Subject: Using Call Forwarding to Avoid Tolls
Date: 27 Apr 1994 10:50:34 -0400


I've recently become aware of the fact the many BBS's and Internet
service providers use the call-forwarding trick where they go buy a
phone number (without a phone) in outlying exchanges which are
permanently call-forwarded to their main lines, thereby increasing
their local call area.  Apparently some of them carry this to the
point of multiple forwarding, which may get them 50 or 75 miles
without a toll.

I was just wondering how the phone companies feel about this.  Is this
something that you can just tell them you want to do, being very open
about it?  Or do you need to sneak around, get the numbers in different 
names, etc?

Also, assuming that this is legal and acceptable, can you forward
multiple calls off of one line, or do you need one line per call?

Thanks in advance for any help.


Tom Holderby    holderby@gate.net


[TELECOM Digest Editor's Note: Generally, using the *regular, residential
variety* of call forwarding will NOT save money where toll charges are
concerned unless you are able to link two or three large toll free calling
areas together. Generally, two or more short calls linked together cost
more than a single long-haul call covering the same points. There is a 
service offered by many telcos called 'remote call forwarding' which con-
sists of a phantom number in a central office with no actual wire pair
going somewhere attached to it. This phantom number is programmed perman-
ently by telco to automatically 'call forward' to some other location 
outside the CO. The subscriber pays for those calls at the direct dial
rate in effect at whatever time a call is received. Remote call forwarding
usually requires a 'path' for each call to be forwarded at the same time.
You want to be able to receive three calls at once, you need three paths,
etc. 

This often times is not intended so much to save money for the caller
as it is intended by the called party to provide a local presence in
the community where the caller is located. Remote call forwarding is
legal and a published tariff. On the other hand, the casual stringing
together of phones in a call forwarding link purely for the purpose of
toll-avoidance is not legal; but more important, it rarely can be
justified economically with the exception mentioned above of phones in
large toll free areas which have been *very* strategically placed at
certain locations. As long as they buy the line 'without the phone'
from telco according to remote call forwarding tariffs (they are NOT
priced the same as regular call forwarding tariffs) then it is legal.
Subscribers who elect to use this really need to sit down with pencil
and paper and work out the costs before proceeding to see if it makes
any real difference or not to them and their subscribers before
proceeding. It might if they are large like Compuserve.  PAT]

Subject: Reach Out and Touch Someone ...


The following is a reprint from the May 1994 issue of {Worth Magazine}.

Shady Operators

A new measure would mean phone callers don't have to put everything on
the line.

How would you feel if your telephone company were to sell your name and
address to a travel agency because you make lots of international calls?

What if it gave your name to an X-rated video marketer as part of a
list of phone-sex addicts?

Though they haven't been hashed out in court, such actions are likely
legal right now. Phone companies aren't barred from hawking lists of
names, organized by calling habits, to all comers. Meanwhile, police
departments and other authorities need a subpoena to see such records.

Most phone companies insist they'd never divulge your habits to a
marketer -- although they may use them for their own marketing purposes.
But many other companies sell phone-call records: Mail-order companies, 
for instance, often use caller-identification technology that tells them 
who's calling, then sell that data to other merchants.  And some
numbers exist just to gather mailing lists.

"A great deal of information about us is collected, analyzed, and sold
when we are conducting everyday activities," says Congressman Edward
J. Markey of Massachusetts, who's pushing a measure to limit info
harvesting.

Markey's proposal, included as an amendment to a broader telecommunications 
bill, seems like a no-brainer: It would mainly require phone companies to get 
a consumer's express consent before disclosing any calling patterns or
other data. The bill also would set nationwide privacy standards for
caller-identification technology and require new privacy rules for all
telecommunications media.

But powerful local phone companies oppose the measure, which will
likely be debated in the late spring. "The telephone business has been
around for more than 100 years, and sacrosanct privacy has always been
its hallmark," says a spokesman for BellSouth. "It seems strange that
anyone thinks legislation like this is necessary."

Organization: Chesapeake Bay Information Systems


I recently purchased a surplus AT&T Craft Access Terminal for use as a
telephone test set -- a function it fulfills quite adequately.
However, I would like to be able to use the "Craft Access Terminal"
part as well -- it'd be a nifty handheld data terminal, for instance.

Using the CAT, I dialed into one of the modems around here and
discovered that the set features a 1200 baud modem, which connected
quite readily with my own AT&T DataPort.  However, I could do nothing
more.  The CAT sends out a steady stream of ESC-LF-LF-LF-LF-ACK-NUL-NUL 
(pause) as if it's expecting a reply from the other end.

Anybody familiar with AT&T's Craft computers or CAT test sets?  I'd
appreciate follow-up here or by email.


Thanks!

That is correct; we've found the same problem with ring no answer
situations.

Of course, there is a second cellular carrier in the Bay Area <g>, and
it *does* handle call supervision correctly.  Additionally, almost all
of its roaming partners are on the NACN, and call waiting works in
almost all of them.

Organization: University of Delaware


I came across few references quoting proceedings of International
Switching Symposium (ISS) for 1990. Since the library where I am does
not have these proceedings, I requested inter-library loan in my
location.  But, the problem is that the inter-library loan office in my
location is unable to locate these proceedings.

I consulted so called I.S.T.P. (? I forgot exact acronym) which is a
manual with cross-references of all (?) technical conferences held
around the world, and I failed to find this so called International
Switching Symposium.

Now, it is more of my *curiosity* than need.  Can somebody knowledgeble 
tell me where to find (library/institution) the proceedings of Interna-
tional Switching Symposium?  Does your library has proceedings of ISS?
If so, what years?

Please email to shin@udel.edu.  Thanks for attention and time.

Subject: Incident Management Call Boxes
Organization: Tansin A. Darcos & Company, Silver Spring, MD USA


In another news group, a representative of North Carolina State
University wanted some information about costs and usage for setting
up a system of roadside call boxes for freeways, as they've been asked
to do so by the State.

Someone else pointed out that the Texas Department of Transportation
created a callbox system on freeways in the Fort Worth/Dallas area;
the system uses cellular to call 911.

The writer from Texas pointed out that "the system does not allow
calls to anywhere else."  It was at this point that I mentioned the
incident in Southern California where one call-box unit was either
stolen or monitored to get its identification code, which was used to
cause tens of thousands of dollars in fraudulent cellular calls.

I am wondering if there isn't some sort of "dispatch/reply" system
that would use several shared radio frequencies along with a "request"
channel where someone would send in an identifier and then be told
what frequency to tune to?  Someone could have perhaps 10 channels and
use them as needed, instead of paying airtime and usage of a cellular
network, or some other ideas.

Responses may be made to me personally (I'll forward them), to TELECOM
Digest or to list <transp-l@gmu.edu>.  Thank you for any responses.

Organization: PC-OHIO PCBOARD - Cleveland, OH - 216-381-3320


For the past few years, I have been writing script files in xtalk for
interfacing to Northern Telecom PBX's.  We currently have Option 11's
at our remote sites, and an Option 61 at our RHQ.

I was wondering if there is any market out there for such a product,
or if it is even possible to sell them without permission from
Northern or Xtalk.  I would imagine that it would at least have to
include the old, "NT is a trademark of Northern Telecom ... blah,blah".

So far, I have written scripts for menu-driven programming changes, 
(changing phone features, setting date and time, and some misc), an
automatic NPA,NXX updater for NARS/BARS equipped switches, A DTI/T1
interface monitor, which alerts my pager of a t1 outage,(outages
effect my actual bonus $) or high error rate, an automatic phone
TRACer, and some other misc shtuff.  I am currently writing one for
doing automated remote backups of all of our Option 11 switches on a
monthly basis which would save time and money for visits to the actual
site for P.M.'s.

I am also planning to add all of these routines into a single script
file, that is upgradeable by adding specific modules. I was also
writing one to alert my pager of the actual load that is seeing a
problem, such as 911-60 for a T1 outage or 911-32 for a set outage.

Well ... just curious and looking for input.  I would hate to write
all of these, and not let anyone else have the opportunity of using
them.

I'm interested in some of the technical specifications of True Voice
by AT&T.  Is it another method of companding the signal to get better
sounding voice?  I got the feeling that it only works between
subscribers that are both AT&T.  The ads say it is part of the I-plan
and I suspect it is a bit of a ploy to get family members to join AT&T
like MCI's friends & family.

Most importantly, does it mess with data transmission?  I would
suppose it changes the channel characteristics.

FIRST SMART CARD RESEARCH AND ADVANCED APPLICATION CONFERENCE

October 24 - 26, 1994  LILLE FRANCE

Sponsored by IFIP - The International Federation for Information Processing

AIMS AND GOALS

Smart cards or IC cards are becoming a significant part of the
information processing world. Furthermore they are beginning to move
towards real integration into the information systems. They
participate in the overall data management, security and communication
processes. But they bring their own special characteristics. It is
very likely that future IC cards will require many scientific and
technical improvements which represent a challenge for the success of
the technology. So far there are many events which are mostly devoted
to the commercial and application aspects of IC cards. There is now an
opportunity to initiate a scientific conference bringing specialists
who are involved in all aspects of design of the future IC cards and
related devices and environment. IFIP - the International Federation
for Information Processing has agreed to sponsor this conference. It
will be the first occasion for the IC card community to start a
permanent activity: In addition to the conference itself there will be
discussions about creating a permanent group within IFIP with possible
implication for advancing standards, publishing and international
cooperation.

SUBMISSIONS

Six copies of detailed abstracts of original papers corresponding to
one or several themes for the conference should be sent in English to
the program chairman before May 2, 1994. The submissions will start
with a succinct statement of the problem addressed and their
significance, appropriate for a non-specialist.  Technical development
directed to the specialist should follow as needed (at most ten
pages).

They should be accompanied by a fact sheet indicating the following:
  - Title of the paper with the relevant conference theme(s);
  - Author(s) with affiliation, address, phone and fax numbers, E-mail.

Proceedings will be available at the conference.
