days later the phone company had a technician spend hours moving wires around and somehow came up with two free pairs (or so they told me.) Later, I was living on a dead-end street and was told no pairs were available or would ever be available, so they piggy-backed a second line with a frequency shifter that put my call on top of the existing line. It had a little rechargable battery that trickle charged from the line ... if I made hours of calls in a single day the battery would run down to the point I could not use the line. Then I moved to Oakland, California and was cheered up over the prospect of getting two real lines again, partially because many of my two-line phones features, such as the memory and line use indicator did not work on the funny line. Guess what -- they gave me a real line and a frequency multiplexed line. Even then they had to run a line from down the street about one hundred yards. Perhaps others can use this 'old' but useful technology to work around a limit of wires. As more and more people add fax machines and modems, the line shortage may grow instead of shrinking!

I'm not giving up yet. According to a tariff named A4 (don't ask me why) the flat rate of $1035 dollars is a valid amount for any and all situations where the street needs to be dug up. This comes from the ACC which sets or qualifies these prices here in Arizona. I am going to challenge the charge. There was a device called SLC-1, aka slick-1 which used a battery in the central office and one at the home externally which allowed a second signal to be carried over the same voice line. These are being pulled due to their inability to work with such things as call waiting, voice messaging etc. In addition, there is a distance limitation of approximatly one mile on this device from the central office to the home. I come in at the two mile mark. All of this information comes to me via the USWEST engineer for my area. If anyone has opinions on this which may differ or add more information, I'm open to suggestions. I had one last idea, that being, see if I could get a bordering neighbor who has only one line in use to let me use their free line and bury it all the way to my house. The USWEST rep said this could be a possibility and he is looking into it. Thanks to all who responded on the first round of this fun with phones. Scott Colbath Stratus Computer Phoenix, Az. (602)852-3106 Internet: scott_colbath@az.stratus.com [Moderator's Note: If a bordering neighbor has an unused pair, it is probably already multipled on the pole behind your house and could be brought in normally. Anyway, if there is *at least one* spare pair in the vicinity which is multipled to the pole or drop near you, I can't see how telco can hold you responsible for the costs of street excavation. I don't think they can hold out the pair from you merely in order to service a possible new (single line) subscriber who might come along later and be angry that *they* had to pay the big $$ to get a line installed. Are you *sure* no more pairs are available or that just what telco is saying to get a handout to help with the cost of a new cable in the near future?

Here is the scoop directly from the rates database. (GO MAILCHARGES) COMPUSERVE MAIL RATES FOR STANDARD PRICING PLAN Your CompuServe membership of $7.95 per month includes an electronic mail allowance of $9.00. With this allowance you can send up to the equivalent of 60 three page messages per month with no additional charge. Note: Each 2,500 characters is about one double-spaced page.) This monthly allowance applies to both ASCII and binary messages. Your remaining message allowance expires at the end of each month. **The following is included in your monthly allowance: Send Mail (per message):* first 7500 characters $ .15 additional 2500 characters $ .05 Receipt Requested: per recipient $ .15 Read/Download Internet Messages:** first 7500 characters $ .15 additional 2500 characters $ .05 * The charge per message is multiplied by the number of recipients you have chosen to receive your message. Surcharged messages, such a Congressgrams, fax, telex, and postal are not included in the $9.00 monthly allowance. ** If Internet messages are deleted without reading or automatically deleted by the system after 30 days, no charges are incurred.

I don't claim to know all the pros and cons of other possible arrangements, but our arangement is as follows. We have two lines, a two line answering machine and a two line phone. One line is set to hunt to the other; I couldn't get New England Telephone to make both hunt to each other. (As has been mentioned here before, hunting doesn't cost anything, neither for the initial installation nor as a monthly fee.) With this arrangement, I make outgoing calls on the line that hunts; that way any incoming calls can be picked up by the answering machine. (By the way, I despise call waiting and don't have it.) We give out one number to friends and family (no connection with MCI) and give the other to acquaintances and those of lesser relation. Our two line answering machine is the AT&T 1332. It works well enough and does allow calling in and replaying messages and a bunch of other functions. I wish it stored the announcements (it can handle four of them) in NVRAM instead of on tape; it does a whole lot of clicking and tape motion every time one of the phone lines rings. If you listen to your messages but don't rewind them, the "new messages" light keeps blinking -- a big misfeature in my book. It also won't record TDD messages (though many other answering machines won't either). A good argument could be made for buying two separate machines with more/better features and/or fewer bugs, but the convenience of having all messages on one tape (it identifies which line each message came in on) shouldn't be neglected. I don't know why someone would recommend two phones instead of a two line phone; I really like ours. One thing you can't get from separate phones is that it lets you join the two lines for a conference call; I never use that feature, but it might be handy for others.

Wednesday, April 22, 1992 -- Noon EDT AT&T today introduced a new service for the residents of China that makes calling relatives and friends in the U.S. easy, affordable and reliable. The new service -- AT&T USADirect Service In-Chinese -- allows callers to place calls to the U.S. with the assistance of a Chinese-speaking AT&T operator located in the U.S. Calls can be made from virtually any phone, including home phones, calling centers and other public telephones. To access the service, a caller only needs to dial 10810. An AT&T operator in the U.S. who speaks Mandarin Chinese will answer, take the phone number and name of the person called, and place the call. Calls will be billed to the person accepting the call. AT&T today also introduced a similar service for the residents of Poland -- AT&T USADirect Service In-Polish -- which allows customers to place calls to the U.S. with the assistance of a Polish-speaking AT&T operator located in the U.S. Calls can be made from any phone in Poland that has international direct-dial capability. To access the service, a caller must dial 0, wait for a second dial tone, and then dial the number 010-480-0112. From some large businesses and hotels in Warsaw, a customer simply dials 010-480-0112. An AT&T operator in the U.S. who speaks Polish will answer, take the phone number and name of the person being called, and place the call. Calls will be billed to the person accepting the call. With today's announcements, AT&T USADirect Service In-Language is being offered in 15 countries and three languages: Spanish, Polish and Chinese.

To this end, there are a number of lines in labs (somewhere on the order of a dozen) and a number of lines into homes of people involved with the project. In addition, there are a few Frame Relay lines. Work has focused on expanding the campus network by sending IP over ISDN, connecting to a Frame relay network via ISDN, and exploring the feasibility of sending video over ISDN/Frame Relay. The project is expected to continue at least through next year. While this may be an isolated case, there is at least some interest in ISDN as a generally available service within Pacific Bell.

Beleive me they are not dweebs, and they are not harmless. By asking for the checking account numbers of people who call them, they were able, in at least one case I know of, to withdraw money from someone's account without authorization. This type of check fraud, which involves printing fake demand drafts, has become a major problem over the last two years. Also, the operators of 312-296-9000 appear to have violated an Indiana law that requires auto-dailers to begin messages with information describing who the telemarketers are and what they are selling. The name "MSC Associates" does not sound familiar to me. Here in Indiana, they have identified themselves as "American Consumer Services." One victim in Bloomington, IN, had money siphoned off his checking account shortly after he called ACS back.

Today, each organization is calling public attention to the potential for abuse of toll-free numbers and to describe the steps they are taking to protect consumers who call 800 numbers. CA is working closely with the carriers to develop changes in tariffs that would address the problem. According to CA Director Ken McEldowney, "The problem we are fighting is the use of 800 numbers to bill for 900-type information services. There have never been charges for making calls to 800 numbers. However, in the past month we have heard of phone bills or look-alike phone bills for information received over the phone. "This is the type of service for which "900" numbers were created. But with increased regulation of 900 numbers, some information providers are switching to 800 numbers, taking advantage of the fact that people assume they won't be charged for calling 900 numbers. Currently, there are no effective regulations to prevent the misuse of 800 numbers for billing of information services. This puts consumer confidence in the free 800 call in jeopardy. Long distance companies are also concerned about misuse of 800 services. AT&T and Sprint have discussed new tariff language with the Federal Communications Commission (FCC) to prevent use of 800 numbers to bill for information received over the phone, except in cases where there is a previous relationship between the caller and the service, or the caller agrees to be billed on a credit or charge card. To illustrate his concerns, McEldowney described three 800- number services that people had complained about to Consumer Action: - One was a postcard solicitation that had previously used a 900 number. It urged people to call a toll-free 800 number to learn the prize they had won in a "sweepstakes." Although callers were first told there was no charge for the call, they were later told that, for a fee, they could press a number on their phones to learn their prize. Many of those who did, subsequently received a bill containing a $10 charge listed next to the 800 number they had dialed. - Another service promised adult conversation at $4.95 a minute. Students at some midwestern universities and colleges called the service at an 800 number from campus phones. Four months later, the schools received charges for the calls on their phone bills. In some cases, the institutions did not know who made the calls: in others, callers had already left the institution. - The third service provided psychic information over an 800 line, for $120. Callers were to make appointment to speak to a psychic counselor, and to indicate whether they wanted to pay through their phone bill or through a credit card. "We are especially concerned about any charges that appear on a phone bill," said McEldowney, "because in some states people can lose phone service if they don't pay such bills." He stressed that bills for information received on 800 numbers are not subject to the same type of consumer protections as are calls to 900 numbers or charges billed to a credit card. "Billing for information services on 800 numbers also negates the protection offered by the blocking of 900 numbers. People who think that 900 blocking protects them from unauthorized charges will be vulnerable to similar bills for information services using 800 numbers." CA wants Congress to consider legislation to prevent abuse of 800 numbers. Legislation should codify the tariff changes proposed to the FCC by the long distance companies, said McEldowney.

Telephone Sales People 2. Telephone Sales Computers 3. Hanger-Uppers 4. Wrong Numbers 5. Bill Collectors 6. Late Night Callers 7. Family/Friends/Children who make 1-900, 976, and long distance calls 8. Radio Stations 9. And anyone/anything else that uses/abuses my phone I've decided at last to build the ultimate call sceening box and I'd like your help and input. These are the features I'd like to see: 1. My phone never rings for the groups 1-6. Depending if I'm annoyed with them I'll either shunt them off to an answering machine or simply hang them up (for the cronic callers). No hint of an DTMF ID in the answering machine message. My reject list can include all numbers from an exchange or an area code. 2. Automatic pass through without DTMF ID for certain numbers (i.e. family, friends, work, and the like). Folks who want to reach you but are not at a known phone number have to give a DTMF ID during the answering machine message which rings and connects your phone. Again whole exchanges/area codes can be included. 3. Any phone number that calls you is automatically logged no matter how the caller is eventually handled. 4. Automatic/Repeat redial. 5. Speed dialing. 6. Must dial a code for long distance, 976 and 1-900 numbers. Date, time and length of call are automatically logged for any toll calls. 7. Both a console interface (via keyboard and display) and phone interface (via DTMF and speech synthesis) are required to allow for easy home use and remote use via the phone. Over the years I've seen bits and pieces of the functionality I want: 1. Steve Ciacia (of Circuit Cellar Ink and formerly of BYTE) has had several articles on manipulating the phone. The last article he wrote on phones used a voice synthesizer and a DTMF interface to give info about his home control system. 2. An article in {Radio-Electronics} (I think) showed how to build a 976/1-900 eliminator. 3. Local phone companies have a plethora of custom calling services as you well know. Unfortunately they can double your monthly phone bill and still not give you exactly what you want. 4. And of course the Caller-ID boxes and other phone screeners on the market. So the real question is how to pull all this together without spending an arm and three legs. Let's see what parts are needed: 1. The only custom calling service actually needed in Caller-ID. It'll provide the phone number and the screener can use the info to route the call. The screener can emulate the speed dialing, repeat and redialing, callback and the like. I know I can get these from the phone company but the monthly charges can and do add up. 2. A Part 68 DAA, an SC1211 caller ID detector, and a DTMF transceiver (Silicon Systems used to make one) should be enough to interface everything to the phone line. 3. B.G. Micro sells a text to speech synthesis board that takes speech over a serial line and speaks it. $70 isn't too too much for that. 4. A microcontroller with a serial port (for the text to speech board) and I/O ports to interface to the DAA, SC1211, DTMF transceiver, LCD display (Timeline has a nice 32x4 LCD display with ASCII interface for $20), and keyboard (PC keyboard or maybe just another DTMF matrix). Any of the 8051/68HC11/683XX families should do fine. 5. Battery Backed RAM and an EPROM for memory. Also a real time clock (maybe even a no slot clock from Dallas Semi). 6. Parts to switch the phone line to different destinations. Probably a few relays should do the trick. [actually I have most of 2-5 in my junk box. I need the DAA, DTMF xceiver, and the LCD display.] So I figure for $100 to $150 I can get a box that will make my telephone work the way I want it. I just need some serious software which is my specialty. I know that a PC can do much of this stuff but PCs in general are too big and/or too expensive for this dedicated task. My basic hookup plan is to put the screener box between the internal phone line and the external phone line at the network interface. The screener must monitor both lines. I figure it to have the following basic responses: 1. Ring on outside line: a. Get caller ID number after 1st ring b. Log number and Lookup number in phone number database c. If automatic accept then connect internal and external lines. d. If automatic reject then pick up external line then hang up. e. If neither c nor d the connect external line to answering machine and listen for DTMF. If valid code given then turn off answering machine and goto c (screener must give artificial ring to internal line). 2. Off hook on internal line. a. simulate dial tone. b. if detect special key then do special function on external line. Special functions include speed dialing, redial, long distance access, etc. When ring detected on outside line connect internal and external lines. If toll call then log date, time and length of call. c. if normal key then connect internal and external lines. Listen to DTMF tones. if 976 or 1-900 dialed then disconnect internal and external lines. Now I am unfortunately a computer dude and not a telephone engineer. So I have some questions: 1. How hard is it to simulate dial tones, ringing etc? How difficult is it to detect off hook? I'd have to do all the above for the internal phone line. 2. How difficult is it just to do ring detection? Is it legal to use an optoisolated circuit to do ring detection without a DAA? 3. Is it possible to use audio switchers to route the phone lines? Is there any other reliable method other than relays to accomplish this? 4. Does anyone know of a easy way to electronically record speech without resorting to a codec? I understand that intelligible speech can be encoded in 8-12Kbits a second. 64K/second is a litle to costly in terms of memory bandwidth. I'm hoping to put an all electronic answering machine in the screener box. 5. Does anyone know where to get an inexpensive DAA and DTMF Xceiver? I believe this box is doable and I for one can find many uses for it. If anyone has any suggestions on how to do/improve this idea I'd sure like to hear from you.

Turner Subject: Telephony and the Chicago Flood There have been a pair of interesting articles in {Telephony} (Apr.20 and Apr 27) about the Chicago flood. I thought I'd post a summary of what they said about the various carriers. Remember this is from {Telephony}, so take it with a grain of sand: Illinois Bell They were pretty well prepared with two EOC's, one in town, and another in the suburbs. None of their CO's lost power, none of their cable was installed in the tunnel, and the only problem they had was with nine buildings where flooded basements shorted out cable terminations. Most of Illinois Bells involvment was to help bussinesses redirrect calls out of the loop. They call forwarded 2000 lines and installed 16 ISDN consoles [BRI?], 12 T1s, 2 T3s, 4k Centrex lines and 4K temp. cable pairs. Teleport Their biggest problem was a fiber cable going into the Chicago Board of Trade Building. It passed through conduit that was allowing water into the basement, and officals wanted to cut it to cap the conduit. MFS Had to run on emergency power for 12 hours as power was being rerouted before underwater transformers could fail. They also lost 100k dollars of equipiment in the LaSalle St. building. Their CEO said they were worried about all the holes being drilled all over the city, either for monitoring, or for pumping. Another article said the fiber of at least one carrier was encassed in a seamless aluminum jacket that would protect it as long as the tunnels were not drained too fast.

"Service Makes It Harder To Override Caller ID" By Anthony Ramirez In the cold war between those who find Caller ID appealing and those who find it appalling, Bell Atlantic is marketing a service that will disconnect callers who try to mask their telephone numbers using another service, also available from the Bell Atlantic Corporation. A unit of the Philadelphia-based regional phone company, the Cheasapeake and Potomac Phone Company of Virginia, said the new service, known as Anonymous Call Rejection, might be so attractive that even people who do not have Caller ID devices may want to subscribe. "It is a deterrent to people who block their calls and who could be a pain in the neck," said Susan J. Rubin, Bell Atlantic's product manager for Caller ID. Often marketed as a deterrent to obscene and prank callers, Caller ID displays the telephone number of of incoming callers on a small device beside the telephone. Some consumer advocates, however, regard Caller ID as an invasion of privacy and a way for businesses to record numbers for commercial purposes. Thus, many states require Bell Atlantic and other carriers to allow callers to block their numbers. This, of course, led inevitably to anti-anti-Caller ID. Someone with anti-Caller ID calling a household with Anonymous Call Rejection will now be told that if they want to complete their calls, they must redial without blocking their number. Centel, US West and Bell South either offer or plan to offer similar services. The Bell Atlantic service became available last Friday in Northern Virginia. Virginia callers cannot block telephone numbers, but customers in nearby Maryland and Washington can. The company plans to extend anti-anti-Caller ID to those areas and Delaware between now and September. ------------------------------ From: David Lesher Subject: CLID Block Block Date: Tue, 5 May 92 21:07:46 EDT Reply-To: wb8foz@mthvax.cs.miami.edu (David Lesher) Organization: NRK Clinic for habitual NetNews abusers - Lakeside Terrace See & Pee Telco is looking for {tri-}PSC approval to offer blocking of CNID blocked calls.

Responding to consumer group criticisms of electronic telephone call-screening services, the Canadian Radio-television and Telecommunications Commission has ordered five phone companies under its jurisdiction to eliminate the 75-cent-a-call fee to block the call display service by June 1. The CRTC also ordered the phone companies to change the rate for its call trace security service from a flat monthly fee to a pay-as-you-use charge. Both call display and call trace are part of a portfolio of specialized electronic consumer services called call management service. The call display service displays an incoming caller's phone number on an electronic screen attached to a phone line or built into the latest generation of telephone sets. Call trace allows a subscriber who has received obscene or annoying phone calls to electronically send a caller's phone number to the phone company's security department immediately. The call management portfolio also includes call return to automatically redial the previous local caller and call screen to block calls from up to 12 phone numbers. The services are offered by: Bell Canada, a unit Of Montreal-based BCE Inc.; British Columbia Telephone Co. of Burnaby, B.C.; and the four Atlantic telephone utilities. Subscribers can lease as many of the services in the portfolio as they choose: The first costs $4.75 a month and each additional option costs $2.25. Bell Canada has more than 300,000 customers using various call management services in six cities, a company spokeswoman said. B.C. Tel has 30,000 customers in Victoria and the lower mainland using the services. However, the CRTC has been assailed by numerous consumer and social welfare agencies since it approved the call management services two years ago because of its decision to allow the phone companies to charge 75 cents each time a customer blocked the transmission of a phone number by dialling through an operator or punching in a special code. Although the commission subsequently waived the fee for shelters and community agencies, CRTC chairman Keith Spicer argued at the time that the value of the call identification services to thwart annoying calls outweighed privacy concerns. Explaining the CRTC's change of heart to allow free identification- blocking to any subscriber who requests it, Mr. Spicer credited the input from several public interest groups. Customers with unlisted numbers, who already pay a premium to keep their numbers secret, were the most upset. "We now have much more information from the phone companies, as well, and data showing that new network features make it more convenient for the phone companies to block the release of numbers to protect subscribers' privacy," Mr. Spicer said in an interview. The CRTC also told the phone companies that the technology to trace an obscene call should supersede any request to block a caller's identity. Mr. Spicer believes widespread use of the call trace feature can preserve the benefits of call message services to thwart obscene callers while preserving individual privacy. "Taken together, we think both services have the potential to eliminate over 90 per cent of all obscene and annoying phone calls, " he said. The CRTC hopes to encourage wider use of the trace service by eliminating its monthly fee and ordering phone companies to file a pay-as-you-use fee for the service. Bell Canada spokeswoman Anna Di Gorgio said the company is pleased with the changes. The utility will immediately begin a rate study to determine the user fee for the call trace service in order to meet the June 1 filing deadline, she said. Bell Canada shelved its studies for pay-as-you-use basic local phone service, which it put forward in the mid-1980s, because of public opposition. However, Ms. Di Gorgio said the utility will likely analyze the response to the new call trace rate to determine if pay-for-use billing is a more attractive form of billing for optional services. Caller-identification services have been banned by a Pennsylvania judge in that state and California may do likewise because of privacy concerns. However, the Public Utilities Commission of Massachusetts recently issued a decision similar to the CRTC's latest ruling and told the New England Telephone Co. it could offer the caller-ID feature if it gave subscribers the option to block the release their numbers on outgoing calls.

BRT, a subsidary of BR, owns and operates an extensive telecoms network used mainly by BR. It boasts some 3000 route-km of installed fibre and over 14,000km of coppper coaxial cable. It presently carries traffic for Mercury, runs some private circuits (both voice and data) and supplies a national trunked Band III radio service. Now it is looking to co-operate with cable-TV suppliers to complete the local loop in some areas; another option for the final link to the home is using radio, from base stations on BR land, which, the company says, could cover almost all of the population using GSM or PCN radio standards. Since its launch as a seperate enterprise in September 1990, BRT has been looking for partners and sponsors for its expansion into the public market. It is still looking - and admits that the whole enterprise 'has taken us longer, it's been far more complicated, than we thought.' The hope now is that the licence, if granted, will help to convince potential partners by setting the conditions of BRT's entry into the market. BRT reckons to be roughly in the position where Mercury was two years ago, and says that Mercury has 'broken the ground' in international markets, making it easier for competitors to enter the market. We're getting there (BR's motto)?

But callers in the Portsmouth area are now in the front line of a telecommunications revolution as technology advances and companies offer increased competition. Established operator BT is facing a concerted challenge from Mercury and cable firm NYNEX as the battle for domestic and business customers along the South Coast intensifies. Nynex, an American-based company, is investing 100 million pounds in the solent region to provide cable television and telephone services by 1996. It won the local franchise after the Government ordered an end to the telephone duopoly of BT and Mercury. The project involves 218,000 homes. Workmen are laying 2,200km of fibre optic cables under roads and pavements. Mercury whose digitial network is being used by Nynex, boasts it is increasing its market share, converting thousands of customers in Hampshire and West Sussex and undercutting BT on prices. There is also a bullish mood at Nynex, which has established a local headquarters at Waterlooville and electronic nerve centre at Cosham. The company has other southern franchises for cable, including Sussex and Surrey. Domestic subscribers in the Portsmouth area have already been connected to cable telephone and the first local buisness is expected to be using Nynex later this month. The service is available so far to homes in parts of Waterlooville, Purbrook, and Cowplain. Cable has just been laid in Wymering and Paulsgrove and workmen are currently in Hilsea. Bedhampton, near Havant, is next on the list. South East Hampshire has 7,400 Mercury subscribers, with 7100 in West Sussex. Mercury expects the figure to increase as local cable-laying continues. Under the non-cable Mercury system, users still have a BT line into their homes or offices and pay line rental. Subscriptions to Mercury costs 8.81 pounds a year and a PIN number is programmed into the telephone to access the Mercury network for long-distance calls. With cable, dialling does not change and there's only one bill. The company claimed calls could be as much as 35 per cent cheaper than BT, which charges by whole units even if they are not all used. Mercury charges by 100ths of a second. Interesting or what?

I thought readers may be interested in a story that appeared in the {Portsmouth Evening News} on Tuesday 14 April entitled "Natural Monoplies? A force to be reckoned with in the near future?" Read on ... Two teenage whizz-kids are laying plans to dig up roads near their Locks Heath homes so they can link their friends to a private telephone network. And Fareham council says it cannot see a reason why the proposal should be turned down. Riza Sobrany, aged 14, and Matthew Furber (13) have spent three years building a telephone exchange in a garden shed at the bottom of a Locks Heath garden. The two schoolboy telecommunications boffins have got the exchange working and a waiting list of customers for their brainchild named `Retsu Communications Empire.' But before they can take their first calls through the exchange they need permission to lay cables to the homes of a dozen friends waiting to join the network. A spokesman for Fareham council said the authority would be prepared to grant a road opening agreement to the two schoolboys if they fullfilled the same requirements as any other private company wishing to carry out works on a public highway. The spokesman said "When I first heard about it I was a little bit puzzled. But having looked into it I can see no reason why we should say no." Matthew of Park Glen, Park Gate, said: "We've applied for a road opening agreement and we have a contractor who will do the work for free." The exchange was built using dismantled equipment from the former British Telecom exchange in Locks Heath, which was modernised in 1989. It has cost the two boys just ten pounds in spare parts. The very first customers on the exchange were Riaz's parents, whose house at the top of their garden is connected to the shed where Riaz and Matthew spend many hours. The entrepreneurial duo plan to charge their customers just five pounds per year subscription and 3p per minute for standard rate calls between *am & 10pm. Cheap rate calls at night would be free. Construction giants Pirelli said it could carry out the work for free pending a survey. Spokesman Nic Hart said the company commended the duo's enterprise and already had the two million pounds blanket insurance cover required to carry out the works. And he said Pirelli would provide the cable for the job.

Organization: Motorola Codex, Canton, Massachusetts Date: Fri, 8 May 1992 15:26:27 GMT A friend of mine is looking for equipment to run an FM radio remote broadcast from a distant (1K miles?) location. The signal to be transmitted is stereo (maybe mono if necessary) with 50Hz-15KHz bandwidth -- I don't know the SNR requirements, but I would guess 50dB or so. Obviously the solution used for local remotes (an equalized copper pair) won't work. Is there any solution out there that works over fractional T1 or similar digital services?

I have been having a problem lately where another person can pick up his phone and have it interfere with my data phone line. I don't think he is aware of any disturbance because he does not respond to me asking him questions across the phone line when I encounter him ("What is your name? What is your phone number?") but there is nothing like some touch-tones to terminate an error- correcting modem's connection. I have checked my outside hookup for signs of "beige boxing" while this was happening. Nothing. Neither have I noticed any long distance calls not made by myself or my roommate (we keep logs). I have not spoken to the local telco about this because the line is being used to run a BBS. While I am almost sure that I am running a BBS that would be considered a hobby under Idaho PUC, I don't want to take any chances. Can somebody offer a probable diagnosis? I will eventually have to go to the phone company about this sometime, but I'd like to face them more prepared than I am right now, about the "mystery guest" and the PUC.

Last year New England Telephone entered the 20th Century and we got this great new feature -- touch-tone dialing! In a fit of euphoria I went out and bought a few programmable phones. I quickly realized what a pain it is to program each phone. This is complicated by the fact that I am cheap and bought three different brands at various clearance and going-out-of-business sales. (GE is the best program feature wise.) Then I realized that business systems are centrally programmed; and I ask why not a home system? I checked around and two-line business systems would start at around $700! Plus, they may not have the features I need. So, I'm asking does anyone make a centrally programmed system that is useful for a two-line home? Here's my situation: 1) We have two lines - one is our primary private line and the other is used for work (modem). We pay for the private line and use this line for all our family business. My wife's employer reimburses us for the second line -- so we don't want to put personal toll calls on that line. Although we may use it for toll-free calls if our primary line is in use. The two lines are daisied-chained throughout the house. 2) I would like a centrally programmable system that allows us to use standard phones, i.e. supports some sort of "speed-dialing", supports two lines, a reasonable price! ($150 for the programmable unit?) Does such a beast exists?

(Update on "Modem Tax") (forwading headers removed) URGENT! I GOT THIS FROM THE SHIRLEY HUGEST BULLETIN BOARD SYSTEM (617 937 1234) AND YOU GOTTA PASS IT ON: Four years ago, the FCC tried to change the way it classified telephone access to Information Service Providers such as Comp-U-Serve and Dial-a-Porn. While this idea, erroneously called a "modem tax", was dropped and has never been revived, a far more insidious threat to the way we use our networks has been proposed instead. The FCC now proposes to tax network chain letters. All network connect time spent sending, forwarding, distributing, or editing network rumors and chain letters such as the "modem tax" and "Craig Shergold is dying" will be subject to a tax of up to $5/hour. All networks which propagate these messages across public, leased-line or microwave radio facilities will be required to analyze their network utilization and determine how much time and bandwidth was spent on these chain letters. A semi-annual payment must then be sent to the FCC's Bureau of Redundancy Bureau. I know this is true because I heard it on the Harry Lipschitz show on WLFD radio in Passaic, NJ, where a caller heard about it in an article written in the Globe. They even read some of the details of what the tax will cover and it's huge! A message will be counted as a network chain letter if it meets such broad criteria as: a) uses the phrase, "Modem tax", without explaining that it's a hoax; b) does not contain a date, so that it cannot be shown to be old; c) cites as authoritative hearsay like, "I heard from somebody who heard on KGO Radio that the New York times said that..."; d) cites as a source a Bulletin Board System and gives a phone number that has long since been disconnected or changed; e) includes addresses of present or former members of Congress ca. 1989, with a suggested text of a letter to send them, citing an aforementioned or similar chain lettter topic; f) requests people to "pass this along urgently" or similar language designed to encourage the spread of disinformation at the speed of light; g) has had its original headers removed, making it impossible to trace to the original source. This tax would obviously cost us very much money, and could conceivably lead to the end of computer networking as we know it! Please pass this along urgently to everyone you know. And also send protest letters to: Congressman Wilbur Mils Tidal Basin Washington, DC 20000 and Commissioner U. Ben Hadd FCC 1919 M St. NW Washington DC 20554 letting them know your feelings on this subject. [Moderator's Note: Fred, I love it! That nasty rumor keeps going around.

I found it rather interesting, and all too typical of telco behavior: * From : Paul Robinson (04 May 92 07:09) * To : All * Subj : AN INCIDENT IN DC I live in the Washington, DC area. At our address in DC, we had installed two telephone lines, one for me and one for a relative. The phone lines are billed separately. On one of the lines the person there ran up a large long distance bill, about $4,000. What I gather about it is that they figured the phone company would disconnect them in a month. For some reason the phone company kept sending threats of disconnection and kept advancing the dates they would disconnect. I have discovered the person never asked the phone company for an extension, the phone company just kept putting off the disconnection date after sending serveral notices -- each with a specific date that they would -- which I have not figured out why. Eventually C&P Telephone company disconnected the service. It was made clear to this person that they were not to make long distance calls on the other phone; and they did not. The other bill was normal and there were no unusual charges. Then one day the phone did not return dial tone even though it did earlier that day. I went to a pay phone to discover why the phone wasn't working. This other line is billed to someone other than that relative. The phone company representative at repair service said that the service had been disconnected for nonpayment. I called the business office. I got this woman who told me because the person who ran up the large phone bill was still living in that house, they had the right under tariff schedules to discontinue all phone service -- even that issued under another name -- when someone else there has been disconnected for nonpayment, because they had so many people who had not paid their bills then had someone else there get the service turned on. I told the woman we are living over a dentist's office that shares the same address as us. Does that mean that they can cut off HIS service too? Does that mean if an employee at the Pentagon doesn't pay his home phone bill they can cut off the Pentagon's phone service!? She tells me the only way I can get service restored is to send them a notarized afidavit that the person had left. Since they are paying part of the rent there, evading phone service payments or not that would require a formal eviction -- this person used to work for a real estate office and knows every trick to prevent eviction, and could easily stall one for six or eight months -- and I've had no problems with them paying me so I didn't see throwing them out on the street was an answer. Actually, as I understand it, they just stopped paying their bill on the assumption the phone company would disconnect it in a month. The phone company took four months before they disconnected the service. I found this was hard to believe that the phone company could cut off one person's service due to nonpayment by another. Further, I considered that the person who didn't pay the phone bill could sue the telephone company on the grounds that their action against a third party jeopardized their life -- by throwing them out on the street -- and that the tariff might not be constitutionally valid, since it holds one person responsible for the debts of another which they have no control over, and thus get a court order to restore service which the bill has been paid on. Or they might sue me, then I could issue a third-party suit against the phone company in the interim. But I said, before we take a drastic route, let me see exactly what the tariff says. I had asked the clerk the number of the tariff but her claim was she didn't know which one it was. I went down to the telephone company office and asked to see the local tariff schedules. After the usual bureaucratic runaround -- anyplace I've gone they don't want to show you the schedules or can't find them. (In California I once had to call the business office and threaten to pay my bill through the PUC claiming inability to discover tariffs, to get them to show them to me) -- I got to see the tariff schedule. I went through all of it. The phone company can disconnect for nonpayment of the particular account. It can disconnect for nonpayment of long distance carrier charges. It cannot disconnect for nonpayment of directory advertising. There was no tariff indicating that service may be disconnected for failure of a third party to pay a bill issued to the third party, nor anything of any nature permitting service issued to one to be disconnected for the actions of someone else on a different line. So, at the business office, with tariff schedule in my lap, I called up the billing office to ask about this. They informed me that my service would be turned back on in two hours. I never had to even ask which so-called tariff it was. The service was restored in about an hour and a half.

If the crisis is not nationwide, you can frequently make long distance calls when local calls are blocked. These calls often use different facilties than the local calls. Most calls in these kinds of crises tend to local -- calls to families, calls for help, calls to tell people not to come to work, calls to tell your buddy the cool thing you just saw, etc. As a result, if your city has a disaster, and you need to contact your family, call a long distance friend or relative, tell them that you are OK, and leave a message for your family. Have them call the same place to send and receive messages to and from you. On a smaller scale, voice mail seemed to help alot as well. With people moving around so much, and lines being so busy, if you were patient you could eventually get to your company's voice mail, leave messages for others, and collect yours. This again emphasizes the value of leaving detailed messages on voice mail, not just call back numbers. Just some food for thought. Dave davep@u.washington.edu ------------------------------ From: polk@girtab.usc.edu (Corinna Polk) Subject: Calling Card Fraud on "48 Hours" Date: 8 May 1992 12:11:04 -0700 Organization: University of Southern California, Los Angeles, CA The CBS show "48 Hours" ran a show last week on scams and their lead story was on calling card fraud and how prevalent it was in bus and train stations, and in airports. They had a camera hidden on a bank of phones and had a reporter go in to use a phone and gave the operator her calling card number vocally. It was unreal to see all the people who leaned in towards her as she began to recite the digits. There were at least half a dozen people who moved in. After she completed the process, the police moved in and grabbed a couple of the people there. The guy at the phone next to her already had it written down (this was a number that MCI had given "48 Hours" to use and abuse in their report). They had plenty of tapes of people leaning to see digits being pressed on the phones, and had a printout of calls that had been made using the reporter's number within minutes of her "giving it away". People had called half a dozen different countries! This raised two questions: 1. Why do operators still ask you for your card number? I assume that if they complete the call in that manner they can bill for an operator assisted call and thus charge more. But wouldn't it make more sense to either flag certain numbers (pay phones in busy locales) for non-verbal calling card ID unless the customer has no other way to complete the call (slimy COCOTs) or to instruct operators to not ask for the calling card number first thing? 2. When the police did pick up people at the pay phones for selling the numbers, apparently there was little they could do with the offenders. According to what I heard (and we all trust TV journalism) it is only illegal to steal someone's calling CARD, and not the number. The only way to charge someone is to prove that they used the number to make unauthorized calls. It was a great scene though: a camera watching the phones, a guy in the ceiling watching what was going on, half a dozen people watching an analyzer spitting out numbers called with phone numbers, a woman calling owners of the phone codes to see if they had possibly just authorized a call to Bulgaria to be made from the bus station, and a bunch of transit police waiting for their chance to arrest someone. But even the guy they showed who had written the reporter's number down wasn't really charged with anything. They just held them in jail as long as they could without charging them and then released them. Doesn't it seem like there should be something else in place if LD companies really want to fight fraud? ------------------------------ From: dougb@novell.com (Doug Barlow) Subject: Digital Cordless Phones: Do They Exist?

The company I work for is a memnber of the "Bay Area Gigabit Testbed", so I've been following the planned broadband ISDN offerings pretty closely. What is currently scheduled for availability to subscribers sometime in 1995 is 155 Mb/s ATM service over SONET OC-3c fiber-optic links. While 155 Mb/s is a lot, it's not nearly enough to send a two-hour movie in three minutes. Raw NTSC video ("network television") is roughly 60-80 Mb/s (depending on coding). Compressed with lossy JPEG but still with "good quality" it's between 10-20 Mb/s, depending on motion. On the other hand, a first-run movie is more on the order of 10 Gb/s raw data rate (4000x3000x36 x 24 frames/sec) as it comes out of the movie magicians' morphing engines. Highly compressed, however, it could just about fit within a single OC-3 channel. So the transmission of a movie-theatre quality image could occur in one-to-one realtime. Maybe the reporter got it wrong? Perhaps they meant it would take three minutes from "dialtone" until the videotape/videodisk had been fetched from the library and was mounted on the player? > Pac*Bell has not the slightest interest in offering ISDN to the masses ... > So what is Pac*Bell doing to move ISDN along? Probably nothing. > Pac*Bell has ABSOLUTELY NO PLANS at this time to offer basic rate ISDN > to ANYONE, business or residence ... John, this is simply not true. I can get PacBell ISDN service at home *today*, for $45.15/month for two lines -- one analog, one digital 2B+D, or "three dialtones for $15/mo/dialtone" -- or $58.97/month for two ISDN lines (four dialtones for $15/mo/dialtone). True, the tarriffs are a bit weird, requiring you to have Centrex service, with a whopping $585 installation charge -- of which $300 is "establishment of Centrex service". But the intra-LATA call rates are exactly the same as voice call rates. [Inter-LATA depends on one's ISDN IEC carrier. Some are the same as voice; some are a *lot* higher.] And ISDN Basic Rate service is only available within 18,000 wire-feet of an ISDN-provisioned CO, which at the rate they're going I will absolutely agree with you is nowhere near universal access ... yet. But PacBell *is* selling and installing ISDN today, in some non-trivial quantity. By the way, they've just about given up trying to push it based on the data transmission capabilities -- not enough of their anticipated audience seems to care (so says an ISDN Makreting Manager). What they're doing now is going after the high-volume business users, promoting the fact that a single ISDN line gives you *two* dialtones at a monthly cost *less* than two standard business lines. This marketing strategy seems to be working better for them than pushing the data capabilities. If you absolutely *must* have ISDN today and are outside the 18kft limit, there's a way to get ISDN in groups of eight lines ABSOLUTELY ANYWHERE AT ALL for about the same price as a T-1 line. In fact, that how they do it: They run a T-1 line [with the usual repeaters every 6000(?) feet] and stick a D4 channel bank on the end of it and a thing called a "Bright Card"(?) on that, giving eight ISDN "U" interfaces. [Note that this is *not* ISDN PRI (23B+D), but merely eight BRI lines (each 2B+D).] Each of those can then be run in any direction up to 18kft from the termination. But it's not cheap. A typical "medium-short" run for "ISDN Extended" is over $7000 to install and $1200/mo (or ~$75/mo/"dialtone"). Rob Warnock, MS-9U/510 rpw3@sgi.com Silicon Graphics, Inc.

My system is a 486/33 with a Telebit TB+ on a specialIX port running SCO Xenix 386. Its a dog with an average of 32 Users, the response time is bad. I am not sure how this would affect the modem, the SI board is an intelligent board with RTS/CTS flow control. System A is a 386 with a T1000 on COM1: with the interface locked at xxxx baud. System B is a 286/12 with a T1000 on COM1:, the interface is locked at xxxx baud. When system A tries to send a 20K file to system B using UUCP, the line is lost. When system A tries to get the file from system B using UUCP, the line is lost. All systems are set with m2s61=255, micro-packets disabled and tone before packets, the modems are not retraining at the point where the error occurs. On my system I have s58=2s68=2, on system B, s58=3s68=255, on system A, s58=3s68=3. When I send a 1.2MB file to system A, the file transfers fine, when uucp changes to to slave mode and tries to retrieve a 170K file, the line is lost. When System A calls me and attempts to send the file, the line is lost. When I try to download using Zmodem from A to me with Xmodem spoofing on (because I was going to try Xmodem if Zmodem failed), there were errors but the file made it. When I uploaded the same file to system B using Xmodem with Xmodem spoofing, the transfer took a long time, had a large number of errors but it finally made it. With Xmodem, there were a lot of pauses when nothing was being sent. With UUCP, the transfer procedes for a while and all of a sudden I start receiving alarms, eventually it will abort with line lost. I had thought that 'spoofing' meant that the modems would take care of error correction between themselves and return the user an error free data transmission. Why am I seeing errors with Xmodem? What is going on here? Can you help me? Does anyone have list of the undocumented features in the Telebit modems? I know of some of the information for disabling micro-packets and adding tone before packets, and I remember some S registers have undocumented 254 and 255 values.

Richard McCormick, chairman and chief executive officer of US West, said Fax Mail is the first of many such enhanced information services the company plans to offer. He said future services will be based on innovations in voice, fax, and data communications. "The desire for these services is exploding," McCormick said. "We see a total market opportunity within our 14-state territory of more than $1 billion by 1995, and we expect to capture a significant portion of that market. In just the fax market, we see the number of machines doubling and moving from central locations to desktops, automobiles and homes," he said. McCormick announced Fax Mail at US West's eighth annual shareholders meeting, being conducted for the first time outside Denver, the company's headquarters. "It's especially gratifying to be able to tell our shareholders about the introduction of Fax Mail here in Seattle," he said. "We've been talking about new information services -- and here they are." Bill Gillis, president of US West Enhanced Services, the recently formed unit that will market Fax Mail and other new services, said Fax Mail electronically stores incoming faxes until a subscriber chooses to print them. Fax mail subscribers can then print fax messages on any available fax machine, anywhere, in complete confidentiality. The service also works with personal computers equipped with fax modems or fax cards. All Seattle area telephone subscribers will have access to Fax Mail, regardless of the company that provides their local service. Each fax mail user is provided a personal fax telephone number to which faxes are sent and stored electronically. When a fax is received, Fax Mail can automatically notify the customer by depositing a message in voice mail or beeping a pager. The user then calls Fax Mail from any Touch-Tone phone, enters a personally selected security code, and enters the number of the fax machine where the subscriber wants the faxes printed. "Fax mail allows you to retrieve all of your personal faxes with a single telephone call and eliminates the inconvenience of trying to track down faxes and messages," Gillis said. "For frequent business travelers, that represents a significant cost savings." Customers wanting more information may call 1-800-945-9494. 1 May 1992 US West Contacts: Lisa Bowersock (206) 345-6885 Mike Szumilas (303) 294-1627 ------------------------------ From: karn@chicago.qualcomm.com (Phil Karn) Subject: Qualcomm CDMA Specs Available for FTP Organization: Qualcomm, Inc Date: Sat, 9 May 1992 19:23:50 GMT I am happy to announce that Qualcomm has released the entire text of the CAI (Common Air Interface) for its CDMA (Code Division Multiple Access) digital cellular technology.

Although we have most of the hard spots figured out, I have a couple of questions, as well as a request for general comments from anyone who has been involved with this sort of conversion. 1) The telephone service group has pretty much determined that the use of TAU units and a modem pool will take care of dial-out needs. Are there any particular circumstances in which this is not a good solution? I suggested that services requiring special front-end programs (AppleLink, CompuServe Navigator or Information Manager, America OnLine) might be problematical, but the Ericsson people say that the TAUs respond to Hayes type AT commands so it should be no problem. 2) Can anything be done with Shiva NetModems? These are shared devices on an AppleTalk network that allow modem dial-in and dial-out services (when you dial-in you appear as a node on the zone of the network where the NetModem is located). The current suggestion is that we'll have to get a separate analog line. 3) A UNIX based "gateway" system is being hooked into the switch to control dial-in access to the campus fiber-optic network. Any particular words of wisdom here? 4) One of the groups here has an audio teleconference bridge that appears to require analog lines. Are there similar systems for digital setups? 5) We have a system that forwards calls into a PA system in a television studio that the vendor has told us is not compatible with a digital system. Run analog lines to it too? I am not on the implementation team for this changeover. My concern is that none of our ongoing project work gets disrupted by this. We have a lot of strange setups in this building. Thanks for your thoughts.

Just a note on the state of ISDN here in the People's Republic of Massachusetts, in case others are interested and/or need some amusement today. While it is getting better as Morris states, the improvement is happening at a ponderous pace, as befits the phone company and other dinosaurs. I suspect that my problems may be symptomatic of the nation at large, so I figure I'll post this little story and see what, if any, comments come back. A little background: I've been looking to upgrade the current SLIP connection between my partner's home and the office, which is currently running over normal residential lines and a pair of v.32bis/v.42bis modem. I was hoping that basic rate ISDN would enable me, by bridging the B channels (thanks Morris and Richard), to step up to a 128K connection. I hoped that at that speed, NFS mounts and NXHost'ing of apps would become feasible (they aren't now). Both locations are served out of the same Central Office (CO) which is a 5ESS and is ISDN capable. At the moment we pay about $14/month on each end for our connection and we keep it up 24-hours a day or as needed for various other purposes. Quick disclaimer: after literally one year of calling the phone company and the Mass Dept of Public Utilities with inquiries about ISDN, I have developed a visceral aversion to regulated utilities and the technology-challenged liberal arts/law school graduates who regulate them. When I have a really bad day, I call these guys up, (especially the DPU) because they give me the perfect means of venting a lot of spleen without the guilt of doing so on someone who doesn't deserve it. :^) The point is: salt the little parable below to taste. Anyway, this past week, I finally got someone on the phone at New England Telephone who could actually tell me what services the State of Massachusetts was now allowing me to buy. I WAS APPALLED (but not surprised :^) ) The conversation with NE Tel started out just rosy. The sales guy informed me that ISDN was available out of my CO (a fact that I knew a year ago and which influence a relocation decision) and that it could be had by subscribing to their Centrex service with quantity one line. Now, I knew that Centrex is essentially renting part of a switch and is typically sold to signicantly larger customers as a way of enticing them not to buy a PBX, thereby cheating the phone company out of its hard-earned return on assets. I was a bit hazy on exactly what Centrex features one can use on a single line, but I let it ride. Since this was a business line (residential customers don't do digital), I would of course have to pay the tariffed business line rate of $30/month. That's fair, gotta subsidize my personal line somehow, and it sort of fits with making me buy commercial plates for my pickup truck (only businesses in MA drive trucks). Anyway, I let this ride, too. Now we add $23/month because this is a DIGITAL line. I asked him if he knew the function of the A/D chips and codecs that are on the line card in the switch that my analog line attaches to. He allowed that that was not really his area. I bit my lip and reluctantly let it ride. Then I enquired as to any usage fees. He said yes, all of this can be had for the low-low price of 9.6 cents/call plus 1.6 cents/minute. I did a quick back of the envelope calculation: $.016/minute * 60 min/hr * 24 hr/day * 30 days/month and came up with a usage fee of about $691/month. I could not let this one ride. I felt a bad day coming on :^) ... I asked exactly why NE Tel felt that I ought to be paying a per minute usage fee when placing an intra-CO call on a non-blocking switch. He assured me that even though this was not his area, those switch services cost real money. I said that I used to program state code in line cards on phone switches for a living and that yes, I understood that I used switch services during call set-up or if I went outside my CO and tied up trunk capacity, but that I knew damn'd well that I did no such thing once the call was established to another line in the same switch. He replied that this really wasn't his area, but he assumed that since it was in the tariff, I must be wrong. I decided to try another tack. I asked him why anyone would possibly be interested in paying $1,488/month ($691+53 on two lines) to get ISDN for circuit switched data calls when one could pay $28/month for a private connection. (Admittedly the $28/month solution is "only" 14.4 up to 56KB, but it ain't 1/50th the speed). At the mention of the words "private line", I could hear a giant switch being thrown. Why hadn't I mentioned that I wanted a private line. Why for "only" $80/month on each end he could provide me with 56KB DDS and they could sell me a DSU/CSU for about $1000/bucks on each end and everything would be just peachy. This was when I said sorry to have troubled him, I'd call back when the DPU actually let someone compete with New England Tel for the local subscriber loop. I've said all of the above to say this: if you're counting on ISDN to provide flexible data connections, you need to be fairly wealthy, given the current regulatory environment. Small businesses need not apply. This is changing in places like NYC and Chicago, but in other places the free market is still seen as a dangerous innovation that has not been proven to work. At this point, I'm interested in hearing from other parts of the country what sort of use people expect to get out of an ISDN connection over the public switched network and how much they anticipate that it will cost. If anyone's interested, over the course of the next month or so, I'm going to give Metropolitan Fiber and Teleport a call and start trying to find out what services they offer. You never know, might not be more that about five years before they're local loop providers and it would be great to get in on the ground floor. I'll post if I find anything vastly amusing or useful. PS: Sprinkle all of the above liberally with smileys. It's all true but its also all funny in an ironic sort of way. Cheers, Ronald V.

Levine) Tuesday's {Microbytes} reports on a new generation of airplane phones under development by In-Flight Phone of Oak Brook, IL. It is headed by John Goeken who was the founder of Airfone and, as I recall, was also the founder of MCI. The new phones are all-digital, and use 12 kilobit channels. The ground stations are controlled by 386 DOS PC clones. On the plane, each phone (one per seat or perhaps group of seats) has a small CPU with a codec that turns the voice into a 64Kb bit stream, and an in-plan LAN passes that to a server that uses a DSP to squash it down to 11.2kbps. There is provision planned for handling faxes, though at the moment all they seem to have is something that passes ASCII to the ground station which then turns it into a fax. It implies that there is also provision for modem traffic, as one of the major complaints about the current scheme is that the fidelity is so lousy that it can't even do 300 baud. US Air is starting trials this month, with American and Northwest expected to follow. The rate is $2/minute, same as Airfone, but without the $2 setup charge that Airfone has. The computer stuff is from Desktalk Systems of Torrance CA, and the radio part from Digital Microwave of San Jose CA.

Date: Sat, 09 May 92 22:59:11 GMT I recently received a new catalog at work which had quite a few interesting goodies in it. The company is Home Automation Laboratories (HAL) and can be reached at 800 HOME-LAB (800 466-3522) or 404 319-6000. It includes: - Several phone and intercom systems, including the much-raved-about Panasonic small PBX/Key phone systems - which I've never seen for sale retail and have failed to purchase in the past. - Many phone accessories, including: A box that answers the phone and demands a password be punched in by the caller before ringing. Apparently this is a replacement "bell" and doesn't ring the callee's phones, so I doubt it works with modems or answering machines and additional ringers would have to be kludged in. Several interesting voice/Fax phone line sharing devices with a new twist: They let YOU or your answering machine answer the phone and it eavesdrops listing for a fax tone. If it hears the tone, it disconnects your phone or answering machine and connects the Fax to the line. They say this is guaranteed to work 100% of the time with any fax or answering machine, including behind a PBX. Another box is similar but listens for an originating modem's tone and assumes it's a Fax call if there's no tone within eight seconds. It says no modem programming is required since it listens for the origination tone, and apparently ignores the answering modem's tone, which must normally occur first. The usual distinctive-ringing detector which routes the ringing line to different devices depending on the ring cadence. Music-on-hold boxes, which can synthesize Bethoven or use an external music source. Dial-uppable devices to eavesdrop on sound, temperature, and external detectors, commonly used to monitor computer rooms from off-site. - Many, many X10 (wireless AC switch/dimmer module/controller) accessories, including PC interfaces, and remote controls which do X10 and infra-red. - Many, many infra-red (standard audio/video remote control) replacement remotes, PC-interface remotes, "wired" remote extenders including several to use existing TV coax for both CATV and run the wired remote detector. - Surge suppressors for everything, including a "whole house" one that connected directly to your breaker/fuse panel!! - Alarms, motion detectors, and closed-circuit TV systems. - Multi-room speaker systems, including interesting impedance-matching devices. - Systems/devices/solutions which combine all of the above into your worst nightmare! :-) The catalog is not terribly well organized and doesn't do a wonderful job of explaining some things, but there are definitely some hard-to-find and interesting items in it. I have no idea what their quality or service is like. Maybe their tech support is all-knowing, helpful, and just waiting for the phone to ring?? (Well, Dorothy and the gang ARE on a yellow brick road on the cover of the catalog, so who knows?) ------------------------------ From: guy@library.calpoly.edu (Guy Martin) Subject: Strange Phone Behaviour Organization: Polycat/Systems Support - Kennedy Library, Cal Poly SLO Date: Sun, 10 May 1992 06:15:32 GMT I was wondering if anyone has experienced the following strange behaviour from their phone ... I try to call my sister in the East Bay (510) from San Luis Obispo (805) several times. I got a busy signal the first few times, which I didn't think was abnormal (she talks on the phone a LOT #:-)), but then when I did get a ring, it was one ring, followed immediately by a "static"y sound with no more ring tone ... I sat on the line, and after about two minutes of the static, I got ring tone again, but it just kept ringing out, until Boom!, I got fast busy (VERY LOUD I might add) ... What is strange about this is that there should have been an intercept recording if there was a network problem, right? Anyone ever experienced this before? Guy Martin -- Polycat/Systems Support | Internet: guy@library.calpoly.edu Robert E. Kennedy Library, Cal Poly SLO | UUCP: voder!polyslo!library!guy ----------------------------- Standard Disclaimer ----------------------------- My opinions are my own! They do not reflect those of the Kennedy Library. [Moderator's Note: The problem might have been very local, within her wires or instrument. If between the CO and the 'network' no problem was seen, the call would have been passed along to your sister, but if the wires somewhere around her were wet or poorly connected, the busy signals you got earlier and the static could be accounted for. The intermittent connection to her phone (due to wet or improperly connected wires) then might have caused the CO switch to do something strange, all the while the CO or network itself saw no problem. Have you since asked your sister if she experienced any problems that day in answering the phone when it rang, or in placing outgoing calls? I've had cases of one ring then silence with no answer, and it turned out to be someone (won't say who!) had accidentally connected the ring of one line to the tip of another, or etc. Once or twice of these calls, then the CO started returning fast busy.

We went to Austin about three weeks ago so Peter could attend a meeting of a committee that he was asked to participate in. We stayed at the Hawthorne Suites Hotel. The rooms were very nice -- like little apartments with a kitchen and a living room. We were pleased to see that the long distance carrier was AT&T. Local calls were fifty cents apiece, and there was no charge for 800 numbers. You could also make direct dial long distance calls for a horrendous surcharge which I did one time when I got frustrated trying to use the Sprint card because the buffer on the modem was too small to hold the incredibly huge string of numbers one has to dial. I wish I had timed the call, but it couldn't have been longer than ten minutes (just long enough to check my mail) and the charge was over five dollars. This for a call placed at three in the morning! When we checked out, we scrutinized the bill and found we had not been charged for any calls we didn't make. The hotel clerk explained that they didn't even do the billing for the phone calls. In fact, we weren't charged for a call we did make, but it was one where I had timed out on the system for taking to long to log in and I guess it was too short of a duration to register for a call (I guess they had a minimum call length before they started charging). Not a perfect experience, but not too bad, either. As a footnote, we went and visited with Peter's parents right before we left for Austin. They were staying at a hotel near the airport here as they had arranged a short layover in Houston so we could visit with them as we don't see them very often. We looked at the card that explained the telephone service, and it said the long distance carried was Allied TeleScam or something like that, based out of Dallas. On the back of the card was a disclaimer saying the hotel wasn't accountable for the service and it gave the name and number of some Consumer Advocacy service to direct complaints to. Kind of tells you something about the quality of the service, doesn't it?

One of them was on the theft of calling card numbers in airports and train stations, and the resale of these numbers to make international calls. Apparently the "going rate" is $10 for an unlimited-duration international call. A reporter made a phone call using her MCI calling card in Penn Station in Newark, without being careful to protect it, and there were apparently at least five people around her trying to get the number. One of them asked the camaraman if he got the number. One guy was pretending to use a phone while actually trying to get calling card numbers of the people next to him. In a later interview with MCI's fraud control people, it turns out that the stolen number was used two minutes later. In the process they gave viewers a nice shot of the MCI calling card number. Presumably this card has been cancelled already. There were also some nice shots of call logs, identifying calls to Algeria, Egypt, and Switzerland, complete with apparently real numbers, and computer screens of AT&T Security with what looks like login passwords on them. The police had cameras monitoring the phones and were logging all the numbers. Several arrests were made. One of the number resellers didn't think he was doing anything wrong. It is apparently New York law that you have to be caught with a stolen calling card, not a calling card number, in order to be prosecuted, unless you actually make a phone call, which the resellers don't. Also covered were the pigeon-drop scam, loan scams, fake lottery ticket scams, stolen cars/fake auto accidents/insurance fraud taken to the point of being an industry, and home-repair scams. Parts of the program were sponsored by MCI, with a pitch for their "Friends of the Firm" program, the business equivalent of "Friends & Family". Gordon L.

Official spokesmen and the truth are not always positively correlated. Two months ago, when that fortune-telling company was charging people for 800 calls, I called first local NyTel and then AT&T about this practice. NyTel punted to AT&T. AT&T adamantly denied that any such thing could possibly occur, and also denied that such a thing as the {USA Today} billing for an 800 call could occur either. Twice the person I talked to put me on hold for several minutes while she checked her info. When she came back she continued to deny this. Whether she was playing a semantic logic-chopping game with me, in that she considered such charges to be for information provided during the call, and not for the call itself, or whether she, and her supervisors, had really never heard of such things, I don't know. (Other organizations also do this. Last year, after a power blackout, the official NiMo power company spokesman told the newspaper that all service had been restored by such-and-such a time. I wrote a letter to the newspaper saying that I knew from personal experience that this was false. The paper published my letter. The day it appeared, the spokesman wrote me a full-page letter of explanation.

Date: Fri, 8 May 1992 09:16:08 -0500 For those who missed this article in {Information Week}, it shows how businesses are dependent on robust software and hardware (and disaster recovery plans): "Phone companies may have to start paying for service outages with more than their public image. Under a bill proposed by Rep. Edward Markey (D-Mass.), carriers would pay fines to regulators and refunds to customers scaled to the severity of a network outage. When 25,000 lines or more go down for one to six hours, carriers would have to refund 1/4 of the previous month's phone bill to their customers. When the outage lasts 6 to 12 hours, customers would get back 1/2 their bill; outages over 12 hours would require carriers to refund the entire bill. Moreover, carriers found to be 'negligent' could also face penalties of $10,000 to $20,000 PER MINUTE (!) for disrupted service." OUCH! [Moderator's Note: It will never become law. Telephone service is governed by tariffs, one of which clearly specifies that the most a customer can expect in the way of compensation is a pro-ration of the month's bill based on the length of time the service was out.

The 900DX is one of the first of the new breed of 900 Mhz cordless telephones. It uses 20 channels from 925.5 to 927.4 Mhz (handset to base), and 20 channels from 905.6 to 907.5 Mhz (base to handset). They do not list a power level, but simply state that it uses the "maximum power allowed by FCC". The signal path is fully digital from base to handset, and handset to base. This prevents casual evesdropping from people with scanners, but will not provide high security. The signal, when tuned in on a scanner, sounds like a dead carrier, with the occasional 'pop' or two. Nothing even resembling voice is present. The weight of the handset is 335 grams, and is 19.5 cm x 5.8 cm x 3.5 cm, excluding the short antenna. Range is extrordinary. They claim 2600 feet, on level ground. I was able to use the phone for almost a 1.5 block radius around my house, in a typical suburban environment. Because the signal is digital, there appears to be a go/no go type of response. When you are on the edge of the coverage area, there is a slight 'popping' sound, as the signal comes in and out, but no static at all. When you have moved out of range, the handset is silent, except for a 10-30 second 'beep' tone to let you know that you are out of range. Noise is non-existant, even in the harmonic-rich environment of my computer room, where my 46/49 Mhz Sony unit is almost unusable. The base unit comes with a hands-free option, and a separate keypad so that it may be used even if the handset is not present. An intercom facility is provided, and works well. Now, for the bad news. The audio quality is best described as 'acceptable'. True, there is no additional noise. The level of the received audio is low, even with the four position digital volume control at maximum. The level of the transmitted audio, however, is even worse. On international calls, callers were often unable to hear me, and I was forced to change to either the Sony or a regular wired phone. There are several artifacts audible to the user, and to the called party when using the phone, especially when high audio levels (like ring signals, SIT tones, and touch-tones) are present. I suspect that it is using an 8-bit A/D, D/A convertor, with (perhaps) some form of delta compression. Even on local calls, the most often heard phase when using this phone is "pardon me?". I started to get in the habit of shouting when using the 900DX! So far, I have tried three of the 900DX phones. The first one was significantly worse on the RX audio, but all were not really good enough. Calls to the 800 number for tech support (800-624-5688) yielded a good response, but they are not able to adjust the outbound volume level. Bottom line: The phone is going back to Macy's. I really like the idea of a fully digital phone, but the Tropez unit is just not quite there yet. I'll try the Panasonic unit next -- I've had good luck with their cellular phones, and answering/fax machines.

My understanding was that, in general, a telephone subscriber accepts responsibility for the charges incurred for calls placed through his phone line ... but does this include other goods or service purchased via my telephone? Am I any more responsible for the purchases someone makes using an 800 number (and says to bill it to *my* phone) than Southern Bell is responsible if I go to a Southern Bell pay phone, place an order, and tell them to bill it to *my* credit card. It might be argued that someone billing the charges to my phone is guilty of fraud, just as I would be if I billed something to a someone's credit card without authorization. But that's a vastly different issue. > "We are especially concerned about any charges that appear on > a phone bill," said McEldowney, "because in some states people can > lose phone service if they don't pay such bills." Can someone identify the states or phone companies that are still trying to do this? The local phone companies only have a contract to provide billing services ... I assume that, by tariff, the phone companies must provide service to all comers who are not in arrears *with the local phone company*. If the local phone company STILL doesn't understand this, then the state public service commission needs to get involved. If the state public service commission doesn't understand this, then they need to be booted out.

Besides, you obviously have the same misunderstanding that most people have. I don't work for the "MasterCard billing center", as there is no such entity. MasterCard doesn't bill cardholders; issuing banks bill cardholders. Nobody bothers to hack MasterCard, because there isn't much worth hacking at a not-for-profit corporation with only around 1k employees. Actually, if our phone system supported DISA, I would expect people to try and phreak that. But since neither or telecom manager nor our security manager are morons, we don't have a DISA number. And in my entirely personal opinion, since it is cheap, practical, and much, much more secure to use something like AT&T's VTNS or even hand out calling cards than to use DISA, after all the publicity on the risks of DISA, anybody who installs DISA on a PBX is a moron, and more or less deserves whatever happens to them, to paraphrase "Canada Bill" Jones. (And if it's true that there are PBXs out there that come installed with DISA turned on and standard passwords, anybody who buys one of these should, in my opinion, sue the installer for negligence.) I will not comment on the credit fraud case you mentioned or any other specific case; it's not my department. Contact Richard Woods, MasterCard International, 888 7th Avenue, New York, NY 10106. In general, well, you don't have to work here to know that yes, credit card fraud is up, and MasterCard's security department has been very successful in helping to track down and prosecute credit card fraud rings, world-wide. But given that credit card frauds are stealing real merchandise, the comparison between phreaks and credit card fraud is inappropriate. Steve Forrette wrote to remind me that if a Dutch phreak blue-boxes his way into the international trunk lines and calls elsewhere, the PTTs end up having to fork real money over to each other for trunk time. Look, a mechanism already exists for disputing charges. When no customer can be proved to have made the call and when the originating PTT can't collect, the receiving PTT should waive the charge ... and they should BOTH work on making it harder to phreak. If all the money that went into phreaking investigations and prosecutions went into network security and customer education instead, there wouldn't be phreaking. And finally, to that nameless person in 206: You admit yourself that your own telecom department knew about the dangers of unprotected DISA. And you let uneducated end-users manage their own phone systems, knowing how dangerous it was? No wonder you asked that your name and company be withheld. J.

This was a very interesting message that made me think of a few questions. If someone in the know can spend some time letting us know more details about the techniques used to lay trans-oceanic cables, or point to a good reference source, I'd appreciate it. Some of the things I'd be interesting in hearing about include how the cable is spliced together. I assume that the ship didn't have 3,250 miles of continuous cable on a big spindle. Does another ship provide additional cable every mile or so? How do they lay a cable part way? I assume that if it's half way across the Pacific they don't simply let it drop to the bottom and hope they find it again. Is it anchored to a buoy? Finally, what if the cable develops problems; can they go down and fix it and is the topology of the ocean floor and the depth a serious concern?

I fail to see where, in legitimate deals, you'd give out your checking account number. In the matter of CREDIT CARD numbers, I've previously seen advice that you should not give out such a number in a call you did not originate; however, the checking account numbers, according to what I have read, were given out during calls originated by the VICTIMS. [Moderator's Note: One legitimate 'deal' where you give out your checking account number is when you ask Compuserve to bill via Check-Free each month. Another legitimate 'deal' where you would give out your checking account number is when you apply over the telephone for (such as) the AT&T Credit Card. I consider both Compuserve and AT&T to be reputable organizations. They both do it ... The important point to remember about 312-296-9000 is they don't call anyone and ask for information ... they let their GREEDY victims -- people who expect to get a free vacation, etc -- call them. It seems to work nicely.

I've seen sample pieces of the North Pacifc Fiber. The topology is of considerble importance, and the differences in types of cable are good indicators. Some of the cable is as small as about 1 inch in diameter (most of which is sheathing for protec- tion). It gets larger and larger depending on how much armor is added! There are five or six different sizes in use. At the point where it comes on shore it is about five inches, and the added part is almost all steel armor. That portion is also buried. The North Pacific Fiber is presently being repaired due to problems just off the Oregon coast. I could guess at various ways they might locate the cable, but I really don't know what they do to find it. I do know that it is located and hauled up very quickly. My understanding of the current situation is that it is up on three buoys, they have replaced one repeater and spliced in some new cable ... and it was supposed to go on line Friday night but it did not pass a 24 hour bit error rate test.

I believe that you assume incorrectly. I've seen pictures of a cable vault in the Long Lines and it is truly enormous -- there was a guy supervising as they laid cable into the vault and he looked like a fly, the vault must have been over 50 feet high. They've got to splice the cable into a continuous trans-Atlantic length at some point, and it'd seem to me a heck of a lot easier to do it while the ship's at the dock so they can test it and if need be repair it before they go out into the middle of the ocean. > Finally, what if the cable develops problems; can they go > down and fix it and is the topology of the ocean floor and the depth a > serious concern? Yes to both, there were some notes a few months ago about how a trans-Pacific cable had failed and they went back to inferior satellite conections while a ship steamed out to the middle of the ocean and spent a few weeks fishing around looking for the cable so they could pull it up and fix it. I'd expect that with modern navigation aids they should be able to record within a few feet the route that the ship took as it laid the cable. Close to shore they bury it, but once it gets deep they lay it on the ocean floor so it's just a matter of trawling until they find it.

Cable is carried in big round holds, but they don't rotate; the cable is pulled out layer by layer from the top, having previously been carefully loaded in port. Splices between sections are done on shipboard when necessary. The cable isn't just dropped overboard; the ship tows a heavy plow that makes a furrow and buries the cable, at least in areas where other ships are likely to be dragging anchors.

When I was in the planning stages for a fiber run between my office and my home, NJ Bell suggested that I might want to use the installation services of the local cable company, as they did a bit of fiber work. [This is in Jersey City, and the local cable company is Cable TV of Jersey City]. They ran my fiber for me. While they were doing that, the mentioned that their antenna to studio feeds were on fiber, and that some of the local- origin programming was delivered to them via fiber. They're in the middle of some upgrade work right now - they may be using fiber for their main trunks these days. Perhaps your local cable company is doing something similar?

Should I call > Repair Service? First, why worry about it if it is not causing any problems? Most modern telephone equipment is designed to be polarity insensitive. Old 2500 sets will not work if the polarity is reversed, and many PBXes are sensitive to polarity reversals, mainly because polarity is significant on trunks. However, given that there are so many opportunities for the polarity to get switched (in the CO, in the outside plant's many terminal locations, and even in your home), telco repair would be run ragged if everyone called about such a trivial problem. In essence what I am saying is, if the polarity reversal bothers you, flip it yourself. And if the only reason you know about it is because you happened to measure it with a voltmeter, then find something else to worry about. John Higdon | P. O.

I'm the one who asked why my recently-purchased used touchtone phone wouldn't generate DTMF; the answer was to swap the red and green wires. This worked fine, but I noticed that (1) the phone's original polarity had therefore been wrong for not one but two houses in two different towns that I tested it in, and (2) the internal wiring of the phone had obviously never been disturbed before; wires meeting at terminals in the phone agreed in color, etc. Now, either I found at least two houses 16 miles apart that were both wired backwards by the phone company, or something HAS changed regarding color assignments in the local wiring.

In effect, a call *is* made to a 900 number via call-forwarding from an 800 number. So you protest to telco, but everything they see indicates you called a 900 number and should pay.

Union negotiations said the parties are still far apart on major issues, and charged that the company is demanding 19 separate givebacks from its workers, despite its profitable financial outlook. The results of the strike vote by the 5,670 union-represented workers will be announced on Wednesday, May 13, 1992. "We are fighting for our future with GTE," said Communications Workers of America Vice President T.O. Moses. "GTE's proposals would destroy the good American jobs our communities have come to depend on," Moses charged. "GTE is attacking the existence of a full-time, stable workforce in this company. They want to undermine good, stable jobs, that contribute to a good standard of living in our communities -- in favor of substandard out-of-town contractors, temporary low wage clerical jobs, and part-time jobs with inferior wages and benefits. "GTE's insistence on destroying good jobs with good pay, benefits, and a future with the company has forced CWA to seek authorization from our members for a strike," Moses said. "We must let the company know that we are serious about protecting good jobs for the people of our community, and quality service for the customers." CWA is bargaining with GTE Southwest for a new three year contract covering 5,760 workers in Arkansas, Oklahoma, New Mexico, and Texas, represented by CWA Local 6171, based in San Angelo, Texas. Bargaining began on March 31; the current contract expires on Friday, May 15. The results of the secret ballot strike vote will be announced on Wednesday. One of GTE's principal demands is the right to unlimited subcontracting. CWA contends that this would mean no guarantee that ANY union members would have jobs at GTE. The union also argues that contract labor not only threatens good jobs for the communities served by GTE, it erodes the quality of service to the customer. "CWA has been running ads to reach out to customers and apologize for the inferior service they get from subcontractors," Moses said. "We want them to clearly understand that the veteran, skilled workforce that has provided years of quality telephone service is getting pushed out by GTE. We want to do a good job for the customers, but the company just wants to cut corners." "The community knows us," Moses said. "The wages and benefits we make and the service we provide benefits our communities. But GTE's subcontractors bring in people from all over the country. That means that local telephone rate-payers' money goes to benefit communities all over the country, but not your friends and neighbors right here at home. Our communities are losing money through this practice, and it should stop. "GTE is also degrading good clerical and accounting jobs and giving the work to temporary agencies," Moses stated. "Those jobs are primarily held by women, and GTE is jeopardizing some of the only decent paying jobs that clerical workers have in our communities. We're fighting for good paying, stable jobs with benefits and an opportunity to advance. GTE's clerical workers deserve no less."
