First I talked to the data communications guy I knew from previous visits, but after a few tricky questions on availability of Caller ID, Call Return etc, he forwarded me to the exchange hardware supervisor. I talked with him for quite a while and the following came up: the city digital exchange is quite ready for Caller ID (he actually had a phone with the display on his desk), but the private telcos are afraid to implement stuff like this for fear of legal problems. Also, seems that the telcos follow the lead of the Helsinki area telco, and in that area there are lots of people who are stickier about their privacy than "normal" subscribers. Then there's the fact that special services like this have here traditionally been billed for activation, not pay-as-you-use which of course limits the amount of consumers who are interested enough to get these services. While I was there, I got the date for the next stock- holders meeting. I'm going be there, let's see if I can't raise some dust! -- * * * Otto J.

Why is this solution not sufficient? On major point that seems to be CONSTANTLY overlooked here is a psychological one. I for one wsould not purchase a feature such as Call Trace or Call Block until I need it. At the present time I haven't needed such an animal for several years. Now paying several bucks a month for a feature I might possibly need once every four or five years does not sound too cost effective. As a consequence the probabilty of any significant fraction of the telephone customer base having this feature is insignificant in the extreme. A harrasing caller would be well assure that his chances of hitting someone, first shot, who already has this feature is somewhat less likely than being hit by a meteor. Now the telco could offer these features for free and install it on everyone's phone ready to use when the need arises, but I fear we have just left the realm of the unlikely and entered the realm of the unreal. Many people (I for one) will purchase Calling Line ID in a heart beat! Now the probablity of stumbling upon someone with this feature suddenly becomes much more significant. Now there exists a distinct possiblity of getting caught in the act ON THE FIRST CALL! Recently, in the metro Atlanta area, an obsence phone caller harrased over 100 women. He called them up on the phone, claiming to have kidnaped their husband or other member of their family, coerced personal information from them, and then proceeded to try to get them to perform various sexual acts that may be best left unsaid. While many did not comply, some did follow some of his instructions, and most were terrorized in the extreme. Now picture this situation. Say 10% of the customers in this area had this feature (high yes, but maybe not, if it becomes real popular). He would have had ten or more women with his phone number reporting him to the police! Now, you say, what if he was calling from a pay phone? Well, now you have some track of his where- abouts and his activities. The police might even scare up a witness or two. With this possiblity, is the risk worth the thrill? The damage he did was considerable and both physical as well as psychological. These women were literally raped over the phone!! Are the people opposed to this feature recommending we all get these protective features and feed the telco coffers just in case of something like this or do they prefer to let someone like this get away with his obsence perversion and let these women fend for themselves?? This guy was not some off-the-street creep. His methods were well thought out, involved superficially personal information, and was extermely convincing. He played on many peoples darkest fears and convinced many extermely intelligent women that their husband or children really were in danger if they did not act out his fantasies! All of this was reported in the Atlanta Constitution that reported most of the victims were in the Gwinnett County area, a generally affluent suburban county where a significant number of individuals could be expected to purchase a fancy new toy like CLID. The reason the harrassing phone calls have gone down in New Jersey is the active risk of somebody having this feature just because they like it, not because they got it for protection! This guy never called anyone back twice. A feature which you don't have and takes a month to get is totally useless against a random caller like this. The key here is not that you can report his number to the telco or the police. The key here is that the risk of getting caught is high enough to discourage this kind of crime in the first place. It's true that even if you have CLID and you have a harrasing caller, you still have to storm the barracades down at the telco bureacracy. It hasn't bought you anything over the other features, if you have them. It's the RISK! It's the PREVENTION! It's raising the probability that a given "mark" already has the feature installed! Are you, in your thin defense of your precious privacy while invading mine, condoning the activities of these perverted individuals. Condoning it or not, you seem to be supporting their cause quite well! --- Michael H.

In other words, the little box would read out, "Dr. Brown at home" > or "Smith Telemarketing Co." etc...the same purpose would be served. PT] I have numerous objections to this: - I suspect at least 10% of the households will have a member highly insulted to be identified as *Mr.* when they are *Mrs.* or vice versa, or to be identified as their child or parent. This alone will generate enough bad feeling and charges of sexism to make it a bad idea. The phone company needs to promote separate lines for husbands and wives and have the idea well-accepted before trying this. - It greatly confuses the distinction between telephone numbers and names. Many people will think that the phone company is doing something it can't do - identify which person is using the phone (by fingerprints?). The technically uninformed may be even more unwilling to call "hot lines" even if the hot lines don't have Caller-ID and say so. We have a voice mail system at work which does identify the caller or callee by name or both to the receptionist (inside lines only - outside lines are identified by some code meaning "outside line" and maybe identifying which outside line) when the call gets forwarded or busy/na-forwarded. Somehow, the line/name association is programmed into the system. Voice mail users and the receptionist can get confused with the two-people-sharing-one-line problem. I'm not sure how this can be handled other than one person doesn't get call-answering messages taken, and the other gets messages for both. The person who doesn't get call-answering messages taken probably never bothers to check voice mail. - Use of this information by a customer service department is likely to screw up the already blurred distinction between the Visa cards of Mr. Smith, his father, and his adult son, all at the same address. - Names are not unique. I don't want my calls blocked just because some jerk with my name sells swampland out of his home. - I don't want to block calls from Charles M. Sanchez's medical office just because Charles M. Sanchez's kids make nuisance calls from his home. - A company name alone isn't enough. For example, "Radio Shack" identifies at least dozens of entirely separate locations with thousands of phones in my area code, plus the warehouses, factories, and corporate headquarters. (some of these have PBX's, but they do not share them between locations.) - I wouldn't want to block all calls from a company I do business with just because their fax machine keeps calling my voice number. The phone company will not know which lines are fax lines. But it would still be nice to block the fax calls until I can get the correct fax number onto lists in each of too many departments. - When I was at RPI, I had to have a call traced. Phone company records identified the caller as a pay phone at 110 Eighth Street, and they couldn't give any more specific information. Further examination of phone company records would have revealed enough pay phones at 110 Eighth Street to make a mile-high tower of them on top of the administration building, to say nothing of the non-pay phones. A large area around that had no phones at all (according to the records, which obviously had the billing address). (They finally gave me the NUMBER. It took about 5 minutes to identify it with a campus directory.) Does this mean I would have a choice of blocking both the alumni association and pay phones in the dorms, or neither (assuming I was still in the same area code)? - Caller-ID should provide a "handle" that can be used to identify a line to services like Call Block, Distinctive Ring, etc., so suggestions that Caller-ID display names but Call Block accept numbers only destroy much of the usefulness of having both.

In other words, follow the person's name with the letters "ems" in parentheses. The person's name is really not used, but is useful for user-friendly purposes. 3) MCI Mail will notice the "(ems)" and prompt you for an External Mail System (EMS). At the "EMS:" prompt, type "internet". There are other networks you can use here, by the way -- type "HELP EMS" to find out what they are. 4) Next, MCI Mail will prompt you for the mailbox. At the "MBX:" prompt, type in the Internet address. I.e. "ejs@goldhill.com". 5) MCI Mail will then ask you to verify the address name and then will continue with further "TO:" prompts. 6) You can use the same process for the "CC:" prompts. 7) Everything else is as usual. -- Eric (0003962594@mcimail.com) [ugh!] ------------------------------ From: Subject: Re: Internet Gateways to Commercial Networks Reply-To: Organization: University of California, Berkeley Date: Wed, 6 Sep 89 00:17:12 GMT In article langz@asylum.UUCP (Lang Zerner) writes: >[Moderator's Note: They are getting easier to use all the time.

As for AT&T, MCI and Compuserve, maybe someone from >those places reading the Digest can send along the methodology involved >in getting mail to the Internet. PT] In MCI Mail, at the "Command:" prompt, type "CR" (for create letter). At the "To:" prompt, type the name of the person you are sending to, followed by "(EMS)" (with the paretheses (sp?)), like so: To: Joe Blow (ems) Then, it will ask for the EMS system, type "Internet", like so: EMS: Internet Then, it will ask for the MBX (mailbox) of the person, you type the internet address at this point: MBX: ranma@cup.portal.com MCI Mail does NOT have a smart mailer. So, if you mail to UUCP, Bitnet, etc, you have to use the gateways to get there, like so: MBX: bougus!address!ranma@uunet.uu.net MBX: ranma%address.UUCP@uunet.uu.net (this assumes the machine "address" is in the published UUCP maps). MCI Mail polls NRI (their mail gateway) every 30 minutes. In MCI Mail, you can send to a person by their name, but that is an interactive session where if there was more than one match, you get to pick the right person on MCI Mail. Mail from the Internet, you can't do that, so you must know the MCI Mailbox number of that person. The MCI Mail recepient does not see the Internet routing headers when they recieve mail. The Internet mail can be directly "REplied" to in MCI Mail. Your Internet address can be part of a "list" on someones MCI Mail acct (alaiases). MCI Mail will send a message to the originator (on MCI Mail) if the message has not been delivered (because of TCP foul-ups, host down, etc.) It will keep trying for 3 days, the it will return the message as undeliverable. On Lotus Express, when you create a letter, at the To: prompt, hit "F9" to expand the address, the fill the "EMS" and "MBX" prompts like usual. Hope this helps.

Sending mail from MCI Mail to the Internet works the same way as from MCI mail to any other network to which they have a gateway. You give the "EMS" option after the recipient's address, then the network name "Internet" and for the mailbox address, the Internet address of the recipient. The gateway is very well implemented and does a good job of preserving mail addresses so you can respond to them smoothly. When sending into MCI Mail, the mailbox number is written with no punctuation, so my address there is 0001037498@mci.com. I have seen no documentation for this gateway, but since at the moment messages pass both ways for free (not even the usual MCI Mail message charge) I can hardly complain. >From Compuserve, you give an address like ">INTERNET: user@site.domain" on the address line.

When I use to work at MCI, we had a list of the so-called CNA bureaus that we would call when we needed to look up the name of a disputed number, and NYNEX was right in there. We would call them up, and after giving them a number (I.D. number, no doubt), we would give them the telephone number in question. Pac Bell is the same way. In the area of security, in MCI, their customer system was called OCIS (pronounced "oh-sis"), for On-line Customer Information System. It ran (runs) on multiple IBM 3070's running VMS, in a CICS appication (it uses DB-2 for the database). The thing I seem to remember is that they were lax as far as what you can get from OCIS. Almost everybody could get the full billing information on you (from anywhere in the country, the country is divided up into 7 divisions, and you'd have to "access" each division to find somebody, but that just takes a few more keystrokes). The only thing they placed restrictions on was who could view Calling Card codes and who could do changes to that account. They just now got on-line call-detail, and the call detail is held on-line for 3 months before it is archived. That is how I found an ex-girlfriend (and saw who she was calling to boot). We had fun looking up celebrities and other people we knew to see who they were calling (get the numbers, call the appropriate CNA, then volia, "We Got Your Number!") It was a great way to kill time, needless to say. Needless to say also, I don't work at MCI anymore, that's why I'm telling you all this.

Green" Subject: Re: Radio Station Names (Wxxx - Kxxx) It used to be that the FCC was Very Particular about how a station identified itself: the "official" ID had to run within 2 or 3 (I can't remember) minutes of the top of the hour. An official ID consisted of the Call Letters followed immediately by the city of license. And they meant "immediately": "WABC, New York" was legal; "WABC in New York" was not. If an AM and FM station shared the same call sign, that needed to be included as well: "WCBS-FM, New York". The FCC is a *little* more lax now - the hourly ID only needs to run once per hour; it doesn't matter when. Another factor in how the stations ID themselves is how the ratings service credit the stations for listeners. Used to be that the station only got credit for a listener if the listener listed the FCC call sign in the listener log. Now, I believe that the stations get credit for Easy-101, Hot Hits 98, TalkRadio 77, etc. etc. Stations would much rather build their identity thru a logo-trademark kind of thing (even if it is franchised or purchased from a Format Company), than a sterile set of 4 letters, so you will often find, on these heavily formatted stations, that the "legal" ID is buried in the middle of a jingle touting their logo. -scott ------------------------------ Date: Tue, 5 Sep 89 13:17:33 PDT From: "Daniel M.

I'm pretty sure that stations can call themselves anything they want most of the time, except for their top-of-the-hour legal ID. Every station *has* to give a legal ID at the top of the hour, and that is (invariably, I think) the call letters and transmitter location. For instance, K-ROCK in New York (an offshoot of Infinity Broadcasting's KROQ in Los Angeles, I believe) calls itself K-ROCK over and over again. "92.3 K-ROCK," "K-ROCK New York." But, at the top of the hour (+/- 5 minutes) they always say, somewhat sheepishly, "This is W-X-R-K, New York." At our radio station, I can -- and frequently do -- call it anything I want for station ID's. "This is Postmodern 90.1" or "You're attuned to FM 90.1, Stanford University."

Aircraft radios are licensed by the FCC, and pilots have to get a "Restricted Radiotelephone Operator Permit" (at least that's what mine says) in order to operate it. As a call sign, one uses the FAA-registered aircraft identification number. All US-registered civilian aircraft have aircraft identification numbers that start with "N." (Oh, I just lied a bit; Airlines get to identify themselves to ATC via radio using their flight numbers, regardless of their aircraft ID number, e.g., "Richmond Approach, this is US Air 1462, 32 miles southwest, ...."

It seems to me that when advertising money gets tight, businesses are going to fall back to the book issued by the local telco. Distribution is bound to be more extensive, and customers who really want the yellow pages call the telco, not "Sorta Yellow Publishing". Come to think of it, I haven't received any unsolicited "alternate yellow pages" lately. In Boston, at least until recently, individual orders for phone books were filled through contractors. A guy in an unmarked white van drove around dropping sets in accordance with a worksheet. An order I placed last month, however, was delivered by the mailman. If the contractor arrangement is used for general distribution, I could easily imagine crews trying to unload as many books at a given place as they can.

I'm in a Chicago suburb. When I recently added another phone line, I was asked what directories I wanted. I said I had a set and didn't need any more. Brrrt- Sorry, that's not an option! So I got a regional (this 'burb and surrounding communities) directory and yellow pages combined. Also I asked for a Chicago directory (those are not normally distributed outside the city) and a 'B' and 'C' Chicago yellow pages. One is "Business-to-Business" and the other one is for "normal" use. Again, we normally don't get those. Inside the city, I believe that residential subscribers normally get only the "regular" one and business customers get both yellow pages. Since I was curious, too, I asked the phone company about other areas' phone books. You can get any phone book you want for free, but if it's for some weird place, I get the idea that they'd kinda like an explanation. (Heh Heh Heh, put him on the racks!). When I moved in my old condo, there was a phone book left there from the North Pole and surrounding areas. Wasn't too big... Anyway, before I chucked it, I did verify that Santa Claus was listed. And no, I didn't call and also forgot to write down the number. 2) Fascination with numbers. When I was a lot younger, I used to be very interested in the "special" numbers used by the phone co. for whatever reason. Most have changed, I suppose. Here's a list of what I still have (remember this is in the Chicago area). xxx-9996: 1000 Hz Tone (most exchanges). My notes also say "try -9949 and 9940". 796-9600: Name/Address Locator Service. I suppose that most people know about this one. They answer the phone "what number?", you say a phone number, and they give the subscriber's name and address unless, of course, it's unpublished. I needed this service once in another city, and was told here to ask Directory Assistance there for the "Name/Address Locator Service", but the remote DA never heard of such a service, so maybe it's only local. There used to be a phone number that you could call to get the phone number you're calling from, but that's long since changed, and I don't have the new one. I'm told that they change it every few months. If anyone has more info on that, I'd like to know. It used to be VERY handy to find out the phone number for your company modems when the DYMO label fell off and you needed to call the thing. So now, instead, we have rack-mounts in the computer room, and while there's numbers on the jacks, going from the rack to the jack you have to pass through this massive throbbing pile of wire ("Yep, Harry went near there last week and fell in. Haven't seen him since.")

If you're doing business, you can apply for a business radio license and find some frequencies to use in the 30-50 range as well as 150-174, 450-470 and up. (All these numbers are megahertz.) You can also contact a communications reseller and rent both radios and space on a "community repeater" which will provide more reliable communications. If you're not a skilled radio hacker, this is a good bet since you'll have a communications solution tailored by professionals to your needs. Make sure you shop around as both quality of service and price will vary greatly. If you just want to talk to your wife, cellular or old style mobile telephone will do the trick and will be cheaper. Amateur radio is a complex means to an end. If you're not interested in the code and tech stuff, it's lots of work to gain access to a very limited subset of the spectrum. And both you and the party you're communicating with need to be licensed. Also, you're not allowed to do "business". > 2) The common CB connection.

By 'new telecom' I assume you mean an electronic key telephone attached to a business type telephone switching system (a PBX or Key System). > Can anyone suggest a reason for this problem and a possible >solution. Any suggestions are welcome. If my assumptions are correct the problem could be power related. Electronic telephones generally derive their power (for their basic functions anyway) from the lines. Usually the phone has two pairs of wires feeding it; one pair that carries the audio and one which carries the 'data' signalling to run the set. The power (probably -24 volts) is across the pairs. There is no potential between wires in a pair, but between a wire from the voice pair and a wire from the data pair you should be able to measure a voltage (24V). You may have a problem in the modem that is affecting this power transmission. One thing that comes to mind is 'A & A1 control'. This is something that most Hayes compatibles do if you turn it on, and it simply provides a short on the second pair to signal a key telephone system whenever the modem is off hook. Another thing that would cause a problem is the disconnection of the set (the one plugged into the modem) when the modem is in use. This happens on some modems.

At that time digital transmission facilities were just being introduced. They could connect two central offices, up to 25 miles apart, over existing exchange cables. Today we have fiber to the home and the beginnings of a true broadband interoffice network. What might tomorrow bring? If, for the moment, we leave the *all import issue* of network management aside, imagine what the home of the near future might be like. Think of communications and information services as a commodity that draws a close parallel to the present electrical distribution plant. No one tells a toaster what to do, the function is built into the appliance. Will we have 1.5, 45, and 500 megabit service runing to our homes and business to match our requirements? Several outlets in each room for connection? One bill per month for cable TV, phone, FAX, security,... the list goes on. Pay for the bandwidth you use and decide for yourself what appliances to buy. Of course many large users approach this capability today, but it will soon spread to us little people. Telecommuting may yet become common, and other opportunities appear endless. Find a vendor with a service you want and arrange for access. If this seems like a pipe dream, check out some of the field trials that are going on today. It never ceases to amaze me what we take for granted today, that was considered impossible yesterday. Enjoy the discussion :-} and turn the "gee wizz kids" loose on the applications.

Some of my postings may have gotten waylaid on their way to Telecom Digest (I'm not on this net) so you may not have seen this: Beginning on 9 July 1988, calls between *most* Northern Virginia exchanges and *most* Prince William County exchanges were changed from being Toll Calls to being "Extended Area Calls." [If you want the list of affected Rate Areas, I can probably provide it.] To explain in detail: I believe that "Northern Virginia" means "any exchange in Virginia, whether controlled by Contel or by C&P, which is a local call from Washington, DC." "Prince William County" means "any exchange in Virginia, controlled by Contel, which is inside ('associated with') the Washington LATA and which is not already included in the definition of 'Northern Virginia' above." This includes all of Prince William County plus a small part of Loudoun County (Arcola exchange) and maybe a small part of Stafford County (Stafford exchange). In Virginia, you have the option of ordering six different levels of local phone service, some of which charge for local calls by time of day, distance and time spent talking. Charging this way for Local Calls is called Local Measured Service. "Extended Area" means a special type of Local Call which is ALWAYS billed at Local Measured Service Rates regardless of the type of local calling plan your phone has. From C&P PAY PHONES, Extended Area calls are a flat 25 cents no matter how long you talk, just like all Local Calls are. In most of Virginia, Extended Area Calls are dialed with just seven digits, even if they cross an Area Code boundary. Presumably, this is done to fix the thought in the minds of subscribers that "this is not going to be charged at Long Distance Rates." Indeed, Extended Area Rates are about 80% lower than Intrastate, Intra-LATA Toll Rates for the same distance. This dialing rule cannot apply in the Northern Virginia/Prince William case. Here's why: As Central Office Codes were given out over the years, it was assumed that Prince William would always be a Toll Call from Northern Virginia. So, prefixes which duplicated those used in the Washington Metropolitan portion of Suburban Maryland were allowed to be used in Prince William (and vice versa) since different dialing procedures would apply when calling those two places (Prince William and Maryland) from Northern Virginia. Calling Metro Maryland would be 7 digits. Calling Prince William would be 10 digits (now 11 digits since 1987). Once Extended Area Calling arrived, it was logical to reduce the dialing in both directions between Northern Virginia and Prince William from 11 to 7 digits. This was done in the Prince William to Northern Virginia direction. But it could not be done in the opposite direction due to the code duplications that had been implemented over the years. The then- (and now-) in-effect Washington Metro dialing rule that "all calls between Met exchanges are 7 digits" required that 7 digit dialing to Maryland remain. Therefore, Extended Area Calls from Northern Virginia to Prince William had to remain at 11 digits, even though they were now a form of Local Call. Therefore, there *are* cases besides the Bowie-Glenn Dale foreign exchanges you mention where Local Calls within the same Area Code are now 11 digits. It was done for the same reason in both cases. These, too, should logically be reduced to 7 digits after a suitable waiting period after 7-digit interstate dialing ends. >Your announcement of 1 Oct. 1990 is the first time I have heard a date for >that change. I got that from two sources, the front page of the Washington Post (sometime in May 89) and also from the Arlington (Virginia) Journal. The Journal's version of the story also noted that 10 digit dialing for Local Calls across the Area Code boundaries would become *optional* on 1 January 1990 and *mandatory* on 1 October 1990. Currently, dialing these at 10 digits is *impossible* (blocked by "cannot complete as dialed" recording). >I previously asked in this Digest: Does that mean that Md. & Va. suburbs are >being removed from area code 202? Yes. I cannot think of any way in which prefixes could be duplicated in two Area Codes where those calling from outside the region could dial either Area Code and still get routed correctly. The 202 mapping will have to end. Example: My home phone is in 703-979, also reachable as 202-979. Once a REAL 202-979 prefix is assigned - the whole purpose of this exercise is to allow that - then one would be connected to the new 202-979 when dialing 202-979 and could no longer reach me that way. You could, of course, still reach me by dialing 703-979. Businesses that have cheated for years by painting Area Code 202 on the sides of their trucks when they're really served by 301 or 703 prefixes are going to have to re-paint. Ditto for those who have *no* Area Code in their advertising. That's their problem. By the way, only the Washington Metropolitan portions of 301 and 703 are mapped into Area Code 202. Exchanges slightly further out which are still local to DC but Toll to the far side of 202, were apparently never mapped into 202 and are not reachable that way. There's an element of logic in that since it distinguishes "Washington Metropolitan" from "all other." >(I know there are points elsewhere in Md. where local calls to another area >are available by dialing 7D only. I am not as familiar with area 703 in this >regard.) I think there are several areas, also well outside Washington, but in 703, where local calls to another Area Code are 7 digits. There are a few near Winchester that are local to an exchange in Area 304 in West Virginia. ADDENDUM: By the way, for purposes of determining Local and Extended Calling Areas, Area Code 202 is divided into two Rate Areas: The smaller one is called "Pentagon, Department of Defense." Everything else in 202 is called "Washington." The reason for the splitup: Pentagon prefixes, although in 202, are physically located in Virginia. Pentagon numbers are NOT also mapped into Area Code 703. (In fact, one of the Pentagon prefixes, 202-694, is duplicated as 703-694 in Stuart, a small town in outstate Virginia.) Calls from Washington to Prince William County are Toll. Calls from Pentagon to Prince William County are Extended Area, and are currently dialed with 11 digits. They may change to 10 digits when the dust settles. Calls from Prince William to Pentagon are also Extended Area. I have seen no definitive literature on how those calls are dialed. The general Contel brochure which accompanied the 1988 change said that one would no longer have to dial 1 + 703 for these calls, ignoring the fact that the Pentagon is in 202. I *think* that these calls are now 7 digits, but will change to 10 (not 11) digits after 1 October 1990. Sorry for the delay in replying. I received your 16 August posting on 5 September.

Here's a UK view of charging for DA calls. Over here in the UK British Telecom (BT) has unsuccessfully tried to introduce charges for directory enquiry calls a few times over the last 5 or so years. The main reason that the attempts have failed is that BT only provide a phone directory book for your local area. If I have the name and address of a company in London but no phone number I will phone 192 and expect to be given the number without charge. This is the attitude of most of the people in the UK, that is why BT have been defeat on the charges for 192. Now if people were to be given a terminal linked into the whole of the UK directory enquiries database (as the French have for their database) or we were given all the UK phone books by default ( :-) then people would not mind paying for 192. The fact is that as we do not have the information provided for us by default so we expect to be given it without charge. Most people over here usually complain that BT is being immoral (yep, that's the word they use) when they try charging for 192 as there is no other source for the information 192 provides. Now, I think there is a case for charging for local directory enquires as it usually means that I am too lazy to get off my ar*e and find the phone book, though there should be a method for the operator to cancel the charge if the number I am looking for has changed/been added since the last printing of the phone directory book. 192 calls from coin boxes should still be free as the yobs have normally torn up the phone directory books to use as bog roll. We can but dream. +--------------------------------------------+--------------------------------+ | K.Hopkins%cs.nott.ac.uk@nsfnet-relay.ac.uk | Kevin Hopkins, | | or ..!mcvax!ukc!nott-cs!K.Hopkins | Department of Computer Science,| | or in the UK: K.Hopkins@uk.ac.nott.cs | University of Nottingham, | | CHAT-LINE: +44 602 484848 x 3815 | Nottingham, ENGLAND, NG7 2RD | +--------------------------------------------+--------------------------------+ ------------------------------ Subject: Help, Weird Equipment Required!

Nope, this is not for illegal purposes, nor is it for telemarketing, an activity that *ought* to be illegal... At night, certain phone lines are supposed to be forwarded to *recordings*. This device would be used to check these lines to see if the lines are properly forwarded (ANSWER) or if someone forgot (NO ANSWER) or if we need to try again later (BUSY). Since this would happen at night, there's going to be nobody around to do the test, just a lonely computer. I'm not a telephone person, and have no idea of what kind of gear is out there. Do you know who has such stuff, so I could call them, or of any way I could find out who has equipment like this? Would a telemarketing equipment supplier have stuff like this?

Partee. The agreement, filed with the Illinois Commerce Commission, calls for Centel's 134,000 Illinois customers to receive a $4 - $6 credit as a refund. Customers will save an estimated 40 cents per month from the permanent rate reduction. Partee had threatened to file suit against Centel because the telco had failed to pass along savings they realized under the Tax Reform Act of 1986, which reduced the corporate income tax from 46 percent to 34 percent. Centel serves customers in Park Ridge and Des Plaines, IL, two northwest suburbs of Chicago. In addition, they serve a small number of customers in a little section of the northwest side of Chicago. The refund and lower rate will commence upon being programmed into the computer, and will be retroactive to September 1, 1989.

He sent a picture of the telephone receptacle and plug, it looks just like an RJ11 plug and receptacle to me. Does anyone know whether the Japanese commonly use RJ11? Does anyone know what kind of power is typically provided at "wall outlets", i.e. what voltage and frequency, and what a "Japanese" style power plug looks like?.

For the purposes I will discuss below, showing the caller name would be preferable (and also solve the unlisted number issue, but not the necessarily the crank call problem.) My last name is not particularly suited for voice telephone transmission and human speech recognition. (My German way of pronouncing my German name does not help, I admit.) In other words, each time I ask for info, place an order or whatever, I end up spelling my name at least twice and still get amazing permutations on the mail that follows.

This has not been established; I wouldn't put this in such rhetorical terms! I personally don't mind the idea of a code, but if the telephone number of the initiator of a harassing caller ever flashed on my box, you can bet I'd call them back pronto and return the favor. I think having the full phone number of the caller, even though it is unlisted, would be preferable to just a code, but either way, there are ways around whatever comes to pass, and your reasons for wanting a code are not really effective, nor completely fair -- read on. > One of the features of the calling party id device is the ability for *you* > to screen your incoming calls and stop people from harassing you. This can > be done by simply blocking their code/phone number. This can also be done by giving *them* a few calls back. How many folks do you think would harass you if you harassed them right back? Not that I would play telephone tag with some jerk I don't know, but it seems reasonable that being able to call people back after they harass you on the phone is a fairly effective method for dealing with the situation. There have been testimonials from people in this forum who have this service and have already used it to put a quick stop to harassing calls simply by calling harassers back. And what if you run out of storage in your blocked number list? All the descriptions of the number blocking service have included limits to the list of numbers that can be blocked. If you are ever so fortunate to be on just one telemarketing list, or to have a credit card, you can be sure that your blocked list will grow right quick. ``So call the telemarketers back and ask them to stop calling you,'' you might say. RIGHT. Ever try to tell a computer you don't have dialup access to to forget about your record in their database? I wouldn't believe any telephone marketing organization would remove my record from their files when I asked unless I could be allowed to remove it myself. > Must I give up my right to have an unlisted phone number just because > someone wants to be able to return a harassing phone call? Read ``must I give up my rights so someone else can have theirs?'' Well, as someone else was mentioning last week, yes and no. Rights are only just if they don't infringe upon those of others. It seems we have that case here, and it's a hard problem to solve. I tend to think that if those with unlisted numbers truly want to have privacy, they should not call anyone. After all, if they don't want anyone to bother them, why should they be able to bother others? Right now, if someone calls you and wakes you up at 4 am, you have no recourse, and cannot return the favor. With CID/non-pub, you remain anonymous inasmuch as you cannot be called back if you should harass anyone else. Why should you have that privilege while the vast majority of callers are held directly and immediately accountable for their calls since their numbers are listed? I think that the rights of those with unlisted numbers are being carried out such that they will be conceptually immune from any identification system, and everyone *else*'s rights to immediately know who is *invading THEIR privacy* are sacrificed. Unless every participant in the telephone network is treated the same, the CID system cannot be truly fair to all, listed and unlisted ALIKE, as it should be. If someone with an unlisted number wanted to remain anonymous (or at least not directly reachable) in the midst of CID, with codes or no codes, one could certainly do so with other methods. One could establish a line for making calls, one that is listed, but is perhaps never answered, or put your modem on this line. Modem carriers are never very exciting. Another separate line could be unlisted, and used only for receiving calls from those to whom I give the number, or for making calls to the same. I realize that adding an extra line may seem a bit excessive of a step to achieve the privacy that CID seems to be reworking, but if you really value your privacy, you sometimes need to take steps to insure it. Being the exception to the rule often involves a price, which is not unreasonable, in my mind, at all. Inconvenience in the interest of fairness for ALL is sometimes the price you have to pay for your own liberty. > Returning an obscene or harassing phone call can only escalate the problem > further. Not according to the testimonials here. As I mentioned above, those who have this service have demonstrated that they can put a quick stop to the harassment by calling the person back and giving them some harassment they can understand. If you have evidence that calling the person back only escalates the problem further, let's see it! > After all, does anyone really believe that they have the right to know my > salary, how old I am, what religion I practice, what color I am, or what my > phone number is just because I called them on the phone. I think not.

Actually, no. Access to "your" unlisted (unpublished) phone number is something which the telco agrees to not provide in certain circumstances -- published paper directories (with a reasonable likelihood to also include "Electronic White Pages" -- machine-readable or online directories -- if and when telcos get around to providing them) and Directory Assistance.

Here at Bellcore we have some experimental service trials, one of which is Caller Name Delivery. (Don't have the CPE for it, so we've got a bit of a hack with a DecTalk board -- you pick up the phone, and it says "Call from so-and-so", then you press * to accept the call or hang up to reject it.) The problem is administering the database. You'd like to meet the emerging performance expectations from Calling Number Delivery -- deliver the name between the first and second rings. That means you have to have accessed the appropriate database and found the name before the first ring is finished. If you try to do it from the terminating end, you've got to find a database on the originating end, send back a query, and get a response, all in (probably) under 1-2 seconds. Not easy. If you do the database lookup on the originating end -- makes more sense, because that's where the information is -- you've got to send the information along with the call setup information. There's no place to put it in SS7 basic call setup, so you've got to either hack it in somewhere in SCCP (Signaling Connection Control Part) or go back to standards and modify the protocol. Also not fun. (In the experiment at Bellcore, it's simple -- if the call isn't from a station subtending the Red Bank CO, we don't get the caller name...) In other words, a very good idea, and probably one which is a desirable solution, but a bear to make work. -- David G Lewis ...!bellcore!nvuxr!deej "If this is paradise, I wish I had a lawnmower." ------------------------------ End of TELECOM Digest V9 #356 *****************************   Date: Thu, 7 Sep 89 1:14:35 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: Duplicate Mailing Message-ID: <8909070114.aa03125@delta.eecs.nwu.edu> Issue 355 got mailed twice by accident....numbered the second time as 356 in the header, but in fact 355 in the text.

Most people would probably choose to have suppressed-origin calls ignored by their phone (with a recording back to the caller that suppressed-number calls are not accepted), and most businesses and government agencies would still accept them (maybe government agencies should be required to accept them, since callers are not potential profit-generating customers).

Speaking of rumors, a few years ago there was a major rumor (even saw light of day in the newspaper) that Pac*Bell was buying out GTE's Los Gatos operations. You should have seen the smiling faces in Los Gatos, not the least of which belonged to members of the Town Council. To my knowledge, the Los Gatos Town Council is the only governing body to have passed a resolution declaring that they wished they had a different telephone company serving their town! Now that's not a rumor; that really happened! You see, when the EAX crashed for two days, it put their fire and police out of business, since both are "served" out of that office.

In the old days, you used to be able to get phone books for distant places for free, not so anymore. It used to be that you could call up the phone company in a given area and order a "state set."

That would accomplish two things, it would totally eliminate any chance of you being bothered by ^JUNK CALLS^ and second (and of far greater value to the free world) it would eliminate another irrational, isolationist, closed minded voice trying to freeze progress (and far trade) because it is i n c o n v e n i e n t !

These include 621,261,858 (prefixes which use 1-301-569-xxxx for local call to 301-569). I believe 621,261,858 had 1+7D (now 1+301+7D) instead of 301+7D dialing to long-distance points within Md. Arcola, Va. (Loudoun County) is 703-327. As of now, Herndon (Va.) has 7D local calls to there AND to DC, and 301-327 is in Baltimore city, so there is no 327 in DC or Md. suburbs (the 10D local calls across NPA boundaries will make 327 available in DC). Stafford, Va. is 703-659. I know of 301-659 in Baltimore city. 659 COULD occur in DC (I don't have prefix list with me as I write this). So when Md. and Va. suburbs are removed from area code 202, you will (as is the case with an area code split) be shrinking an existing area code. However, you are not creating a new area code. I believe a way to summarize these changes is that the new 10-digit local calling scheme affects those points within the DC calling area. (Note that I did not have the info about Pentagon <--> Prince William being extended-area local when I came up with that idea.) As far as I know, if you are in Md. and local to Va. (or vice versa), you are also local to DC. (Speaking of the Pentagon: it was written a while back in this Digest that pay phones in it are in the Arlington, Va. exchange; however, I don't know if they are in the Rosslyn-area exchanges or in the Crystal City & National Airport area exchanges.) By the way, time of day is set up as a local call throughout Maryland. Prior to these DC-area changes (i.e. now) you dial 844-1212 to get Baltimore time of day, unless you are in the DC calling area, in which case you dial 844-2525 to get Washington time of day. ------------------------------ End of TELECOM Digest V9 #357 *****************************   Date: Fri, 8 Sep 89 1:21:28 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #358 Message-ID: <8909080121.aa11390@delta.eecs.nwu.edu> TELECOM Digest Fri, 8 Sep 89 01:20:14 CDT Volume 9 : Issue 358 Today's Topics: Moderator: Patrick Townson NTIS Telecommunications (Thomas Lapp) Charge Tables for British Telecom (John Pettitt) Voice Mail or 2nd Phone Line?

The tables below contain the current (effective september 1989) charge tables for British Telecom. Charges is the UK are based on `units'. A unit costs 4.4 pence (5.06 including 15% tax). That's 7 and 8.09 cents respectivly at USD 1.60 to the Pound Sterling. All UK calls have supervision and one unit is billed for each unit of time or partial unit of time between answer and hangup. No credit for partial units. Time allowed in seconds for each dialled call unit fee of 4.4p (5.06p inc VAT).

There is also a sister publication (PH3826) "Your Guide to Apparatus Rental Charges". The book also goes on to detail example calls of 1 thru 5 mins at each rate and gives the international charge bands Having at last got a list of BT charges I would be very interested to compare this to the post-deregulation US. I suspect that we are being charged rather more. On another subject, does anybody know how the choice of LD carrier for the US domestic part of international call is made ? BT have been known to use both MCI and AT&T (I have had error recordings from both). Do they use an others ? Is it some clever least cost system or is it just a % split.

Date: Thu, 07 Sep 89 08:28:23 -0400 Hi folks... I'd like your opinions regarding my future telecom needs for my home (apartment). Right now, I have one residence line and a DID voice mail number. The voice mail service i am using now is cheap, but has been losing important messages for me due to busy signals. I'm trying to decide whether to go with a commercial voice mail/pager service or a second phone line with answering machine. The commercial service allows me 150 calls per month (.20 each beyond 150), and a pager to indicate when i receive a voice message. I would forward to voice mail when I am on a modem or other long phone call. (I HATE CALL WAITING!). This service would cost me about $25 per month. My other option is to get a second phone line with minimal outdial service, and an answering machine. The phone line would be $60 to install, $10 a month for service. I'm wondering about answering machine cost -- and whether there are answering machines which provide full access from a remote touchtone phone. Any recommendations re machines like this would be appreciated, as well. The cost of my two options seems to be similar -- if I amortize all the costs over a year or two (as long as I'm likely to live there)... the second phone line can come in very handy sometimes... but the voicemail/pager also comes in very handy as well... which should I go for? -- Steve Elias -- eli@chipcom.com (for Chipcom / networking related mail) -- eli@spdcc.com (for metroboston email2fax and personal mail) -- voice mail: 617 859 1389 (send email to both addresses if you like) -- work phone: 617 890 6844 ------------------------------ From: Jeffrey Silber Subject: MEGACOM Anyone?

So a Piper Warrior N1234A identifies himself as Cherokee-1234Alpha. The controller has the option of calling the aircraft Cherokee-34-Alpha, after which the pilot may shorten the call to the same abbreviation. Most helicopters are called Helicopter 1234A, no matter the brand. Special function aircraft are sometimes referred to by that function. I.e. Traffic-watch-1234-Alpha. This makes sense, since it allows all and sundry to know what's going on. (Traffic watch aircraft fly low and slow and do lots of turns over the freeway on final approach to the airport yesterday at 5 O'clock in hazy condition, where the heck is he??? But I digress. :-) Helicopters do the damnedest things. If you have a bunch of aircraft, you can apply (to the FAA, I think) to use a special callsign, like Academy 21. When you go outside the local area though, you revert to normal aircraft ID's like Cessna 5678Alpha.

Most railroads in North America use frequencies around 160-161 -- VHF high band, and can be picked up on scanner receivers, if you know the right frequencies.

(RS-232 >line driver / receiver chips. Also known by other numbers.) Ah! One of my favorite subjects: Lightning Damage. Strange and awesome stuff, lightning. I am a telephone engineer with about 20 years of experience with telecommunications and datacom equipment. I will share a few practical suggestions with you. If you want the textbook and/or technical explainations, go read the many books on the subject... then learn the hard way anyway! :-) >Plugging devices into orange outlets helps. :-) >It helps even more if the ground (green) from these outlets is tied back >to a central point and earth grounded there. (No connect to box/conduit) > >It would seem to me that this would only provide a superior return path >for the induced charge in the data line to return to ground. Although it is an unsafe practice (not to mention contrary to UL and Nation Electrical Code) I have found situations where the only cure was no grounding at all! Not recommended, though. Yes, isolated (orange) outlets are a little helpful. Mostly they help with line noise, not lightning induced transients. Use a good surge supressor on your power, too. My personal favorites: Transtector for best at any price. Trippe-lite for cost effective use. We put Trippe-Lite IB-20's on every telephone system we install. Note: Do not be decieved into thinking a UPS solves powerline transient problems. Get info from Oneac or Best (UPS mfr's) on this if you need more info. We use Tripp-Lite OMNI 450 or 1200's for cost effective UPS w/regulation & surge suppression. They are perhaps not the best on the market, but they work quite well for us. >Question: Are we dealing with a magnetically induced current, or a capacitive, >static pickup of some kind. All of the above, plus more. Most damage is from EMF induced transient voltage spikes, but a nearby strike can do unbelievable damage. A direct strike... What do you think 200,000 volts can do? The idea is to make a more attractive path to ground for the induced transients than through the equipment. There's more, but I only have 20 minutes for this discussion... >Using shielded data cables will ward off evil charges/inducements. >Well, charges maby, but inducements, I don't think so. If so, what >do you do with the shield, besides connecting to pin 1 at each end >and probably just generating a ground loop current, and about half >the equip. I work with doesn't even have pin 1 connected. First, do not connect pin one at each end. Since pin one is your frame ground, connecting the equipment together makes the cable a path for transients. We usually ground the main cpu/hub very carefully (an 8 AWG solid wire, run directly to the entrance water pipe, no bends or corners, as short and straight as possible and connected to a bus where all the shields connect.) All equipment located at the main cpu is directly grounded to this bus. Orange outlets are used and the feeding electric panel is confirmed to be double grounded: to the water pipe and a ground stake (at least 5' from the foundation and 10' long) per National Electrical Code. This is as close to ideal as possible without violating code. What about pin seven? Well... we have been known -not- to carry though pin seven either. I know this is not receommended, but the isolation and removal of ground loops often justifies this - if the data will still pass. (I said practical, not textbook) I still prefer braided shield (and not the 70% stuff, either) but foil shield is often a necessary evil. Twisted pairs are advantageous if used properly. >Placing expensive ($50 each end) protection devices at each end will >neutralize evil. DO THESE WORK? What are they? Ferite Beads, cap, diac, MOV? >If they are necessary why not put the magic circuit on the Terminal or >the CPU (Computone?) driver/receiver circuits. Here's a useful circuit: put 50 ohm resistors (1/2 or 1/4 watt) in series with each RS-232 lead as it comes out of the system/terminal. Put a 24 volt MOV (or, butter yet, a Tranzorb) on the lead with the other side to ground on the opposite side of the resistor form the system/terminal you are trying to protect. The resistor isolates the equipment and helps make the MOV appear to be a more attractive path to ground. This method solves most problems for us. This can also be used for phone line protection, but use 150 volt MOV at the highest wattage you can find and use 1 watt resistors and have the phone company install a Three Element Gas Tube Protector on the incoming cable (Bell often uses two Two Element units - not the same) Be sure the phone company grounds the daylights out of the protector AND DOES NOT USE YOUR GROUND WIRE! >Socket all the '88 & '89 devices, like WYSE does on their WY-60 terminal, >but not yet the WY-995 mux board.

I'm just curious. The International Telecommunications Union allocates prefix codes for radio transmitters. The United States is pretty fastidious about assigning such "call letters" to every sort of service, including broadcasters. In other parts of the world, broadcasters may simply use names (i.e., "Orwell Radio" in Ipswich, UK) or non-ITU call signs (the ones beginning with "2" in Oz; "2" is assigned to the UK.) But some services, such as Amateur Radio and aviation (the same prefix codes are used for airplane registration), strictly follow ITU allocations. You can find a complete list in a number of Amateur Radio publications, such as the ARRL Logbook and the Callbooks. ITU prefices are allocated in three-character blocks, although usually only the first one or two characters is significant. For example, W, K, and N are entirely USA, so N-anything is USA, but AA-AL are USA while AMA-AZZ are shared among various countries (such as Pakistan AP and Argentina AZ). Italy owns the entire "I" range. France owns all of F, the UK owns "G", "M", "2" (2AA-2ZZ) and much of "V" (for overseas posessions). The USSR owns "U", "R" and a bunch of smaller blocks. There are three patterns for the first two digits. The oldest are letter-letter (AA-ZZ). After WWII they added number-letter (i.e., 4X and 4Z for Israel, 9Y for Trinidad, 3DA-3DM for Swaziland and 3DN-3DZ for Fiji -- that's the only case where the third character counts!). Eventually those ran out so they use letter-number (i.e., J3 for Grenada, Y2-Y9 for East Germany, Z2 for Zimbabwe). Note that letter-number is only possible when the first letter is not entirely owned by one country. Thus W, K, R, G, I, etc. can't be the first of a letter-number, but A, C, and D can. How countries make use of these is up to them. Canada uses Cxxx for broadcast, but VE for most Amateur. Sometimes amateurs use special event prefixes, just for fun, so we have to look on the master list to see what country it is. fred ------------------------------ Date: Thu Sep 7 23:25:09 1989 From: Vance Shipley Subject: Re: Help, Weird Equipment Required!

It seems to me that what you really need is to ensure that the forwarding gets done to begin with. If you cannot ensure that someone will do it what you need is either a flexible 'night service' feature from your pbx or a 'network management' system for same. The night sevice feature would be the best way to go, as long as the time of day is correct (in the switch) it would be done without fail. If this isn't possible then a network management system that was compatible with your pbx (or centrex) could be used to alter the configuration on a schedule.

I've figured out that FGX > is, I'm pretty sure, Feature Group X, but can somebody tell me what those > feature groups mean? Feature Group (whatever) are various kinds of Interexchange Carrier access arrangements. To quote from my favorite source, "Notes on the BOC Intra-LATA Networks"... (from this day forward to be referred to as "Notes"): Feature Group A: Line-side originating and terminating LATA access for which an originating subscriber dials an assigned telephone number that connects to a specific IC. The IC returns a tone to signal the caller to input additional tone-generated digits of the dialed number. [In English: The IC has a box with a bunch of subscriber lines at each Point of Termination. You call this box to get access to the IC network.] Feature Group B: Trunk-side originating and terminating LATA access for which an originating subscriber dials 950-WXXX, (where W = 0,1 and XXX is the Carrier Access Code), which is translated to a specified XXX carrier trunk group. Optional rotary dial service and ANI may be available. [In English: The IC has a box with a dedicated trunk group at each PoT. You dial 950-WXXX and the switch translates this to the appropriate trunk group, giving you access to the IC network. Used where/when the switch hardware/software is/was unable to provide 10XXX translation.] Feature Group C: Trunk side LATA access for AT&T Communications, generally, on a direct basis between each EO and an AT&T switching system. [Replaced by FGD in most places; I honestly don't know how it worked or what the details of it were.] Feature Group D: Also referred to as "Equal Access", Feature Group D is trunk-side LATA access affording call supervision to an IC, a uniform access code (10XXX), optional calling-party identification, recording of access-charge billing details, and presubscription to a customer-specified IC. [In English: Presubscription or 10XXX dialing.] > For example, we've got an AT&T System 25 PBX (or is > PBX an outdated term?).

US West said that the CENTREX service was the ONLY was to get _hard hold_ ( to engage hold: flash and hit *9, hang-up. The phone will start ringing after a few seconds, so one can walk to another phone and resume the conversation by just going off hook again ). This feature is NOT available is part of the the regular residential feature group that US West markets as TeleChoice. ( like features are cheaper when purchased under the TeleChoice plan than under the CENTREX ). I am sure there is no difference at the CO, just the marketing and tariffs, etc. I really enjoy having both the three-way calling and the hold, but the charges are a little steep, I think. After all, my service is measured and if I originate both sides of a three-way call, I get charged double the rate for the duration of the call. In reply to Patrick's comments a few weeks back on whether it was better to have special equipment on site or pay the local OC for various services, for the long term it sure seems better from my point of view to go the buy route. My one Panasonic phone with built in hold works great. However, it would take awhile to pay back the purchase of several new phones with hold at the rate of $30 per year, ($2.50 for hold, for 12 months). One further comment, it seems that US West is behind most of the other LOC's in providing the newer features of CLASS and Touch*Star ( or whatever it is that Patrick keep talking about :-). US West just keeps pushing the old standard speed calling, call waiting, 3-way calling under a new marketing package. There was a news story I saw over a year ago where a US West spokes person was asked about the newer features such as caller ID, call block, call trace, selective forward and so on.

The carrier for the US domestic part of the international call will be the same carrier that brings the call across the Atlantic. In order for each carrier to provide international service (AT&T, MCI, etc.) that carrier has to reach an agreement with a carrier at the other end. AT&T, MCI, etc. have each reached agreements with BTI for bringing traffic into and out of the U.K. If BT chooses an MCI circuit for the transatlantic portion of the call, it will remain on MCI for the domestic portion. I suspect, but am not sure, that BT just uses a percentage split, where the percentage of outgoing traffic offered to each carrier is the same as the percentage of incoming traffic received from that carrier. /john [Moderator's Note: Do you know whether or not the British Telecom subscriber gets any choice in the matter? That is, can they indicate by any routing code, or by going through an operator that they wish the call to be routed over AT&T or over MCI? If a subscriber makes a collect call to the USA for example, does whoever pays for the call get to select the international carrier? Or are they stuck with whoever BT routes them on?

Initally, I didn't like it, but with a few modifications described below, I find it to be an indespensible tool. The first thing I noticed about the Liteset was the fact that I couldn't get the thing to stay in my ear comfortably. I went through all nine earpieces with marginal success. The cone type seemed to work ok, although it was a little uncomfortable. When using the Liteset, I was annoyed by the amount of background noise that the microphone picked up. Since the actual mike element is several inches from your mouth, they boost the gain to compensate. This also boosts the volume of any noise in the room. I haven't tried it, but I would imagine using one of these things in a computer room would be very annoying to the person on the other end. To compensate for the background noise problem, I took a 2" piece of insulation from a 50-pair phone cable and slipped it over the end of the microphone. This made the voice a little tinny, but cut down on the noise a great deal. I used it this way for a few more hours and still couldn't get used to something hanging free in my ear like that. So, I took the Liteset ear/mike assembly apart, desoldered the leads from the little circuit board inside, disassembled an old Plantronics Starset ear/mike assembly and soldered the wires to it. The various impedances matched pretty well. In fact, the Starset volume is actually higher than the Liteset. The microphone is crystal-clear and loud on the other end...plenty of gain to punch through a noisy long-distance phone call. Aside from the lousy ear/mike assembly that originally comes with the unit, it's a great cordless phone. The keypad dialing is nice, along with the mute button. An earlier posting mentioned the ability to listen to other cordless phones by disconnecting the power on the base unit while off-hook. A much more elegant way to do the same thing is to press and hold the mute button while powering up the cordless unit with the on/off switch. The base unit does not go off-hook, but the receiver in the cordless unit turns on, allowing you to listen to other phones on the channel. If anyone is interested in the details on how to modify the Liteset to use a Starset capsule, send me mail. I'll respond directly, and if there are enough inquiries I'll post to the net.

I have been viewing the discussion of caller id (CID) from the sidelines, since it is very doubtful that Pacific Bell will be offering CLASS features in the near future and I'm sure my prefix won't see it in this century (unless they figure out how to make it work in a 1ESS). But, after reading Mr. Warfield's somewhat lengthy article in favor of CID, and specifically having the number itself, not a code or name, show up in the display, I have come to the conclusion that I am against CID in general and Mr. Warfield's proposals in particular. That which knocked me off the fence was the passage quoted above. You bet I want to preserve my precious privacy. All of us have been fighting the erosion of that commodity all of our lives and the battle has been getting tougher and tougher. At this point, I make two assertions. The first is that the problem of crank calls has been overstated and the second is that there are ways of dealing with cranks that do not require the general populace to surrender another chunk of their privacy. I won't take the time here to list all the things one can do to discourage a crank caller, but even in the most extreme case, all one has to do is get a second line and unplug the phone from the first. Then your antagonist can ring it to his heart's content while you use your second, unpublished, line. While you are waiting for its installation, just hang up on your breather. He will get bored quickly. But why should we *all* have to give up our privacy? I don't make crank calls. I have a listed number, but I make all outgoing calls on an unlisted one. No one, and I mean no one, has that number. If it ever rings, I answer it "wrong number, please learn how to dial" and hang up. Why should I surrender that number to everyone that I call? And what good would it do them? If there will be such a thing as a "private" exemption, then what good will CID be in detering crank calls? Any crank caller with an IQ greater than a watermelon will have an unlisted number. And that, to me, is also giving more information than I wish to give. Most people don't know that I have a private line since they have my listed number. When I call them, instead of 723-1395 (calm down, it's in my .signature) showing up in the display, it will say *PRIVATE* or whatever. Cover blown! Whenever someone insists that innocent citizens have to give up something in the name of catching the guilty, the argument's over. If the catching of perpetrators infringes on the rights of non-perpetrators, then another method of catching perpetrators needs to be found. The other (fun) aspects of CID are interesting, and of course I would have it in an instant. But now we're back to academics, since it won't be offered in Perpetually Backward territory in the forseeable future. -- John Higdon | P. O.

I have heard some legal arguments involving freedom of speech that indicates that speech in an anonymous way is not protected. If courts accept that argument I would surely expect it could be extended to Caller ID. It just depends. When I worked at Ohio State, I received at my work phone literally HUNDREDS of phone calls for a "Dave Applegate". A variety of different voices made these calls, though I think there were some repeats. At first I told the callers that no such person works there, lives there, or has ever been known to be there. No such person was listed in the campus phone directory. The callers always hung up without saying anything. Soon I started just asking them who they were, but they hung up immediately. I was suspecting some telemarketers. Eventually, after about two years of this (yes, TWO YEARS averaging 1 every 2-3 days), I finally "trained" myself to make a totally different response: ****RING**** Me: I R C C Them: Dave Applegate, please Me: Could you hold please. (pause with handset mic covererd) Me: He's not in, right now, may I take a message? Them: No thank you. (They hung up) This repeated a few times, and I still wasn't finding out anything. So after a few more months I got even bolder: ****RING**** Me: I R C C Them: Dave Applegate, please Me: Speaking Them: Yes sir, I'm calling to let you know that your stock purchase has been completed and you may pick up the certificates at any time. Me: Thank you. (They hung up before I finished) After I did this, there were no more calls ever again. I suspect this was a drug shipment!! Any ideas? [Moderator's Note: I cannot see any reason at all to go back and hash over all the pros and cons of Caller ID again. If you want to know all the opinions on the subject, simply check out the last couple dozen or so issues of the Digest. If you don't have access to these, I'll try to select the ones which had Caller ID articles in them and sent them along to you. Seriously, I think Caller ID has been worked to death here in the past month. There is little more to say which has not already been said; and the messages are going now more in the direction of telephony only coincidental to politics rather than the other way around. I will print whatever messages are left in the queue on this subject, then let's find something new to cuss and discuss. The next time an *original* post comes in on Caller ID, someone kick me if I print it and invite such a barrage of "re: mail" again. It should be obvious by now no one solution will work for everyone. It should also be obvious by now that this issue has sharply divided many people in the industry itself. Consider how many rebuttals and counter-rebuttals have been printed in our little Digest alone. You'd think that people would realize the telcos have never sold *privacy* as part of the deal. They sold only communication links, and the fact that until recently the caller's identity was hard for the telco to ascertain is not a valid reason to insist on the same 'privacy' now. The basis for the industry is communications between people; not the privacy rights of either, one it gets past the directory non-pub stage. Don't everyone send this chap copies of the last two dozen Digests at one time and cause his mailer to break or something. I'll select them if he can't do it himself.

I certainly agree with Bernard Mckeever - a SxS CO would be a great place to visit. Unfortunately, SxS offices are becoming a thing of the past, and are non-existent in many areas - even if you could manage to find a "cooperative" telephone company employee. Some of what I am about comment on will be lost on many people, but it should bring a real smile to those readers who have had any firsthand experience in an SxS CO. > If your lucky enough to go through at night when the traffic is > light, you can hear calls as they proceed from line finder to > selectors to connectors. One of the best trouble shooting tools > of the stepper switchman is a good ear. When an SxS office is relatively quiet, a good ear can really be a useful diagnostic tool. A few examples: 1. A faulty selector, trunk or open wire in a Tip-Ring-Sleeve triple will cause the switch train to abruptly collapse and immediately seize the next available linefinder-first selector, all occurring with a rather characteristic sound. 2. A faulty preference chain circuit in a linefinder frame, or a fault in a subscriber line/cutoff relay circuit will cause the linefinders in a given linefinder frame to "thrash" wildly with a truly unforgettable sound. 3. A group of outgoing trunks that are out of service, say due to a carrier system failure will result in an ATB (All Trunks Busy) condition having a characteristic "BZZZZZT!" sound as a selector runs around into the 11th ATB position while trying to find an idle trunk. In those CO's equipped with ROTS (Rotary Out Trunk Switch), the same sound, but slightly different, will emanate as the 22-position ROTS step switch runs around like a ferris wheel trying to find an idle trunk. > It also helps to have good eye sight, SXS offices tend to be very dark. An abyssmal job is fixing a bank multiple wiring problem, while sandwiched between the bank wiring sides of two adjacent rows of switch frames. It's cramped and dark, with the primary illumination coming from a portable 48-volt spotlight. And just when you found the problem, you pull the spotlight cord too far and an alligator clip comes off the battery cord, plunging the work area into twilight again. :-) > Today most remaining SXS offices have evolved far enough to > provide Touchtone service, and use digital transmission systems > for interoffice communications. During the early 1960's the Bell System developed grandiose plans for conversion of SxS CO's to permit offering DTMF service. The basic scheme involved placing a simple trunk circuit between each linefinder and its associated first selector. When this trunk circuit detected a service request from a linefinder it would signal a simple arbitration circuit (I hesitate to use the term "marker") which would select an idle register-sender and connect it to the linefinder through a crossbar switch. The register-sender circuit would decode the DTMF tones using a receiver, store the decoded digits, and then outpulse them to the first selector. The register-sender would release and be available for another call upon decoding and outpulsing a predetermined number of digits, or upon a timeout. From a human factors standpoint converting SxS to DTMF presents a problem in that it is REALLY NO FASTER than rotary dialing. While a subscriber may lift their handset and DTMF-dial 7-digits in less than 2 seconds, they may have to wait for at least 7 seconds of *silence* while the DTMF digits are outpulsed as rotary digits. As public "demand" for DTMF service grew in the 1970's, most Bell System operating companies elected NOT to convert SxS offices for DTMF service, but to simply wait for eventual total replacement with 2ESS or 3ESS. The reasons for the lack of conversion effort were many, and included: (1) "poor" financial investment in already-obsolete apparatus; (2) less than optimal human factors acceptance; (3) lack of other features that the public was demanding which could NEVER be provided in a SxS CO, like call forwarding, call waiting, etc.; (4) desire to implement message unit timing for all subscribers, whose implementation through a CDA (Call Data Accumulator) was very expensive; etc. As a result, during the 1960's and 1970's comparatively few SxS CO's were ever converted to DTMF. While WECO had designed conversion apparatus, very little was manufactured, and the Bell System elected to do something which I always felt was unusual: they used conversion apparatus manufactured by ITT in many small SxS CO's. ITT makes pretty strange apparatus as compared to WECO, and I could never understand why the Bell System chose to give WECO installers and BOC switchmen the culture shock of dealing with this apparatus. The only Bell System SxS CO's that I have personally seen (during the late 1960's, early 1970's) converted to DTMF used the ITT "Tel-Touch" apparatus. The only WECO apparatus that I have personally seen for DTMF conversion in SxS used a clever, but bizarre scheme of "magnetic core logic" (really!), and was intended for conversion of 701-type SxS PBX's. The operation of this apparatus is similar to that described above, except that DTMF matrix-to-digit translation was performed using magnetic cores, and the digits to be outpulsed were stored in magnetic cores (really!). Such upgraded 701's, which were relatively few and usually a Centrex CU switch, represented a unique blend of SxS, crossbar, wire-spring relay, magnetic core logic and solid-state circuitry never again found anywhere else! It is more common to see independent operating telephone companies still running SxS apparatus that is converted to DTMF. The technology most common in this marketplace uses solid-state register-sender circuits which are dedicated to one linefider-first selector, thereby eliminating any need for crossbar switches or any common control apparatus. With today's integrated circuits, one can manufacture such a register-sender on a single printed circuit card for a cost of less than $ 35.00 - but 25 years ago such an attempt would have required at least six cubic feet of space PER CIRCUIT with an apparatus cost 100 times that amount! > Way back when, the only modern > features you could get with a stepper were number hunting, > [rotary or level] and toll diversion if you were in a PBX > selector group.

Adjusting relays using an assortment of bending tools, tension gages and a 35-type relay test set is an unforgettable skill - sort of like learning to ride a bicycle. Also like learning to ride a bicycle, one thoroughly screws up a lot of relays before learning the art. :-) Words alone cannot do justice to a 35-type test set. This test set, whose principal design evolved BEFORE 1920, has been virtually unchanged for almost 70 years - and is STILL IN USE TODAY. The 35-type test set has four miniature telegraph-style keys, plus 8 resistance sliders which move across a tubular ceramic resistance coil, and is used to set the various operate/non-operate/release current values for the windings on a relay. A SxS maintenance job that is the real pits was cleaning switch bank contacts using "circular" toothbrushes dipped in trichloroethylene; this was before the days when this solvent was recognized as hazardous, and extensive cleaning in a poorly-ventilated CO would result in the switchman getting a good "buzz" from the vapors. The most complex circuit I have ever seen in a "traditional" SxS CO was the SD-31592 Prepay Coin Control Trunk. Any switchman who could understand and troubleshoot this circuit was a real craftsman! A bizarre bend of old and new technology resulted was when LCOT (Local Coin Overtime) circuits were added to these trunks. LCOT used integrated circuits and optoisolators for interface to the 48 volt SxS apparatus. Considering that these SxS coin control trunks were designed in the 1930's, LCOT was something to behold. > And who could ever forget digit absorbing selectors, rotary out trunk > selectors [ROTS], E-2 repeaters, level hunt connectors, and the brush > replacement routines for the ringing machines and motor generators. No > rectifiers for that tough switch. Digit-absorbing selectors were rather clever. The digit levels to be absorbed were stored in memories which used BMF technology. That stands for Bent Metal Fingers. :-) There was this U-shaped piece of metal with 10 metal fingers on each side, which were bent with a needle-nose pliers. This metal part (called a "normal post cam") was attached to the selector switch, and rose vertically as a digit was dialed, with the bent fingers actuating a roller switch at a given digit position. Another interesting facit of digit-absorbing selectors is that depending upon the digit sequence to be absorbed, in many case ONLY the LAST digit had to be dialed. This resulted in a dialing "short-cut". For example, if you were served by a CO with a prefix of say, 778, you could usually dial other subscribers within the same CO by dialing 81234 instead of 7781234. Dialing 777777777777781234 would also work. :-) Well, there was the 100A and similar power plants which used mercury vapor rectifiers that gave off a pleasant purple glow. Also interesting is that in smaller CO's the +110 V and -110 V collect and return supplies for coin telephones were furnished by large dry cell batteries. No rechargeable batteries, M-G sets or DC/DC converters - just dry batteries which were periodically replaced. SxS design philosophy before 1960 was dead set against anything electronic. Even a simple rectifier diode - which in some cases could eliminate a whole relay - was taboo, despite the reliability and use of such diodes for over ten years. Timing circuits were implemented in five ways: (1) thermal time-delay relay; (2) Adlake pneumatic dash-pot relay; (3) motor-driven timer; (4) common two-pulse interrupter timing (where the resultant timing value could vary by a factor of 2); and (5) the three-element cold cathode electron tube - which required 130 volts to operate, however. > And what a marvel the power room is.

In view of today's technology, counter-EMF cells are unique - to say the least. Most of them used potassium hydroxide as an electrolyte, on top of which was poured mineral oil to retard evaporation. 1960's vintage counter-EMF cells finally got around to solid-state diodes. > And last of all, don't forget the rubber gloves aprons and your face > shield when measuring the specific gravity of the batteries. While I have only seen them in pictures, until the 1960's there were some large central offices which had battery rooms with open-top batteries. That's right, open-top glass or hard rubber containers with lead plate arrays just hanging over the side walls of the container.

Power cable was primarily of the RHW-type, which used a rubber insulation and deteriorates over time. There is nothing more harrowing than pulling a new cable in a cable rack and watching a section of old 750 MCM insulation disintegrate into dust, exposing the bare conductor. 750 MCM carrying 48 volts will arc and burn through 1/4 inch cable rack steel long before it blows a fuse! > For anybody that does not understand what I'm talking about, or > who remembers parts of SXS switching but not the rest, take > heart.

In the late 1960's or early 1970's the Village Hall was relocated to its current site on the south side of Bryn Mawr Avenue, just west of the Des Plaines River (if you've stayed at the Hyatt Regency O'Hare you were on the north side of Bryn Mawr, across the street of it). The Centel/Bell border ran along Bryn Mawr from the river, west across River Road, to Gage Street. At the same time, the Centel/Bell border between River Road and the river was relocated south to Williams Street, just letting in the new Village Hall and the site now occupied by the Rosemont-O'Hare Exposition Center.

Massachusetts has a legislature which seems to believe that _anything_ TELCO wants is illegal, immoral, fattening and a ripoff of the public. We still have free DA and ten cent pay phones (the ones belonging to TELCO only, of course, not the COCOTs). TELCO asked the DPU for permission to charge for DA calls. The legislature got into the act and started screaming about TELCO trying to abridge the right of free speech (!?!) and ripping off the public and all the more legitimate objections, too. I watched some of it on the tube. Absolutely amazing. But TELCO kept backing off their position to the point that no reasonable person could have objected and still wanted the permission (and didn't get it). They were willing to allow exemption for anyone who claimed a handicap, even with no supporting evidence. They were willing to exempt pay phones. They were willing to exempt new listings and calls FROM new listings. They promised to provide huge supplies of phone books. They were (reluctantly) willing to exempt not just two calls a month but twenty-five calls per month! And still they said their figures showed there were many (ab)users of the system who went far above that level. (They claimed privacy laws prevented them from naming those (ab)users.) This says to me that there are mass users of DA who are using DA as an extension of their business and not paying for it. I can't see any reason not to have them pay their way. Having said all that, I hereby propose a simple technical solution to the problem: Stop making the DA service so good. Impose a two-minute holding period before giving out the number. (Maybe except from pay phones). That's long enough to encourage people to look it up in the book. It probably would get the bulk abusers to implement their own systems with CD-ROMs. Today's service is so good it is actually faster than looking in the book a lot of the time. But a two minute wait is not too oppressive for the occasional legitimate need to find a number that isn't in the book or the occasion when you don't have a book to look in.

I guess it depends on the way it is phrased (isn't that usually the case when it comes to legal matters ? :-) ?). The telco wouldn't say, "XYZ Corp is abusing DA, so we'll charge them more", rather it would say, "Everyone gets that many calls to DA per $100 in phone charges; every call to DA beyond that is $.25", or whatever. In that case they are not charging different parties different rates for the same service, but rather, everyone's call volume determines their rates. It is the singling out of **specific** customers for different treatment which is prohibited to common carriers, not the establishment of different service levels or rate classes applicable to all customers -- we already have some of that, i.e. residential and business rates, etc. The criteria for each such level or class may need to be approved by the PUC, but the principle is already well established.

Not only This is not clear. Currently, DA is charged for. Do you mean make it free again? DA has costs associated with it just as every service does. With all of the different service entities now in the telephone business, the question is who provides DA and who pays for it. If AT&T maintains a DA bureau and you call it to get aunt Millie's number, then make the call on Sprint, what on earth did AT&T get out of the transaction? If you make a DA call for every pay call you make and I don't, why should I subsidize you? > Does anyone in this discussion honestly believe they are talking about > anything more important than marketing schemes?

Recovering costs of operation from users is not necessarily "justice" or "moral", it's just good business. If you have some legitimate question, such as, "Is the amount charged for DA actually commenserate with the costs in providing the service?", then let's talk. Otherwise, you are going to have to accuse every business that charges for its products of being guilty of conducting "marketing schemes". -- John Higdon | P. O.

While I can understand that argument, nonetheless it is flawed: not only **finding** a phone number, but **calling** a phone number is available only through a service the telco provides -- since making a phone call is otherwise impossible, should the telco be prohibited from charging for that service?

This issue of the Digest is devoted, by and large, to some humorous messages I've received in the past week. I'm tired of Caller ID; I'm tired of debating the merits of charging for DA; and I thought maybe you were also. The next time someone starts up the Caller ID thing again, someone please give me a good swift kick as a reminder not to publish it unless I want messages to go on for weeks afterward pro and con. Obviously Caller ID brings the same divisive, heated and ongoing discussion in the telecom group that guns and abortion bring in talk.politics.misc. So in this issue of the Digest, nothing serious; nothing earth-shaking; just a few light-hearted comments to hopefully give you a chuckle or two. For starters, is there anyone at all who hasn't seen the cartoon of the minister standing in a payphone booth saying, "Operator, I want to make a parson-to-parson call"? Well, the jokes will get better as you read further....

Could anyone shed some light on this? Although its seldom required anymore with the new electronic offices, those bottles are local supplies of dialtone. Usually used in areas where dialtone form the C.O. just can't make it 'cuz the cable is too old or leaky... I've answered this question so many times, that I just couldn't resist giving the answer we always used to give back when I was an telco installer. These bottles are actually dry nitrogen used to provide a local source of dry (low humidity) gas/air to pressurize and keep water out of the cable. Most central offices have "air dryers" to provilded a source of dry, low pressure air for the cables. If a splice is open, or if a cable is very leaky, a local source of dry air is required. Dry nitrogen fits to bill for this quite nicely (until some smart-ass screws with the regulator and ruptures the cable or air dam) While we're at it, here's a variation of the same idea: After repairing a phone at a residence (or business) that had no dial tone, some subscribers would ask what the problem was. My stock reply was "Oh, your phone had been in place so long that it had run out of dial tone. I took it out to the truck and filled it back up. Should last for another four or five years now." This was back in the days before interconnect and modular phones and all phone instruments were telco owned. I got in trouble once because a subsciber called the business office and said she was going to Florida and would they send out that nice repairman to fill up all her phones with dial tone before she left, so they would work when she returned. District business office managers have no sense of humor, I found out. Another variation: In step by step (SXS) central offices, phones left "receiver off hook" (ROH) tied up central office capacity. Instead of trying to explain the techincal reasons to the subscriber, we would use one of several stock explanations: - "Your off hook phone makes us run out of dial tone faster." - "Leaving you phone off hook lets the dial tone run out (all over the floor...)" - "It overheats the wires in the central office..." - "The operators get tired of hummming (to make the dial tone sound) (I had a little old lady offer to bring over cookies and tea to the toll board (operator positions) she was so upset that she had put them to all that trouble by leaving the phone off hook) You should have heard us explain cut off problems.....

It is also hooked to an announcing machine (an answering machine that does NOT take messages) and it can control whether or not the annoucing machine answers this call or not. Your objective is to get telemarketers to quit their jobs, get fired for nonproductivity, or end up in a mental ward, not just stop calling your line. What messages can you transmit to people on your "scum list" without the phone company having legitimate reason to disconnect your service? - 30 seconds of silence, then hang up - pick up the phone for 3 seconds to be sure the call gets billed, transmit silence, then hang up. - a recording of a reorder tone, then hang up - for those of you who said something about copyrights on reorder tones, your best imitation of a reorder tone instead of a recording - 30 seconds of modem tone, taking care to meet exactly the maximum transmit volume rules, then hang up - 30 seconds of ringback, then hang up - 30 seconds of hissing, clicking, and an unintelligible voice that might be saying "Hello", then hang up. - an imitation of a machine saying "The number has been changed. Please make a note of the new number, 976-1234.", then hang up. - a recording saying, "I'm sorry, but the number you are calling from is not in service. Please pay your bill, deadbeat, and try again", then hang up. - a repeating recording "Thank you for calling Bay Tea and Tee. Please hold." followed by 1 minute of silence. The machine senses disconnect by the other party and hangs up. - a recording saying, "Please deposit 479 yen for the next 3 minutes", preferably in a Japanese voice, followed by a minute of silence and then hang up. - a recording saying, "Organized Crime Death Squad. Do you have problems with witnesses, telemarketers, squealers, and prosecuting attourneys? Pests eliminated at economical rates. Contact your local Mob representative for details.", then hang up. - a recording saying, "Worldwide Drug Emporium. Cocaine, $5.00 a pound. Marijuana, $90 a gram.

One technique I've found that has worked perfectly for a month or two now is very simple: if *anyone* calls asking for me by name ("Is Mr. Cosell at home?"), I simply say "NO".

In Massachusetts there is a state law which says that New England Telephone must compile a list of people/phone numbers who do not want machines to call them with recorded messages, and that telemarketers with such machines must get this list from NET and not call anyone on the list. When this started, I had my name/number placed on the list, but it does no good. I still get these type of calls. Usually the calls only ask you to speak your name and phone number for them to tape record and do not identify the company that they are comming from. One time I was able to identify the company and tried to file a complaint. No one at NET or any state office I could find would admit to having jurisdiction over such complaints.

A common carrier is obliged to carry (whatever it is that it's carrying) for any customer at the same price. It can (generally) distinguish between *types* of customers (e.g. business versus residential), but can not charge different rates to two given customers of the same type. Like, it can't charge you $12 a month for one residential line and charge Pat $24 a month because he moderates this Digest that's always badmouthing the phone guys... :-) Of course, this is a one paragraph description of common carrier law, which has its origins somewhere back in the 16th century, so there are a lot of nuances I haven't touched on... > If this is the case that there are tiered cost scales for other utilities > then I see no reason why a business couldn't be charged less/more for > a particular telecommunications service. A "business", yes. A *particular* business, no. The phone companies could get away with charging businesses $5 a pop for DA and providing it to residences free of charge -- but they couldn't get away with providing it free of charge to anyone except this telemarketing company (since we always seem to pick on telemarketers even more than the phone guys...) that called them 400 times last month... Although they probably *could* get away with providing, say, three calls to DA a month free of charge and levying a $n fee for any more (which, in fact, some telcos do). -- David G Lewis ...!bellcore!nvuxr!deej "If this is paradise, I wish I had a lawnmower." ------------------------------ Date: Sun, 10 Sep 89 13:58:23 EDT From: Barry Shein Subject: Re: Why DA Costs Should Be Spread Among All Subscribers From: clements@bbn.com (Bob Clements) >Massachusetts has a legislature which seems to believe that _anything_ TELCO >wants is illegal, immoral, fattening and a ripoff of the public.

Although I don't think anything you're saying is "wrong" I do believe there's a lot of moralistic baggage being added to what essentially is business as usual. Nynex (et al) has a monopoly, that's why the legislature gets to meddle in their affairs. If that ever stops being ultimately profitable they're free to relinquish the monopoly. It's not shocking that the legislators take the simple view that adding a new charge for something which was previously free is not in the consumer's interest and advocate for the status quo. Their job is to advocate for what they perceive is their constituent's interest, even if it doesn't seem "fair" (whatever that means in this context.) I suppose the argument is that "we're all paying for it!", the standard battle-cry. I'll be more open to that argument when I hear the BOC say that they'll reduce other prices if they can charge for DA (hah!) After all, if it's a zero sum game then they should be able to show how it will cost all "reasonable" users of DA nothing since rates will be reduced to reflect the shift in revenue stream. Zero-sum arguments generally suffer from the fallacy that that there are only two players in the sum. Generally there are also these creatures known as stock holders and others with claims on any increased revenue stream. Not to mention nice fat raises for the big shots etc. The chances of the savings being passed onto the consumers is usually miniscule although it seems to appeal to the simple mind as an argument, great PR gimmick (profits...they cost everyone :-) Look, these things go on in an atmosphere of pure advocacy. The BOC takes their best shots and the legislature, DPU etc take their best shots and somewhere a compromise everyone can live with is found or else the game ends. As Clarence Darrow once said, "Justice has nothing to do with what goes on in the courtroom, Justice is what comes out of a courtroom." Going back to what I might think is fair, I suspect the whole thing would be settled if they simply charged business for DA (perhaps with a few free DA's per month.) Seems to solve the complaint at hand and they know who the business customers are. Unfortunately they also know damn well that businesses can be clever about getting around these charges, possibly by nurturing private or internal DA orgs etc. That might seem fine by you, but I bet that's not what the BOC is after. I'm guessing there are parameters and goals going on here which aren't being revealed in these discussions.

Sorry, the discussion I was responding to was around areas like mine where DA is not charged for tho it could be extended to yearning for the days when DA was free everywhere. There are various ways to recover these costs, direct chargeback is but one of them. >Recovering costs of operation from users is not necessarily "justice" >or "moral", it's just good business.

Others were adding a tone of moralism to the discussion, look back at the messages. Why would I "accuse" anyone of "marketing schemes"??? I never said there was anything evil going on. Quite the opposite, if the TELCOs found that free DA increased their business enough to more than pay for the DA (which is why DA was free in the first place) by facilitating the use of telephone services then all power to them, everyone wins. It's entirely possible that AT&T and MCI and Sprint etc get the sum benefit of this so it might not be worth bickering over problems you describe, or they could account the total DA's and come up with some scheme to distribute these costs among themselves from their advertising budgets. All I'm saying is that it's not as obvious as people are presenting that "DA costs money, therefore it must be direct-charged". Does Sears charge for their catalogues? There's a lot of precedent to helping people find your products for free, that's all DA is. ------------------------------ From: Chip Rosenthal Subject: Re: Putting A Call On Hold Date: 9 Sep 89 22:35:06 GMT Reply-To: chip@vector.dallas.tx.us Organization: Dallas Semiconductor ssc-vax!clark@beaver.cs.washington.edu (Roger Clark Swann) writes: >X-TELECOM-Digest: volume 9, issue 360, message 3 of 7 > There was a news story I saw over a year ago where a US West spokes person > was asked about the newer features such as caller ID, call block, call > trace, selective forward and so on.

While the rest of the country is moving forward with a new set of standards (ESF framing, B8ZS line coding, etc.), US West is digging in their heels trying to maintain their investment in obsolete equipment. If you ever try to get a piece of T1 equipment into the US West area, you will come up against a strange beast called ZBTSI. This non-solution addresses the issue that a T1 line conveys the timing in the data, and data is represented by pulses. Long strings of zeros mean long intervals with no pulses, and the repeaters can lose track of the timing. The preferred solution is to use a line coding technique called B8ZS which replaces eight consecutive zeros with a special code word containing a pulse pattern which does not occur in normal traffic. The receiving equipment recognizes this code word and restores the eight zeros. Older equipment not only lacks the ability to support B8ZS encoding, but goes so far as to munge it beyond recognition. The US West non-solution is a technique called ZBTSI which pre-empts the T1 facilities data link, normally used for network control and status monitoring, and requires storage and processing of the data on a frame by frame basis. This kludge is totally incompatible with existing standards and future ISDN capabilities, impedes the ability to do useful things with the facilities data link, and reduces call quality by introducing significant processing delays. The spokesman is right, these advanced calling features aren't viable. But it isn't because of any lack of demand, it's due to obsolete network equipment.

Some more 'experienced' CB'ers would hook up a DPDT switch to get 22A and B. Later, channels 24 to 40 were assigned up through 27.405mHz. I seem to recall the old 22A & B frequencies being officially assigned as channels 24 and 25, but I'm not sure about that anymore. Then came PLL (phase lock loop) technology (along about the time of the 40 channel sets). The PLL circuit synthesized the 40 frequencies, but actually 'knew' a much broader set of frequencies. I remember having used my external speaker/PA switch to allow 'below channel 1' (under 26.985) and 'over 40' (27.415 through 27.805) dialable from the channel changer. - paul PS: disclaimer: I haven't touched my CB radio in at least 10 years. -- INTERNET: paul@devon.LNS.PA.US | How many whales do you have to UUCP: ...!rutgers!devon!paul | save to get a toaster?

The so-called A and B channels were really not for CB use at all. They were garage door openers; radio controlled airplanes and similar. When CB was expanded to 40 channels, channel 24 and 25 were squeezed into 27.235 and 27.245 respectively, meaning 24 and 25 are actually 'lower' than 23. Channels 26 through 40 follow evenly upward 27.265 through 27.405. And yes, those PLL chips were really something, weren't they! With a little luck and a golden screwdriver, those guys could get the thing to oscillate all the way up to ten meters. But the feds started raising cain with Uniden and Motorola, among others, and forbade the further manufacture of the chips which could be programmed like that.

J. Chin (BNR Canada) of CCITT working party XI/5 (1987). The title of the report is "Specification technique for stage 2 supplementary service interactions". In this report there was a section under the subheading Types of functional interactions. The author indicated in this section that some services are functionally incompatible. The particular example that was given involved the CFU (Call Forwarding Unconditional) and CCBS (Completion of Call to Busy Subscriber which is just a retry service) services. The example goes like this "... A user activating CFU, when being scanned/monitored for CCBS recall, will cause the scanning/monitoring to be withdrawn or abandoned." My question is why withdraw the scanning ? Why not barred the user who is being scanned from activating CFU ? There are a few more examples from this report which from first reading don't seem to make sense. If Mr S. J. Chin or friends are reading this newsgroup could they make a comment ? Are there later edition of the CCITT report floating around ?

Before then, it was the Western California Telephone Company and was it a lot of fun! (As some of you may know, GTE has spent a considerable amount of its resources buying up Ma and Pa phone companies.) In those days there were two COs: 354 and 356. Each has its own peculiar brand of non-standard SXS. Each allowed five-digit dialing with Los Gatos. The 354 office had this weird PBX-style ringback with short rings and a fast cadence. 356 had short rings with a very slow cadence; in fact 1A2 key systems used to time out between rings. WC hardly ever installed standard key systems, however. Instead they had these Automatic Electric phones that had a hold button next to each line and required no backroom equipment (KSU). The 356 ringback sounded like terminal flatulance. To call the neighboring communities of Saratoga and Campbell, you dialed the seven digit number. The prefix would land you in the appropriate Bell CO, and the last four digits were counted by the distant switch, which at that time was either crossbar or SXS, depending on the prefix. To call any of the other local destinations, it was necessary to first dial "9", wait for second dial tone, then dial the seven digit number. "9" connected you with the San Jose tandem, which accepted the entire seven digit number dialed directly from the Los Gatos subscriber. Long distance was reached by dialing "112" plus the ten digit number. An operator would ask for the number you were calling from. Some of us found a better way for long distance, however. After dialing "9", the tandem restricted the calls to local only, however we discovered that if you dialed a local call, then flashed the switch hook, there would be a ka-klunk-plunk, then silence. Dial pulses seemed to have no effect, so we tried something else: MF. Jackpot! You could key "KP+[anynumberknowntomankind]+ST", and you had a free call. The standard phone issue was, er, well uh there was no standard phone issue. It seems they used anything they could get. There were AE, Kellog, Stromberg, you-name-it. According to some of the GTE switchmen I talked to later, the cable plant was in about the same shape. From the CO to any given subscriber, no one could be sure how many times the pair changed wire types and gauge. Trying to create equalized loops was a nightmare (even more than GTE's usual). Considering everything, it was probably a step up for the citizens of Los Gatos when GTE came to town, but it took away the fun of endless hours of playing with that weird system. When GTE took over, they immediately replaced the CO equipment with standard issue AE directorized step, which had no interesting quirks other than it being totally unreliable at completing calls. Even all that is now gone and is now electronic (354=EAX and 356=GTD5). This October the 354 office will probably become a remote from the 356. Los Gatos now has six prefixes. Glossary term of the day: foreign exchange; a service GTE provides customers who really need phone service, usually provided out of a Bell service area. -- John Higdon | P. O.

Two WECO installers were completing an expansion to a New York Telephone SxS CO located in a small community. Part of the expansion effort including the installation of a vacant level intercept recorder to replace the previous use of reorder tone. Since the intercept recorders do not come with any pre-recorded messages, which are usually added by telephone company personnel after installation, one of the WECO installers recorded a messsage for test purposes which went something like: "Your call cannot be completed as dialed, #$%&*#. If you are so *&#$%@ stupid that you cannot dial correctly, then you should not use the telephone." Bear in mind that this message was only used to test the operation of the recorders and the associated intercept trunks, and there was allegedly no intention of ever having the public hear the message. The intercept recorder and trunk wiring was completed and tested on a Friday. Accidentally or "otherwise", one of the WECO installers failed to busy out the the new intercept trunks and unbusy the old tone trunks, thereby leaving the recording available for the public to hear. On the following Monday morning the situation was discovered when the WECO installers returned to the CO. They quickly busied out the new trunks and "erased the evidence". According to a TUR (Traffic Usage Recorder) which was temporarily installed in the CO, several hundred calls had been made over the weekend that resulted in the intercept recording. This was probably 10 times the expected vacant level intercept traffic, so it was obvious that a number of people had "discovered" the recording and wanted to hear it for themselves. While the recording was the talk of the community for several days, neither the rather nervous WECO installers nor the local New York Telephone switchman ever heard a word about it from their respective supervisors. Perhaps no telephone subscriber ever complained... <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Sun, 10 Sep 89 16:07:44 EDT From: jsol@bu-it.bu.edu Subject: Memories of SxS Yes, those magnanimous switches were something to behold. What I found most amusing was the absorbing of digits. In the Niantic CT exchange (they just went DMS or ESS this year) (203-739), you only had to dial 9-xxxx to get local numbers. The local calling area was them and New London (all started with 4), Norwich (all started with 8) and then recently Old Lyme (434 -- which broke the 4-meant-new-london rule into 44 for New London, and 43 for Old Lyme). Anyway, you could dial: 7373737373737377773333377777333331-800-536-8000 and it would happily interpret the 1 at the end of the absorption, and feed the rest of the number to the tandem. In any case, as a kid growing up, I had PLENTY of fun with this. In Hamden, CT: (203-288, 203-248, 203-281), you could dial 231 if you wanted 281, or 238 if you wanted 288. That's sort of the same thing as absorption but more complex, since there are two digits you can absorb. I believe (203-684) Stafford Springs, CT is still a SxS exchange, as is Orange, MA (508-544), but the number is definitely getting smaller. I think there are more fun things you can do with an ESS now than ever before. Like "Intelledial" (residential centrex). I just got mine and love it. --jsol ------------------------------ From: Karl Denninger Date: Fri Sep 8 20:32:43 1989 Subject: Re: Can We Outlaw Junk Calls?

Next you'll scream about "junk mail" -- although it costs you nothing to throw it away (just as it costs you nothing, including your time, to IGNORE that ringing phone.) It's time that our society started putting responsibility with the INDIVIDUAL. Legislation is not the answer. Your suggestions are insulting. The solution to the problem you are facing is simple -- don't answer the telephone. We have become a society enslaved to that damn little bell, and it's time that the people realize that just because it rings YOU DO NOT HAVE TO ANSWER IT. If you want to insure that you don't miss something important then buy an answering machine and screen your calls -- tell your friends and relatives what you're up to so they don't hang up on it. Instant problem solved. The number of people who are hung up on legislative solutions amazes me. We used to be a country of free-thinking and free-acting people. Now we all of a sudden want to call for laws to ban this, that and the other thing. Whether it's telephone solicitations, guns or drugs, the point is the same. We are increasingly unwilling to take responsibility for our own lives and instead look to the government to solve all our problems. The trouble with this "solution" is that it isn't one -- in getting our carrot (regulation of this or that) we give up our freedom. You don't like telemarketing? I don't either. But you don't hear me screaming for laws -- I simply turn on the answering machine, and only pick up the phone if I want to. The rest can listen to my incredibly boring message, and waste the tape in the machine if they're so inclined. It can always be erased.

Not I ... I don't get charged for it as a regular DA call, nor do I pay for it otherwise (as a line-item charge on my monthly bill, mind you). And why does the international DA Operator on our side *insist* on talking? They could (for all practical purposes) just ask you where you want to talk to and connect, but *no* ... they feel the need to verbally "collect" the information so they can then relay it inaccurately to the foreign DA operator... to be fair, international DA from the other side seems to lose the same way ... why won't they let me talk directly to the foreign DA operator? Curious, # Henry Mensch / / E40-379 MIT, Cambridge, MA # / / [Moderator's Note: There is no 'international DA operator' that I am aware of. The AT&T long distance operator simply handles every foreign DA request I've ever made. I agree it seems like a waste of time for the operator to stay on the line, however customers have been known to connive and con less sophisticated foreign operators into completing the call for them, obviously on a no-revenue basis to AT&T. I'd think this could be resolved by the AT&T operator warning the other end "information only, do not connect", as they used to do when connecting customers to little dinky manual exchanges for DA a few years ago. What is especially pathetic is the amount of time required to get DA in some mid-east and far eastern countries. Even Jamaica can be bad, but try calling Malasia for DA: she'll take the info and be gone off the line for five to ten minutes. India is another example of *terrible, terrible* very slow DA. For that matter, it may ring twenty-five times before they even pick up. Maybe AT&T figures Americans would be too confused by it all. I am reminded of the time I visited (pre-Castro) Cuba; I tried to call back to the USA from Havanna, and the Havanna operator was ringing the old Miami Overseas Inbound Operator on the cable. Miami must have been busy because it rang about forty times and finally the Havanna operator said to me, "Sorry sir, but the United States is not answering today!"

Why not allow DA operators to connect the call. In this fashion, if you request DA on a call, and are connected, there is (first time per number only) no fee. If you call DA for the same listing, or call DA and do not choose to place the call, then you are billed for it. This solves a number of problems: 1. Businesses which merely use DA to "verify" phone numbers would pay full cost. 2. LD companies could do the same thing, which would prevent people from calling AT&T information and using MCI (or whatever) to place the call. 3. Pay phones could be made into general exceptions to the rule. 4. All the legitimate exceptions could still be in place. A couple of details would need to be worked out: 1. How do you define "place a call?" I would go for connection, six rings, or busy signal (simpler than a later check against billed calls) which would probably get rid of "Sure, place it!" followed by an immediate hang up. Overall though, I think this is the type of SERVICE that a phone company should be providing, and there is no reason LD companies shouldn't compete on the quality of their DA services. Oh, and Barry Shein wrote: >>Does Sears charge for their catalogues? There's a lot of precedent to >>helping people find your products for free, that's all DA is. Well, last I looked, Sears, Penney's, and the rest charged for their catalogues, but gave you a merchandise certificate of about the same value good for mail order. (With Penney's, it is a $4 catalog, and a $5 certificate) This seems almost exactly the same, and I think it should work.

Apparently you haven't tried to get a Sears catalogue lately.

Had BT not been a state owned and run monopoly within living memory, your expectations would be more correct. For many of us, BT (and the GPO in general when they were one) represented a commonly owned *NOT FOR PROFIT* service (albiet one that could and sometimes did make money, which of course was creamed off into the exchequer rather than re-invested or even (shock horror) rebated...) and our views were formed as a result. Even in a post-thatcherist world BT has cross-subsidization and other requirements placed upon it which make it more than just a money-making enterprise. In a world where the phone can be a lifeline, but one denied to many because of more general economic deprivation, the phone-provider can (and in my view should) have certain moral obligations to meet. Before BT left the public fold it was made quite clear that certain services, such as DA and maintenence of phoneboxes were viewed as essential. BT has consistently tried to renege on these and other social commitments, to the extent that OFTEL has been forced to act, and its image as the most complained-about utility only recently was assuaged by very marked improvements in staffing directed towards payphone repairs. I understand one of the first "steamlining" activities to take place was the CENTRALIZING of all DA enquiries. Of course they under-estimated the number of lines required, and call-queing was the norm rather than the exception. Yes, public ownership was not always rosy. The state's blatent creaming off of all profits and separation from the GPO did not (in my opinion) help. Nonetheless, Once upon a time BT was *not* just a company selling a resource, and if some of our expectations reflect that, so much the better I say! -George -- Internet: G.Michaelson@cc.uq.oz.au Phone: +61 7 377 4079 Postal: George Michaelson, Prentice Computer Centre Queensland University, St Lucia, QLD Australia 4067. ------------------------------ From: Leonard P Levine Subject: How I Deal With Junk Calls Date: 11 Sep 89 20:49:34 GMT Reply-To: len@csd4.csd.uwm.edu I ask the caller to give me his/her number so that I can call them back as I cannot speak with them just now.

When the telemarketeer for a local newspaper calls, they often pretend they are checking on your subscription. "Hi, this is Julie from the Times-Union. Are your papers being delivered all right?" This person doesn't have any idea whether you subscribe or not--it's just their way of finding out whether you are a potential sucker for their spiel. I always say "yes" and the person thanks me and hangs up. One time, though, I goofed, and told the person that I bought the paper every morning on my way to work, and didn't need a subscription. I forgot it was an afternoon paper, so she pointed out that I was thinking of the wrong one, and I had to listen to the spiel. Now, sometimes you get someone doing a telephone survey about something, and you don't feel like spending 20 minutes trying to rate the texture of buns from McDonalds hamburgers on a 1 to 5 scale. Usually they ask if you or anyone in your family works for an ad agency or anything. I've sometimes told them my wife does, even though I'm not married. The cruelest thing I ever did was just to stop talking. When the poor woman realized I wasn't responding, she started saying "sir, sir, are you all right? Sir?" After about a minute she hung up, but I think she really did get worried. For some reason I never have used what I worked out to be my best strategy. The whole idea is for us to make the callers waste as much time as possible on an unprofitable call. Remember the person calling is often just a person who needs a job, and maybe didn't have any experience for anything more exciting. There's no need for you to initiate a nasty exchange. If the person really gets obnoxious, I'd say anything is fair, though. Anyway, I always figured it would be good just to ask them to hold on, because someone's at the door, then pretend that you forgot all about the phone. Chances are they will hang on for quite a while, expecting you to come back on. If they wait 3 minutes for you, before hanging up, they will have lost time which they could have used to call several other people. Eventually (in theory) this form of marketing will lose its cost-effectiveness, and the company will go back to direct mail or something. -- "ANGRY WOMEN BEAT UP SHOE SALESMAN Dave Fiske (davef@brspyr1.BRS.COM) WHO POSED AS GYNECOLOGIST" Home: David_A_Fiske@cup.portal.com Headline from Weekly World News CIS: 75415,163 GEnie: davef ------------------------------ From: Brian Gordon Subject: Re: Coping With Junk Calls: Like Nancy, Just Say No Date: 11 Sep 89 15:06:19 GMT Reply-To: Brian Gordon Organization: Sun Microsystems, Mountain View In article Bernie Cosell writes: >X-TELECOM-Digest: volume 9, issue 363, message 5 of 7 >I find junk calls easy to deal with (I get the usual 5-10 per week) --- >it is just a matter of taking a similar attitude as toward junk mail: >finding a bunch of ways to quickly (and low-stressingly) dispatch with >the things.

While I have great respect for the quality of Western Electric apparatus, I have an equal degree of respect for the quality of apparatus manufactured by the various GTE operations, having had firsthand experience with the products of both organizations. In particular, I take exception to your use of the term "infamous" as applied to Automatic Electric. I will provide a bit of historical perspective before delving into more contemporary issues. First, I would like to point out that the Automatic Electric Co. (A.E.Co.) started out in 1901 as the successor to the Strowger Automatic Telephone Exchange Co., which was formed in 1891 by Almon B. Strowger. Strowger was the inventor of the first practicable telephone switching system, commonly referred to as step-by-step (SxS). The Bell System and Western Electric (WECO) had no automatic switching apparatus to speak of until they _literally_ learned the art from A.E.Co. Beginning shortly after World War I, AT&T (i.e., the Bell System and WECO) began a major effort to install SxS systems designed and manufactured by A.E.Co. A.E.Co. began a major training program for AT&T personnel, starting with 40 Bell System engineers in Chicago in 1919. While WECO did introduce the panel switching system during the mid-1920's, panel was never economically viable for central offices of less than 3,000 lines. There are also many qualified people (especially within the Bell System!) who will state that the panel CO was the most mechanically complex and unreliable switching apparatus ever built. A.E.Co. later licensed various patents to WECO, which then began manufacturing SxS apparatus on its own beginning in the 1920's. However, at various times right up to and including the 1950's, the Bell System purchased SxS apparatus directly from A.E.Co. There were a significant number of SxS CO's installed by the Bell System in small communities following World War II which utilized A.E.Co. apparatus, most commonly the A.E.Co. 35E97 SxS system. The central office area where I live, Clarence Center, NY, was first installed by New York Telephone as an A.E.Co. 35E97 office. So, the point is: before one blatantly bashes GTE/A.E.Co. on the quality of their switching apparatus, don't forget they were in the automatic telephone switching business long before WECO! 1/2 :-) If one were to compare SxS apparatus manufactured by A.E.Co. and WECO, they would be virtually indistinguishable - both from an appearance and from a quality standpoint. The only significant difference between the two manufacturers is in the supporting trunk circuits which are mounted in 19 or 23 inch wide apparatus frames. A.E.Co. apparatus has always used round coil, flat-spring relays for both switching and trunk apparatus, whereas WECO used round coil, flat-spring relays (220-series) just for SxS switches, with trunk apparatus originally using U- and Y-series flat spring relays, followed by introduction of wire-spring relays in the mid-1950's. WECO also introduced wire-wrap terminals on relays, other components and terminal blocks during the 1950's, which was several years before A.E.Co. introduced the same style connections. From an overall quality standpoint, in my humble opinion A.E.Co. SxS apparatus is on par with that of WECO. Period. With respect to overall quality of CO switching apparatus newer than SxS, in my humble opinion GTE/A.E.Co. has been on par with that of WECO. In particular, I refer to A.E.Co. apparatus such as the analog No. 1 EAX and No. 2 EAX, and the digital GTD-3 EAX and GTD-5 EAX. The first electronic switching product of WECO was the 1ESS, first installed at Morris, IL from 1960 to 1962, and made commercially available in 1965. The first electronic switching product of A.E.Co. was the No. 1 EAX first installed at Portage, IN in 1965 and made commercially available with an installation in St. Petersburg, FL in 1972. The No. 1 EAX used integrated circuits and was a generation newer than 1ESS when it was made commercially available in 1972. The first WECO apparatus to make extensive use of integrated circuits was the 2ESS, which was not made commercially available until 1973 (it was first field tested in Oswego, IL in late 1970). > When I worked at Western Electric it seemed like the most > satisfying jobs were those where we replaced AE equipment with ESS > machines (1A ESS at that time) for GTE of California.

I rather doubt that replacement of A.E.Co. SxS apparatus with ESS was any more "satisfying" than replacing WECO 350 or 355A SxS with ESS. There is no comparison between the lack of SxS features when compared to those available with ESS. With respect to the replacement of crossbar apparatus with ESS, most crossbar CO's (even No. 1 crossbar) were already modified for DTMF service by the early 1970's. The offering of previously unavailable DTMF service would probably be most noticeable to any customer following an ESS conversion. With respect to other GTE manufacturing organizations, GTE/Lenkurt is probably the largest single manufacturer of microwave, FDM multiplex, T1 and fiber optic apparatus in the U.S., with the possible exception of WECO. I am not certain why GTE operating companies have been singled out for bashing in this forum, but I suspect that IN TRUTH their problems are no worse than those of any Bell operating companies. GTE, as an overall operating telephone company, is as well organized as AT&T, and maintains uniform standards, practices and procedures as well as AT&T. Now, in my opinion, if you want to see telephone central office which is real trash, just look at some of the apparatus that has been turned out by Stromberg-Carlson (like X-Y, their original progressive switching apparatus, some of which is still in service), or that turned out by ITT (their Pentaconta crossbar switching office, as an example). In closing I would like to point out that I own no stock in GTE, and I am not their spokesperson. I am simply trying to give matters some perspective and to be fair. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?"

Sun, page 2A has an article... [regarding the enclave] Buesingen is the enclave, just outside the Swiss canton of Schaffhausen, and about a mile from the main part of West Germany. In PRACTICE (except for such things as phones and license plates), the enclave is Swiss. But the pay phones take German coins only, and calls to Schaffhausen are 9 digits and cost 8 times as much as "domestic" calls. And he replied: Well, that's not really accurate - they do have German post offices too, and can use the substantially lower German postal rates. Just last year, or was it two years ago, they got a Swiss Post office as well (8932? not sure any more), so they only pay national rates to send letters to the people they do business with mainly. An adjustment on the phone system is not far from coming, I'm sure, since a wave of liberalization is sweeping the PTT at the moment. I wrote: ... what does PTT stand for? And he replied (responding to my query about PTT at the end): First, it's just my opinion, based on several years of watching Swiss PTT politics concerning regulation, allowing of third party equipment installed on subscriber lines, relations with neighboring countries, etc. Second, calls from CH *into* Buesingen (sp?) are taxed as national calls, even from as far way as Zuerich - there's a special area code. This is true for all border regions. Third, it's normal that calls to nearby towns within Germany are nine digits. If you live in a pop. 2000 village, you most likely have a 4-digit area code and a 4-digit number. To call the neighboring one only right down the road, which, if its in a separate "Kreis" (county?), likely has its own 4-digit area code, you would dial 0++ which is 9 digits. 9 digits is also the norm in CH, but there are fewer area codes (max 2 digits), so it's not so often a problem. Schaffhausen, being Swiss, has 5 or usually 6-digit numbers, so if you say it takes 9 digits to call SH, I would imagine that there's a special 2-digit area code for it on the German numbering scheme. Given the size of SH, that would be a pretty special concession already, since the shortest area codes in Germany are two digits, and these are only for the big cities (viz. Berlin 30, Munich 89). Otherwise, it's 11 or 12 digits going via the international protocol (004153+number). Fourth, it is also normal, even within Switzerland, to have the suburban rate be much higher than the city rate. I lived 400m from the Zuerich town border, and yet my phone bills (mostly for modem calls) to ZH were about 10 times higher than my colleagues who lived in ZH proper (same area code, too). My boss was nice enough to reimburse me, though. So, while I do believe that an adjustment will be coming, I think it will probably be to install Swiss phone boxes, and leave them on the German switch (the new electronic boxes (made by Hasler, I think) accept multiple monies w/no special hardware, and are made for use in many different countries. They already have some at the French train station in Basel). I think that this will solve the most irritating problem, that you can't use the same money for the coin box that you do for beer, or that works in the coin box down the street. Perhaps cross-border calls will get knocked down a rate classification or so as well, but I am not so certain of this. It would be, of course, be perfectly in the German character to insist to wait until they could manufacture their own Multi-Munz box (by Siemens or AEG, perhaps). :-} By the way, I believe I got the post code for Buesingen wrong. I did not bring any Swiss telephone book with me. However, the opening of the Swiss post office on "German sovereign territory" made the papers all over the country. Finally, "PTT" (I thought everyone knew this), is a quite European concept - it means Post, Telephon und Telegraf in Swiss-German, with the expected variation as you change the language. The idea is that of a single government monopoly agency which offers all these services, and usually banking as well (it's nice - you can always telephone at the post office for essentially local rates and pay money afterward - pay any bill, and cash a check, too. The clerks always know how to speak the local language - American post offices compare poorly :}. In Germany its called the Bundespost, or Post for short (but they stil do telephones, too). PTT is understood most everywhere, though. ------------------------------ From: Michael Katzmann Subject: I Bought an AT&T Payphone Organization: Rusty's BSD machine at home Date: 10 Sep 1989 00:00:00 At a hamfest recently I purchased an AT&T payphone.

I didn't mention this to Patrick specifically, so I apologize -- my mistake. In the case of health benefits (the point that the strike centers on), I think the union is in the wrong. Most other companies, including those with IBEW employees, do require employee contributions to health plans. I think that $4 per week is a reasonable donation. Of course, one could argue that it will start at $4 per week and end up at $40 per week in some future contract. I really don't want to get in a protracted debate about the strike.

I think Orange, like Athol (508/249) is a crossbar, tho' I could be wrong. But in the (still relatively rural) area of Massachusetts between Worcester and the Quabbin and stretching all the way from the CT to NH lines, SxSs are the exception, rather than the rule. They all have five-digit dialing, and many (as in my town) will accept four digits within the exchange. They all have their quirks, but the one I find most annoying is that the limited number of long-distance circuits results in a busy upon dialing "1", the limited number of circuits to each neighboring town can result in busy after the first two [disambiguating] digits, etc. This makes it fairly important to listen to the progress of your dialing, which is impractical with a dialing modem, or with a phone which (like most pulse/tone switchable phones in pulse mode) blocks out the noise while dialing is in progress. In general, New England Telephone seems to have made better progress migrating New Hampshire to ESS than Massachusetts; remaining SxSs in the southern half of NH tend to be privately-, even family-owned (as in Chichester). They're saying all-electronic by 1992, but many of the towns in Worcester County and much of 413 has yet to be done. I only know of one SxS conversion in Mass. in my four years in New England, and that's Pepperell (508/433, I'm sure there are a few others).

PT] Not only is your statement true, but even more amazing is the nature of Strowger's occupation: he was an undertaker! Rather than merely recite some details about the development of "automatic telephony" (a term no longer used, but which was first used to described dial switching systems as opposed to manual switchboards), I am going to do so in a much more colorful fashion by quoting few paragraphs from a book in my collection: "Automatic Telephone Practice", by Harry E. Hershey, Fifth Edition published in 1946. Hershey was an engineer who joined [Strowger] Automatic Electric Co. in 1910 and retired in 1945 when he was in his 70's. Hershey was well acquainted with the founding fathers of Automatic Electric, and himself played a significant role in shaping the growth of Automatic Electric and SxS telephone switching technology. Comparatively few people have heard of Hershey, who in fact held 51 patents in the area of telephone switching systems. Hershey was a most colorful character who has written five editions of a most unusual textbook - unusual in that about 15% of the textbook is devoted to various discussions of a "philosophical" nature. "PREFACE TO FIFTH EDITION" "In the words of the immortal Elbert Hubbard, 'If a man - - make a better mouse-trap than his neighbor, though he build his house in the woods, the world will make a beaten path to his door'". "Strowger Automatic is such a mouse-trap, made by six men - an undertaker, a clothing salesman, an electrician, and three farm boys. These men had no cultural background (there was scarcely a high school education among them), yet they were able to out-think and out-fox others in the communications field who had hundreds of technicians and millions of dollars behind them." "These men were not handicapped by a profound knowledge of mechanics or electricity; they merely had a job to do and the God-given light of genius which permitted them to select the right approach and the best means of execution. In the early twenties, when Panel was first being introduced, John Erickson was approached with the query, "Will the new Panel System put Strowger Automatic out of business?' He answered, 'Twenty-five years ago I gave careful consideration to that approach and decided that it was workable but too costly. We have nothing to fear from Panel.' Now that the Bell System has delivered its own verdict on Panel, we know how right he was." "Of the Erickson brothers, John was the mechanical genius and Charley the electrical wizard; this made for a happy balance between mechanical gadgets and circuit kinks during the early nineteen hundreds. The Martin influence was always in the direction of circuit accomplishment; but even in 1917 when the first edition of this text was published, there was still a reasonable relationship between mechanics and circuits. Both were simple; and, as the writer demonstrated on many occasions, it was possible to teach a man Strowger Automatic within a reasonable length of time." "As the years passed and the old heads were retired for one reason or another the mechanical gadgets disappeared and the circuits became more and more complex. In the normal course of events the fifth edition of this text should have appeared in 1928; but at that time it seemed that the circuit designers, like Lord Ronald, were about to mount their horse and ride madly off in all directions at once. And so it seemed advisable to watch the pot boil for a few years." "The few years have grown into twenty; the circuits have grown into thousands and their complexity has increased geometrically. As a student's text this compilation will scarcely be as satisfactory as were the earlier editions. Its principal excuse for being born is that the writer, now freed from the necessity of making a living in the telephone business, is at long last in a position where he can call the shots as he sees them and takes this opportunity of describing the present Strowger Automatic System in a brochure replete with historic anecdotes and with numerous references to men responsible for its rise and for whatever decline it may have suffered." ... "Old John and Charley, Keith and Martin, were very, very right indeed. Strowger Automatic is still going strong after fifty years of competition which in many instances was far from being fair.

PT] I have heard (and read) this story in enough places that I believe it to be true: Charles Strowger, back in 1891 (I think) was an undertaker somewhere in the depths of small-town America, in a town with two undertakers. His competitor's wife was an operator, and by virtue of her job was able to provide her husband information on practically every death in town (or at least anyone wealthy enough to have a phone). It is also alleged that she would route all calls to an undertaker to her husband. In his determination to eliminate the job of telephone operator, and thus remedy this injustice, Mr. Strowger went out and invented the Strowger switch, otherwise known as the step-by-step. Each switch has ten tiers, each tier a semi-circle of ten contacts. One solenoid hits the contact arm (or whatever the proper term is) once for each dial pulse in the first digit, and it ratchets up. The second solenoid handles the next digit, and turns the contact arm over to the proper contact. And now you know the origin of pulse dialing. As a side note, I must say that the MIT dormline system is one of my most favorable memories of MIT. The service was sh*tty, and the lines were rotting, but it was worth it to be able to go down to the basement of Walker or Ashdown and watch the calls come in at 11 pm. You could track the wave of calls coming in from the trunks on one side of the room, through the various (meticulously soldered) racks, and out to the dorms. It was a mechanical system that was beautiful in its simplicity - for instance, the power supply in Walker used two relays that would trip on high or low voltage, turning the knob on a variac to compensate. With a few part-time students to burnish contacts and replace them when they wore out, and modern insulation on the underground wiring to the dorms, it could have lasted well into the next century. Not bad, when you consider that (I think) it was built a bit before WWII and installed soon after the war, and was in continuous operation since then. So much for nostalgia. I have to admit that the phone service provided by this antique was lousy.

Unfortunately it doesn't explain away reality. I remember growing up in Oakland. Our telephone was connected to one of those "unreliable" panel offices, which seemed to work pretty much 100% of the time. We moved to southern California and in GTE land we were shocked. We learned what it's like to not have calls routinely completed. We even complained to repair and were told, "Oh, that's normal. You know, we're so heavily overloaded." Interesting that neighboring areas served by Pacific Telephone didn't have those problems. Ask anyone who has had any *real experience* and they will tell you the truth about AE directorized SXS. I sat in Los Gatos for several hours one day and determined that AE step has about an 80% call completion average. Not really impressive. When I called to complain I was told that the problem was with the "old" equipment that would soon be replaced. When they installed their highly-touted 1EAX we were all told, as Mr. Lippman pointed out, that this equipment was more advanced than the ESS being used by Bell in the surrounding areas. Why then did it routinely crash, not offer most features available in Pac*Bell, and find itself already on the replacement list if it was so wonderful? If AE equipment is so damn good, then GTE must be completely inept. The truth of the matter is the service is substandard by any measure. All service and feature offerings are 5 to 10 years behind Bell, and their prices are even higher (they have special tarrifs). Pac*Bell has had to delay implementation of their 900 services in the Los Angeles area for at least a year while GTE tries to figure out how to set up their equipment to put the calls through. In the Bay Area and in San Diego, where there are insignificant amounts of GTE, the 900 service is already implemented. In area code 714, GTE was responsible for the implementation of 976. It's the only area code in the state that has no 976 to this date. Believe me, if there was even the slightest indication that GTE was pulling its act together, I would be the first to cheer. But you have much smaller companies like Contel who provide service that runs rings around GTE. All of my associates have indicated that they would gladly live in a Contel area before one "served" by GTE. And these opinions come as a result of actual experience, not just word-of-mouth reputation. Glossary term for the day: subscriber carrier; GTE's answer to undercapitalization John Higdon | P. O.

The company, Intellicall Inc., which makes pay phones for private ownership, says its computerized operator system will reduce the need for human operators and save consumers 5 percent to 7 percent on operator-assisted calls made from pay phones. Intellicall's electronic operator, called Intellistar, uses voice synthesis and recognition technology. The regional Bell phone companies have also begun testing automated-operator systems, but the Intellicall system differs from those in that a microprocessor, or "brain," is in each pay telephone and not in the central office switch. Intellicall says its arrangement is less expensive for processing a call than that at the Bell companies. To make a collect call, the caller dials the number of the party to be billed and the computer asks the caller to give his or her name and records it. The system makes the call, plays back the name of the caller and asks whether the charges will be accepted. The system listens for a yes or no, and processes the call accordingly. Industry analysts expect the computerized system to bring Intellicall a significant share of the $2 billion pay-phone market, in which the government began allowing companies to compete for operator-assisted calls made from the nation's 1.6 million pay telephones this year. The American Telephone and Telegraph Co. had previously held a monopoly. Stephen Polley, Intellicall's chief executive, said pay phone owners who use the Intellistar system would reap commissions 10 percent higher than those offered by other alternative-operator service companies. Polley said the company has shipped more than 36,000 electronic operator systems since the product went on the market last year. The company is also putting the improvement into the more than 80,000 pay phones it has already installed. # Henry Mensch / / E40-379 MIT, Cambridge, MA # / / [Moderator's Note: I can see some definite disadvantages to these devices when cheats use them to relay messages for free: User dials call indicating it is collect. Phone says,"Record your name" and user says, "Meet me at the airport at 7 PM". Phone places call, and announces to recipient, "I have a collect call from (pause, tape kicks in) 'Meet me at the airport at 7 PM'; press one to accept the call, or two to decline." Naturally the recipient declines to accept the call, the phone says thank you and then disconnects. No charge to caller or callee, but a message has been given, and for less effort than is used now to send a coded message past the operator. The owner of the phone still gets stuck for the cost of the one minute station dialed call. At least the live, human operator would never tolerate this. You might be able to sneak past a coded message, but never could you be so brazen as to deliver an uncoded message under the pretense that it is your name for collect call authorization purposes. The AT&T operator would not accept your statement that 'meet me at the airport' was your name. And with the traditional payphones, the central could keep track of repeated game-playing of this nature from one particular group of phones. But if the private pay phone just has a little chip inside which records whatever you say, and records over it with the next person, a month after the fact the owner of the phone (or the maintainence company) gets a bunch of one minute calls and never knew what hit them. Too much opportunity for fraud here.

Public thanks are in order to the AT&T "billing questions" people for solving the problem to my complete satisfaction. I guess competition works miracles... The background: Years ago, I purchased a Star Micronics printer (yes Star Micronics is the offending company.) It worked fine for straight ascii printing, but I recently needed to do graphics. My software had no support for this particular printer and any attempt to print graphics resulted in a "Venetian blind" effect. I wondered if some emulation mode could be set. The manuals were of no help and all 4 800 customer support numbers there had been disconnected. No one on the net seemed to know what the current number(s) was (were), or of any solution to my problem. How I got the information: After not finding any number for Star Micronics in any phone book I have, I call Directory Assistance. In two minutes, I have the Star Micronics Tech support number. It is a 900 number. Having heard about these, I ask how much this would set me back: 50 cents is the answer. Odd, think I, usually these numbers are at worst regular numbers, many, like Epson, which I had just called minutes earlier, are 800 numbers. Maybe this is to avoid frivolous calls... Maybe I haven't been in the real world lately... (how widespread is this kind of thing for peripherals such as printers, modems, etc... anyway?) In any case, in less than 4 minutes I had the answer to my question: it is not possible to use this printer for graphics without modifying the software that drives it. This printer (a Gemini 15X) is not Epson or IBM compatible. The outrage: When I got the phone bill, the call cost $32.00 !!! This works out to $8.00 a MINUTE or $480.00 per hour. Kind of expensive to tell me that there is not a dip switch I can set on a printer which I could probably not sell for $50.00. This kind of rate might be reasonable for up to the second information that might allow commodity traders to make thousands per minute in the futures markets, but to answer a question about a product I already paid them hundreds for?! And it's not like I'm asking complex and time-consuming OS maintenance questions either... Apparently, the directory assistance people should not have quoted a figure, since apparently the 900 charges vary by company. Also, that kind of rate seems to be the norm. Well, maybe for dial-a-porn numbers, but I'd never heard of such thing for plain customer support. I won't even touch the issue of the propriety of the phone company referring people to those numbers without telling them in advance about the exact cost. I hope this saves someone a nasty surprise...

U.S. operators who are used to the Bell standard 18 second max DA number response are often staggered at the time it seems to take certain European PTTs.

Instant problem solved. Fine--except for one problem. What about those folks who can't afford an answering machine? There are millions of the new "working poor" who need a telephone for their jobs, yet barely get by on a hand-to-mouth existence. I don't think it's fair for you and me to be able to solve our problems by spending money, while it's an option that many people don't have. It's just another example of how the "haves" have so many advantages over the "have-nots". And the argument that "answering machines aren't very expensive" doesn't apply. What is "not very expensive" to a single working mother who's trying to decide whether to buy beans vs. bread for the kids tonight? Imagine her some evening, frantically trying to cook dinner, stop the kids from fighting while getting them to do homework, do the house cleaning, all in a short enough time to maybe get a few hours sleep before the boss calls again--all interrupted by three calls from people trying to sell her some aluminum siding. Don't get me wrong--I think the bulk of Karl's article is very good, and his points about our society seeking legislative solutions for everything are highly valid. I urge everyone to re-read Karl's article, and think about how we all abrogate the responsibilities that we should be maintaining. I think Karl has zeroed in well on one of our most glaring faults. But I must take issue with his paragraph above. The idea that you can solve your problem by purchasing Product X only applies to those who have the money. Remember that such solutions always leave out a certain percentage of people--who are already rather resentful at being left out of the mainstream--and serves to futher widen the rich-poor gap.

I am not familiar with the operation of newer coin telephones which have synthesized voice, mag stripe readers, alphanumeric displays, etc. since my "nuts and bolts" experience with such apparatus ended during the 1970's before these new-fangled gadgets came into existence. However, I am quite familiar with more common coin telephones made by WECO and other vendors, so perhaps a comment or two may be helpful. In the case of WECO coin telephones, from a standpoint of feature identification, a 1-type telephone is of the standalone "box"-type, and a 2-type telephone is of the "panel"-type often found in shopping malls, airports and other places of public assembly. The A-series is a telephone for coin-first operation (long ago MD-ed and almost non-existent), the C-series is convertible for either coin-first or dial-tone-first, the D-series is for dial-tone-first only, and the E-series is for postpay operation only (non-WECO CO apparatus). A following number of 1 indicates rotary dial and a following number of 2 indicates DTMF dial. An example is a 1D2, which is a box-type, dial-tone-first DTMF-dial coin telephone. There is no way that an an A-series or C-series (configured for coin-first) coin telephone will work on a conventional (POTS) loop-start telephone line. These coin telephones require coin(s) to operate the totalizer until an an initial rate is deposited, which then puts a ground on the ring side of the line, which then requires the CO to place a ground on the tip side of the line. The presence of this foreign ground on a conventional loop-start line may well preclude any attempts at dialing and interference-free transmission. Even more important, is that all money deposited remains in the coin hopper until the CO apparatus sends collect (+100 to +130 VDC) or return (-100 to -130 VDC) voltage between tip-ring and ground to operate the coin relay and restore the telephone for another call. The coin return lever will NOT cause the deposited coins to exit the coin return chute, nor will it reset the totalizer. So the point is, a coin-first telephone is useless for regular telephone use unless one modifies the telephone circuit to bypass the totalizer and coin control components. A C-series (configured for dial-tone-first) or D-series coin telephone will _probably_ work on a conventional loop-start telephone line PROVIDED that you do not deposit any coins. If you deposit coins, you cannot retrieve them without supplying coin-control voltages (not very practicable!), although you could open the upper housing and manually remove them from the coin hopper (not very convenient). You canNOT use the coin deposit function to allow a call only in the presence of a coin. It is sort of interesting to note that the 1A and 1C series coin telephones have electromechanical totalizers and have a maximum initial rate of $ 0.55. The 1D series coin telephone has an electronic initial rate circuit, which is programmable to a maximum initial rate of $ 3.15. We can certainly see that AT&T is well prepared for inflation! :-) The bottom line is that if you are thinking of using your coin telephone to actually collect money for calls, this is an impracticable idea since as far as I know, ALL AT&T (i.e., WECO) coin telephones require some type of central office coin control. This is, of course, not true of some newer non-AT&T coin telephones which are intended for "do it yourself" operation on conventional loop-start telephone lines. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Tue, 12 Sep 89 14:03:05 EDT From: Bernard Mckeever Subject: Absorb, Absorb, Absorb Reply-To: bmk@cbnews.ATT.COM (bernard.mckeever,54236,mv,3b045,508 960 6289) Organization: AT&T Bell Laboratories I sure enjoyed Larry Lippman's SXS article the other day and got a kick out of his explanation of BMF technology for digit absorbing selectors. Larry and others mentioned dialing situations where the digits would be absorbed over and over, I have seen this happen but it was always a trouble, and resulted in wrong numbers or not enough digits. Let me explain. The level 7 tandem office I worked in had 2nd selectors set up to absorb digits 2,3,4, and 7. The switch would only allow a digit [any digit] to be absorbed once. If the exchange you were calling was 733 you could dial 743 and still get the right party. On outgoing calls all levels except 7 and 6 were routed to the appropriate toll or stepper tandem office by the first selector. Level 6 calls went to a group of special selectors that routed 61X calls to the test board, repair bureau, or test connectors in the office. level 62, 63, 64 .....etc. routed to the level 6 tandem trunk groups or vacant code announcement. Level 7 calls had several available routings. 71 vacant code 72 absorb 73 " 74 " 75 third selector 76 route to end office 77 absorb 78 route to end office 79 route to end office 70 vacant code Lets get rid of the 75 calls first. There were 3 separate offices that had 75 as the first two digits of the office code. The third digit was required to identify the correct trunk group for the end office. With the 4 groups left, the 3rd digit [still on the 2nd selector] would cut in on any level dialed. This is the only way to direct the call to the proper connectors for call completion. In this office anyway. Incoming calls were treated much the same. All level 7 calls entered on a digit absorbing incoming 2nd selector, except some trunks from the 3 offices using office code 75X, and were treated as above. The trunks from the 75X offices would come in on a non absorbing 2nd selector if the 2nd digit had been a 2, 3, 4, or 7. I should restate, this was a level tandem office, not an end office. Also the arrangement of the 75X offices was not a normal one. End offices had different arrangements that could allow 4, 5, and 7 digit dialing arrangements. I have no doubt that some offices will allow a few designated digits to be absorbed over and over, but I just was not lucky enough to work in one. PS. If anyone reading this is going to be at the NCF in Oct. and would like to get a look at some modern digital transmission equipment located nearby let me know.

I attended MIT in the early sixties. At that time, and maybe because it was MIT students asking, New England Tel allowed lots of tours. We visited Strowger SxS offices, panel offices, #1 crossbars, one of the new-fangled #5 crossbars (Wellesley, as I recall) and one of the main Boston tandem offices. I have a very strong recollection of the LOUDEST room in the phone system. It was in the above-mentioned tandem office. Today its function would be implemented in RAM backed up by a floppy disk or tape cartridge. Then it was implemented in metal punch cards and solenoids. What it did was translate from three digits of the phone number to a trunk group and a number of digits to send on that trunk group. Let's see: You dialed 213. Grab a trunk to White Plains and send all ten digits. Or: You dialed 358. Grab one of these dedicated trunks to Wayland (a SxS) and send the last four digits only. Each such inquiry resulted in a large "WHAM!" as a bunch of solenoids shoved huge trays of metal cards around. The selected card had the answer punched in it. The cards were metal because of the great number of read cycles. Updating the routing consisted of punching a new metal card and replacing the old one in the bin. Every once in a while there was a distinctive "WHAM-WHAM!" in among the many random "WHAM!"s. We were told that was a "come-again-six" operation. That meant that the three digits weren't enough to select the trunk group - say 603 for NH - and the "ABC" code (3 digits after the area code, total six) were needed. The equipment holding the number had to "come again" (request another cycle) with the rest of the six digits. The largest Strowger office I ever toured was Madison WI. It was close to 1970 and they still had all Strowger SxS gear, no panel, no crossbar. It was absolutely huge, and sparkling clean and well maintained. As for not-so-beautiful equipment, I earned my spending money by working on MIT's dorm phone system. Some of it was new equipment (Baker House) but most of it was ancient. East Campus had a manual cord switchboard when I was a freshman. A couple years later it got dial equipment. The "new" equipment was junked from the old John Hancock building as no longer being repairable. The interbay thousands-of- triples cables (and the huge battery cables) were cut with hacksaws and the bays were trucked over to MIT. I and a couple other guys spent the summer reconnecting it all. Soldering on the top of an old MDF (Main Distribution Frame) is bad enough. Soldering on the bottom, with solder dropping into your face, is the pits. Some of this gear used plunger line switches that were so old that they weren't even "restoring". A plunger line switch is a wonderful device which can't be described without a diagram. It performs the function of a Strowger "Line finder". Each subscriber line controls a plunger - a solenoid that drives a probe-like contact into a curved array of contacts. This connects that subscriber to a first selector (which provides dial tone and accepts the first digit). Then the whole array of plungers pivots over to the next available position for a free selector. (If none are available, this whole assembly of 50 or 100 plungers sweeps back and forth looking for one.) A "restoring" plunger is one that restores the position of your line's plunger to the current position of the array when you hang up. Then you can get the next free selector if you pick up again. Without this "restoring" feature, the plunger stays over the position it just used. If you pick up again, you get the same first selector. So if you happen to get a dead selector, a "restoring" line switch lets you try a different one by hanging up and re-seizing your line. On a "non-restoring" switch, you are stuck with the bad position until you hang up and wait for ten other people to make calls so the switch sweeps back and picks up your plunger. Batteries; yuck. Motor-generated dialtone and busy interrupters; yuck. Grasshopper fuses; yuck. Sticky B relays; yuck. Those were sure the good old days.

Date: Wed Sep 13 19:41:08 1989 From: Ken Jongsma My GTE California bill had an interesting insert in it this month. The California Public Utilities Commision is considering the following proposed regulation of COCOTS: 1) Local Calls from *all* payphones would be .20 for 5 years. 2) All payphones will provide free access to emergency, repair, directory assistance, 800 and *local telephone company operators when 0 is dialed*. (No word about 10xxx access though.) 3) All payphones will provide clear signs indicating rates, dialing instructions, free access, the identity of the phone vendor and the long distance carrier serving the phone. 4) Prices approved by the CPUC to be strictly enforced. 5) An additional charge of .30 (called "Paystation Charge"), could be added to 0+ calls. this is addition to the current .40 charge for credit card and 1.00 for collect charge. I think this is terrific and long overdue. The only one that isn't clear is number 5. Presumably the new .40 charge is in place of any excessive charge the local vendor has programmed their phone to collect. I don't know how much luck CPUC is going to have enforcing these rules on out of state calls, but I wish them all the best. They certainly would serve as an excellent model for the rest of the country. The insert goes on to give dates and times of the hearings and an address if you wish to mail comments. Presumably everyone in CA is getting this insert, so I won't include that info. Ken@cup.portal.com [Moderator's Note: Please keep us posted on the results of this.

If the exchange you > were calling was 733 you could dial 743 and still get the right party. Most digit-absorbing selectors had a wiring option to absorb a given digit ONCE or REPEATEDLY, with the latter case allowing for an infinite number :-) of the same digit to be dialed. Sometimes in an office with two consecutive identical numbers (like 773) there was no choice but to set the 7-level for repeated absorption if the first selector was to be a combined local/toll/tandem selector. Therefore, the instance of repeated absorption was often not a case of trouble, but was simply a quirk of the particular office switching layout and the particular digit-absorbing selectors. Some digit-absorbing selectors were more complex than others. A full-featured digit-absorbing selector (like the SD-30976) was sophisticated (I use this term loosely :-) ) enough to decide on a level by level basis whether to absorb once, absorb repeatedly, rotate to ATB, select a path to a second selector or select a path to an outgoing trunk. The above was a pretty common digit-absorbing selector and was used on No. 1, 350A, 355A, 356A and 360A SxS apparatus. I remember it "fondly". :-) <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Subject: Mail Connections With GEnie Date: Mon, 11 Sep 89 16:13:39 CDT From: "David W.

Reply-To: bmk@cbnews.ATT.COM (bernard.mckeever,54236,mv,3b045,508 960 6289) Organization: AT&T Bell Laboratories Being new to this group I never took the time to research its' history but if what I suspect is true, the group has changed quite a bit over the years. The group name, comp.dcom.telecom, suggests a natural evolution from the comp {computer} hierarchy to a group interested in machine to machine communications, comp.dcom , and further specializing in machine to machine communications over telephone facilities. Today we almost have usable computer to computer communications ;-} over telephone facilities, in fact we are using it now. Thanks to T1 pipes and digital transmission circuits, relatively large amounts of data can be moved from point A to point Z quickly and accurately. But, and by now you may have guessed where I'm headed, It wasn't always so. One of the early forms of "data" communications that still has a few applications left is the telegraph. Several of the older alarm reporting systems used by fire departments cling to this technology because it still works, and the tariffs for telegraph grade facilities are cheap and hard to change for political reasons. Your favorite alarm company may still be using McCulloh systems for home and business protection. Today several vendors have T-CXR channel units for this service, but it is still a basic series [just like old Christmas tree lights] circuit that causes the Telco nightmares when the circuit goes open. Western Union at one time had a huge telegraph network that spanned the globe. Often telegraph circuits were transported over analog carrier systems. I can remember the 43A carrier system that combined up to 17 separate telegraph circuits on one N1-CXR channel [4 khz bandwidth]. We had two systems of N1 carrier that each had 10 43A systems on them. From time to time one or both of the systems would fail when the A1 cable under the river started to go belly up. NY 7 Telegraph [the control office] would be on the tie line in seconds arranging a reroute. Other early applications of data transmission were TWX, another Western Union service. The Bell System was also allowed "some" TWX like service. This service used private network switches and addresses were 10 digit numbers. This is how the now well debated 510, 610, 710, .....etc. area codes were used. Strangely, this network was to a large extent maintained by the Bell System and much of the equipment used to provide the service was located in Long Lines switch rooms. Other Common Carrier [OCC] decisions forced AT&T to cancel the contract with W.U. and legal battles began. W.U. cut over to its' own satellite based system several years later. TWX service ran at several speeds depending on the model of TTY you had, TTY=Tele TYpewriter, the later one would operate at 110 - 150 baud. What a racket that mechanical device made at such "high speeds". Another common data application was the dumb terminal to host connection, used mainly with time share systems. Connections were typically 300 baud, and the modems were much bigger than a bread box. Connections were available in two flavors, dial-up and private line. Well thats enough for today, time to go for now. Bernie McKeever 508-960-6289 [Moderator's Note: TELECOM Digest began publication August 25, 1981.

I sympathize with your problem, but I do not agree with your definition of the problem. As I see it, the problem is (1) directory assistance gave you the wrong rate. Based on that, you should request a chargeback from the local exchange carrier. (2) the serving company did not provide on-line rate information. Lines like this should be answered with a recording that states the rate and gives you 15 seconds to get off. On the other hand, *paid* *technical* *support* is not a problem but a solution. Technical support is expensive to provide, and vendors need to recover this cost. This can be done in several ways: (1) Increase the product price to cover giving support for free. This may increase the cost of the product by as much as 100 %, and may result in the product being priced out of a mass market into a niche market (which in itself reduces the support need, since product features and documentation can now be accurately targeted to the application and the technical level of the users). (2) Make support available only to paying subscribers of a support contract. This approach is becoming fairly common. Such a support contract may run in the following ranges: - $75-$100/year for a personal computer program for checkbook balancing and tax preparation - $500/year for high-end personal computer word processing/page layout programs or macro-programmable spreadsheets - $1000/year for 8-user Unix systems - $5000/year for Mainframe TCP/IP packages - $10000/month for IBM's MVS operating system on midrange processors (3) Bill by the hour for all support. I have had support telephone lines announce "please have a current Mastercard or Visa ready for the person answering the line". (4) Ration support by having only one incoming line which is generally busy. (5) Not make any support available. Most vendors are moving from option 1 to a combination of options 2 and 4. Personally, I feel that options 2 and 3 are the most fair, with an allowance for free support in a warranty period following product purchase (which is a subset of option 1). I work in the Customer Service department of a company that produces data communications equipment for high-end systems (from VAX-class machines and up). While some of our support needs stem from product deficiencies uncovered in forever changing customer applications, much of our support effort is basic education in features of the customer's operating system or 3rd-party software that interoperate with our equipment. It seems fair to me that those customers that spent money up front to send their staff to appropriate training classes should not pay to provide "free" support to those customers that did not. We support according to option 2 with free installation support for 90 days after our product shipment. We would like to be able to bill by the hour for out-of-warranty customers with consulting needs. We have looked into using 976- or 900- type billing for such consulting, and have discovered that the California PUC will not allow this. (1) Interactive 976-services are not allowed in California (2) 976-services can only be located in certain premise locations leased by Pac Bell (in some cases to brokers that will sublease) and cannot be located in our GTE service area. The closest 976-access point is in West Los Angeles, 100 miles from here. (3) 976-calls are limited to 3 minutes, and there is an upper limit of something less than $5.00 on the charge. (4) 900-services are not yet generally available in California. Most of the Pac Bell has recently opened up, but again, our GTE service area is running behind. (5) 900-services are subject to the same restrictions as 976-services. In short, I think the $32.00 service charge is not unreasonable; but I am sure you would not have spent it, if you had known the price. ------------------------------ End of TELECOM Digest V9 #372 *****************************   Date: Thu, 14 Sep 89 1:22:26 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #373 Message-ID: <8909140122.aa21867@delta.eecs.nwu.edu> TELECOM Digest Thu, 14 Sep 89 01:20:07 CDT Volume 9 : Issue 373 Today's Topics: Moderator: Patrick Townson Caller ID in Maryland (Ken Jongsma) Central Office Answering Machine (Ken Jongsma) Re: Who Pays For International DA?

It's the same logic used in some areas to charge amateur radio phone patches commercial rates. They simply lump the ham club in with other small businesses. Another example is how 976- numbers are currently being treated. I personally hate to see 976- service as a class disparraged by a few low-rent operators but that's what's happened. Even if the courts were to overrule a classification based on current law or regulation, it would be easy enough to change the offending law given enough public will.

PT] Yes there is truth to that story. A. B. Strowger was an undertaker in Kansas City, Mo. When a close relative of his chief competitor (I think it was a sister-in-law) became the operator, Mr. Strowger noticed a sharp decline in the calls he received from customers. To combat this, Mr. Strowger invented the SXS switch. Kevin L. Blatter AT&T - Bell Labs Standard Disclaimer ------------------------------ From: John Higdon Subject: Re: Can We Outlaw Junk Calls?

One of the nasty little realities of life, and it applies to telephone service as well, is that those with money can afford to have more than those without. To my knowledge, it has always been that way. One of my clients owns about fifteen automobiles, including some very expensive classic cars, while I drive an '85 Blazer and a motorcycle. Not really fair, is it? In this case, unlike depravation of food and shelter, the receipt of junk calls is hardly life-threatening. I know people who have their butler screen their calls, but it hasn't occurred to me to hire one for myself. Glad no one has suggested that as a solution, since as a member of the working poor, I can't afford one:-) Yes the "haves" have many advantages over the "have-nots". Else why would anyone want to become a "have"? It's also true by definition. John Higdon | P. O.

Telemarketer Gets Sued Date: Thu 14 Sep 1989 01:00:00 Alan Schlesinger's stock in trade is suing people. But you might say his stock is too hot to handle at Merrill Lynch these days. A Boston lawyer who hates telephone solicitors, Schlesinger sued Merrill Lynch after the brokerage firm ignored 'repeated requests' to quit calling him with investment proposals. To Merrill Lynch's surprise, he won an injunction. Indeed, he sued them *two times* and won. The second time was after an unwitting broker called him in violation of the court order prohibiting it. "This is something that bothers a lot of people, but they don't have the sense they can do something about it," said Schlesinger, whose best retort is a tort, it would seem. In the second suit, the court awarded him $300, for the costs of his prosecution of the matter and for his time spent on the phone with the brokerage house's phone room. "He is using an atom bomb to deal with a gnat," said William Fitzpatrick, chief lawyer for the Securities Industry Association, faulting Schlesinger for doing what comes naturally for an attorney: "Being a lawyer myself, I can only guess he doesn't have enough brains to just hang up the phone."

Needless to say, there have been incidents of information "abuse" which have caused New York Telephone to maintain a reasonable level of customer information database security, and to conduct periodic audits of database access. While I am not certain of the law in other states, it is a specific _crime_ in New York State for a person to obtain billing and physical plant INFORMATION about a telephone subscriber without having prior authorization to do so. The actual text of Penal Law 250.30 is as follows: "A person is guilty of unlawfully obtaining communications information when, knowing that he does not have the authorization of a telephone or telegraph corporation, he obtains or attempts to obtain, by deception, stealth or in any other manner, from such corporation or from any employee, officer or representative thereof: 1. Information concerning identification or location of any wires, cables, lines terminals or other apparatus used in furnishing telephone or telegraph service; or 2. Information concerning a record of any communication passing over telephone or telegraph lines of any such corporation. Unlawfully obtaining communications information is a class B misdemeanor." I don't know of any attempted prosecutions or case law for the above criminal offense, although the law has been on the books since 1965. This law is not intended to cover any act of eavesdropping, which is covered by other sections of the Penal Law. A reasonable interpretation of this law would include billing records of toll calls. This law is one of the reasons why New York Telephone is sensitive to "unauthorized" use of ANAC (Automatic Number Announcement Circuit). While it would certainly be stretching the imagination a bit, a person using ANAC in an attempt to identify someone ELSE's telephone pairs could be prosecuted under this law. New York Telephone security personnel are a frustrated lot; while they would love to prosecute people (and there have been cases where there was sufficient basis for prosecution, but where it was declined) and set an example for purposes of deterance, such prosecution would also disclose details which could facilitate others to commit the same unlawful act. As a result, New York Telephone security personnel generally limit prosecution to larceny in one form or another. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Wed, 13 Sep 89 20:59:33 EDT From: "John R.

Private numbers (i.e., not served by the Pentagon PBX, or whatever it is called) are Area 703 numbers served by C&P of Virginia's Columbia Pike Central Office, about 2 miles west of the Pentagon. This includes pay phones in the bus and subway station just outside the Pentagon building line and businesses located in the mini shopping mall inside the Pentagon. I also once saw a modem, fax or private line number (I forget which) for someone inside the Pentagon whose exchange was listed as 202-553. 553 is really in 703 (but temporarily mapped into 202 until Oct 90). The pay phones in the Arlington Cemetery subway station, about a mile north of the Pentagon, are also served out of Columbia Pike. The border to the Rosslyn CO must be just north of there. West of the Cemetery, U.S. Route 50 is the border. The Crystal City/National Airport area is served by three (!) central offices. Most is served out of Columbia Pike but the southern portion is served by the Old Town (Alexandria) office. The border between the two occurs roughly at 23rd Street South and is like "melted cheese" with many overlaps and no fixed border. This can be done because both CO's serve the same Rate Area ("Alexandria/Arlington"). The third CO is a recent addition: Crystal City now has its own. It serves a subset of the area served by Columbia Pike. It was probably opened because of the large number of three and four mile long cables that were being installed from Columbia Pike to the burgeoning number of Crystal City office buildings. New prefixes serving Crystal City/National Airport customers are run out of the new office. Crystal City CO codes are (703) 271, 418 and 769. Columbia Pike is (703) 486, 521, 553, 685, 892, 920, and 979. Old Town is (703) 548, 549, 683, 684, 706, 739, 836 and 838. Within the airport, phones have mixed Columbia Pike, Crystal City and Old Town numbers. Even pay phones right next to each other have alternating CO's attached to them. I imagine this provides a level of backup in case a CO goes down. >By the way, time of day is set up as a local call throughout Maryland.

Another prefix may also have to be "patched up" to work in more than one Area Code after the change: 202-810. This is used by the Arlington, Virginia, cable TV company (and possibly others) to allow ordering of pay per view movies and events using ANI technology. To order, one makes a 7-digit call to the 810 prefix *from one's home phone*. C&P reports to the cable company the number you called from. The cable company's billing equipment goes to its data base and looks up what customer that phone number belongs to. It bills that account for the movie and also looks up the electronic serial number of the addressable cable box that subscriber possesses. The box is authorized (via a data channel on the TV cable) to descramble the ordered event. If Cable TV Arlington wants to continue giving its subscribers a 7-digit number to dial to order PPV, C&P may have to make 202-810 reachable with only 7 digits from nearby 703.

PT] Any truth to that? Yea, verily! Almon B. Strowger was a mortician. He invented the dial phone precisely because he feared (whether rightly or wrongly I don't know) that the operators were (or might have been) diverting his calls to his competitors. The history of Strowger switching was one of things most everybody who worked for Automatic Electric learned very early on the job. Not all of us may have thoroughly memorized the story, but as best as I can recall the facts are as the moderator suspected. Larry is also right on the mark in regards to switching equipment. I worked on the #1 EAX and the GTD-5 EAX, and I wouldn't contradict anything he said. Of course, since I still work for GTE, my opinion might still tend to be favorable towards the company. And of course anything I say here is strictly my own opinion -- I do not and cannot represent GTE in any way.

UK Yes in the UK we do object when BT proposes to charge for directory enquiries, I lot of eople seem to forget that the whole structure of the telephone system is very different over here. Essentially BT STILL has a monopoly, but now a private one. Yes we do have just two other telephone companies - Mercury Communications and Hull Telephone Department (this one serves just ONE city). Mercury cover a small part of the country, and as they have to use BT local lines, are not any cheaper than BT for local calls. There's another point we still pay for local calls over here. Am I right in saying that in most other parts of the world, local calls are either free to residential customers at off peak times, or they can be for a small subscription? But here are local calls are still charged AND timed at about 1p/min in cheap rate time (6pm -8am). Now that's quite expensive, and there is NO option available to have untimed calls - i.e. pay 5p for the whole call. We have to PAY for Bt to give us charge advice on a call - even now that it's part of our new digital network, and is completely automatic - accessed via a star service. BT has had the reputation in the past of 'fleecing it's customers'. Well that is certainly true, and in the UK I understand we are the second most expensive country as far as telephone charges go. There is even no toll free 0800 number to speak to the Telecom accounts department, who can't issue itemised bills in most part of the country yet. Worse to come the effective cost of a 2min peak and standard rate call will DOUBLE in October - they are cutting the time for 1 unit (LOCAL) from 120 seconds to 60 seconds!! So we are justified in expecting things like Directory enquiries to be totally free of charge, don't you agree? Clive Carmock (cca@cs.exeter.ac.uk) P.S. I would be interested to hear from anyone who could give me billing example of the different call rates/times in the USA, and would be interested to have details of the OFF PEAK LOCAL calls to residential customers - ie; do you have to subscribe to a service to get these free? ------------------------------ From: John Higdon Subject: Telephone Technique Date: 14 Sep 89 18:49:47 GMT Organization: Green Hills and Cows Something never mentioned is the different dialing technique required for different offices. From the time I was wee todler my family had telephone service provided out of common control offices. Panel in Oakland, crossbar in San Jose. (A brief stint of "number please", but we won't get into that. Besides, that's common control, isn't it?:-) Anyway, In my late teens I spent some time in Norfolk, VA and the surrounding areas. Got the phone installed and discovered that I had very lousy luck getting my local calls to complete. Never having been subjected to SXS (which is what my phone was served by) I was not familiar with the necessity for each stepper to "find" a path to the next level. So I would dial the number at warp speed, and as a result, pulses would travel down the line before the next level was ready to receive them. Result? No call. It took a few days to get used to this. I was even treated like some backwoodsman. "Don't you know you have to dial slowly and carefully? All us big-city people know that!" -- John Higdon | P. O.

For those who were not loving geography too much while in school, Belgium is in Europe and its capital is Brussels. Like in many European countries, the telephone and many other comm- related things are a state monopoly. The operating agency is called RTT, which means 'Regie des Telegraphes et des Telephones' - that should be transparent even for non-French speaking people. Unlike what happens in many other European countries, it has nothing in common with the postal service. The monopoly used to be very very strong. Just knowing that the voice was being transported by electrical signals may have been an infraction. The user was expected to use his/her finger to dial, to speak into one end of the thing and listen to the other end, and that's it (I nearly forgot : and to pay the bill within 10 days, including when in holidays, or be disconnected a few days later). Telephone intruments were wired directly into a wall box, without any form of connector. Everything was provided by the RTT, except some specialized things like high speed modems, which then had to be certified by them (and also the terminal equipement connected to the modem), a procedure that could last for a long, long time... Things have been relaxed somewhat : now telephones are attached to the network using connectors, and the user is even expected to bring back his telephone to a commercial center in case it needs to be repaired or if moving. There are no plans I know of to allow alternate carriers, but the terminal equipment market is now open, except for the first instrument on a line. Every item must still be type-approved, but a new agency, distinct from the RTT, is being created to perform the tests in order to insure more fairness. The user may also extend his interior installation himself, using approved wire and components. That's surely enough for today. If there is some interest in more details, I could write further short articles on subjects like : numbering and dialing, tariffs, RTT procurement and industrial policy (juicy), data communications, ISDN. Disclaimer : my shortsighted views only.... [Moderator's Note: Please send along future installments in this series. We've had very little discussion of Belgium in the Digest to date.

There was one redeeming feature of the above mechanical monster: the routing cards were read optically using light beams and photocells, which was pretty state-of-the-art - for 1950, that is. The outputs of the photocells had to drive relays to convey the translator information to the marker. Now, knowing WECO design philosophy as I do, I would bet that those photocells were either of the selenium photovoltaic variety and directly drove a damn sensitive relay (like a 280-type polar relay), or they were of the cadmium sulfide photoresistive variety and drove a relay using a cold cathode tube. Ain't likely that WECO would have used an electronic circuit using a conventional vacuum tube as an amplifier to drive a relay. ANYTHING but a conventional vacuum tube in a piece of WECO switching apparatus! :-) Mechanical monsters of the 1950's and 1960's which rival the above routing translator were the massive CAMA perforators and readers.

The invention of this particular device was a vital achievement which simplified previous designs of SxS switching apparatus. The 200-point linefinder as we know it today was invented in 1928, and rapidly replaced the Keith Line Switch.

On a recent trip there, I noticed that a local business in the South Street neighborhood of Philly had a phone number posted on its sign: 215 925-9999. Some Bell of Pennsylvania pay phones in 215 also now have NXX-99XX series phone numbers on them. Philadelphia is Bell of Pennsylvania territory. Most of the BOC's have had standing rules for many years that the NXX-99XX series of phone numbers was to be for internal phone company purposes only (test tones, test silence, verification operator, test boards, etc.). This reserves 1% of the numbers in each prefix for this purpose. If BellPa is now assigning the 9900 series to ordinary uses, it may be because they are running out of numbers in area 215. I don't have a complete list on me, but from what I can remember, virtually all the NNX series of prefixes are used up in 215. My understanding of Area Code splits is that Bellcore hands out new Area Codes when the controlling Local Operating Company for that Area Code can prove that it is within a certain percent of running out of numbers, *assuming that the existing number base is being used in the most efficient possible way.* I would imagine that Bellcore strongly suggests that prefixes with a 1 or 0 as the second digit be implemented first, before splitting the Area Code, since this maximizes the number base within the NPA and minimizes the number of times the nation at large must endure NPA splits. In many Area Codes, there is much in the way of older switching equipment which cannot handle three-digit combinations with 1 or 0 as the second digit when used as local prefixes. In these NPA's the split occurs when the NNX combinations run out. Examples: California 714/619, Massachusetts 617/508, and most if not all the NPA splits which occurred prior to 1980. If the controlling LEC can prove to Bellcore that they can't handle N1X/N0X prefixes, then Bellcore allows the split without those CO codes. Is BellPa using the 9900 series phone numbers while it rushes to make all its Southeastern Pennsylvania switches N1X/N0X compatible? Or will it run out of NNX combinations and have to split anyway? I assume that last-minute brinksmanship is not allowed since NPA splits take plenty of planning.

Let us imagine the following scenario: I buy a phone and lease/rent a local and long distance service to perform various local and long distance services for me. Now I have particular things I wish to do with my phone. That is I wish to allow people to call me, and I'd like to call some people. (people includes businesses). In the previous utopian society I lived in, I was happy to have anyone who wanted to call me call. However, recently I've been contacted by an increasing number of people that I don't want to talk to. So I got an unlisted number and only gave it to people I wanted to talk to. Unfortunately, I still got calls from people I did not wish to talk with. In fact, I got even more calls from people I did not wish to talk to than I got with the previous number. Well, I've decided that I'm not going to talk with anyone who is not willing to identify themselves before I have to talk with them. Right now I'm up in the air as to whether you will have to provide your actual phone number to me or some other means of identifying yourself. In either case, if you aren't willing to provide your number or some sort of identifying substitute, I do not wish to talk with you. It is that simple, I will not talk to you unless you provide the identification. I'm happy and your rights are not being violated because you don't have to call me. And the fact that you don't want to provide the identification makes it very clear to me that I don't want to talk to you, and everyone is happy. There are also people I wish to call to whom I do not wish to provide my identification. I'll simply enter a code before the number and the phone won't send my identification before attempting to place the call. Now, if the receiving party doesn't accept unidentified calls, great! I'm happy and the recepient is happy! However, if the recipient is the type that still wants to take the call eventhough the identification is missing then great! They can simply pick up the phone and everyone is still happy! So everyone is happy. You and I and everyone else can choose to accept or ignore identified or unidentified calls. And you and I and everyone else can determine on a call by call basis whether or not our identification is sent before the call. We have now re-attained our utopian society. You are, however, still at a little risk from this solution. That is that I can do whatever I wish with you identification once I receive it. I could publish it or sell it. Well, if you are worried I'd do that or anything else you might not approve of, I'd strongly suggest you don't call me. I'm very much "an eye for an eye" sort of person, so I've now decided that your identification must be your phone number. Once, again you don't have to call me, and I don't want you calling me unless you provide your actual number. There are some problems with this system. For example, what if someone is calling from a public phone whom I wish to speak with. The obvious solution of a portable ID is useless because those ID's will be misused and we'll be back to square one. Or perhaps they will work well enough? There are solutions to the public phone problem, as there are solutions to the Caller ID question even if Caller ID is legislated out of existence. In fact, Caller ID has existed in our society, for those who can afford it, for far longer than the posters to this forum seem to suspect. -- <> Brian Litzinger @ APT Technology Inc., San Jose, CA <> UUCP: {apple,sun,pyramid}!daver!apt!brian brian@apt.UUCP <> VOICE: 408 370 9077 FAX: 408 370 9291 ------------------------------ From: Pete French Date: Thu, 14 Sep 89 09:43:43 -0100 Subject: Oh No - Not THIS Again !!!!! >[Moderator's Note: Well Larry, your history is right on the mark.

And an old story has it that the >inventor did so because he was paranoid about the operators diverting >profitable business calls from him to one of his competitors. Any >truth to that? PT] Oh no - time to dig up this one again. Almon Strowger was a Kansas City undertaker. In those days calls were connected by hand by an operator. The operator was the sister (or was it cousin) of a rival undertaker and she was surruptisiously diverting calls for Strowger to him. Mr Strowger was, understandably, a bit irritated by this and so set about devising an automatic exchange to get round this problem. This is what is commonly known as a "Strowger" exchange - although I think the Americans call it "SxS" for some reason. When I joined British Telecom this is one of the first stories we were told about the history of telephones. It was quite interesting at the time - since then the story has been told at almost every introduction to something that I have been to. Just about every BT student must know it off by heart by now. If any of you get a chance to go in a Strowger exchange then do so - they are far more interesting than any of the other types - simply because they move and do things. They are a bit loud though - you need ear-defenders in some of the larger ones. But it is quite facinating to atch the uni-selectors and two-motion selectors do their stuff. At one point in out training we were allowed to play with a simple one ( uni-selector->dual-motion slector->end selector) and you could dial and wwatch the progress of the call as you did so. Another interesting this is to stand in front of the "wall" of meters and listened to all that clicking ("Those clicks are paying your wages sonny") They are always clicking - but no matter how hard you try the ones you are looking at are never the ones that move. I also find it interesting that nobody has designed an electronic version of Strowger. Mechanical parts wera out and surely a solid-state replacement for each of the units would be very cheap and more reliable. There are still a lot left in operation. -Pete French. | British Telecom Research Labs. | "The carefree days are distant now, Martlesham Heath, East Anglia. | I wear my memories like a shroud..."

It's good to refresh the memory. And yes, it is widely believed that Strowger the undertaker was upset that his competitor's wife was the local telephone operator. I don't doubt it -- it's a gruesome business to think about though. GTE-Pacific has had some particular problems, though. It's not apocryphal that many (many!) of their customers are very upset. I once spoke to the mayor of Santa Monica, who was quite upset about it too, like most of her townspeople. So why is this true? I don't blame entirely blame GTE Corp. for this. California's regulatory system has at times been just plain nuts. All states regulate local telcos based on Return on Investment. All investments go into a Rate Base, against which all revenues minus expenses are compared. That provides an ROI figure. If it's too low, the telco gets a rate increase. If it's high, they cut rates. Most of rate hearings are devoted to determining the "right" ROI, comparing stock market expectations of return on equity along with money market debt costs. Telco capitalization is a mix of the two; it's all bundled into ROI calculations. The California PUC historically has given GTE (and the old PacTel) very low ROI, often a couple of percentage points or more below everybody else. When most states were allowing 13% and California was allowing 10%, which state would YOU invest in? To make matters worse, C-PUC would penalize GTE for its poor performance by lowering its ROI even more. AT&T was too proud of its "Bell System" reputation to let PacTel go down the tubes, so they dumped money into CA even with a cruddy rate of return. But GTE had other fish to fry with its cash, so they gave the state pretty much what it paid for. It looked bad, because it was bad, but it was a sound business decision. I don't know the current authorized ROI in CA, but I suspect it's higher, and GTE service should improve over time as a result. BTW this ties in to Steve Elias' distrust of DA charging. ALL such expenses are counted in computing rates. If telco saves money, it raises their ROI, which is made up for by lowering other rates (usually at the time of the next general rate case). They don't get to "keep" the savings. They still benefit but it's not the ripoff that the Mass. legislature pretends it is. fred ------------------------------ From: Na Choon Piaw Subject: Re: In Defense of GTE and their Apparatus Reply-To: Na Choon Piaw Organization: University of California, Berkeley Date: Sat, 16 Sep 89 00:58:48 GMT In article desnoyer@apple.com (Peter Desnoyers) writes: [...] >As a side note, I must say that the MIT dormline system is one of my most >favorable memories of MIT.

You may not be cetain why GTE is "singled out", but I think I understand. For year after year here in Durham I put up with : - noisy lines - wild buzzes and garbage, not just white noise and itsy, bitsy clicks now and then - picking up the phone to dial, only to find other people on the line in the middle of a conversation - getting chewed out at work, while on call, for not answering the phone to come in to do an emergency lung scan. The phone hardly ever rang when someone called me ... lots of people said "Where were you last night? I tried to call, but there was no answer." - "touch tone" that was not buffered well enough and was converted to pulse anyway (Dial "too fast" and you have to start all over.) - dropped connections in the middle of a conversation - wrongly routed calls (several times someone in other cities would have the operator to place a call to the Methodist retirement home, only to *still* have the equipment end up connecting to me) - wrong numbers, much more than I though was reasonable to expect. Why do I say that? Well, how can even the stupidest person continue to dial "8364" instead of "4082"? Wrong numbers were frequently not even remotely similar to my number. The list goes on, but you get the point I hope. And these were not isolated things every couple of months or so --- it was *all the freaking time*. I came very close several times to have the "service" disconnected and save the money and hassle. When I lived in Charlotte (Southern Bell), phone service was just that- a service. It was not a hassle and headache that someone charged you to have. SB was great. GTE _was_ a pain in the ass. To their credit, our exchange (383) was converted to ESS of some sort or other (all I ever heard was "its digital".), and all of the above kind of non-sense has stopped. GTE still charges for dmtf (about $1.50 / month I think). I refuse to pay them for something that is in my opinion to their benefit as much or more than mine to have. Why pay for subsidizing the pulse dial phone users when tone is more efficient from the standpoint of the switch? GTE has a rather large presence here in Durham, though some parts are being moved or have moved to other distant lands (Florida I think). I have several friends who work for GTE, but I never bothered to embarass them with all of the above. I'm sure they knew it all first hand anyway. Kim L.

We asked for some phone lines to be brought in digitally, but they have never heard of such a thing. We also have some lines coming from a distant CO, and they actually run them analog all the way from the home CO to us. This is probably 15 to 20 kilometers and the lines sound like it. Sometimes, when the lines ring, you pick up the phone and just keep hearing ring voltage in your ear and can not seize the line. The sound level is way low of course. There was an article in the Nihon Keizai Sinbun on 09/12 talking about this very subject. It was comparing all the wonderful features available in the U.S. to the dearth of services here. It also mentioned that no volume discounts are available here, even on the new toll-free 0120 service. We are also running into the problem that most buildings have very few available pairs from the CO. Most of the office buildings we have looked at renting space in have less than twenty pairs available.

PT] All US carriers charge the same rate to a foreign administration for carrying a call. This is a US regulation, and prevents problems when multiple providers have to deal with a single entity. There is no advantage to BT, or any others, to give a routing preference. Commonly, calls are routed in proportion to their receipt in the sending country, i.e. if 80% of the calls to BT come from AT&T, and 20% from MCI, than that same proportion will be preserved on the calls from BT. Collect, or credit card calls of course are routed to the owner of the account.

PT] I can guarantee that it won't be from BTI. As has been discussed, collect calls are billed by the TERMINATING carrier, at the TERMINATING carrier's rates. If you call collect using AT&T's USA-Direct service or MCI's Call USA service, the answer is obvious. If you place the call through the originating country's international operators, the answer is not so obvious. I had a discussion with the BTI operators last night about this. They say that they just put the number into their computer and have no influence over which carrier is chosen. What we therefore don't know is how the computer routes collect calls originating through the BTI operator. What happens is going to depend on the agreements for carrying traffic that BTI has signed with AT&T, MCI, and US Sprint. It is obviously merely a small matter of programming for the billing and routing mechanism to be interconnected in a fashion which allows proper billing from AT&T if the call came on an AT&T circuit, and so on. /john ------------------------------ From: portal!cup.portal.com!JDurand@apple.com Subject: Re: UK->USA, Which Carrier?

(I live in a town just southeast of Worcester.) However, in 1989 New England Telephone has most definintely taken notice of us. From April through August 1989, NET converted at least six or eight exchanges in the Blackstone Valley (towns south of Worcester) from SxS to ESS -- if that doesn't qualify as a breakneck pace, I don't know what does. This doesn't speak to the rest of Central and Western Mass., but where I live it has been astounding. There may well be much more conversion taking place; I am aware only of my local area, because NET places ads in the local papers explaining to people such concepts as seven-digit dialing for a month or two prior to the cutover.

Maine had 100 steppers, 71% of offices and almost a third of lines. That includes a lot of replacement work done in the past four years! Most of Worcester County is due for upgrade in 1990, though.

Please forgive the mention of specific names, but it simplifies the telling of the story. In 1914 (?) a young man named Fredrick E. Broderick went to work for MIT, which was at that time still located in Boston. By 1918, MIT had moved to its Cambridge location, and another young man, Carlton E. Tucker, graduated (his thesis was on the effects of air pressure on underground trolley car operation, bespeaking an interest in railroads and transit that lasted all his life). In addition to his interest in railroads, Carlton Tucker was very interested in telephones. During the next thirty years, he rose to full professorship in the MIT Electrical Engineering department, while simultaneously managing MIT's growing telephone systems. I say "systems" because there were two: one rented from New England Telephone, and an MIT-owned system. The MIT system consisted of a small 100-line SXS system that served the EE department (providing dial service long before the NET system went dial in 1941) and two manual switchboards, one in the graduate student residence (150 lines) and one in the East Campus dormitories (550 lines). The MIT system was maintained by Professor Tucker's friend Fred Broderick, who ran an instrument room in the EE department. In 1949, MIT built the first of the West Campus undergraduate dormitories, Baker House. New AECO SXS equipment (300 self-aligning plunger lineswitches, 30 first selectors and 30 connectors) was installed to provide a phone in every one of 250 rooms. In addition, when MIT purchased the nearby Riverbank Court residental hotel a few years later and converted it into Burton House / Connor Hall, 25 lines from Baker were run into that building to provide corridor telephones, each serving about 20 people. Lines from the Baker SXS system appeared at the Graduate House and East Campus manual boards (only about 4 lines each). The Baker System was fairly reliable, except that the lineswitches had a preference chain (of contacts) that often got dirty, resulting a loss of dial tone for up to 100 users. In addition, the dial tone generator was really a buzzer, and occasionally failed. Upon one such occasion, maintenance personnel replaced it with a tape "Dial Dammit, Dial Dammit". The Baker system was maintained by students supervised by Fred Broderick, beginning a tradition / fraternity that would last for 40 years, half of them under Broderick's direction. Sometime in the late 50's a student approached Professor Tucker with the idea of buying some surplus SXS equipment from a South Sea island location and fully automating the dormitory system, which at that time consisted of 100 SXS lines in the EE department, 300 SXS lines in Baker, and about 700 manual lines in Graduate House and East Campus. Professor Tucker explained to the student that the freight costs would be excessive, but the idea stuck in his mind. In about 1960, when Bob Clements and I were both Freshmen, the John Hancock Company equipment (3400 lines of AECO SXS) came on the market. According to one story, MIT dragged their feet about getting the equipment, and the "newest" equipment had been sold before Professor Tucker could convince MIT to pick up the remainder, about 2000 lines. Indeed, three of the 100-line groups that MIT purchased bore date stickers "1922". During the 1961-1962 period, Bob Clements and a couple others (from the original "WTBS" - the MIT station) put the equipment together, and he and I and others installed dial telephones in the rooms. On September 1, 1963, the system went completely dial, with roughly 1500 lines in service. The equipment was located in three separate locations spread over the campus, and included non-aligning and self-aligning plunger lineswitches (see Bob Clement's posting for the difference), linefinders, and lots of selectors and connectors. We had lots of variety. Some of the lines in the Graduate House were party lines with Tip Party / Ring Party selective ringing. Some of the connector switches were Trunk and Level Hunting, and were used for dormitory desks and student activities. Power systems included 70 ampere motor generator sets, large glass cased batteries, and the motor-driven Variac kludge that Peter Desnoyer mentioned. (The latter was given to us by NET. It used a Whetstone bridge circuit that compared the office battery to a reference battery. Current flow in the center of the bridge operated polar relays that flipped field capacitors in a 220V motor that operated the Variac. The Variac in turn regulated Tungar rectifier tubes.) Since this was 5 years before Carterphone, there was no connection to the outside world, and there was no operator. With the advent of Carterphone, various interconnection methods were employed, including one where the MIT operator (at the NET owned switchboard) used one cord set to set up the call and another (via a second jack) when the called party answered. Needless to say, disconnections were common. In 1976, the NET PBX (about 7000 lines of SXS) was replaced with a CO Centrex (1A ESS). Shortly thereafter, direct inward dialling was installed between the CO and Dormphone, permitting anyone in the world to call into 40-50 year old equipment. As Larry Lippman has pointed out, a good ear is an important maintenance tool, and it was easy to tell the difference between the slow and irregular dial pulse strings generated by Dormphone dials, and the crisp and rapid perfectly timed digits incoming from the ESS. Since MIT did not want to have to bill the students, all outgoing calls were credit card / collect / third party, and all incoming calls were greeted with a recorded message "This is MIT, collect and third party calls are not accepted at this number". The recorded message was stored digitally and was the highest tech thing ever to grace Dormphone. It was also the subject of several hacks, as people would break into the exchange and change the recording. During the late 70's and early 80's, additional dormitories were added to the West Campus, and equipment was purchased from American Optical and other sources, to bring the total number of lines in service up to about 2800. Meanwhile, the ancient equipment, including the 300 lines of 1922 equipment, continued to serve well past its 40 year design life, and remained in service until August 1988, when MIT installed a 5ESS purchased from AT&T. All of the Dormphone equipment was scrapped. Fred Broderick's name lives on amongst MIT students as a station at the Tech Model Railroad Club (recipient of a lot of Western Electric college gift equipment via Fred). Carlton Tucker's name also is immortalized in a TMRC station (he was the TMRC faculty advisor), and in a follow-on to his Wire Communications course, 6.311 Telephony. To me, Dormphone lives on as the most fun job I ever had. ------------------------------ Date: Thu, 14 Sep 89 23:29:27 -0700 From: "John R. Covert 15-Sep-1989 0204" Subject: Call Rates in the U.S. Clive Carmock (cca@cs.exeter.ac.uk) asks: >P.S. I would be interested to hear from anyone who could give me billing >example of the different call rates/times in the USA, and would be interested >to have details of the OFF PEAK LOCAL calls to residential customers - >ie; do you have to subscribe to a service to get these free? Things are incredibly complex here. Remember that we have hundreds (or is it thousands) of telephone companies, each with different rates. I'll present just a few examples. First, AT&T's rates for calls which originate in one state and terminate in a different state (as of 1 July 1989): Standard Rates: Mileage Initial Minute Additional Minutes Discount Periods 1-10 .18 .17 11-22 .21 .20 33% off Sun-Fri 5P-11P 23-55 .23 .22 56-124 .23 .22 48% off Every day 11P-8A 125-292 .23 .23 All day Saturday 293-430 .24 .23 Until 5P Sunday 431-925 .24 .24 926-3000 .25 .25 3001-4250 .31 .30 4251-5750 .33 .32 Note that we can call coast to coast for a maximum of 25 cents (about 15p) per minute (similar to the U.K. b rate, actually, but for a much longer distance). This is the end of the simple example. There are all sorts of discount plans that you can subscribe to which get you discounts on the above rates (and other companies have similar rates and similar discount plans). If your call is not crossing a state boundary, then the rates will be regulated by each of the fifty states. In Massachusetts, each carrier has two sets of rates, one set for calls that do not cross a LATA (local access and transport area) boundary, and another for calls which do cross the boundary. These are quite often drastically more expensive than AT&T's long haul rates. It costs me more to make a 1 minute call to a point in Massachusetts only 11 miles away than to call 3000 miles to Los Angeles. Additional minutes are lower, but a call to a point 86 or more miles away within my LATA in Massachusetts costs 55 cents for the first minute and 23 cents each additional minute, so more expensive no matter how long the call is than a call up to 460 miles away outside the state. The rates for local calls vary from town to town. There are places where all local calling is unlimited (for both residential and business customers), places where all businesses pay measured rates and all residences are unlimited, places where even residential customers cannot get unlimited rates, places where different rates for local calls are available depending on the chosen base rate, places where there is a per-call charge for unlimited duration, places where there are charges based on both distance and time within the "local" calling area, places where the rates for local calls are the same no matter what time of day, places where there are off-peak rates for local calls, and so on. The size of local calling areas varies drastically. From where I live, only a few of the adjacent towns are local calls, and one town which has a common border with our town is 19 cents for the first minute and 9 cents each addi- tional minute. Yet in Atlanta, the diameter of the local calling area is about sixty miles. There has been a lot of discussion of this in the archives, and if Patrick decides to publish them, I'm sure you'll get as many different examples of rates as there are readers of this digest. /john [Moderator's Note: As JC points out, the variety of rates just go on and on and on. Fifty states, each with a regulatory agency to set the rates within that state, a federal structure (FCC) for interstate calls; and some local community involvement in a few places. Typically, rates mile per mile are less expensive than for the same number of miles . Tariff and rate publications are large enough that they fill up entire rooms in telco accounting offices. PT] ------------------------------ Date: Fri, 15 Sep 89 20:59:52 EDT From: Gabe M Wiener Subject: Speaking of Strowger Organization: Columbia University They way I've always heard/read the story is that it was the competing mortician's WIFE who worked in the telephone office, and whenever the bereaved call would come in saying, "connect me to the undertaker," she'd naturally ring her husband's line. FYI, I don't know if this has been discussed already, but Strowger's original system did NOT use a telephone dial. It used three telegraph keys, and could only accommodate 999 phones. To place a call to, say station # 521, you'd press the first key five times, the second key twice, and the third key once. You would then wind the magneto, thereby causing the other party's telephone to ring. If the other number was busy, you woud NOT hear your own bell ring as you cranked, and thus you'd know you weren't getting through. Flashing the switch-hook would cause the selectors to reset, and cranking the magneto without dialing anything would raise the operator. The original strowger phones worked on a five wire system. One for talk, three for the keys, and a ground return. By the way, here's an interesting fact about the somewhat later Strowger telephone dials. They had 11 finger-holes. You had the usual 10 numerical holes, and then one marked "Long Distance." In actually, this extra hole did NOT send out 11 pulses as one might suspect. It sent out only 10, the same as dialing 0. Why did they have it? The researchers feared that the public would not be able to grasp the concept of using 0 both as a digit and as a way to call the operator! Gabe Wiener - Columbia Univ.

It IS catching on in many places. First, there is no capital outlay. It is one thing to go shopping, plunk down $100 (or more), bring the thing home and try to figure it out and hook it up, and worry about what happens when it breaks, and quite another to call "the phone company" and tell them you want their message service.

[Moderator's Note: This is a perfect example of why so many of us always opt when possible for 'centrex-like' features on our phones. For several years I had a small 'mini-PBX' in my home (a Melco 212, actually); a Demon dialer for speed-calling, and other attachments. Those things do not come inexpensively, and they do break down eventually. When you go centrex, you eliminate all the hassle. Starline service (Illinois Bell's home centrex service) gives me everything I had before for an extra $5.50 per line/month. No fuss, no bother, no maintainence. Why not go with central office answering equipment also? Makes sense to me.

Those three-line key telephones were the 575-series, and were made by AE, ITT, Stromberg-Carlson and Northern Electric (later called Northern Telecom). This "key system" (I use the term loosely) design was really the pits. There was no visual ringing indication, although using an external transformer one could wire the sets with lamp illumination for line use and hold. Hold was accomplished by bridging a couple-hundred ohm resistor across the line when the companion hold key was depressed (it LOCKED in place until released by the line key). Northern Electric had a small optional accessory unit which could be used with these sets; I don't remember exactly what it did, but it may have provided lamp flashing for a ringing indication. > The 356 ringback sounded like terminal flatulence. Some of the tone generators for older SxS, XY and Leich CO's used vibrating reed interrupters (like old car radio vibrators) instead of AC generator windings on a motor-driven ringing machine/interrupter. It sounds like the ringback tone (probably dial tone and busy tone, too) was generated in such a manner. > To call the neighboring communities of Saratoga and Campbell, you > dialed the seven digit number.

The second dial tone is rather unusual for a central office. I have seen a number of weird CO dialing schemes used by independent operating telephone companies, but have never run across one where there was actually a second dial tone - especially on a 9-level, which is strangely similar to that of a PABX. > Long distance was reached by dialing "112" plus the ten digit number. > An operator would ask for the number you were calling from.

Usually the DC open on the local loop which results in a signaling open toward the tandem that is long enough to release and reseize the tandem office is long enough to collapse the local switch train - thereby precluding this type of fraudulent call. Most people with "blue boxes" have plied their art through the use of 2,600 Hz SF tone to release and reseize a tandem office, thereby not affecting the local switch train. Blue box fraud was actually less common in areas using Automatic Electric apparatus since GTE/Lenkurt was usually used to supply the N-carrier and associated signaling. Most GTE/Lenkurt installations that I have seen utilized 3,700 Hz out-of-band signaling, thereby precluding the use of simulated SF tones to release and reseize a tandem office. > The standard phone issue was, er, well uh there was no standard phone > issue. It seems they used anything they could get. There were AE, > Kellog, Stromberg, you-name-it. This is a rather common characteristic of smaller independent operating telephone companies. There were several companies in the U.S. which sold refurbished 500-type sets for between $ 8 and $ 12 apiece, with no choice of vendor. Many independent telephone companies with tight budgets bought their telephones from these refurbishers, which was one reason for the variety. The variety of telephones was also confusing to IR (installation-repair) personnel; while WECO, Northern Electric (Telecom), and ITT telephones pretty much used the WECO wiring conventions, AE and Stromberg-Carlson were different from each other - and the rest of the world. These were in the days of non-modular telephones, so line and handset cords had to be replaced wire-by-wire, sometimes leading to confusion if one forgot to which terminal a particular wire connected. I once coined a term to describe this variety of telephone set vendors and models, and suggested to the owner of an independent telephone company that he place a sign in the business office announcing the "Telephone Du Jour". Strangely enough, though, he failed to see as much humor in this suggestion as I did. :-) > According to some of the GTE switchmen > I talked to later, the cable plant was in about the same shape.

One of the problems which results in this situation is that many independent operating telephone companies with 2,000 lines or less have no engineering personnel who can assure that cable plant and central office apparatus is installed according to generally accepted engineering practices. While times have been changing and there is now better formal education among plant personnel in smaller independent telephone companies, it is not uncommon to see technical operations of an independent telephone company planned and supervised by someone whose knowledge of telephony was largely self-taught or learned from a family member, with some additional experience from some short courses taught by vendors of telephone apparatus, and possibly from experience in the military. As a result of the above, much outside plant has been installed which may work for POTS service, but which is less than optimal for carrier, data or radio program circuits. Improperly changing gauges of cable and failing to install the proper loading coils at the proper spacing will result in cable which simply cannot be adequately equalized or repeatered using the balance and build-out networks in off-the-shelf apparatus. The problem is that the personnel responsible for the original cable installations simply didn't know any better, later resulting in a situation that is very expensive to correct. Once upon a time I was speaking to the owner, and, um, "plant superintendent" of a small telephone company about the transmission on his intertoll trunks to a Class 4 office. This fellow had a rather profound regional accent, and could probably understand me on an equally poor basis. A real puzzled look came across his face when I started talking about VNL (Via Net Loss). He finally interrupted me and thought I had changed the subject and was taking about venereal disease! While he did know something about veneral disease, he knew nothing about VNL - which I guess proves my point about lack of engineering skills in smaller independent telephone companies. :-) <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: John Higdon Subject: Pac*Bell: The Old Bell System? Date: 16 Sep 89 20:02:41 GMT Organization: Green Hills and Cows Over the past months, a number of disturbing manuvers have been executed by Pacific Telesis. It would appear that in direct contradiction to the spirit of Judge Greene's order, our RBOC is trying to re-create the old Bell System. In the past year, Pacific Telesis has attempted or received approval from appropriate agencies to provide the following: Voice Mail Cable TV Service VideoTex AudioTex InterLATA Long Distance Service Telephone Equipment Vending In short, it looks like a major attempt to become a one-stop telecommunications shop once again. Some items to consider: Pac*Bell has finally obtained its long-sought ability to arbitrarily disconnect 976 providers. In a recent federal court decision, Pac*Bell was told that it could disconnect any provider that had "obscene" material. The determination of "obscene" is, of course, left in the hands of none other than Pac*Bell. It doesn't take much imagination to see what a tremendous advantage that would give Pac*Bell in the AudioTex field. It would be "obscene" if some competitor was taking away busines from PB, ergo turn him off! We're already seeing what control of the network can do for a promotional effort. When I was in the equipment vending business, it was quite common for PB to contact one of my customers and darkly imply that if they got their equipment from "the phone company", that their service would improve substantially. A friend of mine, who is currently in the equipment business, has documented proof that PB is perpetually causing trouble on a customer's trunk. He reports trouble, they clear it, and the next day it's bad again. When, on behalf of his customer, he asked someone at PB what all the trouble was, he was told that "there seemed to be cronic trouble with the CPE". That was followed with a well-timed call by a Pac*Bell rep who raved about the virtues of Centrex to the customer's telephone administrator. Of course there had been no trouble with the CPE; if there had there would have been major charges levied by Pac*Bell. This Thursday, there will be a discussion by industry players on the matter of Pac*Bell's entry into the VideoTex field at the State building in San Francisco. Yours truly will certainly be there watching the PUC, Pac*Bell, and videotex providers battle it out. John Higdon | P. O.

If you travel anywhere outside of any hard-core metro area, you will find old-timey CO equipment being operated by Pac*Bell. Even in the metro areas, crossbar is still the order of the day. San Jose, California's third largest city, *still* has about twenty prefixes served by #5 crossbar, and quite a few prefixes served by ESS offices running an obsolete generic. In the nearby Santa Cruz mountains they are running SXS as they are in many other areas of the state. John Higdon | P. O. Box 7648 | +1 408 723 1395 john@zygot.ati.com | San Jose, CA 95150 | M o o ! [Moderator's Note: Years ago people were saying how very progressive Illinois Bell was, relative to her sisters. I think it was true. We were among the first places to be equipped with 911; we had centrex service in several large organizations (Chicago Tribune, City of Chicago, and Amoco Credit Card, to name just three) in the middle 1960's -- on crossbar yet, as was our first 911; our downtown and near north side were ESS as of 1973-74; and over a nine year period Chicago was completely converted to ESS. We in the outlying areas finally cut over about 1984. Historical trivia: The City of Chicago offices operated on a seven position cord board (RAndolph 6-8000) for fifty years. Police emergency was translated by each CO from POlice 5-1313 to some other number at police HQ. The police administrative number was WAbash 2-4747. In about 1963 when all city offices were scheduled for cutover to centrex, some wit at telco who was a bit of a radical in the radical 1960's when police were unkindly referred to as 'pigs' said people should dial P-I-G to reach them. It so happens the 744 prefix was *not* in use, and as a lark, that person maneuvered to have that prefix assigned to the new City of Chicago centrex. So now to reach the main number for City Hall, we can dial 312-PIG-4000. Or to reach any certain police officer, dial PIG and the desired four digit extension. :) PT] ------------------------------ End of TELECOM Digest V9 #380 *****************************   Date: Sun, 17 Sep 89 5:16:15 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #381 Message-ID: <8909170516.aa01406@delta.eecs.nwu.edu> TELECOM Digest Sun, 17 Sep 89 05:00:58 CDT Volume 9 : Issue 381 Today's Topics: Moderator: Patrick Townson Starline Service From Illinois Bell (TELECOM Moderator) Re: In Defense of GTE and their Apparatus (John Higdon) ---------------------------------------------------------------------- Date: Sun, 17 Sep 89 4:58:01 CDT From: TELECOM Moderator Subject: Starline Service From Illinois Bell A while back, a reader in Australia asked for more information about home centrex service here in the United States. In some places, this service is called 'Intellidial', and in other places, such as Chicago, it is known as 'Starline'. There may be other names for it in other communities. In most cases, the features are the same. Here are the basics -- You have between two and six incoming lines from the CO, as you desire, based on your needs. (I have two.) Each line has its own number, just as you would probably have anyway. In Chicago at least, all (both) numbers must be on the same prefix, or exchange. In my case, this is 312-743. In addition to the usual 'custom calling' features available, such as call waiting, three way calling, call forwarding and speed dialing, several other options are available, as well as some enhancements on the first four. Each phone on your premises can be reached two ways: 1) In the usual method, by a caller dialing the seven digit number. 2) As an intercom from all other lines on your premises, by dialing the intercom code, which is 2# through 7#, as assigned. There is no charge for intercom calls. Make as many as you like. Intercom calls can be distinquished from CO calls by the ring. CO calls to the line cause a short, double ring-ring (pause) ring-ring sound. Intercom calls cause the 'normal' ring-pause-ring-pause sound. This enables the person receiving the call to use the appropriate answer phrase. Intercom calls do busy out the line, however call-waiting eliminates any problems here. Both the CO and an intercom call can camp-on with call-waiting tone to another line which is in use. As in conventional call-waiting, just one camp-on is allowed. Another feature is call pickup. Any call can be answered from any line. If the call is coming into the line you pick up, then just respond as usual. If the call is coming into some other line, then dial *9 and the ringing call will be automatically transferred to your line instead. Call holding is available. You would want to hold a call for various reasons; such as to answer a call-waiting on the line you are presently using, or to pickup a call ringing on another line on your premises. You might wish to simply put a call on hold while doing something else, or to go to another phone to continue the conversation. To hold a call, flash, then dial *8. If a call waiting is on the line, it will automatically be handed to you at that time. To go back and forth between the calls-waiting, just flash and dial *8. You will alternate between calls as desired. If a call is ringing in on another phone in your group, you would flash, then dial *8 (to put your call on hold) then *9 to answer the other line. At that point, both calls are treated like calls-waiting, and flashing, followed by *8 alternates between them. To simply leave a call on hold while you are engaged elsewhere, flash and dial *8, then abandon the line, leaving the phone off-hook. The new dial tone will time out after about fifteen seconds. To return to the call, replace the receiver for a second, and answer when the phone rings. To pick up the call from some other line, hang up the first phone, go to the desired phone and use *9 to retrieve the call left ringing elsewhere. Three way calling is also enhanced by Starline. Under ordinary custom calling, a three way call *cannot* be started when call-waiting is in use, since the former requires a switchhook flash, and if a call is waiting, the flash will simply bring up the other call. Using the Starline 'flash, star 8' approach, three way calling becomes possible. In addition, under ordinary custom calling, you must be the originator of at least one of the three sides to the conversation, and must remain on the line at all times during the three-way call. This is not so in Starline. Here is an example: I'm on a call, and get a call-waiting. I flash, dial *8 and take the second call. I alternate between them. On one of the two incoming calls, I wish for the caller to speak with my brother in his bedroom. I flash, dial his 'extension' (or intercom code, really, which is 2#), and when he answers, I announce the call and hang up. Now, that call is gone from me. My phone rings again, and the call I left on the other side of the call-waiting is back with me again. As another example, I place or receive a call. The other party wants to talk with a third person, but does not know his number. I flash, dial the third number, announce the call and then *disconnect*. Those two parties will remain connected, and I will drop out of the call -- and free my line -- just as in 'regular centrex'. If you have two calls on the line, the one on the 'top of the stack' is the one to be affected by a transfer to another line in or out of your group. You manipulate, or 'pop the stack' to get whichever caller you want on top for the purpose of transferring, etc. In other words, the one I am talking to now (or have most recently put on hold) is the one who gets transferred; while the other one waits for my return. If you are not talking to the 'right one' for this purpose, then flash, dial *8 and bring around the one you want prior to again flashing and transferring. Ordinary phone systems can usually 'hunt' in rotary for a free line. I had this feature for years. If my first line was busy, the call would be put on my second line, unless it was also busy, in which case busy would be returned to the caller. Under Starline, some enhancements are available: 'Circular hunt' allows any line in the group to hunt to some other line. My first can hunt the second, and the second can hunt the first. The six lines maximum in a Starline group can go around hunting each other as programmed. Backward or foreward does not matter. 'Transfer on busy/no answer' starts the hunt process not only if the called line is busy, but also if it does not answer after three rings. The 'busy' part of this scenario only applies if the call-waiting is also engaged on the line in question, or if there is dialing in progress (call waiting never occurs when you are dialing, as it might interefere with the dialing process). So if your line is 'truly busy' by CO standards for same, then the hunt process begins. Since we use *70 to 'suspend call-waiting' for the duration of the call in progress, this also forces a busy condition on the line should a new call arrive (and have to hunt elsewhere). 'Suspend call-waiting', or *70 as a prefix to whatever else you dial, has long been a standard custom calling feature here except in a couple of offices with older generics. This feature is used for those 'very important calls' which you do not want disturbed, and for modem calls, where a call-waiting signal would interfere with the data. Call Forwarding is enhanced under Starline. It operates as expected, but does NOT forward intercom calls if the place forwarded to is outside your group. It DOES forward intercom calls as well if the forwarding is to another phone in your group. You can forward in or out of group as desired. The exceptions are you cannot forward to 411,611,911, any 555-1212, 976 or 900+anything. Nor can you forward to 950 or a long distance number *on other than your default carrier*. Call Forwarding takes precedence over call-waiting from a phone outside your group, but not from an intercom call, unless the forwarding is within your group. Here is another example: Station A hunts to station B on 'busy/no answer'. Station B has call forwarding turned on to some place outside the group. A is busy and gets a CO call, so it hunts to B. The call will forward to wherever B is being sent. On the other hand, A is not busy, but there is no answer. Since B is being forwarded, the call to A just continues to keep ringing on A, since there is no reason to assume A would want his calls answered by some out of group place where B calls are going. I realize this is not entirely logical (to forward via B if A is busy, but not forward via B if A is unanswered) but that is the way they have it set up. I think they would change it for me if I asked, but that is another part of the story. Convenience Dialing is known as 'speed calling' in many places. Under Starline, you get a thirty number repretoire, which are dialed as *20 through *49. Any number in the world, dialable from your phone, including international calls, can be programmed into the 'speed dial'. It is programmed from any line in the group, and can be accessed from any line in the group. They tell me there is a method of partitioning it, with certain speed dial abbreviations going to one line, some to another, etc... but mine is set up so all speed dial numbers can be accessed from all lines. Only one programming is required; what you program on one line works from all the others. In summary, Starline gives me tremendous and virtually complete control over my phones. A new feature being made available in the next few months is a form of call identification which allows up to three CO numbers to be assigned to one line. Variations in the ringing pattern advise which CO line was dialed. This permits various users of the same line to know ahead of time who is being called. In my case, I'll have my 800 number assigned to a new CO number, which will ring two short/pause/one long to tell me I'm paying for the next call I receive. Not peculiar to Starline, but available from Illinois Bell is consolidated billing. Unit charges and toll charges from all lines in the Starline group are accumulated as a total where discount volume rates would apply. For example, since we here must pay for local calls -- but there is a discount in pricing after a certain number -- all calls from both my lines are tallied together to count toward the total required. My Reach Out America plan can be used from either line with just one monthly fee to AT&T. The monthly billing does itemize which long distance calls went out/came in on each line, but the total of all is used toward monthly purchase requirments. The bill will have a section entitled, "Calls from 743-xxxx" with those calls which specifically originated (or were received collect on) any line other than the main billing number. A collect call to my second line will show up on the bill charged to the second line *for the entire duration of the call* even though I may have 'pulled the call' when it came in to my first line via *9. Likewise, any outgoing calls are billed in their entirety to the line they were dialed out on, even though in mid-conversation I may switch to another extension to continue, or indeed, even transfer the call out of my system entirely via three way calling and disconnect myself. Starline users get a little manual, or instruction book to use (are you surprised?), but after a few days it all becomes very easy to remember. I think the CO installers are the ones who need the lessons, however. To get Starline turned on is a challenge. At least it was when I first started using it two years ago. I put in the order with the business office and was told it would be on within two days. A week was more like it. At least four different people fiddled around with it before they could get it right. Each person said they 'had it working okay' and the results on my end were different (and wrong!) each time. I put the order in on Monday. They started trying to get it working on Wednesday. For four days my phones were screwed up. Finally, after I made a real stink Saturday afternoon with Repair Service, I got a call back Sunday morning at 8 AM no less, from a woman who said "I am going to be here (in the CO) all day with my husband, and one or the other of us will have it going correctly for you by this afternoon. I personally will call you, or he will, when the job is finished." Yeah sure, I thought. But true to her word, about 11 AM she called me and said let's go through all of it together and see if it is doing what you want it to do now. And sure enough, it was fine, and has been since. The next morning, the business office manager called me, "ooooh, Mr. Townson, I dooooo hope we have gotten your system in order finally....and with your permission I will show today as the starting date for billing purposes." My total monthly bill for local service is as follows: Non-pub directory service 1.45 (covers both lines) Two touch tone services 1.46 (.73 each for two CO lines) Two line charges 9.06 (4.53 each for two CO lines) Two Starline packages 11.04 (5.52 each for two CO lines) One Call Waiting 2.50 (I took it off my modem line entirely) One Convenience Dialing 5.00 (32 number speed dialing for entire group) One Call Forwarding 2.50 (only on modem line, not first line) Total Local Service 33.01 Then I pay about 4 cents per 'unit' and long distance rates as applicable.

The McCullough Loop works by running a huge series circuit, which begins and ends in the alarm company central station, through each and every alarm customer location, While there is only a single pair which enters a customer premises, the wires should be visualized more as "in" and "out" rather than "tip" and "ring". The combined resistance of a closed (i.e., no customer sending a signal) McCullough Loop might be several thousand ohms. The alarm company central station excited the loop with 130 volts DC, and used a sensitive relay to detect current flow. Each customer location had a NcCullough "transmitter" which consists of a motor-driven code wheel, which when operating sequentially opens the loop and shorts it to ground. Each customer for each alarm (a customer could have more than one alarm) had a transmitter with a uniquely-coded code wheel, which resulted in a signal not unlike that of Morse Code. The alarm company central station was equipped with a "pen register" which drew lines on moving paper tape to display the code. The design of this pen register can be traced back to before 1850 - the era of Samuel F. B. Morse! When an alarm customer sent a signal, the initial open of the McCullough Loop operated an audible alarm at the alarm company central station, where an attendant would go over to the pen register and attempt to decode the signal. While this was rather crude, it worked well except for one situation - where TWO or more customers were simultaneously sending signals! Since 50 or more customers could be on a given McCullough Loop, this was not uncommon - especially at common times in the morning and evening when customers with intrusion alarms would automatically report "openings and closings". A particular problem arose when the McCullough Loop would go open due to a cable problem. In some cases certain customers would still have alarm protection since the transmitter also shorted the loop to ground, and the alarm company apparatus was also equipped to detect this condition. However, other customers might be totally without protection. It was generally not possible for the alarm company to know where a loop open had occurred, so they immediately called the telephone company, who would in turn dispatch a repairperson to a suspected CO to check each pair from the CO on trial-and-error basis. It was also easy for a burglar with technical knowledge to defeat the target alarm system by first shorting the McCullough loop at a utility pole, and then opening the pair to the subscriber premises. The apparatus at the alarm company central station could never detect this condition, and more than one burglary was effected in this manner without anyone being the wiser - until it was too late. This weakness was never countered until the late 1960's when electronic Loop Integrity Devices were available. The Loop Integrity Device was installed at customer locations willing to pay for this additional security. In operation, added apparatus in the alarm company central station would send a low-speed coded interrogation signal with a unique address for each Loop Integrity Device, superimposed on the normal McCullough Loop current. Since this was DC signaling, the speed was 50 baud or less. When the Loop Integrity Device recognized its address, it would momentarily open its loop as an acknowledgement to the alarm company system. Polling would be interrupted upon receipt of an alarm signal. The Loop Integrity Device was only of limited benefit, since an open loop due to cable failure (accidental or "otherwise") still put some customers out of service. Most McCullough Loop systems have now been replaced with apparatus that uses bridged data lines (so that a short on one subscriber loop will not affect other subscribers) with frequency-shift keying of two-way digital data. The newer systems also allow one alarm unit at a customer location to send a number of individual signals to indicate different alarm conditions. > Today several vendors have T-CXR channel units > for this service, but it is still a basic series [just like old > Christmas tree lights] circuit that causes the Telco nightmares when > the circuit goes open. It was also an annoyance for customers.

The 43A1 voice frequency carrier data system system was developed in the early 1950's to replace the 40C2 system, which was developed around 1930. While the 43A1 also added 8 channels in the above-voice frequency range of ~3,500 to ~5,000 Hz, the basic 17 channels from 425 to 3,145 Hz were compatible with the earlier 40C2 system. The 40C2 system, which used rather large vacuum tubes (with grid caps, no less!) was a monster where ONE channel occupied about 16 inches of rack space. I saw 40C2 in service during the 1960's, but I am certain that it is all gone by now. The 43A1 system used miniature vacuum tubes and plug-in modules, and then allowed three channels to occupy about 14 inches of rack space. I feel certain that there is still 43A1 in service, but it must be getting scarce by now. The 43A1 system was replaced by the 43B1 system in the late 1960's. The 43B1 finally used transistors, and all 17 channels could fit in less than 36 inches of rack space. The 43B1 was compatible with all channels in the 43A1 system. I am not aware of any WECO apparatus newer than the 43B1, and it is entirely possible that nothing has replaced it since the 43-type system is, by its very nature, doomed to a now rapid obsolescence. The 43-type system has primarily been used for two purposes: low speed (150 baud and less) telegraph channels for baudot telex service and private line teletypewriter service, and for telemetering and control circuits as used by utility and pipeline companies. Both of these applications are changing, however. International telex is going to higher speed ASCII terminals which work at 1,200 baud or more - at least in the U.S. where the international ASCII <--> baudot conversion is performed at the U.S. switching center of the telex carrier. Utility and pipeline companies are migrating toward process computer-to-computer communication which can handle numerous data and control points with a single high speed data channel. However, there is still a large number of 43-type compatible systems in service for the utility and pipeline industry, especially on private microwave radio links. Since actually little WECO apparatus has been sold to these industries, most of the apparatus is made by such vendors as RFL Industries, GTE/Lenkurt, etc. and is functionally compatible with the 43-type system, but is physically different. > Another common data application was the dumb terminal to host > connection, used mainly with time share systems. Connections were > typically 300 baud, and the modems were much bigger than a bread box. > Connections were available in two flavors, dial-up and private line. Data sets for 1,800 bps and below which employed the switched network or private lines all operated on frequency-shift keying, and all dealt with bit-serial data. Well, there was an interesting type of data set - now long since obsolete - which operated as a _parallel_ data set; i.e., it sent data as _characters_ formed by sending simultaneous tones. These data sets fell into two categories, the 401-series which could transmit data at a maximum rate of 20 chars/sec, and the 402-series which could transmit data at a maximum rate of 75 chars/sec. Up to three simultaneous tones could be transmitted. The tones were divided into three groups. The "A" group had four tones which were exactly the same frequencies as the 4x4 matrix DTMF Low Group tones. The "B" group had four tones which were exactly the same frequencies as the 4x4 matrix DTMF High Group tones. The "C" group had three frequencies which were higher than the "B" group. Some versions of these data sets only used the "A" and "B" group tones so that the data sets were effectively compatible with conventional DTMF signaling with a 4x4 matrix. There were also three additional tones, which were optional, and were assigned as "idle" tones for the "A", "B" and "C" group. A common application of these data sets during the 1960's and early 1970's was a direct interface to unit record equipment for sending data encoded in Hollerith character format.

Twenty years ago I could >rent< a PABX from one and one only vendor: New York Telephone, and I could have a choice of anything I wanted as long as it was: * 507B "cordless" manual board with 5 trunks and 20 lines; a 1950 version of 1920 technology * 556 cord board; a 1945 version of 1920 technology having "modular construction" * 608 cord board; a 1960 version of 1920 technology having new-fangled features of "automatic ring and attendant flash" * 701 and related (710, 711, 740, etc.) SxS PABX's; required dedicating a WHOLE ROOM to the telephone company * 756 dial PABX; maximum of 80 lines, size of two household refrigerators * 757 dial PABX; maximum of 200 lines, full-featured version with maximum number of lines occupying size of EIGHT household refrigerators * 20/40 Dial Pak; the worst excuse for a PABX ever conceived, with the possible exception of the 755 (which was so useless that it was already discontinued) Of the dial PABX's above, DTMF service was technically available, but was non-tariffed and considered a "special assembly" by New York Telephone, and was not provided unless one's organization was a Very Important Customer. :-) The 558 >manual< PBX using Moden Crossbar Technology was not yet offered in 1969, nor was the 770 crossbar PABX, or the electronic crossbar PABX's like the 805, 811 or 812. The original Dimension PABX (now quite obsolete), were it described in 1969 would seem like something out of a Buck Rogers movie. The Carterfone Decision and the birth of the interconnect industry certainly sparked a revolution in telecommunication technology at the PABX and station level. I shudder to think about how far station and PABX technology would have advanced had there been no Carterfone Decision. My organization has four separate facilities, and in July we had a local interconnect company install a Northern Telecom Meridian SL-1 to serve about 100 extensions in two buildings about 1/4 mile apart (we have our own UG cable between the buildings). The SL-1 replaced a badly aging Tele-Resources electronic PABX which was losing about one call in ten. The SL-1, complete with voice mail and auto-attendant features and equipped for 100 lines is about the size of a four-drawer file cabinet. Almost all of our stations are electronic sets, some of which have LCD alphanumeric displays. This SL-1 is so sophisticated and so different from the technology at the time when I had firsthand experience in the telecommunications industry that it boggles my mind beyond belief. The SL-1 is more of a computer than a PABX in the traditional sense of the word. Also, since there is there is absolutely no way to "tinker" with it :-), unlike PABX's of previous generations, I have nothing to do with its administration other than to make certain that some system-wide features get set up correctly by the interconnect company.

Interesting that neighboring areas > served by Pacific Telephone didn't have those problems. For the past few days I have been trying to determine how to respond to your statements, and until today have been at a loss for words. I admit that I have had no firsthand experience with GTE in California, but I have had considerable experience with GTE elsewhere, and I have known a number of people in both the GTE manufacturing organizations and in their operating telephone companies. What you relate is simply contrary to what I have personally experienced. Its sounds like GTE has let their CO apparatus go to hell in the proverbial handbasket. I will defend to my death that SxS apparatus, while hardly state-of-the-art, is actually rather reliable - PROVIDED that it has been cleaned, oiled, routined and otherwise maintained. It sounds like such maintenance was simply not performed, which indicates some serious lack of CO personnel and serious lack of responsible management for a telephone company. The apparatus will indeed do the job - but in the situations which you describe it is PEOPLE who have let the apparatus down and caused these service problems. Now, the burning question is how could GTE allow this to happen in California? The most reasonable answer just appeared in telecom article by goldstein@delni.enet.dec.com, and boils down to not having enough revenue to operate a telephone company in a reasonable manner. $> The California PUC historically has given GTE (and the old PacTel) $> very low ROI, often a couple of percentage points or more below $> everybody else.

Actually, most central offices are designed with an overall grade of service between .01 and .001. This means that it is "acceptable" for between 1-call-in-100 and 1-call-in-1000 being lost due to equipment failure or trunk blockage. Prior to ESS, a .01 grade of service was not uncommon. So, your apparent grade of service was .2; it could have been a .3, and therefore worse. :-) > When they installed their highly-touted 1EAX we were all told, as Mr. > Lippman pointed out, that this equipment was more advanced than the ESS > being used by Bell in the surrounding areas.

I have seen the No. 1 EAX, and it is not junk. I don't know why there was trouble in this particular office, unless it was a very early machine (say, before 1974). Part of the problem may be the CO personnel being inadequately trained. ESS has been a real culture shock for older SxS switchmen who have learned their trade solely through on-the-job experience. It is pretty difficult to teach the use of an oscilloscope to someone whose principal troubleshooting tools have been a test lamp and test receiver for the past 25 years. I have personally seen a case where an "older generation" SxS switchman destroyed half the MF receivers and all of the spare boards in a CO because he was trying to examine TTL levels with a test lamp, one side of which was connected to -48 volts! Despite what appeared to be adequate training, this fellow really never understood what he was doing. > Glossary term for the day: > subscriber carrier; GTE's answer to undercapitalization The Bell System has also used subscriber line carrier of the lowest quality - the infamous Superior/Continental AML. This subscriber line carrier provides no bridged ringing (ringing is brought out on a third wire), and offers an on-hook loop voltage to the subscriber station of a whole 6 volts (less, if the battery ain't charged). Needless to say, such subscriber line carrier at best can operate a 500-type set, and nothing else. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Sun, 17 Sep 89 13:21:12 mdt From: "J.

On a second occasion I was able to find it again, but I cannot recall the exact address. I know very little about the Chicago area, but remember this much: it was less than 10 minutes away from the first block of S. Franklin St. and may have been located on Madison or Monroe St. (but I am not certain).

Either that, or an answering machine. PT] Or just let the damn phone ring. I installed the telephone for my convenience; when it is inconvenient to answer it, I don't. I often don't answer my front door either. Around here, most people who come to my door without appointment are either selling candy or religion, and they've clearly already ignored my "no soliciting" sign. Only my own overinflated respect for human life and the law keeps me from killing them on the spot and relieving the world of yet another pest. If there were a "kill calling party" button on your phone.... An interesting exercise: put a scorepad next to your phone. Each time you answer an incoming call, put a check in either the column "important" or "not important" (perhaps "worth answering" or "not worth answering" would be better categories). At the end of a month or so, count up the checks and you'll have some statistical basis for the "but it might be important" argument for your almost-Pavlovian response to a ringing phone. If the bell annoys you, stuff cotton into it so that it's a pleasant and unobtrusive sound.

Read on... > What we need for telephones are the > moral equivalent of the "No soliciting" signs many apartment complexes have. I don't know about moral equivalent, but I can suggest the practical equivalent. Callers who dial my listed number are all confronted with my machine. It offers callers three choices: 1. Leave a message, 2. Page me on my beeper, or 3. Force the call through to The-Real-Me. There is no default; if no DTMF digit is entered the system hangs up after 30 seconds. For the page and call-through options, there are appropriate warnings about misuse. In the two years that I have had this system, I can't recall being paged unnecessarily. Solicitors that "come through" have been warned about solicitation, so it's very easy to hang up on them. No automatic solicitation machine can get through (but who knows what the next generation may bring:-). My greeting recording changes according to the time of day, changing the options when I really don't want to be disturbed. With two years of experience, I can tell you that the system works. Now I'll answer your flames in advance. Callers without DTMF can't get through. I don't know of anyone I wish to speak to that doesn't have a touchtone phone. It's not cheap. A Watson and the host computer will set you back at least $1,500 (but if you have an old XT with at least a 20 meg drive, this could be new life for it.) On the "have not" to "have" scale, I would put this solution somewhere between "using a machine" and "hiring a butler". Remember, my first choice would be to have a butler:-) In addition, I have an electronic key set mounted next to the porcelain convenience that can access all necessary lines (soon the front door, also) just to be prepared for all eventualities.

I have heard stories of people with Telebit TrailBlazers who have picked up a phone on the same line as the modem, while it was on line. They heard a lot of screaching, but the modem didn't miss a beat.

Chin: I noticed your question about CFU and CCBS, and an article by Mr. S. J. Chin. I forwarded a copy of your message to Mr. Chin, who happens to work (somewhere!!) in this building. His reply, in part, is as follows: I'm no longer working on feature interactions. To answer the specific questions below: - why CFU overrides CCBS: the 2 features are incompatible, ie cannot be activated at the same time, so one has to give way, and CFU having precedence over CCBS makes for simpler interactions and/or more 'rational' operation from the users perspective (eg the U in CFU stands for Unconditional, ie the user would expect to be able to activate the feature irrespective of any outstanding CCBS, etc). ..... swee-joo ... Daniel Zlatin ========================== My comment: Why does CFU having precedence over CCBS makes for simpler interactions ? ========================== The second reply: Someone else responsed that the reason why a subscriber wanted to invoke CFU is because he might not want to be disturbed at that particular number. >My question is why withdraw the scanning ? Why not bar the user who is >being scanned from activating CFU ? A decision based on the user's perspective. If I'm setting CFU, it's because I don't want to be disturbed. Unconditionally (hence the 'U'). .... J. Deters - jad@dayton.DHDSC.MN.ORG john@jaded.DHDSC.MN.ORG ========================== My comment: There are however other reasons why a subscriber might want to invoke CFU. For example he might want to move to a new location and do not want to miss important calls. If the subscriber did not want to be disturbed then why not set up call blocking instead ? The setting of CFU could be that the subscriber do not want to be distributed but still wants to record important calls and so have all future calls forwarded to and answering machine. If that's the case then why not have the CCBS scanning transferred to the forwarded number ?

Not if you SCREEN calls with the machine. The idea being here that you turn the volume up on the machine enough to hear it from where you normally are. Then you simply LISTEN to the incoming call. The person calling you identifies themselves after the beep, you hear them, and if you like the sound of the caller's voice THEN you are interrupted -- and pick up the phone. The machine that I have (and I suspect most modern ones as well) will drop off the line if I pick up any extension in the house during a call. Thus I can either (1) be interrupted and pick up the phone immediately, (2) let the call time out in 4 rings and allow the machine to get it, THEN decide whether or not to pick up after the person identifies themselves, or (3) let the machine take a message and call the person back later (if I want to). Maximum choice, minimum hassle. Works great if I am on the pot too -- the machine takes the call, and I can call back when I get done using the toilet or showering or whatever. >There is a real and significant difference between junk mail and junk calls >that Karl doesn't seem to understand. I can deal with junk mail at my >leisure. I cannot do that with telephone calls. The telephone interrupts >me. The telephone does not have to interrupt you. You can mask the interrupt in one of three ways: 1) Turn off the ringer. Then no one can get through to you except when you want to be interrupted (by turning on the ringer again). This has the undesirable effect that if someone you want to interrupt you calls, they can't reach you either. Such is (one) price of privacy. 2) Use an answering machine to screen the calls. This means you get to hear who it is on the other end BEFORE you pick up the phone. This has lots of advantages over even Caller*ID -- caller id gives you a number, but doesn't necessarily identify the >caller<, which is the purpose of this exercise. The machine does, since you get to hear a voice first. Finally, a Caller*ID number display may not guarantee you a return phone call path, as some lines are (on ESS switches) configured for outgoing calls only. There is a further advantage -- most telemarketers hang up when they get a machine, so in many cases all you hear is "ring ring ring ..... !" Since I have started doing this I have not had to answer "junk call", yet all my friends and relatives still manage to get through.... seems as though it solves the problem to me! 3) Ignore the ringer when you don't want to be bothered. Why do you have to answer something just because it is beeping for your attention? I certainly am not compelled to pick up the phone when it rings -- I do it by choice. >I refuse to screen all my calls with an answering machine because of >the problem stated above.

Why prohibit anything? Is having a telephone, and a silent one at that, a God-given right? I think not. You have several means at your disposal to deal with the problem. When you have telephone service installed you implicitly, by having an incoming number, make it possible for me to dial it. If the possibility of that phone ringing bothers you, then deal with it. Instead of taking responsibility for your own choices and results, you (and lots of other people) want the government to do it for you. Feh.

I respond in a hurried voice, telling them that I got their call on call-waiting, while on a long distance call. If they ask, "Is this Mr. Cook?", I say, "No, he's dead!", and hang up. I got the idea after answering calls at my folk's house after my dad died :( If I am in my ham radio room in the basement, I tune in some weird sounding howling signal on shortwave (Radioteletype is nice!) and gradually increase the volume, acting distracted and unresponsive. When they ask what is going on, I tell them that I am receving some messages from overseas operatives, and they have called at a bad time. My favorite is when the long distance carriers call. I tell them that I recently did a comparison of their carrier with the one I currently subscribe to by using 10XXX codes, and that their bit-error rate and call setup time are unacceptable. They don't really want to get into a discussion of nuts and bolts technical aspects of the system, and they go away real quick. Another way to deal with solictors is to listen to the spiel, and tell them flat-out that I am not going to buy. Oh yeah....I just remembered another cute ploy....

(It used to be called Premiere 2/6.) Instead of 6 lines, Commstar II has 30 line capability with intercoms numbered #20 thru #49 (I have 8 in mine). The trade-off, which I hated until I needed to add those 2 extra lines:-), is that speed calling is only 6 numbers (how useful) and is individually programmed on each line as opposed to being programmed system-wide from the "main" line. Speed numbers are accessed with *2 thru *7. Since *7 is a valid beginning to other features such as cancel call waiting and forwarding, etc., when you call the *7 entry you either wait six extra seconds or hit # (*7#). The other difference is that *8 is used for call pick-up, while *9 is used for hold/call waiting. Your explanation of how they screwed up your order I think must be written into the Bellcore spec for the offering. Every time (and I mean every time) I have placed the simplest change order or have ordered new service in conjunction with my Commstar II, it has been a circus, wherein they either botch the order itself and I don't get what I want, or the bill makes Fantasy Island look like sober truth.

(David Lewis) ---------------------------------------------------------------------- Date: Sun, 17 Sep 89 21:09:14 CDT From: TELECOM Moderator Subject: Western Union: Telex, TWX and Time Service A few issues ago, someone mentioned that at one time, Western Union had a huge international network of telegraph lines. This is true. Until a few years ago -- maybe ten -- it was very common to see TWX and Telex machines in almost every business place. There were only minor differences between Telex and TWX. The biggest difference was that the former was always run by Western Union, while the latter was run by the Bell System for a number of years. TWX literally meant "yperiter echange", and it was Bell's answer to competition from Western Union. There were 'three row' and 'four row' machines, meaning the number of keys on the keyboard and how they were laid out. The 'three row' machines were simply part of the regular phone network; that is, they could dial out and talk to another TWX also connected on regular phone lines. Eventually these were phased out in favor of 'newer and more improved' machines with additional keys, as well as a paper tape reader attachment which allowed sending the same message repeatedly to many different machines. These 'four row' machines were not on the regular phone network, but were assigned their own area codes (410-510-610-710- 810-910) where they still remain today. The only way a four row machine could call a three row machine or vice-versa was through a gateway of sorts which translated some of the character set unique to each machine. Western Union's network was called Telex and in addition to being able to contact (by dial up) other similar machines, Telex could connect with TWX (and vice-versa) as well as all the Western Union public offices around the country. Until the late 1950's or early 1960's, every small town in America had a Western Union office. Big cities like Chicago had perhaps a dozen of them, and they used messengers to hand deliver telegrams around town. Telegrams could be placed in person at any public office, or could be called in to the nearst public office. By arrangement with most telcos, the Western Union office in town nearly always had the phone number 4321, later supplemented in automated exchanges with some prefix XXX-4321. Telegrams could be charged to your home phone bill (this is still the case in some communities) and from a coin phone, one did not ask for 4321, but rather, called the operator and asked for Western Union. This was necessary since once the telegram had been given verbally to the wire clerk, s/he in turn had to flash the hook and get your operator back on the line to tell them 'collect five dollars and twenty cents' or whatever the cost was. Telegrams, like phone calls, could be sent collect or billed third party. If you had an account with Western Union, i.e. a Telex machine in your office, you could charge the calls there, but most likely you would simply send the telegram from there in the first place. Sometime in the early 1960's, Western Union filed suit against AT&T asking that they turn over their TWX business to them. They cited an earlier court ruling, circa 1950's, which said AT&T was prohibited from aquiring any more telephone operating companies except under certain conditions. The Supreme Court agreed with Western Union that 'spoken messages' were the domain of Ma Bell, but 'written messages' were the domain of Western Union. So Bell was required to divest itself of the TWX network, and Western Union has operated it since, although a few years ago they began phasing out the phrase 'TWX' in favor of 'Telex II'; their original device being 'Telex I' of course. TWX still uses ten digit dialing with 610 (Canada) or 710/910 (USA) being the leading three digits. Apparently 410-510 have been abandoned; or at least they are used very little, and Bellcore has assigned 510 to the San Fransisco area starting in a year or so. 410 still has some funny things on it, like the Western Union 'Infomaster', which is a computer that functions like a gateway between Telex, TWX, EasyLink and some other stuff. Today, the Western Union network is but a skeleton of its former self. Now most of their messages are handled on dial up terminals connected to the public phone network. It has been estimated the TWX/Telex business is about fifty percent of what it was a decade ago, if that much. Then there was the Time Service, a neat thing which Western Union offered for over seventy years, until it was discontinued in the middle 1960's. The Time Service provided an important function in the days before alternating current was commonly available. For example, Chicago didn't have AC electricity until about 1945. Prior to that we used DC, or direct current. Well, to run an electric clock, you need 60 cycles AC current for obvious reasons, so prior to the conversion from DC power to AC power, electric wall clocks such as you see in every office were unheard of. How were people to tell the time of day accurately? Enter the Western Union clock. The Western Union, or 'telegraph clock' was a spring driven wind up clock, but with a difference. The clocks were 'perpetually self-winding', manufactured by the Self-Winding Clock Company of New York City. They had large batteries inside them, known as 'telephone cells' which had a life of about ten years each. A mechanical contrivance in the clock would rotate as the clock spring unwound, and once each hour would cause two metal clips to contact for about ten seconds, which would pass juice to the little motor in the clock which in turn re-wound the mainspring. The principle was the same as the battery operated clocks we see today. The battery does not actually run the clock -- direct current can't do that -- but it does power the tiny motor which re-winds the spring which actually drives the clock. The Western Union clocks came in various sizes and shapes, ranging from the smallest dials which were nine inches in diameter to the largest which were about eighteen inches in diameter. Some had sweep second hands; others did not. Some had a little red light bulb on the front which would flash. The typical model was about sixteen inches, and was found in offices, schools, transportation depots, radio station offices, and of course in the telegraph office itself. The one thing all the clocks had in common was their brown metal case and cream-colored face, with the insignia 'Western Union' and their corporate logo in those days which was a bolt of electricity, sort of like a letter 'Z' laying on its side. And in somewhat smaller print below, the words 'Naval Observatory Time'. The local clocks in an office or school or wherever were calibrated by a 'master clock' (actually a sub-master) on the premises. Once an hour on the hour, the (sub) master clock would drop a metal contact for just a half second, and send about nine volts DC up the line to all the local clocks. They in turn had a 'tolerance' of about two minutes on both sides of the hour so that the current coming to them would yank the minute hand exactly upright onto the twelve from either direction if the clock was fast or slow. The sub-master clocks in each building were in turn serviced by the master clock in town; usually this was the one in the telegraph office. Every hour on the half hour, the master clock in the telegraph office would throw current to the sub-masters, yanking them into synch as required. And as for the telegraph offices themselves, they were serviced twice a day by -- you guessed it -- the Naval Observatory Master clock in Our Nation's Capitol, by the same routine. Someone there would press half a dozen buttons at the same time, using all available fingers; current would flow to every telegraph office and synch all the master clocks in every community. Western Union charged fifty cents per *month* for the service, and tossed the clock in for free! Oh yes, there was an installation charge of about two dollars when you first had service (i.e. a clock) installed. The clocks were installed and maintained by the 'clockman', a technician from Western Union who spent his day going around hanging new clocks, taking them out of service, changing batteries every few years for each clock, etc. What a panic it was for them when 'war time' (what we now call Daylight Savings Time) came around each year! Wally, the guy who serviced all the clocks in downtown Chicago had to start on *Thursday* before the Sunday official changeover just to finish them all by *Tuesday* following. He would literally rush in an office, use his screwdriver to open the case, twirl the hour hand around one hour forward in the spring, (or eleven hours *forward* in the fall since the hands could not be moved backward beyond the twelve going counterclockwise), slam the case back on, screw it in, and move down the hall to the next clock and repeat the process. He could finish several dozen clocks per day, and usually the office assigned him a helper twice a year for these events. He said they never bothered to line the minute hand up just right, because it would have taken too long, and '.....anyway, as long as we got it within a minute or so, it would synch itself the next time the master clock sent a signal...' Working fast, it took a minute to a minute and a half to open the case, twirl the minute hand, put the case back on, 'stop and b.s. with the receptionist for a couple seconds' and move along. The master clock sent its signal over regular telco phone lines. Usually it would terminate in the main office of whatever place it was, and the (sub) master there would take over at that point. Wally said it was very important to do a professional job of hanging the clock to begin with. It had to be level, and the pendulum had to be just right, otherwise the clock would gain or lose more time than could be accomodated in the hourly synching process. He said it was a very rare clock that actually was out by even a minute once an hour, let alone the two minutes of tolerance built into the gear works. "....Sometimes I would come to work on Monday morning, and find out in the office that the clock line had gone open Friday evening. So nobody all weekend got a signal. Usually I would go down a manhole and find it open someplace where one of the Bell guys messed it up, or took it off and never put it back on. To find out where it was open, someone in the office would 'ring out' the line; I'd go around downtown following the loop as we had it laid out, and keep listening on my headset for it. When I found the break or the open, I would tie it down again and the office would release the line; but then I had to go to all the clocks *before* that point and restart them, since the constant current from the office during the search had usually caused them to stop." But he said, time and again, the clocks were usually so well mounted and hung that '....it was rare we would find one so far out of synch that we had to adjust it manually. Usually the first signal to make it through once I repaired the circuit would yank everyone in town to make up for whatever they lost or gained over the weekend....' In 1965, Western Union decided to discontinue the Time Service. In a nostalgic letter to subscribers, they announced their decision to suspend operations at the end of the current month, but said 'for old time's sake' anyone who had a clock was welcome to keep it and continue using it; there just would not be any setting signals from the master clocks any longer. Within a *day or two* of the official announcement, every Western Union clock in the Chicago area headquarters building was gone. The executives snatched them off the wall, and took them home for the day when they would have historical value. All the clocks in the telegraph offices disappeared about the same time, to be replaced with standard office-style electric wall clocks. Fortunatly, I was able to grab a couple for myself, and I use them in my home. The one I really wanted quickly became unavailable however: the lobby of the Telegraph Federal Savings and Loan Association (aka Western Union Employees Credit Union) had a beautiful grandfather clock with a Western Union mechanism inside it. I don't know who got that one! Wally took a few clocks home and kept them in his basement, selling them to whoever wanted one. I got one of mine from the Chicago Board of Education employees cafeteria when they remodeled the place and took it down; I got the other one from the men's grill in the old Morrison Hotel when they tore that building down. The one clock dates to 1897, the other to 1945, and they both keep perfect time, even without the Naval Observatory to prompt them periodically. Western Union was a grand old company in its time. During October, I will post excerpts from an article which first appeared in the in 1901, at the retirement dinner of the fellow who was on duty in their Chicago office the Sunday night of the Great Fire, thirty years earlier. His story is fascinating also. Patrick Townson ------------------------------ From: David Lewis Subject: Re: Where Are We Going From Here?

Thanks GTE :) That was indeed rather nice of GTE to permit 800 calls, but none other. Perhaps their business office was an 800-number, and they wanted you to be able to still call them to make payment arrangements? :-) The above selective denial of service can, of course, only be provided with an ESS office. All other telephone companies that I know of simply deny all outgoing service, with not even a dial tone. In a SxS or XY office we would deny outgoing but still permit incoming service by either of two methods: (1) removing the connection on the distributing frame which connected the "deadbeat" line to its linefinder group, leaving the connector group jumper in place; (2) placing two plastic insulating sleeves over contacts on the cutoff relay in the linefinder group, thereby lifting the connection to the line relay. When the customer still did not pay their bill after 10 days, we REALLY got nasty. :-) We yanked his protector, thereby opening the subscriber pair, and we wired his line to an intercept recorder stating that "The number you have dialed is temporarily out of service." We actually left all of the other MDF jumpers in place for several weeks so that if the customer repented and paid his bill plus a service restoral charge, all we had to do was replace the protector and remove the intercept trunk jumper. Working in a central office, at times like this, was not unlike that of playing God. :-) In a crossbar office, service denial methods similar to the above would be employed. In an ESS office, denial of outgoing service is performed as a command function through the maintenance tty. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: tad@ssc.UUCP (Tad Cook) Subject: Modified Plantronics LiteSet Works Great! Date: 18 Sep 89 00:47:55 GMT Organization: very little I got one of the LiteSets last week from DAK. My boss got one a couple of months ago. Being a ham, I could not resist modifying it. I noticed that when my boss got more than 100 ft from the base, he started to fade. Probably wasn't helped by all the RFI radiating computers we have around the office. I saw the the little antenna on the base was about 1/10 wavelength long, so I decided to make a 1/4 wave groundplane out of hookup wire. I popped open the unit and found the ground connection on the circuit board was common with the ground on the negative power input. I ran out a piece of wire for the ground connection. I also saw that because of the short antenna, they had loaded it with an inductor. I disconnected the antenna, and ran my own wire to the outside of the unit, tapping off the coil just a few turns from the transmitter. I put the base unit on a couple of large metal file cabinets next to my desk, and ran my new 1/4 wave (5 foot) antenna wire up the wall. I used wire that matched the wall, so it doesnt look too ugly. Then I ran 2 ground radials, one in each direction, taped horizontally on the wall, and hooked these to the ground wire I brought out of the unit. Then I ran 2 more 5 foot radials, diagonally from the common ground point across the filing cabinets, under potted plants, and down opposite corners of the cabinets to take care of the excess wire. The range on this thing is now phenomenol. My boss and I ran a tesst where I went outside and just kept walking...wonderful clear transmission. At one point after lunch I took a little hike into the woods north of our office, found a nice grassy area where I could lay down and watch the clouds roll by, and took a few calls from customers! I also got in the car and drove, and found that we still had good transmission several blocks away! This was after I got out of the METAL car, of course.

With an automated attendent, it's even easier for twits to call you than it was with a Centrex system. The result of this is most if not all extensions in an office are programmed as "away from my desk" so the call is routed to the voice-mail system. Now if you are in a company that is set up this way and you are trying to reach someone else who is also "away from his desk", you might as well send a letter since neither one of you will ever talk directly to the other. I design voice-mail and automated attendent hardware, but I use a standard answering machine to screen my calls so that I can pick up any call that sounds important. Maybe I should add an option like this to the voice-mail systems we design? Any ideas?

I'm about to move and dreaded my call to Nynex to disconnect my service and then transfer the number (I'm moving within the same town and area code - in fact this number has now survived four moves) to my new residence. I did have to wait awhile but not that long (5 minutes) and then put the request through. I had been hearing horror stories about 1 month backlogs (what with the strike and that fact that 200,000+ students have just moved to Boston) and was very happy to discover that they would do the change within 5 days. The representative then went over my basic charges which was Metro service, touch tone, and call waiting. I said that we didn't want call waiting and we were all set. I then talked to my wife so that we could remove one more item from our endless list of moving to do's and she said that we never had call waiting and had, for example, gotten a busy signal trying to call me the previous week. I called Nynex business office back (waited for 5 minutes again) and asked if we were indeed being charged for call waiting. We had in fact been being charged for call waiting (Nynex doesn't itemize the monthly charges to you can't tell by looking at the bill). I explained that it didn't work and never wanted it in the first place. I was put on hold for about 30 seconds and then was told that my next bill would be credited for 18 months of call waiting - a credit of $48. Needless to say I was very happy. If ever given an option for local carrier I would never change, just as I've never changed my long distance from AT&T. Now I don't know what's going on with negotiations with the strikers and as an aside I agree with their position (from what I've read of it in the local papers) but I'd be worried if I were them. I've never had to wait for more than 20 or 30 seconds to get directory assistance in the past 6 weeks and when I've called the business office I been treated very well. Comparing the service from Nynex against tech/customer support from the biggest (and smallest) computer software and hardware companies that I've dealt with over the past few years doesn't even make sense. Nynex wins hands down - even with half of their staff not at work. Phil Stanhope Manager of Software Engineering Gold Hill Computers, Inc.

Reprinted without permission though the magazine does not have a copyright notice so it seems that they don't mind. My comments in thingies () BT WITHHOLDS VERDICT IN CENTREX TRIAL British Telecom (BT) is conducting an in-house trial of a centrex service but is still undecided on a date for its launch. Rival Mercury (the only other long-distance carrier in the UK) introduced its 2110 Centrex service in May 1987 and, soon after, BT announced its own, Centel, but did not implement it after teething troubles with the switch. Centrex services use software to run the operation of a pabx from the public network. A BT spokesman said: "We have had an in-house trial of a centrex service to gain operational experience, but we are still finalising a business plan. "We want to make sure that when we do start the service, we will be able to deal with all our customers' requirements. "We realised the concept of centrex involved far more than just an alternative to a pabx. It offers, in effect, private network services run on the public exchange," he added. As BT decide on when to launch a service, Mercury is increasing its customer base. According to a spokesman, it has more than 20 customers at over 35 sites. "Centrex has proved to be a very competitive product and is already a major contributor to to Mercury's profits," he said. +--------------------------------------------+--------------------------------+ | K.Hopkins%cs.nott.ac.uk@nsfnet-relay.ac.uk | Kevin Hopkins, | | or ..!mcvax!ukc!nott-cs!K.Hopkins | Department of Computer Science,| | or in the UK: K.Hopkins@uk.ac.nott.cs | University of Nottingham, | | CHAT-LINE: +44 602 484848 x 3815 | Nottingham, ENGLAND, NG7 2RD | +--------------------------------------------+--------------------------------+ ------------------------------ Subject: British Rail's Telephone Network Reply-To: K.Hopkins%computer-science.nottingham.ac.uk@nsfnet-relay.ac.uk Date: Mon, 18 Sep 89 09:31:19 +0100 From: Kevin Hopkins Another article from Computing dated 07.09.89. It seems British Railways are expanding their trackside telphone network, but unlike Sprint (Southern Pacific Railways?) they are not going to offer direct competition to British Telecom and Mercury for long distance calls but are going to lease out capacity on the line to various companies. Read on ... My comments in () BR TELECOMS PLAN HITS DOUBLE SNAG British Rail's (BR) plans to provide a national fibre-optic network for telecommunications will have to wait until the liberalisation of the British Telecom and Mercury duopoly. BR recently created the post of director of commercial telecommunications and appointed Peter Borer, formerly with Kingston Communications which is based in Hull. (In fact it isn't a telecommunications duopoly in the UK when it comes to providing public telephone networks. For historical reasons the council of Kingston-upon-Hull on the east coast, usually known as Hull, has provided its own telephone services within the city, and seems likely to do so for the forseeable future. This department of the council is now known as Kingston Communications. Not to be confused with Kingston-upon-Thames SW of London.) With some 2,000 km of fibre cable, BR has a network of similar size to Mercury. The company already leases capacity to Mercury and has future plans to exploit its communications infrastructure further. Current regulations to encourage competition and and protect British Telecom's position prevent BR from renting or selling its network directly, Borer said. "We are building our communications infrastructure to be ready for the duopoly review," he said. "We see our position as providing a national fibre optic grid as a minority partner, but BR is unlikely to become a public telephone operator." The Government's telecommunications policy stated a review of the British Telecom and Mercury duoploy would not take place before November 1990. "It is unlikely any new government policy will be made until the middle of 1991," Borer said. BR is expanding its fibre network by about 500 km a year at the moment and Borer predicts that its size will almost double in the next few years. +--------------------------------------------+--------------------------------+ | K.Hopkins%cs.nott.ac.uk@nsfnet-relay.ac.uk | Kevin Hopkins, | | or ..!mcvax!ukc!nott-cs!K.Hopkins | Department of Computer Science,| | or in the UK: K.Hopkins@uk.ac.nott.cs | University of Nottingham, | | CHAT-LINE: +44 602 484848 x 3815 | Nottingham, ENGLAND, NG7 2RD | +--------------------------------------------+--------------------------------+ ------------------------------ Subject: More on the History of Telephone Dials Date: 17 Sep 89 12:43:17 EDT (Sun) From: Larry Lippman In article gmw1@cunixd.cc.columbia. edu (Gabe M Wiener) writes: > FYI, I don't know if this has been discussed already, but Strowger's > original system did NOT use a telephone dial.

The first dial telephones in the Strowger system appeared in 1896, and were installed in Augusta, GA. However, these telephones still used four wires plus a ground return, and the dial was substantially different from what we know today. The two-wire (without a ground reference) telephone with dial as we know it today was not invented until 1907. Most of the development work on the rotary dial which eventually led to the 2-wire system was performed by Keith (also of plunger switch fame) in collaboration with the Erickson brothers, all of whom were awarded various patents in this area between 1895 and 1908. > By the way, here's an interesting fact about the somewhat later Strowger > telephone dials.

There were indeed some strange (and incorrect) perceptions about what the public could and could not cope with. Strange as it may seem, between 1895 and 1915 there was some SERIOUS opposition to automatic telephone switching - especially on the part of the Bell System! An interesting quote from the 1913 AT&T Annual Report underscores this feeling: "We have designed, and manufactured, and installed all kinds of switchboards - automatic, semiautomatic, and manual - and we have exhaustively studied the practical workings of every type of switchboard in use. ... As yet it has not been demonstrated that the automatic system would give as good and dependable services as we now render to the public [using operators with manual switchboards] ..." An interesting quote from the historical Hershey book (which I mentioned in a recent article) makes reference to dials and the public: "In the early days of Strowger Automatic it was realized that a four digit number was about the most that a subscriber could carry in his head, so the telephone offices were designated by a single letter. The manual opposition [i.e., people in favor of retaining operators] immediately cried to high heaven that the public did not have intelligence enough to dial one letter followed by four digits." "The literacy of the dear public must have greatly improved in the last twenty years. Now they are expected to dial the first three letters of an exchange name, disregard the remaining letters, and then dial the required four digits. Verily it maketh a difference whose ox is being gored." Another interesting piece of trivia is that dial tone did not come into general use until the late 1920's. Before the use of dial tone, subscribers picked up the telephone and simply waited a few seconds before dialing. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Mon, 18 Sep 89 21:47:06 EDT From: Gabe M Wiener Subject: Speaking of Western Union While we're on the subject of Western Union, here are a few questions about WU that I've had for quite a while. 1. When did WU take the manual telegraph out of operation and replace it with the teletypewriter? I've always been fond of the telegraph myself. I have an 1884 Western Union private line telegraph transmitter/receiver set among my collection of antique telephones. 2. It was mentioned that WU used telco lines. I was always led to believe that WU had their own lines. When did this practice end? Or did it? 3. Do telegrams and mailgrams have any modern commercial application with the advent of electronic mail, the overnight letter, fax, etc.? I have nothing against telegrams, and it would be a pity for such a thing to ever die out, but are they still used in major ways today? (other than the traditional sending of a telegram to a wedding when you're away) 4. Am I right to assume that the "public telegraph office" has more or less been replaced with the 800 Western Union phone number? When did this come to be? 5. What exactly is WU up to these days? I'm sure they're getting into long distance telephone like everyone else. Can anyone fill me in? Speaking of Western Union, you all might enjoy the quotation that I have in my signature.

WUI:650-117-9118 - Western Union internal memo, 1877 [Moderator's Note: Regards your point (2) above, they had (still have) both, depending. Sometimes they even had wire pairs within a telco cable that were 'their' pairs and not telco's for use. It was a hodge podge of things. Western Union always had a very special status with the Bell System, and that included the rates given to WU for their phone service. Their lines always shared the same conduits inside buildings with Bell, even prior to the court ruling which said Bell had no right to make other folks vacate the conduit when they (Bell) caught them in there. Oddly enough, it was because they were allowing WU to use their conduits at will that the court said they could jolly well allow all sorts of commuications services in there. Likewise with house pairs; WU always took what they wanted. Regards your point (4), the public offices were pretty much phased out during the 1970's in favor of the 800 number. Then they began realizing there was money to be made in the business of money transfer, so they began cutting deals with banks and currency exchanges to function as Western Union agencies for the purpose of taking in/disbursing funds transferred around the country. But the currency exchange/agencies of today do NOT resemble the fabulous old public offices of a quarter century ago. In smaller towns, they sometimes worked through a telegraph agency rather than have their own office. That is, someone else owned the business and got a commission for handling traffic for WU. In small towns, the agent could never make a living from WU alone, so he did other things also. In Coffeyville, Kansas, and Hammond, Indiana, to name just two towns, circa 1940-45, the telegraph agency was in the bus depot; the agent sold Greyhound tickets (as well as the tickets for every other bus line which came through town) and operated the telegraph machines as well. The guy in Hammond had enough going on to keep a girl busy working the counter two shifts a day and a guy who was there all night. The telegraph machines (usually two or three of them) would chatter constantly in the background, and the phone was ringing constantly, 24 hours a day. Regards point (5), they now have a long distance service; they have public e-mail (EasyLink); they still 'do' telegrams; money transfer and sundry.

Jack had an FX Line which terminated in Washington DC, and Cathy had an FX line which terminated in Baltimore. Perhaps someone else out there in netland could give a better description of an FX line, but here goes my explanation... An FX line is a suscriber line which terminates in a central office other than the central office which provides local access to the telephone network. These numbers are most often used by businesses that have operations in another city which would justify the added expense of one of these lines. If you subscribe to this feature, you would literally have a phone number which would be non-local. Therefore, referring to Clancy's novel, in calling his own house from his yard over an FX line, he would have to make a toll call. Also, most people are familiar with this service as radio stations often use this service -- especially stations that have large broadcast areas. I remember growing up and when the radio station would have a contest, they would list six or seven numbers that listeners could call into to win. While each of these numbers was from a different geographical area, they all terminated at the radio station. Kevin L.

This was accurate as of a few years ago. Since then AT&T has introduced two COCOT's, the AT&T Private Pay Phone and the AT&T Private Pay Phone Plus. These are designed to operate on any standard residential-type line, coin control is not required. One other thing to add to Larry Lippman's description of AT&T (WECO) Coin Telephones. Recently, AT&T introduced a follow-on to the venerable 1D2-type coin telephone. This is the AT&T Next Generation Coin Telephone. It is a standard coin telephone for the Local Exchange Carriers, plus it has many new capabilities made possible by a microprocessor and a modem. The phone reports to a central computer various bits of diagnostic data (eg. handset missing, chute jammed) traffic data, and coin box information. It can also be programmed from the computer for things such as initial rate.

Part of the As a matter of fact, it was installed in about 1974. At that time they offered no features whatsoever. It was many years before I learned that they were offering call waiting and call forwarding (and nothing else). At a place served by this switch, I had particular use for three-way calling, but it has never been available. Down south, I know that GTE does offer 3-way in the No. 1 EAX. The scuttlebutt around the times the switch went completely down was that some local character who knew nothing really about the equipment was fooling around with the programming and managed to screw it up to the point where it would no longer process calls. The reason it was down for so long is that they had to fly a specialist up from Santa Monica to straighten the mess out. The EAX call forwarding has a neat feature (seriously). If you dial 79#, you will be immediately forwarded to the number previously forworded to. This is handy if you regularly forward to the same number, or want someone to forward your phone without having to reveal the number it's being forwarded to. As an aside, I should point out that GTE Mobilnet (the wireline cellular provider in the Bay Area) is quite an excellent operation. The coverage is good, the service reliable, the people responsive. Calls complete in about 2 seconds (as opposed to about 20 seconds for PacTel Cellular in the LA area). GTE Mobilnet offers superior subscription plans to Cellular One (the Bay Area non-wireline system owned primarily by Pacific Telesis) and has been first with all of the GeeWhiz features like a big area, follow-me roaming, etc. We have all theorized that it must be some other GTE, since GTE California is just the opposite--running the worst phone company I have ever seen. > The Bell System has also used subscriber line carrier of the lowest > quality - the infamous Superior/Continental AML.

But GTE in California used theirs as a matter of routine. A favorite trick of the pea-brains in Los Gatos was to install subscriber carrier and then at some future time turn off the service of the metallic subscriber (battery and all). After some indeterminate amount of time, the nicad in the SC unit would become weak and the carrier subscriber's service would just fade away. This actually happened to me. You should have heard me trying to explain this to some 611 droid. You should have seen how long it took them to fix it. After several days I rigged up an outboard supply and got my service back. That fix would be there to this day if they hadn't finally added more cable to the area and converted my line to metallic. And this was business service! John Higdon | P. O.

I for one, however, am still waiting for the strike to end; I've been without service for over 4 weeks, and while I can't pin them down on an installation date, the most optimistic target I've been given is November. The problem is that I just moved into a new apartment that has never had phone service before. To establish service, NYNEX must send someone to phsyically connect the wires. They apparently need the strikers for that. Disconnecting and reestablishing service to older units is apparently not a problem, because that can be done through software from the central office.

And there was one evening when I couldn't even reach the operator, much less anyone else, even though I had dial-tone. And how do they deal with problems? They "check out the line" and "find nothing wrong". Perhaps the equipment is so antiquated that they don't have many people left who know how to diagnose and fix its problems.) Incidentally, does anyone know why I might not be able to use the 10xxx access codes? Could it be related to the fact that we only have pulse-dialing (or some other aspect of our antiquated system)?

I've noticed you said many of the services had already been available and that Starline only enhanced them. As I said before here in Australia we are only starting to have the original services. One thing I do notice is that as the number of services that are available to the customer increases and as more of them becomes active then this business of having to press *nn (nn two digit number) or #nn becomes a real mess. Why can't your telco give you a more sophisicated handset ? I suppose there's no point unless you have ISDN signalling. Even with DFTM, there'll needed to be a lot of logic built into a handset just to display useful info to the user. I just wonder if the interface between the user and the CO is more intelligent, how much of this service interactions stuff can be gloss over ? You see I am really interested in the interactions between enhanced features. I didn't get a chance to read your ISDN summary but do you remember if there was any mention of the use of ISDN signalling to enhance the way enhanced services are delivered to the customer. The topic in itself is worth discussing. May be you can post this message on comp.dcom.telecom and see if there anyone out there who would be interested.

What are the 'K' and 'W' for? In Australia, each state has a number: 2 New South Wales 3 Victoria 4 Queensland 5 South Australia 6 Western Australia 7 Tasmania Postcodes in the state are of the form Nxxx, where N is the state number and xxx are three digits. Radio station call signs are of the form N-cc for AM and N-ccc-FM for FM eg in Sydney (NSW) there are 2BL, 2WS, 2ABC-FM, 2JJJ-FM, 2-DAY-FM etc and in Melbourne (Vic) there are 3LO, 3AK, 3MMM-FM (triple M) 3-FOX-FM (the Fox) etc. The call signs of country stations usually reflect their location, eg 3GL in Geelong, 2PK in Parkes. This means that if you hear the call sign of a radio station, you instantly know which state it is from, and can hazard a guess at the area too. Is there a system in the USA? Daniel u5434122@ucsvc.unimelb.edu.au [Moderator's Note: We covered this pretty extensively several issues ago. Check old messages with the 'Radio Station Names' title. In a nutshell: The first letters are assigned all over the world by international agreement. The United States gets W and K mostly; Canada gets C; Mexico gets X, etc. In the United States, broadcast stations in the eastern part of the country use W. In the western part of the country, they use K. The W or K is followed by two or three other letters, assigned by the Federal Communications Commission. The dividing line between W and K is the Mississippi River, a large body of water which runs the length of our country from north to south. There are some exceptions to the W/K rule, but not many. The two or three letters following the W/K are often specifically requested by the station. If they are not already assigned the FCC will usually give them out. Frequently they will be the initials for the name of the owner, or have some other significance to the owner of the license. Quick examples in Chicago: WGN = World's Greatest Newspaper (owned by Chicago Tribune) WLS = World's Largest Store (from long ago when it was owned by Sears Roebuck) WMBI = Moody Bible Institute WCFL = Chicago Federation of Labor WBBM = We Broadcast (from the) Broadmoor Ballroom WVOA = The Voice of America (in Red Lion, PA -- not Chicago) Every country gets one or more letters assigned for the first letter. In Equador, the starting letter is H; thus a very loud shortwave station heard all over the world from Quito, Equador is HCJB. And who will be the first TELECOM reader who knows what those letters mean? :) PT] ------------------------------ From: munnari!ucsvc.unimelb.edu.au!U5434122@uunet.uu.net Date: Wed, 20 Sep 89 13:51 +1000 Subject: Re: Who Pays For International DA?

Situation: lady friend and I went away for the weekend to a rented house at the beach. Arrived early evening, after Real Estate Co. had closed. Needed to call her children to tell them phone number to call in case of emergency. Phone number NOT written on phone at rental house. Problem: called "0", asked for number of phone we were calling from. Was told that she knew but couldn't tell us. Surly attitude from both operator and her supervisor (Gulf Bell). Called customer assistance at both Sprint and MCI. Sprint person didn't know, but gave us a 5-digit number to call that would help us. Number didn't work. MCI person knew nothing. Called 911, they WANTED to help, they had the number in front of them on their screen, but were afraid that it would cost them their jobs (they had good attitude, offered alternative way to route kids to us through them). Summary: NO WAY to find out phone number. Questions (2): 1. What's the deal? Of the several people who KNEW but COULDN'T tell us what the number was, NOBODY knew why they couldn't tell us! They just mumbled something vague about violating privacy laws. Is it REALLY the case that the legal system ASSUMES that the reason you want to know the phone number you're dialing from is that you are a BURGLAR who wants to know the number of a house you've just broken into so that you can then charge calls to that number? If so, why aren't Phone Books illegal? 2. HOW can one readily discover the number of a phone one is dialing from. Surely, there is some number to dial that will parrot back to you the dialed-from number? Is there a std num for this function? Thanks, Russell Shackelford School of Information and Computer Science Georgia Institute of Technology, Atlanta, GA, 30332 russ@prism.gatech.edu (404) 834-4759 [Moderator's Note: And this, too, we have covered at length in recent weeks. There is no formula -- no set number -- which works in all places for the purpose of ring-back and/or number i.d. But there is the Townson Plan, which always works without fail: Use the phone in question to place an AT&T person- to-person call to someone who won't be there to receive the call. For example, in the case at hand, call yourself at your home number person-to-person. When the kiddies answer the phone, the operator will ask for you; you'll not be home, but since you are calling person-to-person the operator will 'leave word' on request, asking the kiddies to take a message for daddy to call as soon as he comes in. Tell the operator, "....just leave this number here, operator, I will be around all evening...". And the accomodating operator, without thinking twice about it, will tell the kiddies, have your daddy call Operator 8 in Podunk, and ask for 123-4567." Thank you, operator! Thank you indeed. By leaving word on a person to person call, the operator has to give the number and you'll overhear it being given. Have your pencil poised so *you* don't have to ask her to repeat it! Don't worry if the kiddies got it right or not. In theory, the operator is supposed to split the connection before passing that information; it is rare that they bother. And if they do, just place another call; the next operator will be more cooperative, I'm sure! PT] ------------------------------ Date: Wed, 20 Sep 89 0:44:08 CDT From: TELECOM Moderator Subject: The 'Public Telegraph Office' Someone the other day asked, 'Have the public telegraph offices mostly been replaced by the 800 phone service?' The answer is yes. The 800 service along with personal terminals and accounts on Easy Link for hundreds of companies which used to rely on telex and/or TWX have virtually decimated the telegram, and the telegraph public office. I mentioned that in small (and some medium size) towns, Western Union did not actually own the facilities, but operated through an agent; someone who had other things going on as well, such as the local agent for the bus lines; now and then the local (independent and rural) telco office, etc. In larger cities such as Chicago, St. Louis, New York, Boston, Los Angeles and similar, Western Union operated their own public message centers. The Chicago office is well etched in my mind, in the 1955-60 time period. The office was 1930-ish Art Deco design. It was about the size of a typical high school basketball gymnasium, with the same sort of vaulted ceilings. In front, several small writing desks, like in a bank, where one would stand and write out the message on a form submitted to the clerk. The fountain pens were chained to the counter so they could not be stolen. A large calendar on the wall, and of course, the 'telegraph clock'. At the counter, which was marble, three or four places for clerks, although there were usually just one or two on duty at a time. Behind them, nine or ten rather large, somewhat noisy teletype machines. Usually there were two operators attending all the machines; they would walk to one, peer at the paper feeding out, look at the next machine, etc. Sitting down at a machine, these operators -- invariably men, although the counter clerks were frequently women -- would type messages and receive them. The room had a constant din from the machines. One or more was constantly typing. A small bell, driven by a just like today would go 'bing bing bing' and the motor inside the machine would start going with a soft sort of whirring noise. Maybe two seconds later the keys would start printing and the carriage would move back and forth on the platen. As quickly as it started, it would stop. The motor would shut off, and the machine would go silent. But the starting and stopping could not be predicted. Sometimes all would be running, other times just two or three. Just as one would stop, another would start. And the men would walk around, gather up paper from each and give it to the clerks at the counter. One machine would stop, and immediatly bing! bing! another one would start. The operators seemed to be fast typists. Picking up a piece of paper from the clerk, one would sit at a machine and begin typing -- quite fast it seemed to me at the time, although I learned later they were only going about 60 baud, or some ridiculous pace by today's standards. And always with a cigarette hanging out of their lips as they sat there banging away. The clerk functioned much like a school teacher grading an essay paper. You'd take your message to the counter written out, and with a red pencil the clerk would say, "what's this word here?", "how do you spell that name?", "I can't read your writing, you will have to go back and print it over again". When satisfied, she'd count the words and looking at a chart say, "well, that's fifteen words, gimme dollar seventy five". You would pay, and she would hand the message over to the operators for typing into the network. From time to time the operators would hand over messages to the clerk, who would speak loudly, "Smith? John Smith?", and if Smith was waiting around for his message, he would come to the counter to get it. Sometimes it would be registered, meaning he signed for it, and the operator would send back a message to the other end saying delivery had been made. If Smith could not be located in the office, then a messenger -- either a twelve year old kid or a seventy five year old man -- they seemed to have no one in the middle age at all doing this work -- would take the message and set off on a bicycle to deliver the message to Smith at his office or home. Twenty four hours a day, seven days a week this went on. If money was wired to you, they would write a check payable to you, which you were free to endorse and cash right there if the clerk had enough money in the drawer, or you could cash it elsewhere. If you just hung around the place all day, talking to the people coming and going, you got quite an education and heard the life stories of everyone passing through, it seemed.

Rushing in to the local New England Telephone building a few months ago to pay my (typically late) bill, I stumbled across an interesting telephone museum. It's in the New England Telephone building on Franklin Street in Boston -- the city where, of course, the telephone was invented. The museum is a replica of Alexander Graham Bell's garrett workshop where the famous conversation ("Mr. Watson, come here" etc.) occurred. Although the room itself is a replica -- the actual building was demolished decades ago and the street it was on no longer even exists -- most of the paraphernalia are real, including the workbench, some really odd looking gizmos, and some notebooks. Also some of Bell's early commercial equipment, which at the time was used mainly for burglar alarms. It's not worth making a special trip to Boston, but if you're here anyway, it's worth half an hour. You can't miss it -- it's just inside the main entrance of the Franklin Street building (the art deco building festooned with microwave horns).

Call Completion to Busy Subscriber may be totally implemented in the originators switch. It would only poll the other switch to see if the Called party is busy. The destination switch would have no knowledge of the timers for CCBS or possibly even that CCBS was invoked. So, if a user at the destination switch wanted to invoke a service, such as CFU, it would allow it. If CCBS is implemented by the destination switch, via a message from the originating switch to implement, then this info could be used to disallow CFU. One ot the things being strived for in CCIT is a consistent service view to the customer, you cannot have the service be different depending on the implementation, so CFU takes precedence.

We had two microwave sites in Germany, two in The Netherlands, and two in Belgium, in addition to a maintenance site at Roclenge sur Geer, Belgium. We constantly used the telephone system to contact all six sites from Belgium and I learned inter- national dialing early in life. It was less than 15 minutes driving between the Maastricht site (located in a Dutch PTT tower) to the maintenance site in Belgium, but was an international call. What made it particularly bad was that our site was located on the dividing line between the Flemish (Dutch) and Walloon (French) speaking sections of Belgium. Telephone maintenance was all but impossible and winter conditions at our sites in the Ardenne Mountains made it worse. We had all of the sites linked by HF radio as a backup, but often we would drive to Maastricht across the border to use the microwave communications channels connecting the sites to make reliable contact! Our customers were all military as part of the Allied Forces Central Europe (AFCENT) network and we essentially duplicated the existing HF/VHF radio links and PTT/RTT networks. As I was leaving Europe in 1969, satellite networks were taking over much of the communications requirements. Belgium had to be one of the more interesting countries in Europe at that time, since they were just instituting vehicle drivers licenses in 1969 (as I recall) and most drivers were grandfathered into the system. The others had to either take a written exam _or_ a road test! Belgium also had one of the highest accident rates in Europe then.

I believe there is a >central number you can call to retrive your messages (at least there is >on the voice mail offered with my cellular phone). Late 1970's through early 1980's Plantronics Inc. in Santa Cruz, CA built and marketed a system called CentraVox--a CO based answering machine for individual subscribers. FCC ruling against recording devices in COs finally killed the product line. Last operating system that I am aware of was part of the PNB system in the Seattle area. The service was popular among the masses, I am told. Consisted of a 19" rack mounted aluminum box with p/s and central tape driving motors. 12 individual line modules would independently push tape and a rubber roller against a rotating shaft to drive the tape. Two tapes, an announce on a loop and about 20 minutes of message tape were included in an interchangable unit about the size of many cassette recorders. All of the electronics other than the voice recording was digital. The system was controlled by DTMF signals from the subscriber site and there was a tone sequence indicating waiting messages when the handset was taken off hook. VOX was the other feature, up to a 20-min length of message was possible, and the system sensed the end of "intelligibility" and then rewound the tape to that point to await the next call. All features for control were available from the unmodified home telephone and there was a remote included so that you could access your service by calling your home number remotely and sending a BCD signal to authorize. You could change announce, listen to and erase messages all from any telephone. Cost was very low to the consumer as well... Too bad it died just pre-1984! ------------------------------ From: Edward Greenberg Subject: Re: Speaking of Western Union Date: 20 Sep 89 23:20:45 GMT Reply-To: Edward Greenberg Organization: NetCom- The Bay Area's Public Access Unix System {408 997-9175} In article gmw1@cunixd.cc.columbia. edu (Gabe M Wiener) writes: > 3.

When I got married in 1982, one of my friends sent a telegram from out of state. What I got was a telephone call from a bored operator. She read me the message, and offered a confirmation copy, which was printed out as a mailgram and mailed about three days later. I've given up on Telegrams. I'd rather send a fedex package with a Texas Sized Jelly Donut or something. The poster says that he'd hate to see them die out, but I think that they have. There's probably good reason to dictate a message, and have it printed out and delivered by a messenger, but that's hardly cost effective these days. For instance, for $25, you can send an MCI Mail letter which is delivered by Purolator courier within four business hours. If telegrams cost $25, who'd use them though. -edg Ed Greenberg uunet!apple!netcom!edg ------------------------------ From: Mike Morris Subject: Re: Phone Remarks in Clancy Novel Date: 20 Sep 89 23:00:20 GMT Reply-To: Mike Morris Amanda Walker writes: %In article , %loughry@tramp.colorado.edu (J.

This is a good chance, though it's a nickel-dime matter compared to John's complaints. Yesterday I was ordering new service and the lady asked me if I wanted touch-tone service. I said no, and she acted real surprised and said, "Don't you have any pushbutton phones?" I said "they're pulse" and that satisfied her. I think that's distinctly fraudulant. If they are going to be allowed to push so hard for their extra dollar a month, at least they should be limited to correct terminology and ask, "aren't you using Touch-Tone (TM) phones?" I had had non-touch-tone service in my home for years-- I was able to use touch-tones to dial with no problem, and was rather proud that I was avoiding the $1 + per month ripoff. About a year or two ago, the business office called my wife on some pretext to "review" our phone service, asked her the same question, and pressured her into ordering the extra service. They probably are raking in several million dollars a year on that scam. Why are they be allowed to charge extra for this anyway? I'm sure it doesn't cost them anything, given today's technology-- pulse dialing may even cost them more, since the line must be open longer. John, I've heard that the PUC has a bbs.

It is related in so far as a general rule of thumb: If your CO equipment doesn't do DTMF, then it is too antiquated for equal access. All CO switches can be adapted to accept DTMF, but those that have to be adapted don't intrinsically do 10XXX dialing. To my knowledge, there are no SXS offices operating FGD (feature group D). No. 5 crossbar can be adapted for it with an adjunct called CONTAC (we have a lot of that here). However, if CONTAC is installed, then the switch will do DTMF, since that's how the adjunct communicates with the crossbar's originating registers. CONTAC itself would rather see DTMF from the subscriber. It is very intolerant of off-speed rotary dials. Pulses must fall between 8-12 pps or the call will fail (no 20 pps dialing). All electronic switches (ESS, DMS, EAX, etc.,) can run software that supports FGD and all electronic switches intrinsically accept DTMF. John Higdon | P. O.

LA has most of it's FM station on a 5,000' mountain so both the AM and the FM has excellent coverage - LA county has 2 complete area codes (818 and 213) and pieces of 2 more (714, 805). Many of the radio station also cover portions of San Bernadino and Riverside counties (area code 619). A while back (pre the 213-818 split) I noticed that more and more stations were giving out 213-520 numbers for dial-in. After the split, I noticed that they were giving out the same number as "dial 213-520-xxxx or 818-520-xxxx". Well, to make a long story short there is only one 520 exchange, but it can be accessed from both 818 and 213. A acquaintance in Pac Bell tells me that if they can get GTE to co-operate that they might be able to do the same thing with 714, only it would have to be something other than 520, as that is already in use in the city of Anaheim. It probably won't happen with 619 as that is north San Diego, and all of Riverside and San Bernadino, and many of the lower powered stations don't reach that far. My '84 Riverside book does not list a assignment for 619-520 however. I was told it was done at the (collective) stations request to lower the number of FX lines and hence the cost, but I kinda doubt that - Mike Morris UUCP: Morris@Jade.JPL.NASA.gov ICBM: 34.12 N, 118.02 W #Include quote.cute.standard PSTN: 818-447-7052 #Include disclaimer.standard cat flames.all > /dev/null ------------------------------ From: Rich Wales Subject: Re: Radio Station Names (Australia, Canada, HCJB) Date: 20 Sep 89 20:58:39 GMT Reply-To: Rich Wales Organization: UCLA CS Department, Los Angeles In article munnari!ucsvc.unimelb.edu.au!U5434122@uunet.uu.net describes radio station names in Australia: Radio station call signs are of the form N-cc for AM and N-ccc-FM for FM eg in Sydney (NSW) there are 2BL, 2WS, 2ABC-FM, 2JJJ-FM, 2-DAY-FM etc and in Melbourne (Vic) there are 3LO, 3AK, 3MMM-FM (triple M) 3-FOX-FM (the Fox) etc. The call signs of country stations usually reflect their location, eg 3GL in Geelong, 2PK in Parkes. This means that if you hear the call sign of a radio station, you instantly know which state it is from, and can hazard a guess at the area too. There is apparently no international requirement that radio stations all have call letters conforming to the international (ITU) plan. If there were such a requirement, Australian stations would have call letters starting with AX, VH-VN, or VZ. For that matter, the Australian call signs mentioned above overlap all over areas of the naming space reserved by the ITU for other countries. For example, 2PK (indeed, *all* calls starting with a 2) "should" be in Great Britain; 3AK ought to be in Monaco; and 3MMM belongs in China. Of course, Australia is not alone in ignoring the ITU list. In Canada, the radio and TV stations of the CBC all have call letters starting with the letters CB -- which, under international treaty, must mean that the CBC is really based in Chile. :-} (Canada doesn't own *all* of the "C..." call letter space, you see -- only CF-CK and CY-CZ, in addition to VA-VG, VO, VX-VY, and XJ-XO.) Is there a system in the USA? As Patrick (our moderator) mentioned, there is no comparable system for commercial radio or TV call signs in the US (other than the K/W split). However, amateur radio calls in the US *do* indicate the general part of the country; the digit indicates one of ten areas (which do *not*, how- ever, correspond to the first digit of our "ZIP" postal codes). This system isn't perfect, though, since if a ham moves, he gets to keep his call sign even if his new residence is in a differently numbered part of the country. Patrick added: In Ecuador, the starting letter is H; thus a very loud shortwave station heard all over the world from Quito, Ecuador is HCJB. And who will be the first TELECOM reader who knows what those letters mean? :) HCJB is run by an evangelical Christian group; the letters stand for "Heralding Christ Jesus' Blessings".

When they inquired further, they were told that this was true, not just for their area and their normal long-distance carrier, but that no place in the United States and no long-distance company had such a number, and that they were not yet allowed to be allocated. They said something about a committee of seven people and about some independent agency that decides what numbers get allocated to what LD companies, and when, all for the sake of fairness. Sorry to be so vague, this information is second-hand. Can anyone tell me if this is true, and if so, what is this independent agency, where did they get their authority, what is their charter, and what, if any, method is there to their allocation of numbers? Is it possible to reserve an 800 number in advance? Also, how long does it usually take, from the time you apply for an 800 number, to get it put into service? That is, assuming no problems like trying to reserve unavailable numbers. Thanks in advance. Guy Shaw Paralogics paralogics!shaw@uunet.uu.net or uunet!paralogics!shaw [Moderator's Note: The 'independent agency' is called Bellcore. Some Bellcore people are readers of this Digest. Bellcore came from the old Bell System, and specifically from AT&T. In years past, AT&T had the duty to assign all area codes and prefixes. Since divestiture, Bellcore does this. They assign prefixes to telephone companies and long distance carriers upon application for same. I don't know whether 800-646 is assigned or not; I'll take your word for it. It will not be assigned until Bellcore chooses to do so, and then, all telcos everywhere will be notified to program their machinery to respond to 800-646 in the same way. When it gets assigned to some (most likely) long distance company, they will turn it on at their leisure, and having done so, you may then apply *to that company* for an account. Until then, you'll have to settle for some other number. There is nothing your local telco or any long distance carrier can do about it.

It looks like the article was in turn based on a press release. The Swedish phone company says it will improve service to residential subscribers. Faults are to be fixed within one day. Repair visits are to be scheduled to the nearest hour; if the craftsperson doesn't show up during the scheduled hour, the subscriber's line charge for 3 months is rebated (SEK 142, or about US$21). Broken coin phones are to be fixed within one day. At large airports and train stations, coin phones are to be fixed within 3 hours, and calls are to be free when the coin boxes are full. I'll believe all this when/if I see it. Another new service is detailed call billing for subscribers connected to AXE offices. This will only be available for international calls, and will of course cost extra. At present, phone bills simply give the total number of units per quarter, and the line charge. An exception is bills for mobile phones; these show each number dialed. Many subscribers object to this for privacy reasons, so the billing for mobile calls is to be changed to a single figure for all calls. Surprisingly, it is legal in Sweden to listen to mobile calls, including cellular calls. Scanners for the appropriate frequencies are available.

There was even a home football game, where some students hauled a large bed-sheet sign around the infield track which read "GTE SUCKS", the police didn't get it confiscated until it made it most of the way around (this may have been intentional??). It drew a standing ovation from BOTH sides I heard (I did not attend this game). GTE-Mobilnet, seems to bear no relation to the GTE-landine folks, they are a complete separate division, reporting to a common parent. The Mobilnet employees really give a damn about the quality of their service. I know several of the engineers/techs at the Indy MTSO (switch) which serves most of the center 1/3 of IN. I often give them signal reports (we are 60Mi north of Indy), reports of channels flaking out and other misc problems. If I find a flakey channel, they will down it immediately. They have been several times when the Indy people have gotten other cellular carriers to fix non-GTE follow me roaming problems (Bell South Mobility in Miami). Once I was talking to a GTE- Mobilnet engineer at the local cellsite (via a landline to a wall phone in the cell site), there was this horrible buzz (60 Hz hum as if one side of the landline is grounded), and they replied, "Yea, this phone has been this way since it was installed (3 months ago), we cannot get GTE to make our phones work!" Other bits and pieces of conversations with GTE Mobilnet have shown that they have much the same (or worse) problems with "GTE" that you and I run into. Other tidbits about Mobilnet: They offer a huge "local" calling area (air time only).. which is most of 317 area + some 219 & 812 areas.. You call "219-NXX-YYYY" (no 1+ or 0+) (I am in 317 NPA) to make a "local" call to their areas in 219. They use Motorola switch and RF equipment (the best). works well with portables in buildings 8Mi away. They carefully balance transmit power with receiver patterns.. so as you approach the service area, you start to "hear" the cell (in service lite) real close (mile or two) of where the cell site can year you. Ameritech and others, blindly turn up the cell xmit power, "blanketing" the area, and have a zone of 20-25 miles, were your mobile will "see" good service, but you still cannot send or receive calls, since the cellsite cannot hear you. I have heard it said, that competing carriers have power wars so the cell phones which are not programmed for one carrier only will "lock on" to the strongest paging channel. GTE Mobilnet does not do this. Mobilnet also uses "Bognar (sp?)" antennas, which even on the same tower, and 20' lower than the competition, still provide much better building penetration and less multipath problems then the competition. Their voice-mail is even "free" (air time only) as is the follow-me roaming (free meaning no flat monthly fee here) Geo.

I'm not sure about ISD, though. I may as well take this opportunity for some reminiscences... the phone system is, of course, a government monopoly under the Department of Posts and Telegraphs. They handle all phone lines, trunks, telex, microwave links, etc. Ah, the telephone service! Those memories... some areas in New Delhi (where I grew up) have a waiting list of 10 years for a 'phone connection. No DTMF dialing here, almost all the exchanges are mechanical. (About 5 years ago a digital switch was introduced on a trial basis - worked quite well, from what I remember.) In the summer after almost every rainstorm thousands (I'm not exaggerating!) would be knocked out. One of my childhood memories is being taken to a crossbar exchange by my father (he used to be in the telecom field and had a few cronies in the Post and Telegraphs Department) and watching/listening to those things. I was about 8 at the time and can't really remember the details, though. :-( My grandfather's phone was even more interesting - it was on a rural exchange and had an operator that would complete calls by plugging jacks on a board (don't know the jargon for this). The exchange itself was about 6 miles away and every summer the line would be destroyed by the monsoon. (This was about 5 years ago) STD was introduced about 10 years ago, I think, and was more expensive than the regular operator-assisted "trunk call." (To make one of those you had to call a number and book the call at some priority, with the cost increasing geometrically with higher priorities... it would often be 4-6 hours for the call to go through at the affordable priorities) The trunk call may still be cheaper than an STD call. The city codes for STD calls are of variable length - for instance New Delhi is 11 but smaller towns have upto 4 digits. Caveat: All of the above information is at least 3 years old.

I received a sad note today in my mail at Chinet from James J. Steiner, asking for information on a rush basis from the folks who read the Digest, and I said I would pass his request along. He has a new employee working in his office who came from Puerto Rico just three weeks ago, apparently here on the mainland for the first time in his life. And now after such a short time in a new and strange place, this poor fellow is faced with the news that his homeland has been ransacked and virtually decimated. The phone service to PR is still erratic at best. Apparently a special 800 number has been established by the long distance carriers as a special humanitarian effort to folks who need to establish contact with friends and family there. ** Does anyone have the number? Can you locate it? ** Also, there are a couple numbers in New York where relief efforts are underway for Puerto Rico. What are those numbers?

For next: As I write this, the word is the hurricane is definitly expected to hit the Carolinas in the early morning hours Friday. The television on Thursday night said that it is almost inevitable at this point that there will be extensive, very horrible damage along the east coast. I hope those of you in the affected area will be able to maintain your communication links, and that you will keep TELECOM readers posted on emergency restoration efforts going on. My understanding is that many residents are voluntarily evacuating the area; and that the telcos, among other vital services, are gearing up to repair what they assume will be quite extensive damage, if the storm hits as predicted, and it is now a ninety five percent certainty that it will. Patrick Townson ------------------------------ Date: 21 Sep 89 8:56 -0700 From: laura halliday Subject: STD/ISD in Commonwealth Countries Here in Canada, our phone system is (almost) a clone of the American system. We even have the same country code. We don't say STD and ISD - we used to say DDD (Direct Distance Dialling), but now the phone book (Vancouver, B.C., anyway) just talks about 1+, 0+ and International calls. With the exception of Bell Canada in Ontario, Quebec and parts of the Arctic, each province has its own phone company. Some are private (e.g. B.C. Tel), while some are government-run, like Alberta Government Telephones. The phone companies cooperate to provide long distance service within Canada through Telecom Canada, while overseas access is through Teleglobe Canada. There are a few independent phone companies, in cities like Prince Rupert, B.C. and Edmonton, Alberta. We don't have any choice on long distance carriers, though some companies are trying to change that. The Canadian Radio, Television and Telecommunications Commission (CRTC), our analog of the FCC, flatly refuses such requests. Phone costs here in B.C. are moderate compared to American ones. Connecting a line costs $23.50 (all costs are in Canadian dollars; the exchange rate is currently about $C1.00 = $US0.85), while the monthly charge for a line in Greater Vancouver is about $14.00. Long distance within Canada is pricey; Vancouver to Toronto during the day is $0.68 a minute, while Vancouver to New York is $0.63 a minute. I never did figure that one out...Call setup time is good, and line quality is usually good. Service is fairly quick - you may have to wait a week for your phone to be connected if it's a busy time of the month. We have the option of buying our own phones, or renting them from the phone company. Custom calling is available in areas with electronic switching, and costs (and works) about the same as in the U.S. B.C. Tel have just introduced a long distance deal, with the poetic name `Between Friends', where you pay a fixed monthly rate for half an hour of long distance, then get a discount on further long distance. It's good deal if you make a lot of long distance calls sufficiently far away, since the additional minutes cost you $0.18 within B.C., and $0.33 for the rest of Canada and the U.S. ...laura ------------------------------ From: Sharon Lynne Fisher Subject: Wrong Numbers With Nobody Talking Date: 21 Sep 89 14:50:58 GMT I moved a couple of months back, and I've had a weird problem since then.

Edward Vielmetti, U of Michigan Math dept. [Moderator's Note: 'Enterprise' a/k/a/ 'Zenith' numbers were an early version of automatic reverse charge calling, serving the same function as 800 numbers do today. When you dialed your operator and asked for Enterprise xxxx, the operator consulted first her own records, and if necessary, the Rate and Route people. Like many 800 numbers on non-dedicated lines, Enterprise numbers translated to some regular number where the subscriber had authorized automatic acceptance of collect calls. Like 800 numbers, not all Enterprise numbers were valid in all places. Some were local only, some were long distance only, or some other combination. All Enterprise calls had to be placed manually by dialing the operator and asking for the number. Some Enterprise numbers were non-pub, just like some 800 numbers, and were only used internally by the subscriber's employees. If it appeared in the phone book, a list of acceptable calling points was included. Enterprise service is no longer offered, but is grandfathered to subscribers who want to keep it for some reason instead of 800 service.

When anyone in the foreign country wants to phone the Dutch business, he/she phones this special number and the Dutch business will be billed (sometimes the caller pays the LOCAL call tariff, but generally its free).

I would urge a bit of caution in identifying teletypewriters as "three row" or "four row" devices; the preferred method should be 5-level (Baudot) or 8-level (ASCII). While the implication may be that 3-row are 5-level Baudot devices, and that 4-row are 8-level ASCII devices, this is not strictly true. French and German 5-level Baudot teletypewriters are 4-row devices, with some of these 4-row German machines made by Siemens being common in the U.S. TWX service was started by AT&T in 1931 using 5-level (i.e., Baudot) teletype machines. TWX was totally manual service with the connection established by an AT&T TWX "operator" until 1962 when dial switching was installed. Also, until this time only 60 wpm 5-level teletype apparatus could be utilized on the TWX network. Simultaneously with the introduction of dial connection service, the TWX network was changed to 100 wpm (110 baud) 8-level (ASCII) to take advantage of newer teletypewriter apparatus, such as the Teletype Corp. Type 33 and Type 35. For a short period of time both 5-level and 8-level apparatus co-existed on the TWX network using 5-level <--> 8-level translators, but the 5-level apparatus was phased out by 1964. TWX switching was originally handled by regular WECO #5 crossbar offices which had some separate line and trunk groups for TWX service. The behavior of a dial-up TWX line is virtually identical to that of a regular telephone line. It was a voice-grade line which used a 103-type data set. Most Telex service operating on leased lines utilize a totally DC circuit (i.e., there was no modem) from the subscriber location to the central office. The DC circuit discipline is usually either neutral or polar, depending upon service area and circuit length. Once in the central office, however, the DC circuit is often converted to 43-type telegraph carrier. Modems have been used with leased lines on Telex service, but they are generally the exception rather than the rule. The "original" Western Union Telex system was installed in the U.S. in 1957; it actually obtained world-wide access through the Canadian Telex system which was installed in 1956. All of the message switching apparatus used in the original Western Union Telex system was manufactured by a German vendor, Siemens-Halske, who has produced much of the Telex station and message switching apparatus used elsewhere in the world. Western Union later established its own direct Telex links to other countries on a world-wide basis, and no longer routed messages through the Canadian access point of Montreal. At some point in time - but I am not certain when or of the exact details - Western Union split its operation into two separate companies: "Western Union" (WU) for all domestic U.S. Telex, TWX and other services, and "Western Union International" (WUI) for all communications and services NOT domestic to the U.S. I don't believe that the WU-WUI split was exactly voluntary on their part; I believe there were some regulatory, legal and financial legal issues involved. WUI has been owned by MCI for several years. The relationship between WU and WUI is somewhat unusual. If you have WU Telex or TWX service and send an *international* Telex, you must use an international carrier such as WUI, RCA, ITT, etc. You access the international carrier through your WU terminal, and you may choose the international carrier on a call by call basis. So the point is, WU does business with WUI in the sense that WUI may serve certain WU customers. However, WUI also drectly offers Telex service with terminals in the U.S., and to some extent they compete with WU for basic service. Perhaps some telecom reader knows more about the WU and WUI split and their relationship. > Today, the Western Union network is but a skeleton of its former self. > Now most of their messages are handled on dial up terminals connected > to the public phone network. It has been estimated the TWX/Telex business > is about fifty percent of what it was a decade ago, if that much. Well, that's no surprise. Cost and improved, alternate transmission methods such as FAX have substantially supplanted Telex and TWX service. As an example of cost, in 1976 my organization first subscribed to TWX service; we bought our own ASR-33 and paid for the monthly TWX service from WU. The basic monthly charge at that time (less usage, of course) was around $ 30.00 per month, which *included* an additional mileage charge because we were located outside the Buffalo, NY metropolitan area. By 1985 our basic monthly charge was up to $ 135.00 and our traffic was way down because of the use of FAX. Since I wasn't too happy with WU anyways, I told them to pound salt and we switched to RCA Global Communications for straight international Telex service using a dedicated dial-up line (i.e., we installed a telephone line with a dedicated 300 baud terminal which RCA calls when they have incoming traffic). Our Telex traffic is now 99% international; we may have received one domestic message so far this year. Even international traffic is going FAX, and our Telex traffic diminishes every year. If this keeps up, we may well ax the Telex service within the next five years. However, our cable address is easy to remember (RECOGNIZE NEWYORK, if you're curious :-) ), and we get some international traffic on the Telex translated from our cable address instead of from our actual Telex number. > Then there was the Time Service, a neat thing which Western Union > offered for over seventy years, until it was discontinued in the > middle 1960's.

The Pacific time zone of the U.S. was not serviced by the Naval Observatory, but by a distributing clock located at the Mare Island Navy Yard. Until the WU time service was discontinued, the "distributing" clock at the Naval Observatory and at the Mare Island facility generated synchronizing pulses for regional WU clocks. The distributing clocks sent pulses at two times per day: 1155 to 1200 hrs, and 2155 to 2200 hrs. Pulses would be sent for five minutes right up to the hour itself. No pulse would be sent on the 29th second of each minute, and for the first four minutes no pulses would be sent on the 55th through 59th second. On the 59th minute, and only on the 59th minute, no pulses would be sent on the 50th through 59th second, with a single pulse at first second of the hour. How's THAT for useless trivia? :-) Each day at approximately 1130 hours the distributing clocks would be corrected based upon the Naval Observatory master clocks, which were in turn corrected by astronomical observations. The overall accuracy of the WU clock system was a few tenths of a second. It was no better because of the various relay operate times, and to a lesser extent because of electrical propagation delays since electrical signals in long communication cables travel much slower than the speed of light. Of course, all of the above time standard methods are now quite obsolete and have long been replaced by the use of rubidium and cesium "atomic" clocks. > Western Union was a grand old company in its time. That's certainly true.

I suppose we are technically-oriented enough here that 'three-row' and 'four-row' could have been replaced with other terms. But those were the terms WU used to explain the machines to their customers. The WU Directory had a detailed picture of each type keyboard (three or four row) and the subscriber was supposed to select the one resembling his model, then read the instructions associated. There was a section which explained how the one type was to connect with the other type as well. Regards clock service, did you know at one point, circa 1930-50, the FCC required all radio stations to have a Western Union clock on the premises for accurate time-keeping? And did you know that for about forty years, the famous beep-tone heard on WGN (720 kc, Chicago) came from the clock itself? The station ran a wire from the little red light bulb in the clock to a little device which made the beep; and that was wired right into the transmitter. For nostalgia purposes, they still give the beep every hour, but it hasn't been from the clock for over twenty years!

In the above mentioned article, you mentioned that the speed was around 60 baud. Well, it was actually something called "75-speed" which indicated a maximum speed of 75 WPM, transmitted in 5-level "baudot" encoding. After doing all the mumbo-jumbo af adding start/stop bits, etc. this translates to an equivalent bits-per-second of 56.83 or thereabouts. A system I worked on once had to monitor transmissions from a telco switch which also used this. An interesting sidelight is that they could transmit the full upper-case character set, the numerics and a goodly supply of punctuation using just 5 bits. (Actually, they used a "switch" character to flip-flop between meanings of particular bit patterns. The "alternate" set would continue to be used until the "switch" character was seen again.)

I had tried to call them early last evening, with limited success. Using AT&T resulted in an intercept recording that mentioned the hurricane. Using Sprint, I got either a reorder tone, a ring which was answered with a recording that "All circuits are busy...", or a completed call. My family had their answering machine on, however, so I didn't actually make contact until they called upon arrival in Asheville. I'm sure the problem was just a deluge of other calls to relatives, which tied up the circuits. Around 1 AM this morning, after the eye of the hurricane had passed through, I dialed the Charleston number, and got a ring, but no answering machine. Presumably the power was out. As far as I could tell, the phones were operating. During the night, Cable News Network spoke to people over normal phone lines, as well as cellular. Around 2 AM, they spoke (by phone) to a woman who was working at the Southern Bell office in downtown Charleston. She mentioned that, with the exception of two barrier islands, all phone service was still in operation. She mentioned that this was due to 79% of their lines being underground. Overall, I think it was a very impressive showing by Southern Bell.

Very nice stuff. My question is where might I buy an 11-hole Stowger dial phone, or a Western Union clock? (Would be sooo much fun to synchronize it to WWV. Both the historian and techno-nerd in me start drooling at the thought.) How about simply the oldest dial phone which will still talk to a modern switch, or an even older non-dial phone which will ring and let me answer? Must I just go look through the regular antique channels, or are there better ways? I might have just acquired an expensive taste...

Pacific Bell recently announced (in my phone bill which came today) that Alameda and Contra Costa Counties (Oakland, CA, and vicinity) will be split from the rest of Area Code 415 (San Francisco &vic.) on October 7, 1991, into Area Code 510. Does anyone know why we get 510, when there are still N0X/N1N codes available (not many, but still 909 and 917 off the top of my head)? Also, any particular reason for starting with an old Western Union code? Now that we've unleashed the great flood of possible area codes, will there be a rush to split more NPA's? I looked through an atlas a while back and saw several areas that were pushing the population figures at which splits seem to take place. For anyone interested, here follows the text of Pac*Bell's note: 415 area code SPLIT Beginning October 7, 1991, Alameda and Contra Costa Counties will have a new Area Code, 510. San Francisco, San Mateo, Marin and parts of Santa Clara County, as well as the islands in San Francisco Bay will retain the 415 Area Code. An easy way to remember this change is to think of San Francisco Bay as the Area Code boundary. The new Area Code is necessary to provide phone numbers for new customers in this expanding area. If your business is located in Alameda and Contra Costa Counties, remember only the Area Code will change. Your 7-digit local telephone number will remain the same as will your local toll-free calling areas. Our change of Area Code may affect the operation of some of your programmed telephone equipment. In particular, automatic dialing devices, speed calling services, alarms and mobile phones may need to be reprogrammed. Your equipment vendor will be able to advise you, whether your telephone equipment needs to be reprogrammed. As you order printed materials, such as new letterhead, advertising, and business cards, please keep the October 7, 1991, change in mind. We will send you another reminder as the 1991 date draws near. -- Linc Madison = rmadison@euler.berkeley.edu [Moderator's Note: 909 and 917 are available, and I suppose 706, 903 and 905 will be also once they are no longer needed to hack our way to Mexico from non-IDDD exchanges. But its a funny thing about 909: Telenet has used that for their own administrative 'area code' for many years on their network and I've a hunch Bellcore will take sympathy and make it the last one to be put in service elsewhere. My guess is 917 will go, along with a couple more of the XX0 codes first. By then, maybe 706, 903 and 905 will be open, etc. I think 210 and 310 are also valid choices from Bellcore, no?

Several years ago, my college installed a new ATT phone system (System 85, I believe) We're talking digital links, fiber optics, microwave link to a 'satellite' building, etc. I'm wondering if this (or other) digital systems have been prone to any 'boo-boos'. I remember last year, we had several days of chaotic telephone service (on campus). Things like dialing 9 and getting a high pitch blast in your ear, and dialing on-campus numbers only to end up listening to another conversation (but they couldn't here you :). This stopped for a while, then came back, and finally it seems they got the problem fixed. (this happened with both the digital and analog sets used on campus). So, just wondering if anyone else had had prior experience like this, and if it was more or less liking to happen wth the 'old fashioned' systems then with todays digital switching, electronic wonders.

A few days ago, the Cubs management announced that ticket sales would be handled by Ticketron, and that phone orders would be taken commencing at 6 PM Friday night. Only several thousand tickets are available to the public, versus a million or so people in northern Illinois who would like to attend at least one game. At 6:00 PM tonight, *thousands* of calls began pouring into the Ticketron phone lines, where tickets were sold on a first-call, first-served basis to credit card holders. By 6:01 PM, Illinois Bell was so saturated with traffic the network almost stopped functioning completely. Waits of three to five minutes for dial tone were not uncommon, and call completions were almost as rare. It has to be the most frustrating thing I can think of to wait five minutes for a dial tone only to accidentally dial a wrong digit and have to hang up and (after waiting for new dial tone!) start over. The next most frustrating thing would be to finally get a dial tone, place the call and be told by the other end, 'due to heavy call volume, we are unable to complete your call at this time....please try again later.' Those of us who know a few things about the matter simply hung up the phone and went to do other things for a few minutes....but now, almost two hours later, the problem is continuing for two reasons: 1) People are still banging away trying to get through to Ticketron, although I am sure every ticket to the Cubs World Series must be gone by now. 2) The people with less knowledge of the system are still sitting by their phone, taking it off hook, waiting a minute or two and hanging up, then going off hook again and unwittingly putting themselves at the end of the queue. If they eventually decide to hang up and go watch television instead, maybe the network can normalize and become stable once again. I've had it to the eyebrows with the Cubs. I have to ride the subway at least two or three nights a week from downtown to my home, and it seems like this past summer invariably its been at the same time as one of their night games was letting out. Since they have successfully managed to screw up the CTA service on the northbound Howard line after their night games, I guess it should be no surprise that Illinois Bell will be screwed up with ticket sales calls for the next few days. In this issue of the Digest, some other commentaries about the use of special exchanges for mass calling are included.

I'm sure all of us have heard horror stories about network blockage when 50,000 little people tried to call Santa when the local Bozo show announced the number. This was happening all to often and the local network is not designed to handle this type of traffic. I'm sure the phone company convinced the radio station to use a number assigned to the MASS ANNOUNCEMENT EXCHANGE. This network is designed to limit traffic at the point of origin, and except for a few quirks, it works great. The network I remember only provided 2 trunks from any central office to one of the 4 tandem switches. Each tandem had 4 trunks to the host switch. Most radio stations had from 2 to 10 lines hunting a lead number. No matter how big a load is offered only a small % of callers would actually use network resources. The system was fair because every caller from every central office had an equal chance of getting into the contest line. The problems with this network were minimal. If more than one radio station at a time ran a contest, chances were that the 2nd station would not get any calls for several minutes. Sometimes the DJ was not told by engineering how the system works and we would get trouble reports. An example: Radio station DJ gets ready to give away free tickets to a sold out concert. Goes to the call director to "check out" the lines. Places 4 calls to the contest line and only 2 ring in. Complains that the %^@@$ network is no good. Wont take no for an answer. Test board dials 2 calls each from 2 different exchanges. DJ is another satisfied customer until next time. ------------------------------ From: Joe Talbot Subject: Re: Prefix '520' For Los Angeles Radio Stations Date: 22 Sep 89 08:33:25 GMT Organization: ATI, High desert research center, Victorville, Ca In article , morris@jade.jpl.nasa. gov (Mike Morris) writes: > klb@lzaz.att.com (K.BLATTER) writes: > > LA has most of it's FM station on a 5,000' mountain so both the AM and > the FM has excellent coverage - LA county has 2 complete area codes > (818 and 213) and pieces of 2 more (714, 805).

This works the same as 976, both area codes translate to the same thing. The 213/818 520 prefix is a "choke" prefix, designed to prevent Radio and TV station contest calling from disrupting the network. Typically only 2-4 trunks are available from each office. A special prefix does not appear to be needed, often, in smaller communities, a prefix and a single hundreds group function the same way. Examples: Colton (714) 431-5XXX, Phoenix used to be that way, maybe still is (602) 260. Other choke prefixes of note are: Chicago (312) 591-XXXX, San Jose (408) 575-XXXX, Orange County (714) 977-XXXX, San Francisco (415) 478-XXXX, San Diego (619) 570-XXXX. > Well, to make a long story short there is only one 520 exchange, but it > can be accessed from both 818 and 213. A acquaintance in Pac Bell tells me > that if they can get GTE to co-operate that they might be able to do the > same thing with 714, only it would have to be something other than 520, > as that is already in use in the city of Anaheim. It's really too bad that 520 in Anaheim didn't get used. The 520 prefix was already in service in LA years before 520 even got assigned. 520 in Anaheim has a whole bunch of big centrex/DID customers on it, no hope of any change. (One customer had a recording reminding callers to dial 213 before the number because of huge numbers of misdirected calls!).

Well, one would think that someone in a Western Union office would have a listing of Western Union city codes, huh? I guess this must be a symptom of WU's "poor health". In any event, if one really cares, they can find a complete listing of all WU city codes in any WU Telex Directory. There are over TEN THOUSAND WU city codes for the U.S. and Canada, which range from "AAAI" (Auburn, IN) tp "ZUMB" (Zumbrota, MN).

[Deep Springs College] (Bruce Hamilton) ---------------------------------------------------------------------- Date: Fri, 22 Sep 89 14:50:53 EDT From: Gabe M Wiener Subject: Payphone Innards Organization: Columbia University It's really surprising how talkative a telco man can become. I've found an easy way to strike up a conversation with a NYTEL repairman. Just ask, "Is the strike over?" (knowing full well, of course, that is isn't). Earlier today, I was passing a NYTEL guy finishing up work on a payphone and I did just that. He immediately started explaining that he was an upper-level computer-systems manager filling in on the field work, in particular, in replacing payphones. "Replacing them?" so I asked. "We're replacing the electromechanical payphones with all electronic ones." Gently pushing for more info, I got him to open one up and show me the difference. From the outside they look identical to a regular telco slot. But the inside is radically different. The upper section (the removable one) is virtually hollow. Nothing at all in there except for the inital coin recepticle (but NOT the counter) the keypad, and a few other parts. On the inside section, however, are a number of removable modules. The mechanical coin detector/counter has been completely replaced with a digital one. It is a square-ish black module that is removable (he removed it to show it to me) and connects to the chassis with a ribbon cable). It's solid plastic on the outside, and simply has a coin inlet and a coin outlet. The only real electromechanical part left in there is the coin hopper, which looked the same as always. One thing I noticed on the inside of the phone was an LCD readout. I asked him about it, and he explained that it was used in troubleshooting the phones. Whenever these phones have problems (jammed coins, etc.), they automatically call into a central computer and report it. They also call in and report when the coin box is nearing full. When a serviceman comes to repair it, he plugs a special cord circuit into a socket in the phone, and the LCD indicates various status factors of the unit. He explained that they also have time-clocks in them, so that they will upload their statistical usage data during the night). Another cute feature is that if the phone knows it has service trouble, it will open up the coin hopper so that any coin put in will be immediately returned. If someone phones in trouble, the central computer can signal the slot to open the hopper. The actual coin signalling, however, is the same as usual. Regular in-band tones generated by an on-board module (he pointed it out. It's on the upper right side of the phone, right above the data-communications module). All these modules, btw, plug in with ribbon connectors to the chassis which, I assume, contains the motherboard. There are only about 100 of these nifty phones in operation right now, but they're trying to replace more and more of them as time goes on. It's moving rather slowly because of the strike. So, gentle reader, we see that the strike DOES have some benefits...namely running into service folks who will gladly take a payphone apart in front of you to show you how it works. On top of that, he also told me some other interesting info, about my local switch, etc. It seems that most telco folks will be glad to take the time to talk to passers-by if they seem interested (this is especially true for the management personnel who are filling in for the strike).

First of all, the Mass Calling Prefixes (as I were told they were called) were designed as others have described them to limit the number of calls to one exchange or number so that hundreds of thousands of calls wouldn't interfere with the normal operation of the phone network. Nowadays this is only needed for the local exchange network, the long distance carriers have computers to restrict the number of calls to a given number to no more than a couple from each tandem. The 900 number used to call the President way back when was the experiement that led to this. I won't go into the details of this because someone already described the system, but they basically set up regional centers which took limited numbers of calls and sent them to a target spot in Washington and two lines to the president (one for the Call In Progress and one Waiting). *Everybody* else got a recording saying try again. It was toll free unless the call was answered. I had fun. In Hamden (a suburb of New Haven, CT), there was a small radio station, WCDQ (I was friends with the son of the owner of the station). The station was within the walking distance of my home. Their number was on the 203-281 ESS #1 exchange, as was mine. This was before the days of "user settable speed calling". I had WCDQ's phone number programmed in as *1 (it was *1 to *8 then, not 2# to 9# like it is now). When they announced a contest, I was quick on the trigger. All the other phones in the area were on step-by-step machines. I had the *fastest* route to the station. I was caller 2, 4, 6, 8, and the winner, 10. every time. They eventually told me I could only win one contest a month. Sigh. They almost told me I couldn't win anything since I was friends with the Station Owner..... but ..... My first experience with a MCP was in NYC, 212-955 (now also 718-955). I was calling in Long Distance from Hoboken, NJ, so it wasn't so bad. I did manage to win a few times. The system there seemed to be geared towards callers from outside of the 212/718 area codes. Maybe because I was in 201 helped since the lines went through ATT. In LA I found 213-520 (and now 818-520). Interesting about them was that they did two things. They 1) prevented you from flooding the network, and 2) prevented you from using speed dialing. The way they did that was to insert pulse dialing between the last tandem and the target machine. In additon, calls from that machine went out to the tandem FIRST so they would be treated the same as outside calls. I am fairly sure that 520 had a step tandem of sorts, because you always got the familiar rapid busy signal if you overloaded the tandem switch. Bop bop bop bop bop bop............. At the very least it was a step front end to the final machine making it impossible to be quick-on-the-fingers. I got around that by using several lines. --jsol [Moderator's Note: Jon Solomon was the founder of TELECOM Digest and the moderator for several years.

Incidentally, I get these calls both long-distance and local. > Anybody have any idea what's going on? Originating modems do not emit tones on connection. Terminating (or answering) modems answer the call with one of a variety of tones to indicate the type of modem and its desired speed of connection (300, 1200, 2400, or other). The clicking you hear in the earpiece is probably the modem switching its various filters in and out of circuit to determine what type of modem it is connected to. Try whistling a low, continuous tone into the mouthpiece (and varying the frequency you whistle) and see if you get the other end to start its transmission speed negotiation preamble (that will definitely identify the other end as a modem). I have used that trick to see if connections I was trying to debug were getting through to a modem, when I couldn't bridge a speaker or butt set onto the line. I don't design or work with modems other than as a user, so I may be wrong on the explanations of the clicking. I can speak from experience about the originating modems not generating tones, unless some of the newer, fancier modems that have come into use in the last few years do things differently.

No, Sharon, a modem originating a call to another modem remains silent, and expects the answering modem to make a tone first. (Much like people ... the answering party generally speaks first.) Your calls may, in deed, be coming from a modem, or perhaps a fax machine. If it's convenient, you might wish to let your modem answer, and see if the calling person or device responds to its answer tone with a carrier. Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

[Deep Springs College] Date: 21 Sep 89 22:19:07 GMT Reply-To: Bruce Hamilton Organization: Xerox Corp, El Segundo, CA As an alumnus of Deep Springs College (1971-74), let me fill you in on the phone situation there. For at LEAST the past five years, it has been direct-dialable at 619/872-2000. Curiously, they only discovered this by ACCIDENT! They started getting wrong numbers and asked the caller what number they had dialed. (I guess Continental Telephone was afraid that if they admitted that they'd added direct-dial, they'd have to support it, or something stupid.) Within the last two years or so, ConTel's service got so noisy and unreliable that DS spent several thousand bucks and put in a microwave relay to replace the land lines that go up Silver Canyon from Bishop, CA and down Wyman Canyon to Deep Springs, CA (somewhere around 20 miles). Anyhow, they still have just the one phone line, which unfortunately does NOT support fax or modem, and along with the microwave they got some sort of mini-pbx that serves as an intercom system for around the ranch. Back when I was a student, we still had crank phones. Crank one long for the operator (originally in Bishop, but now way down south in Victorville, I believe). There were about half a dozen parties on our line, so you had to listen for our "Deep Springs #2" ring -- one long, three short. The other parties included a CalTrans highway maintenance station a mile away, a phone booth in Oasis, and a couple of other ranches over in Fish Lake Valley. It didn't even help to write down the "mark other place - inward routing" stuff, because it seemed like they changed the numbers every couple of years. I have written down 619+058+181, and I also have 887-225-0002, for what it's worth. p.s. For more information about Deep Springs, which was founded in 1917, has a student body of about 24 men, and combines a two-year full-scholarship liberal arts program with ranch work and self-government, you can write to the college at P.O.

I seem to recall a diagram in earlier WU directories, but we discard the old WU directories, so I have nothing to refer to. According to the WU directory that we do have, WU does not appear to use "three row" or "four row" any more, but refer to the machines as "Model 32" and "Model 33". Of course, WU does not mention Baudot or ASCII, either. There is no illustration of any keyboards, but there is an illustration of how to read 5-level and 8-level paper tape - which is a skill that all state-of-the-art people involved with telecommunications should master, along with being proficient in Morse Code. :-) As an amusing aside to the recent issues about "junk fax", there is a similar problem which exists with telex service - but it is less severe. Most of the solicitations come from the international telex carriers, such as WUI, ITT, RCA, FTCC, etc. However, the WORST part of "junk telex" is not material received on the telex machine, but fraudulent invoices for listings in either non-existent or virtually non-distributed telex directories. This is a somewhat more sophisticated scam similar to that of phony "Yellow Pages" invoices for directory advertising. The largest and most widely used international telex directory is the multi-volume "Jaeger & Waldmann International Telex Directory", more commonly referred to as the "J&W". The J&W lists the subscribers of ALL telex carriers on a WORLDWIDE basis FREE OF CHARGE. The J&W is sold throughout the world, and is not affiliated with any particular telex carrier. The purchase price and legitimate paid advertising in the J&W obviously defrays the cost of listing all telex subscribers. In addition, each telex carrier publishes their own telex directory which is sent free of charge to all of their subscribers, and which obviously does not charge for a subscriber listing. My favorite scam invoice comes from a company located in Hollywood, CA called "The Telex/TWX Directory", and the "invoice" amount is generally for slightly over $ 100.00. "The Telex/TWX Directory" sounds pretty much like the legitimate Western Union directory, right? Wrong - its a scam! Somehow, most of these phony firms manage to stay one step ahead of the law. What is even more interesting is that many of these scams originate in foreign countries and pertain to a listing in some phony "international telex directory". My organization receives phony international telex directory invoices at least ONCE PER MONTH, with most of the letters originating in Germany, France, Belgium, The Netherlands and Hong Kong. The foreign invoices generally have no "fine print" which functions as an attempted legal disclaimer; they are blatantly fraudulent since the perpetrators know that they are essentially immune to any prosecution or civil litigation since the remittance address is outside the U.S. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: Mike Morris Subject: Technical Specifications of TTY Machines Date: 22 Sep 89 16:31:37 GMT Reply-To: Mike Morris (Nickolas Landsberg) writes: > > In the above mentioned article, you mentioned that the speed >was around 60 baud.

A bit of nit-picking here: the upshift character was called FIGS (for FIGureS, and the downshift character was called LTRS. All the machines had a feature called USOS for UnShift On Space, and sometimes a message would have to be resent because an inexperienced operator would send a message with a lot of numbers on a machine that would drop back to letters and be received on a machine that wouldn't. Smart operators sending strings of numbers would send a FIGS after any space character just in case. As a side note, the standard speeds were 60, 75 and 100 words a minute, using either a standard length stop pulse or a 1.5 length stop pulse. There are electronic speed converters around, most machines came geared for 60, or 66 (WU's own speed). The type-15 and type-19 machines could be geared for 60, 66, or 75, but had maintenance problems at 75. The later type-35 machines could be geared for 60, 75, or 100 wpm, or have a 3-speed gearbox. 5-level machines are still in use in the amateur radio field, and still passing traffic - the name there is RTTY for Radio TeleTYpe, sometimes called "Ritty". Here in Los Angles, much of the local activity is on 146.70 Mhz, and some of the stations are quite sophisticated, using selective call (imagine a answering machine), and answer-back, etc. Bless the man that designed the first UART chip with 5,6,7 and 8 bits/char! Teletype has discontinued parts availability for the Type-15 and Type 19 (which I have in my station) and for the Type-28 (which I may upgrade to soon- for hauling it away!) - all 5-level). BTW, my type-15 is manufacture-dated 1933, and is still in full working condition - I had to replace the internal wiring as the cotton insulation had hardened and cracked, and become oil-soaked. I saw a picture of a type 20 - it was a 6-level machine used in typesetting - the brief story said it was a 5-level unit with a case bit. The type-26 was a light-duty printing drum machine (like the later 32/33 line) - the ones I worked on were just not designed for 8-hours-a-day use. I was told that there was a type 29 and 30, but sever saw literature or any machines. The Type 32 is the last of the mechanical 5-level machines, (I was told it was a redesign of the 26) and it interestingly came in a 3-row and a 4-row configuration. The famous type 33 is the common 8-level machine that I learned BASIC on, interestingly it's stiff keyboard is blamed for the "tersenes" of UNIX (tm). The type 35 is the standard 8-level heavy duty machine. The 37 was an attempt at a upper/lower case 8-level machine - I've only seen 3 in my life, and one of those was in a scrap heap - supposedly it was a maintenance nightmare. The 40 was an attempt at a do-all-end-all integrated system that never made it - I saw only a few in use, and those were used as dumb terminals. The saving grace was the printer - it was built like a mini-IBM-1403, a train mechanism and was almost indestructible. I saw several in use on minicomputer systems, running day in and out with no downtime. The type 42 is a 5-level version of the 43 8-level dot-matrix machine - the one with the strange paper size (8.5 inches wide, _including_ the perforations!). If anybody wants a 43, let me know - I've access to 70 in excellent condition in a warehouse - make offer!. I know several local amateurs that use 43s as logging printers, and as _quiet_ RTTY stations (with UART-based 8-level-to-5-level converters). 8-level RTTY is legal in the amateur service, but is (naturally) incompatible. Packet is slowly replacing RTTY for message handling, due to it's natural connectivity (it's X.25 based) but there are still a lot of people using the old mechanical marvels. Amateur radio has many facets: voice, television (yes, you can own a TV transmitter!), radioteletype, packet, radio astronomy, satelites, and more.

Actually, there were about half a dozen different versions of 5-level Baudot teletype systems which had baud rates that varied from a low of 45.5 at a nominal 60 wpm to a high of 75 at a nominal 100 wpm. What confuses the issue is that while 8-level ASCII has the same duration for start, information and stop bits, some of the 5-level Baudot systems used a LONGER stop bit duration which was a non-integer multiple of the start and information bits. For example, the earliest Baudot systems ran at 45.5 baud with a start/information bit duration of around 22 ms, and a stop bit duration of around 31.2 ms; this provided a nominal 60 wpm. The 75 wpm system in Nickolas Landsberg's example is 56.9 baud with a start/information bit duration of around 17.6 ms and a stop bit duration of around 25 ms. Even though there were timing differences, from a practical standpoint many of the 5-level Baudot systems did in fact communicate with each other. The Teletype Corp. Model 28 apparatus could run at either 60 or 75 wpm, and the Model 32 apparatus could run at a maximum of 100 wpm, if it felt in the mood. :-) The Model 32 may have been faster, but it was a LOT less rugged than the slower Model 28! > A system I worked on once had to monitor transmissions > from a telco switch which also used this.

All 5-level Baudot machines have a "Letters" mode and a "Figures" mode in order to fit the various alpha characters, numbers, punctuation symbols and control characters into the coding scheme. These modes were set by corresponding control characters, 11011 for FIGURES and 11111 for LETTERS. The most unusual device I have ever seen which generated 5-level Baudot to drive a Model 28RO page printer was the WECO 520 Emergency Reporting PBX. This system, which was designed during the 1950's, was an early PBX used by police and fire departments to handle call box telephones used by police and the public. A teletype printer was used to log the box number of a reporting telephone and the date/time. The PBX used wire-spring relays and crossbar switches. The interesting part is that WECO used a sequential series of standard 22-position stepping switches to actually encode and generate the properly-timed 5-level Baudot characters to drive the teletype printer! One could look at the bank wiring on the step switches and actually SEE the character encoding for , , the digits, etc. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" [Moderator's Note: A curiosity when I was employed by the University of Chicago Telecommunications Department (then, in 1959-61 they just called it the 'telephone room') were the two TWX machines. One functioned normally and brought us messages from everywhere, but the other was on a special circuit to the local telco central office, known as the 'Kenwood Bell' due to its location on the corner of 61st Street and Kenwood Avenue, just south of the campus. All our long distance service went through there. To place a long distance call then, most people dialed 211 and passed the call to the operator. We plugged in on our board to tie-lines which went straight to certain positions at telco. They knew it was UC calling, and all we had to pass was the caller's extension number; then we could cut out and go on to other calls. Once an hour, the aforementioned TWX would come to life and a message would print out listing 'time and charges by extension'. We took this and matched it with the toll tickets we started when first putting the call through. All this machine was ever used for was to bring us the time and charges, for billing purposes to the campus extensions. IBT billed the campus master account; we re-billed each department.

With an automated attendent, it's even easier for twits to call > you than it was with a Centrex system. While my organization has never had Centrex at its facilities, in July we did install a Northern Telecom Meridian SL-1 with auto-attendant features to replace a somewhat aging electronic PABX. The "twit call" problem actually seems to have diminished as callers find themselves with a voice mailbox in 4 rings as opposed to an unanswered call reverting back to the PABX attendant with the previous system. Getting back to the attendant then creates the opportunity for the "twit" to ask the attendant to - gasp! - page me! :-) With the Sl-1 system, getting back to the attendant requires a second call - which usually deters "twits" - UNLESS they know the "secret", which is to dial "0" with a touch-tone telephone after they have reached any voice mail box. Some of our users have elected to make the announcement of dialing "0" to reach the attendant in their personalized voice mail box greeting (a feature of the SL-1), but I have so far decided not to so so. > The result of this is most if not > all extensions in an office are programmed as "away from my desk" so the call > is routed to the voice-mail system. That is the way ALL of the extensions in our system are programmed; i.e., calls unanswered in 4 to 5 rings go to the user's voice mail box. I was originally somewhat skeptical of the voice mail box system, and was going to have my external calls permanently programmed to revert back to the "live" attendant on no answer. However, this turned out not to be necessary as outside callers have "adapted" to the voice mail system. > Now if you are in a company that is set up this way and you are trying > to reach someone else who is also "away from his desk", you might as > well send a letter since neither one of you will ever talk directly to > the other.

Maybe I should add an option > like this to the voice-mail systems we design? Any ideas? At first, I was not certain how well the voice mail system would work out, and I had some reservations as to how useful it would be. The first few days following cutover did nothing to mitigate my concerns as a number of our telephone users had "fun" with the voice mail system by leaving obscene messages for other extensions, changing the personalized voice mail greetings of unsuspecting users (before passwords were implemented), etc. However, within a week everyone got the "novelty" aspect of voice mail out of their system, and got down to serious business. I also had mixed feelings about voice mail because I have been a proponent of greater use of UNIX electronic mail. However, to paraphrase an old saying, "You can put a UNIX terminal in a person's office, you can lead them to UNIX mail, but you can't MAKE 'em use it." :-) The voice mail system has certainly diminished use of UNIX mail, except between two of our facilities which are located 25 miles apart and have no voice tie lines. The bottom line is that voice mail has been EXTREMELY effective in improving communication within my organization and, three months after cutover, has been accepted and used by everyone in our organization. HOWEVER, I believe that there is a particular reason why voice mail has worked so well for us - all of our telephone sets (except for data lines) are multi-line electronic telephone sets with a "message" indicator and a "message" key which immediately accesses the voice mail box system. No user within the facility ever has to call the voice mail system to ascertain if they have mail waiting - they merely glance at the LCD "message" indicator on their telephone set to see if it is flashing. Many earlier voice mail systems do not have this feature, and I believe the key to success in voice mail systems is to eliminate the repetitive chore of a user having to dial a code to check their mail box. Of course, we have a voice mail access number so that users within the facilities but away from their desks can check their voice mail boxes, and any user can also check from outside the building using a number dialed through the auto-attendant. Sometimes I miss a call by a second or two and it "escapes" to the voice mail box system. At first, I wished there were some way to retrieve the call, but since I can get any message within seconds after it was left I no longer care about this situation. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Sun, 24 Sep 89 14:07 EDT From: NUTSY FAGEN Subject: ATT System 85 terminals Does anyone know how I can get a hold of a catalog for available digital terminals (telephones) to use with an ATT System 85 network.

Anyway, it could be a modem calling you (like a wrong number in someone's Systems file!) and you would hear nothing when you answered.

When the phone company runs out of pairs and there are more lines that need to be installed, subscriber carrier allows two subscribers to use one physical pair of wires. At the CO (or wherever it is necessary to channel two services into one pair) a carrier unit is installed and a matching unit at the "carrier" customer's location. The unit superimposes 30-60 KHz carriers on the line which carries the voice and supervisory signals. The "metallic" customer is the one using the line in the conventional manner with a conventional instrument, while the "carrier" customer has his service out of a "subscriber carrier" unit. > The description implies a generator on > John's premises, which was powered from the phone system, and which he > added a power supply to when GTE switched it off. Yes, the unit is on the premises. It has a nicad which trickle charges off the DC on the phone line when the line is not in use by either party. The ring current, talk battery, and carrier encoding/decoding are all powered by that nicad. If the phone is used a lot, or for some reason that DC is not present, eventually the carrier subscriber's phone may not ring or even pull dial tone. Fortunately, there is a place inside the unit where one can hook up a 15V transformer and the unit then becomes independent of the DC on the line. > Also, his line was "converted to metallic"? Eventually, they had enough cable pairs in the area (by installing new cable) to give me one all to myself. > What was it before it was metallic - a piece of string with two tin cans?

(Dell Ellison) ---------------------------------------------------------------------- Date: Sat, 23 Sep 89 19:41:27 CDT From: TELECOM Moderator Subject: Conman Loses Prison Phone Privileges Readers of TELECOM and/or RISKS may recall a news report from about a year ago involving a plot to steal $69 million from the First National Bank of Chicago through a fraudulent wire-transfer scheme masterminded by Armand Moore. Using the telephone and computer -- the tools of his trade, Mr. Moore planned to transfer money from the accounts of corporate customers at First National to his account in Switzerland. He needed some inside help to bring it off, and he found two young guys in the wire transfer room at the bank who were willing to help. Both of the clerks were fellows in their early twenties, who had worked for the bank a couple years each. Both had come from families living in a ghetto neighborhood on the south side of Chicago; but their families had raised them to be honest. Both had been average high school students; neither had any previous criminal record of any sort; both had been given a break by an employer who treated them fairly and allowed them to rise to positions of trust: handling **huge** sums of money -- about a hundred million dollars a day -- in the wire-transfer unit at the bank. Both showed great promise; then Armand Moore came along. Moore wined and dined these two kids; showed them the best of times and what it was like to have a fancy apartment in a wealthy neighborhood instead of living with your parents in an inner-city ghetto. Its not that they weren't guilty -- after all, they did provide the secret passwords and phrases which bank employees say to one another on the telephone, and they did press the buttons which sent $69 million dollars on its way to Europe -- but they would not have done it if Armand Moore had not been there. So instead of a career at the bank, the guys exchanged it for an indictment for bank fraud; loss of their jobs; humiliation for themselves and their families; and the right to say 'convicted of bank fraud' on future job applications. Naturally, they are blacklisted in the banking and computer industries for the rest of their lives. One of the guys said Armand had promised to give him money to buy his mother a new coat. The job at First National was bungled as we all know, two young guys had their lives ruined, and the court took all this into consideration when Armand Moore was sentenced to ten years in prison last June. But as Paul Harvey would say, "...then there is the rest of the story...." It seems Armand Moore was no stranger to bank fraud. He had previously pulled a couple of smaller jobs, using a telephone and a computer to net about a million dollars from two banks in the Detroit area. The feds had not previously connected him with those jobs. He had this money stashed away, waiting for him when he got released from prison, which in this latest scheme, would be a lot sooner than the government expected. Mr. Moore is the sort of fellow who could sell the proverbial ice-box to an Eskimo.....or a newspaper subscription to a blind man....he can get *anybody* to do *anything* it seems....by flirting with them, showering them with attention, and if necessary, just bribing them. Now two more lives have been ruined by Armand Moore, and his only regret is he got caught. Since his trial in June, Armand Moore has been a guest of the government at the federal penitentiary in downtown Chicago. As a long term resident, he's gotten to know a lot of the folks, including the employees of the prison. In particular, he got to be very good friends with Randy W. Glass, age 28, an employee of the prison in the computer facility there. Glass' duties include entering data into the prison computer about the inmates, their sentences and other data. Oh...is the story becoming clearer now? Glass and his wife live in Harvey, IL, a middle class suburb on the south side of Chicago. It seems like so many other people who meet Armand Moore, Glass enjoyed the company of this older, very sophisticated and friendly chap. After several meetings in the past three months, Glass was finally seduced by Moore's money, like everyone else who meets him. That, plus his pleasant manners, his smooth conversation and his assurance that nothing could go wrong led to Glass finally agreeing to accept a $70,000 bribe in exchange for punching a few buttons on the computer to show Armand Moore's sentence was complete; him and a couple other inmates who were sharing the same room at the prison. Just change a few details, punch a few buttons -- and to be on the safe side, do it from home with your modem and terminal, using the Warden's password which I just happen to have and will give to you in exchange for your cooperation. $70,000 was hard to resist. But Glass was a prudent man, and he asked what guarentee would he have of payment once Armand Moore was released. After all, hadn't he promised those fellows at the bank all sorts of things and then tried to skip town immediatly when he thought the transfer had gone through? He would even cheat his fellow crooks, wouldn't he? Moore offered a $20,000 'down payment' to show his intentions. A confederate outside the prison would meet Glass' wife and give her the money. Then the job would be done, and following Moore's (ahem!) untimely release from the joint, the rest would be paid. The deal was made, alleges the government, and Armand Moore used a pay phone at the prison that day to call his stepsister and have her arrange to meet Mrs. Glass. The money would be exchanged; Glass was off two days later and would make the necessary 'adjustments' from his home computer; the prison roll would reflect this on the next morning's roster of prisoners with the notation 'Time Served/Release Today'. They would meet that evening and exchange the rest of the money. All telephones at the prison, including the public pay phones, are subject to monitoring. A sign on each pay phone advises that 'your call may be monitored by an employee authorized to do so'. The FBI alleges that recordings were made of Moore on the phone telling his stepsister that she should '...work with Randy, a person affilated with the law...' and that she would meet Mrs. Glass the next day. With a court ordered tap obtained a few minutes later, the FBI heard Stephanie Glass agree to meet Moore's stepsister at 5:45 AM the next morning in a parking lot in Richton Park, IL. At the appointed time the next morning, the two cars met in the parking lot, and the FBI alleges the one woman handed the other a package containing $20,000 in cash. The FBI videotaped the meeting and waited until Mrs. Glass had driven away. They followed her home, and arrested her at that time. Randy Glass was arrested at the prison when he arrived for work about an hour later. Armand Moore was arrested in his cell at the prison once Glass had been taken into custody. To do it the other way around might have caused Glass to get tipped off and run away. On Thursday, September 21, Mr. & Mrs. Glass and Armand Moore appeared before United States Magistrate Joan Lefkow for arraignment and finding of probable cause. Finding probable cause, she ordered all three held without bail at the prison until their trial. Randy Glass is now, so to speak, on the wrong side of the bars at the place where he *used* to work. He was suspended without pay at the time of his arrest. At the hearing, Magistrate Lefkow directed some particularly acid comments to Mr. Moore, noting that he was forbidden to ever use the telephone again for any reason for the duration of his confinement, and was forbidden to ever be in the vicinity of the computer room for any reason, also for the duration. She noted, "....it seems to me you continue to seek the conspiracy's objectives by using the telephone, and convincing others to manipulate the computer....you stand here today and show no remorse whatsoever except that you were caught once again. Your prison record notes that on two occasions, prison staff have observed you using the telephone and '...pressing the touchtone buttons in a peculiar way during the call...' and that you were counseled to stop doing it. I will tell you now sir that you are not to use the telephone for any reason for the remainder of your current sentence. I find probable cause to hold you over for trial on the charge of bribery of a government employee. Stay away from the phones and computers at the prison Mr. Moore!" Like Gabriel Taylor at the First National Bank, neither Randy Glass or his wife had any prior arrest record or conviction. In a foolish moment of greed, spurred on by a friendly fellow who Randy really enjoyed talking to '..because he was so smart and well-educated...' they now get to face prison and the loss of everything in their lives. When all three were leaving the courtroom Thursday, Armand Moore snickered and smiled at the audience. He'll find other suckers soon enough.
