It sounds as though you may have the three-way calling feature on at least one of your lines. When flash the hook for a dial-tone, you are placing the original call on hold. When you hang up the second call, the phone rings to remind you that you have a call on hold. > It looks as though the phone company installed two lines into the > phone through one physical line (RJ-11?) It hooks into a slot labled RJ-14. Same hardware, different connection.

Sound as though you have three-way calling enabled on the line. First, let me show you an easy way to tell, then the explanation for your "problem." To test for three way calling: Call a friend or long-running recording Flash the switchhook (hang up for about 1/2 to 1-1/2 seconds) You should get a dial tone. Next, call another friend or long-running recording. When this call connects, flash again. Now, you should have both connections tied together. Why this caused the ring back: When you thought you hung up, you probably really flashed. To be sure, hang up for over five seconds. Also a flash generally starts the dial tone with a stutter whereas really hanging up gives you an ordinary dial tone. Since you never flashed while the second call was connected, the calls were never tied together and the first call remained on hold. When you hung up, the phone rang back to remind you that you still had a call on hold. To solve this problem: If you don't want three-way calling, and don't plan to use it, have it turned off. (*) Otherwise, get into the habit of hanging up for at least five full seconds. (*) Some workplaces have all lines with three-way enabled. It usually isn't worth the effort to try to have it turned off, since, unlike call waiting, three-way in non-intrusive.

Well, one of the things that it is doing is telling anyone who wants to know badly enough exactly where you are located. Whenever you have that phone powered up, and in communications with a cell, that cell knows that you are there, and the management system for all of the cells knows that you are there. It needs to track you so that it can get your calls to you, but if there is anyone else interested in your whereabouts, they can know where you are too. For example, if you drive from home to work with it on, there can easily be a log made of when you cross from cell to cell. If every Thursday you "take the long way home" and stop by someplace off your usual path (i.e. using a different cell) that can be logged too. Interesting, no? Another point; if you get the book that describes what exact frequencies each of the segments of the cell is working on, and then get something like a nice AOR scanner with the data interface, even someone who is not able to access the cell management data can sit there and not only listen to cell calls, but can do basic DFing (Direction Finding) on them by knowing what the local cells look like, and seeing what frequencies you are on. So, if this doesn't bother you, leave your cell phone on.

Of course, this would be too advanced a concept for telcos. I recently requested three cards from NET in response to their promotion. They did indeed send me three cards. Of course, since we don't want to waste precious natural resouces (integers), they all had the same number. And in order not to upset any one who wants to "borrow" the card, the PINS are, as per tradition, imprinted along with the number. ------------------------------ From: pschleck@cwis.unomaha.edu (Paul W Schleck KD3FU) Subject: Re: Exploring the Telecom Archives: Archives Index, 7-31-92 Organization: University of Nebraska at Omaha Date: Sun, 2 Aug 1992 17:14:29 GMT TELECOM Moderator (telecom@eecs.nwu.edu) writes: > Anonymous FTP is limited of course to Internet sites, and that is a > pity since so many readers of the Digest and comp.dcom.telecom are at > UUCP sites or entirely different networks.

Wasn't there a mail-server archive for this newsgroup at lonestar.org? Did it go away for some reason or another? The problem with the ftpmail@decwrl.dec.com server is that it gets so many requests (and has to queue them up whenever some sites are unreachable) that turnaround time is rather slow. In fact, untenable delays to Scandinavian sites has caused decwrl to reject requests to files from those countries (a sore-spot for readers of rec.radio.short- wave who want to access the newsgroup archives at unic.funet.fi). Nevertheless, if you use the command-syntax properly and can live with the three file-per-day limit, it's probably the only way to go for those without direct Internet connections. Another approach (used with great success by Rusty Carruth's Callsign Project or Kent Landfield's NetNews/CD project) is to dump the whole thing to CD-ROM or mag-tape (taking advantage of the fiber-optic-like bandwidth capability of a UPS truck full of magnetic media). Naturally, I'm only in a position to suggest this, as opposed to leading the effort. Nevertheless, I find it hard to believe that there isn't someone out in net-land who wouldn't be interested in this project (considering similar successful efforts with Simtel20 and the Amiga archives at ab20.larc.nasa.gov). Another partial solution is to register the TELECOM Digest FAQ and Intro articles with Jon Kamens (news-answers-request@mit.edu) in his Index of Periodic Information Postings. When these articles appear, they are automatically archived at pit-manager.mit.edu (which has an E-mail file retrieval capability via mail-server@pit-manager.mit.edu). News.answers cross-posting of these documents would be another solution (although I don't know if making the newsgroup even *MORE* popular is an ideal situation). There are at least two or three extremely easy ways of doing this (and only security-through-obscurity precludes me from mentioning them here). If the moderator or the FAQ author want to contact me, I'd be more than happy to provide the gory details. Paul W. Schleck pschleck@unomaha.edu [Moderator's Note: Yes, there was such a service at lonestar.org for awhile, but I have heard nothing from that fellow lately. I've also had various people suggest (and a couple even start working on) WAIS (wide area information server) for the archives, but nothing has come of that. If someone wants to put togther a simple, very limited mail server for telecom stuff, I would even try to maintain it myself in my spare (??) time ... but that would be problematic. Perhaps some site would give me an account for the purpose of an ftp <=> email daemon, and an account from which I could administer it.

We are getting a AT&T 5ESS which will be essentially a private PBX for us, but will be operated by C&P Telephone. They want to sell us ISDN for data, both async and sync. For async, they started out pitching X.25 connections over the 16 kbps D channel on a Basic Rate Interface. It seems to me that this is going to be slower than a V.32bis modem, especially one with V.42bis compression. Then there's V.fast to think about. Today they demonstrated some ISDN terminal interfaces that send data over a 64 kbps B channel. There was an AT&T ISDN phone set with a 19200 bps RS232 interface, a Hayes unit with a 38400 bps interface, and a UDS unit whose interface speed I don't recall. While 38400 bps seems more in the ballpark, at least today, why is the rest of the bandwidth being wasted? Why do none of these units implement something like V.42bis compression? There was also an interesting unit (I've forgotten the brand) that could do 128 kbps sync over two B channels. The Hayes unit could do 64 kbps sync on one B channel. This, at least, is a step up from 14400 bps in V.32bis. Anyway, given the relative prices of ISDN terminal interfaces and V.32bis modems, I wonder if we shouldn't just continue to run analog modems, at least for async data. Then there is no need to worry about the difference between off-switch and on-switch users.

Well, OK. But, as Art Baker used to say on television before many of the readers were born, "You Asked For It". My interest in telephony began when I was taught as a toddler how to use the phone to summon emergency help. The next thing my mother knew was that I had found her address book and was calling all of her friends. I was three years old. I have always been fascinated by the telephone and its switching systems. Thoughout my public school years, I would spend my free time concocting devices that would attach (in complete violation of tariff) to the line and provide value added services (for me, anyway). These things included dialers, bridges, various extension phones for my convenience around the house, etc. This activity led to the parental units decreeing that I was to no longer have access to the family phone. A phone in my name would be co-signed for, but I would be responsible for the bill and under no circumstances would ever be allowed to use the family phone again. I was thirteen years old. By this time, I had cultivated many friends in the telephone company (Pacific Telephone) who were delighted with the notion that "some kid" would be so interested in what many thought was a very boring topic. I gleaned all sorts of information about the switches (mostly #5 crossbar) and was given a lot of gadgetry that was otherwise destined for the crusher. By the time I was in my senior year in high school, the neighborhood was wired for private telephone service and my friends were the "subscribers". There was access to "outside" lines and completely automatic switching internally. A repairman discovering some of my outside plant started a ruckus that would prove to be a turning point. He came to my house, threatening me and my parents with more evil than can be mentioned. He called out his manager. Higher and higher levels of management were called out until finally (several days later) the regional manager stopped by to visit. This gentleman, Don Peters, examined the situation and pronounced that if "there were more kids like this young man here, our society would be a lot better off." My project stayed up. And over the course of the years Mr. Peters' and my paths crossed on a number of occasions. His passing several years ago was a sad day for me. Anyway, on to college where I was to prepare myself for the teaching profession. But that was not to be. A friend of the family had resurrected a classical FM station and I was enthralled. I asked to be given part-time work as an announcer. My qualifications? An intense interest in the music and a music background. I was hired. But the owner (who was also the station's engineer) discovered my other interests which included things electrical. Imagine his excitement when he discovered that he could entrust to my hands the patched up 1946 transmitter and even put me on call for its emergency repair! Well, one thing led to another and my broadcast engineering contracting business was launched. But maintaining broadcast transmitters on remote mountain tops can sometimes get a bit old, so I moonlighted (mostly with my radio clients) as a "telephone consultant". In the mid 70's, CPE was starting to become a happening thing, and most people were in the dark when it came to selecting terminal equipment. Those were the days of the NT SG1s and the Stromberg Carlson E-120s. I even cared for a large OKI crossbar PBX for several years. In 1981, I decided that there was more money in the telecommunications business than in radio so I put the broadcasting business on a back burner and formed a corporation that dealt in the sales and service of small to medium sized business installations. We became the region's authorized sales and service dealer for the ITT System 3100 and grew steadily for a number of years. Somewhere in all of this, I discovered computers and taught myself such things as assembly language programming and other very dry humdrum computer things. But as the telecom business grew, it took more and more of my time. And it took it in ways that were not appealing to me. Instead of being able to "play" with telephone technology, I had to worry about taxes, hiring, firing, managers, sales, promotions, and many, many other things that interested me not. On December 31, 1986, I was out. I went back to radio (to continue eating) and hooked up with another friend who had just been fooling around with another hot new industry: audiotex. This fellow is a hardware wizard. He fabricates the most useful stuff out of parts right out of the catalog. He and another person had made some conference bridges out of a Vic 20 and a bunch of VIA chips. These crude machines were making some people a fortune connected to some 976 lines. Mind you, this is before many people even knew what 976 was. This was the answer to prayers. A company formed producing this type of equipment (but kept small-scale) gave me the chance to exercise my various interests and talents, while allowing growth in any yet-to-be-determined endeavors. Since then, we have graduated to creating and programming what amounts to custom digital switches that perform virtually any voice and switching applications. I finally got to play with computers! Most of our customers are in the information providing business, but we have now sold systems to general businesses for various purposes. So what is it that I do? I never got out of radio. I maintain three FM transmitter plants and one AM. In addition, I handle those stations' telecommunications which involve some medium sized PBXes that have ARS, do bypassing (naughty-naughty), use DID, and have live talk show situations. With associates, I participate in the creation of custom voice and call processing applications in the capacity of programmer. In fact, this evening I just returned from a trip to Reno for yet another installation of one of our switches. As usual, there were some last minute programming changes that were required. And that is about it. There are some gaping holes in this little sketch that anyone who knows me well will notice; and I think they will understand the omissions. Shall we leave it at "boxes of color"? Needless to say, rules and laws are now, and have been for some time, obeyed strictly. But as people at Pac*Bell will tell you, I know those rules very well and push them to the envelope. Non telephonic data: I have kept up my interest in music and am occasionally involved in Bay Area concerts. I am an avid motorcyclist who rides both dirt (for enjoyment) and street (for transportation and fun, too).

Although he and I are within a few years of the same age (I will be fifty years old in six weeks), my 'credentials' come from a different type of work-related experiences. A short summary of how I got here: My paternal grandparents were born in Tulsa, Indian Territory. They saw it become the state of Oklahoma, and moved to southeastern Kansas about 1920 where my father and mother were born and raised. I was born in Coffeyville, Kansas in 1942, and came with my parents to the Chicago area in 1947. In those days of course, just about everyone came to Chicago; rail capitol of the USA; hog-butcher to the world and all that. We lived in a south-suburban area. I graduated from high school in 1960, an above average student with mostly A's on my report cards. I was captain of our school's debate team; president of the Conservation Club; and an occassional writer for the school newspaper. They called on me to operate the movie projector. I was a teacher's pet, and helped plan the special assembly programs we had from time to time. When Ayn Rand's (then in 1957) new book {Atlas Shrugged} was published, I wrote her a letter and asked her to visit our school during the promotional tour she was making to sell her book, and she agreed. I still have an autographed copy of that book and {The Fountainhead} which she gave me the day she came to our school. Afterward the debate teacher Arthur Erickson, Ms. Rand and I went to dinner on the way to delivering her back to Ohare Airport for a flight to the next town. After dinner we sat in the restaurant talking, drinking coffee and smoking cigarettes. Since Ms. Rand and Mr. Erickson both smoked cigarettes, I did also. After all, Arthur was very sophisticated, and I at the age of 15 wanted to be very sophisticated also. 35 years of Pall Mall cigarettes has made me quite sophisticated, don't you think? Ms. Rand had very penetrating eyes. She kept watching me throughout dinner, studying me very closely, and I'd look up from what I was eating to see her staring at me. Finally she said, "You are a very intelligent young man. Too smart to believe in Gott! Why do you believe in Gott?" I have never forgotten that comment from her. Although telephones always interested me and I taught the other kids at school how to abuse the (manual service) pay phone in the cafeteria, I had no real plans to be in that line of employment until 1958 when I turned sixteen and went looking for part time employment to earn money for myself. I wound up with a job at the University of Chicago in the old telephone office they operated on the sixth floor of the Administration Building at 58th and Ellis Avenue. I worked there as a switchboard operator part time evenings and weekends during the school year and full time during the summers until I graduated from high school, then full time for another year or so. After high school, I was the solo person there on the overnight 11 PM - 7 AM shift in charge of the three switchboards (main campus, UC Hospitals, and the Computation Center); the telex machine, etc.). They had as I recall a *fourteen position* manual switchboard with a bunch of ladies there during the day and early evening hours then a guy there all night who I replaced when I started full time after graduating from high school. When I first started there, a lady by the name of Muriel Beadle took a motherly interest in me. She was the wife of George Beadle who was then the president of UC. One Sunday afternoon Doctor Beadle came by the phone room and offered me a four year fully paid scholarship to UC when I finished high school. Because I was such a smart-ass who knew so much more than anyone else, I turned it down. Neither of the Beadles spoke to me after that. Those long overnight shifts were very boring to me and I stayed awake devising what I was certain was the most absolutely perfect and fool-proof way to make free international long distance calls. I'll spare you the details of the scheme; it involved the use of telephone credit cards and saying certain things to the international operators at White Plains, NY to decieve them. After a particularly warm Saturday night in August (the phone room had no air conditioning then; it had several ceiling fans which whirred overhead all the time and we left the windows open), 6:30 Sunday morning was a welcome relief as I plotted my schedule for the day. I had tested my 'free international calls' scheme further, and found it to work nicely -- so I thought. A stop for breakfast on the way home; a shower; meet mother at church; go out and sleep on the beach all afternoon allowing myself to be admired by passers-by, etc. Grateful the two ladies who worked Sunday mornings had come in a little early, I took the elevator downstairs only to have a rude confrontation with two impeccably dressed gentlemen who were waiting for me. The one spoke up first, "I'm (name forgotten) from AT&T Security ...", and (gesturing to the other man) "this is (name forgotten). He's a Chicago Police Officer." Their ID's were displayed, and my day was ruined. My resignation was requested the next morning, and given, but the most humiliating part of the whole thing was the next issue of the campus newspaper {The Maroon} with a headline "Campus Phone Operator Arrested on Phone Fraud Charges" and a story with all the lurid details. I then worked a couple years for Commonwealth Edison in the phone room on the midnight shift; and about the same length of time for the (now long demolished) Grand Central Terminal in the Communications Department. I had a few part time telephone operator jobs during the same period including the Lawson YMCA. I answered an ad for supervisor of communications services at Amoco Credit Card Center in 1967 and got the job. It was an old three-position manual switchboard which was converted to Centrex right after I started there. I stayed with them eight years through their management of Diners Club in addition to their own credit card. The last three years I was there I helped oversee the installation of an Automatic Call Distributor in their Sales Authorization Unit and was the manager in that department on the midnight shift. Diners got situated at their present headquarters in Denver and in 1975 Amoco moved the credit card operation to Des Moines, Iowa. They offered me a great deal of money to go along, but at the time I still actually liked Chicago and turned them down, deciding to go into business for myself. The last two years of my employment with Amoco I spent my days working at my business and my nights working at Amoco. This was during 1973-75. I started operating a bank of phone lines with recorded information on the number 312-HArrison-7-1234. The whole thing was sponsored by merchants whose messages came in the first fifteen or twenty seconds of the program. I was so successful at it that after a few months I had expanded to more than a dozen recording machines all hooked up in a hunt group. I used real big, very heavy recording/playback machines I leased from Illinois Bell. The way I had them wired up, IBT had to write a special tariff covering my situation. Whenever executives of other telcos visited their counterparts at IBT, I was included on the schedule of customer installations to be toured, and these guys would come over from telco to look at the setup, prod at the internals of the machines IBT was leasing me, etc. Trouble is, I had a hard time getting paid by my merchant advertisers; I wound up four thousand dollars in debt to Illinois Bell and closed the operation in 1976. I finally got IBT paid off a few years later. After that, I floated around for a year at a variety of jobs and found nothing I really liked. I wrote a few short articles which I sold to the {Christian Science Monitor} at one time or another in the 1970's. Those people were always very good to me, starting when I was in high school. Arthur Erickson introduced me to the {Monitor} and when I wrote them to get a subscription for our debate team they sent it at no charge for a couple years. After I left Amoco and was *very short* on cash one month to pay the rent, the {Monitor} bought a couple essays and sent me a few hundred dollars. Most of the stuff I sent them they bought; the CSM kept me in beer and cigarette money for several months during the year after I left Amoco and my little telephone recorded announcement business failed. I 'got into' 'home computers' in 1977 when I purchased my very first computer: An Ohio Scientific Model C-1-P with all of 4K RAM. You loaded it with a cassette tape. An Apple ][ + followed a couple years later. I had one of those so-called 'Black Apples' which had been made for Bell & Howell in a special order at one time and later were sold as surplus. I still have it stashed away in a closet here. I went on-line in 1980 with a Hayes 300 baud Smart Modem and a Zenith-Heathkit H-19 terminal I built from a kit. I ran a BBS on the Apple called "Think!" (based on the old IBM slogan) for about a year in that time period. The Chicago Public Library started a BBS program in 1982 and I was the volunteer sysop for that endeavor for about a year. I've been a volunteer for the Chicago Public Library for about a decade, but the past nine years of that has been in the visually handicapped reading service which is done over the radio waves on an SCA system; the service is known as Chicago Radio Information Service (or CRIS for short) and it operates on a sub-carrier of WBEZ, our public radio station here. I produce programs on Chicago history, using a variety of printed matter including newspapers, books in the library and various periodicals. My half hour productions are aired three times weekly. I operated another BBS called "Lakeshore Modem Magazine" from 1983-85, also on the Apple ][ +. I wrote most of the software for that BBS myself using Microsoft BASIC and routines for a Hayes 300 baud modem. Starting in 1977 and continuing through this date, I've worked part time (about 8-10 hours per week) 'looking after' the phone system for a department store in downtown Chicago. I usually stop in two or three evenings per week for a couple hours to put through changes in the system configuration, review the phone bills, etc. Sometimes instead I go by on Sunday afternoon for a few hours. I started working for the attornies in 1985 at a variety of tasks including looking after the phone service for their three offices in Chicago, New Jersey and California; but that requires only a small amount of my time. Usually I am working with the clients of the chairman of the firm; his specialty is in the field of commercial collections on an international basis, so I spend much of my time making international calls to companies around the world which owe money to other companies, pursuing the settlement of their account with our clients. One of my most interesting files recently involved a client in Hong Kong who was owed $74,000 by the US Army Post Exchange at a US military base in Germany. A company in Hong Kong owed money by a bureaucracy in Germany asks an attorney in Chicago to look into the matter ... :) and I collected it through lots of phone calls and some persistence. And that is a little of my life ... I hope the original questioner is satisfied now.

SW Bell Wants to Offer Call-Blocking Services By Mary Lenz Post Austin Bureau AUSTIN - In about a year, some customers of Southwestern Bell Telephone Co. could have the ability to reach out and _not_ [italics in original] have someone touch them. The telephone giant has asked the Public Utility Commission to let it offer services which would allow a customer to identify the source of an incoming call and block it if desired. But the Office of Public Utility Counsel has raised privacy questions about the service, and the Texas Attorney General's office said the device used to display information on the caller could be considered illegal. Company spokesmen said the services, which could be available in Austin early next year and Houston and other major Texas cities by 1994, will deter crank callers and obscene messages. Not unexpectedly, the convenience of avoiding unwanted calls has a cost. A Caller-ID display device that would identify the caller must be purchased, for $50 to $150. The annual service cost would be $90 for residences, $240 for businesses. Installation would cost between $2.70 and $5.40. Ron Dusek, of the attorney general's office, said the device needed for the service could be classified as a "trap and trace" instrument, which would make it illegal under the sate's wiretap law. He said Southwestern Bell should test the law in court, or try to have the Texas Legislature change it. The company also wants to offer a service automatically blocking all calls from people who do not identify themselves. Anonymous Call Rejection would cost $12 per year if subscribers take the other extra service. It would cost $36 annually if bought separately. Bell would offer law enforcement organizations and groups with special privacy concerns, such as battered women's center [sic], a free feature which would prevent identification. Copyright (c) 1992, {The Houston Post} Reprinted by permission. ------------- The article did not address a Caller-ID blocking feature other than the last paragraph. I spoke with Ms. Spradley w/SWB in Austin about this: free per line to the indicated agencies, free per call blocking to all other customers. As is typical, this will only work within particular service areas: Katy (an outlying city) while part of the Houston EMS area is not BOC. Calls from Katy numbers will show "number not available" or something to that effect. The PUC tariff control number is 11362.

Prior to the advent of billing computers and automatic time-keeping, all long distance calls were recorded on little slips of paper about the size of an index card with blanks for the calling number, called place/number, person requested, time call was put up and taken down and the operator's number, plus a ticket serial number. The long distance operators filled in all the details except the starting and stopping times. The ticket went in a slot on a small clock which stamped an imprint for that purpose. Starting time on one side of the ticket; flip it the other way to stamp the time finished. The operators did not calculate the number of minutes or the charges. This was done by clerks who came around every few minutes with a basket or box to collect all the tickets which had been stamped out. If the ticket was flagged for a time and charges quote, then it was put aside so the clerks would catch it; compute it right away and call it back to the hotel, etc. One group of clerks did nothing but figure out the minutes and the charges using tariff books, and another group of clerks continually went around posting the charges to the proper customer's 'jacket'. The 'jacket' was a file-folder suspended from a rack with several thousand others in rows in the business office. If you called the Business Office, the representative who answered you was wearing a headset with a fifty foot cord on it. She would walk around the room to the aisle where your jacket was hanging and get it down to stand there and talk to you about your account. Since the posting clerks worked 24 hours per day, a representative might be talking to you and a posting clerk would walk up to her, take the file out of her hands, jot down a new charge, drop the ticket in the file and hand it back to the representative. They worked in tight quarters, so personal hygiene was a must. :) Or if it was the day your account was billed, the representative might not find your file at all .. it would be 'in bookkeeping' ... and the bookkeepers took priority over the service reps, as did the posting clerks. Each day the bookkeepers took several thousand file folders away with them and brought them back a day or two later. A 'jacket' never 'came out of bookkeeping' until the bookkeepers were good and ready. Even the posting clerks had to wait on those file folders to come back before they could post new charges. Operators would sometimes copy down the wrong number to charge, or forget to stamp the ticket out until five or ten minutes after the fact; the subscriber would squawk about the charges and the ticket would go to 'adjustments', where another bunch of clerks would investigate the matter and straighten it out. There were several hundred thousand of the little paper tickets passed around from hand to hand every month ... with a very high degree of accuracy in billing. ------------------------------ From: Nigel Allen Date: Mon, 31 Aug 1992 20:00:00 -0400 Subject: Western Union Money Transfer Services in Canada Organization: Echo Beach Unitel Communications Inc.

It's a bit odd walking into an all-night Dominion supermarket in Toronto and seeing the Western Union logo. I've heard radio commercials for Western Union money transfer service in Toronto. One demonstrates that money can be sent to Jamaica in under an hour. Jamaica was probably chosen because there is a significant Jamaican-Canadian community in Toronto. A Western Union money order is obviously more expensive than a postal money order or a bank draft, but you may not want to risk the delay and risk of theft or loss associated with trusting a remittance to the post office.

Organization: University of Nebraska at Omaha Date: Mon, 3 Aug 1992 03:12:24 GMT As I live in an area which hasn't gone equal access (and won't for another two or three years) 20 miles outside of Omaha, Nebraska, I'm stuck using feature group B (950-xxxx) to access my preferred LD carrier (happens to be my employer as well, but that's besides the point;-) ). Additionally, I live an intrastate, intraLATA long-distance call away from my internet connection, so FGB access enables me to bypass what are Nebr.'s highest residential rates (sidenote: Nebraska LECs have not been regulated by the NE Public Utilities Commission on rates since the deregulation went into effect in 1987 -- resulting in exponential rate increases by small, private LECs such as the one in my hometown of Blair). Unfortunatly, FGB access has given me sporadic noise problems on about 80% of all data calls. Since I'd have to pay an extra $0.20/minute for FGC access (1+) through the LEC, I'd like to determine the source of the noise and find out if there's any solution. If I access 1+, going over FGC, I have clean lines all the way. The schematic looks a bit like this: 1+ access: modem -> Blair Telephone NCR switch -> OMA USW 5E TDM -> univ. switch -> univ. modems (another sidenote: the NCR switch is the early digital model, not capable of ISDN, *70 call waiting disable, etc.) whereas FGB gives me both sending and receiving noise sporadically, (lots of varying text, an occasional }): 950+ access: modem -> Blair Tel NCR switch -> OMA USW 5E TDM -> TZX DEX switch -> OMA USW -> univ. switch -> univ. modems Through some experimentation, I've discovered the following: 1. FGB access through TZX, Omaha to Omaha, using different computers, lines, etc. (never hitting the Blair Tel network) results in the same sporadic noise problem (with the same frequency). Apparently Blair Tel isn't the source. 2. Night data communications over FGB is more prone to noise than day. The switch tech at my FGB LD carrier said I'm going through some pretty ancient switching equipment at our BOC (US West) and indicated that was the likely source of the noise. What I'd like to know is: a) Is this explanation valid? And if so, is this typical of RBOC FGB equipment? b) If it isn't valid, what other variables can be involved that I may be missing? c) If the problem could be the long distance carrier's equipment, any suggestions as to how to demonstrate this to them? (since they're also my employer, all I need is something of substance to counter the switch tech's opinion;-) ). Many thanks in advance!

Date: Mon, 03 Aug 92 00:59:46 -0400 I'd like some advice on how to pick a long-distance carrier. At first, I thought "Aha! This will be easy -- they're fighting for market share, if I tell them I'm interested, they will send me gobs of information. Then I can sit down with a calculator and some previous bills to figure out my calling habits, and I can decide" So, I called the numbers I saw presented in the TV ads for Sprint, MCI, and AT&T. Everyone was very polite, and everyone promised to send me rate information. It's now the proverbial four-to-six weeks later, and (much to my surprise) NO ONE has sent me anything. So, my questions: 1) Is there some organization (perhaps regulatory) that keeps track of LD rates and that I can ask for informaton? 2) Is there a better way to get written information on rates? (The ld*.txt files at lcs.mit.edu are great, but they're from 1985). 3) Is there any way that my apartment's phone can be used for more than one carrier without paying calling card surcharges? 4) Are there any factors that I should be considering other than rates during my planned (late-ish) calling period? 5) Are there any other carriers that I should be considering? 6) Is there a source (electronic or paper) that I should be RTFM'ing about this? 7) Someone on this list mentioned an inexpensive personal 800 number service. The rates sounded comparable to what I'd been told by various LD folks, and I could arrange to have people I want to talk to call me and then split bills. Is there some reason why this isn't viable? 8) Is there a substantial difference between the cheapest plans of the three majors? I would be grateful for answers to any subset of these questions. If your're getting a great ld deal that you want to tell me about, that's fine too. I'll post a summary in a week or so. david ------------------------------ From: jim!mike@wupost.wustl.edu (Mike Suter) Subject: Tropez 900DX Organization: BITS, St. Louis, MO Date: Mon, 03 Aug 1992 16:34:46 GMT I caught the (very) tail end of the recent discussion on the Tropez 900 digital cordless phone.

AT&T has been issuing a Universal Card (a MasterCard or Visa combined with a Calling Card for a while now). Ameritech issues a Complete MasterCard (a bank card that includes a calling card, although people living outside Ameritech's service area don't get the calling card). A few questions: Have any other telecommunications carriers gotten into the bank card business? Montreal Trust, which is owned by BCE Inc. (the parent company of Bell Canada, Northern Telecom and assorted other telecom companies) issues a Visa card, but it's been around for decades and offers a relatively full range of banking services. I have a CNCP Telecommunications credit card which can only be used to charge telegrams and Telepost (the Canadian counterpart to Mailgrams) messages. I have no idea if it's still good with Unitel; for some reason I haven't wanted to send any telegrams lately. (Canadians reading this post may want to set up a monthly telegram account with Unitel just for the fun of it. Call the local number for Unitel's telegram service and say that you want to set up a monthly account.) If you would like to apply for an Ameritech Complete MasterCard, call 1-800-723-1000, ext. 1000. According to an Illinois Bell publication, there's no annual fee and the interest rates are 14.9 percent for balances of $2000 and up, and 17.4 percent for balances below $2000.

"Telekom" runs the phones. Telekom was fairly recently separated from the Post office but it's still a gummint agency. All costs are in D-Mark; conversions are based on the exchange rate of US$ 1 = DM 1.50 to make the math easy (actual rate 1.477 or so). Installation cost 65(US 43) and it doesn't matter if they run wire or not. They require no deposit in advance. We placed the order in person at the phone store, and three weeks later a fella arrived with our phone. This was apparently fairly quick. Seems that Telekom doesn't send their own people out to do installations but subcontracts it out. The weak (slow) link in the chain appears to be the subcontractors; I'm told that Telekom is quick with service changes. You are allowed to own your own phone, although it's supposed to be a model that's approved by Telekom. Phones cost a minimum of 80 (US 53) in cheap stores, a minimum of about 100 (US 67) at the phone store. We chose to rent ours from Telekom for about 3.50 (US 2.33) per month. Our phone does touch-tone and stores the last number dialed; i.e., it's the basic 100-Mark model. Judging from our first bill, monthly service is about 52 (US 35). They make no distinction between touch-tone and pulse dialing, as far as I know. Our phone had to be told to send tone, and the switch understands it fine, but I don't think that I requested it specially. The monthly service includes 15 message units. Additional message units cost about DM0.23 (US 0.15). Now a brief digression to explain message units as understood by Telekom: Every call is metered. Local calls cost one message unit for every six minutes during the day (6a-6p) and 12 minutes at night. Long-distance works by varying the length of time you get for one unit. Domestic long distance is also discounted 50% at night, but international calls cost the same 24 hours per day. Ferinstance, when I call other cities during the day, a unit gets me about 30 seconds to one minute, and I assume double that at night. When calling the USA, a message unit lasts 6.67 seconds; this works out to almost exactly DM 2 (US 1.30) per minute at all times. As was posted here previously, Telekom recently increased the time from 4 to 6.67 sec, possibly in response to heavy competition from USA Direct etc. Information costs the same as a local call (i.e., no extra charge beyond the time) and will give you a number anywhere in Germany. Oh, I almost forgot! There doesn't seem to be an operator here! I had trouble calling Koblenz one day (bad connection) and wanted help dialing, but there did not seem to be any way of getting help. I even called the damage-report people and they weren't too helpful. That's about all I can think of. Hope this interests some people. All in all the service is good, although the long-distance is really, REALLY expensive when compared to US rates. Especially considering that the distances covered here are small compared to the States! As a prior resident of the huge LATA in Maryland/DC/Northern Virginia, this heavily metered service strikes me as kinda expensive. I had forgotten how much we depend on a phone, but those three weeks without really refreshed my memory! chris ------------------------------ Date: Mon, 03 Aug 1992 01:27:15 EDT From: JOHN SCHMIDT Subject: Analogue Problems With Digital Switches I guess the people who design the digital PBX's (or whatever initials you are using these days) don't pay much attention to the design of the analog line ports. At ABC TV (my daytime, paying job) I am a design engineer specializing in audio and communications installations. Corporate telecommunications just replaced their old "Dimension" PBX with a Northern Telecom one, with the Meridian digital phones. We kept the old 1A2 key telephones in the control rooms, as the Meridian phones are useless there. With the low light levels, you can't see the LCD displays, and you can't interface the phones to other communications equipment easily. (Try a headset interface which also has to work with intercom stations, audio monitoring boxes, etc.) Also they are difficult to configure with automatic ringdown tie lines, and such. Corporate Telecom installed analog line ports to drive the 1A2, and all the other analog stuff, such as couplers, broadcast hybrids, and modems. About a day after cutover I start getting calls from the audio guys in the control rooms that the couplers and hybrids wouldn't "hang up" when the person calling in hung up. The couplers had to be "released" manually (we install a button for that purpose to disuade wrong number dialers and hackers from listening to or (worse) talking to our systems). This was causing the shows a lot of grief, as they (the audio op's) would call in to test the equipment, and then hang up. When the remote crew called in, they would get a busy. The audio op's had to keep remembering to release the line. Anyway, I performed a quick test, which proved that there is no CPC through the analog line ports of the Northern PBX switch. This surprised me, as Adelphi University (where I'm sending this from) has the Centrex version of the switch (one is the DMS1 I think, the other is the DMS100, don't flame me if I messed this up, I'm mostly audio these days, my telcom work was in the days of an ITT pbx, with its own wierdnesses) and the Centrex analog lines have about a ten second timeout before the battery drop. Also the digital ports on the PBX switch have CPC, the line indication on the LCD goes out almost instantly when the calling party hangs up, even from CO or tie lines. I called the Corporate Telecommunications people, only to discover they had the same problem with all their "Quorum" conference bridge lines. We looked in to converting the affected lines to E&M trunks, with E&M to loop start converters (Northern says that the analog trunks, as opposed to lines, do have CPC.), but at $500 or more per line for the converters. Why not loop start trunks, instead of lines? No ring voltage! oh well. In the end, Corporate has had to install a bunch of CO lines to the affected lines. Meanwhile, they have promises from Northern for a fix "soon". There is one other solution for some users, which I found out about from the Telecom Director here at Adelphi. A company called Dees Communications makes a couple of boxes which are stuck in "series" with digital "Meridian" instruments. (you plug the digital line into the Dees box, and the Dees box into the instrument,) One of these boxes has an analog port which can be hooked to a modem, answering machine, loud bell, etc. It can be programmed to answer any or all lines, and can make outgoing calls on a selected line. Another box is programmable to give loud rings on any or all lines, and/or give a contact closure for an external bell/light/etc. I think they make a couple of other varieties. The two above are something like $150 each, I think. They are doing this in cooperation with Northern, and their stuff is distributed by North Supply and other such distributors. Dees is in Seattle, Washington, as I remember. I have two of their boxes installed here at WBAU, one of the "port" ones for a modem, and the "ringer" one in the control rooms, as a visible light, so the DJ's will answer the business lines when no-one is in the office. (the on-air lines here are also 1A2 behind analog ports, that's how I knew the CPC worked on the centrex switch.) John H. Schmidt, P.E.

Organization: Maverick International Inc. Date: Mon, 03 Aug 92 23:48:50 GMT I finally figured out my billing problem. I had been making a few calls to a BBS in Ohio (I'm in Washington, THE STATE) and apparently wasn't getting billed for most of them. This had gone on for a period of about five months, so I wondered about billing problems on the far end or somesuch. Then about two months ago, I connected a spare pair in each room to an A/A1 relay so I could use my laptop's modem in any room on my first line and have it properly light the buttons on the telephones. But, I had a slight short to ground or maybe some "unbalanced" wiring somewhere, and my wife tolerated the humming on line 1 and just started using line two for outgoing calls to avoid the hum, which I did finally get around to fixing. Well, we just got the GTE bill with included AT&T LD, which normally runs about $100 for the two lines plus her calling my inlaws on the other side of the state. But, this last month, there were practically no LD calls on the bill and it was for only about $50. Apparently for the last year, since we moved, we've never been billed for LD calls on line two! Questions: Any guesses as to whether GTE or AT&T messed this one up? How long will it take them to discover this SNAFU, and, more importantly, how long will they give us to come up with the $$$? Anyone with similar experiences? Yes, 1-700-555-4141 still reports AT&T on the second line. ------------------------------ Date: Sun, 2 Aug 92 23:10:19 CST From: Jack Decker Subject: Bell Canada Response to CRTC Announcement The following message is forwarded without comment from the Fidonet MDF echomail conference. Please note that "Zone 89" is not an official Fidonet zone; rather, it is a zone in IMEX, a Canadian Fidonet-technology network, so this message originated in IMEX and not in Fidonet: * From : Rt Pollock, 89:82/1 (27 Jul 92 13:01) * To : All * Subj : Bell-CRTC The following appeared in the Toronto SUN newspaper as the "Letter of the Day" for July 21, 1992. It is signed by one Linda C. Grevais, Director of Corporate Public Relations, Bell Canada, and addresses some of the problems that Bell Canada has with the recent CRTC announcement for a more free spirit of competition in the Long Distance Telephony business.--- "In its July 8 letter to the Toronto SUN, the Consumers' Association of Canada (CAC) objected to a Bell Canada advertising campaign which communicated the message that "Competition in long distance should favour consumers. Not competitors." "The ad campaign pointed out that a recent CRTC decision forces Bell Canada to make massive investments to help its competitors establish itself. We believe this to be an important message for Canadian consumers." "What are these massive investments ?" "To begin with, it is well known that the new long-distance competitors will not be offering local service because it is much too costly to provide. The CRTC confirms in its decision that Bell Canada alone supports low local rates with a $2-billion annual subsidy from long distance." "The new competitors say they will help to keep rates low by making payments to this subsidy from their own long-distance revenues. But these payments will not be sufficient to provide the same level of subsidy. Bell's analysis shows that special breaks given to competitors will result in a shortfall -- there will not be enough to go around." "The new competitors and their supporters claim this will not happen. But their claims are at variance with the facts." "In his research report on this issue, telecommunications financial analyst Robert Hastings, of Richardson Greenshields, describes this aspect of the decision as "a hoax". Hastings says: "How in the world can the telcos swallow over $2 billion of lost long-distance rates as much as previously planned -- without increasing local rates?" " "In addition, simply allowing competitiors into the market will cost Bell $160 million in the next three years. We are expected to cover this cost, and the subsidy lost to competitors. But is it realistic to expect that Bell -- already one of Canada's most efficient companies -- could absorb these extra costs with absolutely no effect on its service or its rates ?" "The face of telecommunications has changed in Canada. Bell says yes to this change. But we cannot agree that the new competitors should benefit at the expense of our customers." -------------- GEcho 1.00/beta Origin: Odyssey Systems: Out In Front In Oshawa Otarion:416-571-4407 (89:82/1) -------------- Jack Decker jack@myamiga.mixcom.com FidoNet 1:154/8 ------------------------------ From: William.Sanders@f-454.fidonet.org (William Sanders) Date: Tue, 04 Aug 1992 20:31:42 -0600 Subject: Looking For 4800 Asynch Modem * Original Area: Swapshop * Original To : All (1:106/665) Howdy!

Recently, there were messages in this digest about 617-422, in Boston, displaying place name of Sterling on my May 1992 phone bill. (Sterling has a 422 prefix, but it went to area 508 four years ago.) My July phone bill shows a call to 303-541 Simla, Colorado. Barring a situation like 717-229 Jefferson (Pa.), Simla is at the post office with zipcode 80835 (and I believe Simla would be in the 719 area now). I thought the number I called on 303-541 was at Boulder, which would have remained in 303 when 719 was formed. The calls cited above to 617-422 and 303-541 were both direct-dial via MCI. ------------------------------ End of TELECOM Digest V12 #604 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa02826; 5 Aug 92 4:51 EDT Received: by delta.eecs.nwu.edu id AA12298 (5.65c/IDA-1.4.4 for telecomlist-outbound); Wed, 5 Aug 1992 02:38:47 -0500 Received: by delta.eecs.nwu.edu id AA30524 (5.65c/IDA-1.4.4 for telecomlist); Wed, 5 Aug 1992 02:37:59 -0500 Date: Wed, 5 Aug 1992 02:37:59 -0500 From: TELECOM Moderator Message-Id: <199208050737.AA30524@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: Internet Services List I recently received the following article from a reader and found it very informative.

Crepin-Leblond Date: Tue, 4 Aug 1992 19:28:27 +0100 Subject: No Fun Anymore! (was Thrills of long-distance) Hello, About a week ago, I recall reading a footnote that PAT wrote regarding the situation of the Internet and comparing it to the situation that happened with ham radio before and after the "CB-people" were born ... Cliff Stoll then wrote: [much stuff edited - ocl] > In 1956, nobody called long distance across the Atlantic. Anyone > older than 40 remembers their first long distance phone call -- with > an eye on the second hand of the clock, you spoke fast. That one > phone call was cherished and packed with information. Not the same > thrill today; not the same information content, either. If you are interested in excitement, then try calling a place like India -- still very expensive and still a real adventure if you want to make a quick call ... ;-) Then comes a short chapter about ham radio. How great it used to be. How great it is today ... NOT! Then a chapter about astronomy and nostalgia about observing at a mountaintop telescope. Now it's all on CD-ROM, etc. etc. Finally Internet/Usenet: > Is the same thing is happening on the Usenet/Internet?

Malicious intruders break into computers. Many > postings have zero content. [stuff deleted to save Mbytes - ocl] Cliff concludes that it seems that with a lot of things nowadays, the Thrill is gone. Add to this message a footnote from our Moderator: > [Moderator's Note: You hit the nail squarely on the head. The thrill > is gone -- it isn't *fun* any longer. And yes, Usenet is the same way. ie: in complete agreement with Cliff. But wait a second, chaps, am I detecting much "nostalgius malignius" here? Your reaction to what's happening in the world today is some sort of rejection of advances in science. Imagine how Farraday would feel today looking at the way we treat electricity. Imagine how Mssrs. Daimler and Benz would feel if they looked at the cars we drive today. How about all of these aviation pioneers? How would they feel crossing the Atlantic in a Boeing 747? If one looks at the world this way, then one would always long for "the good old days" when only the qualified and intelligent would be able to use a service. You must understand that you were pioneering USENET/email/packet transfer of data in the seventies. Indeed, what we are doing today, this global conferencing system via Usenet, is still not available to *everyone* around the planet. In that respect, we are still in the pioneering stage. Just wait until the public at large is issued cheap terminals, or interfaces to exchange such a wide range of ideas as what is being exchanged on Usenet. Of course, being one of the Pioneers, one always longs for the "good ol' days"; it's natural to feel like that, but one thing that is sure is that we can never go back. [Then Pat describes the situation regarding the TELECOM Digest with 200+ messages per day nowadays. (phew ! congratulations for still keeping- up, Pat !) But then comes a statement that I disagree with: - ocl] > 100 per day and sometimes 200 per day -- this group alone.

PAT] CB radio has never been seen as a "serious" means of communication. Agreed, Usenet isn't either. However, Usenet spans much greater distances around the globe than any CB network *ever*. What you have with CB is people living is roughly the same area of the world talking with each other. What you have with Usenet is people from *all around the world* who have the -> Freedom <- to discuss virtually anything they want to talk about. Okay, flames are getting more and more common, but isn't that more a reflection on today's planet society? This internationalisation of a single information medium brings-in the same conflicts as conflicts we are currently seeing in what was Yugoslavia, Irak vs. Kuwait, Jews vs. Arabs, pro-abortion vs. anti-abortion, etc. etc. While netiquette is less and less observed, isn't the situation similar in any country around the world? Usenet brings debating between people of very different background and origin possible. While unfortunately this may sometimes result in a lot of messages containing a "vacuum of nothingness" you'll find that there are some very interesting discussions that spring-up here and there. The negative effects are of course the increase in overall traffic carried by the networks. But if we look at the resources we now have at our disposal, is this increase in traffic likely to strain computing resources more than it used to in the past? My personal guess is no. Storage media size increases in capacity; speeds of transfer of telecommunication lines and fatpipes also increase accordingly, and ultimately, the only people who won't be able to cope with things are us, the human beings, since we'll have an overdose of information being fired at us. But do we know ourselves how much information we can chew-up every day? Perhaps our minds will train themselves into going through so much data. In short, I tend to believe that it is unlikely that sites would pull the plug on Usenet. If they did, then it would be the consequence of erm ... elderly system managers (apologies to Pat et al) [I am using the term "elderly" as opposed to young, ie: 40 years+ - ocl], who would find it difficult to cope with so much information being fired at them. Effectively the brain starts losing cells from the age of 20, so it's increasingly difficult to train it for new tasks, new processing, especially when speed of processing is required. As far as email is concerned, there is NO WAY that sites would pull the plug. My inner belief is that "We ain't seen nothing yet". With ISDN, soon Broadband ISDN, (year 2000+) everyone will be able to use packet-based services. Email may decrease when video-mail will come-up and this will decrease when interactive video telecommunications will be cheap to use. Until that time, email transmission of documents may go as far as replacing faxes, and of course, normal postal services. One thing before I go home: The decade of the eighties was the decade of computers for all. The decade of the nineties will see the same jump in technology as the eighties was in computers, but this time with telecommunications. I hope that I haven't offended anyone on the net. If I have, all my apologies. flames -> devnull as usual. Disclaimer: Affiliation to Imperial College is given for identifi- cation purposes only. Imperial College has no opinions whatsoever.

Thanx to all [(Andy Sherman) (Jon Baker) (26070-adams) (Alan L Varney) (david.g.lewis) ...] who answered ... it was interesting. Geeze, I had not known that 1-800 was almost as old as me! Then of course, MF signalling between the LEC and the IXC all fits into place. An interesting side-knowledge I got was that CallerID was not "everywhere" yet, that was the impression I, alongwith many others here, looking on developments in the US telecom scene across the pond were led to believe! From many cities in India, you can now Call-US-direct. The ads from our government monopoly does not say that this can be done only from certain switches, and certainly not all switches even in our metros as electronic. So, I guess they are using a set of methods to ensure that the call is billed to the card, and not to the calling number. If the exchange is electronic of course, the way to do it is obvious now. If not, I guess the Trunk Exchange (or Tandem as you call it) would just not send any metering pulses down the line, so your meter would not tick. This is my guess ... I plan to find out soon. One thread of thought, (too obscure to mention here :) started off by this in my mind ended up with this question ... How easy is it to start a Long Distance Carrier out there in the US? I know one has to obtain/lease/buy/install long distance ties etc. and establish points of presence, which entails cost/planning. But that IS NOT what I ask about. I mean, what does one have to do from a regulatory point? Any registration? Any prequalification? How does one end up getting a equal access code just like amy other LDC? Does one have to make arrangements with each RBOC/LEC or is that "automagically" done once you are "crowned" a LDC?

Not true, the Trailblazers we have used on out USENET/mail links just go "shhhuuk ... SHHHUUKKKK ... shuuuk ... SHUUKKK", sending white noise like bursts (meaning much of USENET is white noise ? :-) in a ping pong fashion. They suffer from neither drop outs nor from echo suppressor, ... matter of fact they were what, and which was why, kept India on the Internet access across the pond for the first few critical months on a plain, and plain-bad ISD (International Subscriber Dialing) phone line. Of course, it won't take too long to come up with a modem that "talks". shrikumar ( shri@iucaa.ernet.in ) [Moderator's Note: To be a Long Distance Company in the USA, all you have to do is say you are one. No registration (where telcos are concerned; just whatever you would do regards taxes and corporate status, etc) is required. No leasing of lines, etc, unless you find it to your advantage to do so. You can string your own wires for all anyone cares. You can install an elaborate switch or merely grab the incoming calls from your customers and dial them back out over existing lines. If you want a 10xxx code or a 950-xxxx type number, you have to apply for one, and once it is turned on, all carriers will get the update. You have to do your own billing unless you cut a deal with some telco(s) or service bureaus to do it for you. PAT] ------------------------------ Date: Mon, 03 Aug 1992 10:05:57 EDT From: Robert B. Thompson Subject: Ringdown Circuit Hardware Recommendations Needed Due to staff reductions we need to replace a staffed public information desk with an automated voice processing system. This system will provide assistance via voice menu to both local courtesy phone users and to users dialing in on a rotored CO group. We have a PC installed with PowerLine 2 multiport voice cards from Talking Technologies, which handles dial in users with no problem. The courtesy phones for local users are another matter. I need to install a ringdown circuit or circuits independent of the CO and connect POTs to the ringdown circuit(s). When a user goes off-hook the ringdown circuit should establish a loop and generate ring at the voice card. When the user goes on-hook the circuit should drop the loop and disconnect from the voice card. I've seen this type of circuit installed in elevators and security doors, but have no idea what hardware is needed to perform switching and provide ring current and talk battery. Suggestions would be greatly appreciated. Thanks.

Of course, this would be > too advanced a concept for telcos. ... I don't see how a card that generated DTMF tones would be any more secure than the current cards. True, nobody could visually read the number off the card (though, as you point out, simply omitting the printed PIN from current cards would solve this problem), but you'd better not use your fancy new card too close to anyone carrying anything big enough to conceal a tape recorder. (Even if the tape doesn't have enough signal strength to successfully imitate the card if played into a telephone, all the sophisticated crook has to do is decode the DTMF tones into numbers and go from there.) Plus, the "smart" cards would undoubtedly be more expensive to manufacture (which would be reflected in rates), and would be yet another thing in my life to break when I need it most. :) If you want security in your calling card, tape over the numbers printed on it, only use it in phones with a magnetic card reader, and never lose it. (Note that this gives you basically the same degree of security as the "stored value card", with the option of removing the tape and using the card the "unsecure way" if you desperately need to make a call where there's no card-reader-equipped phone.) I don't see how any "solution" that still requires numbers or sounds to be fed or spoken into the phone can be made much more secure than things are now, since anything visible or audible in a public area can be copied or recorded.

Dave, it's true that ACD is the way to go for true mass calling destinations. But it only helps to a point. It will either run out of "queue slots" (good design) or tie up all the incoming trunks to the terminating CO (not good). Then the other 10,000 callers cause the same system overload you'd see if there wasn't an ACD. As I mentioned, the only answer I have come up with for the "mass ticket sale" via telephone is: Don't do it. That's not to say that such a system couldn't be designed.

I'm not familiar with number 5 > internals, having never had the bad taste to live near one :-) One of the problems we experience on our campus Centrex (provided by a US West 5ESS) is that there are many different kinds of "hunting". For example, Call Foward Busy can be used to establish a "hunt goup" but can only be used for a string of about ten lines. For more than ten lines, we order Standard Hunting. Unfortunately, Standard Hunting does not pass ANI data to our voice mail system, so if we want the last line to "hunt" into voice mail, the last line must be equipped with Call Forward Busy. Each of these features is set up differently in the switch, and we are charged differently for each feature. The hunting feature you are probably having problems with is Multi-Line Hunt Group (MLHG). (I don't know how standardized these terms are, this is how we order the features from USW). This is the only feature set that allows USW to do busy studies for us. It also has the option of allowing us to test specific numbers within the hunt group. With the other hunting type features, if you call line three in the group and it is busy, then your call automatically hunts to line four. With MLHG if you call line three and line three is busy, you hear a busy signal, line four is not considered. The only time a call will hunt from line three to line four is if the call originated at line one, and hunted thru lines one, two and three. This allows us to call a specific line for testing, and KNOW that we have that line, and not one of the others in the hunt group. At last I get to the point ... For features like auto call back, this MLHG feature creates problems. Let's say you dial the lead number in the Hunt Group and all of the trunks are busy. The auto call back will attach itself to a specifc trunk, and only attempt to call back to that trunk. Thus the chances of getting thru to that trunk are pretty small. If you call back manually then you get a chance at all of the lines in the hunt group. Unfortunately, then larger and busier the group you call, the more likely it is to be a MLHG. This feature allows for the most flexibility of testing lines, allowing the system administrator to more quickly diagnose problems, and take problem trunks out of service. I should note that I am not a switch engineer, I am user who orders these features for departments within the University of Washington. My understanding is based on explanations given to me by USW marketing representatives and may be over simplified, or mis-understood by me. As a side note: When ordering residential service for two or more lines, many people just ask for "hunting" and get Standard Hunting. In a two or three line situation, Call Forwarding Busy will work every bit as well. In US West territory (at least) Call Forward Busy is about a dollar a month cheaper than Standard Hunting. Unfortunately most of the reps you talk to do not know that two largely equivalent features exist, and only know about the most expensive :(. Be persistent, ask for supervisors. As a side side note, our campus Centrex is now offering Custom Ringing, Call Forward Busy or Don't Answer Programmable Variable, and a host of other neat things. The Bells are finally starting to open those swtiches up a little.

You have to understand that the marketing mechanism for each of the major carriers is geared to the "instant close". The last thing that any of them want is for you to actually do comparison shopping. If you do that, you will discover that there is not much differential between comparable rate plans. Sending out rate information is too much bother and expense for just one POSSIBLE customer. > 1) Is there some organization (perhaps regulatory) that keeps track of > LD rates and that I can ask for informaton? Yes, the FCC. However this information is not all that easy to get on a regular basis. Rates change constantly, just like the commodity market. I have found that an efficient way to keep up on it is to periodically call each carrier and ask for specific rates between two fictitious exchanges. This includes initial minute and subsequent minutes for each of the various plans. > 2) Is there a better way to get written information on rates?

Simply establish an account with each carrier you want to do business with. Only one can be the default, but each of the others can be accessed with FGD carrier access codes (10XXX). It is functionally the same as "dial 1". > 4) Are there any factors that I should be considering other than > rates during my planned (late-ish) calling period?

For instance, if I call Hawaii using AT&T from here, the connection is dog excrement. It is almost not possible to conduct an intelligent conversation. If I use ComSystems, the connection is perfect: no delay, no distortion, no noise. This was found by accident, but is the type of thing you want to be on the lookout for. > 6) Is there a source (electronic or paper) that I should be RTFM'ing > about this? Telecom Archives?

I have found that a standard business 800 offering suits my needs (and pocketbook) better than any of the "personal" 800 services. So be sure you check all the possibilities out, not just the ones that are hyped to consumers. > 8) Is there a substantial difference between the cheapest plans of the > three majors? No. For my own set up, AT&T is cheapest, MCI a close second, and Sprint is out in left field. Since I have found AT&T to have the superior service overall, the choice was easy. John Higdon | P. O.

Yes, NECA is the government regulatory entity that sets tariffs. I am not sure if NECA would send you the rate information, and I not sure you want to get it. Last time I reviewed the NECA tariff volumes I was shocked at the complexity of the NECA tariff manuals. > 3) Is there any way that my apartment's phone can be used for more > than one carrier without paying calling card surcharges? Yes. You can use 10XXX dialing from almost any line to access a non-presubscribed carrier's network for casual calling. The dialing method is: 10-XXX-1-A/C-Number (Example, 10-288-1-515-830-0436 could dial my office over the AT&T network.) The XXX stands for the Carrier Identification Code (CIC). Follows are the CICs of the more known carriers. 001 MidAmerican Communication 450 LDDS Communications Inc 007 TMC Long Distance 488 Metromedia/ITT 222 MCI 555 Telesphere Comm, Inc 250 Dial-Net Inc 754 Sears Technology Svcs 288 AT&T 772 Sears Technology Svcs 333 U. S. Sprint 832 TeleCom*USA 401 National Teleservice, Inc 835 TeleConnect This list is not comprehensive, it is for example only. CICs might differ in your area. You might want to check with your local telco before dialing. Access to some of these carriers may not be available from your area. > 4) Are there any factors that I should be considering other than > rates during my planned (late-ish) calling period? Yes. One of the obvious things is the call duration. The longer you call, the more it will cost you, no matter how low the rate is. If you are in an equal access area, your local telco might be able to provide you with an IntraLata carrier choice as well. In my opinion, chosing a carrier other than the RBOC for your intralata calls can save you money. To my knowledge, Centralized Equal-Access that provides IntraLata carrier choice is currently avialable through only three companies: Minnesota Equal Access Network Service (MEANS), Iowa Network Services (INS) and South Dakota Network (SDN). I understand Kansas, Missouri and Indiana are currently considering CEA as well. CEA is available ONLY in rural (non-RBOC) areas. DR> 5) Are there any other carriers that I should be considering? See list above. DR> 8) Is there a substantial difference between the cheapest plans of the DR> three majors? Personally speaking, I have not noticed significant difference in the "major" carriers' rates. It often boils down to other factors, like line clearity, instant credit for mis-dials, quality of operator services, and tactics the carriers use to get your business. Hope this helps.

When I was in Germany last year, a co-worker of mine had a tone generator which he used to talk to his voice mail system, since his phone was an old analog phone. I noticed that it had not only the 0-9 and * and #, but also the A-D. I asked what they were used for, and I found out several uses. Apparently, the military (US only? Various other countries as well?) uses these for various communications protocols. One use I do know of is for a feature called AMIS-analog, a (CCITT?) standard protocol for signaling between multiple voice mail vendors. I don't know much about it, but it apparently allows for different voice mail systems to be able to transmit and deliver voice messages to appear as if they are part of one network, or something like that.

I remember seeing in some phreak information file once some instructions on shifting the tones in a normal touch tone dialer in some way by tying one of the IC's pins to high or ground or something like that. I think it was a modification designed to let one produce the ABCD tones. It described putting a switch on the side of the unit to switch between the normal and altered frequencies on one row of the touch tones. If memory serves, it said that the standard IC used for producing touch tones can make those extra tones, but that feature's usually not enabled in the U.S. I know this isn't much help, but your message reminded me of reading that, and if you have a need for producing those ABCD tones, perhaps someone here more knowledgable on the subject will know what I'm talking about and how to do it!

I hate to drag out what was a fairly innocuous question to begin with, but I'm not sure I'm following this. I guess you could have problems with residual sulfur reacting with air, but it seems like you'd need some consistently outrageous humidity to do it. I'd be wary of using denatured alcohol to clean up after emery cloth or steel wool, since it wouldn't dissolve the debris, but could carry it into undesirable areas before the alcohol evaporated. > ...a little conductive grease to exclude air at the point of contact > might be in order; this stuff can be found at any reasonable electronic > parts store.

The VIKING DLE-200A is a two-way ringdown circuit, which provides battery (32 V), dial tone, ringing (20 Hz - two seconds on, four seconds off) and CPC (150 ms). For about $110 each. When either side goes off hook, dial tone is presented for two seconds and then ringing goes to the other side. There are options to: - change ringing cadence (four versions) - eliminate CPC - issue five rings only - allow one-way operation only - eliminate dial tone and ring instantly. I am thinking of using this box to light up a dry pair for use with standard modems that don't support leased lines.

When the calling party hangs up on a conventional telephone circuit, the CO might give a CPC pulse, but it still keeps 48 vdc there to detect hookswitch status. It is up to the called party to go on-hook. With a voice card, this may require time-out or the ability to go on-hook after so many seconds of silence. You can use the Proctor 46220 (single circuit) or 46240 (four circuit) Ringdown Circuits. Information can be mailed to you after contacting Proctor at any of the addresses (including email) in the signature below. These ringdown circuits provide conventional CO-type 48 volt battery feed and 20 Hz ringing in each direction, so you can hook anything to it that you would hook to a normal phone line, except that there is no dialing required. There is a way around the problem mentioned above if you need to force an on-hook at the far (voice card) end when the user goes on-hook. Assuming that the service will always be one-way, if you REALLY want the ringdown to "drop the loop and DISCONNECT from the voice card" you can wire in a line sense relay that only connects the voice card end to the loop after the calling end goes off-hook. When the caller goes back on-hook, the relay opens again and the voice card is disconnected from the line. These loop detector relays are available from The Creative Aspect, 2345 7th St, Denver, CO 80211, and their fax/voice number is 303-433-7007.

Pushing the little button allows ringing current to reach the talking pair and the card which goes off hook when it senses the ringing. When it goes off hook and the phone I use is also off hook then the loop is completed and I use the touch tone buttons on my phone to manipulate the card (and what it does in the computer) just as though I had called from a regular line.

Not to be picky, but this is not true in all systems. The periodic updates only occur in switches which are programmed to provide (and capable of) something called "Autonomous Registration". These are updates which the cellphone sends to the switch to let the swtich know where the cellphone is. (An aside: does the switch tell the phone "Update yourself to me every 10 minutes" and the phone sends out an overhead from then on, or does the switch have to interrogate the phone every time it wants a location update? IE, do cellphones have a built in timer for Autonomously Registering systems? I've never got a firm answer on this ...) Thus, almost all Ericssons and AT&T Autoplex II (and I?) switches do this; some Motorolas do this. (Motorolas "click" when you dial out, and may click while it locates the mobile as well.) So the "B" side Motorola-based carriers in CA do this (haven't checked lately, maybe wrong), the "A" side carrier in CT, RI, and Western Mass does this, while in Delaware, Philly, Atlantic City and Boston, the Motorola based A-carriers do not. It really depends on the software and how updated your swtich is. Generally, as you expand outwardly and connect your system to others, it makes sense to go to Autonmous Registration. Otherwise, in order to locate a mobile unit, you will have to page your own system, and ALL other non-auton systems you are connected to, which can cause a LOT of congestion on the paging channel and the data/control links between switches/systems. This can cause "lost" pages (calls) and cause features link three-way or call forwarding to be slow or unavailable during congested periods. Cell One/NY dumped Motorola and went to Ericsson because, among other things, they needed to expand their connectivity for the then-planned NACN, and Motorola wasn't ready with their own system at the time. With a system like NY's, overload of the paging channels and control channels was a serious problem -- quite frequently callers got a re-order or "please redial" message because there was too much congestion on the paging channel, and not due to local channel (over)use at the desired mobile's cell tower. But if you are smaller system, and not part of a larger, Autonomous- based network, you may not need Autonomous Registration. For example, Cell One/VT, the Motorola-based "A" side carrier serving most of VT and Western New Hampshire does not use Autonomous Registration, as it is a small (customer wise) system, and not connected to anyone else. They may need to go Auton Regs if they eventually connect with Metro Mobile to the south in Mass, but right now it is unecessary. (Antother aside: Is Boston autonomous yet? I have always assumed it was not, but never bothered to check recently ... hmmm ... it would be interesting if it is NOT: It is connected to Metro Mobile/RI which IS autonomous. If that is the case, I guess Motorola EMXs can "talk" to both Autonomous and non-autonomous swtiches ... sort of like being "upwardly compatible"). So technically, not all (or even most) systems "know" where you are at all times. You can be in Vermont, and have your phone on, and assuming good coverage, leave it on all day and drive around, and as long as you don't place or receive any calls, no one will know where you are unless they specifically interrogate your phone. (If you drop coverage and then come back in service you may be interrogated again, I dunno ... different systems handle this differently, regardless of autonomous registration). So unless some tech in the switchroom is curious as to what YOU are doing, in non-autonomous systems, your whereabouts are not always known if you simply leave your phone powered up. > Whenever you have that phone powered up, and in communications with a > cell, that cell knows that you are there, and the management system > for all of the cells knows that you are there.

Powering up is not the same as autonomous registration. If the subscriber leaves the mobile unit on, even though an overhead was sent upon power-up, it will not continue to be sent at given time intervals, unless the switch also supports autonomous registration or some hybrid mechanism of such. This is why I noted up there about loosing coverage -- I am wondering which swtiches consider that to be the same as a power up, or if the phone will send out an overhead upon regaining a good signal, etc ... > if you drive from home to work with it on, there can easily be a log > made of when you cross from cell to cell. Ummm ... in a system with a few towers (or one tower, like those set up along Interstates to get roamer $$$) there may be too few points to get a good pattern (although you could probably tell whaat direction they are going by what sectors of the tower are being used, and estimate speed as well). In large, overcrowded systems, you may get serviced by MANY different towers, depending on traffic and weather conditions. For example, in New York, if you place a call from a 20+ story building, you can get serviced by a nearby tower on Manhattan Island, a tower in New Jersey, a tower in Queens, or a multitude of towers along the Brooklyn "waterfront". So it would be hard to get an fixed pattern. You could, of course, get a rough pattern, ie, "Active in New Jersey around 8AM, drops at 8:30 AM while in Holland Tunnel, active in Manhattan at 9AM (tunnel traffic! :) ), active for eight hours in Manhattan, then drops, and then active in New Jersey at 5:45PM. But as to specific routes, it gets hard, and is in some instances totally impossible.

True indeed! My old 83 channel UHF TV can readily provide testimony that most cellular users are completely oblivious to the fact that their conversations are "broadcast" all over town. Curiously, some of those alleged conversations that appear on my TV seem to be simplex type channels where both parties can be heard simultaneously. At first, I thought it might be sidetone from a cheap instrument, but it seems to happen quite frequently. A dissection of my cell phone shows that it has a diplexer, but it doesn't look like a directional coupler, so I'd think that a simplex link wouldn't work.

It needs to of course do telephone answering, but additional I installed such a voice mail system (PC based, eight lines) at a NY amusement park last summer. After a bit of research I bought the voice mail/auto attendant hardware and software from a company in Hawaii called Provox. They sell their software bundled with Dialogic voice boards. Their software comes with a menu driven system and a small programming language for setting up menus and doing various voice mail and attendant type tasks. I think you can do your paging via this small programming language. The system is quite reliable. The programming language docs have a few errors but after you get over this, it works well. You must be quasi computer and telecom literate to get it up and running. This is definately not "plug-n-play", however their tech support is quite helpful and patient. You need a 386 with four megs of memory and about 60k of hard disk space to run this system. I dont have the 800 number handy, but 800-555-1212 should be able to get it for you.

It is mostly distance based. Each prefix has a set of prefixes which are local from it (out here, one prefix away is local, further away is toll). There is a BBS in Long Beach which gives free memberships to anyone donating a phone number. People who have a second line used for dialing out give the phone number to the BBS by setting up call forwarding on the out-dial line to a number as specified by the BBS. They can then continue to use the line for out-dialing. By chaining these numbers together, the BBS gets numbers in a variety of prefixes, thus offering local calling to a wide area. The number I use to call this BBS forwards three times, each hop is local, but the end-to-end call would be a high (intra-LATA) toll for me. It does take several seconds to set up the call, though.

If the only problem is the switching of using inside/outside pair, it's pretty simple -- in the U.S., the outside pair is used for a second line on a two-line jack. Various manufacturers sell a little jack that allows you to plug into a two-line jack and run separate single-line phones on the two lines.

I will never understand why what is essentially a Personal Identification Number (PIN) is printed right on your phone card. It's like putting your bank PIN right on your ATM card. Secondly, I had a question about how local phone company cards are supposed to work around the country. I have a Pacific Bell calling card, and while traveling last week I couldn't find a phone that would accept the card by simply using the mag stripe reader. The phones, owned by AT&T and Illinois Bell, would tell me that the card was not valid, but worked fine if I manually punched in the digits. Am I wrong in assuming that the stripe reader should have worked? It seemed to defeat the whole purpose of the only possibly secure way of using the card.

How about an adaptation of the SecurID cards (the ones that basically have you do a challenge/response with the other end)?

Those words are someone else's that I probably quoted in my article. IMO, it is dangerous from a perspective of fraud control to have more than one person billing to the same account, with no way to differentiate between them. Not only does it increase the odds of someone obtaining your card number (two cards, two times as likely), it also makes the detection of the fraud by either party more difficult. Using unique card numbers would also ease the problem of sorting out whose call is whose at the end of the billing period, much like Call Manager from AT&T does with LD service.

You didn't mention what the data rate is, so I'm assuming it's low. If 300 baud will do, then you can produce your own carrier to fool the modem with a simple tone generator. The frequencies are 1270Hz for an answer tone or 2225Hz for the originate tone. For 1200 baud this should also work; the frequencies are 2400Hz for answer mode and 1200Hz for originate. For 2400 or above I think you would need something more complex than a single tone. Allan N.

Reply-To: Jim.Rees@umich.edu Organization: University of Michigan IFS Project Date: Thu, 6 Aug 1992 19:06:50 GMT Didn't AUTOVON use the ABCD keys for call priorities? The standard old Western Electric DTMF pad had an extra tap on the "columns" inductor for the ABCD keys. I think there were even some traces on the PC board, but of course the switches weren't there. The Audio Response Unit (ARU) on the University of Michigan's IBM mainframe (running MTS) had a decoder for a third dimension of DTMF keys, so you could send it tone triads, for 64 possible "keys." I never knew anyone who used this feature. I've got the frequencies somewhere. They were not engineered for minimum talk-off, as the row and column tones were, they were just round numbers like 1550, 1650, 1750. Does anyone remember the original WE 10-key pad? I had some of these that I converted to 12-key by drilling a hole in the face and adding a couple of chunks of plastic for the '*' and '#' buttons. ------------------------------ End of TELECOM Digest V12 #609 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa01321; 7 Aug 92 4:27 EDT Received: by delta.eecs.nwu.edu id AA17978 (5.65c/IDA-1.4.4 for telecomlist-outbound); Fri, 7 Aug 1992 02:27:08 -0500 Received: by delta.eecs.nwu.edu id AA19361 (5.65c/IDA-1.4.4 for telecomlist); Fri, 7 Aug 1992 02:26:59 -0500 Date: Fri, 7 Aug 1992 02:26:59 -0500 From: TELECOM Moderator Message-Id: <199208070726.AA19361@delta.eecs.nwu.edu> To: "\\telecom"@eecs.nwu.edu Subject: TELECOM Digest V12 #611 TELECOM Digest Fri, 7 Aug 92 02:27:00 CDT Volume 12 : Issue 611 Index To This Issue: Moderator: Patrick A.

There was TV news coverage of this last weekend (Aug. 1 and 2) and I note the following item from the {St. Louis Post-Dispatch} August 5, 1992: PHONE-CABLE THEFTS HERE DISRUPT SERVICE TO 5,000 If your telephone doesn't work, it may be because someone is going out at night with a hacksaw and cutting 150-foot sections of cable from the telephone poles in your neighbor's back yard. Last weekend, there were nine such nighttime thefts in the vicinity of St. Louis Regional Hospital and the Walnut Park neighborhood. It was the first time that telephone cable thieves had struck in St. Louis. They apparently intend to strip the insulation from the cable and sell the copper wire for salvage. "This happens about twice a year in Missouri, mainly in rural areas," David Freiberger, general security manager for Southwestern Bell Telephone Co., said Tuesday. "It's amazing that they will go to this much effort," he added, because each stolen section of cable is worth only between $15 and $180. And there is another danger: the telephone cable is strung on the same poles as electrical cable. Anyone who cuts the wrong cable risks electrocution. Repairing each cut costs the phone company about $15,000. About 5,000 customers were without phone service for as long as 12 hours last weeekend. To discourage this activity, the phone company plans to announce today a $1,000 reward for information leading to the arrest and indictment of the cable thieves. Several witnesses saw the thieves but haven't been able to identify anyone yet, the phone company says. *** End of article *** To add some info based on the TV news coverage: An example of the cut cable was shown -- it appeared to be about 100-pair or so. The telco spokesman asked that anybody seeing what appeared to be telephone repair people who were working with hacksaws or chainsaws to call this in immediately (but how would they be able to if it was their own cable being cut? :-); that this was not how real telephone repairers worked. Also, neither in the above nor in the TV news did anyone ask or address one possible solution and prevention of this situation -- replacing copper with fiber. I'm surprised the telco doesn't take the opportunity to replace the aerial cable with fiber in these areas where the cable was stolen. (Or would that cost a vast amount more, requiring some sort of powered fiber-to-copper converters at every line drop? Just how does a telco handle the transition from fiber strung between the poles to copper pairs going into a house? What happens to telco-line-powered devices in this circumstance? How is ring current generated? Are there separate fiber-to-copper convrters for every drop, or still a copper multi-pair cable for the neighborhood with one central fiber-to-copper unit up a pole somewhere, with its own electric meter and hooked to electric lines, mainline fiber, and neighborhood copper distribution? Does having fiber-to-copper, or even fiber to the home, mean that your phone service dies when electric power dies? Or is the fiber paralleled with current-carrying wires to provide CO battery to the drops?)

Reply-To: wex@cs.ulowell.edu Organization: Univ. of Lowell CS Dept. Date: Thu, 6 Aug 1992 13:07:00 GMT Hi, I'm posting this for a former netter who has recently moved from civilization to a farm :-> (Mass to VA (USA)) /Bernie\ has email access but no news feed (as yet), so please reply to him as bpc!bernie@bbn.com, or post, as usual and I'll forward replies. Anyhow, he has an interesting problem: He wants the same phone number to appear in three buildings on the farm that are quite a distance apart, and C&P seems not to be willing/able to do this for him. (That's another story.) He can get them to drop the line at any of the three buildings, and he is willing to run wires to the others the question is to which build- ing should he have the feed run? The following is his description: You might recall that I had been sort of arguing with C&P Telephone about getting the same number installed in the two houses on the farm. Well, I've at last gotten the story on why they claim they can't do it: their assertion is that it is the fault of the computer system they're using. They claim that it *cannot* handle having a number ring at two different service points. Sounds a little bogus to me, but I've gotten this story consistently enough from enough different telcofolk that I suspect that it is at least unfinessable, even if not completely true. [on the other hand, it is actually possible that the phone company could distribute software with so simple a bogosity?] Anyhow, what he recommended is that I just run wire between the two houses and connect up the service myself. It is a little over a quarter mile between the two houses, so I'll be poking around to find someplace where I can get suitable outdoor-OK cable in long-enough lengths [amusingly, the last guy I spoke to said that it shouildn't be hard to find what I need, but if I do get stuck I should call him back and he'd see if he could make some arrangement for me to get the cable from telco]. Minor technical question: the situation is that I have three buildings that I'll be wiring to the same phone service. The one in the middle really is about in the middle, about 1/8 mile from each end. Now, the actual phone service comes in: --> A -----------------------> B C [we have phone service to A and B [although they are not on the same line yet], and the poles go right past building C, which is just being built. The question is: does it make any difference in terms of signal quality or voltage limits or the like for where I get the 'real' service installed and which way I run the "extension" drops. Right now, the 'real' number rings up at B, and so the most natural thing to do is to run the extension line back down the poles toward A, putting in a drop at C as I go by: -------------------------------> B | / A <---------- C <-------------- But it really pains me to see that wiring go *right* past A, a quarter mail past, and then ahve to doouble back the quarter mile. One thing I could do is ask the phone company to _move_ the primary service from B to A, and then just run the extension up the line. The third alternative is to have the telco service be installed at C, and then run drops in both directions [each only 1/8 mile now] to A and B. Will any of these make any difference? ----- end of Bernie's description ---- Thanks. [Moderator's Note: Someone at telco is just plain stupid. If what they said about 'the computer can't handle it' was true, then no one could ever have an extension phone. There is no reason on God's green earth that *they* (telco) cannot handle the whole thing. I wonder if they ever heard of jumpers between pairs? I wonder if I went to their CO and looked around if I would find jumpers all over the place as is common in every other CO in the world? If you can attach some wires in parallel at your end so that two instruments in different buildings can ring at the same time, then they can just as easily attach two or three pairs in parallel at their end to do the same thing. When I moved from one place to another about two miles apart several years ago I was within the same CO so I got to keep the same number. I had Illinois Bell turn it on at the new location for several days before the old place was turned off as a way to ease our transition in moving. What one of the Bell sisters do, the others can almost invariably do also. Ask telco if they have any answering services in town that are bridged to their (the answering service) customer's lines so the phone rings at the service at the same time as at the subscriber's premises. I'll bet they do. And if so, how do they deal with that?

NAP permits the A Series line of general purpose computers to interface with a switch. This means the power and flexibility of these systems can be used to develop telephony applications. UNISYS NEWS NETWORK, AUGUST 6, 1992 SHENZHEN POSTS AND TELECOMMUNICATIONS BUREAU OF CHINA PLACES $5 MILLION NETWORK APPLICATIONS PLATFORM ORDER Unisys has received a $5 million order from the Shenzhen Posts and Telecommunications Bureau (SZPTB) in the People's Republic of China for a Network Applications Platform 16 (NAP16). The City of Shenzhen is a special economic zone across the border from Hong Kong in China's southern Guangdong province. The Unisys NAP16 system will be used to develop an integrated value-added information network to provide a range of extensive and comprehensive information network services in Shenzhen. The initial planned service offerings include "phoneless communications," voice mail, electronic mail, facsimile mail, information provisioning and IDD calling card services. Other services are expected to be added, based on future requirements. Based on Unisys A Series mainframes and utilizing specialized network interface and voice interface modules, NAP provides the industry's first full- featured environment for both voice messaging and Advanced Intelligent Network (AIN) applications. "The City of Shenzhen will be the site of the first mass-market installation of voice mail in Asia," said Ed Blechschmidt, president, Unisys Pacific Asia Americas Division. "Phoneless communications is a system that assigns a telephone number to an individual who does not have his own telephone. This is designed to overcome China's critical requirements on communication. The NAP16 will allow someone to call a number and receive instructions to either leave a message or to perform other actions. The caller can contact the central message center from anywhere -- in China or out of the country -- to receive the message and respond," said Blechschmidt. "With the assistance and cooperation from the city and provincial governments, the SZPTB has been able to make significant progress in the provisioning of telephone services. This year the number of telephone lines for Shenzhen is expected to reach 450,000 ...," according to Xu Li Yong, director, Shenzhen Posts and Telecommuni- cations Bureau. The number of lines is expected to increase by 250,000 lines per year, reaching 1.2 million by 1995. --------- Randy Gellens randy%mpa15ab@trenga.tredydev.unisys.com >>>>>>> If mail bounces, forward to rgellens@mcimail.com <<<<<<<< Opinions are personal; facts are suspect; I speak only for myself ------------------------------ From: kovar@world.std.com (David C Kovar) Subject: MCI Account Illegally Created in My Name: How to Handle This? Organization: The World Public Access UNIX, Brookline, MA Date: Thu, 6 Aug 1992 14:42:42 GMT Approximatly three weeks ago I received a letter from MCI thanking me for signing up for a calling card with MCI. I dislike MCI and never would have signed up for a calling card, so I tossed it away. I received a second letter stating essentially the same thing a few days later. Figuring something was wrong, I called MCI, explained about the letters and explained that I did not sign up for a calling card. They told me that an account had been opened in my name the previous month but had been closed. This was a bit disturbing, but they assured me the account was closed, so I let it go. Two days later an MCI calling card showed up in the mail. I called again, explaining everything. "Yes, it was open, but now it's closed." Then why did I have a new card? They couldn't explain it. The next week, I received a bill from $320 from MCI, all calling card calls, all for a three week period starting in early July and extending through the period that I'd been calling MCI about the problem. 90% of the calls were to 617 numbers that are local to me. I calmly hit the roof. After wading through various reps, I finally talked to someone who told me to send in the bill with a letter and they would investigate, clean up the bill, and let me know who opened up the account and how. In my letter I gave them my work number and explicitly stated that I wanted to know who opened the charges and how they did it. Since then, I received one call from a rep at 8:30 on Saturday morning thanking me for signing up with MCI. I received two calls asking when I was going to pay the bill. And no calls about my letter. I called them today. Essentially, the account is closed, the bill negated, and that's it. They didn't figure out who did it and the rep said it would be "very difficult to figure it out." I tried explaining things to her and got nowhere. I tried asking who investigated such things within MCI. They said that noone did. They said they couldn't call the numbers on the bill in an effort to determine who called them. I would like to know: a) Who can I talk to at MCI who has a clue about this stuff? The reps I've talked to keep toeing the party line and can't or will not give me any information. "Yes, we're sorry, yes, the account is closed, no, we can't tell you any more. Please go away." b) If MCI can't help me, can I go call the numbers on the bill in an effort to figure it out on my own? If so, what's the best procedure? c) Would any newspaper care about this sort of abuse and insensitivity to the abuse? It really pissed me off that someone used me to defraud someone else and MCI will not help, or even call me back to talk to me about it. d) Any clue on what happened? My guess is that someone opened up an account in my name and then called into say the card was lost and somehow got the new card number over the phone. One rep said that the card had been lost and reissued. I only received one card, presumably the second one. Where did the first one go? How did the person get the new calling card number? Any information and thoughts on this would be most welcome. David [Moderator's Note: MCI won't tell you who did it because they probably don't know who did it. And yes, I would definitly call the phone numbers shown on the bill and try to learn the truth from them. Get the name and addresses for the numbers shown on the bill and check for similarities, etc. You might find out something interesting. Some of the phreaks who pull this stuff are actually stupid enough to call their family, employer, etc using the fraud account. PAT] ------------------------------ Date: Wed, 5 Aug 1992 05:09:48 -0400 From: Monty Solomon Subject: 900 Number Calls to HOT DATES From the 8/4/92 {Wall Street Journal}. Heaven help the Harmarville United Presbyterian Church. When George B. Powers, the clerk of the session, opened the church's phone bill, he saw that the usual monthly amount -- about $18 -- had ballooned to almost $80. Not only that, most of the toll calls were to a 900 number for HOT DATES. "It must be some sort of a call-in phone, where you can get into some exotic conversations," he says. But with a congregation numbering 20, many of them elderly, no culprits came to mind. "Our youngest member is a grandfather and he's 55 or 56," says Mr. Powers, 79 years old. "None of us would be calling HOT DATES." The elder trustees searched the 134-year-old church and discovered a cut window screen, which police advised members not to repair. The trap was set. The phone bill showed calls to the sex talk line on June 30 and July 17. "I was expecting him to come back," says Patrolman Reilly Perrett, who patrols Harmar Township. "So we put extra patrols out in that area." On July 24, at about 10 p.m., Officer Perrett noticed a car parked at the church, which is on a dead-end street. Then someone opened the church door and stepped outside. The policeman immediately arrested the suspect, David DeBaker, 27, who now sits in Allegheny County Jail charged with burglary, theft (for the phone calls) as well as receiving stolen property (police said the car that Mr. DeBaker drove to the church and its license plates were stolen). Mr. Powers has since notified the telephone company, which agreed to adjust the bill to $22; it may make allowances again if more calls to HOT DATES are on the next statement. Nancy Clausen, of the National Coalition Against Pornography in Cincinnati, says federal regulations now in effect should begin to discourage such offenses. A subscriber is supposed to request access in writing and arrange prepayment for sexually oriented 900 lines. Meanwhile, the parishioners are in the process of selling the church, so they haven't had time to consider measures to prevent a repeat of the incident. "Our only precautions are to notify the police," says Mr. Powers, "and just keep and eye on the telephone bills." Amen. ------------------------------ End of TELECOM Digest V12 #611 ******************************   Received: from [129.105.5.103] by mintaka.lcs.mit.edu id aa01462; 7 Aug 92 4:30 EDT Received: by delta.eecs.nwu.edu id AA12099 (5.65c/IDA-1.4.4 for telecomlist-outbound); Fri, 7 Aug 1992 01:35:29 -0500 Received: by delta.eecs.nwu.edu id AA21755 (5.65c/IDA-1.4.4 for telecomlist); Fri, 7 Aug 1992 01:35:19 -0500 Date: Fri, 7 Aug 1992 01:35:19 -0500 From: TELECOM Moderator Message-Id: <199208070635.AA21755@delta.eecs.nwu.edu> To: "\\telecom"@eecs.nwu.edu Subject: TELECOM Digest V12 #610 TELECOM Digest Fri, 7 Aug 92 01:35:19 CDT Volume 12 : Issue 610 Index To This Issue: Moderator: Patrick A.

I am sorry, but I dont see how these statements (even in their entirity) constitute a rejection of science. If anything they constitute a recognition of the changes which come about when exponential increases of usership create situations never envisioned when Usenet was created. Usenet's technology is based upon trust and a general (alleged) respect and maturity between users. Like Ham radio, Usenet had a level 'a cut above' the average local bbs or CB radio channel. The primary users were university students and corporations within the general field of technology. Now-adays, there are public access sites where, for a few dollars a year, virtually anyone can (and does) gain equal access to this giant network. Obviously, when such floodgates are opened, some carp will get in along with the rainbow trout :-). I am not saying that public access is bad, per-se, but it surely does change the face of the medium. I use public access sites, myself, and am grateful for their existance. However, like the analogy of Ham radio and CB, the increasing size and ease of entry, WITHOUT substantial changes to the workings of a network which was never designed to handle such traffic, does present a problem. In Ham radio, one must pass tests of technical competency, and learn a binary code (Morse) to enter the airwaves as a legit Ham. This compared with walking into a Radio Shack or a flea market and plunking down a few sheckles for a tranceiver. The requirements involved in obtaining a Ham license, are a means of drawing a line between those who are serious about global communications, and those who want to merely broadcast their ego's around their neighborhoods. On Usenet, one needs only to posess a terminal and modem and they are instantly involved with global communications. > If one looks at the world this way, then one would always long for > "the good old days" when only the qualified and intelligent would be > able to use a service. I have no problem with requiring SOME minimal level of competence and intelligence when piloting a global system of communication like Usenet. There are thousands of local BBS's, where one can log-in and be as un-intelligent and non-qualified as one wants. We don't give drivers licenses to every kid who rides a bicycle. > You must understand that you were pioneering USENET/email/packet > transfer of data in the seventies.

I don't think it is a 'backwards or forewards' argument. It is more an argument of increasing the size of a network, without considering the ramifications of that increase. Like Ham radio, which is also international, one can easily ruin, or damage, the viability of such an exchange medium, if one jumps in 'willy-nilly' and starts bellowing without regard for it's effects.

Cb'ers live in smaller arenas and can, therefore, play their silly games without too much real degradation of areas beyond. Usenet (like Ham radio) is international, and therefore has much greater impact on our world. As the uninitiated join our ranks, without respect for the traditions and conventions of the network, the law of CB (talk loud, listen little and pay no attention to the feelings/opinions/rights of others) is becomming more and more the rule. BTW CB WAS indeed originated as a serious 'business' communications band, but that's another newsgroup :-). > While netiquette is less and less observed, isn't the situation > similar in any country around the world? > Usenet brings debating between people of very different background > and origin possible.

Usenet is operated primarily through the courtesy of institutions of learning, the military and major corporations. Most traffic is handled on a big "you scratch my back, I'll scratch yours' basis. Most of the 'expense' is not borne by the average user, but by the afore-mentioned orginizations. If the users had to pay the frieght for all the connections and long-distance lines, I dare say (s)he would be less frivolous with the flames and such. Usenet is also propagated via hobbiest UNIX enthusiasts, who bear the brunt of most local connections. Much of this is invisible to the 'newbie' user who merely has to press a few keys and 'magically' their message is propagated worldwide for the price of a local phone call. > In short, I tend to believe that it is unlikely that sites would pull > the plug on Usenet. If they did, then it would be the consequence of > ERM ... elderly system managers (apologies to Pat et al) Many sites have already pulled the plug on alt.* groups, because of space limitations and because many are mere jokes. Still other sites have gone further and eliminated talk.* and even rec.* groups due too the increase in the noise and the seemingly uncontrolled proliferation of newsgroups dedicated to ever narrowing and esoteric interests. It is incorrect to assume that there is a bottomless pit for this traffic. As more 'backbone' sites refuse the periferal groups, the smaller sites 'below' them also lose the feed. All it would take is for AT&T, Motorola, the military sites, and a few key Universities, to clamp down on the costs of this network, and we would see a lot of downstream sites dry up real quick.

PAT] > know ourselves how much information we can chew-up every day? Perhaps > our minds will train themselves into going through so much data. I think something important is being forgotten here. Usenet is very different from radio in a very important aspect -- you can filter what information you receive, without using many brain cells at all. Just give your favorite news-processor good kill information, and let it ignore for you all the things that you aren't interested in. Everyone who reads news does this, as they cannot possibly keep up with the raw data flow (40M / day, or so, isn't it - a mere 77 words / second).

This brings up a related question: is there any time period, determined either by tariff or convention, for a long distance carrier or AOS to bill a customer? Some time ago I unknowingly made calls from a pay phone connected to one of the high priced AOS's. The charges showed up on my bill several months later and it took me a few minutes to recall that I did, indeed, make those calls. If the charges had come six months or a year or two years later, I would have been hard pressed to remember. Would I still be obligated to pay after an inordinate amount of time between incurring charges and receiving the bill? How long is "inordinate" if the answer to the previous question is "no"? Common sense tells me there must be some limit to how long a bill can be delayed. Any thoughts? Dennis R.

Seems like we might be overlooking something here; if you are interested in privacy, you probably shouldn't be using a cellular phone in the first place! Anybody with a scanner that covers the 800MHz range can (illegally) monitor cellular calls. This is true even for scanners that have the cellular frequencies locked out; since the selectivity is (usually) relatively poor, scanner users can often listen to the deleted cellular frequencies at the desired frequency plus the I/F frequency of the scanner.

Ericsson Toshiba Telecommunication Systems K.K. will be established on September 1, 1992 and headquartered in Yokohama. Initially capitalized at 200 million yen (approximately USD 1.57 million), the new company is owned 60 percent by Ericsson and 40 percent by Toshiba. The company expects sales of 32 billion yen (approximately USD 252 million) in 1994. Ericsson Toshiba Telecommunication Systems will design, supply, install, maintain and service digital mobile telecommunications systems for Digital Phone group of Japan, a group of cellular mobile telephone service companies that will start operation in 1994. The new company will serve to link the partners to the Digital Phone group. In Japan, the 1.5 GHz frequency band was allocated to digital cellular mobile communications in 1991, and two new digital cellular mobile telephone service companies that will offer nationwide communication networks were established. One of them, Digital Phone group, will construct nationwide stations by around the year 2000, under the management of regional operating companies. Three regional companies, Tokyo Digital Phone K.K. (Tokyo area), Kansai Digital Phone K.K. (Osaka area) and Tokai Digital Phone K.K. (central Japan area) have already been established, and are preparing to start services in 1994. Ericsson Radio Systems is scheduled to ship digital cellular mobile telecommunication base stations and exchange systems to Tokyo Digital Phone and Kansai Digital Phone. After its establishment, Ericsson Toshiba Telecommunication Systems will act as a representative organization for Toshiba and Ericsson in this equipment supply business. The alliance between Ericsson and Toshiba will enhance telecommunication technologies in Japan and assist Ericsson's entrance into the Japanese market. Ericsson is an international leader in telecommunications, recognized for its advanced systems and products for wired and mobile communications in public and private networks. Ericsson has 70,000 employees and activities in 100 countries. Ericsson Radio Systems has earned a top ranking in mobile telecommunication infrastructures; the company has a 40 percent share of the world market for cellular mobile telephone systems, with systems for all standardized cellular systems in the world, including the three new digital standards, GSM, American Digital Cellular and Japanese Digital Cellular. Ericsson has a joint venture company with General Electric in the USA, Ericsson GE Mobile Communications Inc., which actively conducts mobile communication business. The collaboration between Toshiba, a world leader in semiconductor, information and communication business fields, and Ericsson, a world leader in the telecommunications business, will expand the scope of further development of advanced technologies and business in the telecommunications field.

There have been several recent posts recently about various billing problems with the LEC. I will share two that may be different enough to help others find those elusive overcharges. 1. We have about 20 lines coming into our office; about eight incoming only customer lines to a PBX with ACD, about six incoming/outgoing business office line, and several miscellaneous dedicated lines. About a year ago we overflowed our office and one employee set up office at home. We divorced one line (business cards etc. were already in circulation) from the business office rotary and had it installed in the employees home. Last month we noticed a few random calls from MCI on our PacBell bill. Our LD carrier is Sprint; billed separately. We checked all in house lines with 1-700-555-4141; all Sprint. (We uncovered one that had NO assigned carrier. The result: we could make no long distance calls on that line, either dial 1 or 10xxx access code. Apparently fairly common with business lines which are not automatically assigned a carrier like residence lines . It had never been noticed because it is an incoming only line in typical use.) After the usual time consuming run around between carriers, PacBell identified some of the numbers for us. They were coming from the employee's home line which had to been slammed to MCI since it moved as Sprint. Problem solved, well sort of. Seems that we had been billed for the line both separately at the new "residence" location and continued as part of the 15 line billing at work. The PacBell rep noticed it as we dissected the long distance problem and they are working on the year's refund. 2. All this discussion and reading the Digest suddenly reminded me that almost exactly the same thing had occurred in the early 70's with a very similar moved line. That refund was for about three years. If that has happened twice to me, whose job is not following phone bills or telecom stuff directly, it may fairly common. Moral of the story: get a detail summary of all bulk bills at least yearly and have some one/s who can verify that you get what you are paying for. We are also still researching the $13.80/month charge for a "remote trunk busy arrangement". The phone company knows that is what we are being billed for it, but can't, at the moment, tell us where it is in the CO , nor where it terminates on customer premises, nor what line/s it busies. ------------------------------ Subject: Information Age course at Georgetown From: stapleton@misvax.mis.arizona.edu (Dr. Ross Alan Stapleton) Date: 6 Aug 1992 15:35 MST Organization: University of Arizona MIS Department For those in the greater Washington DC area, I will be teaching a course in Georgetown University's continuing education program, surveying issues arising from our entry into the "Information Age." The course description is below, and it runs for eight Thursday evenings.

What does it mean to say that "information about money is as valuable as money itself?" Many companies do nothing more than broker information, as an increasingly larger percentage of the U.S. economy. But where ought the boundary between commercial profit and personal privacy be drawn? Lotus Development Corp. cancelled its plans to market a database on consumers in the face of protests from those it would have monitored, and across the U.S. "caller ID" technology is facing severe scrutiny from all sides. In the wake of the failed Soviet coup, a U.S. communications company took out a full-page ad to congratulate Soviet citizens who, "armed with nothing more than information ... saved the day." News of the Tiananmen Square massacre came to us out of China by way of portable satellite dishes and the fax machine. Information systems are making life more efficient, but never before has it been possible for a simple computer glitch to cause a billion dollars worth of damage -- twice in 1991 software bugs crippled large portions of the U.S. telephone system, and a Cornell graduate student's program shut down tens of thousands of networked computers in 1988. The legal profession is scrambling to apply yesterday's laws to new realities, and "artificial reality" has been used in court testimony, while the FBI lobbies to make digital telephones easier to wiretap. What do we have to fear from "hackers?" Does computer crime pay? Readings will be provided, taken largely from the current press, to serve as background and focus for discussion. Dr. Ross Alan Stapleton is a science and technology analyst with extensive experience studying computer and information technologies in the former USSR and Eastern Europe. Eight sessions, Thursday evenings, 7:45 to 9:15 p.m., September 24 through November 12, 1992. ------------------------------ Date: Fri, 7 Aug 92 00:52:48 -0400 From: Doug Humphrey Subject: NYSE Processing A little background; NYSE processing is actually done by SIAC (Securities Industry Automation Corporation). SIAC does the transaction processing for both the NYSE and the AMEX (American Stock Exchange). Main SIAC processing is located at 55 Water Street, just a block or so from the NYSE trading floor. Recently, because of things like the power and communications outages that you have mentioned, a backup processing facility has been established at Metropark, and business park in Brooklyn. During the trading day, both facilities are "live" and do transaction processing. At any time, either site can come offline and not disrupt the processing at all. Both sites are sized to handle the total processing load. I will note here that all of the "critical" processing is done on systems built by Tandem Computers, the firm for whom I work, and these systems are "fault tolerant", meaning that they are able to sustain single points of hardware failure without effect on the applications that are running. The 55 Water Street site has in excess of 150 Tandem CPUs arranged in several "systems"; being a parallel processing architecture, these things do change from time to time, and you have to keep an eye on the configurations to be sure how many CPUs are in a given system. Metropark has the same level of processing power, but fewer actual CPUs because they are operating many functions on the new RISC based Cyclone processors; much faster than previous technologies. Almost without exception (and the exceptions are small), every stock exchange on the planet operates on Tandem systems. There are other manufacturers systems installed, but mainly you will find they are "back end" systems. For the critical "online transaction processing" function, you will find that even a few seconds of downtime has very scary impacts, secondary effects, etc. This is not an ad for Tandem, really. If you are discussing the dangers of depending on the "online society" then you should consider that this is the absolute bleeding edge. Last time that I saw uptime stats during the trading day, I believe that they were better than 99.99% for the year, and they included communications outages and operator errors in that number. ICBM launch systems don't do that well (though the numbers for them are classified).

Well guess what, someone must be listening. AT&T just announced a new program called TELETICKET. This program will sell "stored value cards" of 10, 25, or 50 units (current rate is $.60 per unit). These cards are geared to foreign travelers in the USA, and may be used to access the AT&T network or to use information services in one of nine languages. I called the TELETICKET people to get more details. These cards anre "stored value", but they are not "magnetic strip" cards. You purchase a card from TELETICKET (via check, money order, or charge card) and then use it via the TELTICKET interface (a USA 1-800 number) to make long distance calls (inter-lata or international via AT&T). It is essentially a limited value "calling card". You have to punch in your 10-digit TELETICKET card number, which is of course "printed on the card" (oh well). At least if someone steals your TELETICKET card or number the most you are out is $30, with a regular calling card I think your minimum liability is $50. I intend to order one of these and play with it. They are supposed to send me more information, but the customer service rep. said they were running short on info brochures. The cards are currently available only via the mail or from one POS office in San Francisco "on market street". I asked if more POS places were in the works, and the answer is yes -- maybe even phone centers, but demand will dictate how sales are handled. They anticipate that the primary users of these card will be foreign travelers and business folk. As far as rates go, I don't know yet -- my guess is it may be slightly higher than dial '1', but still competitive enough to make it more attractive than dumping rolls of quarters into the local IBT phone to call Turkey! If anyone is interested, I would suggest calling the English speaking TELETICKET customer service line at 1-800-462-1818. If I get more detailed information, like the full list of 800 numbers for the languages, - or a number that can be reached from outside the USA, I will post. (You might try asking for TELETICKET customer service from your in country USA DIRECT operator.) Since I am up to my eyeballs in inbound AFS foreign exchange students at O'Hare airport this week -- I thought this was a timely topic.

Bell The August 3 issue of {Telephony} has a little blurb about the 70th anniversary of the passing of Alexander Graham Bell. At 6:25 PM Eastern time on August 4, 1922 all telephone service in the USA and Canada was suspended for one full minute to mark the death of Bell two days earlier. The silence fell at the moment that Bell was laid to rest in his tomb. No mention was made of how they did this. Did all cordboard connections in all central offices get yanked at the same time? Can you imagine trying to pull this stunt today? The article goes on to say that seven years prior to his death, Bell said he looked forward to the day when people would communicate without spoken words using coils of wire about their heads to communicate thoughts by induction. Paul Cook 206-881-7000 Proctor & Associates MCI Mail 399-1080 15050 NE 36th St. fax: 206-885-3282 Redmond, WA 98052-5317 3991080@mcimail.com [Moderator's Note: During the last several years of his life, Alex Bell had completely avoided any day-to-day involvement with the Bell System and AT&T. He was not on very friendly terms with the management of the company in latter years, although he was still a very large stockholder in AT&T along with his wife Mabel and the royalties from the use of his invention kept him a wealthy man until he died. On the day he died early in August 1922, Mabel called the company and spoke with a couple people in senior management with whom Alex had remained friends, and told them of his passing. It was publicized in the media the next day that the Bell System would note the occassion with a nationwide minute of silence, and subscribers were asked to voluntarily refrain from using their telephones at the appointed time. A neighbor of mine for many years spent about forty years employed by 'The Telephone Company' until she retired in the late 1950's. She was with the Bell System at the time and to the best of her recollection hundreds of Bell System management employees attended the funeral. No calls were 'yanked down'. Beginning about five minutes before the minute of silence, operators advised callers that emergency calls only were being handled for the next several minutes. With no new calls being started and old calls disconnecting normally over the next five minutes, traffic was virtually zero when the minute of silence was going on during which time the operators did not respond to any calls and the other employees paused in their duties.

A Cordless Phone That Can Thwart Eavesdroppers To industrial spies and other snoops, the millions of cordless phones in use are goldmines of information. Conversations can be plucked out of the air by means of a police type scanner, and with increasing ease. The latest no-cord technologies offers clearer sound and longer ranges -- up to half a mile. That's because the new phones broadcast signals at 900 MHz, or 20 times the frequency of current models. Cincinnati Microwave, Inc. [the radar detector people] figures executives and consumers will pay a small premium for cordless privacy. The company has developed a phone, to be marketed in October by its Escort division for about $300, that thwarts eavesdroppers with "spread spectrum" technology, which is similar to the encryption method that the military uses in secure radios. The signals between the handset and base unit are digitized, making them unintelligible to humans, and the transmission randomly hops among various frequencies within the 900 MHz spectrum. To keep the cost down to the range of other 900 MHz models, Cincinnati Microwave has developed special microchips that keep the handset and base in sync.

I got back many replies of the "please send me any info you get" variety, but no answers. One nice guy at Bellcore did do some footwork for me, though, and found out that a woman he worked with had been on the committee, that they had completed an initial report, and that the standards-setting work had been passed on to ANSI. Well, I have more information, taken (of all places) from {Networking Management} magazine, July '92, pp. 38-44. Here's a quote of the two paragraphs discussing VMUIS: "The Information Industry Association has led two efforts to standardize the way people interact with voice-based systems. One of these, the Voice Messaging User Interface Forum, completed its specification more than two years ago. VMUIS was intended as a standard interface that would promote consistency among products to 'benefit users in several areas ... including faster learning, greater productivity, and greater satisfaction,' according to the specification document issued in April 1990. "The specification covers core activities only, not options or prompting scripts, and it is not intended to homogenize the industry. It calls for vendors to use * to cancel or back up, 0 to ask for help or an operator, and # to terminate or skip ahead. It further specifies a consistent way to handle Q and Z, which do not appear on Touchtone keypads. Acceptance of VMUIS is limited; some vendors ignore it, others adopt just the parts they like." So. That still leaves me wondering, what interface standard (if any) are the telco voicemail systems adhering to? I think there must be one, because both brands of voicemail equipment NETEL has had in the Back Bay use the same keystrokes for everything. They even use the same prompts! Once again, if anyone knows more detail I'd like to hear it. Please email to me; I'll post new info to the net.

Ketcham) Subject: Adapting Hayes for Tape Recording Digital Data Date: 8 Aug 92 06:23:40 GMT Reply-To: ketcham@u.washington.edu Organization: University of Washington, Seattle I'm trying to slap together a quick-n-dirty system for tape recording digital data, and I'd like to fly this idea by the modem gurus out there. The background story is we're doing some deep ocean research and we have this cruise coming up on pretty short notice. We want to take a stereo tape recorder out and record acoustical hydrophone data on one channel and digital Global Positioning System (GPS) data on the other. Then we take all this data back home and analyze it offline, to determine where things are located down there. The GPS data is serial ASCII and the interface is configured to plug into a modem. The problem is to get this data onto an audio tape. We have some cheap hayes compatible modems laying around (this is a real shoestring operation.) What I'd like to know: Is there some way I can go directly from modem to audio tape recorder? I've seen this sort of thing done with expensive high end modems and it seems like it should work in principle. While I have some experience writing software to talk through these modems, I don't really understand how the handshaking and signalling works on the wire side of the things. It seems to me that these hayes type modems look to see another modem on the other end of the line, and if they don't see one, they won't talk. So would it be too difficult to deceive the modem into thinking it's talking to another modem, or otherwise defeat this carrier detect thing? If so, then maybe I could directly record the modem output onto tape and then later retrieve the digital data by playing the tape back through the modem the other way. I would really appreciate any advice on this. (I'm in a crunch to get this thing operational in a few weeks.) Richard Ketcham Physics Dept.

Thanks for the note on Telekom ... it was all too familiar. Actually, I thought the author was a little too kind. He was definitely lucky on his initial install. Most people wait a minimum of six weeks. What most Americans with the military do is sign over the old telephone number from the previous tenant....that way there's no break in service. In our case it did make for some interesting calls from long-lost friends and relatives (that weren't ours) and who didn't get the word from the family that was here before us. One particular problem was the last tenant had put up notices on various bulletin boards of items he was selling due to his PCS ... it took us a few months before we tracked them all down. We don't have a touch tone phone, but we do lease the cheapest one they offer. I brought over a rotary unit that I keep plugged into my modem. One thing your note didn't mention is a big gripe of mine ... there is a big charge for having a second phone (extension) in your house ... and it's not the same as in the USA ... according to the lady that took my order, there is a law against two units listening in on the same line. With the special hardware you get with the extra phone order, if someone picks up on the extension when you're on, you get cut off while the other guy gets connected to the party you were talking to. Without this hardware, the call gets disconnected. I opted to have only one phone ... sort of interesting when your home has three levels. For this reason, I have to disconnect my phone to use my modem; however, with my rotary phone connected, if I'm not using my modem and a call comes in, I'll know about it (and I can dial out on it too). Also, the quality of the lines don't seem good enough for data at even 1200 baud. Of course, it may be an attenuation problem since my PC is about 10 meters away from the phone jack. Anyway, I can dial into work (not a local call) and CompuServe (really not local ... the closest node is in Frankfurt) which is better than nothing. Well I'm gonna wrap this up for now. Tell everyone Hi for me ... talk to you soon. ------------------------------ From: MPA15C!ARTHUR@TRENGA.tredydev.unisys.com Date: 08 AUG 92 13:47 Subject: L O U D Indoor Ringer Wanted I'm trying to locate a supplemental ringer that will enable an elderly, increasingly hard-of-hearing relative to be aware that the phone is ringing.

Segel) Subject: Neophyte Long Distance Questions (Technical) Organization: Storage Dimensions, Inc. Date: Sat, 08 Aug 92 07:18:06 GMT I have a few questions about just what is going on when I place a call from work (near San Jose, CA) to, say, Japan. There are two major variables that seem to change for every call I make. Number one is that sometimes there is a long delay between what I say and the answer I get from the other person, which can lead to real difficulty in carrying on a conversation. This delay is not always there, however. Secondly, the line noise is sometimes considerably higher than other times. Is this in some way related to calls going through a satellite versus going through cables under the ocean? What are the distance involved? I thought the satellite were in geosycnhronous orbit about 22,000 miles out, but even that distance should only delay the signal about .25 seconds (there and back). Is one method of carrying the signal inherently more noisy than the other? I'm fascinated by how the signals get shuttled around, so anyone that has any info they could e-mail me or post would be greatly appreciated. On a side note, does anybody know if the beeps you hear while waiting for an international call to complete mean anything? Thanks, Daniel A.

I just heard an ad that said, "Priority Ringing - another new idea from Pacific Bell." How about, "another new idea *for* Pacific Bell"? Unfortunately, the general public does not know that CLASS services have been available in states other than CA for years, so people may actually think that Pacific Bell came up with this wonderful idea and we'll be the first state on the block to try it out. (Doesn't everyone read TELECOM Digest or crack open the phone book as soon as they get in their hotel room if they are traveling? :) While they're so full of new ideas, why doesn't Pac Bell offer Ringmate/Ringmaster (we have no name for it since it's not offered)? I wanted to have a phone number other than my regular home number for a different use, but have it ring on the same line. Since Pac Bell doesn't offer this, I ended up having an extra line with call forwarding installed and just forwarded all calls to my regular number (the only way I can tell which number was called is if I hear the forwarded number ring once first). A friend of mine pointed out that GTECA does offer SmartRing, and that I ought to ask Pac Bell why they don't offer a feature that "even GTE, the laughing stock of the telecom industry" offers. Jeff Garber My opinions are just that. ------------------------------ Date: Sun, 9 Aug 1992 03:05:51 GMT From: ricochet@spatula.rent.com (Rick O'Shea) Subject: What Number am I Calling From?

Not really. The FCC does keep track, but it does not make them easily available in an easy-to-read format (it also does not make them available frequently enough). PUC's are useful for intrastate rates. 2) Is there a better way to get current rate info? Not easily. Several people suggested putting together a set of representative test calls and asking each carrier for rates on those calls. One person suggested that I might have more luck asking for a fax copy of ratesheets. 3) How can I use more than one carrier for a single phone? I should have known this. Everybody who replied reminded me that if you are in an equal access area, then you can use Feature Group D to select carriers on a per-call basis (Feature Group D is 1+0+3 digit code, a la 10ATT, 10222 10333 . . .) Several people reported that they pick and choose on a per-call basis. 4) Is there anything other than rate that should affect my decision? Customer service, calling card surcharges, and convenient discount periods headed this list. A few people had customer-service nightmares to share. 5) Are there non-big-three carriers that I should be considering? John Higdon pointed out that some minor carriers beat the majors in signal quality to certain places (Hawaii, in his case). John Saker (who is not happens to be an employee of a smaller carrier) said that smaller carriers are a good idea for some calls. He suggested that the state PUC telecom tariff division was a good way to find the IXC's operating in one's state. There is also a file with FGD codes for a whole bunch of these carriers at the telecom archives. 7) 800 Numbers John Higdon suggested that business (as opposed to personal) 800 can be a better deal. Several others pointed out that there was a chance that this would be more expensive, and Gordon Burditt pointed out that one must pay for 800-wrong numbers (He brought up the nightmare of having a misprinted ad point to one's personal 800 number). 8) Is there a substantial price difference among the big three? Not much. I would summarize some of the additional info that John Higdon sent me, but he posted it.

He wants to install one set of A Links to an STP pair in one LATA so that the SS7 signaling for both LATA's can be handed to the IXC's there. I am having a hard time finding anyone that has any direct knowledge of whether the RBOC waiver request allowing this to be done has been ruled on or not. It was my understanding that the original rules would require two sets of A links, one to each LATA STP pair since the RBOC's would not be able to carry SS7 messages across LATA boundaries. Athough this scenario would not necessarily require this to be done if all carriers exists in both LATAs, I am not sure what the original "intent" of the rule was to be. Should a carrier in LATA R (for where the remotes are) not have SS7 links in LATA H (where the host and A links are) then the signaling messages would need to be carried across the LATA boundary and the rules would apply for sure. I need to know what the status of all this is. At this point, even any surmises as to possible outcomes would be welcomed :-> .

He is presubscribed to AT&T and all, 700s are not blocked from his line, etc., yet when he dials 0-700-my number, he gets an AT&T operator who instructs him to (incorrectly) dial "1" first, which of course won't work. I called AT&T about this, and after being told some silly story about how Rochester Tel has no OSPS links to AT&T's network (which is absurd -- they have had them for years), and calling Rochester Tel to confirm that this was not true, I was told that the "real" reason why EasyReach calls couldn't be placed from SOME exchanges in Rochester Tel's area is that they aren't running the proper software on their ATT 5ESS machines. The technical rep at AT&T EasyReach said that he was aware of this problem, and that they were working on it to try to patch it up. My question is: Why is the software that Rochester Tel uses on its 5ESS machines any different than what a BOC (like New England Tel) uses? Is this really a correct answer, or just another one of AT&T's stories which they liberally employ to get rid of (legitimate) concerns regarding their service? I am generally quite happy with AT&T EasyReach ... it is an exceptional service. Yet not being able to be reached from the second largest city in New York state (at least in certain exchanges) is troubling. AT&T should act quickly to remedy this shortfall. (And yes, I know about their 800-824-5621 number, which can also be used for regular Calling Card calls; it is too much of a pain to give BOTH the 800 and the 700 number out and expect people to reach me that way.) BTW, two of the exchanges in question were 716-461 (Field St. CO) and 716-263 (Stone St. CO). AT&T says there are many more :( Doug dreuben@eagle.wesleyan.edu // dreuben@wesleyan.bitnet ------------------------------ Date: Sun, 9 Aug 92 00:43:33 CST From: Jack Decker Subject: Carrier Access Codes in Northern Minnesota I don't recall offhand who was maintaining the list of carrier access codes, but a week ago I was in Northern Minnesota and happened to pick up some literature from one of the local phone companies (Consolidated Telephone Company, Brainerd, MN) that listed the XXX codes for the long distance carriers serving their area. Obviously, some of these are national carriers but others are locals that may not already be in the list. Since this is a small, independent telco it is somewhat amazing that they have this many choices! Here's the list: AT&T 288 Allnet 444 ACI 244 Bemidji Long Distance 499 (Bemidji is a small town in Northern Minnesota) Cable and Wireless 223 Coast International 063 LDDS (Mid American) 001 Long Distance USA 252 MCI 222 Metromedia 488 National Teleserv 401 Polaris Telecom 264 (owned by Consolidated Telephone Co., Brainerd) Telecom USA 835 Telephone Assoc 837 US Link 355 (owned by Arvig Telephone Co., Pequot Lakes MN) U.S. Sprint 333 I might also mention that there are a couple of carriers in Michigan that did not appear on early lists, but that may have been added later: Superior Telecom 232 MetroNet 258 Interestingly enough, in northern Minnesota you can choose one carrier for your intraLATA calls, and a different carrier (if you want) for your intraLATA calls, so apparently there is both interLATA AND intraLATA competition there. Oh, one other interesting thing: I mentioned that Consolidated Telephone's offices are in Brainerd. But, they are NOT the LEC that actually provides service to Brainerd. Instead, that is provided by U.S. West. Consolidated actually serves many of the smaller towns that surround Brainerd, and I suppose they felt that it was more advantageous to locate their office in the central city than in one of the outlying areas. Interestingly enough, their office is only one block from the U.S. West exchange building (which no longer houses a business office). I've noticed this in a few other cities, where an independent telco will have their offices close to (or even next door to) a Bell building, but in most such cases the independent serves the town, leaving one to wonder what the Bell building is doing there! I'm sure there are historical reasons for things like that, but it really makes you wonder ... I mean, you'd think that if Bell were going to go through the trouble of building a switching center, they's also serve the community; and that conversely, Bell wouldn't be much interested in building a switching facility in "foreign" territory. As I say, it makes you wonder ...

The first thing I noticed when I "deplaned" was the ugly new British Telecom logo on the phones. According to friends I visited, BT spent millions on converting to the new logo. What a waste. Several phone box thefts were in the paper while I was there. A while back, BT installed hardened coin cases in their pay phones to prevent thieves from drilling them out and stealing the coin boxes. Unfortunately, apparently, BT often lost the keys to these boxes and had to drill them open themselves. So they had the coin boxes built with three areas where the steel wasn't reinforced and could be drilled. The template used to drill holes has fallen into the wrong hands, and now coin boxes are being hit all across the country! My friend recently received a new touch-tone leased phone from BT. He had called and asked for one earlier, but BT denied him, saying that his old set would have to be busted before they would replace it. So, several "accidental" drops of his old set on the floor later ... USA direct now allows you to dial the number you are calling and punch in your calling card number yourself, without operator intervention. This worked great from my friend's touch-tone phone, but not from any pay phones. They are push-button, but still pulse out the number you calling. After I got the prompt, I dialed the number I was calling, and had to wait as it pulsed the number out. After it was done, I heard the operators chatting with each other. Apparently, this happens quite often, and the operators have to wait for the pulses to stop before asking you for the info manually. I wonder how much operator time is wasted on this. I found out later that you can enable the touch-tone pad on BT pay phones after call completion by pressing the * button. I tried this at the airport while I was waiting for my return flight, and it worked! However, the tones were too short to grab the attention of my answering machine. This "feature" is not documented on any of the pay phones I used. I used Sprint Express to call my work everyday and AT&T to make personal calls. Every call I made using Sprint was crystal clear. Every call I made using AT&T had some sort of problem. The most frequent annoyance was loud hissing whenever the party I called wasn't speaking on the other end. I had one call where somehow, the last 1/4 second of each phrase spoken by the called party was lost. This meant the last word or two of every sentence was lost, and we found ourselves saying STOP before every pause just to be able to understand each other. I can't imagine what was happening. The best clue I have was that the voices were digitized and sent via packets, and the last packet in a series was being dropped. ------------------------------ Subject: Overseas Calling Cards Date: Sun, 9 Aug 92 16:03:21 NZT From: lchiu@animal.gcs.co.nz (Laurence Chiu) Has anybody had any experience with overseas calling cards issued by either MCI or ATT? -- cards that can be used by non-US residents and which can be billed to a credit card. I have applied for cards from both ATT and MCI by just calling the local USA Direct number for ATT and MCI (Call USA) and having them transfer me to the business office. Interestingly enough ATT said they would send me out an application form while MCI took the details over the phone and even gave me a local toll-free number which would connect to the US business office. ATT have given me no rate information yet and MCI have given conflicting information each time I call them. But what is most useful is MCI say they will charge only US$2 for a call to a US 800 number, irrespective of the provider and time spoken -- that will be very useful. Anybody using any of these cards who can supply rate information and/or any other useful tidbits would be much appreciated. E-mail is okay, I will summarise if there is enough interest.

Would it be _technically_ feasible (with telco cooperation) for all telemarketing calls to carry a unique Caller-ID (or perhaps come from a unique prefix like 800 or 900?) independent of the lines on which the calls actually originated? If so, then given suitable legislation mandating this, telemarketers could dial away at will, while callees who wished could easily block access without impact on their other phone usage. Direct cost to the marketer for such an arrangement should be low; option and responsibility for blocking would be entirely at the receiving end. So, is the concept technically possible?

So far the school has been unable to use all the equipment because they would be overwhelmed by the phone charges. I've suggested that she considered run her own leased data line locally. I don't know the economics of this and am interested in other alternatives. What are the charges and issues associated with a microwave link. Obviously school systems are very price sensitive but it is more likely to be able to get equipment donations than service donations. Ideas? There are really two questions here. One is the special case ideas where begging is an acceptable form of purchase. The other is the more general question of how to deal with a pricing system setup for POTS and business when attempting trying to access remote services. Of course, minimizing communications through local caching and compression software is a good idea, but I'm not proposing a major development project at this point. ------------------------------ Date: 09 Aug 1992 01:59:27 -0500 (EST) From: BOB VOGEL Subject: Old Dogs Learn Faster!

From "Peak Learning" by Ronald Gross p24++: "We used to believe that the brain developed to a certain age and then stopped and began to die. This made it easy to believe that learning was the province of the young and that, as we grew older, we began to lose our knowledge. ... First, the brain is now pictured as constantly growing. ... The crucial lesson here is that despite our traditional beliefs about old dogs learning new tricks and our increasing apprehensions as we grow older about premature senility whenever something slips our minds, our brains can continue to grow throughout our lives. For that to happen, however, we need to create for ourselves the human equivalent of Diamond's enriched environment. ... our enriched environment must include constant stimulation from new ideas and understanding, and from all the other challenges and opportunities offered by the best that humankind has thought, felt, and done. ... Aging per se does not undermine learning capacity; *attitudes* and *life- style* do that. 'Use it or lose it' applies to your brain as much as to other parts of your body." How do we enrich our brain? By reading TELECOM Digest, of course. And the 80+ year olds probably get more out of it than anyone younger can.

The union, Communications Workers of America, is seeking better job security, higher wages, expanded training programs, improved health care benefits and better working conditions. The five companies are Ameritech, Bell Atlantic, BellSouth, Pacific Telesis and Southwestern Bell. The contract for workers at a sixth regional company, US WEST, expires August 15. An agreement with a seventh, NYNEX, was reached last September. Saturday's deadline affects about 219,000 workers, the CWA said. Some 39,000 workers for US WEST have authorized a strike if a new contract agreement is not reached by midnight August 15. Negotiations were underway Friday in Atlanta; Chicago; Oakland, Calif.; St. Louis; and Washington. Union leaders have accused the Bell companies of eliminating union jobs, excluding union members from jobs in their growing subsidiaries and reclassifying union jobs under management titles. Bargaining talks, which began in June, were expected to continue through Saturday, "and probably will go down to the wire," said CWA spokeswoman Gaye Mack. -------------------------------------------------- Negotiators for five regional telephone companies and unions representing 219,000 workers across the nation continued talks Saturday on higher pay and job security in the face of midnight strike deadlines. Both sides said they wished to continue talking and strikes were unlikely. "We do have a 30-day agreement that there will be no strike or lockout," said Jennings Wooldridge, a spokesman for the Communications Workers of America in St. Louis, where the union is holding talks with Southwestern Bell. "They'll stay at the table until they hammer out an agreement." Similar negotiations were underway in Washington, D.C.; Atlanta; Chicago; and Oakland, Calif., between four other so-called Baby Bell regional phone companies and the CWA on new contracts. Contracts of workers at the companies, Bell Atlantic, Ameritech, BellSouth and Pacific Telesis, also were due to expire at midnight Saturday. NYNEX, in the Northeast, settled last September and the unions' contract for US WEST expires Aug. 15. The unions represent workers that include operators, cable installers, switching equipment operators and Yellow Pages advertising salespeople. The companies have said managers are prepared to step in to provide telephone service if employees walk off their jobs. Negotiators for Bell Atlantic and 52,000 East Coast telephone workers represented by the CWA and the International Brotherhood of Electrical Workers still had "substantial differences" on key issues of pay, pensions and health care benefits, Eric Rabe, a spokesman for Bell of Pennsylvania, said Saturday night. "We wish we were a little further along than we are now," Rabe said. Bell of Pennsylvania is one of eight Bell Atlantic companies involved in the talks in Washington. The other companies are in New Jersey, Delaware, Virginia, Maryland, West Virginia and Washington, D.C. Bell Atlantic negotiators have offered pay increases totaling 11.4 percent over three years and a 12 percent pension increase effective next Jan. 1. The unions have balked at a company proposal to require future retirees to help pay for their health care benefits. Another issue unions were resisting is a company proposal for "incentive pay plans" which call for some sales employees to do without automatic annual pay raises. Last week, the unions authorized a strike if new agreements weren't reached before three-year contracts expire at 11:59 Saturday night. In Atlanta, negotiators for BellSouth and the CWA continued talks aimed at averting a strike by about 62,000 employees in the Southeast. The two sides were trying to settle disagreements over wages, health benefits and the subcontracting of jobs to non-union workers. The union and BellSouth remained far apart on many issues, CWA spokeswoman Nettie Walraven said Saturday night. In Chicago, an Illinois Bell spokesman said talks for the five Bell companies operating under Ameritech were being handled separately. ------------------------------ From: Phillip.Dampier@f228.n260.z1.fidonet.org (Phillip Dampier) Reply-To: phil@rochgte.fidonet.org Date: Sun, 09 Aug 1992 13:23:08 -0500 Subject: Agreements Reach at Two Tel Companies AGREEMENTS REACHED AT TWO BELL OPERATING COMPANIES, TALKS CONTINUE AT THREE OTHERS WASHINGTON -- (11:00 am EDT 8/9/92) Union and company negotiators at five regional Bell telephone companies either reached tentative contract agreements or continued talks past the midnight August 8 deadline. Some 219,000 workers represented by the Communications Workers of America are affected; another approximately 14,000 are represented by the International Brotherhood of Electrical Workers. Tentative agreements have been reached at BellSouth and Southwestern Bell. Talks are continuing at Ameritech, Bell Atlantic, and Pacific Telsis, slated to resume this morning. Details of the tentative agreements at BellSouth and Southwestern Bell will be released as soon as they are available. The CWA contract with U S West, covering 39,000 workers, expires on Saturday, August 15th at midnight; talks continue there. NYNEX, the seventh and last Baby Bell company, reached tentative agreements with CWA and IBEW in September, 1991. Major stumbling blocks to agreements at Ameritech, Bell Atlantic, and Pacific Telesis lie in the areas of health care, wages, and pensions, according to union negotiators. Negotiatiors at those three companies agreed to "stop the clock" on contact expirations, leaving workers (116,000 CWA, 14,000 IBEW) still covered under those contracts. ------------------------------ From: gmw1@cunixa.cc.columbia.edu (Gabe M Wiener) Subject: Need 66-Block Help Organization: Columbia University Date: Mon, 10 Aug 1992 03:19:04 GMT Can someone give me a crash-course in 66-block wiring? I need to shuttle some lines from one end of a facility to the other, and there are 66 blocks at both sides. This is what I have always assumed about 66-block wiring. If any of my assumptions are wrong, could someone fill me in? - The clips in a given row are connected to each other. - Tip is wired over ring - A particular row is "free" if it is connected at one side only. If there is only one wire in a row, there's nothing connected to that pair, at least at that block. - Tracing a particular pair involves putting a tone genrator on one side, and then waving an inductive probe around on the other end until the matching pair is found. - Wires do not need to be stripped before being punched in, since the clips will break through the insulation as the wires are punched down. Questions: - Is there any significance to the colors in a 50-pair cable? (i.e. are certain colors used for tip/ring or for certain line numbers? Or are they solely for the purpose of differentiating one from another in the cable?) - Sometimes I see more than one wire punched into the same clip when there are vacant clips in the same row. Is there any reason for doing this? - When running down a 66-block with one lead of a test set, what's the best thing to do with the other lead? Just ground it somewhere? or connect it to the other side of one of the lines in the box? Any other tips in this sort of work would be appreciated. Gabe Wiener - Columbia Univ.

The phone lines that run to my house have rotten equalization, primarily due to the length of the run from the central office. The phone company has made measurements and confirmed that there is a 10 db drop from 1000HZ to 2600HZ, and that's more than enough to drive v.32/v.32bis modems up the wall. Their solution is a data line at about $30/mo, I'm looking for a simpler solution. I suspect if I could come up with a equalizer to minimize the variation across the frequency spectrum, my problem would be greatly minimized, or perhaps solved altogether. What I'm looking for is someone that knows where I could procure such a device, and how much it might cost. I'm also looking for a source for actual specifications of a voice grade residential line, seems it's like pulling teeth to get one from either the phone company or the state PUC!

Or is the fiber paralleled with current-carrying wires to > provide CO battery to the drops?) In our neighborhood, we don't yet have fiber, but we do have T-1 digital circuits. The same considerations apply here. The T-1 circuits don't deliver loop current, but each one does deliver up to 24 voice channels. They don't run the T-1 into homes. They sometimes do run it into offic buildings where it terminates on a PBX or a channel bank. The channel bank is locally-powered, and de-multiplexes the T-1 into a bunch of Tip and Ring analog circuits. The PBX de-multiplexes, and provides dynamic switching between the derived voice channels and extension telephone sets. In the residential neighborhood where I live, there is an underground vault containing several racks of channel bank equipment. It is known as Subscriber Loop Carrier, and we happen to use a 96-channel version of the product, which AT&T calls SLC-96 (pronounced 'slick ninety-six'). The SLC-96 may be engineered to be blocking or non-blocking. If there are more than 24 derived analog lines per T-1 span, then it is blocking. Signalling channels between the SLC-96 and its companion unit at the CO (or the CO switch itself, in some cases) control who gets connected to each derived channel, when call-setup is done. The SLC-96 is powered by the local power utility, and has self-contained storage batteries. When there is an area-wide electrical failure, the local phone service lasts four-to-eight hours, probably depending upon traffic and how long it has been since the last outage. (Yes, there is a watt-hour meter near the street access to the vault.) The SLC equipment is designed to work with T-carrier or fiber and it makes no noticable difference to the subscriber at the end of the local analog loop.

That sets the "How long should I wait before hanging up if the other carrier disappears" register to indefinate. Changing S9 determines how long a valid carrier has to be present before the modem will respond. Once you set those values, just do an ATX3D command (the X3 will prevent prob's from no dialtone being present) and whistle briefly into the modem to make it think there's a carrier present. It will respond and continue to do everything as if it were connected with another modem without hanging up with S10's new setting. AT&C will cause the modem to give a false positive carrier detect signal back to the computer if the terminal software there depends on that to know when it's connected. The pitch you whistle will control the type of carrier the modem responds with (300/1200/2400), so if you have trouble getting the one you want, set your terminal to the proper baud rate and use another tape recorder to record the tone produced by an ATA command and play that back to trick the first modem into starting its connection sequence. This is all assuming, of course, you've got some kind of acoustic cup or telephone-like path into the modem (you can test this on your own phone line by taking the phone off the hook and waiting for all the recordings and warning signals to go away and using that phone for tape recording and playback to the modem.) I've successfully tape recorded and played back modem sounds at 300 baud before ... even recorded a blurb announcing that my BBS was down temporarily and put it on my answering machine once. When people with modems would call, they would get the ASCII message from the recorded modem tones exactly as if they were connected to another computer. I think I tried using 1200 baud once, but it was too fast for the tape recorder to keep up with and data was garbled or lost. Using just this simple system, you might could play with the software-selectable baud rate between 300 and 1200 to find one that's a good compromise between accurate and fast. Then again, the frequencies used by the 1200 (and 2400) carriers may pose some problem as far as being accurately detected and recorded on normal audio tape -- I don't know. Note you don't even need another modem with the system you described just to store the info ... select a low baud rate for the device that is designed for connection to a modem, and send its output straight to a tape recorder. If *it* does its own checking for the presence of another carrier, the problem may be a little harder to solve if you can't control it's modem parameters with the commands I described above to disable this check. I wasn't clear about if the sensory device you're wanting to interface has a simple serial output or if it's somehow connected with a Hayes-like ASCII command-configurable modem itself. Even better, why not just get a laptop computer with an internal HD and modem that could easily be configured in a similar manner to disable the drop-carrier operation, if that'd even be necessary. Could then store all the input on you hard drive for later analysis. Doing this might be a lot easier! If the device you're wanting to record the output from has a serial output connector, you could just use a null modem adapter and not even worry about using modems at all. Hope this helps some.

In the audio track, we sent some ASCII identifing the digital data through an old Hayes 1200 modem into the audio port of the VCR. You should be able to set the modem up to leave the carrier on all the time. To record the digital audio onto the VCR, I think we used a Sony PCM box. I didn't write any of the software to talk to the modem; I don't remember who did it else I would give him credit and maybe you could contact him. I imagine you could use any standard old comm program and just type at it. Alternatively, you could program some function keys for predefined strings to send out. Also, some terminal emulator programs can program the keys to send the current time, date, etc. I think Telix can. Alan Edmonds Texas Instruments, Inc.

This modem didn't require anything to be done with carrier detect. A 4-wire 1200 bps leased-line modem isn't useful for much these days, so I was able to buy several of these modems from surplus equipment dealers for under $50. 202 modems have been used in radio paging systems for years and can often be found at hamfests. I picked the 202 because it is a "dumb" modem that doesn't need Hayes commands to turn it on and because it doesn't need to long train with a similar modem to start putting out data. The 202 will go up to 1800 bps. As I recall, the Hayes Smartmodem manual had a page in the back that told how to connect the Smartmodem 1200 to a 2-way radio. This setup might also work for a tape recorder.

The "challenge" is actually timebase-driven; there's a clock on the card which is used to determine the pseudorandom number to be displayed. The authentication hardware also has a clock; it also can derive from experience the drift rate of each card. I have one of these cards, and they work quite well. There's a display capable of showing an eight-digit number (mine only displays six; I suspect this is a parameter which can be changed when the card is programmed at the factory) on the card, and no other controls whatever. Your objections about cost and the fragility of the card are right on the mark, though. The cards aren't cheap, and they certainly won't withstand being carried around in a back pocket. Interestingly, they're DESIGNED to self-destruct if disassembled. This isn't an idle threat; I took the cover off of one of these card and it promptly stopped working courtesy of electrical contacts on the cover/label which I removed.

The problem with this method is that if call doesn't complete for whatever reason (busy, no answer, etc.), there's no way to get a refund of your entire amount if it's over $3 or so. The totalizer in most Bell payphones will only hold that much, so the operator must collect the money into the coinbox before more than $3 is collected. So, and interesting problem is created. The operator can: 1. Collect the entire initial rate before completing the call, and possibly offer a telephone bill credit in the event of an uncompleted call. This not only requires that the caller have a telephone bill to credit, but is "rude" in a sense, since the caller has deposited cash, but has to wait for a refund. 2. Caller deposits $3, the operator completes the call and tells the called party to hold while the operator collects the $3, and the caller deposits the remainder of the initial rate. This doesn't work in the case where the operator doesn't speak the same language as the callee, as they may hang up. 3. Same as 2, but operator allows caller to tell the callee in their native language to hold the line while the caller deposits the rest of the initial rate. The operator may not like, or even allow, this option, as there is the risk that the caller will deliver a short message then end the call, without depositing the remainder of the initial rate.

This situation is somewhat more involved than initial reading would indicate. Yes, the telco is right about not having the same telephone number ring in two different locations, at least in this situation. They are not doing a very good job of explaining why, however. The telco computers will not keep track of inside wiring. Although two of the locations are 1/4 mile apart, the way the subscriber shows the service being installed, this is still no different than the inside wiring between your kitchen and living room. So there is no way for the telco to specify on the service order to have this wiring installed. Without the wiring, you won't get the same number at two premises. The other obvious way to get this would be to order an off-premise extension. This would give the telco computer another circuit against which facilities could be assigned. This, however, will also raise the costs of the service to the customer. As far as the Moderator's service during moving was concerned, the computer probably handled this as a disconnect view and an add view against the same circuit. Although both cable pairs may have been direct bridged and in service at the same time, the computer is set up to handle a situation such as this. It should be noted that this is not an ideal serving arrangement. We have had situations with extreme transmission and signaling impairments occur. In my opinion, this should only be used as a transition tool and only after proper operation has been confirmed empiracally.

A recent post described the difficulty the poster's friend was having wiring three buildings located some distance apart to the same phone number; the LEC refused to do so, saying it wasn't possible. Pat added a note that not only is such an off-premise extension possible, but he has used it when moving. How did you ever convince your LEC to do that? Whenever I've moved, GTE has insisted that they could not have my phone working in both the old and new apartments at the same time; they could only turn it off at the old in the very early AM and it would be on at the new "before 6 pm."

Previously, a move always meant a call to repair and a visit by a repairman, who would spend hours finding and fixing the problem.

I've been following this thread waiting for someone to say "No, do not use abrasive cleaners on electronic contacts". No one has, so I will. Do not use abrasive cleaners on electronic contacts. On my ATT 5200 cordless phone, the charging light will sometimes fail to light when the handset is in the cradle. Everytime, without fail, it has been sufficient to use a paper towel or tissue with a little alcohol to clean the contact. Using an abrasive cleaner on any kind of electronic contact is apt to remove protective platings and cause more trouble in the future. Dana H.

You're attacking the 30 microns of gold plating with emery cloth? About two swipes and it's gone, then you'll have even bigger problems! I occasionally use a mylar eraser on contacts, the bigger reason not to use a standard pencil eraser is that it can also remove the thin gold plating in short order. The proper method is to use a non-abrasive solvent, but I don't often have that laying around in my toolbox.

This posting provides a summary of the responses. Any additional comments are appreciated. The question was as follows, > I need help on the following: I need to know how certain > organizations charge for use of their network gateways (gateways join > two systems/networks together, usually at the midrange or mainframe > level e.g. at the Front-end Processor).

We charge what the market will bear :). That means some flat rate services, and some metered services. In any case there is a fixed monthly charge and (if it's metered) a charge based on connect hours. The idea is to give people proper incentives to not use up scarce resources without paying for them. The most obvious scarce resource here is the modem, so we charge for connect time. Hope this helps. Edward Vielmetti, vice president for research, Msen Inc. emv@Msen.com Msen Inc., 628 Brooks, Ann Arbor MI 48103 +1 313 998 4562 Mr. Winsor at WINSOR_L@WIZARD.COLORADO.EDU writes, I do cost allocation for the central administrative computing service for the University of Colorado. We serve four campuses plus a central administration office. We allocate all costs (equipment depreciation, software, personnel, space) to about 19 different services, including communications. We would like to base the communications allocation on connect time and megabytes transferred, but don't have the data. Instead we use a "logon day" basis. If someone logs on once or 100 times in a day, they incur one logon day that gets added into the allocation basis for their campus. Mr. Israelit writes, First, let me explain that I am in business school at the MIT Sloan School and that, as a result, I am probably going to suggest something that is not in common usage. I have an interest in Microeconomics and feel that a practical appplication of this subject could help you out. To maximize the profits for a project of this nature you should charge a two-part tariff. Basically, this will be a one-time fee and per connection charge. This is because there are probably users with different levels of demand for your services. Using basic micro, you can set the tariff at a low enough level such that you will attract a large number of subscribers and set a fee such that you will have a high level of the usage profits. These levels are selected to maximize the total profits of the project rather than maximize the gains from either the tariff or the fee alone. I don't know if this sounds like something you would like to pursue. It does require that you have an estimate of the market demands from different users. If you would like to discuss this analysis further (free of charge) let me know. By the way, I am only at Intel for an internship, and I will be bac in Boston after the middle of August. Sincerely, Sam Israelit Engineer, Businessman, . . . Brewer Portland, OR sami@scic.intel.com Mr. Hines writes, This question is very closely associated with how organizations budget. If the organization views the computing resource as "infrastructure" then it usually is funded centerally - that is to say the providor pays for everything, do not recharge, and their operating budget is adjusted upward to absorb the costs. This is the most simple arrangement. If the organization views the computing resource as a "utility" then it usually expecte the provider of services to establish a fee structure to recover the operating costs (i.e. break even). In this case, the provider has to make up the rules. It is most "user friendly" if it is in terms the user can relate to. Charging for background resources (disk space, people, etc) are more difficult. If you can base fees on "every time you hit " is costs you 25 cents -- that is something they can relate to. Of course to do this, the provider has to have a very good understanding of cost accounting and fixed and variable costs. Of course there are all kinds of variations to the "utility" scheme. Part of the costs may be subsidized by central services (a hybrid "infrastructure" and "utility"). Our data center charges for teleprocessing by establishing classes of service based on "number of 's pressed. They have established low, medium, and high use classes, and set fixed prices for each. The class a person is charged for, is determined from prior year history. The first year the person is placed in the low category. We are using a hybrid system -- with some costs supported as infrastructure, and some recharged as a utility. The allocation seems somewhat arbitrary, but they maintain it is negotiated. Again, it depends on your budget structure. Internet: mshines@ia.purdue.edu Michael S.

We've recently gone through a lengthy and painful experience deciding how to charge for usage of the EDI system. In the end we adopted a scheme similar to what the VANs use -- costs charged are based on usage, measured as the amount of data sent/received. Our EDI service is MVS batch oriented, so this was the easiest way to measure. My key issue is that the cost of collecting data for charging costs not exceed the revenue to be generated. It seems silly, but it is easy to lose sight of this. Regards, Bill Laidley EDI Expert Team BC Systems Corp. Vancouver (604) 660-9705 WLAIDLEY@BCSC02.BITNET (Bill Laidley) Lastly, Mr. Mcguffin writes, I helped one of my clients develop a costing / charging model for use of their multi-platform service bureau and national computer network, so I have some experience in this area. Some specific responses, and general comments: This depends on the type of business, and their relationship with their clients (e.g. is it just internal charging, which is more like cost recovery, or is it a fee for service business). I am almost certain there is no "standard" way for doing this, since it really depends on what the "business objective" is of charging, plus any business or market constraints. This will naturally vary between companies. > All these questions ask: HOW is the gateway charged. But I also need > to know, if possible, WHAT the charge is based on: what cost items do > they include in maintenance of the gateway and what percentage of > these cost items is used. Cost items include: human resources, CPU > time, memory, software development, and other overhead items. Again, "it depends". A charge doesn't actually have to be based on anything, other than what the market will bear. You can simply charge $2/whatever, regardless of what it costs you to provide each whatever. This is different from what it _costs_ you to provide each whatever. Cost is important to know in order to run your business, but may only slightly influence what you charge. To figure out what items are included in cost (and maybe, therefore, the charge), cost accounting principles come into play. All of the things she mentioned are fair game in determining what it costs to provide the gateway services. Some have a nice direct relationship to each unit of service, while others (like fixed overheads) can only be assigned arbitrarily. Assigning costs between services can be a real headache, and depends on what "resource measurement units" there may be kicking around for the resource in question. For example, you may have a record of CPU usage by user, so you could apportion that way. Network packets may or may not be accounted for by network devices, and may or may not have adequate identification as to who originated them. Humans may keep time sheets, but how do you allocate the "operating system upgrade" project to the gateway versus the other projects using the machine. There's lots of room for different opinions here. > Any ideas from anyone who is familiar with this area would be > appreciated. Any information on books or papers covering this topic, > or firms doing similar work, would also be appreciated. I haven't run across any reference material in this area. Bean counters (I am one) tend to have great difficulty with the technical issues surrounding cost accounting for computer resources. Info systems people (I'm one of these too) tend to be put off by the whole process of accounting. So I don't think that there has been anything definitive put together on either side. My advice for your friend would be to start with the business reasons for "charging" for the gateway. Is it really cost recovery? Is it to make a profit from gateway services? In either case, what are we trying to do (e.g. allocate costs to other business units? justify new hardware? get people to use the gateway? not use it? attract new customers? get customers to use it differentyl, like more off-peak time vs. peak time?) These and other questions should drive the process a great deal more than what other companies do. Next, look at the technical constraints. What resource usage is actually measurable, and how can they be attributed to different users? Will measurements (e.g. transaction counters) adversely affect performance? Do we need to be able to prove measurements (as in an audit)? What will doing all this cost in equipment, software, people's time. These may dramatically limit what can be done. Then, devise a model for how the charging mechanism should work, and submit it to many sanity checks, walk throughs, etc. Once something is decided on, planning for its implementation will invariably take longer than everyone thinks. Things like beginning data collection (resource usage, costs), developing systems to process the data collected, etc. can take time. Also, make sure all affected parties are involved..the accountants and the systems people ... in making a decision, and implementing the results. I have no idea if any of this helps. I've made all sorts of assumptions, none of which may be valid. But perhaps it may give your friend some structure or direction to work with. Regards, Craig McGuffin, C.A. C.R.

The amateur (Grab can of worms. Look for can opener.) I am also active in Fidonet (NEC 285) and the possibility of moving Fidonet Echomail (similar to Usenet news) via packet radio has been discussed ad infinitum and has even been tried a number of times from what I understand. The issue that seems to surface when this comes up is that of content (I'm not a ham, nor do I play one on a BBS) as I understand that anything not totally g-rated cannot be sent over ham radio. Other issues are confidentiality (it is my understanding that ham radio traffic must be unencrypted and subject to listening by all) and borderline-commercial/blatantly-commercial material that passes through the Fidonet channels. (The issue of commercial material has been a hot one in Fidonet, even when regular dialup circuits are used.) There have been other ideas, such as spreading echomail by satellite (similar to the Usenet project now underway) or possibly using a little- known license-free band for local one-way echomail distribution. It always comes down to the same bottom lines (in the conversations I have been involved with) and that is that Fidonet will most likely continue to use dialup circuits for transport of most of the material for quite some time.

Pacific Bell has requested a rehearing on the PUC restrictions. PacBell's proposal will eliminate important safety and privacy protections in the Commission's order, CPSR charged. CNID allows businesses to collect the phone numbers of customers who call them. The Commission's order guarantees privacy protections for all Californians. PacBell proposes to eliminate a key privacy protection called Per-Line Blocking with Per-Call Unblocking. This feature prevents home numbers from being collected by businesses, unless the caller decides to give it to them. Phone companies would prefer to only offer per-call blocking, a scheme in which caller numbers are always given out unless the caller remembers to dial a blocking code before dialing the desired number. "If this happens, Californians will inevitably receive more junk mail, more annoying phone calls, and greater invasions of their privacy, some of which may be dangerous," said CPSR Chair and user interface expert, Dr. Jeff Johnson. PacBell claims that CNID would give people more control over their privacy by providing the phone number from the calling phone. This is the wrong technological answer to the problem according to Johnson. "What people want to know is who is calling, not what phone is being used. If my wife's car breaks down and she calls me from a pay phone, that's a call I want to answer. CNID doesn't give me any information that will help me do that." In PUC hearings held last year, Johnson accused the phone companies of designing a service that is more useful for businesses in gathering marketing data than for consumers in screening calls. Phone companies are opposed to per-line blocking because it would presumably result in more numbers being kept private, thereby reducing the value of the CNID service to business subscribers. "Phone companies don't want you to block your phone number when you call movie theaters or appliance stores. The more times your number is revealed to businesses, the better! So they oppose reasonable blocking options and are pushing an error-prone one," he said. If only per-call blocking were available, residential phone customers -- or their children, parents, grandparents, guests -- would often forget to dial their blocking code before making a call, resulting in frequent disclosure of private information to businesses without the consent, and sometimes even without the knowledge, of the caller. "Unless PacBell is willing to live within the very reasonable bounds set by the PUC decision, the concerns of Californians will be far better served if CNID is simply not offered at all," said Johnson. "Subscriber privacy is more important that Pacific Bell's profits." Founded in 1981, CPSR is a public interest alliance of computer scientists and other professionals interested in the impact of computer technology on society. As technical experts and informed citizens, CPSR members provide the public and policy makers with realistic assessments of the power, promise, and limitations of computer technology. It is a national organization, with 21 chapters throughout the United States. The organization also has program offices in Washington D.C. and Cambridge, MA.

(Of course, some U.S. telephone holding companies operate cable television companies outside the U.S., but nobody seems to have mentioned this yet in alt.cable-tv.re-regulate.) While many participants in alt.cable-tv.re-regulate feel that cable television companies are greedy and not interested in proper customer service, there is no consensus on what the solution might be. Some people want to see government regulation of cable television fees, while others think that competition, perhaps through allowing phone companies to provide "video dial tone", is the solution. It's an interesting newsgroup, and I think PAT would probably prefer that discussions about whether telcos should be allowed to offer cable television services take place in alt.cable-tv.re-regulate rather than here.

Eventually, it got into the hands of the man who had been the Republican candidate for Governor, Jon Grundseth, who stepped down during the middle of the race due to allegations of affairs, possible molestation of minors, and other indications of moral turpitude. Grundseth is still rather upset with the current Governor, Arne Carlson, who became the Republican candidate when Grundseth resigned (mostly because he claims Carlson torpedoed his campaign by spreading some of the aforementioned allegations), and sent copies of this taped conversation to the news media. Unfortunately for Grundseth, the major repercussion seem to have fallen upon him and the man who taped the conversation in the first place. There was a major witchhunt for a couple of days to determine if the DOT had been monitoring conversations because several people from the DOT had been trying to give copies of it away to the media and some politicians. That died down when they found out that it was done by a DOT technician at home. There's been some thought to prosecuting Grundseth for sending copies all over the place, but I don't think there have been any formal charges yet. bruce@zuhause.mn.org ------------------------------ From: johng@comm.mot.com (John Gilbert) Subject: Charges For *611 Organization: Motorola, Inc.

When I was on the Florida Turnpike near West Palm, I dialed *611 and got billed for a call to a local number in that area. I called my carrier and asked them to remove the charge. I explained that I dialed *611 and that I got billed for a call to the local number that *611 translated to. She didn't understand, but said that they would look into it.

It's > like putting your bank PIN right on your ATM card. Historical reasons: those last four digits were not originally a PIN at all. Up until the early to mid 1970s, calling card numbers were of the form xxx yyy yyyy zzzc. Typically xxx yyy yyyy was your area code and phone number, though various billing numbers were also used. zzz was a number (doubtless some Bell System person will remember what it was called) that identified the issuing telco. F'rinstance, cards issued by Bell Canada in area code 416 would have 476 for zzz. c was a check character -- originally alphabetic. Each year a different mapping of check characters to the rest of the number was used. When you placed a call with the card, the operator (of course automated service was far in the future) would simply check that the check character -- when the algorithm of the year was applied -- matched an appropriate digit of the number. Of course the check character changed each year, so a new calling card would be issued to every subscriber annually. They were just little paper cards in those days. Naturally security was minimal with this scheme -- it served more to prevent errors than actual fraud. With increasing fraud, the telcos decided they had to actually verify card numbers against a database, rather than doing any sort of even more advanced algorithmic verification based only on information on the card itself. There was an interim period when the check character became numeric, but was still being checked algorithmically, and an even longer period when countries outside the NANP were not equipped with database access (and hence calling cards bore two numbers, one with PIN and one labeled "International Number" with a check digit). I believe database checking is now universal.

Some 219,000 workers represented by the Communications Workers of America are affected; another approximately 14,000 are represented by the International Brotherhood of Electrical Workers. Tentative agreements have been reached at BellSouth and Southwestern Bell. Talks are continuing at Ameritech, Bell Atlantic, and Pacific Telesis. Highlights of the tentative agreements at BellSouth and Southwestern Bell are listed below. The CWA contract with U S West, covering 39,000 workers, expires on Saturday, August 15th at midnight; talks continue there. NYNEX, the seventh and last "Baby Bell" company, reached agreements with CWA and IBEW in September of 1991. Major stumbling blocks to agreements at Ameritech, Bell Atlantic, and Pacific Telesis lie in the areas of health care, wages and pensions, according to union negotiators. HIGHLIGHTS OF CWA TENTATIVE AGREEMENT WITH BELLSOUTH: Wages and Profit-Sharing CWA District Three VP Gene Russo reported base wage gains of 11/3 percent including continued cost-of-living-adjustments (COLA) over three years and profit-sharing. Employment Security A broad range of employment security provisions include expansion of the job pool for surplussed workers, a shifting of work previously done by contractors to the bargaining unit, special leave programs to reduce surplusses, and improvements in compensation for surplussed workers. A joint committee to study contracted work, with a goal of returning work to union members, will have unprecedented access to the company's files, records, and financial documents. The union considers this a major breakthrough in the industry on confronting the problem of loss of jobs to contract labor. Other Improvements Contract items improved include health care benefits and pensions, along with other gains. HIGHLIGHTS OF CWA TENTATIVE AGREEMENT WITH SOUTHWESTERN BELL: Wages & Profit Sharing CWA District Six VP Vic Crawley reported base wage increases of 12.3 percent over three years, plus additional days off with pay that give many workers an extra 3.6%; upgrades for workers in rural areas will raise their pay to the same level as urban area workers. In addition, a new "success sharing" plan will give employees $37 million in cash and/or stock. Employment Security Major gains in employment security protections include neutrality and access for organizing in Southwestern Bell subsidiaries. Union recognition in any new telephone company subsidiaries performing work currently performed by telephone employees and staffed by a majority of current telephone employees. As part of "The Strategic Alliance: Gateway to the 21st Century," a joint task force to deal with subcontracting issues will be formed. Arrangements have been made to return contract work to surplus craft workers. Other Improvements Under the above-mentioned Alliance, committees will study ways to eliminate secret monitoring, sales quota issues, health care cost containment, and technological change issues. There were also improvements in health care, family care plans (including $2000 adoption assistance, flexible leave, and 50% benefits coverage during child and elder care leave), and pensions. ------------------------------ Date: Mon, 10 Aug 1992 06:17:29 -0400 From: Monty Solomon Subject: ACMS Software Helps Cellular Communications Provider From: price@mrktng.enet.dec.com (Dave Price, UNIX Press Relations) Subject: DECnews/ACMS Software Helps Cellular Communications Provider Date: Tue, 4 Aug 92 15:19:04 PDT |||||||||||| DEC n e w s |||||||||||||||||||||||||||||||||||||||||||||||| Digital Equipment Corporation Maynard, Massachusetts 01754-2571 Editorial contact: David Lynch (508) 467-7724 DIGITAL'S ACMS SOFTWARE HELPS DIVISION OF COUNTRY'S LARGEST CELLULAR COMMUNICATIONS PROVIDER MEET CHALLENGES OF RAPID GROWTH ... Florida Cellular One Turns to Digital's Transaction Processing Technology to Manage 30 Percent Annual Growth Rate, Provide Top Quality Service, Leverage Existing IT Investment ... Maynard, Mass. - July 28, 1992 -- Florida Cellular One, a division of McCaw Cellular Communications, the nation's leading cellular service provider, is building a reputation for high-quality customer service with the aid of Digital Equipment Corporation's Application Control and Management System (ACMS) transaction processing technology. The division implemented Digital's ACMS software to run customer support applications that provide on-line information related to every aspect of a cellular telephone installation. "Our ability to respond to customer inquiries in real-time gives us quite a service, support, and competitive advantage," said Michael Benson, Florida Cellular One's Vice-President of Information Services. Customer turnover in the cellular telephone industry has led many cellular service providers to place top priority on customer support as a way to attract and retain clients. "As cellular technology continues to mature, cellular service companies are turning to their information systems resources to help strengthen ties to customers," said Dennis Roberson, Digital's Vice President of Corporate Software. By meeting customer expectations for quality service, Florida Cellular One is able to maintain a standard of excellence in customer care, resulting in an annual growth rate of nearly 30 percent for the division. "As the company grows, our biggest challenge is to leverage our existing IS investment to give new service representatives immediate access to customer information," said Ed Janowsky, Division Director of Information Services-Operations. "ACMS software helps us do that." Florida Cellular One's newest ACMS transaction processing application, developed in-house, is the Service and Install System (SIS). SIS, an application that tracks equipment installation, service data and inventory control, is one of the company's strongest links to its customers. It enables service representatives to immediately address customer inquiries regarding phone installations and repairs. "Aside from the billing process, SIS is the one area where we interact with customers the most," Benson said. "It helps us respond quickly and efficiently to their needs, as we strive for 100 percent customer satisfaction." Florida Cellular One's implementation of Digital's ACMS software supports customer service representatives at 26 Cellular One locations and 100 independent distribution sites around the state, in a distributed processing environment. Transactions are processed seven days a week from customer care, sales and installation, credit, collections, service activation, and data entry users. ACMS applications are processed at the Cellular One data center in Ft. Lauderdale, where the transaction processing workload is distributed among VAX systems to share the application processing and Rdb database management and to handle all presentation services. Users around the state interact with the system via VT320 terminals, as well as PCs and Macintosh computers. Databases that support a credit application running on ACMS software reside on a VAX system. Users are linked to credit data over DECnet software. "This technology lets us easily expand our operations, "Janowsky said. "If we need to, we simply add another VAX system to handle forms processing for the new customers, leaving the VAX host system investment intact." Janowsky reported that as McCaw Cellular's Florida division continues to expand on the inherent functionality of ACMS software, the SIS application developed by the Florida group is now also being implemented by McCaw's Minnesota regional operation, and is being evaluated for use in three other McCaw regions. Digital's ACMS software is designed to efficiently develop, execute, and maintain all aspects of transaction processing. A layered software product, it is ideal for businesses dependent upon high-performance, mission-critical, and mutivendor transaction processing systems. Digital Equipment Corporation, headquartered in Maynard, Massachusetts, is the leading worldwide supplier of networked computer systems and services. Digital pioneered and leads the industry in interactive, distributed, and multivendor computing.

Just when we had heard the last of "Centrex is the only service that can keep you up and running during a power outage", we get a new attack of misleading and downright untrue statements in Centrex advertising. We hear how the March of Dimes and other prestigious charitable organizations have "selected" Centrex for this, that, or other bogus reasons. Of course, the real reason that bonafide charities use Centrex is a matter of accounting: they are not allowed to collect capital assets, such as a PBX switch. It has nothing to do with cost, practicality, reliability, or functionality. But Pac*Bell would have us believe that these well-run organizations know something that we ordinary mortals do not. In other advertising, Pac*Bell proclaims that Centrex allows inter-building communication -- something that no PBX can. How's that again? I guess the PB promotion department has never heard of short-haul microwave or even about Pac*Bell's own OPX service. I understand the pros and cons of Centrex service. No one needs to educate me on that. But Pac*Bell's efforts to push the offering as the answer to ALL communications requirements is not playing fair or even honestly. John Higdon | P. O.

We have a dead one here that can be repaired if we happily fork over something like $6000 for a replacement hard disk (the software is free :). We're still thinking about it (hint: don't hold your breath). Anyway, we were fooling around with the few files salvageable on it and were curious what encoding format the Cindi uses to store its speech files. We've exhausted the available formats on the D/40D Springboard, which I thought would cover all the bases. My friend says that the SoundBlaster has more formats available on it, but that don't help much since I don't have one. Now we're really curious. Just what the heck is the secret recipe here?

Informist monitors computers for problems or errors, and when one occurs, immediately and automatically contacts the proper personnel by phone call, pager, and other methods. The computer voice actually speaks, informing which machine is ill and defining the problem. This round-the-clock monitoring eliminates the need for periodic manual checks and reduces maintenance response time, resulting in less computer "down time" and customer service disruptions. Informist resides in the AT&T CONVERSANT(R) Voice Information System computer, and monitors itself as well as computers connected to it via ORACLE(R) SQL*Net(R). Error messages are monitored for hardware problems such as failed circuit boards, system problems such as low disk space, and communications problems such as data transmission failures. The computer's voice capabilities allow Informist to place phone calls to designated parties, speak the computer name and the type of error, and then ask for verification of the message. Other notification methods include pager, electronic mail, modem, console messages, and external monitor messages. System administrators can adapt the software to their unique needs by determining problem severity, modifying the methods of notification, and changing the destinations of notification. For additional Informist information, contact Gold Systems, Inc. at (303) 447-2837. ------------------------------ Date: Tue, 11 Aug 92 11:08:51 PDT From: HOWARD PIERPONT Subject: WE 392A Wiring Information Needed My wife claims she can't always tell which line in ringing and asked me to find a solution.

Thanks to Thomas Diessel of the Federal Armed Forces University, Munich Computer Science Department for sending this along to us. Unfortunately, it will be a while before an updated zone 4 (Europe) list can replace the existing archives one, due to some disarray and work in progress on my end of the country code listings. However, the new Germany updates will be included in a new zone 4 set of codes. dleibold@vm1.yorku.ca (list begins below...) 8 August 1992 Comments: This list is only a quite random selection of German area codes. (As the list is already quite long I suggest to delete all four digits area codes not ending with a 1.) Neither area codes nor prefixes have a fixed length. The area codes are two to four digits in the western part and two to five digits in the eastern part (3xxxx) of Germany. All subscriber numbers are three to seven digits and up to eight digits for PBX. The area code and the subscriber number together are not longer than ten digits. Most three digit area codes were of the form zX1, where z is the ZVSt (central switching office). But the number of exceptions increased over the years: 202, 203, 208, 209, 212, 214, 228, 234, 335, 340, 345, 355, 365, 375, 385, 395, 906. The most exceptions of this rule are within the ZVSt 2 because there are a lot of large cities and within the ZVSt 3 because that covers a large region (the eastern part of Germany). The area code z11 is usally the area code for the city where the ZVSt is located, except for cities which got two digit area codes: 30, 40, 69, 89.

The rep made no mention of whether the 800 number had to be an MCI number or not. While we're on the subject of USA direct services and costs, I hope some find the following info interesting. I gathered it partly from the Digest and partly from calling the companies involved. Brief summary: for calls to US from Germany of 15 minutes or less, it's cheaper to use the German phone company (Telekom) than ATT or MCI. But if you have MCI's Friends & Family service, MCI-FF is cheaper already after five minutes. This assumes that you're calling from a private phone or pay phone, not from a hotel or other ripoff setup. I don't know if the USA Direct rates vary from country to country, so these figures might be of limited use. I hope that MCI & ATT wake up and reduce the costs of their USA-direct services for people calling from Germany. ATT is simply not competitive anymore within Germany, and MCI only is worth using if you have F&F. chris ... ---snip,snip--- Calling the US from Germany: Telekom's overseas (USA) rates 24 hours/day: 1 Unit = 7 seconds = DM.23, 24 hours/day (DM 1.97/min; @USD 1 = DM 1.50, this is USD 1.31/min) ATT's USA-Direct rates 24 hours/day: $2.50 surcharge 1.77 first minute (i.e., $4.27 first minute) 1.09 add'l minutes MCI's call-USA rates 24 hours/day: $2.00 surcharge 1.76 first minute (i.e., $3.76 first minute) 1.09 add'l minutes And you can call an 800 number for the same charge (i.e., no cheaper).

Here is a very simple explaination of CDMA (Carrier Detect Multiple Access): Before sending, listen to the line, if there is no carrier, then send. This is sort of like how we hold a group discussion on the phone ... if no one else is talking, then you feel free to talk, only this is for data. It is used on any 'multi-drop' kind of line instead of polling. The carrier can be anything, from the RF carrier in a radio based application to the dc bias on an ethernet cable. NOTE: ethernet adds another feature to it, CDMA/CA (CA = collision avoidance) There is always the ability for two transmitters to decide at the same time, its free, jump on the line. This causes a collision. In pure CDMA, the collision just wipes out the data, and a timeout retry will pick it back up. Ethernet, uses CA, where each station first transmits a pre-amble before the data. They also listen to see if the pre-amble got stepped on. If it does, they back off and avoid the collision. Then the data makes it out, or everyone backs off, and a 'retry timer' is used. Sydney S. Weinstein, CDP, CCP Elm Coordinator - Current 2.3PL11 Datacomp Systems, Inc.

Disclaimer: While AT&T markets AUDIX(tm) and a host of other voice- processing systems, I don't work on or sell them (except switches). That said, I must say that the use of a single "*" or other key to erase or do anything else that can't be "undone" is, to me, a mistake. Talk-off and other studies show that human voices can imitate a frequency pair fairly often; getting two in sequence (Audix uses "*D" or "*3" for "delete") is very unlikely.

Yes, the Germans will tell you that it is "technically impossible" to have more than one extension operating on the line at one time. Bullshit. The German phones will cut off when the line voltage gets too low (second extension going off hook). They will add a second extension with the crapola exclusion device so only one extension can be on line at once. But if you put real phones (AT&T, GNT (Danish), Plessey (UK)) on the line, they will work like U.S. phones. The U.S. standard is that three 500 sets (standard rotary) can be off hook and working at once. Bugger the law, you are the customer, phones are for communication. By the way German line voltage is 60 Volts - U.S. voltage is 48. > Of course, it may be an attenuation problem since my PC is > about 10 meters away from the phone jack.

Some phones have them, most phones can have them added (otherwise known as a grey or silver box depending on whose colors you believe). Quite a few of the "smart phones" for conferencing have them (with another name). The Novation Apple-CAT could dial them, and there are several computer programs that will generate them (as well as many other telcom tones such as KP1, etc.) > What else are these extra tones used for? AUTOVON (the military) used them. The tones are otherwise designated as Flash, Immediate, Priority, and Routine (with variations). Some voice mail / company phone systems use them. It's an extra four buttons to attack commands to in addition to "*" and "#"! They used to be useful in areas that had an automatic call distributor (ACD). You'd call directory assistance (555-1212) and hold down the "D" key to knock the operator off the line ("Oh, another SOB who called and then hung up!"). You then get a pulsing dial tone that indicates that you're in ACD test mode. 6 and 7 would put you opposite sides of a loop, you could supposedly do a REMOB test which would allow you to tap phone lines using a special code and then the seven-digit phone number. Mass conferencing, etc. Even in 1984 ACDs were hard to find, however. I doubt anyone still uses them. In fact, with ESS it could be dangerous to try it. ------------------------------ Organization: Penn State University Date: Wed, 12 Aug 1992 13:01:30 EDT From: Peter M.

(And for the low price of, what, $5/mo?) And, at no extra charge, The Message Center will periodically delete a week's worth of messages AUTOMATICALLY before you even have to listen to them. Now that is truly a time-saver! I want you to know that in me, you are dealing with the consummate telco-service-gadget freak. Throughout my life, I have ordered every single service available from the phone company if for no other reason than to see how it worked. Every service Pac*Bell now offers is available in my area. The Message Center? I will pass on that one. My PC-based voicemail system has been operating without the slightest problem for five years now. It has not lost a single message. I can use it to screen calls, page me, and do a number of other useful functions. There is no monthly charge (and it has long since paid for itself). Fortunately, my principles and practicality converge on this matter. I am antagonistic toward The Message Center in principle since it is the flagship example of a telco using ratepayer dollars to subsidize a competitive service to the detriment of the other players and ultimately the public.

The PacBell CLASS ads are somewhat misleading in a number of ways. Their promotion of priority ringing strongly implies that it's the person calling you who triggers the "special" ring, not that it will only work if they are calling from the officially entered number -- not from anywhere else (such as the proverbial payphone). No mention is made of limits to the length of the number list either. In most cases, for the purposes that PacBell is promoting this "service," conventional "distinctive" ringing, where the different rings are based on the number the callee dialed (and so will work regardless of where they are calling from) is much more versatile in practice. Distinctive ringing has been available from GTE Calif. for a long time (under the name "Smart Ring"). The PacBell promotion of Repeat Dialing is also misleading in a way that might be considered minor, but certainly gives a false impression. A busy woman gets the triple ring indicating a repeat dialing "completion" and immediately goes over, picks up the phone, and says "oh hi ..." As we know, that's not the way it really works. After she picked up the phone, the switch would *then* attempt to complete the call, and assuming it went through, she'd have to wait for ringing and answer of the other party; she couldn't just start talking. And while the ads say "available in the 213, 310, 818 area codes," implying that you have to be in those areas to subscribe to the services, they don't explain that any calls from outside those codes cannot make use of those CLASS features, nor could calls to/from non-PacBell numbers (of major significance in areas like L.A. where GTE has a *very* large base of subscribers intertwined all around and through PacBell areas. Neither company seems to be very interested in inter-company SS7 hookups. All in all, these CLASS features seem to be another attempt at getting money for semi-useless frills while the quality of "Plain Old Telephone Service" (POTS) goes down the tubes while the rates go through the roof. --Lauren-- ------------------------------ From: rm55+@pitt.edu (Rudolph T Maceyko) Subject: Re: AT&T EasyReach Problems in Rochester, NY Date: 12 Aug 92 20:29:21 GMT Organization: University of Pittsburgh I have an AT&T EasyReach number and recently moved.

In a few weeks, when they are finally able to make the change, they will coordinate a time with me to make the change over the phone, at which time they will give me a NEW MASTER PIN, which they say MUST change.

Organization: The World Public Access UNIX, Brookline, MA Date: Wed, 12 Aug 1992 21:23:45 GMT I finally talked to someone at MCI who apparently knew what they were talking about. A few notes from that conversation: 1) The calls originated from a prison. According to the investigative unit at MCI, this is pretty common. 2) MCI can't start calling all the numbers on a bill because it would construe harassment. They said that it would be extremely unlikely that I'd get in any trouble for doing it myself. 3) MCI requires a credit card and a SSN before opening a calling card account. No credit card was requested in this case, and the SSN was bogus. No surprise there. 4) The "I lost my card" call apparently was placed before they send out the original card, so only one card was ever sent out, which explains why I only received one, the replacement. I originally believed that the first card had been intercepted. 5) They also advised me to check to see if my LD carrier had been changed. It hadn't. 6) Case basically closed.

We used to have to call collect to a pre-arranged person who would refuse charges and request the number so the fictitious party could allegedly call back. Now-adays, why not just call someone with caller ID and get the number that way? Keep in mind that not all pay phones are set up to receive incoming calls. I would test it before waiting for that 'important' call-back. As far as I know, there is no other way to get a number of the pay phone.

I believe there is a Bellcore recommendation that 958 be used for this purpose, so it may work elsewhere. Note that many public and semi-public phones are set up to not accept incoming calls.

Okay, I'd be glad to, but I need a little more specificity before I launch into a long-winded exposition. Are you referring to CDMA in general (any form of Code Division Multiple Access) such as that used by the military, or are you specifically referring to the CDMA that the CTIA/TIA are working on for mobile phones?

Here on campus, I've called an answering machine before, and then hung up. The phone rings and the answering machine is still on the other end. I think I narrowed it down to the way that I hung up the phone. If I flashed hook (my hook is in the handset) and then hung up the phone, it would call me back. Otherwise it hung up just fine. Flashing the hook before hanging it up makes the switch think I'm placing the answer machine on hold and making a second call.

This is assuming I can't use a regular modular plug. Many hotels have standard modular jacks, but they often do various tricks to make them unable to disconnect, apparently to avoid having the sets ripped off. Sometimes they cut off the plastic latch lever, making it a bit more difficult to remove. Other times they have these funky screwed-on plastic blocks up tight against the lever. I can almost always get these off within a few seconds. (Once I pulled the cable out of the modular plug. Since I carry an el-cheapo Radio Shark modular tool in the bag of tricks, I reterminated it, sans plastic widget.) I've even seen the modular plugs glued in place. This is a bit much. I have thought of (and tried) using it on pay phones, but I've never found one where I could loosen the mouthpiece cover. I don't know if they use some kind of a special locking screw-on cover, they just screw them on >>VERY<< tight, or they glue them on. In any case, I have never found one that screws off by hand.

If the problem you're experiencing is solely (or primarily) the quality of the microphone, consider making the recording in a better quality recorder. If your machine uses normal cassettes, use your stereo system or ghetto blaster; if you have smaller tapes, buy or borrow a Radio Shack mini-recorder. When we purchased our first "celebrity impersonator" answering machine tape, we didn't like the quality after playing it into the recorder, so we just dubbed it onto the OGM tape and voila` -- much better sound.

For instance, California is installing a lot of roadside emergency telephones. My guess is that these are cellular, solar powered, programmed to dial only a certain number. I know on our large campus there has been discussion of using cellular for emergency phones in places where it would cost a lot to run wire. haynes@cats.ucsc.edu haynes@cats.bitnet ------------------------------ Date: Wed, 12 Aug 1992 09:56:16 -0600 From: rickie@trickie.uucp (Richard Nash) Subject: Re: Solve Three Problems (was Telecom Fraud) > In article phaedrus@cs.washington.edu > (Mark Phaedrus) writes: > Secondly, I had a question about how local phone company cards are > supposed to work around the country.

The mag stripe reader uses a different method of validating the card number than the manual punch-in method. In one system, the mag-stripe phone will automatically place a call to a calling card database validation centre from where your call is then completed (if card validates ok). As this system is telco dependant, surprisingly, it may not have access to the almost completely North-American wide, SS7 accessed, telco interworking Calling Card Service! Therefore, this may explain why your card did not work. The mag stripe system does not know about your card!

Anyway while I was there I noticed GTE had pulled all of > their customer service operations out of Clay County. This is standard GTE practice: centralize everything regardless of its impact on customer service, public relations, or even profitability. After all, if you need more money, just raise rates. GTE already has substantially higher rates in California than Pac*Bell for a significantly reduced level of service, so it is certainly possible to con a PUC into going along. My "desert hideaway" is served by Contel. Nearby is a small building that houses a remote from the main switch many miles away. On the front of the building are the block letters, C-O-N-T-E-L. Recently, the 'C' had fallen off and we had just assumed that it would remain missing until GTE took over and pulled the rest of them off. But yesterday it was noticed that the 'C' had been restored. So apparently the "absorption" of Contel by GTE here in California is not just around the corner. That is good since we are prepared to pull up stakes and move the operation elsewhere. Unfortunately, we require a level of service at the facility that GTE could never provide in its wildest dreams. > Another GTE story, told to me recently by a OSP contractor who got his > start as a GTE lineman in KY: Aparentaly GTE got a rate increase based > on some new services to be offered as part of a REA sponsered upgrade. This is another standard GTE sleaze: "provide" some insignificant, useless "improvement" to service (such as having business offices open until 8 PM on Thursdays) and then use that as justification to jack up rates. Understand that Contel already charges "higher than normal" rates in California because it operates almost exclusively in rural locales. Regulations allow telcos providing such service to compensate for the higher costs of providing service in sparcely populated districts. This is, of course, in addition to the ultra-cheap REA loans that Contel, GTE, and other rural telcos are entitled to. (A recent TV news magazine called this practice into question, claiming that the need for such assistance was long past.) In any event, GTE almost always demands a rate increase in any telco it takes over. The claim is that it provides a higher level of service (absolute balogna) and requires compensation for equipment upgrading. Contel in California (and I assume in other states) is a progressive operation that uses the most modern equipment and provides impeccable service to which GTE's brand cannot even be compared. IMHO, when GTE finally rips the Contel name off the buildings and tears them down, it should be required to lower rates by a substantial amount, reflecting the reduced level of service that will inevitably be provided. > Anyway GTE didn't get the loan and thus was going to be making too > much money. GTE always makes too much money. Well, at least it charges too much. What happens after that is anyone's guess. John Higdon | P. O.

This is accomplished through Centralized Equal Access. Telcos in Minnesota got together and built a fiber optic network connecting all their exchanges to DMS 100/200 to act as a Centralized Equal Access switch(es). This centralized location happens to have POPs for most carriers. In effect, each access line in the participating exchanges have a choice of carriers that have POPs at the centralized location. This idea was first implemented in Iowa in 1986, and went on-line in 1988. Today 128 independant telcos in Iowa partcipate in the Iowa equal access network (formally called Iowa Network Services) serving just under 200,000 access lines. This service is only available to rural areas (non-RBOC regions). Extensive modification to the DMS 100/200 software had to be made to provide dual PICs. Each number can be PICed for both inter- and intraLATA. Since INS domain covers five latas and three area codes, INS became an IXC as well. INS keeps a mirror of traffic on the netowrk. Telcos are technically capable of recording most toll (1+, 0+, 0-), but they cannot record 10xxx. the DMS 100/200 is surperior to most telco switches, and therefore capable of ticketing/recording all types of traffic, including 10xxx and FGB. The only problem I found with this setup is that the IXCs do not provide ANI if a call originates outside of CEA network to be delived in a CEA town. INS is capable of providing Rating and Recording for all partcipating telcos, CABS traffic reporting, 900, CMDS/STARS, Terminating Intralata Reports, and many other services. most of the participating telcos have dial up capability to change PICs. They dial up the VAX system, change the PICs in the database. The VAX changes the PIC on the switch in real-time through a direct serial connection to the switch. So lines can be connected/disconnected/PICed in seconds. MEANS is a mirror-image of INS, so the same goes for them. > I've noticed this in a few other cities, where an independent telco > will have their offices close to (or even next door to) a Bell > building, but in most such cases the independent serves the town, > leaving one to wonder what the Bell building is doing there!

When MEANS came on line, many telcos ran their own fiber optic lines from the local exchanges directly to the centralized equal access switch, therefore bypassing the Bells. Some telcos opted to use the Bells lines on a limited basis for the purpose of connecting their exchanges to the nearest fiber optic link to MEANS (thereby paying CABS charges to Bells). Today many of the Bell offices are abandoned because of the centralized equal access netowrk.

Let's not confuse a 5E in the AT&T network and a 5E in a BOC network, they are two different animals. The AT&T 5Es (as far as ER700 is concerned) are operating as OSPS switches, the 5Es in the BOC networks are usually configured as local, CO switches. This is a very important point! (Also, AT&T updates their 5E's with each release of 5E software, while outside companies have to pay for this priviledge! Quite often, they cannot make a business case for the new features in each release of the software and therefore do not purchase them.) How Rochester Telephone is connected to AT&T is the real question here, NOT how their 5Es are configured, what switch they are running etc. That is something Rochester Tel will have to answer. Posting this information would be great. The bottom line is: AT&T is not trying (legitimately or illegitimately) to get rid of concerns regarding their service. We have made every effort to satisfy our customers, just sometimes these glitches raise their ugly heads. > I am generally quite happy with AT&T EasyReach ... it is an > exceptional service.

To directly answer your question: Radio Shack makes an outdoor ringer, an electro-mechanical bell that appears (from my catalog listing) to be line-powered. See catalog No. 43-174, price was $29.95; it may have gone up, but also might be on sale. It's not terribly ugly if you want to install it indoors. Similar ringers are often found at home remodeling supply stores (e.g. Builder's Square, Handy Andy, HomeBase, etc.). HOWEVER, a loud ringer that your relative can hear may simultaneously scare the daylights out of any visitors in the area. I suggest you leave the standard ringers in place, and consider "Fone-Flashers" instead. These are also made by Radio Shack, and flash lights or strobes instead when the phone rings. The standard Fone-Flasher (43-177; $14.95) has an AC outlet into which you plug a lamp or similar device up to 300W. The Fone-Flasher 2 has a built-in strobe and ringer (43-178; $29.95). There is also a Mini Fone-Flasher (43-179; $8.95), which is line-powered and flashes an amber light. All prices are as of 1989, unfortunately; must get a new catalog sometime. :-) Disclaimer: I have no connection with Radio Shack. Andrew C. Green Datalogics, Inc. Internet: acg@dlogics.com 441 W.

All this mag stripe stuff seems overly complex to me. I've often thought we could do this more simply with bar codes. Just print the bar code on a clear card. Use an opto interrputer module to read the card as the person slides it between the LED and the opto detector. I have not experimented with this. There may be a problem with LED spot size requiring rather large bars, but it does seem that something like this could be done. Much simpler than reading off a magnetic head, and it's permanent. Do credit cards need read/write memory, or is ROM sufficient?

The 'reason' that eel-skin wallets wipe mag stripe cards is that they very often have magnetic catches on them. I was told that this is due to their low inherent strength -- i.e. a conventional press-stud catch tends to rip the leather.

It seems that Hagfish skins are sometimes used to make eelskin wallets ...

Most of the Panasonics, especially the models from the mid 80's, have very pleasing sound on the OGM's. With the newer models using 'standard' (as opposed to 'loop') cassettes, one can improve this quality by recording the OGM on a standard cassette recorder with a good quality microphone, then leaving a second or two of silence to trigger the tone and the switch-over to record mode. I use a cheap Panasonic 1458 (about $60.00) and it does a great job.

The condenser > mics in most machines sound tinny, and pick up motor noise. What I've found works really well with most answering machines is calling in and changing the message via the remote control options. That way, you have a regular-sounding voice, instead of the speakerphone-in-a-cave effect that you get when using the built-in mic. Of course, this is most convenient when you have more than one line, but if you don't change your message too often, it works well even to call from somewhere else to change the OGM.

PAT] Your original note did not make it clear that you had ordered an off-premise extension. As noted in my original post, this is a way to have this service accomplished. What I was noting in the paragraph above was that we have, in exceptional circumstances such as the loss of business on PBX trunks, performed direct half-taps in the CO on the old and new cable pairs. This is usually done over as limited time period as possible, perhaps eight hours as a guideline, and only after the half-tap has proved usable. Off-premise extensions and/or answering service bridges are usually done with equipment allowing the bridge legs to be isolated, typically bridge lifters.

Perhaps this is an obvious solution, but could someone in telco land explain how both numbers would call the other one, (vice-versa), without the other one being automatically called also?

PAT] As others have said, this is not as simple as an extension circuit. The impedance of the unused pair will bridge the used pair and cause significant distortion in transmission and signalling. In the case of the answering service the loops are supplied with bridge lifters. These are high value loding coils which are easily saturated. When a user goes off hook on one of the pairs, the lifter on that pair is saturated and its impedance will collapse. The lifter on the other pair remains unsaturated and its high impedance prevents it from affecting the performance of the other loop. The original questioner could not get service at two distant locations because the telco would not put lifters on his circuit. i.sinature ------------------------------ Subject: How to Trigger a Pager From a Modem From: jholmes@mcb.com (jim holmes) Date: Thu, 13 Aug 92 20:19:41 EDT Organization: Message Center pfalstad@phoenix.princeton.edu (Paul Falstad) writes: > Hi!

This allows you to send alphanumeric messages to someone's alphanumeric pager, provided you have the proper phone number and the PIN number of the desired party.

The protocol for this is the IXO/TAP protocol, and some source code I wrote for dealing with it is in the Telecom archives. The short answer: IF YOUR PAGING VENDOR HAS NOT DISABLED THIS FEATURE: Enter just the letter "M", then a carriage return. This signals the paging system that this is a manual entry. It will then prompt you for the pager id and the message. Cybertel, our paging vendor, has threatened to turn this feature off because they claim it ties up the modems for too long, while people dither over what text message to send. If your paging vendor does not support manual mode, then at the ID= prompt, you send followed by a logon ID, followed by . I gather that the common default is PG1; I've also heard of PG, PG0 (zero), and PG0000 (four zeros). They will either send you back or , depending on whether or not it's a valid logon ID. Then comes the tricky part. You send them a pre-formatted message packet. The content of the message packet is: PagerIDMessagechecksum PagerID is all-numeric, eight digits or less, and some systems require it to be left-padded with zeros to eight digits. Message is any string of up to 120 characters (on some systems, up to 240). Checksum is a three-byte hexadecimal representation of the numeric checksum of everything from to , inclusive, with A=":", B=";", C="<", D="=", E=">", and F="?". (In other words, the next six ASCII characters after "9".) After you send this packet, you'll get back either ACK or NAK. The paging software can send back lengthy comments or error text any time it likes, but you're pretty much supposed to ignore everything but the ACK or NAK. If I get a NAK, what I do is look through everything from when I sent my packet to when they quieted down for any line ending in that is over 5 characters, and assume that that's the error message to show the user. The most common two are, of course, invalid pager id and bad checksum. Oh yeah, and any time they're going to hang up on you, they're supposed to send first. One annoying feature of Cybertel's system is that they do NOT an alphanumeric message sent to a numeric-only pager. This is a horrible over-simplification of a complex protocol that also permits multiple packets to the same address, and messages to multiple pagers in the same session. You really should consult the IXO/TAP spec. The only problem is, the only way I know to get a copy is to buy a GlenAyre or similar paging system yourself; it only seems to come with the manual. Maybe your paging company can provide you with a photocopy, otherwise, good luck. J.

According to Bellcore's "CLASS(SM) Feature: Automatic Recall" document, TR-TSY-000227, Issue 1, Sept. 1988, Appendix E, Section E.3, "Update Requirements": The subscriber's incoming memory slot should be updated for each incoming call that does not receive busy, call forwarding, or Selective Call Rejection treatment. ... The incoming memory slot should always be updated for all incoming calls that are call waited, whether or not the incoming call is answered by the called party." -------- In general, if you can answer a call, the memory slot will be updated. Of course, whether the "call waited" caller has a number to put in the slot is a function of SS7 connectivity, etc. Calls from MF trunks, "multi-party" lines and Operators will update the slot with an "out-of-area/DN-unavailable" indication. Whether a particular vendor or TELCO elects to follow the TR is another issue.

To be honest, that depends on the kind of telephone switch your telephone is on AND on the kind of facilities (CCS 7 or not?) the call-waiting call came in. The Bellcore TR that describes the call-processing feature you use when you dial *69 specifies that you should ring back the person calling on your call waiting call, if possible (i.e. if the call came in on a "smart" facility (CCS7/ISUP) so that your switch knows the phone number to call back). The feature is known as "Automatic Recall", "Automatic Callback", or "Call Return", depending on which organization you talk to. As far as I know, if your phone is on a Northern Telecom DMS-100 switch, this interaction will work. I know that because I coded about half of the software for this feature in 1988 (I worked at Bell-Northern Research at the time). The person who designed the Call Waiting/Automatic Recall interaction was a good friend of mine (her name is Heather Sinnott). But I do not know where in the world she is now, or where the other designers are. I am still amazed at the power of Usenet today.

I said I didn't know, so he went to three-way calling and tried them.

PAT] They break the dialtone on a 1A ESS; I will have to try them on some other types. They does not seem to be accepted as "dialed digits". They might be useful as some sort of special control signals for something like 710, but the requirement of special hardware, like ABCD, would preclude the use of the service from "normal" phones that litter the land by the millions.

Since one of the telephones in my house has ABCD, I've been able to use them to pound on everything in sight. My dial tone comes from a 1AESS (213-930). ABCD tones do not break the dialtone but they do reset the timer that kills your dialtone after 20 seconds of not dialing anything, so if you want to hold a dialing circuit indefinately, you could send "A" every 15 seconds. Other than that, they seem to have no affect at all on the CO. I can insert ABCD tones between a valid dialing sequence with no effect. Inside my CLASS features, they don't seem to do anything except restart the instructions that the system is currently reciting. I couldn't get them to do anything interesting (like getting it to recite a "PRIVATE" entry in my lists"). ABCD did break dialtone on the GTECA DMS100 I was on when I lived in Venice Beach (310-452) but I couldn't get anything except "call cannot be completed as dialed" messages. As far as voice mail systems go, I couldn't get mine to accept ABCD as part of the password. Usually ABCD tones would just restart whatever I was doing. I've tried them on Octel's ASPEN (via L.A.

I tried playing the D tone continuously into the phone after dialing 15551212. I'm not sure, but I believed it knocked the DA operator off the line and gave me my dialtone back.

I erroneously thought that the loud bells had been defenestrated from the RS catalogue, but it turned out my own catalogue had had that page mangled and folded under. My error. Interestingly, most Radio Shack stores used to carry that item in stock, but at least around here the several stores I frequent seem not to keep it out on the shelf. That contributed to my belief that it had been dropped. I received several mentions of Hello Direct, apparently a well-known firm but unfamiliar to me. Others talked of contacting support organizations for the hearing impaired, and others mentioned the devices that flash lights or strobes in response to detecting ring. Several folks suggested plugging obnoxiously loud things like blenders into such a device! There were other references to firms marketing ringers for such locations as factory floors and for farms. I ended up purchasing an old, pre-breakup Bell external ring unit from a gentleman who had it just gathering dust in the garage. It arrived yesterday, and seems quite (but not EXCRUTIATINGLY) loud.

Radio Shack used to sell a device that would flash a table light when the phone rang. Basically, you would plug it into to the phone and inbetween power and the light, when the phone rang the light would flash. I have no idea if they still sell them however. Considering as we all pay an FCC surcharge in order to help people with hearing difficulties I suspect you may have some good luck calling your local phone company and see what they can do for you.

DTMF "A" breaks dial tone, but otherwise appears to be completely ignored no matter where it is used. DTMF "B", "C", and "D" all cause an immediate error if you dial them as the first digit; if you dial them after a "9", they cause an error (alternating high/low pitch tones) when you finish with all the digits. I don't even have an outside line here to try it direct to the CO.

Are you sure it wasn't: "Priority Ringing(SM) - another new idea ..." ? {Priority Ringing(SM) is a Service Mark of Pacific Telesis} You see, you can offer a known product as a "service", give it a new MARKETING NAME, and claim/register it as your own. In fact, there are many lawyers making a good living off of the courts and this little gimick -- they register lots of names and acronyms as theirs, and then sell you the right to use them (because you won't find any desirable one's left). Another method of decreasing our national productivity ... Anyway, if they marketed it as "Distinctive Ringing", they'd have to say (somewhere): "Distinctive Ringing(SM) - a CLASS(SM) offering from ..." {Distinctive Ringing and CLASS are Service Marks of Bell Communication Research(CO), Inc., a research unit of Pacific Bell(CO), which is a subsidiary (for a while) of Pacific Telesis(CO).

Interestingly enough, Illinois Bell doesn't use the word CLASS, but names (without SM, TM, or CO symbols) the CLASS services the same way Bellcore names them, except for "Repeat Dialing."
