From: bob@bci.nbn.com (Bob Schwartz) Date: Tue, 22 Feb 94 15:49:33 PST Organization: Bill Correctors, Inc., Marin County, California This happened to me and I've never heard of such a thing. I have several lines and while talking on line line, which is hooked up to a fax machine and a phone (distinctly seperate stations), the phone integrated into the fax machine began to ring. then, right on que, the fax machine answered and my conversation was obliterated by fax tones The line has no special features such call waiting or three way calling. It does however recieve from a remote call forwarding source, but I can't see how RCF would have any involvement. Has anyone seen or heard of such an occurance and how could it be?

Darcos & Company, Silver Spring, MD USA In Pennsylvania, there is a company called "Snyder's of Berlin, PA, Inc" that makes potato chips. There is also a "Snyder's of Hanover, Inc", (PA) that makes potato chips. What do *both* of them use as the name for their potato chips? "Snyder's". Both of them, on their package, quite carefully, in small print, disclaim any relation with the other. Now, what does this have to do with telecom? Here's the situation. Winfred Ho, who lives in Ontario, Canada, is the author of a multitasking terminal program that runs on DOS based (not Windows) machines and provides the capabilities that would be associated with OS/2, including automated downloading, script capability, and the ability to run downloads or scripts in background while viewing and/or editing a text file. I consider the program to be about as important to me in doing telecommunications as my right arm, and when I don't have it I notice it right away; it so fit me perfectly that I didn't even wait 30 days from the first time I used it to register it. I am *extremely* fussy about telecom programs; I used the original Bitcom software for over five years because of more than a dozen comm programs I tried, every one was missing something I desparately needed, which, while I didn't like Bitcom, did what I needed. Then I found this program and it did everything I could want. The name of this program is "Telemate" and has been sold BOTH in the U.S. and Canada for more than five years. Recently someone else referenced here -- in response to a question about it -- what appeared to be a *totally different* program for a totally different purpose, that *also* uses the name Telemate. In the event the original poster wanted the name and address of the company that sells Winifred Ho's Telemate, here's the cut from the registration text file for version 4.12. In addition to being on many BBSs, this program can be found via an ARCHIE search, in four Zip archive files as TM412-1.ZIP through TM412-4.ZIP.

I have just received notice we have caller ID available in this area and would like to add it. However, I would like my computer to be able to receive the information. Is there such a thing as a CID box with RS232 output? The goal would be to use my voice card (Soundblaster) to announce the call. Better yet, is there a voice card with caller ID that could go in a PC and I could program software to interface with it? Any help is appreciated.

Are there any 'white papers' out there which gives an overview on PCS (Personal Communications Services)?

Hi, I am looking for infomation on pair-gain which is a technique of multiplexing (usually two) subscriber calls onto a single copper pair. The reason I need this information is that I wish to investigate if it could be used to improve the party line systems that we have in operation here in rural areas. Any e-mail information, suggestions or references that you could supply would be greatly appreciated, as I am battleing to find good reference material on the subject. Thanks. ------------------------------ From: chico!johnl@iecc.com Date: Tue, 22 Feb 94 18:15 EST Subject: Vermont Gets Ready For NNX Area Codes Organization: I.E.C.C., Cambridge, Mass. A flyer in my latest phone bill reveals that Vermont's new toll dialing plan is 1-802-NNX-XXXX, the same as will be implemented in Massachusetts. Permissive dialing starts on February 18 and ends May 18. Calling card calls must be dialed 0-802-NNX-XXXX, same dates. The flyer explains, fairly clearly, that they have to do this because NXX area codes are coming in 1995. Oddly, I still haven't seen any announcement of dates for the new dialing plan in Massachusetts. The new phone books that arrived this month (at every house except ours, for the 13th consecutive year) make no mention of it. NYNEX was originally planning seven digit dialing for all in-state calls. I don't know whether the state PUC required that they change, or that they did it voluntarily to be consistent with the rest of the region. In New Hampshire apparently you'll be able to dial either way, with a per-line option to block seven digit dialing of toll calls. Personally, I find the new plan to be a big pain in the neck, since, due to a peculiarity of exchange boundaries, it'll require that I dial most free local calls within our town with 11 digits.

The contents of its EPROM was destroyed due failure in power supply (+9 volts instead of 5) which I have fixed. Now the unit can not init itself and I can suppose the defective EPROM is at fault. I also have no manual and to find it and even the reset sequence would be great. Electric drawings and some descriptions seems to be not available but of corse wanted also. Hope on your help, many thanks in advance. Better reply by E-mail, I'll summarizse the answers.

Particularly, I am interested in cellular and mobile telecommunications. From what information I have gathered, the major players are NipponTT and AT&T. I have heard some reports of mobile telephones in Viet Nam. I believe they are not full GSM or AMPS cellular systems, but the CT2 phone system, with dial out only (no call receiving). Does anyone have any other information or experiences? Any info at all is appreciated. Countries in interest include Viet Nam, Laos, Cambodia, Thailand, Malaysia, Singapore, and Indonesia. Thanks!

In the UK, special rate numbers (free, cheap, and premium) all use any first digit, including 0 (usually long distance access), 1 (usually telecom services access) and 9 (often a short code prefix). For example, British Rail's express parcel service used to be 0800 000 000. Clive D.W.

A response said that > a lot of local switches would block 800-0xx and 800-1xx (ditto for > area 900), I don't believe any "local switches" are not capable of handling 1xx and 0xx office codes in a ten-digit number. These were/are routinely used to route early versions of INWATS and private network traffic. What many local switches are not capable of is supporting 0XX/1XX office codes in seven-digit translators -- a leading 0+ or 1+ is pulled off prior to looking at the translator. Supporting ten-digit calls of the NXX-0/1XX-XXXX form requires building a different form of digit translator to handle the office code (typically the NXX would just "point" to a seven-digit translator). > ... and it occurs to me: back in the 1970s, when 213 was the > only area code having N0X/N1X prefixes, did a lot of local switches > block 213-N0X and 213-N1X because they were "smart" enough to spot > that 0 or 1 in the middle digit of what should be the prefix? I was not aware any "local switches" blocked such inter-NPA calls. Obviously, until the NPA 213 switches were populated with information for routing seven-digit N0X/N1X numbers, they would fail to route them. You sure it wasn't PBXs blocking calls?

Subject: Call for Participation: Feature Interaction Workshop '94 Organization: PTT Research, The Netherlands Second International Workshop on Feature Interactions in Telecommunications Software Systems Amsterdam, The Netherlands May 8-10, 1994 PRELIMINARY PROGRAM and CALL FOR PARTICIPATION DESCRIPTION The feature interaction problem has been a major obstacle to the rapid deployment of new telephone services. Telecommunications software is huge, real-time, and distributed; adding new features to a tele- communication system, like adding new functionalities to any large software system, can be very difficult. Each new feature may interact with many existing features, causing customer annoyance or total system breakdown. Traditionally, interactions were detected and re- solved on a feature by feature basis by experts who are knowledgeable on all existing features. As the number of features grows to satisfy diverse needs of customers, managing feature interactions in a single administrative domain is approaching incomprehensible complexity. In a future marketplace where features deployed in the network may be developed by different operating companies and their associated ven- dors, the traditional approach is no longer feasible. How to detect, resolve, or even prevent the occurrence of feature interactions in an open network becomes an important research issue. The feature interaction problem is not unique to telecommunications software; similar problems are encountered in any long-lived software system that requires frequent changes and additions to its func- tionality. Techniques in many related areas appear to be applicable to the management of feature interactions. Software methodologies for extensibility and compatibility, for example, could be useful for providing a structured design that can prevent many feature inter- actions from occurring. Formal specification, verification, and tes- ting techniques, being widely used in protocol engineering and software engineering, contribute a lot to the detection of inter- actions. Several causes of the problem, such as aliasing, timing, and the distribution of software components, are similar to issues in distributed systems. Cooperative problem solving, a promising approach for resolving interactions at run time, resembles distributed planning and resolution of conflicting subgoals among multiple agents in the area of distributed artificial intelligence. This workshop aims to provide an opportunity for participants to share ideas and experiences in their respective fields, and to apply their expertise to the feature interaction problem.
