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?

Organization: Tansin A. 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.

Subject: Caller ID Box With RS232
Date: Tue, 22 Feb 1994 14:33:54 EST
From: Daniel Wynalda <[email protected]>


I'm sorry -- I'm sure this is a FAQ as I've seen it before.  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)?  I have seen alot of articles on
the service over the last few months, but I would like to have one
definitive document which gives an overview and possibly a listing of
some of the companies which are driving this.

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.

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.

Hi friends,

Please help me find EPROM text for MURATA M3 Fax unit. 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.


Sincerely,

I am performing research on the telecommunications in Southeast Asia.
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.

  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).

  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?

Where can I get more information about connecting a PBX or telephone

manufacturers?  Who do you recommend?

If you're willing to chat with me about this, drop me an e-mail with

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.
