Two noteworthy items from when I tried to call the number on Sunday, Aug. 5: 1) The local Southern Bell operator said she cannot (will not?) dial to 800 numbers. I assume they are just allowed to complete inter- LATA calls. The SoBell operator said that I should dial 10288+00 to get the AT&T operator to assist. 2) Same outcome here as John, AT&T operator tried the number and we got an intercept that said that "Your number cannot be completed as dialed." AT&T operator said that they are unable to complete calls to non-AT&T 800 providers. Seems that ANI-defeat schemes which involve going through either the BOC or AT&T operator won't work in this neck of the woods. Anyone got a POTS number for SoBell operator in Atlanta?

One of the problems with designing a good quality DTMF receiver is insuring talk-off (falsing) immunity. Talk-off is when the receiver falsely detects a digit due to non-DTMF audio ... such as when you are dialing the payphone in the bar next to the jukebox. If music is playing (or you are talking) and it produces a momentary condition where two frequencies exist within the bandpass for the tones, a tone receiver could detect the false digit. One way to make this less likely is the make the tone acceptance bandwidth for each tone tighter. Another way is to make the "twist" acceptance (the difference in level between the high and low tone) more restrictive. If you do this, you can have another problem ... some phones may not be able to signal your receiver. This makes DTMF receiver design tricky. If you are building an answering machine with a really cheap DTMF receiver (maybe just some filters to detect a couple of digits) one way to prevent false digit detection would be to lengthen the time required for detection. Good DTMF receivers detect tones down to 40 ms, with 40 ms interdigit time. If you lengthen this to 500 ms, you will "never" get falsing, as the chances of the two tones being present in speech or on the jukebox for a half second is remote.

Now I think Western Union has all directory for the >USA in 410-555-1212. I don't believe there is a TWX network (Telex II in Western Union parlance) in Mexico. US TWX Directory Assistance, from "four-row" machines, was 910-555-1212 until Western Union replaced it with a computer on 910-221-5151. The US TWX Area Codes (for "four-row" machines) were: 510 (entire US?), 710 (NE US only?), 810 (SE US only?), and 910 (Western US only?). As I recall, "three-row" machines used normal Area Codes such as 312 for Chicago. I think "three-row" machines reached Directory Assistance by dialing simply 555-1212, but my memory of Bell System TWX has become rather rusty. Wasn't an operator reached by dialing 954-1212? I've understood that Canadian TWX remains well integrated into the PSTN. The observations of our Canadian friend, Woody, about TWX warbles on 510-555-1212 might suggest that, for Canadian wire centers, separate routing tables will be needed for TWX class-of-service lines vs. voice lines with regard to calls to 510 numbers.

I have only had occassion to dial 999 once in an emergency, though I have done so accidentally a couple of times. Each time, the phone is always answered promptly. When we really needed assistance, because there was a person trying to break into the house, the police arrived within a few minutes, having driven through the town the wrong way and straight across the front lawn to stop the man escaping. Other people I know who have used the service seem to find that it's generally very quick to respond, though there have been notable problems, such as the Hillborough incident. I think, though, that that was more a failing of the emergency services themselves than the 999 service. As far as I can tell from using the phone system, 999 is answered at the local telephone exchange, or in the city exchange for a rural area. It is not uncommon for a conversation with the operator to be interrupted with "Sorry - 999 call. Goodbye" A couple of asides come to mind here... 1) In a lot of towns, you can actually reach the emergency services by dialling 99. This is because the rural exchanges will dial 9 to access the town, a allowing 99 to trigger the service means that rural subscribers can also dial 99, without having to have an operator at the local exchange. It also means that problems are caused. The village where I was at school had three figure telephone numbers on an exchange called Long Sutton. (Though the call box was known as Long Sutton 250X). To dial home to my mother in Winchester, I had to dial to the nearest town (Basingstoke) and then on to Winchester. The code was 992. In their wisdom and desire to remove quaint telephone exchange names, BT decided to move all the phones in the village to Basingstoke numbers, prefixed with 862. (Why 862 when the old Basingstoke -> Long Sutton code was 81, is anybody's guess!) For a while there were actually Basingstoke and Long Sutton numbers in the same village, and of course dialling from the Basingstoke numbers you had to omit the initial 9. Needless to say, many people didn't, and there were an awful lot of calls to the 999 service. 2) I posted something in another group about the choice of 999 and it was suggested I post that here as well. There may well be other versions of this story, but it seems logical enough, and I think I saw it documented somewhere... It was decided to introduce a special number for emergencies after a fire (at a doctor's surgery, I believe). Obviously, such a number had to be capable of being dialled without money from a public phone. The service was first introduced in London, which used directorised strowger exchanges, and so a three figure code was necessary. At the time, it was possible to call the operator from a callbox by dialling 0, and a simple mechanical modification to the phones allowed the dialling of 9 without insertion of money as well, hence the number 999.

I wish they did a better job, too, but I think I know one reason why they don't provide _both_ the full rate and the rate you pay. Some calls cost more with Reach Out. Calls to places within 100 miles or so (but out of state) are often less expensive during evening hours than at night, since the 25% evening discount is better than the 11.5 cent/min. flat night rate. Call your friends in nearby locations before 10pm or else use 10333+. By the way, I recently heard of a plan being offered in SW Bell territory called "Selective Calling," or some such thing. It is like Reach Out for a single area code. Does anyone have details on availability and prices? Maybe my friends out west could be calling me more cheaply than I call them.

Reply-To: John Higdon Organization: Green Hills and Cows Date: 7 Aug 90 20:50:11 PDT (Tue) From: John Higdon In June of 1988, I put a client on Sprint dedicated ProWATS. These lines double as intraLATA WATS, with Sprint billing for the interLATA and Pac*Bell billing for the near-in stuff. These lines are reliably selected by the PBX which has ARS. I left AT&T as the default on the local trunks, primarily for ease in routing "0+" calls over AT&T. Today, August of 1990, a salesperson from AT&T called the client. This is the first contact from anyone at that carrier since more than two years ago. My client turned the gentleman over to me. His message was that a "Reach Out America" plan on the local trunks had gone for some time without any use. Somehow he had learned that my client had "gone with Sprint" and he used the opportunity to tell me that Sprint had obviously been negligent for not cancelling the ROA plan. I asked him why that was Sprint's responsibility, indicating that it was more of an oversight on the part of myself, or, since I don't review those phone bills, my client. He said, "Your carrier should really sort of take care of you and point those things out." Then I dropped the bomb on him. "Actually, AT&T is our carrier as far as those lines are concerned. I never changed the default for those trunks. Using your logic, AT&T was negligent in not notifying the customer in over TWO YEARS on an apparently abandoned ROA plan." He quickly recovered, and offered me "a helluva deal". If we would "switch" to AT&T, he would pick up all the costs PLUS refund all of the unused ROA monthly charges going back two years. I told him to discontinue ROA starting herewith and then told him to consider taking better care of his customers in the future. Then I told him to put his offer in writing and send it to my attention. John Higdon | P. O.

It could be part of a street address or telephone number. In the P&G case, for the past decade, P&G has received several hundred cards and letters DAILY from people who express concern that (in the words of the rumor) 'the chairman of P&G has a pact with the Devil, and shows his love for Satan by the arrangement of the stars and ram's head in the corporate logo of P&G'. Arranging the stars in the logo in a certain way, you see, forms the evil 666. P&G has squelched the rumor several times, only to have it start up again. They finally had to drop the corporate logo they used for a hundred years, it got so hard to deal with. Where telcos are concerned, subscribers whose phone numbers end in X666 have complained bitterly about receiving huge numbers of obscene and/or hate calls, accusing them of being Satan worshippers, etc. The people spreading the rumor are vicious.

It isn't a matter of your knowing the phone number you called, but of too much data being stored on computer media about your life and activities. The law that prohibits the disclosure of the full numbers is the one known as "informatique et liberte"; it is intended mainly to prevent the kind of thing some people have complained about in this forum, that anyone who looks at your credit record will get a very good idea of your personal tastes and lifestyle. In the case of phone numbers, Mr. X probably wouldn't want anyone to tell his wife that all these calls to 4787-XXXX are not to his old aunt. His privacy should be respected, and the information not be disclosed to anyone. Hence, it should never appear in print anywhere (not even on a phone bill), and in fact should not even be stored on France Telecom's computers (in case one of their employees should try blackmail, for example; or in case someone breaks into those computers). >Seriously, how would anyone contest a wrongly charged call ? >Perhaps a better question would be: Are you even allowed to contest a >charge ? Contesting charges is probably more common in the USA than in France (disclaimer: I don't have any hard statistics -- this is just a guess). However, you should still be able to say "I never called anyone in exchange YYYY on that day", in the same way as you can tell a US telephone company "I never called (XXX)XXX-XXXX". Anyway, any form of detailed billing is an improvement on the previous state of affairs (when you only got a lump charge for the month's calls). And privacy is worth more than a few extra francs on a bill (at least to me).

DataSPAN, which consists of both hardware and software, provides a frame relay interface to Northern Telecom's DMS-100 SuperNode and DMS-250 SuperNode digital switching systems. Frame relay is a new packet switching technology that enables high speed data networking over the public switched telephone network. DataSPAN's wideband connectivity through the public network is one step toward Northern Telecom's FiberWorld vision of the broadband public network of the future. "With DataSPAN, businesses can cost effectively tie together branch offices, regional offices and headquarters facilities under a common wideband service offering," said Gerry Butters, executive vice president, Marketing, Northern Telecom Inc. "The widespread deployment of DMS SuperNode switches in the local and long distance networks and the availability of frame relay capabilities will provide corporate data managers with a powerful nationwide networking option that facilitates the implementation of both metropolitan and wide area networks." DataSPAN allows data users to replace dedicated leased lines with a virtual private data network that is offered through their local or long distance telephone company. A virtual private data network provides bandwidth-on-demand, multiple data sessions on a single line, and simplified network management over the public switched network without requiring physical dedicated lines between sites. DataSPAN gives users the bandwidth they need -- when they need it -- through dynamically allocated bandwidth-on-demand up to 1.544 megabits per second (mbps). It also allows up to 1000 data sessions to be conducted at the same time across a twisted pair connection to Northern Telecom's SuperNode using a multiplexing capability that is integrated into the switch. Finally, DataSPAN simplifies network management and reduces operational costs because additional connections can be easily made to the existing network through simple software changes. DataSPAN is more reliable than leased lines because of the redundancy built into the public network. If a trunk is lost, the network will automatically reroute the DataSPAN traffic. Local and long distance carriers will carry their users' data traffic on trunks with up to 45 mbps capacity. This high bandwidth between central offices assures customers of high reliability and high performance for their data traffic. DataSPAN complements emerging broadband data services; its architecture allows for migration to broadband access rates of 45 mbps and above. Initial applications for DataSPAN will be in the growing market for connecting local area networks (LANs). DataSPAN allows the bridging of both similar and dissimilar LANs over a wide geographic area, providing networking, for example, for branches of banks, campuses of a university, and individual offices of a business franchise. DataSPAN is a direct result of the ongoing LAN-interconnection market trial between Northern Telecom, NYNEX and Digital Equipment Corporation, announced in the spring of 1989. DataSPAN supports Open Systems Interconnect (OSI) Routers, as well as such LAN topologies as Ethernet, Token Ring, and DECnet. DataSPAN also supports the Transmission Control Protocol/Internetwork Protocol (TCP/IP) and System Network Architecture/Synchronous Data Link Control (SNA/SDLC) data communication protocols. Northern Telecom's DataSPAN service is based on International Consultative Committee for Telephone and Telegraph (CCITT) I.122 recommendations on additional packet mode data services and American National Standards Institute (ANSI) T1S1 recommendations on frame relay transport. DataSPAN is supported on the DMS SuperNode Link Peripheral Processor (LPP), an integrated peripheral that can support a variety of services, including those provided through Common Channel Signaling 7 (CCS7). Interface cards and software are the only requirements to implement DataSPAN service. DataSPAN will be available for testing by carriers in the first quarter of 1991. | Stephen Fleming | Internet: fleming@cup.portal.com | | Director, Technology Mktg. | CI$: 76354,3176 AOL: SFleming | | Northern Telecom | BIX: srfleming X.500: ??? | ------------------------------ From: Kolkka Markku Olavi Subject: Privacy and Itemized Billing (was: Re: 800 ANI) Reply-To: Kolkka Markku Olavi Organization: Finnish University and Research Network FUNET Date: Wed, 8 Aug 90 11:20:59 GMT In article <10575@accuvax.nwu.edu>, kgreer@mcnc.org (Ken Greer) writes: |> Privacy ??

I didn't get the impression that this was supposed to be funny. It turns out that there is only ONE TDD operator on duty, at least at that time, to serve the entire United States. The operator did try to place my call, but only said that it "didn't go through". No information as to why -- whether it was busy, whether the trunks were full, whether the number was wrong, nothing. (Yes, I asked. I found out afterwards that the number had the wrong country code!) Before hanging up, I asked one more question: whether there was someone I could contact to talk about providing additional staffing. The curt answer was "No one". Is it just me, or would this kind of 24-hour "service" boil anyone else's blood? If so, who SHOULD be contacted? It's not as if we TDD users could vote with our feet and go elsewhere, you know. Thanks to anyone who can provide some leads... By unfortunate coincidence, the next day I received yet another AT&T "Reach Out" promotion. Since it comes with a business-reply-mail envelope, I took the liberty of correcting some untruths on the blurb and sending it back. Not satisfying enough, however.

Heaven knows I've had several problems over the last three months with the two business lines that come into my house, and all of them were due to C&P line problems instead of my equipment. The maintenance guy shows up, plugs his headset into the jack, finds dial tone, tells me that my phone is fried ("those two-line phones do that all the time..."), and charges me $46. So I call C&P today and ask them to reverse the charge because of past experience with my business lines (I know, it's kind of weak...) The lady checked with her supervisor, and after about five minutes and confirmation of my two business numbers she came back and told me that they were going to remove the charge. Lessons: #1--When your phone dies, take a DIFFERENT phone outside to check your service jack. #2--Be persistent. :-) Questions: #1--I've had two of these damn PacTel FE 5300 phones go bad, one was bad when I bought it and this one went bad after a year. Is it even worth trying to get this one repaired? #2--If so, does anyone have a phone number? #3--If not, should I avoid 2-line phones in general when I buy a replacement?

I wrote: > I am just about to move, and my new roommate (who is also my >landlord) had another roommate some time ago who had a phone in his >own name and apparently still owes the phone company about 140 >Dollars. When I called Southern Bells customer service here in >Columbia (SC) to order my line, my order was taken, but I was told >that I could only get my installation if my roommate's former >roommate paid his debts. I was asked to post the results of my attempts to get service, and here is what has happened in the meantime: First, I tried to find my roommates ex-roommate, which turned out to be impossible (as i have learned, there is even a warrant out for him - for what I don't know - , so he disappeared). This did not make a difference to Southern Bell (I talked to an assistant manager of their SC state headquarters) who claim that anybody who lived in the place while the phone was there and had access to it is also responsible for the bills, whether the phone was in his name and he had signed for it or not (which was both not the case with my roommate), and accordingly they said they would not install a phone in ANY name at that address as long as the bill wasn't paid and my roommate were still living there. The PUC confirmed that this practice conforms to their regulations, and when I called a friend who is a lawyer he said that, legally, there really is no way to force them to install my phone line; one could only try to convince them. I finally had my supervisor at work call them (I have a summer job at the President's Office at the University of South Carolina, as network manager of their Novell net, and I am a graduate assistant during the semesters). He got them to install me a line without the ridiculously high deposit of $ 240.- that they originally wanted, in fact without any deposit. However, they said that my roommate would have to make an arrangement with them within 30 days to pay the open bill, or it would be cut off again. So, after all, my roommate will actually have to pay his ex-roommate's bill (after already having given him his share !!), although he did not sign for the account. This may be legal - at least in South Carolina -, and I understand that Southern Bell want to be paid for the service they provided, but I still don't think this way of forcing another person than the account holder to pay for it is a fair business practice; in fact, where I come from (Germany) we call it blackmail. But I guess that's just the way it is over here.

He found an empty candy-bar box and asked me if I knew what the UPC bar-code symbol was for. Trying to be helpful, I told him that it identified the manufacturer and the product for the automated cash-registers with price-lookup features. He launched into a tirade against the manufacturer of the candy, the manufacturers of cash-registers, and _me_. He was convinced that there was a secret way of encoding 666 in binary, and that Satan was hiding among the bars in the UPC symbol. Then I told him that there are no 6's in binary; only 0 and 1. He told me that he knew better; that his brother knew about these things, and that there were _hexes_ in binary. I showed him the decimal interpretation of the bar-code, printed just below the symbol, as usual. As it happened, it contained no 6's. He calmed down, a bit. About then, the train arrived! The number on the side of the first car was 7666! He refused to board the train; deciding to wait for the next one (about 30 minutes, I think). I changed my mind about 800 service from MCI. Our best-selling software product is the MoneyRoom(tm).

The two problems with detecting tones are that you are not allowed to detect a digit when none is present _AND_ you may not miss or mis-read a digit that is present no matter what the customer puts on the line (a lot of my voice-mail boards have been used in 976-xxxx applications with all sorts of music playing over voice!). This is NOT easy. The boards I am currently working on use a DSP (Digital Signal Processor [special fast computer]) to first equalize the line, apply auto gain control, and remove any correlation in the incoming audio to the outgoing program. After you do all this, then you use very good filters and a voting scheme between different methods of detecting the tone. This generally works fairly well. In low cost equipment (less than the cost of the DSP alone), a hardware chip that was designed for central office use is used. In a typical call into a central office, there is never any outgoing program, the only sounds on the line are static and the tones (your phone is supposed to turn off the mic when you press a button). If these chips hear anything other than the pure tone and dialtone, they assume you are talking and not pressing a button and disable detection. I hope this helps.

"They prefer to alter them so they will not take incoming calls, or to substitute rotary dials for touchtone. "In California, Pacific Bell blocked incoming calls to 1,000 payphones. It operates 120,000 of the total 200,000 in California. Ten percent of Seattle's payphones are limited to outgoing calls. Other cities are seeing similar efforts. "No one argues that targeting the payphones makes a difference in the total number of drug sales. But police say they can see a change in a neighborhood as soon as drug dealers lose their important tools. "In one area of Los Angeles, police say, drug sales plummeted 80% to 90% after a dozen payphones were removed. "In Washington, D.C., Chesapeake and Potomac Telephone removed 37 payphones in various neighborhoods, phones whose yearly revenue averaged well over $3,500 each. But the company lost no money by blocking incoming calls at 113 other phones. "Thomas Keane, president of the California Payphone Association, says there may be an answer in improved technology. "Payphones that can be programmed to track calls and give detailed records could aid police, says Keane. That would discourage dealers' heavyuse of the phones." -------------- So there you have one summary. Interesting to note that at some places, it seems residents have stated they wouldn't miss the payphone if it means getting rid of dealers, while we've so often assumed that lower-income areas needed the payphone for a lifeline. And, of course, establishing the "technology" to trap and trace calls from payphones is not a major project to realize, either. ------------------------------ From: woody Subject: Telephone Diverters Date: Tue, 7 Aug 90 23:44:13 EDT [The following was taken from IMEX's TELECOM echo area, which I started up for discussing Telephone/Telecommunications in the Toronto area - inquiries about IMEX or the TELECOM echo may be made to djcl@contact.uucp] From: Mark Foster Subj: Telephone diverters I recently purchased a ASAP TF 505 telephone diverter for under $200.00 this device allows for up t5 different devices to be hooked up to one incoming line. As an example you can hook up a FAX, Modem, answering machine, and two telephones to the diverter. When you call into the diverter it answers and gives the caller a false ringing, while its looks for a FAX CNG signal or a reverse modem detection (I have not tried these yet). If it detects these it then diverts the call to the modem or the fax. While it is giving the false ring, the caller (or computer) can enter up to a four digit access code and connect to one of two telephone output ports (the diverter actually regenerates a ring signal which will ring a standard 2500 tel set!!). Finally the fifth output port can have an answering machine which can give the caller instructions as to what is happening and how to enter access codes to get different connew3ctions to the five ports. In the final scenario the caller gets the beep from the t(answering machine and can leave a message. I have connected several phone to the ports and found the device to be quite acceptable. Note, if you pick up any device on any of the five ports, the rest of the ports are disabled. If anyone has one of these devices I would be interested in thier applications. Also I believe this device is available form Hello Direct under the trad name Autoswitcher. * Origin: The Super Continental (Opus 89:480/126) ------------------------------ From: woody Subject: West/East Germany Reunification Date: Tue, 7 Aug 90 23:48:46 EDT With the impending fusion of the two Germanys, it will be interesting to see how the telephone systems will work out. Would the single Germany be the only country with two country codes? Or are there plans in the works to run a single country code? If a single country code is used, it will be interesting to see how the city routing codes work out. For instance, there is a conflict in that Dresden (East Germany) has the routing +37 51, while Hannover (West) uses +49 511 (according to Toronto phone book info). The 51 and 511 city codes would conflict under a single country code. How does this get sorted out? Also, there's the matter of a single Berlin, now served by +37 2 and +49 30. Anyone have any info on the phone progress in West/East Germany? -- ------------------------------ Subject: Telebit ROM Version Reply-To: John Higdon Organization: Green Hills and Cows Date: 9 Aug 90 22:46:44 PDT (Thu) From: John Higdon This Telebit Trailblazer+ ROM thing appears to be of interest to a lot of people. There has been a lot of mail from people who are curious concerning the version of firmware that will "fix" the Sprint problem. I have just installed the firmware in the Trailblazers that talk long distance. An "ATN?" reveals: Version BC5.10A Normally I leave the speakers off to keep from going cu-coo, but a test listen reveals a tone for a couple of seconds before the traditional "bleep-blop". When the modem calls out, it inserts a few extra tones during the handshake sequence. Normally, things are rockin' here twenty-four hours a day, but naturally tonight it is completely dead. The ten or so calls that have happened in the past hour seem to have had no difficulty. I have re-enabled Sprint and will see if all this improves that situation. So far, so good, but I would have preferred to have my normal traffic beat the hell out of the modems so that I could quickly see if I should hang on to the old EPROMs. I'll report any significant developments.

Kimberlin" <0004133373@mcimail.com> Subject: A Thesis on Caller ID Organization: Telecommunications Network Architects, Safety Harbor, FL Amidst all the over Caller ID, a voice that finally made the kind of sense I needed to hear occurred on a talk program here a few days ago. As soon as I heard it expressed that way, I had to tumble in favor of Caller ID. Now, several days later, it still makes the kind of sense that tells me some of you will appreciate it, too. I have lost the source, but it was a professor of Ethics and Logic from a Pennsylvania college who made it so clear. What he said was that the argument in favor of Caller ID is the long-established principle that a visitor to your home loses all HIS rights to privacy when he comes to your premises. That is to say, you sure have a beef if somebody walks in the door of your private quarters without first Knocking (or ringing your bell!). And you have every right to demand, "Who's there?" At that point, you still have every right to decide whether or not to let them into your private space. From this it follows that unidentified telephone callers should have no more right of free access to your private premises or to the private space between your ears than does the caller at your door. As certain elements of our society have grown increasingly abusive in failing to police themselves, our legislators have tried to offer legal surcease, but the real lack of positive identification of the abusers hinders any enforcement. Example: Florida law has for some time required telemarketers to identify themselves, their organization, and their purpose within 30 seconds of opening conversation with you, and then at that point ask you if you wish to proceed. Well, I can honestly say that only a minority of the telemarketing calls I get have any identity that would let me tell the Consumer Complaints Division who the heck it was, anyway. Obviously, the illegal ones are totally unidentifiable, and with today's low loss, noise free trunks, they could be calling from Timbuctou, for all I know. And, of course, the really abusive, harassing callers are always completely unidentified. So, taken on balance, I have to agree with the professor's logic and say I will agree to give up my anonymity to sales offices when I call, just so I might get a shot at the real abusers. What I might suffer in return from sales people is trivial in my estimation to what has gone beyond a joke in telephone barbarism here in Florida. ------------------------------ From: Josh Muskovitz Subject: Gosh, There's a Lot of Acronyms Here!

The state Department of Public Utilities now gets an average of one complaint a day, and most of them are about MCI, department Commissioner Bernice McIntyre said Thursday. She said some people were apparently signed up for MCI after ``confusing statements'' from MCI solicitors that made it sound as if they were answering a questionnaire, not ordering a new type of phone service. ``It's definitely an MCI-related problem,'' McIntyre said, adding complaints started in early 1989, when the company began an aggressive marketing effort. MCI officials could not be reached for comment yesterday, but said recently that if unauthorized switching is happening, it is by mistake and represents only isolated cases. Colleen Broderick, a manager at MCI corporate headquarters in Washington, D.C., said recently that the company would not want the ill will and bad publicity caused by deliberately switching people against their wishes. McIntyre and other state utilities regulators will meet with MCI officials on Tuesday to discuss unauthorized switching, known in the industry as ``slamming.'' McIntyre will also ask the company to continue its current practice of not charging residents for any long-distance calls they made while unknowingly tied to MCI. Kathie Kneff, chief of the Federal Communications Commission's informal-complaints division, said most of the unauthorized-switching complaints she has seen in recent months from across the country are about MCI. New England Telephone, which actually makes the change in a customer's long-distance service, requires companies to obtain written authorization, but never asks to see it unless a customer complains, spokeswoman Roberta Clement has said. Rod Oehley of Hopkinton said he was called by MCI saleswomen three times in June and that each time he told them he did not want to switch. When he got a letter from MCI a month later, he said, he assumed it was just another plea and threw it out. But he learned it was actually a bill when he got a demand notice a week after that threatening to have his bill turned over to a collection agency if he did not pay up for some long-distance calls. Oehley said he called MCI, where he got a supervisor who agreed to switch his service back to AT&T but still demanded his money - until he threatened to call the Attorney General's office. ``I haven't heard from them since,'' he said. ``If I get a bill I intend to do the same thing,'' Gene Buchman of Framingham said. Buchman said he was called by an MCI solicitor twice. ``I basically told them to get lost,'' he recalled. Then, he got a letter from New England Telephone telling him his switch from AT&T to MCI had been successfully completed. ------------------------------ Date: Fri, 10 Aug 90 08:09:57 PDT From: "John R. Covert 10-Aug-1990 1055" Subject: Pinging Cellular Phones John Gilmore writes: > The US cellular telephone standard defines a way to "ping" a cellular > phone without making it ring. > If I ever get a cellular phone, this 'ping' will be one of the first > things I reprogram... No you won't. It's not a programmable feature on most phones. You see, the way incoming calls work is as follows: 1. All cell sites send "NPA NXX-XXXX, please report". This is what you called a 'ping'. 2. Your phone responds. It does not ring. 3. The cell site which hears your response sets up the call. If the call can't be set up (for any number of reasons, the most obvious being that the cell site which heard your response is out of channels), your phone never rings. Obviously, if "they" want to track your whereabouts, they just do step one, wait for your phone to respond, and do nothing else. You could only disable this feature by disabling all incoming calls. Dave Levenson writes: >If you re-program this feature, you will probably be unable to receive >incoming calls when you're roaming. Dave, you're talking about a different feature: autologin. This is the feature that causes your phone to identify itself when it travels into a new service area (new system ID). It, too, is done on request, but the request is constantly being sent along with the system id information, not as a specific request to a specific phone. If "they" are out to get you, "they" would certainly not rely on this feature to track you, since you only log in each time you cross a system ID boundary. "They" would arrange for your phone to receive incoming 'pings' but never go to the final step of starting ringing. If you don't want your location tracked, don't turn on your phone. john ------------------------------ From: woody Subject: Fastest Pulse-Dialable Number? Date: Fri, 10 Aug 90 0:15:30 EDT Here's a challenge for the TELECOM Digest readers ... what is the fastest pulse-dialable number in working order? In North America, the first choice would be +1 212 211 1111 (there seems to be a 211 prefix in 212 according to one source). Failing that, 2. +1 213 211 1111 and 3. +1 312 211 1111 (but neither 213 nor 312 seem to have a 211 prefix) Then, there are: 212 311 1111, 212 221 1111, 212 212 1111 (there does seem to be a 212-212 nxx!), 212 211 2111, 212 211 1211, 212 211 1121, and 212 211 1112. If none of those work, then there are 81 possible more combinations after that... Don't cheat by suggesting 411!! :-) [Moderator's Note: The {Chicago Tribune} classified ad-takers receive calls on 312-222-2222, which is certainly not the 'fastest' but is very quick and easy to remember. PT] ------------------------------ Date: Fri, 10 Aug 90 14:20:54 EDT From: "Dennis G. Rears (FSAC)" Subject: Basic Questions About Telephones I just had a second line installed in my house. I had to do some of the wiring which is now finished. I do have some basic questions that came out of it though: It seems as if each telephone cable contains four wires (red, green, black, and yellow). For one line only the red and green wires are used. The black and yellow wires are only used for the second line. If only one line is installed in a jack why do the yellow and black wires have to be attached? I suspect it doesn't. The modular jack that goes into the phone has four wires in it. Why is that, if only the red and green are required for service? Just in case you have a two line phone? Why is the jack that goes from the telephone headset to the telephone a different size than the jack that goes from the phone to the wall jack? Is it to idiotproof the process? Also why four wires into the headset? Does the phone itself do anything to the signals before it sends it to the headset? If the proper size jack was put on the headset could you plug that into the wall jack and recieve calls? What do the two wires (red and green or yellow and black) carry? Is one postive and negative like electrical wires? In the case of my second line I bought a double wall phone outlet. I installed the first line (R&G) to the top outline and installed the second (B&Y) line to the bottom outlet. The first line worked the second did not. The second line was live as I have a jack wired right into at the NIU. I then disconnected the wires from the NIU for the first line and reconnected them to the NIU for the second. That got the second line working. That says to me that there must be something physically wrong with the Yellow or Black wires. That seems strange to me as all four wires are in the same cable and if there was a physical break in the cable it would affect all the wires, not just one or two. Any thoughts of this? Thanks for any help. Dennis P.S.

Although my email address is in Manitoba, I live in B.C. (604-850 to be more precise, served by a GTD-5). Dialing 1-604-200/1-xxxx gives me a "Your call cannot be completed as dialed" message, which happens with every other number I try dialing with 1-604-nnx-xxxx. 1-200-0000 gives me "The number you have reached is not in service. This is a recording from the 2 2 exchange." 1-201-0000 gives me "The number you have reached is not in service. This is a recording from Mutual DS-4." However, 1-201-9999 rings and rings and rings with no intercept. Also, suffixing a # after these numbers only results in quicker ringing or intercept on the 201 numbers -- the 200 numbers are short to begin with. (end of message) ------------------ I also checked this out a bit (without actually connecting to anything other than the mentioned not-in-service recordings) and it seems that 604-200 is based in what has been referred to as the CAstle exchange (for "22"). That is the one that serves the University of British Columbia part of Vancouver. Meanwhile, 604-201 is in the big downtown exchange, the MUtual DS-4 where the 68x exchanges (among others) are found. Still, it is a bit uncertain as to what BC Tel might be up to with all this. ------------------------------ End of TELECOM Digest V10 #557 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa20811; 11 Aug 90 4:23 EDT Received: from mailinglists.eecs.nwu.edu by delta.eecs.nwu.edu id aa19563; 11 Aug 90 2:55 CDT Received: from mailinglists.eecs.nwu.edu by delta.eecs.nwu.edu id ab12844; 11 Aug 90 1:51 CDT Date: Sat, 11 Aug 90 1:33:34 CDT From: TELECOM Moderator [To]: telecom@eecs.nwu.edu Subject: TELECOM Digest V10 #558 BCC: Message-ID: <9008110133.ab16754@delta.eecs.nwu.edu> TELECOM Digest Sat, 11 Aug 90 01:32:48 CDT Volume 10 : Issue 558 Inside This Issue: Moderator: Patrick A.

In the U.S. you can claim: "I never called anybody at (201) 234 5678. They can look up the records for calls originated by the subscriber whose number is (201) 234 5678 and see if they've ever called you. That's known as "checking returns" and is routinely done in an attempt to see if your claim is reasonable. If they called you, it's less likely that you never called them.

For Bellsouth `Secrets' Date: Fri, 10 Aug 1990 21:41:07 -0400 Organization: Array Systems Computing, Inc., Toronto, Ontario, CANADA {Computerworld}, August 6, 1990, Vol. XXIV, No. 32, Page 8. Dial 1-800...for Bellsouth `Secrets' BY MICHAEL ALEXANDER CW STAFF CHICAGO --- The attorney for Craig Neidorf, a 20-year-old electronic newsletter editor, said last week that he plans to file a civil lawsuit against Bellsouth Corp. as a result of the firm's ``irresponsible'' handling of a case involving the theft of a computer text file from the firm. Federal prosecutors dismissed charges against Neidorf four days into the trial, after the prosecution witnesses conceded in cross-examination that much of the information in the text was widely available. Neidorf, the co-editor of ``Phrack,'' a newsletter for computer hackers, was accused by federal authorities of conspiring to steal and publish a text file that detailed the inner workings of Bellsouth's enhanced 911 emergency telephone system across none states in the southeast [CW, July 30]. ``What happened in this case is that the government accepted lock, stock, and barrel everything that Bellsouth told them without an independent assessment.'' said Sheldon Zenner, Neidorf's attorney. One witness, a Bellsouth service manager, acknowledged that detailed information about the inner workings of the 911 system could be purchased from Bellsouth for a nominal fee using a toll-free telephone number. A Bellcore security expert who was hired by Bellsouth to investigate intrusions into its computer systems testified that the theft of the file went unreported for nearly a year. Last week, a Bellsouth spokesman said the firm's security experts delayed reporting the theft because they were more intent on monitoring and preventing intrusions into the company's computer systems. ``There are only so much resources in the data security arena, and we felt that it was more urgent to investigate,'' he said. He also disputed assertions that the document was of little value. ``It is extremely proprietary and contained routing information on 911 calls through our none-state territory as well as entry points into the system,'' he said. A quick ending: The case unraveled after Robert Riggs, a prosecution witness who had already pleaded guilty for his role in the theft of the document, testified that he had acted alone and Neidorf had merely agreed to publish the text file in ``Phrack.'' Neidorf and his attorney agreed to a pretrial diversion, a program under which the government voluntarily dismisses the indictment but could reinstate it if Neidorf commits a similar crime withing a year. The case has stirred up national debate on the rights of computer users in the age of electronic information. The Electronic Frontier Foundation, a civil liberties group set up by Mitch Kapor, founder of Lotus Development Corp., may participate in the filing of a lawsuit against Bellsouth, and Terry Gross, an attorney at the New York law firm of Rabinowitz Boudin Standard Krinsky & Lieberman. ``The Electronic Frontier Foundation is concerned by the irresponsibility of Bellsouth of claiming from the outset that this was confidential information when it should have known that it was not,'' Gross said. ------------------------------ From: Colin Plumb Subject: Air Force Phreak Pleads Guilty Date: Fri, 10 Aug 1990 21:41:07 -0400 Organization: Array Systems Computing, Inc., Toronto, Ontario, CANADA [Moderator's Note: Also passed along from a recent issue of {Computerworld} by Colin Plumb. PT] Too much access: PENSACOLA, Fla. --- A former U.S. Air Force airman, alleged to be a member of the Legion of Doom, pleaded guilty last week in U.S. District Court to posession of at least 15 access codes with intent to defraud. Peter J. Salzman, 19, an airman at Elgin Air Force Base, used an Apple Computer, Inc.

The airman is alleged to be a member of the Legion of Doom, a group of hackers under investigation by federal and state authorities.

All Sprint rates are the same for both residence and business service, although the volume discounts migh be a bit better for businesses. They charge me 11 cents to about 19 cents per minute, depending on the time of day, whether the call is from Massachusetts or California. With the six second incremental billing, many calls are one cent, and many more are four cents!

Around here, at least in southern New Hampshire, it's mandatory. Directory assistance for anywhere in the state is 1-555-1212. And the -1212 is mandatory, too. Repair service for NET lines is listed as 1-555-1611 for residence and coin phones, 1-555-1515 for business phones (separate numbers are given for the towns with independent telcos, of course). Incidentally, three normal looking 1+ numbers are given for reaching the business office, with the notation that there is no charge for the call. This must be done with special software to remove charges to those particular numbers, since there is nothing special about them (e.g. 1-622-6233). In fact, when I call from work I call collect; if the line is answered by machine it begins with an instruction to long distance operators that all collect calls are accepted.

The original article said that the system used vocoders, not telco style A/D converters. A vocoder (voice encoder/decoder) can operate at very low data rates. The Texas Instruments Speak and Spell toy used vocoder technology (linear predictive coding) to fit digitized voice into the toy's ROM chip. A vocoder uses a model of the human vocal tract to transmit speech. It continually adjusts the model to approximate the speech input and periodically transmits the parameters to the decoder on the other end. The receiving vocoder uses the parameters to synthesize speech. Vocoders do not transmit a waveform, they transmit a description of their vocal input. This can include energy in various frequency bands, whether the speech is voiced (ah sound) or unvoiced (sh sound), dominant pitch etc. Although vocoders can be efficient, they are not without problems. At low data rates the output can sound like Donald Duck and you can confuse the vocoder by talking too fast. You may not be able to verify the identity of the caller by the sound of their voice.

A little more detail on this, so that you'll have a better understanding and can point out the ignorance that these sorts are operating under, the next time your 666 phone number attracts unwanted attention. Revelation 13:18, in describing the Antichrist (in terms that sound much like a modern totalitarian state) says: Here is wisdom. Let him who has understanding calculate the number of the beat, for the number is that ofa man; and his number is six hundred and sixty-six. In the first century A.D., there was a type of numerology called *geametria* (a corruption of the Greek word for geometry), in which the letters of the alphabet were assigned different numeric values, and the name of a person was calculated to a particular number. (You may recognize a similar superstitious practice alive today). Depending on the value of the different letters, there are a number of names that comfortably totaled "666", including the Emperor Nero's full name. (Nero was the inventor of urban renewal, though his techniques for clearing cities have been improved upon since then). (There is considerable debate among Christian theologians today whether Revelation was intended to refer to Nero's persecution of Christianity, or had a longer term significance -- certainly, putting Nero's name in the text would have caused even more difficulties for the early church than they already had). But note that the number itself wouldn't be blatant! The person who sees "666" as evidence of the Antichrist doesn't even under- stand what Rev. 13:18 refers to! Clayton E.

Even the rate varies with location. I'll go you one better: right after the tritone (that's called a SIT, right?), transmit the data DIGITALLY with a modem, the same FSK as used in Caller-ID. This is kind to machines: The tritone is the header followed immediately by the data. This is kind to humans: The tritone is loud and annoying already so a little more screaming won't hurt. FAX/modem/autodialer manufacturers should love this: If the machine recognizes the tritone and can act accordingly, you'll prevent repeated failed calls. You could automatically update the phone list when a new number is given. The retry mechanism could adapt if the line is temporarily out of service or give up if it's permanently out of service. I'd expect a CCITT definition of the command to be something like a 16 bit command followed by a variable length field.

Until just about a week ago, a caller could tell whether he was causing a call waiting beep or not by the sound of the ring. (BTW, please feel free to correct my terminology.) A normal "ring cycle" begins with two seconds of ring tone followed by three seconds of silence (and repeats). If you are the cause of a call waiting beep you came in half way thru the ring so the first ring you hear seems to cut off early. I have two lines in my home and tested this extensively and have just noticed that this behavior has stopped -- now there is no difference. I've noticed the same thing at my sister's house in Mass., 617/289-xxxx, (which I suspect is a DMS II prefix also since a call waiting beep doesn't "ker-chunk" at you like ESS does) but I didn't test it enough to be confident of the behavior. Does anyone have any more information about the disappearance of this undocumented feature? (One humorously paranoid friend ventured that it meant my phone is being tapped but that seems pretty silly to me.) Surely there will be some opinions about this feature too; I like it and miss it myself. Since I'm new to the net, I wonder if the archives have any discussions of DMS II CO equipment versus ESS and other stuff.

Townson Breakup of UK Duopoly [Christopher J.Gosnell] Re: Basic Questions About Telephones [John Higdon] Re: Basic Questions About Telephones [Dave Levenson] ---------------------------------------------------------------------- From: Christopher.J.Gosnell@stl.stc.co.uk Subject: Breakup of UK Duopoly Date: Fri, 10 Aug 90 17:42:13 BST Telecom news from Britain centers on the impending break-up of the cosy telecommunications duopoly that stifles our country and the possible introduction of local loop competition via the cable companies. (Copied from the {Independent} 7 August 1990) Telecom and Mercury to lose duopoly. - by Colin Brown Senior ministers are planning to inject more competition into the provision of telephone services in Britain by breaking the duopoly over the systems being operated bewteen British Telecom and Mercury. Cable television companies could be allowed to compete with Telecom and Mercury to provide local telephone services, but some of Margaret Thatcher's strongest supporters in the Government want to go further by opening the market to widen the national telephone network. The ministers believe the battle over the network - to be fired by an autumn government consultation paper - should be only the first step in a campaign for greater competition in public utilities, where privatisation has failed to deliver improvements. [stuff deleted about privatisation and competition] This has reinforced the view of some ministers that the telephone services should be deregulated too, allowing a free-market approach to the provision of national networks for business and domestic users. "There are a range of options for breaking the telephone duopoly, but sticking to the status quo is not an option", a government spokesman said. A ministerial battle is likely to take place over the extent to which the Telecom and Mercury duopoly is ended. Allowing cable TV companies to compete for local business would be seen as a minimal step, leading to more radical competition for national networks. BR [British Rail] and the electricity supply industries could be among those interested in competing to provide national networks of lines for the highly profitable commercial sector. The Government had hoped that breaking Telecom's monopoly would be sufficient. However, Mercury has been criticised for its slow progress and Oftel, the telephone consumer watchdog, is believed to be sympathetic to improving local services for domestic users. Ministers are reluctant to destroy the competitor they have helped to create with Mercury. No decisions have been reached, and giving more freedom to cable companies is seen as the most likely compromise. American telephone companies have invested in British cable TV companies in anticipation of being allowed to compete for local business. The demand for greater competition will be taken up next month with the publication of proposals for inclusion in the Conservative general election manifesto by the right wing No Turning Back group of Tory MPs, who include influential ministers. ---------------------- And on the inside pages: Companies lobby to cash in on telephone services boom - by Mary Fagan The prospect of the duopoly review has sparked a fierce round of lobbying on the part of the many players who want to cash in on the telecommunications boom. Representations are already being made to both the Department of Trade and Industry and the regulator, Oftel. Among the loudest voices are the cable television industry, the operators of current and future mobile telephone services, and British Rail, which for its own purposes already owns and operates one of the biggest telephone networks in the country. It is widely expected that the review will be most radical where local telephone services are concerned, as this is the sector where BT's rival, Mercury Communications, has made little impact. According to the Cable Television Association, almost all its members are interested in offering local telephone services, but they need radical changes in the regulatory system to do so. Cable television companies can offer telephone services within their franchise areas, but only as an agent of BT or Mercury. Less than half a dozen do so - all through Mercury - mainly because the revenue-sharing deals imposed by Mercury mean that it is not worth their while. The cable television companies want to become fully fledged local Public Telecommunications Operators, free to act in their own right and also with the right to link their networks to the longer distance and international networks of BT or Mercury and mobile telephone companies, or the likes of Britsh Rail. In addition, the want the right to link their adjacent local networks to form regional and even national groupings. According to Richard Woollam, the director of the Cable Television Association, the cable companies could be generating almost half of their revenues from telephone services by their tenth year in operation. Mercury has already acknowledged that margins for the cable television companies need to be better. It is believed to be allowing its cable partners to keep up to 30 per cent of revenues generated from the calls, instead of only 10 of 15 per cent in the past. British Telecom is deeply concerned that much of the renewed investment in the UK cable television industry comes from the American regional telephone companies. It is believed they are keen to cash in on the liberalised UK market, while US regulation prevents BT from taking up reciprocal opportunities on the other side of the Atlantic. Another BT concern is that it cannot provide telephone [I assume this is a misprint for television] and entertainment over its main network while the cable television industry can offer telephone services, albeit as agents. BT says that to finance the fibre-optic cabling of every home and business - which would cost up to #20 billion - it needs the revenue from television and other services such as home banking and shopping. The cable television industry argues that allowing BT such freedom could kill its fledgling industry before it gets off the ground. In any case, Mr. Woollam says BT can offer television in areas where it has a cable TV franchise, yet is selling many of its cable television investments. While most people expected the mobile cellular radio companies, such as Cellnet and Vodafone, to want a greater role and more freedom after the duopoly review, many are more surprised at the interest shown by British Rail. Last month BR launched a wholly-owned subsidiary with the right to exploit BR's nation-wide private network, which runs into every city and town in the country. The BR network is independent of BT and Mercury, whereas many private networks rely on lines leased from these two PTOs. It includes 17,000km of cable and 1,000km of microwave links, but reselling any capacity on these lines is prohibited. Peter Borer, managing director of British Rail Telecommunications, wants to expand the network, financing it through links with private sector partners. Operating at an arm's length from BR, he wants to be allowed to offer private telephone and computer networks for large companies, and to resell capacity to third parties which could also offer private networks. BR's network could also be used as a backbone to link local mobile telephone and cable television networks. Whatever the outcome, British Telecom will argue that future competitors must share its obligation to provide universal service, however remote or unprofitable the customer might be. ------------------- And now, some questions. - what is the status of local loop competition in the US ie. can a residential customer ever choose his local telco? (without moving house :-) If not, is this prohibited by law or just by Baby Bell muscle? Is ANYONE allowed to provide voice and TV services on the same line? - is there local loop competition anywhere in the world at present (assuming land-lines for the moment) - in the event of local loop competition, what should be done about universal service? Is this still a real issue in developed countries (where most everywhere is wired up already) or just a telco bellyache? Should this be a problem of private companies or should the Government be paying up for this "social service" All opinions my own, of course.

Believe it or not, all that stuff in the phone base actually serves a purpose. Besides the obvious, such as ringing and dialing, the base contains a "hybrid" circuit which takes the two wire phone line and converts it to a "four wire" circuit for the earpiece and for the tranmitter (microphone). It also provides a small DC polarizing voltage for the transmitter that is derived from the power in the phone line itself. Oh, and yes, the jacks are a different size for the purpose of idiotproofing. > What do the two wires (red and green or yellow and black) carry? Is > one postive and negative like electrical wires? Not LIKE electrical wires, they ARE electrical wires. Remember, electricity, not sound, travels through wires.

Long distance speculation of your problem would be difficult, but even if you get the line to work, you might want to replace the wiring with "twisted pair". The wire you describe, commonly called "D station wire" does not have the working pairs twisted. This almost invariably creates crosstalk between lines. Time and time again, there are people in this forum complaining about their modem line being heard in their voice line, etc., etc. The cause is usually traced to the fact that they are running two phone lines through D cable. What you want is "E wire", where the pairs are individually twisted. This often comes in three-pair and can be spotted by the colors: white/blue; white/orange; and white/green. I have E wire running all over the house, with modems, voice telephones, stations, and trunks all intermixed therein. There is no crosstalk whatsoever -- not a trace. Consider yourself lucky that there is something wrong with the D wire. Take the opportunity to pull it out and replace it with the right stuff: E wire. BTW, E wire comes "jacketed" and "unjacketed". Mine is all jacketed, but you can save a little money with unjacketed if it will run in a concealed place such as through the wall, in an attic, or under the house. John Higdon | P. O.

The extra wires are installed for ancillary services. This may include a second line, a lighted dial, a ground lead (used for selective ringing and party identification on multi-party lines). On new service, these days, they install four-pair (eight wire) cable -- it's cheaper to put in extra wires at the time of the initial installation than to put them in later, when the customer needs them. > The modular jack that goes into the phone has four wires in it.

If the proper size jack was put on > the headset could you plug that into the wall jack and recieve calls? The handset has four wires -- a two-wire circuit for the microphone, and another two-wire circuit for the receiver. Your line from the central office, as you have already noticed, has two wires. The bidirectional audio signals on these two wires are separated by a circuit called a hybrid, located in the telephone instrument. It separates the transmit and receive audio information and provides the derived four-wire path to the handset. > What do the two wires (red and green or yellow and black) carry? Is > one postive and negative like electrical wires? The two wires deliver DC power to operate your telephone set. They also carry AC voice signals. The red wire should be at ground potential, and the green wire should be at -48 volts. > In the case of my second line I bought a double wall phone outlet.

If you wired the B-Y pair to the red and green terminals on the second jack, then you probably have an open black or yellow wire in your cable. If the B-Y pair is connected to the black and yellow terminals on the second jack, connect it to the the red and green terminals on the second jack, and it will work better. It's not unusual for one wire to become defective in a multi-wire cable; that's another reason why they install extra conductors. > P.S. Does anybody know the number for ringback for 609-871-XXXX? I suggest that you try 550-XXXX, 551-XXXX, 552-XXXX etc. XXXX would be the last four digits of your telephone number. If you get a busy signal, try the next one in the sequence. If you get a dialtone after dialing, flash your switchhook. If you then get a high tone, hang up and your phone should start to ring. To stop the ringback, just answer and then hang up for at least ten seconds. Dave Levenson Voice: 908 647 0900 Fax: 908 647 6857 Westmark, Inc.

My original statement was based on observation of Pac*Bell, and as usual the practices are out of step with the real world. In the lion's share of cases, Pac*Bell makes the billing number the same as the directory number, even in cases where there are actually alternate billing arrangements. In the case of my accounts (and all those of my clients), our "Fun with ANI" number returns the directory number of the calling line even though that number is billed to a completely different (or even ficticious) number. > All the stories about the ANI identifier number being posted should > confirm this -- all those weird numbers (the BBN number from 25 years > ago, an undialable IBT number, switchboards, and various undialable > numbers) are all billing numbers for various centrex groups, PBXes, > etc. Now here's a question: what does the number readback return? Before you answer -- a short story. I happened to be going through some RJ21X positions in a client's phone room and found some lines that read back a number that was not known. I went through all of the customer's records and couldn't find the number anywhere. Four of the trunks read back this strange number and all of them were working and connected to the switch. It turns out that these lines were part of the main local group. The readback was just WRONG. Calls made on them were properly billed, and they responded properly to incoming calls. Pac*Bell corrected the readback. So what is the readback linked to? John Higdon | P. O.

On my residential two-line hunt group each line is identified by its CALLING number when I called the ANI test. Both lines are billed to the same number. Marc Kaufman (kaufman@Neon.stanford.edu) [Moderator's Note: My two lines are both BILLED on the first line. I get one bill each month, with long distance charges from the second line appended on a separate page. When I tried the ANI number just now from the second line, it read me the second, or calling number. Maybe 'billing number' is a local matter, depending on how your local telco chooses to handle it. Maybe in my case I have two 'billing numbers' with both bills shown on one monthly statement. I think there are some semantics used here to define 'billing' and 'calling' numbers.

In my office, it's like this: calls from within -- regular ringing pattern calls; from outside -- two quick rings, silence (pattern keeps repeating). [Moderator's Note: We also have this same thing on Starline, a/k/a Intellidial Service. The ringing cadence identifies the source of the call. Front door intercom service uses this as well.

However, most Hayes-compatible modems can be handed a command such as 'ATDT5551234R', and they will dial, then go into answer mode and _send_ a carrier. The box to which you refer apparantly routes incoming carrier tone to the modem. This would work fine for private use, but wouldn't be satisfactory for a BBS.

Townson Len Rose Indictment [Len Rose] ---------------------------------------------------------------------- From: Len Rose Subject: Federal Indictment Date: 10 Aug 90 00:00:42 GMT Organization: Netsys Inc., Philadelphia INDICTMENT COUNT ONE The Grand Jury for the District of Maryland charges: FACTUAL BACKGROUND 1. At all times relevant to this Indictment,American Telephone & Telegraph Company ("AT&T"), through it's subsidiary, Bell Laboratories ("Bell Labs"), manufactured and sold UNIX (a trademark of AT&T Bell Laboratories) computer systems to customers throughout the United States of America. 2. At all times relevant to this Indictment, AT&T sold computer programs ("software") designed to run on the UNIX system to those customers. This software is designed and manufactured by AT&T; some software was available to the public for purchase, other software was internal AT&T software (such as accounting and password control programs) designed to operate with the AT&T UNIX system. 3. At all times relevant to this indictment,computer hackers were individuals involved with gaining unauthorized access to computer systems by various means. These means included password scanning (use of a program that employed a large dictionary of words, which the program used in an attempt to decode the passwords of authorized computer system users), masquerading as authorized users, and use of trojan horse programs. 4. At all times relevant to this Indictment, the Legion of Doom ("LOD") was a loosely-associated group of computer hackers. Among other activities, LOD members were involved in: a. Gaining unauthorized access to computer systems for purposes of stealing computer software programs from the companies that owned the programs; b. Gaining unauthorized access to computer systems for purpose of using computer time at no charge to themselves, thereby fraudu- lently obtaining money and property from the companies that owned the computer systems; c. Gaining unauthorized access to computer systems for the purpose of stealing proprietary source code and information from the companies that owned the source code and information; d. Disseminating information about their methods of gaining unauthor- ized access to computer systems to other hackers; e. Gaining unauthorized access to computer systems for the purpose of making telephone calls at no charge to themselves,obtaining and using credit history and data for individuals other than themselves, and the like. 5. At all times relevant to this Indictment, LEONARD ROSE JR. a/k/a "Terminus", was associated with the LOD and operated his own computer system, identified as Netsys. His electronic mailing address was netsys!len COMPUTER TERMINOLOGY 6. For the purpose of this Indictment, an "assembler" is a computer program that translates computer program instructions written in assembly language (source code) into machine language executable by a computer. 7. For the purpose of this Indictment, a "compiler" is a computer program used to translate as computer program expressed in a problem oriented language (source code) into machine language executable by a computer. 8. For the purpose of this Indictment, a "computer" is an internally programmed, automatic device that performs data processing. 9. For the purpose of this Indictment, a "computer network" is a set of related,remotely connected terminals and communications facilities, including more than one computer system, with the capability of transmitting data among them through communicatiions facilities, such as telephones. 10. For the purposes of this Indictment, a "computer program" is a set of data representing coded instructions that, when executed by a computer causes the computer to process data. 11. For the purposes of this Indictment, a "computer system" is a set of related, connected, or unconnected computer equipment, devices, or software. 12. For the purposes of this Indictment,electronic mail ("e-mail") is a computerized method for sending communications and files between computers on computer networks. Persons who send and recieve e-mail are identified by a unique "mailing" address, similar to a postal address. 13. For the purposes of this Indictment a "file" is a collection of related data records treated as a unit by a computer. 14. For the purposes of thie Indictment, "hardware" is the computer and all related or attached machinery, including terminals, keyboard, disk drives, tape drives, cartridges, and other mechanical, magnetic, electrical, and electronic devices used in data processing. 15.

For the purposes of this Indictment, "software" is a set of computer programs, procedures, and associated documentation. 17. For the purposes of this Indictment,"source code" is instructions written by a computer programmer in a computer language that are used as input for a compiler, interpreter, or assembler. Access to source code permits a computer user to change the way in which a given computer system executes a program, without the knowledge of the computer system administrator. 18. For the purposes of this Indictment, "superuser privileges" (sometimes referred to as "root") are privileges on a computer system that grant the "superuser" unlimited access to the system, including the ability to change the system's programs, insert new programs, and the like. 19. For the purposes of this Indictment, a "trojan horse" is a set of computer instructions secretly inserted into a computer program so that when the program is executed, acts occur that were not intended to be performed by the program before modification. 20. For the purposes of this Indictment,"UNIX" (a trademark of AT&T Bell Laboratories) is a computer operating system designed by AT&T Bell Laboratories for use with minicomputers and small business computers, which has been widely adopted by businesses and government agencies throughout the United States. COMPUTER OPERATIONS 21. For the purposes of this Indictment, typical computer operations are as described in the following paragraphs. A computer user initiates communications with a computer system through his terminal and modem. The modem dials the access number for the computer system the user wishes to access and, after the user is connected to the system, the modem transmits and receives data to and from the computer. 22. Once the connection is established, the computer requests the user's login identification and password. If the user fails to provide valid login and password information, he cannot access the computer. 23. Once the user has gained access to the computer, he is capable of instructing the computer to execute existing programs. These programs are composed of a collection of computer files stored in the computer's memory. The commands that make up each file and, in turn, each program, are source code. Users who have source code are able to see all of the commands that make up a particular program. They can change these commands, causing the computer to perform tasks that the author of the program did not intend. 24. The user may also copy certain files or programs from the computer he has accessed; if the user is unauthorized, this procedure allows the user to obtain information that is not otherwise available to him. 25. In addition, once a user has accessed a computer, he may use it's network connections to gain access to other computers. Gaining access from one computer to another permits a user to conceal his location because login information on the second computer will reflect only that the first computer accessed the second computer. 26. If a user has superuser privileges, he may add, replace, or modify existing programs in the computer system. The user performs these tasks by "going root"; that is, by entering a superuser password and instructing the computer to make systemic changes. 27. On or about January 13, 1989, in the State and District of Maryland, and elsewhere, LEONARD ROSE JR. a/k/a Terminus did knowingly, willfully, intentionally, and with intent to defraud, traffic in (that is, transfer, and otherwise dispose of to another, and obtain control of with intent to transfer and dispose of) information through which a computer may be accessed without authorization, to wit: a trojan horse program designed to collect superuser passwords, and by such conduct affected interstate commerce. COUNT TWO And the Grand Jury for the District of Maryland further charges: 1. Paragraphs 1 through 26 of Count One are incorporated by reference, as if fully set forth. 2. On or about January 9,1990, in the State and District of Maryland, and elsewhere, LEONARD ROSE JR. a/k/a/ Terminus did knowingly, willfully, intentionally, and with intent to defraud, traffic in (that is, transfer, and otherwise dispose of to another, and obtain control of with intent to transfer and dispose of) information through which a computer may be accessed without authorization, to wit: a trojan horse login program, and by such conduct affected interstate commerce. COUNT THREE And the Grand Jury for the District of Maryland further charges: 1. Paragraphs 1 through 26 of Count One are incorporated by reference, as if fully set forth. 2. That on or about May 13, 1988 in the State and District of Maryland, and elsewhere, LEONARD ROSE JR. a/k/a/ Terminus did cause to be transported, transmitted, and transformed in interstate commerce goods, wares, and merchandise of the value of $5000 or more, to wit: computer source code that was confidential, proprietary information of AT&T, knowing the same to have been stolen, converted, and taken by fraud. COUNT FOUR And the Grand Jury for the District of Maryland further charges: 1. Paragraphs 1 through 26 of Count One are incorporated by reference, as if fully set forth. 2. That on or about January 15, 1989 in the State and District of Maryland, and elsewhere, LEONARD ROSE JR. a/k/a/ Terminus did cause to be transported, transmitted, and transformed in interstate commerce goods, wares,and merchandise of the value of $5000 or more, to wit: computer source code that was confidential, proprietary information of AT&T, knowing the same to have been stolen, converted, and taken by fraud. COUNT FIVE And the Grand Jury for the District of Maryland further charges: 1. Paragraphs 1 through 26 of Count One are incorporated by reference, as if fully set forth. 2. That on or about January 8, 1990 in the State and District of Maryland, and elsewhere, LEONARD ROSE JR. a/k/a/ Terminus did cause to be transported, transmitted, and transformed in interstate commerce goods, wares, and merchandise of the value of $5000 or more, to wit: computer source code that was confidential, proprietary information of AT&T, knowing the same to have been stolen, converted, and taken by fraud. ____________________ Breckinridge L. Wilcox [Moderator's Note: Mr. Wilcox is probably the foreperson of the Grand Jury. The five counts above, according to Mr. Rose, represent the various occassions on which he is alleged to have transferred a 'password-trapping' program to other individuals, including Craig Neidorf. If my understanding of the allegations is correct, modifications to the source code causing passwords entered by users using the 'su' command to be retained in a separate file for review by unauthorized persons was transmitted. I believe Mr. Neidorf then printed this information in his publication {Phrack}. It is not known to what extent this modification was installed or implemented. Mr. Rose said to me he does not know of anyone 'who actually used or installed' this modification. He said he wrote it legitimatly for testing and diagnostic purposes for his own use at his site and for legitimate clients. He said he can't help it if it fell into the hands of persons who would abuse or misuse his work. Mr. Rose said to me he is destitute at this time due to the financial burden of obtaining legal counsel and being without the tools (his computing machinery and related stuff) he needs to be employed. His trial has been adjourned until sometime early in 1991 at the court's motion, and this additional delay will cause him more financial hardship. He believes this delay was given by the court in retaliation for motions entered by his attorney asking the judge to recuse himself. He said he had been offered 'deals' by the government, including pleading guilty to one count, receiving as punishment several months in the custody of the Attorney General, followed by perhaps a year of federal probation. His equipment would be returned as part of the deal. If this were his choice -- that the matter be adjudicated in conference between the government, his attorney and the court -- resolution could come in a short time. If he prefers, the matter can go to trial, and he can take his chances on complete acquittal, or being found guilty on one or more of the charges against him, followed by imposition of punishment as detirmined by the court at that time. Mr. Rose has received advice from several quarters on this important issue, both for and against cutting deals. He said 'people at the Electronic Frontier Foundation refuse to return his phone calls', but that others, including a prominent person at the Free Software Foundation have encouraged him to hold out for trial and acquittal. In either scenario, Mr. Rose's prior state conviction several months ago involving computer equipment stolen from the warehouse found in his possession does not enhance his ability to cut deals to his liking. It should be remembered that under the Constitution of the United States, Len Rose must be considered innocent of the latest charges against him until his guilt is proven in court, or based on his plea of guilty the court finds him guilty.

As you may know Argentina is in the midst of a profound economic crisis. As a consequence of this there has been a severe reduction in the governmental budget. Unless special attention is paid to science we believe that meager salaries combined with lack of funding will lead to the shut down of our laboratories before there is any improvement in the economic situation. The following example provides a glimpse of our economic situation: a scientist holding the highest available position receives a monthly salary of US$ 300 (United States dollars three hundred). On the other end of the scale a junior scientist starting his/her career is paid a salary of about US$ 100. These sums are far lower than those required for subsistence-level feeding and education for an average family. If you are willing to help us, please write a letter in your own words or use the attached letter as a model and send it via air mail to: Sr. Presidente de la Republica Argentina Dr. Carlos Saul Menem Casa de Gobierno, Balcarce 50, 1064 Buenos Aires, ARGENTINA To expand the chain please send ten copies of this letter to your friends. MODEL LETTER Sr. Presidente de la Republica Argentina Dr. Carlos Saul Menem Casa de Gobierno, Balcarce 50 1064 Buenos Aires, ARGENTINA Dear Mr. President, I am writing you to call your attention to the present situation of scientific and technological research in Argentina. Argentine scientists will not be able to endure for a long time the present situation in which the lack of funds to support research is combined with the incredibly low salaries paid to them. Such situation will soon lead to a sharp increase in the exodus, which has already started, of qualified people and hence to the irreversible damage to your national scientific and technological research system whose quality is recognized and respected by the international scientific community. This would be a tragedy for Argentina's cultural and technological development which would require years to repair. With all due respect, Mr. President, I urge you to take actions to reverse this sad situation. This may help to change the negative image that the international community has about this aspect of your administration. Sincerely yours (Signature, name and academic position) Other addresses to which correspondence may be forwarded: Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET) Avenida Rivadavia 1917, 1033 Buenos Aires, ARGENTINA Secretaria de Ciencia y Tecnica (SECyT) Avenida Cordoba 831, 1054 Buenos Aires, ARGENTINA New Haven, 6 de Agosto de 1990 Estimados todos: Esta es la primera vez que me dirijo a todos ustedes por medio de la red.

Well, I have to say "thank you" to Nigel for raising a question near and dear to my heart that caused an excursion back to a comfortable past career. I was prompted to answer the question in part from my personal library and experience, but also to get on the phone to have a very pleasant chat with my old Almer Mater of international shortwave radio, WOM at Ft. Lauderdale, FL. Here's an attempt at summarizing a lot of detail: While yes, it is true that shore telegraph stations are retiring from the airwaves, and significant shifts are occurring. Maritime Mobile Radio using Medium Frequency and High Frequency radio is, believe it or not, still growing, and MARISAT/INMARSAT are far from supplanting it. And this in spite of some incursions by cellular radio as well. First, we must make it clear. Until or unless there comes to pass a global form of radiotelephony like Motorola's IRIDIUM proposal, there are vast stretches of ocean reached only by HF radio or INMARSAT. My phone inquiry to WOM found them very aware of these developments, revealing they found that while some ships, mostly supertankers, bought into INMARSAT, the $10 (U.S.) per minute rate compares poorly with the $4.90 per minute of HF radiotelephone, especially because INMARSAT bills from the moment of connection while High Seas (HF) radio makes all calls person-to-person and bills only when the conversation starts. Apparently shipping companies come to this conclusion when they get their bills, and find that a call to the ship's steward for a one-minute talk results in a $100 charge while they wait on hold for him to be paged to the satellite phone! What the WOM folk knew was that satellite-equipped ships use INMARSAT for hard-copy communications, running not only Telex but even PC's at 64 kilobits off the ship. That's what's killing the shore telegraph stations. They're not all dead however, just shrinking back to meet reduced demand. For that structural background Nigel asked about, shore radiotelegraph stations in the U.S. grew before there could be any structure to their sub-industry, mostly as "company" stations. For example, the origin of TRT Telecommunications, today in Washington, DC, was as a 1912 ship and shore radiotelegraph operation of the United Fruit Company in Boston, using 1912's "highest tech" to direct shiploads of bananas to the best markets while enroute. That expanded to using radiotelegraph to the plantations in Central America, and that expanded to TRT becoming the international telegraph (and sometimes international telephone) company of much of Central America; the entity on the other end of AT&T's point-to-point HF radiotelephone from the U.S. RCA, of course, made shipboard radios for many American-flag ships (remember that David Sarnoff, builder of the RCA empire, was first a Marconi Corp. ship's radio telegrapher.); the result was RCA building a string of shore telegraph stations for its customers. And, the RCA shore stations operated radioteletype as a service to promote sales of shipboard RTTY gear. ITT got into the act by owning Mackay Marine, which competed with RCA for maritime radio equipment and services, and so had a string of stations, too. There was no territorial or service monopoly. In fact, just the opposite seems to have happened, and caused some significant words in the (U.S.) Communications Act of 1934, to the effect that (sic) radio stations for public correspondence must accept communications and traffic from any mobile station, because the "company" stations had, in fact, refused to answer calls from (even distressed) ships of other companies. What developed from that point was an interesting form of competition of many years' duration. The shore stations did compete with attempts at camraderie and service in ways only telegraphers could understand. Imagine if you can, an unseen, unheard person on shore exuding warmth and personality via a telegraph key ... and they did. Despite the shrinkage of the number of radiotelegraph shore stations, the remaining ones seem to be enjoying growth by picking up the slack. For example, WPD at Tampa, FL seems to still be going strong, independently owned as it has always been, handing its traffic off as domestic telegram and Telex messages (that have now largely become E-Mail with PCs). One of the other "company stations" that never operated maritime traffic, the Trans-Liberia Radiotelegraph Company (built by Firestone solely to communicate with its plantations in Liberia) seems also to still be in business from Akron, Ohio ... but has been off HF radio for many years, and is now largely a message center with a couple of PCs ... but you could, if you wanted to, send a telegram to Liberia via Trans-Liberia! As to the telephone business, INMARSAT, as noted, may have made some market, but it seems to be rather insignificant to WOM and it companions. Their market still grows. AT&T has operations at WOO near New York, WOM near Miami and KMI near San Francisco. The single most significant part of the traffic is cruise ships, that enjoy handsome profit margins on phone calls to shore for passengers. It's known that one cruise line tells passengers they are on satellite, and charges $30 per minute, while putting the calls on HF radio (yes, HF can sound mighty good, running SSB radio with Lincompex) where the shore station charges $4.90 less a $1 "commission" to the ship! The surge of technology has helped, with $800 SSB transceivers, so that small ships and private yachts get on HF radiotelephone, too ... not wanting to pay the price of a satellite shipboard station and then the per-minute rates. They have fueled the surge in minutes, along with ... of all things ... aircraft! The WOM folks handle a fair amount of calls for private aircraft, notably some Venezuelan oil company planes that travel from South America across the Atlantic and Africa to Saudi Arabia. Some few "hep" international airline captains have even found their HF transceiver can get them a phone call to home while crossing the Pacific at 35,000 feet! The result is that WOM alone of the three AT&T stations is handling about 700 revenue-producing calls a day. And, the traffic of the one privately-owned U.S. station for international telephone traffic, WLO at Mobile, Alabama seems to also be healthy. The standards bodies seem to sense this growth, for in 1991, the channel assignments for HF maritime radiotelephone use will be restructured again, with narrower channel widths (2.8 kHz) to create more channels. As mentioned earlier, the sub-industry is restructuring, in some cases with technology old-timers could never comprehend. A major change has been and continues toward automating and reducing overheads by consolidation. As I write this, work is underway to consolidate the control point for NY's WOO in the WOM control room at Fort Lauderdale. Similarly, the local telcos who always ran the medium-frequency (2 mHz) Coastal Harbor operations abandoned them with demonopolization, and WOM took over Miami, Jacksonville and Charleston, SC, running the whole works with the WOM callsign and 10KW transmitters, while the receivers along the shoreline are wired to Fort Lauderdale. The communications technology behind it is in some ways awesome, in others what we should simply expect. The WOM location in Ft. Lauderdale is 50 miles from its transmitters in Pennsuco, west of Miami, while the actual landline telephone operators all the ships speak to are in Pittsburgh, Pennsylvania! Not such a feat when you find out that the building is also AT&T's fiber POP for Ft. Lauderdale and WOM enjoys its own whole fiber route direct to Pittsburgh! Meantime, control of the transmitters is by PC messages shot around AT&T's packet data net to turn a transmitter on or off or change its antenna ... no clunky old "control circuits" at all; instead messages from a 3B1 UNIX machine (yes, they are planning to get 3B2s) that go on a packet network to be read by similar machines with control interfaces at Pennsuco (and soon, Manahawkin, NJ for WOO ... with KMI's Dixon, CA transmitters a likely addition someday). And, HF radiotelephone even has its disaster function. During Hurricane Hugo's trip through the Virgin Islands and Puerto Rico last year, the first restoration of telephone connections to the U.S. was from ship radiotelephones there to WOM for several days. Of course, the world gets little news from the networks about such undergirdings of telecommunications. If people had wanted, they could have as well made phone calls into the U.S. telephone network (and thus the world) via WOM in the Mexico City earthquakes. FCC rules do permit doing ANYTHING with a radio transmitter if it is for the safety of life and property ... but that doesn't mean calling to see if Uncle Fred's attic window got broken, it means serious PUBLIC safety. Oh, the cellular incursion. Yes, it's there, but again not that significant to a growing market. First, cellular of course, reaches only incidentally a few miles offshore. There are automated VHF marine-band dialable shore stations that do reach seaward, but perhaps only 50 miles offshore. Run by a private company in Hollywood, FL, these similarly are remote controlled from that city, even though they range along the whole coast. And, in the Bahamas Islands group there are reported to be two cellular companies among the islands, Cruise-Phone and Boat-Phone. They serve an obvious purpose for boaters sailing among the thousands of Bahamas Islands, but only there. Growth seems apparent in other areas, too. St.Thomas in the Virgin Islands has HF voice station WAH that is growing, as do several of the other nations' Caribbean islands ... French, Dutch, English and so on. And, of course, around the world, there are the established stations of many nations. The "territorial monopoly" is rather interesting when the Laws of Physics interfere. It's very difficult for nations to legislate what shore station a vessel calls ... even though some do force it economically, witness the Cuban shore stations with their own and Russian ships, plying the same waters, but never getting on the channels of the American stations, even though they easily can. So, I hope this is the kind of response Nigel wanted. It's a peek into another galaxy of telecomm that most people don't even know exists or thinks is dead is the kind of response you wanted. From the figures I got today, it's another telecom business that grosses at least $15 million a year, and perhaps several times that. And, since this peek got so long, here's a vignette learned yesterday from the WOM Technical Operator I chatted with. We were comparing stories about handling REAL emergency traffic, as anyone who has done that job has done, as he gave me a real side-splitter. Seems he worked the third shift for a couple of years, and in the darkest hours of night, traffic tends to be nearly zero. However, one night at 3 AM, he heard a whispering voice on the speaker of his calling receiver saying, "Hello? Is anybody on here?" He lit up a transmitter and answered, whereupon the caller identifed himself as a ship and said, "We are under attack by the Indians!" What? A ship at sea under Indian attack? What it turned out to be was s small freighter that had run aground on remote shoreline of Nicaragua, and the natives were boarding the ship and stealing everything in sight! Not daunted by this at all, the WOM T.O. called the U.S. Coast Guard District Office to find out what support was available, and within a short time the Nicaraguan National Guard was dispatched to quell the Indian uprising. If you think, "Having that job must be a ball," you're absolutely right. Many is the time I've thought I should have stayed there. Pity it's only one that employs a handful of people. Oh, it's not a "secret" place although not in tour books. Located at the corner of State Road 7 and Sunrise Boulevard in Fort Lauderdale, just look up AT&T Company and give 'em a ring if you want to visit! [Moderator's Note: *Thank you* for a very interesting and informative article. I'm sure you are correct that this is a form of telecommunications very few people know anything about.

Normally, a federal indictment will state under each or charge the specific statute under which the particular offense has been committed. Lest someone read into this an accusation that Len Rose edited his indictment for some particular purpose, let me add that it is often easy to overlook the statutory references, which typically appear at the bottom of each page, and which often look like pro-forma additions. But without the statutory references, it is unclear which statutes Rose is alleged to have violated. It seems certain that 18 USC 1343 (wire fraud) and 18 USC 2314 (interstate transportation of stolen property) are two of the statutes; it is unclear, however, whether the government is also prosecuting Rose under 18 USC 1030 (use of computers to defraud) or 18 USC 371 (conspiracy). The particular statutes under which Rose is being prosecuted will dictate many of the issues that will be litigated if he goes to trial. My personal favorite of the counts is Count Two: >And the Grand Jury for the District of Maryland further charges: >1. Paragraphs 1 through 26 of Count One are incorporated by reference, >as if fully set forth. >2. On or about January 9,1990, in the State and District of Maryland, >and elsewhere, > LEONARD ROSE JR. a/k/a/ Terminus >did knowingly, willfully, intentionally, and with intent to defraud, >traffic in (that is, transfer, and otherwise dispose of to another, >and obtain control of with intent to transfer and dispose of) >information through which a computer may be accessed without >authorization, to wit: a trojan horse login program, and by such >conduct affected interstate commerce. I know of no federal statute that outlaws "trafficking in" information "through which a computer may be accessed without authorization," absent some allegation that the information was proprietary and stolen. One wonders whether this count is meant to refer to Rose's authoring a password-recording modification to AT&T system software. Our Moderator offers what seems to me to be a correct interpretation of at least one of the counts: >If my understanding of the allegations is correct, >modifications to the source code causing passwords entered by users >using the 'su' command to be retained in a separate file for review by >unauthorized persons was transmitted. I believe Mr. Neidorf then >printed this information in his publication {Phrack}. Assuming this interpretation is correct, it is unclear whether Rose broke the law in this action, unless the federal government has proof that Rose's actions were part of a conspiracy to defraud AT&T or one of the Bells. (That's why it's important to determine whether a conspiracy is being charged here.) In conspiracy prosecutions, an otherwise-legal act may make a defendant liable under the conspiracy statute if that legal act was in furtherance of the conspiracy.

His argument falls apart on close exami- nation. a) He pulls at the emotional heartstrings of "privacy in your own home" to try to argue for Caller-ID. However, virtually all the complaints about invasions of privacy have had to do with potential abuses by BUSINESSES. Clear black-and-white dicotomies - public vs. private places - are nice for arguments, but have little to do with reality. When I go into a store, I give up very few of my privacy rights. A store is not someone's home: It's a place of business, and falls somewhere between public and private. For example, you can if you wish choose to refuse to allow black people into your home. You cannot choose to bar them from your store. By offering services to the public, you have given up certain privacy rights. Conversely, I as a member of the public retain many more of my privacy rights in your store than I do in your home. In particular, you can certainly demand to know who I am before allowing me into your home. You cannot demand identification as a pre-condition for allowing me into your store. All you can get from this argument is that NON-BUSINESS lines have a right to receive Caller-ID. For all their talk about protecting people's privacy, the telco's REALLY want to sell Caller-ID to, you got it, businesses. That's where the money is. b) Even if we restrict ourselves to private homes and non-business lines, his argument is weak. I have the right to knock on your front door. You don't have to let me in unless I identify myself, but you can't stop me from knock- ing. I don't believe a "no solicitors" sign has any legal weight. (A "no trespassing" sign MIGHT - although I can't enforce it selectively, letting some people in without invitation and choosing to go after others.) I'll argue that the knock on the door and the ring of the telephone are equal invasions of privacy. In each case, you have the right to ask for identifica- tion. In each case, I can refuse to provide it - in which case you can close the door or hang up the phone. That's as far as your rights go if I refuse to identify myself. In telephony terms, this means that I should have the right to send my ID or not; and you have the right to receive it, and refuse to answer if I didn't send it. (A better analogy - and a better Caller-ID system, though perhaps technically impractical - would be a button or setting on your phone that explicity asked for Caller-ID. I would receive a notification of the request and could choose to allow my identification to be sent, or not. This would be the electronic analogue of your asking for my name - except that I would be unable to lie about it.) BTW, the analogy of the "no solicitors" sign is your ability to say that you don't want any telemarketing calls. In the past, you've had no way to enforce this. The bill just passed by Congress, requiring that telemarketers respect a list of "no calls" numbers, provides exactly this ability.

This information might be wrong, but I seem to recall reading that the tapes were not recorded from cellular calls but rather conversations that the minister made through a mobile telephone that works something like marine radio ("AutoTel", I think). There are a small number of channels (six?) that are accessible throughout the province and I suppose Smith wanted to be able to stay in touch even when he was visiting some backwater whistlestop. As far as I know, the individual who admitted to making the tapes was nothing more than a news-gathering type creature who had a grudge, a scanner, and a recorder. The sins, if any, that the A-G committed are, in my opinion, exaggerated (although government drones have yet to speak.) To me, his most criminal act as a politician was using what amounted to a CB radio and thinking no one else would listen in. Incidentally, as part of the fallout, last I heard is that Smith is being sued by some lawyer who was maligned in a taped "private" conversation between the A-G and his deputy. My guess is that the suit will get laughed out of court; or have defamation cases been won elsewhere under such odd circumstances? jonathan@jspc.wimsey.bc.ca ------------------------------ From: John Nagle Subject: Re: Pinging Cellular Phones Date: 11 Aug 90 19:37:47 GMT >followed by call setups, you could determine if any user location >activity is taking place.

Medina, Ohio USA +1 216 723-3000 Date: Sat, 11 Aug 90 00:00:00 GMT OK since we are on the 666 subject again, here's a bit of info and a comment I never got around to last time: 216-666 is the Montrose, Ohio exchange. There are several reasons to believe there may be some hellish connotation here: - It is a GTE Ohio exchange (That ought to prove it as far as John Higdon is concerned) - It is a GTE Automatic Electric No. 2 EAX office. (OK, maybe its just telepone purgatory, then) - Montrose is a suburb of Akron, Ohio (almost hell to New York types) - My in-laws live in this exchange (and have for 30 years....I will risk no other personal comment) Another item: - The Montrose CO was knocked out of service for half a day by a direct lightning strike on the power pole beside the building. The generator in the CO could not help because the breakers for the battery chargers were all tripped. When the CO batteries discharged, things just ground to a halt. The CO was unmanned for the weekend, and GTE did not dispatch because the alarms showed a power failure with the generator running OK. Help was send only when the office went "no tone"...with three different municipalities police dispatch centers in it. Repair was slowed by the need to replace the damamged breakers, and no supply houses were open on Sunday. Needless to say, GTE was called on the carpet for this one... (The PUCO never was told the whole story, BTW) A few other comments: Montrose 1000 cycle test tone is 216-666-1212 ... and many people often dial it by mistake for 216-555-1212 ... I remember some AT&T toll reports we got when I worked for GTE back in '70 that noted this..and suggested GTE change the number (which they would never do). My in-laws number is one digit different from the 1000 cycle number, and they have gotten a few odd phone calls due to this. My father in law is a retired police chief, and when I worked for GTE he was active. I traced a few of these bad calls for him and traced some to an Ohio Bell test desk in Akron Blackstone exchange. An automatic trunk routiner had been programmed with the 666-1212 number, but a bad thumbwheel had caused one digit to work erratically ... thus causing the problem. My father-in-law suggested he could personally impound the test board supervisor's car if the problem was not promptly repaired ... an interesting solution to telephone equipment repair delays, IMHO. It never came to that. Ohio Bell repaired their unit promptly once the problem was explained to them (and they decided they could believe a lowly GTE person ... I had to tell them I was ex-Bell to get them to listen). Anyhow, we have our share of fundmentalist churches and preachers here, perhaps they should all move to the 216-666 exchange to try and help solve these problems ...

The untwisted wire described is what I have always called "quad station wire", I have no idea what the real name is, but I don't think "D station wire" is right. My AT&T catalog lists what they call DIW, "D Inside Wire" which is indeed twisted pairs. You can get it in various pair counts from as few as 2 or 3 up to, I think, about 6 or 8. The most common variety I've seen is 4 pair. Unlike common 25 pair cables, the pairs are packed loosly in the PVC sheath, making it very flexible. It sounds exactly like what John is describing as "E wire". I am willing to defer to hard evidence to the contrary, but I have trouble believing you could get any appreciable amount of crosstalk between two properly balanced circuits (even if not using twisted pairs) over the, say, 100 feet of wire you might find in a common residential installation. My trailblazer coexists just fine with my voice line over plain old quad wire, running what I would guess is about 60 feet in the same quad.

I have seen it happen over lengths of as little as 25 feet. Remember that crosstalk rejection between circuits depends on the electrostatic and electromagnetic cancellation caused by the two conductors of the circuit. If you have conductors randomly interspersed within a cable and if an individual leg of one circuit travel for some appreciable distance with the leg of another, then your "properly balanced circuits" might just as well be unbalanced. > My trailblazer coexists just fine with my voice line over plain old quad > wire, running what I would guess is about 60 feet in the same quad.

That's very nice. Random chance works in mysterious ways. The original poster indicated that there was some hard problem with his quad. Rather than nurse it back to health or replace it with more quad, my suggestion was to replace it with the "right stuff". I have a number of "cheap and dirty" tricks that I use and get away with, but don't don't usually advocate them in a public forum. The "I know it's wrong in theory, but it works fine for me" principle can cause people grief. Once again, I don't recommend using quad (or any non-twisted pair) cable for multiple lines.

The nearest National Weather Service transmitter is on Puerto Rico, and doesn't quite reach St. Thomas, let alone the other islands. So, on a regular schedule, VI Radio (who, with the tallest mast on St Thomas, apparantly can hear NWS Puerto Rico) rebroadcasts the NWS weather reports. They can be heard all over the USVI and the BVI on VHF 16, and even further on HF. Everybody tunes in at 1000 to hear the list of waiting traffic and get the weather. They also don't seem to mind being the universal ping object, answering requests for radio checks from anybody within range. There seem to be more VHF radios in the Virgins than telephones. Every business that has anything to do with boats (i.e. most of them) stand by on 16 (or some other channel which they advertise next to their phone number) waiting to take dinner reservations, schedule diving trips, or anything you might normally pick up a phone to do. We once had to call our charter company to arrange for some spare parts. We couldn't get them on VHF (probably their little antenna was below our horizon) so we called VI Radio and had them place a phone call. When they still didn't answer, we kept VI Radio on the line for what seemed like for ever, trying different numbers (in conditions under which we could barely hear each other) until they finally got through to somebody. Never once did they suggest that the amount of their time we were taking up (for a non-emergency), compared to what they must have been able to charge for the phone call, certainly worked out to a substantial loss for them.

I know of no >non-fax modems that would work with the device described above. All fax machines are supposed to generate calling tone when the machine dials. If an autodialing fax machine doesn't generate calling tone (CNG), it is in violation of the T.30 recommendation for fax machines. Since there are some data modems that are V.25bis or V.25 compliant, there is a small chance that the "telephone diverter" in question is designed to use both Fax CNG and modem CNG as a means to route calls. However, the device in question would probably not work to well if it is looking for modem calling tone, as very few modems in the U.S. have the ability to generate it.

Rather than enter the whole thing again here, I have forwarded the more detailed version direct to the Telecom Archives, to the section entitled 'telecom.security.issues', where it is filed with other related cases and commentaries. For your reference, here are the specific cites: The five counts are almost identical in wording, and each refers to: 18 USC S 1030 (a) (6) - Computer Fraud. 18 USC S 2314 - Transportation of Stolen Property 18 USC S 2 - Aiding and Abetting.

In 1989, Len was indicted for stealing computer equipment under circumstances that, while in no way acceptable, where not simply rip-off. Len has not yet been convicted for that offense. He has been offered a plea arrangement which he plans to accept later this month. In my (and others') communications with him, he has never denied that act, he has never condoned it, he has never in anyway tried to justify it. His attitude has been one of accepting responsibility for it and facing the consequences. He has repeatedly expressed shame and remorse for it, but recognizes that it has been done. He cannot undo his action, he can only live with it. The 1989 incident is totally unrelated to the current one in which he is charged with computer fraud and transportation of stolen "property." Continually alluding to the past incident diverts attention from two issues raised in the current case. First, as a "Len Rose" issue, the charges seem to exceed what he is alleged to have done. Information beginning to seep in from related details in the Neidorf trial, from documents known to be evidence in Len's case, and from individuals involved in the case, produces a gnawing feeling of deja vous all over again. Those who read the recent version of the indictment in TELECOM Digest noticed that the violated statutes were omitted. A source who possessed the original copy read the statues in a telephone conversation: Counts 1 and 2: Title 18 Sect. 1030(a)(6) and 18 Sect. 2. Counts 3, 4, and 5: Title 18 Sect. 2314 and Title 18 Sect 2. We will confirm this when we obtain a copy of the original later in the week. The second issue is *NOT* a Len Rose issue and could affect many of us who use a modem. Len is not being charged with theft, but with fraud (for writing a trojan horse program -- he is accused only of writing it, not of using it illegally), for writing a program to capture passwords, and for sending these to another state. Modifications in the trojan horse program are alleged to be on proprietary source code, which was one fraction of a larger program. It should be remembered that in the Neidorf trial, the concept of "proprietary information" was grossly abused by BellSouth. Whether that is the case here remains to be seen, but the apparent similarities between the two cases should cause concern to all of us. Anybody who hangs out on Bulletin Boards or who is familiar with archives on other nets is aware that there are may similar programs in the public domain. If Len is found guilty, what is the status of anybody who possesses or sends a program that crypts/encrypts passwords, or who writes such programs in, for example, California, as a consequence of some legitimate need, then sends them to Michigan? This second issue brings us back to the issue of law-enforcement creativity in distorting law for questionable prosecution. We have seen in the Neidorf case that prosecutors, despite overwhelming evidence, can pursue prosecutions that do not belong in the courts. Subsequent evidence could prove us wrong, but to date, we have neither seen nor heard even the suggestion of any evidence that indicates that U.S. v. Leonard Rose is any different than U.S. v. Craig Neidorf. To raise the issue of the 1989 offense distorts these issues. The outcome of the current case should be on the current issues. If Len is being unjustly prosecuted, it is wrong to raise his 1989 behavior as a way of mitigating this injustice. Let's focus on the current issues avoid red herrings. [Moderator's Note: You got the same copy of the indictment I received. And your note to me indicated you also had to edit the word 'Amerika'. The legal cites were included in a Digest Sunday afternoon. On the subject of Red Herrings, you seem to know quite a bit about how they work. While his previous difficulty will not be considered as evidence in the current matter, it will be considered in any pre-sentence social investigation the court relies upon when imposing punishment. It is not totally irrelevant to the present case.

Then add (also at no charge) the ability to turn on (or off) caller ID for a single call, much as someone uses "*70" to turn off Call Waiting. I would, normally, leave caller-id off, but if a friend was paranoid about getting calls from strangers, I could turn it back on. Also, does anyone out there object to the phone company charging for the "service" that allows you to report that the last call received as a crank call?

He writes: >Your ethicist is demonstrating how easy it is to get the answer you >want if you just can choose the question. His argument falls apart on >close examination.... However, virtually all the complaints about >invasions of privacy have had to do with potential abuses by BUSINESSES. This is simply not the case. Most complaints about Caller ID stem from the right of callers to make anonymous phone calls, not the right of being spared from telephone solicitations from overzealous salespeople. Several cases have been effectively raised by Caller ID opponents to stress the need for anonymity: a) A psychologist calling patients from her home, b) A woman calling her husband from a special shelter for battered housewives, c) Individuals who may be "scared away" from calling certain hotlines (AIDS, drug abuse, crime tips, etc.). Many have argued that Caller ID would inevitably result in an increase in telephone solicitations as businesses compile more "telephone lists" of potential customers, and share such lists with other businesses. There is some validity to this argument, but one should consider that telemarketers have access to such lists today, and that Caller ID by itself, wouldn't add much information (I have an unlisted number and I do get several solicitations daily). It is important to recognize that this is essentially a telemarketing problem and not a Caller ID problem. Proper regulation of telemarketing practices is the best way to limit the excesses of telemarketing. As Jerry noted, Congress has just passed a law that would prohibit telemarketers from making computer-generated calls to individuals who have listed their telephone numbers in a special database. Jerry goes on to say: >the telco's REALLY want to sell Caller-ID to, you got it, businesses. >That's where the money is. I don't know on what basis this assertion is made. Caller ID is viewed today by telephone companies as a residential service and has been aggressively marketed it as such. Bell Atlantic indicate that 94% of their Caller ID subscribers are residential customers. This is not to say to Caller ID does not appeal to businesses. There are many great applications of this technology in the business community including computer security, caller-specific voice messaging, pizza delivery, and customer service. But telephone companies seem to be focusing on the residential market since it will give them the critical mass to make the service economical to them. Finally, Jerry expresses an interest in ... > A better Caller-ID system, though perhaps technically impractical - >would be a button or setting on your phone that explicitly asked for >Caller-ID. I would receive a notification of the request and could choose >to allow my identification to be sent, or not. This would be the >electronic analogue of your asking for my name - except that I would be >unable to lie about it... A system such as this is not far-fetched and may provide the ultimate answer to the Caller ID debate by balancing the caller's "right" to anonymity and the called person's right of privacy. I understand that AT&T and NTI are developing a similar feature at the switch level. Individuals who do not wish to receive anonymous telephone calls would be able to request that when such calls are attempted, that a recording be produced essentially stating that "the party you are calling does not accept anonymous calls. Please dial 1 to have your number transmitted or hang up..."

I don't think this survey is democratic, I think it's *demographic*. It is going to be presented as upper-middle-class and above results based upon the fact that it contains only respondents with access to a FAX machine. In addition, I doubt that it qualifies as any sort of scientific survey, as it will be biased towards those with enough energy to make a statement, which in this case is those upset by her performance. It's unlikely there will be a groundswell of people *actively* supporting her. Much as I disliked her performance, and think it was in terrible taste, I think the issue is trivial, and of no major importance. Jim Budler jimb@silvlis.com +1.408.991.6061 Silvar-Lisco, Inc. 703 E.

Our FAX machine (Brother 200) only generates CNG tones when it is in autodial mode. The trouble is, in autodial mode, if it gets a busy signal or a ring-no-answer, it just reports ERROR and drops the call. Therefore, I generally use it in manual-dial mode, where I can hear the call-progress tones from its speaker. I wait until I hear answer-tone from the far-end FAX machine, and then I press the START button. At that point, the speaker is cut off, and the machine sends CNG tones, followed by the actual data carrier. If I got a silent answer, I guess I'd have to assume its a diverter, and press the START button and hope... Doesn't sound very practical, does it?

I recently experienced the joys of "Follow-Me-Ripoff"... err ... "Roaming" while I was in San Diego, California about 2 weeks ago. One of the problems I came across was that San Diego (Pac-Tel Celluar) seemed not to have been able to handshake with my cell phone too well. Calls through the local dial-in worked fine, but calls forwarded from GTE Mobilnet/San Francisco seemed to die at San Diego. I would hear my phone being polled, but it gave up and then I got Pac-Tel's unavailable recording. I tried this about 3 times. I then tried *18 to (re)activate it, and it did work this time, but I sometimes wonder if it really worked after that. Another thing was that my phone was being polled about every 1/2 hour while I was in San Diego. I thought this very strange, as why would Pac-Tel Celluar care if I was still around or not, and what if I was in and area where it wasn't working (like inside the Performing Arts Center, where I was attending a convention). This is annoying because (a) I would assume it's putting a drain on my batteries and (b) it has a Rat Shack 3db antenna on it, and it screwed up our VCR's while I was making some copies, even though it was ten feet away!

Bunk, quite the opposite. Note "potential abuses by BUSINESSES" above. The key word is "potential". Aren't we on a witch hunt here and crying wolf to boot? Businesses already have access to a wealth of information about almost all of us, including our phone number if they want that. Every time you pay by check or credit card you have given up your privacy. And just how, pry tell, do you intend to do business with a company by phone without identifying yourself in some manner which reveals a lot more than your phone number? It's going to be pretty tough. It seems to me that what you really want is not to retain your right to pivacy but to create a NEW right to be anonymous. I think there is a BIG difference and the latter just simply doesn't exist in most legal definitions. >All you can get from this argument is that NON-BUSINESS lines have a >right to receive Caller-ID. For all their talk about protecting >people's privacy, the telco's REALLY want to sell Caller-ID to, you >got it, businesses. That's where the money is. There you go assuming things again. I find this hard to believe since the residence lines in most wire centers outnumber the business lines at least two to one. In some cases it is much higher. In order to completely debunk this argument, I need figures on national totals of residence vs. business lines and I don't have that so I am not on firm ground either on this point. Maybe someone else can provide more solid facts. I contend that the residence market for this feature is MUCH larger than the business market. >I'll argue that the knock on the door and the ring of the telephone >are equal invasions of privacy.

The phone ringing is analgous to a knock on the door. Answering the phone is like OPENING the door.

As an individual, just exactly how do you think you can see to it that this is enforced if there is no fool proof way to identify the caller? Just another well meaning statute that is effectively useless because the worst offenders just won't identify themselves. As you probably already can tell, I support the Caller ID feature (and this is a personal opinion and has nothing to do with my employer). As a matter of fact, as an individual, I really don't care if blocking is offered or not. When fully implemented, I simply will NOT answer any calls where the calling number is not present. Very simple and very effective. I simply will not deal with anyone who wishes to remain anonymous.

You can have such a system *today*, and have no need to affect the privacy of anyone else in having it.

I confess to not having seen any ads for it in a couple of years]: it will pick up the phone and nominally route *every* caller to an answering machine ... but ... you can program 'security codes' into it, and you can simply tell your friends whatever security code(s) you choose. The box will recognize the code, and your actual phone will ring ONLY after a person enters an acceptable code. For example, you could have a single 'password', and just tell everyone. OR ... you could have a group-password: give everyone at work one password, give the folks on your Ultimate Frisbee team a different number, etc. OR.. you can simply 'special' people to use *their*phone*number* as their 'password': that has the interesting side effect of your knowing that it is your brother calling no matter WHERE he is calling from. There are two interesting properties of this kind of approach, versus the 'big brother should do it all' approach: (a) no ones privacy is coercively invaded, and (b) only the people who want this kind of incoming-call-filtration need pay for it, and only their correspondents will have to deal with it. /Bernie\ ------------------------------ From: Mike Godwin Subject: Re: A Thesis on Caller ID Date: 13 Aug 90 11:34:13 GMT Reply-To: Mike Godwin Organization: The University of Texas at Austin, Austin, Texas In article <10786@accuvax.nwu.edu> 0004169820@mcimail.com (Gilbert Amine) writes: >This is simply not the case.

This analogy is not quite complete. The last time I used the "knock on the door" analogy against Caller ID, a co-worker pointed out that it is actually an argument for Caller ID. People forget that doors have windows and peepholes. If someone knocks on my door, I can see the person knocking and given that information, I decide whether or not to even answer the door. If I recognize the person, I have their identification without asking them for it. The same is true for Caller ID. Upon seeing the calling number, I can decide whether or not to answer the call. The ring equals the knock, and the Caller ID equals the window/peephole. I dont really understand why so many people have this "telemarketing list" fear of Caller ID. The way I see it, when Caller ID is fully implemented and ALL numbers are transmitted we will then have a powerful tool to filter out the meaningful calls from the chaff. This same co-worker has an idea that I like. He says that in addition to the number, CID should carry a code describing whether the call originates from a residence or business, then someone can market a high-tech phone that can be programmed to send all calls marked "business" to /dev/answering-machine.

MCI's North East customer service center is in Ryebrook, NY. The MCI rep was just dialling from her ACD console, and confrencing you in. The "outside" lines on the ACD's are just good ol' POTS lines with MCI as it's default carrier. I did this all the time also from San Francisco's customer service center (called the Pacific Division). Before MCI got it's first TOPS operator center in Omaha, Nebraska, we "completed" calls by geting one of these POTS lines on the ACD, calling 950-1022, dialling the number(s) ourselves, bridging the customer on, then releasing the call. The connection was poor, but the customer usually was concerned about getting through, and not too much concerned about line quality. If you call that MCI Ryebrook number back, you should get Customer Service, at least that's how it was set up on the old Infotron ACD's ... but now, they bought new Aspect ACD's, and the Aspect's may require dedicated outgoing trunks, as opposed to Infotron's ability to share incoming/outgoing lines. If you do get through, you may get a surprized rep, since the display on her console shows which trunk group the call is from ("Calling Card", "Trouble Reporting", "Customer Service", etc...)

In normal modem operation, the originating modem dials the phone and is silent until it sees a carrier presented by the answering modem. The answering modem detects a ring, goes off-hook, and sends a carrier to the originating modem. Then they go through their "connection" business to figure out if the other end is Bell 103 or 212A or whatever. An alternative mode of operation is available in my Micom-brand US$99 Hayes-clone modems. As part of the dialing command, there is a specifier to make the _originating_ modem produce a carrier after it dials, as if it were answering a call. The modem that is being called must pick up the phone as if it were making a call, and it will hear the carrier given by the calling modem. Reverse connections are no big deal in a manually-dialed call, because manual modems just have an originate/answer switch, and you flip it on both ends. In an automated Hayes-command environment, you have to change the way your software interacts with your modem. On my Micoms, the calling modem requires pause commas after the phone number in the "ATD" dialing command to wait for the call to go through. A letter "R" as the last part of the dialing string tells the modem to produce carrier instead of looking for it. On the answering end, I have not figured out any way to do auto-answering in originate mode with these modems. So, the software waits for the "RING" message from the modem, and then does a dial (ATD) command with no phone number. The answering modem thinks it is dialing a call, picks up the ringing phone line, and then detects the carrier produced by the calling modem. They do their "connect" thing and everybody is happy. There may be other modems that will auto-answer in originate mode, and mine may even do it (I just haven't bothered to pursue it). So ... Why would anybody want to do this? The first situation is the fax/modem switch-box, where the switch-box looks for modem carrier produced by the calling modem and transfers it to the answering modem. I use it for a modem on my company's PBX with Octel Aspen "automated attendant" call direction. There are no DID lines to people's desks at work. To reach an extension without going through a human operator, you call a main number that is answered by Aspen. You give it a touch-tone extension number, and it transfers you to that extension. The problem is that when the person picks up their phone, they get a message from Aspen saying "Transfer... Transfer..." and it takes fifteen seconds or so for you to get put through. It's no big deal on the voice side, but when you are a modem calling, and the answering modem picks up the line, it presents its carrier to the "Transfer..." message and by the time you get through, it's too late. With the reverse-originate setup, I can put in a delay which waits long enough for the real end-to-end connection before doing carrier. (You may ask why I didn't go for a direct-line to the outside. This way, the modem can be called from any internal extension and take advantage of tie-lines between sites. Besides, it's one less trunk to pay for... :-) The whole thing sounds like a pain, I know, but it takes longer to explain it than to set it up (as long as you can customize your software on each end).

I know that ATT has put "This is copyrighted, but we don't intend to ever publish it" notices on Unix source code (and a lot of other chunks of binary unix copies too.) However, with thousands of copies of it sold, and at least that many in the hands of CS majors, a jury might well rule that ATT had effectively published the code. If so, then what Len had on his machine is very likely to fall under the "fair use" provisions of the copyright law. As is clear from the affidavit supporting the warrant under which Len's computers and reference materials were taken, ATT is the motivating force in the Len Rose case, just as Bell South was in the Neidorf case. It seems possible that this case might blow up in their faces even worse than the Neidorf case did, making Unix source code freely available as reference material (which might not be that bad for ATT). Another thing, I have been a faithful ATT LD customer since the breakup, but their role in this case is making me reconsider.

Levine" Here in the Garden State, 411 gets you directory assistance for your NPA. The 609 NPA is divided up into two little bitty LATAs, but 411 will give you numbers in either LATA for free. (Well, free for the first 10 calls per month, but that's pretty close.) The local phone book, which lists both 908 and 609 numbers doesn't say whether 411 from a 908 phone will provide 201 numbers. I'm sure it does now, but I wonder whether they plan to split the current 201 DA bureau into two parts, and if so, whether they want to charge for calls from 201-555-1212 from 908 and vice versa. Calls from 609 to 201-555-1212 are inter-LATA calls and cost whatever your carrier charges. My carrier, Sprint, charges 50 cents with no free monthly allowance, even though they still give you a free interstate DA call per month. Meanwhile in Massachusetts, 411 gives you local DA, and 1-555-1212 gives you long distance DA within your NPA. At least before the 617/508 split, I would occasionally dial 411, and when I named the city the operator would tell me to call 555-1212 instead. Since the split, nearly every point in 617 is a local call from nearly every other point and I don't know whether they still bother to make the distinction. The last time I checked, 617 and 508 had the same DA bureau, you could call 508-555-1212 and get a 617 number. From residence phones all intra-state DA calls in Massachusetts are free. My Sprint bill occasionally has a call to 413-555-1212 with a listed .00 charge. New England Tel uses the 555 prefix for a variety of special services, most notably 555-1616 is residence or coin phone repair.

That's a handy number to have. Since they disabled (or changed ??) the 958 and/or 311 numbers here, there's been no easy way to identify which line you're calling from. Anyway, here's a summary with some expected -- and unexpected results: 1. Home. Worked fine and gave the complete, correct number, even though the Pollen Alert prompted me to enter a number. I used one of the modem lines, so if some sleazoid telemarketer calls, he'll just get the tone. (Serves him right ;-) 2. Office. (System 85 w/DID) Gave the number for one of the trunks used for outgoing only, not the calling extension. Accounting and billing is done internally with a call detail recorder, so I can see how it's not important. 3. Cellular. Gave a number on one of the prefixes with the switch in the same building as the Ma Bell cellular switch. Nothing even close to the actual calling phone number. 4. Here's the interesting one. COCOT's. The first one I tried was at the University. It's a Genuine Bell COCOT, complete with logo. (I would have thought that Genuine Bell would have put in something better than that funky phony dial tone. Sounds like a 555 chip. Also I would have thought Genuine Bell would have silenced the real dial tone and the outpulsing of the stored DTMF.) Surprisingly, the ANI registered the EXACT number posted on the phone. When I tried it from another phone ... 'The nummmberrr you have reaaaached ... is not in {scratch!} serrrrrvice {click} for incoming ...'. At a local shopping mall, there's a whole row of counterfeit Bell COCOTs (sans logo, of course) all with the same number. ANI gave NOT the posted number, but a similar number on the same prefix. Out of curiosity, I called it. It rang, but the COCOT did not ring. When I picked it up, it was obvious that it was the correct number, but talking path (both ways) was blocked. When I punched the keypad of the called COCOT, it did transmit to the calling phone. The bottom line is -- were I a telemarketer and I were compiling a list of numbers to harass, er.. I mean contact, would I find this service of use ?? Out of four examples, only two gave an accurate report of the calling number. Out of those two, one of them is a COCOT which cannot receive incoming calls. That drops it down to 25%, if you consider the modem line to be a valid 'hit'. If you consider only the cases where a telemarketer could call the number and get someone with a pulse, it scores a big zero. In any case, it's a good demonstration of what the system can and cannot do. I think that's what they had in mind. Good Day!

It's just some cheesy thing the merchant has installed... It is styled much like an old-fashioned 2500 set, but is beige and push- button (I didn't place a call, so don't know if it's DTMF or what). However, it is taller, as it has a coin box built into the bottom. It has a slot in the top designed to take quarters, and a sign "LOCAL CALLS ONLY - 25 cents for 3 minutes." The instructions were "Deposit 25 cents, dial the number. When the party answers, press the 'push to talk' button. At the end of 3 minutes, you will hear a beep - deposit another 25 cents for three more minutes." I'll bet it's hooked up to a POTS line. Since it was at the cashier's desk at a restaurant, I wouldn't be surprised if it's on the "main" number for the business. There was a "coin return" chute, apparently for calls where you hung up before pressing the "push to talk" button. The label on the back said that the beast was called a "Europhone Coin Telephone". The manufacturer is American Communication Technology, at (213) 217-1818. The set was padlocked to the counter. It was at the "Park Pacifica Cafe" - 650 Cape Breton Drive, Pacifica, CA. (*really* obscure place - at a horse stable accessible through a residential area. Great food, great prices, though!) I was with some friends, so I didn't have time to play with it. It would be interesting to see just how it works, how it enforces the "local calls only" restriction, as I believe Pacifica still doesn't require a "1" for long distance intra-LATA calls. From the looks of it, I doubt very much that it could have any intellegence inside of it. [Moderator's Note: The tone pad is special, and is programmed to restrict more than seven digits, or numbers beginning with 1. It partly depends on the honor system, which is why this model usually sits near the watchful eye of the cashier or owner of the establishment. We have one here next to the cashier in a liquor store on Howard Street.

Basically, flashing the line is ignored before the call supervises, and produces the secondary dialtone after supervision. Well, I was fooling around tonight, and discovered that the Sprint FON-card system doesn't return supervision until the eventual destination answeres. So, during the time when I'm entering the destination number and my FON-card number, the call hasn't yet supervised. I find this quite interesting, and it has a number of side effects. Those of you having cellular phones and a carrier who pays attention to actual supervision in determining when to charge for calls, take note. This means that you can use your FON-card from your cellular, and not pay any airtime for non-answered or busy calls. ------------------------------ Date: Mon, 13 Aug 90 10:08 EDT From: "Scott D. Green" Subject: DA Puts the Call Through High on the list of "Why can't (fill in your favorite TelCo) do (fill in your favorite dream feature)?" is "Why don't they connect you to the number you've just requested from DA?" Well, in Philadelphia (215) they can. Once the DA operator turns you over to The System, you are first asked to press 1 if you wish to be connected directly. For $.30. In addition to the regular DA charge. Only after It explains that option will It recite the number you've requested. You may still press 1 at that point to call. It appears to work only from within the city so far. The other change is that you must dial 1-555-1212 to reach DA now. Formerly, (and in the exchanges where this is not implemented) one could dial 1-555-xxxx. The advantage there is that if you didn't use -1212 you wouldn't be billed with the DA call. Just wondering - wouldn't this be a neat way of reaching people with unlisted numbers? They now have two categories of "unlisted:" not published in the directory but available from DA; and totally unlisted. How about a third category: not published, not available from DA, but connectable through DA? scott ------------------------------ Date: Mon, 13 Aug 90 10:18 EDT From: "Scott D. Green" Subject: Norristown PA Announces a New Weapon Against the Drug Trade Yesterday's {Philadelphia Inquirer} reported that Bell of PA, at the request of Norristown (a western suburb of Phila.), will be removing touch-tone public phones from drug areas and replacing them with rotaries! They got the idea from that other backwater town (I forget where) that we discussed a while back. Norristown believes that if they can't call the beepers, they can't score, the dealers will go out of business, and the drug problem will be solved. (Quick, somebody call George Bush). Some official (their tech consultant, no doubt) did mention that the tone generators were readily available elsewhere, but (get this) the possession of such an instrument could be construed as probable cause! Bell said that they are happy to help, but they will be watching the maintenance/vandalism rate, since rotaries are more easily vandalized. (Especially by druggies who can't score because the Radio Shack is closed). Bell said that if costs increased too much, they would have to go back to touch-tones. scott [Moderator's Note: The fools!! Haven't they visited Radio Shack lately and seen how the 'probable cause' abounds? Haven't they heard of voice pagers with direct dialed seven digit numbers upon which coded announcements can be recited, or tone only beepers with dual addresses, each of which has its own seven digit (easily rotary) dialed number making two pre-planned instructions possible? And cellular phones can't be dialed from rotary? All they are doing is making use of the phone more difficult for *everyone*. It stinks.

The first way is that they set up two separate accounts and put a 'pointer' on the second line that says to print billing info with the first. This cause AT&T reachout billing to show up on only one line. The second is when you have one account with two numbers. This is how your account should be set up for calling plans to show up on both lines. It took Southern Bell and AT&T four months to figure this out. I assume this affect the ANI information ... not sure. Bill [Moderator's Note: I get the 'benefits' of Reach Out America on both lines for a single fee.

Cable & Wireless claims to have a 100% digital network. Most of my experience has been in intra-state calls, so cross-country calls may or may not be a different story. Call completion time is slower than AT&T direct dial, but is reasonable. Detailed billing (with caller's ANI) is not available. You get a daily summary, as well as subtotals for hour of the day and day of the week. Customer service cannot be reached from Canada. There is no POTS number to call. Also, programmable 800 cannot terminate in Canada, although a US user can receive calls from there if you pay for the option. They claim to be working on Canadian customer service for availablility by year's end, but don't know more than that. They have about six prefixes from which to choose. ------------------------------ From: A J Annala Subject: The LAW vs. Telephone Access Devices Date: 14 Aug 90 03:32:41 GMT Organization: University of Southern California, Los Angeles, CA I do some data communications technician type contracting work from time to time (e.g. installing modems, analog line testing, protocol analysis, etc). There have been notes on the network about police confiscating equipment of the type I often use in my work. These devices include ATT Craft Test Set, Progressive Electronics 200B Inductive Amplifier, Dracon D814 Impact Tool, and a Progressive 77M Tone Generator. The police claim is that such devices are telephone access devices which should not be in the hands of the public. I am curious about whether any other technical people have been challenged by the police and what answer has satisfied them to go away without hassle. All of these devices can be purchased over the counter or by mail at very reasonable prices from Graybar Electric Company, 210 S. Anderson Street, Los Angeles, CA 90033 (213)265-7000. In this context it appears to be to be completely ludicrous to claim these tools must not be found in the possession of members of the public. They are ordinary tools.

I would like to assemble a list of similar numbers to call to get a positive identification on a switched voice grade line when I punch down cross connect wires from the telco demark to modems in my computer room and customer sites around town. As a matter of curiosity, I would be interested in learning about how sucxh numbers are allocated throughout the country, what the typical numbers are in local regions, and whether there are any other commonly supported numbers (e.g. ringback) for installation assistance?

PT] Jeez, am I the only one who doesn't think GTE is, if not the Beast in person, at least a direct representative of all that is evil? :-) We're right smack dab in the middle of GTE-land, and I don't really see them as being all THAT much worse than anything else I've used. For my purposes (POTS, dial-in to the college, calls to Telenet in Des Moines [at the 55-mile distance rate! Ack!]), they seem to do the job. Then again, they've been taking it in the shorts over their proposed rate hike here. (Did I say "hike"? "Forced march" is more like it.) But being taken to the cleaners by the phone company is hardly a novel idea, and that's what we have PUCs for. But the phones do work. Heck, even the critter the college has installed (Omni S/III or something similar) seems to work all right, at least as far as I can tell from my desk. Maybe having GTE operations in town makes a difference. Grinnell until recently was the HQ for their Midwest operations, but I've lost track of what the heck they are these days. My monthly check now goes to GTE *North* (used to be GTE Midwest right here in town) in Indianapolis (which is to the *East* :->). That might matter -- if I can't get the attention of their repair service, I can always ram one of their vans... :-) :-) I hate disclaimers, but since this affects town-gown relations . . . The above is my personal opinion. It has nothing to do with Grinnell College, GCCS, the Board of Trustees, or the price of tea in China.

It works by calling 1 800 23 GLOBE and using a credit card and the number of the fax where you are at. Before long, the G&M sends down its stuff to the fax machine you specified. This is handy for travellers, say, who want to pick up the latest news and stuff. One interesting thing is that the {Globe and Mail}, being a Canadian paper, is using an MCI 800 number (according to the 800/OCN table in the TD archives, for 234 prefix) which would be accessible througout North America. However, the {Globe and Mail} ad says that this number should be accessible throughout the world (though outside North America at a toll charge). Can 800 numbers be accessed from outside North America via overseas dialing (other than a rigged-up in Japan)? [Moderator's Note: The {Chicago Tribune} also offers a similar service by pre-subscription. Every day at 4:30 PM they fax you the main stories in the paper for the next day. I liked it better (and it was a lot cheaper) when we were able to get the next day's actual paper anytime after 4 PM weekdays. We can still get the Sunday {Tribune} anytime after about 10 AM Saturday morning. The weekday Fax edition is very expensive. $$$$$ PAT] ------------------------------ From: yilmazer@suns01.UUCP (Sedat Yilmazer) Subject: Re: Caller-ID Again Date: 14 Aug 90 05:58:30 GMT Reply-To: yilmazer@suns01.Nowhere (Sedat Yilmazer) Organization: Alcatel Austria, Vienna In article <10793@accuvax.nwu.edu> dave%westmark@uunet.uu.net (Dave Levenson) writes: >With the introduction of Caller*ID service, however, crank calls have >all but disappeared in this area.

Well, it *should* depend on where you are/what you're doing with them. If you're up on a pole in a parking lot in the middle of the night, they should be more suspicious than if you're working in an office in the middle of the night. It is always helpful to have the name and number of the person who authorized your doing the work handy. I was installing for a customer who had the misfortune to move his office during the great NJ phone strike. Since he couldn't get any service orders through, and I informed him of the probable backlog once the strike was over, we decided to run our own poles and cable since it was all on his property. I had a few inquisitive looks from the local police when I was up on the poles, since there was a *lot* of vandalism in the area (things like a pedastal terminal being pulled out of the ground by a pickup truck). In fact, one of the customer's building feeds (500 pr) was cut, and a *very* over-worked manager showed up to splice it. I wound up splicing it while the manager got a well-deserved rest, since I was about 4x faster. So, it depends on the situation. Even a simple screwdriver could be considered burglar's tools in the right situation - but if you indeed have business in the area, it shouldn't be a problem.

Taken ad absurdam, having a computer with a modem attached could be contrued as a telephone access device. After all, look how much crime is perpetrated these days with such equipment. The other question concerns the definition of "public". Does one have to be an employee on definite assignment by a bona fide telephone utility to legally carry and use telephone test equipment? I, and a number of my friends, do a heavy amount of telecom consulting. We routinely use line analyzers, punchdown tools, and butt sets. None of us "work" for anyone but ourselves.

Some years ago, I needed to perform some audio measurements on a small FM station in Los Gatos. The Los Gatos cops are jokingly referred to by the locals as the "Los Gatos Metropolitan" police. I have personally seen repeated instances where the LG Fuzz act as if they are NY wanabees, having about as much small town finesse as a bulldozer and a wrecking ball. Anyway, shortly after midnight I was carrying equipment (distortion test set, monitor receiver, etc.) from my truck into the studio. Suddenly, an officer pulled up and demanded to know what I was doing and wanted to see "ID". I produced my license and explained that I was making tests on the radio station. This wasn't good enough. While he was eyeing over the equipment, he asked things like, "How often do you do this?" "Who 'authorized' this?" "How much is this equipment worth?" "Where are your receipts for it?" Finally, with the evening moving on apace and a lot of other things to do that evening, I told the officer that I had identified myself and explained my purpose in being at that location. All of his other questions were irrelavent and none of his business, that I had work to do, and invited him to either arrest me or leave the premesis. He considered that for a moment and decided that he would leave, but not without giving me some friendly warnings about doing "suspicious" stuff in his jurisdiction. The next day I called the Los Gatos Town Hall and informally complained about the incident. I got the expected "we're only doing our job" and then was told that the officers would be advised that midnight to six work would sometimes take place at the radio station. From the way things are going these days, my challenge to the officer would now result in my arrest. John Higdon | P. O.

The first pair are the Red and Green and the second pair are the Yellow and Black. For a one line installation, you only need to connect the first pair (Red and Green). The second pair is often not connected through anymore - standards have gone to hell since divesture. The telco used to connect the second pair (Yellow and Black) when installing so that if they popped in a second line they wouldn't have to hunt round the premises to splice all the second pairs. > The modular jack that goes into the phone has four wires in it. Why > is that, if only the red and green are required for service? Just in > case you have a two line phone? There are several reasons for this besides a second line. At the end of this posting I am including something I posted in November 1988 in response to an inquiry just like yours. > Why is the jack that goes from the telephone headset to the > telephone a different size than the jack that goes from the phone to > the wall jack? Is it to idiotproof the process? Also why four wires > into the headset? Does the phone itself do anything to the signals > before it sends it to the headset? If the proper size jack was put on > the headset could you plug that into the wall jack and receive calls? Because it serves a completely different purpose. It idiot proofs it to some extent. But I have had customers plug the handset into the line jack and then call and complain that the line cord wont plug into the handset jack - this really has happened. Notice that a handset jack has and uses two pairs (four wires). It uses two wires to talk (Transmitter) and two wires to listen (Receiver). Ok, so the line jack is two wires (talk and listen on the same pair) and the handset has split talk and listen into separate pairs. Inside the phone instrument there is a device called a network that magically sends the voice signals to the right place. Yes, you could Micky Mouse a handset to work directly on the line, but the line voltage would soon kill the receiver magnet and the sound of your own voice would blow the wax out of your ears etc. So that is what the instrument stuff is for, if it wasn't needed, someone would have been selling handset to line cord adapters years ago. The Linesmans "Butt-set" has the network built into the handset as does the AT&T Trimline phone. > What do the two wires (red and green or yellow and black) carry? Is > one positive and negative like electrical wires? Yes, as a phone line is about 48V DC when "on hook" (hung up) and between 3 and 9V DC when "off hook", there is a DC voltage there. The normal voltage polarity is Green = + and Red = -. Some phone systems will reverse the polarity when a call goes through (rare these days). If the polarity is wrong, no biggy, some old 2500 sets may no longer dial, so flip the Red and Green and everything will work again. They phone wires also carry audio signals, Voice and Touch Tone. They also carry the ringing signal 40-150V AC. > In the case of my second line I bought a double wall phone outlet.

Yes, you could have a break in just one wire in a cable. This is not uncommon. I have had this happen with long runs of cable, this is a good reason to install more pairs than you need. If you have a "bad pair", just mark it as such and progress. But as you are a domestic installation I would physically check the wire from the NIU (Protector) to the jack. There may be a connecting block or jack along the way that has not spliced the Black and Yellow pairs. One word of warning. Some lazy installers will often place the Black and Yellow under a screw in a a junction box/jack but will not strip the wires. It will look like two wires are connected under a screw head, but as they still have insulation, they are not. And now if you are still fascinated by all this stuff, here's more of the same. This is a posting from a couple of years ago that kinda covers the same ground. Newsgroups: comp.dcom.telecom Subject: The other pair of wires. Message-ID: Date: 9 Nov 88 10:11:08 GMT Sender: chip@vector.UUCP Lines: 54 There has been a fair amount of discussion about what you will find on the second pair of phone wires in a residence. Here is a list of what you might/could find: The first pair will always carry a regular phone line. These wires are usually Red and Green, they can be White with a Blue Stripe and Blue with a White stripe. They are referred to as Tip and Ring. The Green or White/Blue wire is Tip and the Red or Blue/White is Ring. Tip is Positive and Ring is negative. ( Yes I know the voltage thingy is more complex than that, this is not for experts. For folks with Rat Shack meters, what I have said is true) Ok, now the first pair is out of the way, let's look at the second pair. They are usually Black and Yellow or White/Orange and Orange/White. These wires can have several things happening to them, but not all at once. First of all, there can be nothing on the wires, and they may not be connected anywhere. Next, the Yellow wire can be grounded. This is rare these days, but you will find it on old installations. Another old thing you will find is AC voltage for lighting the dials of old Princess phones. If you look around, you will find a wall transformer wired into the Yellow and Black wires. If the transformer says, "Bell System Property" etc. That's it. If you no longer have a rotary dial Princess with a lighted dial, pull it. Talking of old, old style multiline "business" phones. Yes, the ones with the buttons that light up and flash, they needed a hard wire signal to know that a line was off hook. This was known in "Telco speak" as "A-Lead control". If a single line phone was used as an extension on one of these systems also known in "Telco speak" as "1A2", the second pair (Yellow and Black) were shorted together when the phone went "off hook" to let the system know that a line was in use so all the right blinky lights came on. If you used a phone without A-Lead control, it went into hold when you hung up - most inconvenient. These days, if the telco uses the second pair, it is usually for a second line. Looking back to the first paragraph, the Black wire is Tip and the Yellow wire is Ring, usually known as Tip 2 and Ring 2. Yup, that makes the first pair (Red&Green) Tip 1 and Ring 1. Now, when discussing PBXs and modern "Key Systems", the second pair can often carry "data", stuff controlling the phones. More details available upon request.

I remember in 1977 calling the NJ Bell operator from a payphone in south Jersey (in order to find out how many quarters, dimes, and nickels I'd have to go schnorr from the cashier at the diner in which the instrument was located to pay for a three minute call down south), and I asked for the rate to . Lo and behold, as I listened in, the operator enunciated some command phrase, and the six digits I had given her. A digitized human voice responded with a string of digits which represented the rate (no punctuation, just digits). I asked the operator if the computer was controlled by her voice and she said "yes, it responds to my voice". Given that commercially available voice recognition was first trendy (and of miserable reliability) about 1980, that was truly neat stuff for the epoch. I'm looking for details: Who did it?

Unfortunately, the service rep's description errantly led me to believe that Pro Wats/Texas was billed at six second increments as is (interstate) Pro Wats. Unfortunately, it turned out to be 1 minute increments. The discount rate for Pro Wats/Texas was crummy, and without the benefit of a six second increment, the plan became nearly useless for me. Thus Pro Wats/Texas was cancelled. (BTW...if you do any polling with Telebits, do check out Pro Wats. The discount is nice, but the six second increment is where I save the most money.) A month or so back, Pro Wats/Texas was overhauled to 30% discount, $5/month, and no setup fee. Even with the crummy one minute billing increment it now becomes worthwhile. So I called to sign up. But, just to avoid a repeat of the earlier fiasco, I asked for a printed description of the service. That way, I'd understand exactly what it was, and there would be no room for confusion as there was last time around. "I'm sorry, sir," the rep answered, "we don't have any literature available." I pressed for any information which described what the plan is. She appologized, but said all their stuff was for the old version of Pro Wats/Texas, and nothing was available yet on the new plan. So I inquired, "are you telling me that you can't put it in writing?" There was a very long pause on the other end. Eventually, the rep recovered, and in a very animated voice offered to draft a letter describing the service and include all the details I wanted. I think I found the right button.

Wouldn't it make more sense for AT&T to extend that "out of area" message to Canadian 800 numbers as well, so that US callers will realize that they must dial direct to Canada, rather than fall under the impression that the firm in Canada which they are trying to contact no longer exists?

At 12:30AM, it was still working fine. At 1:10AM, it was no longer working, ie, it defaulted back to my home system, and never made it Boston. I tried reactivating it, but that didn't work till 2AM, Eastern. When I talked to GTE about Follow Me a while back, they mentioned that the service is run through a central computer in Houston. (At least for GTE Mobile Net customers it is ... or so they say). Could the early termination of Follow Me Roaming have anything to do with the fact that at 1AM Eastern it is 12AM Central/Houston time? Perhaps that is why I am losing all my calls at 1AM, two hours before GTE in San Francisco SHOULD un-forward Follow Me. Any ideas on this? Incidentally, I can't recall who (Robert?) wrote that he experienced problems with Follow Me while in San Diego. I had a similar problem in Sacramento, and when I called GTE they told me that the reason the Follow Me is slow and/or that when I roam into another CA service area it doesn't work is becuase they are doing away with Follow Me in CA. Or, more aptly put, it will work automatically in all CA service areas, like Cell One already does. (In CA, if you have service with Cell One, you can be reached anywhere in CA or Reno, NV with one phone number. I'm not sure if this uses a DMX or it polls you as you enter a new area and lets your home system know where you are...) GTE apparently decided it was about time they did this to, so what happens is that when you roam into a service area in CA, your home switch is told where you are. However, since the system is new, and the trunk lines aren't avialble to call the ROAM system you are in, callers calling your mobile number will either get a re-order or dead silence, since no lines are available to call to the Roam system yet. GTE said that by the end of August this will be fixed, and that in the meantime to use Follow Me, even if you have to re-enter *18 a few times. I'm not sure if this answers your problem, but it sounded a bit similar to what I had experienced. Additionally, does entering *18 (repeatedly) force you to the back of the queue, thus slowing down the implementation of your request? IE, if I press *18, see nothing happens, and then try it again, does that cancel out the original *18 request, and make me wait for however long Follow Me takes to implement a new system? GTE told me not to enter *18 a lot of times, since it would just increase the time that it would take for Follow Me to activate at my home switch ... is this true? Doug dreuben@eagle.wesleyan.edu dreuben@wesleyan.bitnet [Moderator's Note: Through some agreement between (I think) all cellular carriers, there is a general cancellation of all 'follow me' requests activated during the day at midnight *using the time where the computer is located which is holding your request*. If California is holding your request, cancellation will occur at 3 AM Eastern. If New York is holding the request, then cancellation will be at 9 PM on the west coast. If GTE Mobilnet works from Houston, then Central time would prevail. PAT] ------------------------------ From: Henry Troup Subject: Numbering Plan Changes (was Re: Is 510 Area Code Active?)

There's going to be a new North American Numbering Plan. The existing plan has approximately 160 NPAs (area codes/Numbering Plan Areas) with about 640 office prefixes and 10000 lines per office. That totals to just about one billion (1,024,000,000) lines. The reason we're running out, perversely enough, is not the dense area codes, but the sparse ones. Montana, for example, with a whole NPA to itself. The new NPA will impose everywhere what is already a fact of life in dense area - no 1 + seven digit toll calls. Then the area codes can be used as office prefixes, and (the real change) all office prefixes - now 800 - can be used as area codes. So the total capacity goes to 800 x 800 x 10000 or 6.4 billion.

I wonder if Sedat's blissful crank call-less world is due to the fact that most of Europe -- and I therefore presume Austria -- charges for local calls, making crank calling a much less attractive 'hobby' of the eight-to-ten year olds and drunks that I seem to get? Anyone have any facts or opinions on the relative rates of crank calls. On another track, when I lived in the U.K. we were taught to answer the phone with the number. I presume this dates from a time when the switching system was even less reliable than it is today. But in North America one thing you never do is tell a caller what number s/he has reached.

Here is my translation of the article: Telefonica, the Spanish telephone company, was astonished. "Stoned by sniffing our telephones? Is that possible? Please don't spread it around! Otherwise no telephone booth will survive", a spokesman begged in vain. Spain's Conservative Party will make some questions about this telephone sniffing in the Parliament. The rumour started in Granada. A local newspaper stated that drug adicts were responsible for the sharp increase of vandalism of public telephone booths. A telephone technician said "They break the hearing part out of the telephone and burn the parts because the smoke has a narcotic influance with which they get stoned." His bosses immediately denied it and did counter research. This revealed that no "strange parts" were used in the telephone making. Still the rumour was all around Spain. The PTT acknowledges the increase of repairs of telephone booths. The police thinks that the rumour has started due to the fact that in Granada an old fashioned glue was used to glue the telephone horns together. So it is a variant on the old glue sniffing. No one has been able to prove that Spanish youngsters did get stoned due to the Spanish PTT, like the Spanish opposition keeps on claiming. The Spanish people will desperatly have to search for an undamaged telephone booth as long as the rage of the telephone sniffers lasts.

In Pac*Bell land no one seems overly eager to do this. It took five minutes to convince a Pac*Bell rep that a friend's voice BBS was strictly a non-business enterprize. In fact, I once had the goods on a telemarketer who was using residence lines and got nowhere. In non-rural California, measured service is mandatory for business lines while residences can opt for flat-rate local calling. Some of the telemarketing slimeballs will go to some lengths to stash a couple of harassment machines in someone's house connected to residence circuits. One of these machines called me one evening without the mandatory live person introducing it. For the express purpose of nailing these guys, I answered the machine's questions and indicated that I wanted to have a callback. Then I listened to the machine drop off. To my ear, it was unmistakenly a call from another line in my crossbar's marker group. For those unfamiliar with this sound, it is essentially no sound -- the call just goes away. It can only do this with a call originating from the same switch. When the live person called I made up some excuse to have to call her back. She was very hesitant to give me a call-back number, but when I indicated that it seemed strange doing business with someone who refused to give out a number she gave it to me. It was 265-something. Sure enough, my switch. I reported this to the Pac*Bell business office, telling them that this particular machine had given me the spiel without a live person introducing it. I was later told that I must have some wrong information because the number I provided was residence service so it couldn't possibly be used in telemarketing -- "that would be against tariff!" "Besides," she told me, "the woman who answered the [residence] phone assured me that all the solicitation calls [pertaining to the business she apparently wasn't doing??!!] were made from Wisconsin." Yeah, and I'm Ronald Reagan. John Higdon | P. O.

Thanks for the interesting articles on TELEX/TWX in the past few weeks. Can anyone explain what a "cable address" is? For example, the cable address for the Gibraltar Broadcasting Corp. is "Broadcasts." If I wanted to send a cable to them, how would I do it, how would it get there, what would they receive it on, what role does the address play, who keeps track of the address, etc. Davie Brightbill [Moderator's Note: Cable addresses are nothing more than shorthand for the entire telex address. They were devised many years ago by Western Union as a sort of precurser to what we call 'speed dial' today, or 'abbreviated dialing'. Except, you really did not dial anything. You merely passed the cable address to the Western Union agent/operator, who had a lookup table of addresses versus telex numbers. They were used as advertising gimmicks, and ways to easily remember long numbers. Although 'cablegrams' were sent out of the United States and 'telegrams' were sent domestically, they were the same difference, and anyone could have a 'cable address' if they paid Western Union to list it in their tables of same. 'Cable addresses' tended toward to be easy to remember words and phrases. A few I remember still were 'University' (for the U of Chicago); 'Beacon Hill' (I forget who owned it); 'TribTower' (Chicago Tribune); and 'Symphony' (The Chicago Symphony Orchestra). This was all 1950/60-ish stuff. I did not know they were still making them available. I guess any telex carrier can do it. In your example, you would call Western Union and tell the operator to send a message to the cable address "Broadcasts". That is, *IF* s/he even knows what you are talking about! :) PAT] ------------------------------ From: "Craig R.

DAVID systems has a PBX cum Ethernet which has been sold to Ameritech as a CO LAN. There are Ethernet jacks on the back of the phone sets, and any Ethernet capable equipment can be plugged in. Once the data gets to the PBX switch, it is turned into real Ethernet. "Real" Ethernet devices on coax can also be used with the system. Switches can be connected via coax, Ethernet, or (multiple) T-1 spans. Ethernet packets can be gatewayed between switches on any of these links.

Likewise, the 'time of day' message is from an earlier era. Beginning in 1927, telephone companies began getting tired of people ringing up the operator to ask 'what time is it?', so they established special numbers for that purpose. In the beginning, a live person sat there and announced the time upon request, and there were very few ten second intervals that *someone* did not dial in asking for it. The original number for the time of day in New York City was NERVOUS. A jewelry store in Manhattan sponsored it for many years. Recorded messages giving out the weather forecast started in 1950 in Philadelphia and Cleveland on an experimental basis. It seems a lot of people had been calling the operator to ask what the temperature was that day, and the telcos got tired of that also! :) But for other purposes, recorded announcements began in August, 1955 in Scarsdale, NY when Hitchcock Memorial Church began broadcasting recorded prayers continuously over a special telephone line installed for that purpose. By a year later, churches all over the United States were experimenting with this new technology, offering 'Dial-A-Prayer' telephone lines. New York's Fifth Avenue Presbyterian Church averages 800 calls per hour around the clock on their present system. About 1958, theatres began using recorded announcements advertising the pictures and the times they played, however the recorded telephone message concept was mainly used by churches until the middle sixties. In 1968, Chicagoan Sherman Skolnik started a recorded message commentary on the news which ran five minutes in length, was changed daily, and has continued to this day, 22 years later. In the early 1970's, several non-religious recordings were available, including a convention and tourist message in Chicago; a 'gay news and events' recorded message here, and others. Of course today, there are literally thousands of free recorded annoucements to hear, to say nothing of the many operating on premium charge lines (900/976 numbers). Except for telco weather and time messages, public programming / general interest recorded announcements began 35 years ago this week. And, it was just ten years ago that 900 service was started by AT&T, to handle the calls received in the Carter/Reagan debate in 1980. Should we celebrate the anniversary? More than a few people have gotten rich from telephone recorded announcements, that's for sure! Patrick Townson ------------------------------ Date: Wed, 15 Aug 90 22:51:44 CDT From: TELECOM Moderator Subject: Long Distance Piracy Jolts Phone Bills An article of interest in the {Chicago Sun Times}, Monday, August 13 discussed phone phreaks who gain access to companies' outgoing phone lines via incoming 800 numbers tied into the PBX. Writer Lisa Holton discussed 'sophisticated thieves who take advantage of lax firms, casuing (the firm) to pay the piper.' In one notorious example from the not-to-distant past in Chicago, a company had been getting monthly bills for their long distance service of $2500 to $4000 per month. Then one month, the bill came and the total was $105,000. It was not a misprint. It seems in this case, on a Saturday between 8 AM and 8 PM, when no one was working, there had been several *thousand* internatinal calls placed through the company PBX. Someone had gotten a list of the valid PIN codes, then sold them to dozens of buyers, usually in immigrant neighborhoods, for $20-$30 each. Sometimes more than one person bought the same code number. According to Loren Proctor, Chicago area regional security manager for US Sprint, incidents like this are quite common, although not necessarily as outrageous. He said Sprint can often times detect a fraudulent pattern going on, but the company disclaims responsibility for fraud calls made through a company's own switch. Ms. Holton discussed three common techniques used by phreaks to obtain access codes: 1) Playing the numbers game: This is simply the brute force technique. Have your computer just keep trying number combinations until one or more work. Because many PINS are only four digits, it is just a matter of time -- a short time, really -- until valid codes are found. 2) Buttering up the company operator: The phreak calls up a company, and asks to be transferred to the sales department, or somewhere. He gets the department receptionist and says he made a mistake, could he please be transferred back to the operator. Now his call is on an inside line, so who else could the operator be talking to besides an employee? If the operator is busy, or not paying attention to who she is talking to, the phreak can talk her into giving him an outside line. Bingo, a three hour call to his mother somewhere. 3) Looking for codes in all the right places: In this example, thieves were hanging out at Port Authority Bus Terminal and at LaGuardia International Airport. They were using binoculars and telephoto lenses on cameras to watch people making 800 calls into their company PBX. These guys were writing down the 800 numbers and PIN codes, then giving them to partners up on 171st Street who would sell them for $20 each. They also watched for people to enter 950 numbers followed by codes and Sprint's 800 number, followed by codes. This went on for about 24 hours before Sprint caught on to what was happening. So, according to Ms. Holton's article, the experts give these tips to help prevent piracy of your long distance lines: 1) Change PINS as often as possible. If PINS change quite frequently, it will be more difficult to find one that's valid. 2) Give the PIN as many digits as possible. According to Mr. Proctor of Sprint, fourteen digit codes are now common with long distance carriers. The longer the PIN, the more difficult it is to learn by the brute force method. 3) Limit access to the PBX: Take an analysis of everyone who is using the phone system and WATS lines. Does the shipping clerk need the same access as the Chairman of the Board? Toll-restrict 900 numbers, as well as off-site 800 number access by time of day or day of week. Limit the number of calls a user can make in a single day. Some companies go so far as to pull the plug on the PBX after 6 PM, so that *no one* -- phreaks included -- can use the phone. 4) A device is available from Information Innovators in Virginia Beach, VA which is attached to the PBX via a PC. It will shut down an 800 line for a short period or indefinitly if it senses someone is making repeated efforts to break in or locate a valid PIN. None of this, of course, comes as anything new to TELECOM Digest readers, but I thought you would enjoy excerpts from the 'tutorial' given in the {Sun Times} for businesses plagued with phone abuse problems. Another reference is the August issue of {Teleconnect}, which has a lengthy story on this same topic.

The "police" have gotten burnt by BellSouth, and may be in the process of getting burnt by ATT. One hopes they learn from it. One point of view about this. If you were a policeman, and wanted to contact someone in a phone company, who would you call? Right, the *security guy*. Back in the old Marx Brothers movies, they were called "House Dicks". So now we have the police calling up their *security guy* at the phone company and saying "How can I identify a burgler?" Do you think they would get the same answer as they would get from Pat Townson, Gene Spafford, or even Robert Morris (take your pick of jr. or sr.)? I don't. Oops, sorry. Too long. But I own a "Wonder Bar", a couple handguns, and I recently bought over the counter some hollow point cartridges, and now wonder if these are "dum-dums" in police terms. I have to assume that since the "Wonder Bar" never leaves home, the pistols are at home or at the range, or in between, that I only have to worry during the "in between". Sigh.

In the original incarnation, telegraph was an "express mail service", where you took your (short) letter down to the railway station[*]; the telegraph operator sent the message in morse code down the line, until it wound up in the destination city, where it would get transcribed on paper and be delivered by messenger. In order to deliver the message, it needed to contain the destination street address. Since the messages were charged by the word, this could be quite a significant fraction of the cost, as well as being cumbersome and error prone. Thus began the practice of registering one-word "cable addresses", such as "Tribune, Chicago". I.e. the address would be just one word besides the destination city name. Since this produced less revenue for the cable carrier, they charged for registering the address. When TELEX was introduced, it was first used as an update to the implementation of the telegraph system. TTYs operated on point-to-point lines, and operators carried punched tapes across the room for the next hop of the journey of the message. This was faster than morse code, and required less operator training. Later, automated circuit switches (imported from the telephone world) allowed end-to-end connections, for the duration of the message, and allowed the wire carriers to lease terminals to subscribers for installation on their premises, similar to telephones. This must have happened in the 1940's or thereabouts. While the storefront small-user service remained unchanged, it was at that point merely an emulation of the old user interface; the whole system ran internally on dial-up TELEX service. When I lived in Denmark until ten years ago, the post office still offered telegram service, complete with messenger delivery. You could also phone in telegraph messages, and they would be charged on your phone bill, in the same manner as operator-assisted long-distance telephone calls. There was a SEPARATE service offered by the phone company, called "phono-telex" which was cheaper, for submitting messages to telex subscribers; i.e. there was no messenger involved. By the 1970's, old fashioned telegrams were only used for formal greetings to formal parties, such as weddings, confirmations, anniversaries, cityhood anniversaries, ship launchings, party congresses etc. For such occasions, the Postal Service offered formal "celebration forms" with art prints in various styles. I recently heard that the old fashioned telegraph service has now been completely abandoned, but at the same time souvenir covers are now offered as a delivery option for special delivery fax messages. The more things change, the more we get to appreciate the funny ways in which history survives. [*] The railways needed telegraphs for co-ordinating operations; it was natural that they should try to make a business out of excess capacity. But as the telegraph business grew, it apparently was spun off. I often wonder if the "Western Union" company is not really a railway company that has stopped running trains. Pat, do you have a piece on the history of WU ? / Lars Poulsen, SMTS Software Engineer CMC Rockwell lars@CMC.COM [Moderator's Note: There were numerous small telegraph companies all over the United States in the 1860-80 period. A group of investors began buying them up, using a lot of the same tricks -- uh, excuse me, I mean 'business techniques' -- Ted Vail would use a half century later to grab up hundreds of tiny telcos everywhere for his 'one way of doing things' Bell Telephone System. It was this merger, or 'union' of many telegraph companies, all of whom would be sharing their lines and facilities which led to the organization we call Western Union Telegraph Co. The fact that there were few competitors left in the United States attested to their success in monopolizing the market. Just as Ted Vail and his pals began an agressive effort to grab as much as possible once the patents on the telephone expired -- which forced them to deal with competitors -- so Samuel Morse and his partners wasted no time once Mr. Morse's patent was due to expire. By the time the telephone was invented, Western Union was already a huge organization. Unlike Alex Bell's first message on the telephone, ("Watson! Come here, I want you."), the first telegraph message from Samuel Morse to an associate was "What Hath God Wrought?" Indeed.

You don't suppose they never heard of "mail order"? Besides, I thought all of this was under the auspices of the FCC, and that states and municipalities had no jurisdiction over the airwaves. And, once again, what about continuously tuned radios? By the time everyone gets their "protected" status, the only kind of receiver the public will be able to buy will be for broadcast transmissions. Judging from the state of broadcasting these days, it won't be long before interest wanes in these as well. > Don't these people realize that all you need to intercept a cordless > phone call is another cordless phone? True, but with the newer multi-channel, auto-select models, it is somewhat difficult. I have a Panasonic KX-T3900 and an AT&T 5500 that are frequently used simultaneously (the bases sit next to each other) and they never, ever experience mutual interference.

I would really be interested in knowing what kind of brain-dead PBX could be used to serve a large enough operation where one could hope to get away with this. Every system I have ever dealt with (AT&T, Rolm, ITT, Mitel, Siemens, Toshiba) clearly identifies to the attendant that an outside call being transferred back from a station is just that-- a returning outside call. It does not appear as an "inside" call. Giving that caller an outside line would become a "trunk to trunk" transfer, an option that can be denied in programming. Also, virtually all PBXes, even down to the lowly Panasonics, identify to a station whether the call is from the inside or outside via distinctive ringing. While transferring a call, the destination will have a double ring and when the person doing the transfer hangs up the ring will change to single. In short, it is just about impossible to masquerade as an inside call from the outside. There is one possible exception -- DISA access. This allows a person to dial a special line and then dial within the PBX. DISAs are protected by authorization codes, however, and on most switches still appear as outside calls to inside users, including the operator. John Higdon | P. O.

CO-LAN (at least the version I know about) is a data-over-voice network offered by some of the RBOC's. The user takes a VDM (voice-data mux), plugs it into the phone line, then connects the terminal/PC/whatever and the phone set into the VDM. The unit modulates the data stream above the voice band and carries it to the CO, where it is broken back out by another VDM there and typically fed into a Datakit VCS data switch for access to host services. The VDM can handle input to 19.2K baud. The user must be within three "wire-miles" of the CO for the VDM to be able to successfully drive the line.

Also, since a radio receiver can sometimes receive images offset by twice the Intermediate Frequency (10.7 MHz on the PRO-34, for an image offset of 21.4 MHz), I find it hard to search the 800 MHz public service bands for all the images of cellular calls that crop up there. (You get the image only if there isn't a stronger signal on the desired frequency). The PRO-34's come with the cellular range locked out. Changing the programming to avoid the few cordless frequencies hiding among other stuff would be prohibitive. My opinion on the matter are that other's phone calls are pretty boring and mundane anyway. Most of the cellular trash images that show up are either (1) Ringing tones, (2) somebody's answering machine message, or (3) "Honey I'll be a few minutes late." Federal law prohibits divulging the content in any case, or using the information received to commit a crime (spelled out in big bold letters on the first page of the {Police Call} frequency directory).

Unfortunately, we have encountered problems in processing and applying your 60 minute credit to your first invoice. We have resolved this difficulty and your credit will appear on your third invoice. You may have also received a $10.00 FONCARD (sm) installation fee on the first invoice you received. You are not responsible for this fee and we will be happy to waive it if you will contact our Customer Service Center at 1-800-877-4646. We apologize for any inconvenience this may have caused you. These systems problems were the result of unavoidable circumstances at US Sprint and were not connected in any way to WD-40's participation in this program. US Sprint appreciates your business and if you have any questions or concerns, please contact one of our Customer Service Representatives. Sincerely, [signed] Chris Stanford US Sprint Customer Service <** End of letter **> My comments: Gee, I guess that March of this year is recent enough to be called "recent" ... and seeing that I've never used the card, I guess it is appropriate to say "We're sorry" before you have to call and wait and wait and. I'd just *love* to hear of the "unavoidable" system problem that caused the "difficulty". Perhaps the old, formerly retired Z80 based TRS-80 Model I used for billing in the last decade has been reinstated in their marketing department ... any ideas?? :-) WD-40's participation is disclaimed enough, maybe they put 'em to it.

What do I need to buy (Radio Shack) to do this? -------- -------- |phone |------------------------|phone | | |------------------------| | -------- -------- |ringer| |ringer| -------- -------- MISC INFO: 1) There will be no connections to any regular telco phone lines. 2) The little box's above marked ringer should be small and right next to the phone(s). They should just have 1 button each and ring the other phone(s) when depressed. 3) The box's marked phone should be any phone that can be hooked upto the standard (US) phone system. 4) I understand just a little about how phones work... a) I think its 50-60VAC at 20-30HZ to ring a phone b) phone looks like inf resistance/reactance when on hook c) phone looks like approx 680 ohms when off hook d) there's a small DC voltage when off hook 5) The dial (or push buttons) won't be used (ie just the ringer box) 6) This will be used instead of multiple walky-talkies. USE: 1) One phone will be in the basment and the other 1 or two will be upstairs. I want to be able to signal (via the ringer) and talk without running upstairs or shouting. Besides...its a great project. QUESTIONS: 1) how do I connect tip and ring from each phone 2) what do I need between the phones to act as the phone co. 3) what do I use for the ringer box 4) what do I need to add if I want to hookup a third phone or fourth.

It's a new Phonemate answering machine that records incoming and outgoing messages digitally, without cassette tapes. I've seen machines that used a digital recording for the outgoing message, but this is the first one I've seen that records the incoming messages digitally. Some of the highlights: "Listen to messages at a faster speed without that distorted 'chipmunk' effect." "You no longer have to wait for rewind or reset." "Save, skip, or repeat individual messages with voice confirmation." The ADAM has a built-in phone and is "sale" priced at $200. Speaking of answering machines, I know the Caller ID discussion in TELECOM is closed for the time being, but here's a twist I don't recall seeing discussed. Since many new answering machines tell you the date and time when a call was received, it seems like it would not be much more trouble for an answering machine to have Caller ID built in and tell you the phone number of the caller. Michael [Moderator's Note: Nothing is technically wrong with your idea, except of course that unlike the date and time, derived from the answering machine's own resources, the caller identication would have to be sent from the telco. I'm sure the information sent by telco could be stored on a chip somewhere and read back to you with the time and date. PAT] ------------------------------ From: "Peter B.

I will be in two separate service areas in Maine for several weeks each next month, and the idea of $3/day seems excesssive. Peter B.

But the start up fee and service for one month would probably not save enough over the daily roaming fee to make it very worthwhile. If you do have service turned on there, then simply do your own call forwarding from Chicago before you leave. But if you are only going to be there a month in total, then two local services for a month each, plus start-up fees might even wind up costing more than the estimated $90 ($3 times 30 days) the roaming would cost.

Are you referring to the ability to leave the Philadelphia area and have your cell calls follow you through instructions you send back from some distant point, or are you referring to the ability to be in Philadelphia and receive calls forwarded there from elsewhere? Have you asked the respective carriers in Philadelphia if they offer the service? Some companies, like Ameritech, require an advance subscription to the service, which here they call 'Fast Track Follow Me'. Also, if you have inquired/subscribed, and still cannot activate it, then it may be your serial number is on the denied list, meaning at some point in time some cellular carrier got paranoid about you. You would need to specifically ask customer service to remove this condition.

Since 0055- is the 'premium service' prefix in Australia, equivalent to 1-900, 0898, 0839, etc, it appears that they have set up a service in Australia to avoid international call rates.

Back in June, I had a one-time, first-ever call from one of those COCOTs that does automated-voice collect calls. What I heard when I picked up the phone was a synthesized voice saying "You have a collect call from " and then, as it began to tell me to answer "yes" or press a number or whatever, I hung up the phone. The call had awakened me anyway, and the unidentifiability of the caller added to my annoyance, so I figured that if it was a for-real call, and not a wrong number, I'd get another call. Never did, so I figured it was a wrong number or random dialling by some idiot, and forgot about it. Well, on the phone bill from SW Bell that arrived yesterday was a tacked-on-the-back page from a company called "Integretel, Inc." for a one-minute collect call from (314) 569-3643 at a rate of $2.25, plus 7 cents federal and 13 cents state/local tax, for a total of $2.45. The really insane thing was that it is listed as being from "Ladue, MO". I'm in St. Louis City, and Ladue is a suburb well within the local calling area. A 25-cent call. (It also has a reputation of being a hoity-toity area of rich people, and I don't know anybody who lives there, being a real person myself... :-) Anyway, I called the SW Bell billing office this morning, and the helpful lady there had no hesitation about removing the improper charge from my bill. She, too, seemed surprised by the "Ladue" originating location. I wouldn't be surprised if bad billings from this "Integretel" company were common -- having a name somewhat like "integrity" is a real misnomer, I think; wonder if it would count as false advertising? :-) (She did try to sell me a second line as we concluded the business; I guess that's their current promotion. I didn't need one, and she wasn't pushy, so no problem there.) I think I'll include a letter to SW Bell with my bill, mentioning that she was helpful, and suggesting that it is not in SW Bell's best interest to act as the billing agent for sleazebags like this COCOT firm -- it reflects badly upon their own reputation and image to be associated in any way with AOS and COCOT firms who engage in this sort of underhanded business practice, and whatever small amount they make by doing this is far outweighed by the bad PR effect of SW Bell being identified with these actually-independent ripoff firms. I just called the (314) 569-3643 number, and it rang for about six or eight times, and then answered, and a synthesized voice said "Thank you" (at least I *assume* it said "thank" :-) followed by some rapid tones -- I think DTMF. Then nothing until it disconnected. Anybody out there who feels like calling this and reprogramming that COCOT to burst into flames or allow free calls to anywhere, please feel free to do so... :-) Anyway, I'm posting this as a caution -- even if you hang up immediately on these collect-calling COCOTs, it looks like they will try to stick you with the bill. Maybe the best solution is to find such phones and use them to make collect calls to other such COCOTs, so that the companies bill themselves, and each other, for those calls. A few million such uncollectible billings will do wonders to their viability. Regards, Will Martin [Moderator's Note: And you know what else is frightening? There are live operators from outfits like International Telesphere who perform AOS duties for some of the sleazebags. They will call and advise you they have a collect call from whoever -- and it may be someone you know and what to speak with -- but the operator will NOT tell you it is from a COCOT via an AOS. She will merely say "this is the operator, I have a collect call from Joe Doe, will you accept the charges? Caught off guard, of course you say yes. Then the next month you get *that* on your phone bill; and it may be $10-20, depending. Whenever you receive a call 'from the operator' ALWAYS ask "operator, who are you?" An AT&T or legitimate local telco operator will always identify themselves and the place where they are located. If the operator either refuses to give a straight answer or admits to COCOT/AOS affiliation, then quickly say, "Joe find an AT&T phone to call me," and hang up. Obviously, deny any charges which may show up. We telecom enthusiasts know about this sort of thing; can you imagine how badly the general public is getting ripped off by divestiture?

(Mine left pinky really hurts when I have to crank that darned dial all the way around to 0, so I need to pause a couple of seconds before I can regain the strength to release the dial.) Can we drop this topic now? Does anyone know of any gadgets for a Novatel phone that would allow me to plug a standard jack into it and use a portable terminal? For those of you that have a Novatel phone, it's pretty easy to program. Just lock the phone with the fcn-lock command, and unlock it with #259. Hitting the volume button steps through the options, the SND (spend) key toggles any binary (SET/CLR) options and the END key saves options and reboots the phone.

Grieggs) Organization: Jet Propulsion Laboratory, Pasadena, CA I recently acquired an AT&T portable phone. I do not recall the specific model number, it is the one with two switchable channels. The problem is that the signal quality degrades rapidly, even within the house. Two rooms away, people who talk to me complain about the signal quality. I get crackles and pops, and sometimes some crosstalk (although never clearly), as well as a pretty high level of hiss. This is maybe twenty feet or so from the base station. Also, when I go anywhere near the computer room, it gets much worse still, to the point of being un-usable. How can I boost the power of the phone? Is there some modification I could make to the phone or the base station to increase the signal strength? Would a longer/better antenna on either the base station or the phone itself help? If so, where would I get such a beast? What about the interference? Would more signal strength help punch through this? Or, should I be looking at a line filter of some sort for the computer itself?

Since the indictment specifically talks about Unix systems, this is simply false; without the sysadmin's (root's) permission you can't modify executables in the public directories. In the case of "su", the executable file *must* be owned by root, so the sysadmin would have to be grossly negligent or act willfully to let an ordinary user alter it. This may or may not make a difference to the case against Leonard Rose, but it reflects a view of the world that ascribes great powers to those with technical knowledge, powers they (we) simply don't have. It's that view of the world that threatens us with the labels "hacker" and "phreak" simply because we program computers or read the TELECOM Digest. ------------------------------ From: Jose Diaz-Gonzalez Subject: Looking For V.35 Board With Unix Driver For Sun 3/160 Date: 17 Aug 90 18:11:34 GMT Organization: GTE Laboratories, Inc., Waltham, MA Hello there, The subject line says it almost all.

Berch" Subject: There *is* a Difference I have been following the Sprint (etc.) bashing here in TELECOM and elsewhere (misc.consumers) for quite a while with a bemused smile, since I have never had reason to deal with US Sprint with regard to LD service (data communication has become another matter, alas, since US Sprint took over Telenet, but that's another story for another time). Over the next week or so I expect to be making a number of calls to Paris, France. I am a satisfied customer of AT&T LD, but brand loyalty goes only so far and if Sprint's or MCI's international service was much cheaper than AT&T's I'd certainly give them a shot, so I thought I'd start by making rate inquiries. The following transpired: AT&T ---- Me: [Dials '00'] AT&T Oper: AT&T, may I help you? Me: I'd like the direct-dial rate from California to France, please. AT&T Oper: Yes sir. There are three rate periods. The current rate is [rate info followed...] MCI --- Me: [Dials '10 222 0'] MCI Oper: MCI... Me: I'd like the direct-dial rate from California to France, please. MCI Oper: Oh, I'm sorry, you'll have to talk to Customer Service. I'm just an operator. Would you like me to connect you? Me: Please. MCI Oper: [Puts call through.] MCI CS: Thank you for calling MCI customer service... Me: (Asks for rate info, gets straightforward answer.) US Sprint --------- Me: [Dials '10 333 0'] Sprint Oper: US Sprint, may I help you? Me: I'd like the direct-dial rate from California to France, please. Sprint Oper: Oh, we don't have rate information. You'll have to call Customer Service. Would you like the number? Me: Please. Sprint oper: (gives me the 800 number) Me: [Dials '1 800 877-4646'] Recorded voice: Thank you for calling US Sprint, [blah blah, lengthy spiel with voice menu], "press 2 for a customer service representative," Me: [Dials '2'] [FIVE RINGS] Recorded voice: All US Sprint customer service representatives are presently assisting other customers. Please remain on the line... *** [8.5 MINUTES OF MUSIC-ON-HOLD] *** Sprint CS: US Sprint, may I help you? Me: I'd like the direct-dial rate from California to France, please. Sprint CS: May I have the number you're calling from? Me: It would be Mountain View, California. Sprint CS: I need the number. Me: (gives him a random number from our Telebit modem bank) Sprint CS: Yes, and your name please? Me: Look, I don't have an account with Sprint. I just need the rate information. Sprint CS: Well, I need a name for the billing inquiry. Me: It's not a billing inquiry. I just want to know how much it costs to call France. Sprint CS: Uh, OK, I guess I could do that. The rates are as follows... (gives rate info). *** The point of all of this is that even a trivially simple customer service question can be responded to with a rather broad spectrum ranging from the efficient and professional to the totally ludicrous. It also convinced me that I have absolutely no desire to do business with US Sprint, since it appears that if I ever have any problems requiring customer service intervention, not only will I have to wait a long time on hold at an off-peak hour, but I will then have the joy of speaking to someone completely unhelpful. By the way, the rates differed very little among the three companies; in the lowest rate period AT&T was $0.65/minute, and MCI and Sprint were both $0.64/minute. Michael C.

The blurb below: "Think of how much more productive you could be with a cellular phone." Uh, what's wrong with this picture? Let's see. I could spend .60+/min to use my cellular phone (plus roaming rates, etc), or I could pick up the pay phone right behind me and spend .25/min or less. Top two uses of a cellular phone based on my accidental tuning of cellular frequencies: 1) Person A claiming that Person B doesn't understand him/her and wondering when the next time he/she could get together with Person C. 2) Cellular salescritters talking about the latest rate increase and the kickbacks their getting from the carriers.

The age-old problem: bursts of static which destroy my connections and cause much misery. My equipment is not at fault; it has all been checked out and reconfigured, and the static problem seems to affect many farflung people on YaleNet. I have brought this problem to YaleNet front-office people (probably a mistake in and of itself), with little reaction. The static is hardly noticable during conversations ("I don't hear any static, sir") but reduces me to 1200 baud or less with some regularity. Many many phone calls and one "service visit" later resulted in my being told "We just rent you the line and give you a dial tone ... we make no guarantee of quality." Since the YaleNet fees are fairly stiff, this is not what I expect to hear. My plea: If anyone with experience twisting arms of University telecom types would drop a line suggesting a course of action, I would really appreciate it.

FACTS: 1. In the US cordless telephone are assigned (by the FCC) a portion of the RF spectrum on a shared, non-interference basis only. 2. Power output is likewise severely restricted. 3. Given the above, performance is typically poor particularly in a high-RF environment such as a modern office. OPINION: 1. The "range" listed (typically 700 or 1000 feet) is very optimistic. In the presence of flourescent light PCs etc it is more like 100 feet. 2. The only legal way of improving range is higher gain antennas. Valor makes a large whip plus ground plane arrangement with an alligator clip at the end of the coax to connect to base antenna. We installed one in a hallway and outside the building. Performance improvement was nil. 3. None of this is likely to improve until new technologies such as Spread Spectrum and the like are implemented as in CT2 and PCN trials ------------------------------ Organization: Green Hills and Cows Reply-To: John Higdon Subject: Re: Help Needed With AT&T Portable Phone Date: 17 Aug 90 15:13:55 PDT (Fri) From: John Higdon "John T.

If so, where would I get such a beast? It seems that about twice a year these questions come up. First, your cordless phone is not a cellular phone; it has some distinct and serious limitations. It is amazing how many people expect cordless phones to be perfect. Cordless phones fall under two sets of rules: Part 15, which covers the RF part of the phone; and Part 68, which addresses all the normal phone/network stuff. Any tampering with the transmitter in either the hand unit or the base will render the Part 15 certification null and void. This also applies to the antenna, however since the antennas are already optimized, tampering with them generally simply results in degraded performance. > What about the interference? Would more signal strength help punch > through this? Or, should I be looking at a line filter of some sort > for the computer itself? This isn't the answer you want, but sometimes an environment isn't suited for a cordless phone. While the Ministry of Information won't cut a hole in your roof and haul you away in a straight jacket for modifying your scanner (receiver), the FCC can sometimes get nasty about unauthorized modifications to devices that EMIT RF in normal operation. Cordless phones run at the limits prescribed; increasing anything on them is an FCC rule violation. BTW, 25-30 feet is about all you can expect from a cordless phone in an electrically hostile environment, such as the one I have here. John Higdon | P. O.

In Germany, the ICOM R1, which is a receiver with a range of 100kHz to 1300MHZ (in most places), is sold with a VERY restricted range, 13.95 to 14.5MHz, 28-29MHz, 144-146MHz, 430-440MHz, and 1240-1300MHz.

All LD charges go through ROA .... I'm about as deep into "Southern Bell Land" as you can get (South Florida), and my billing operates precisely as described in the Moderator's Notes. I have two lines that are separate accounts, but BILLED to one line for convenience. When I started up ROA, I gave AT&T the second number (the non-billing one) but have the ROA rates on both lines. Each bill shows a full breakdown of all ROA-eligible calls, grouped by number, and a "total" ROA charge which includes all eligible calls made on either line. According to the folks at AT&T, the criteria is purely the "billing" arrangement. From discussions with them, it seems that I could apply the ROA rates to any number of lines for a single fee, as long as they are all BILLED to a single number. That obviously works out in my favor, but is a bit surprising, since the billing arrangements are not made with AT&T, but with the local telco. I did notice several occasions where calls made on the first line were charged at the standard rate, but I *always* received a "credit" on the next month's bill for the difference between the actual charge and the charge that should have been applied using ROA rates. At least, I assume it was the correct difference, I never bothered to figure it out. The impressive thing (to me) was that I got the correction and credit from AT&T automatically, I have NEVER had to call and question the bill! This hasn't happened for quite a long time now, though, so perhaps they have a different system for figuring it all out these days. My other lines are also billed to a single number, not the same as the first two I mentioned, and are not included in the ROA plan. In the summer months, this results in a monthly "reminder" from AT&T that I could be saving money by using ROA on those lines. I have never felt the need to do this, but I'm curious as to what happens if I simply call Southern Bell and arrange to have ALL the lines billed to the same number as the first two. I am fairly certain that's not EXACTLY what AT&T has in mind with those reminders, though! :-) ------------------------------ From: Gabe Wiener Subject: Re: Teletype Marked "Crypto" and Other Found Treasures Organization: Columbia University Center for Telecommunications Research Date: Fri, 17 Aug 90 02:56:25 GMT In article <10953@accuvax.nwu.edu> riddle@hoss.unl.edu (Michael H.

Yes, Austria does charge for local calls. As far as I know, on subscriber lines, local charges start the moment you go off-hook and continue till you hang up again; on older-style payphones you provide your own answer supervision by pushing a button when the called party answers; newer payphones also seem to charge for the entire time you're off-hook. This does seem to be one of the reasons crank calls are less frequent; it does not eliminate them altogether, though. However, I also think that a low occurrence of crank calls is related to the overall social climate; Vienna also has a relatively low crime rate. I am sure that if you find a city with a higher crime rate, say London, Paris, Frankfurt or Hamburg, you will also find a higher incidence of crank calls, despite the fact that in all these cities, local calls are charged. >Anyone have any facts or opinions on the relative rates of crank >calls.

How does the rest of the world answer the phone? Actually, I think the British custom of answering the phone with the number stems from privacy concerns: presumably the caller KNOWS what number s/he has called; but if s/he has dialled a random number, why tell him/her whom s/he has reached? In Austria, and I believe in the rest of German-speaking Europe, residential phones are usually answered with the subscriber's last name; if a visitor answeres the phone, he may just answer with the subscriber's name, or else would say, for exam
