Organization: Screaming in Digital, the Queensryche Digest
Rutgers University has an outlying campus in Camden, NJ. The campus
is in exchange 609-757, with some businesses. Since that exchange has
become full, the campus is being moved to a new exchange, 609-225,
which went into service on Friday (1/8/93).
Banners to this effect were placed on the campus dialins early this
week.
Within a day, several users of a public system at Rutgers had left
posts saying that they would no longer be able to call in for free,
because NJ Bell had told them the new exchange wasn't local to them.
Naturally, since the "localness" of a call is based on the distance
between CO's (at least in NJ), and the CO's were quite obviously right
where they'd always been, this caused a lot of confusion for the rest
of us, who were quite certain it would be a free call, as always.
It turned out that a scenario like this was being repeatedly carried
out:
User calls the operator to ask about 225.
Operator keys 225 into the computer.
Since 609-225 doesn't _exist_ yet, the computer decides that
they must (of course) mean 908-225, which is some 60 miles
away (and, coincidentally, a local call from a _different_
Rutgers campus).
Operator tells user that it's not local.
User panics.
When I called NJ Bell, and explained to the operator that it was a
Rutgers campus changing exchanges, the operator's response was, "Oh, I
remember when they did that up here in New Brunswick, it'll still be
local."
Convincing all the users who had been told by NJ Bell that it _wasn't_
local was a bit of a challenge, though!
When I mentioned this to a friend in Rutgers Telecom (T.P. Brisco), he
pointed out another bit of trivia:
"I understand when we split from 908-932 to 908-932 and 908-445,
that originally NJB proposed that we take the newly available
809 exchange (instead of 445). We rescinded that proposal on
the grounds that a phone number like 908-809-xxxx would lead to
too many typographical errors, and confusion with the newly
minted 908 area code. Maybe we should've asked for 923 instead
of 445?"
T.P. also posted a followup message mentioning that people had better
specify 609-225 when they called the operator.
I think all the users have caught onto the idea now, but there's bound
to be a few who stop calling in (particularly people from outside
Rutgers who just dial in to use the public system). Of course, those
few who continue believing it's a toll call after all our explaining
are probably modem-incompetent anyway.

I have sold a good few ZyXEL modems to various happy clients around
the world via our mail-server.
In one instance (and I suspect there are many more) the modems worked
fine, but would not answer when a call was incoming. This particular
instance was in Japan.
After a call to ZyXEL's tech support, they had a hidden register which
had to be set, and voil`a, everything worked just fine.
Recently, I noticed a posting in comp.dcom.modems in which a Swedish
ZyXEL user seemed to be having similar problems.
Is there such a great diversity in ringing current and ringing
cadences, other than the ringing in country code 1 and country code
44?
If there is a FAQ describing this, please let me know about it and I
will get hold of it. Thanks!

Subject: US Losing Lead in Telecom - USC Report
This report is from UPI:
Los Angeles -- America's traditional lead in telecommunications is
eroding very rapidly as other nations promote new technologies,
according to a study released Wednesday.
"The potential of new information communication technologies and
services is widely appreciated around the world and many nations are
making aggressive steps to promote their deployment," said the
University of Southern California study.
The study, produced by the USC's Center for Telecommunications
Management and covering 24 nations, found that the US lagged in a
number of key technologies compared with other nations, such as
converting analog networks to more efficient digital networks and
investment.
It said digitalization of the US network stood at just over 50 percent
at the end of 1991, which ranks ninth of 18 reporting countries, while
US investment in public network infrastructure was 12th among the 18
countries. It also said other nations were retiring used equipment
much faster than the US.
"While a number of other nations have dramatically increased their
capital investment in infrastructure, US investment is flat or
declining," it said. "Furthermore, depreciation trends in the US show
a shocking pattern."
The study added: "During this remarkable period of rapid technological
progress and obsolescence, asset lives for public network equipment of
local exchange companies have actually increased in the US. Nations
like Japan, the United Kingdom, Singapore and others write off and
replace equipment twice as fast as most US carriers."

Subject: Bellcore NPA/NXX Information
Reply-To: Al Varney <varney@ihlpl.ih.att.com>
Organization: AT&T
Patrick,
Several folks have asked for information available in some form from
Bellcore -- and my e-mail to them failed. Perhaps you could post this
AND include it in FAQ or archive. Thanks.
To Bob Larribeau at <p00136@psilink.com>, asking for NPA/NXX information:
Information about which LEC "owns" an NPA/NXX, and lots of other
data you might want, is in several Bellcore "products". For example,
the NPA-NXX V&H Coordinates Tape (primarily for billing) contains the
OCN (Operating Company Number) for each NXX -- you can translate that
to an LEC (or equivalent in Canada/Caribbean).
To Richard Cox, who asked for information on the NPA/NXX activity guide:
I tried to reply, but both <cix.comp@compulink.co.uk> and
<att!compulink.co.uk!cix.comp> didn't work; SMTP says 'compulink.co.uk'
is unknown.
-----
So, I've attached a canned response I use for questions about
Bellcore, but the telephone numbers correspond to the normal TR/TA
document center. The NPA/NXX information is maintained by the
(somewhat) separate Traffic Routing Administration (TRA) group, at +1
201 829 3071.
To complicate matters, there are three PUBLIC documents published
by Bellcore's document center, but maintained by the TRA. These are
available by contacting the document center as described in the
attachment.
- FA20: "Telephone Area Code Directory (TACD) Microfiche"
Contains all customer-dialable points in the North American Numbering
Plan with the corresponding NPA. Issued monthly. $50
- TR-EOP-000093: "TACD Paper Report" As above, issued annually around
September. Ordered by State and Locality. Carrier Identification
Codes are included.
- TR-OPT-001843: 800/900 List on Paper, giving company name and telephone
contact for each NXX assigned with the 800 and 900 codes. Issued
quarterly.
[Call the document HOTLINE in the attachment for prices of paper
documents.]
For all other TRA "products", or information about on-line access
to a database of routing data, contact the TRA Hotline at +1 201 829
3071, or write to:
Traffic Routing Administration
Bell Communications Research, Inc.
435 South Street, Room 1J321
Morristown, NJ 07962-1961
These non-public documents and on-line access require signing a
"Terms and Conditions Agreement" before purchase. You should ask for
a complete list of products and prices. Some of the documents do not
include Canada.
Some of the more "common-use" TRA documents are:
- NPA-NXX Vertical and Horizontal Coordinates Tape (the "V&H Tape")
is primarily for billing purposes, and lists (for each NXX) the type
of NXX, major/minor V&H coordinates, LATA Code, the ROA, Time Zone,
Place Name, OCN (TELCO) and indicators for IDDD and "Non-Dialable".
- NPA/NXX Activity Guide lists all NPA/NXX codes schedules to be added,
removed or "modified" (monthly). There's also an Active Code List
that lists all NPA/NXX codes that aren't planned to be removed or
"modified" for the next 6 months.
- Local Exchange Routing Guide (LERG)
contains information on all USA/Caribbean destinations, switching
entities, Rate Centers and Localities, Tandem Homing information,
operator service codes, 800/900 NXX assignments, etc.
(3 1600 BPI tapes!!!) Mostly useful to IXCs and other TELCos.
Good Luck,

Recently here (Strafford County, NH) a man was sentenced to four
months in jail for telephone harrasment for making two "hang up"
calls.
With this type of precedent, couldn't we give telemarketers at least
30 days (first offense...) and 800- number billing converters 5-10
years? :-) :-)

No, but AT&T announced yesterday that they're entering the Canadian
market via a modified partnership/investment arrangement with Unitel.
Unitel is presently a joint venture of Canadian Pacific and Rogers
Communications. Each will reduce their stake to 40% to give AT&T 20%
of Unitel in exchange for investment, market development, technical
expertise, and access to AT&T's American network.
Unitel President George Harvey commented that it was the right move to
make at the right time, that AT&T was a strong player in the world
telecommunications market, and that the arrangement would benefit all
parties.
He particularly stressed that the move would lead to faster, cheaper
communications throughout Canada, and that he expected rates to fall
quickly as new arrangements were made.
Unitel offers communications services in competition with Bell Canada
in the long-distance market, as well as private circuit facilities to
businesses (which has been their mainstay up until the present time).
It will be interesting to see what this venture brings. It will, at
the very least, be a significant change to the Canadian telecommun-
ications marketplace.
I don't work for Unitel, Rogers, CP, or AT&T. Nor am I a customer
(yet). But I did once work for Unitel's predecessor...

Reply-To: pedregal@cs.umass.edu
Greetings. I have a couple of applications for a device that flashes
a light (maybe even a strobe) when a plain phone line rings. Such a
thing must exist, but I can't find sources. Please email to me and
I'll summarize. Thanks!
Cristobal Pedregal Martin pedregal@cs.umass.edu

[Moderator's Note: The easiest way to do this is get a neon test thing
from Radio Shack (or anywhere else ...). Just wire it parallel to the
phone line. It does not draw enough current to take the phone off hook
but will flash in sync with the ringing of the phone. I have an
appliation here where there are several lines going into a computer
which is used for voicemail. No one wants to sit and listen to those
bells on the incoming phone lines ring all the time, yet it is very
important to know if for some reason the computer is not answering the
line ... with no bell it would never be noticed if something had gone
wrong. So, I have several 'beehive lamps' (the little plastic things
with a dome on top and a neon bulb mounted within) mounted on the wall
with double-sided tape. Wires run to each from the associated phone
line. They flash on for a couple seconds each time a call comes in on
that line. The only line with an actual bell on it is the final line
in the hunt group -- when it rings, it serves notice that the computer
has a full house, at least for the time being. I also have a little
counter installed on that line which increments by one each time that
line rings ... by viewing the register, one can see how often a full
house occurred since the last time the register was reset. PAT]

Maybe so. I, for one, would buy Caller-ID even if blocking applied to
99% of the state's telephones on a per-line basis. For me, the
telephone is an instrument whose purpose is to communicate with
friends, business associates, and customers -- plus people who could
potentially become one of these. ALL OTHERS are of no interest to me
whatsoever. Those who fit into the desired category of callers would
never block CNID to me; those in the undesired category can block all
they like.
I look at CNID as sort of a "wired PL". Just as there are many users
on some commercial two-way radio bands who stay out of each others'
hair by the use of "private line" encoding, CNID allows a similar
enhancement when using the public telephone network. You know that
when the phone rings, it is a "desirable" rather than a wrong-number-
idiot, a mysterious one-ringer pest, a hangup-when-you-answer creep, a
telesales slime, or even a former customer whom you wish never to hear
from again.
Now if I could just convince Pac*Bell that there are others like me
out there. Perhaps I could show them my e-mail ...

Sometimes that is quite proper. Tyranny of the majority, and all
that. And that's assuming "the majority" is _fully_ informed of the
