Sirbu, Jr." <SIRBU @ MIT-MC> Subject: TELECOM Digest V4 #139 To: TELECOM @ BBNCCA The service being tested in Orlando is being offered on an ordinary #1ESS. The reason for selecting Orlando is that, for the caller's number to be displayed ALL the switches in Orlando from which calls originate must be equipped with the appropriate software generic. Orlando is one of the few cities in the country where there are NO electromechanical switches still in servce -- everything is SPC. (Harrisburg, Pa is another such city which is why a similar test is being conducted there). The service being tested also requires the equivalent of CCIS (common channel signaling) between all of the local central offices to convey information such as the caller's number from the origin office to the final office. The special equipment needed to receive caller's numbers at the called number location essentially provides a CCS channel all the way to the customer. Lot's of interesting services will be possible when CCS channels are widely available to customer locations, as is planned for in ISDN standards.

I've reported this to GTE on the trouble number, they've supposedly checked things out and found nothing. Any ideas on what this could be? Could it possibly be my cheep phone?

I would like to state that I am not affiliated with ANY of these companies, and I am not receiving and benefits by posting this information! After spending a few days pricing modems I have compiled the following information (saving the best for last). If anyone has any additional information I would greatly appreciate it. We were interested in rack mounting them so most of the prices given are for cards that would plug into a rack. "box" refers to a stand alone modem.

The list price for the Stand Alone (box) modem is $ 795 The list price for the (rack) mounted modem is ~$ 700. Besides starting off $ 200 less than everyone else their quantity discounts are very good. The Stand Alone modem will be available starting January, and their rack mount modem should be available February. Here is a Quantity discount price list. Quantity %dicount S.A. rack ======== ======== ==== ==== 1 list $795 $700 2-5 10 % 716 630 6-10 20 % 636 560 11-25 25 % 596 525 25- 30 % 556 490 For all of you usenet sites that are still running 1200 (or possibly even 300) the modems will pay for themselves very quickly. From all of the literature that I have recieved here are a few of the advantages of this modem above the others: 1) works at 300 or 1200 or 2400 asyn (others only 1200/2400) 1200 or 2400 sync 2) Stores 10 numbers (40 chars each) (others only 1) 3) For tone dialing it dials ALL 12 (others only can generate tones including (* and #) numbers 0-9) This last one caused a nasty problem when we needed to generate the extra tones because some of the sites we talk to have switching systems that require them (Gandalf). 4) Will automatically change the speed (some of the others needed to the other modem. a manual intervention). --------------- usenet: {philabs, allegra}!sbcs!bruce Bruce Factor ------------------------------ Date: Sat 29 Dec 84 19:36:20-EST From: Andrew Moore <T.MOORE%MIT-EECS@MIT-MC.ARPA> Subject: Phone Surveys by Computer To: TELECOM@BBNCCA.ARPA Could someone explain how these phone surveys done by computers work?? I just got a call from one, and it wouldn't hang up if I put the phone on hook for a while, so I gave it (her?) a carrier tone and it tried to connect to my modem and then hung up. -dru ------- ------------------------------ To: telecom@BBN-UUCP.ARPA Subject: Equal access carrier codes Date: 30 Dec 84 00:32:18 EST (Sun) From: Mike O'Brien <obrien@CSNET-SH.ARPA> In the wonderful new world of equal access, where you can select your long-distance carrier differently for every call, there are assigned codes for a whole bunch of new long-distance carriers about which I basically know nothing at all. Some require that you sign up with them before you use them; some say you can use them at will and your calls will appear on your next bill. Can anyone tell me where I can get a list of all valid equal-access codes and the carriers they represent, together with an indication of which require prior sign-up and which you can just go use? ------------------------------ From: ihnp4!utzoo!henry@Berkeley Date: 30 Dec 84 00:40:34 CST (Sun) To: telecom@bbncca.ARPA Subject: new 2400-baud modem from R-V > ...

Strangely enough, other phones in the area, including my second line, did not show similar symptoms. Also the phone worked perfectly for dialing out. So, after the problem did not go away I reported it on the 27th, and was told that I should not expect anyone to check it out until the 31st or later. On the 28th, I decided that I was less than satisfied with that response time, which basically meant that noone would be able to reach me either for X-mas or New Year's as noone knows my second number. So I decided to inquire if it would be possible to put a recording on my first line, informing of my 'new' number, or to enable call-forwarding for the duration of the problem. Not surprisingly, really, I got the run-around, noone seemed to understand what or how to achieve the effects I desired, Repairs and the Business Office of Southwestern Bell gave me 'circular references' to talk to the other. Calls to me were not made or returned, as was promised, until, late Friday, a 'new voice' called, informing that it was all a computer error, which had caused the problem on several lines. When asked for more info on the problem, the person could not give more, as 'that was all she was told'. I intend to try to dig around some more and find someone to talk to who can give straight answers, but in the meantime, if anyone out there could add some factual knowledge to what might be going on here, or how one might penetrate the front-people of SouthWestern Bell and which department or job-title to ask for to get answers, mail me. One other "strange" matter: lately, I had noticed a strange ticking sound on that line, as well as a wooshing-sound, kind of like a tape-recorder, which has since disappeared. Could it be that I had been bugged ??? ------- ------------------------------ Date: Mon, 31 Dec 84 12:30:57 EST From: Carl Moore (VLD/VMB) <cmoore@Brl-Vld.ARPA> To: telecom@Brl-Vld.ARPA Subject: old use of 511 in Phila.
