TELECOM Digest is an electronic journal devoted mostly but not
exclusively to telecommunications topics. It is circulated anywhere
there is email, in addition to various telecom forums on a variety of
public service systems and networks including Compuserve and America
On Line. It is also gatewayed to Usenet where it appears as the
moderated
newsgroup 'comp.dcom.telecom'.

Subject: More Administrivia, Errors, etc
<Face red mode> ... *if* you chose to pick up a copy of the 1992-1994
volume of the Accelerated Index from the archives .. well, there was a
slight error in the way some items were keyed ... I found out when
someone using the SEARCH command of the Email Information Service
contacted me to say they were getting quite screwey answers in
response to some searches he was making ...
It was only announced yesterday, so most of you probably have not yet
picked up a copy, and in all probability most of you will not want
to bother keeping this humongous, 26,000 (yes twenty six thousand)
line file at your site. But if you did take a copy prior to Wednesday
at about 6:30 PM CST, do me a favor ... ditch it and go get another
copy, one that has been corrected.
What this is -- when it works correctly, as it is now -- is a complete
index of the titles of articles which have been in the Digest for the
past six years and the author names. You can either use SEARCH, which
is a command in the email server, or you can simply go and pull the
two files back to your site. There are two editions. One covers the
years 1989-1991 and the other covers 1992-1994. Together, they
constitute
about 48,000 entries, the number of messages seen here over the past
six years. They are sorted in strict alphabetical order by subject
with
any instances of 'Re:' where it appears ignored for the purpose of the
sort. Where more than one article appears with the identical subject
title, the sort continues further by author *first* name. When using
grep or SEARCH (which is just a version of grep I put in the email
server) you can search by subject name or author name. It is highly
recommended that you use the most liberal grep possible, that is,
with '-i' as the argument, so that case will be ignored. Also, if you
choose to search by author, search the *last name only* since
sometimes
the first name appears as just an initial, i.e. P.Townson.
If you are really interested, use the INFO command in the email server
to get two other files you'll need to interpret the rest of the data
shown in the accelerated index:
INFO back-issues
INFO search-hints
Anyway, that's enough on the topic. I botched it, and I've repaired
it, I think. I'm sure someone will tell me if that's not correct.
-----------------
In other administrivia news:
I've received a suggestion from a reader about having a 'human
resources'
section in the archives. This would be a place where anyone who wished
to do so could put a paragraph or two about themselves for the benefit
of other readers. It would be voluntary and would have no connection
at all to the mailing list, which is never shared or revealed.
Suggestions for things to include would be in addition to your name,
address, phone number and company/school/institutional affiliation,
perhaps a .signature file, a paragraph about your current project(s),
prior accomplishments, etc. It would be removed/destroyed from the
archives whenever you said to do so, or modified as required.
*DO NOT SEND ENTRIES NOW*
Just let me know what you think of the idea, and if you would want to
have data about yourself there in the Telecom Archives.
Should it be open and available to all to read? I can fix it so that
it is blocked or denied to FTP/Gopher users while available on a
passworded basis to email service users. If it is open to all to read
you can be sure of receiving lots of junk mail ... :) If on a
passworded basis, then only those who contribute entries of their
own would get the password to read the biographies of the others ...
in other words, give a biography of yourself, and read the others.
Let me have your thoughts. *DO NOT SEND ENTRIES NOW*.

Call for Papers
ISLIP'95
The Eigth International Symposium on Languages for Intensional
Programming
May 3-5, 1995, Macquarie University, Sydney, NSW, Australia
Objectives
There is a growing interest in computational models and/or programming
languages and systems based on intensional logics such as temporal
logic, interval logic, modal and intuitionistic logics. In fact, a
whole new programming model called intensional programming has been
created with applications in a wide range of areas including parallel
programming, dataflow computation, temporal reasoning, scientific
computation, real-time programming, temporal databases, spreadsheets,
attribute grammars, and hardware synthesis.
This symposium aims at bringing together researchers working in all
aspects of this area, and to promote intensive discussions and foster
collaboration among researchers. We encourage papers dealing with the
theoretical foundations, design, implementation and prototype
development issues, comparative studies, and applications, as well as
those describing new challenges arising out of applications.
The symposium will include, but will not be limited to, the following
topics of interest (as they relate to intensional programming):
Programming paradigms Semantics
* dataflow computation * non-determinism
* connectionist models * extended Kahn principle
* logic programming * intensional concepts
* real-time programming * termination issues
* languages such as Lucid and GLU
Software Engineering Applications
* version control * signal processing
* visual user interfaces * image processing
* parallel programming * hardware synthesis
* fault-tolerant systems * graphics
* program verification * data models
Submissions
You are invited to submit either a full paper or an extended abstract
of approximately 5000 words (10-15 double spaced pages). The cover
page should include the name, phone/fax numbers and e-mail addres of
the contact author(s), a short abstract, topic(s) and a list of
keywords. Papers will be reviewed by the program committee for their
originality, correctness, significance, and relevance to the
symposium.
We prefer PostScript or self-contained LaTeX submissions via
electronic mail to either one of the e-mail addresses below. You can
also send 3 hardcopies of your submission to one of the following
addresses (chosen with respect to geographical proximity). Submissions
should arrive no later than February 15, 1995.

Authors will receive notification of acceptance by March 20, 1995.
Revised versions of the papers to appear in the pre-proceedings to be
distributed at the Symposium are due on April 12, 1995 (preferred in
PostScript or LaTeX form, sent by email). The symposium will be held
on May 3-5, 1995 at Macquarie University, Sydney, NSW, Australia.
At the Symposium, the research will be presented and also evaluated,
and it is planned that final polished papers will appear in the
proceedings in book form.
The details about registration and accommodation will be provided
later.

The GSM book that seems to be most popular is:

It is a private printing - you have to contact the authors on number

I have nothing to do with the authors and do not get commision. Which
is a shame, as I've recommended it quite a bit <G>
Does anyone know of a US distributor ? (I suppose there may be copies
on sale at CTIA or Wireless ?)

Anyone know about the following companies:
American Management System
Systemetic Inc.
Both companies specialize on Telephone Billing Systems. We need to
know their US contact and also their Rep Office in HK or SE Asia.
Suggestions on how to find such information are also welcomed. (e.g.,
sites where I can find out the address and telephone number of any US
companies, etc.)

According to the AT&T 1-800 line they only have four exchanges

Canadian federal government offices in Vancouver BC have been on the
666 NXX for years. This included (at last report) the regional office
of the CRTC which regulates telecom and broadcasting in Canada.

And our IRS analog, Revenue Canada, would certainly have an office in

This isn't quite true. With all circular hunt trunk groups I know of,
the decision of whether or not to route advance to the next group is
done each time a call origination is received. So if a trunk in the
primary group is free at the time, it will get the next call.
Circular hunt on primary high-alternate use combination does provide
signficant benefits, especially if per trunk signaling is used.
Circular hunt, if designed to always start hunting at the trunk
following the one just picked, significantly decreases the impact of
killer trunks on traffic capacity of the trunk group.

FYI The local cableco here in Fairfax County, VA (Media General Cable)
has a 10XXXX code (106-500), used for ordering Pay-Per-View movies. I
can't seem to get an answer from Bell Atlantic on how this was
arranged. Is this a common practice, I wonder.
