Subject: Now Anyone Can Have ANI on Their 800 Number
Date: Fri, 4 Mar 1994 16:57:48 EST
If you are interested in receiving REAL-TIME ANI on 800 calls to your
Voice Response system, regardless of whether your calls are coming in
on T1, Loop Start, Ground Start, or otherwise, read on ...
Working with a client of mine, we have developed a method whereby
anyone with a VRU that is direct dialable from the United States can
receive the ANI of the caller, as well as the 800 number that was
dialed, prior to conversing with the customer. This does NOT rely on
Caller-ID, ISDN, or any other out-of-band type of signalling. It is
really quite simple ... as soon as your VRU answers the ringing line,
the DNIS and ANI will be outpulsed to the VRU using DTMF tones. If
your VRU does not receive any digits within the first three seconds, it
can provide a default prompting scenario. This would happen if
someone called the VRU directly, instead of through the 800 number.
For more information, please contact me at the email address listed
below, or call me at 609-698-7044 X201.

Subject: Followup on C&W CID in NY and CT
About a day after I posted an article on how C&W doesn't appear to be
delivering ANI -> CID in New York and Connecticut, it suddenly started
working again, but only in NY.
Our software pages me with remotely with the CID of who called, so you
can bet I was suprised when I got a call via a C&W 800 number in NY
where the ANI -> CID was sent to my pager and it showed a number in
Atlanta! I thought it was something wrong with the computer, or maybe
that someone had paged me by mistake, but when I got down to NY and
checked the CID box, it did indeed have the number from Atlanta.
Further tests confirmed that ANI -> CID was indeed working again.
I said "Wow! That was fast -- someone must have read the post and
'fixed' problem!". But, when I tried to get the CID from C&W in CT
(where it had worked in the past), all I get is still "Out of Area :( .
Also, after some testing, I noticed that the CID to NY works from most
areas of the country, except for New England. You don't get ID's from
Rhode Island, Mass, VT, NH, or Maine. I didn't try Canada yet, but I
suspect that at the very least Quebec won't work either (it did previously).
So it's working again -- sort of. Thanks to anyone at C&W who may have
read my earlier posting and fixed the problem.

A major challenge of this decade is the effective exploitation of two
symbiotic technologies: portable computers and wireless networks.
Harnessing these technologies will dramatically change the computing
landscape. But realizing the full potential of the resulting mobile
computing systems will require advances in many areas such as:
hardware communications scalability power management
security data access user interfaces location sensitivity
The goal of this workshop is to foster exchange of ideas in mobile
computing among workers in the field. Attendance will be limited to
about 60 participants, based on the position papers submitted.
Submissions should be fewer than five pages in length and may expose a
new problem, advocate a specific solution, or report on actual
experience.
In addition, we will be hosting a small number of novel hardware and
software exhibits relevant to mobile computing. The exhibits may be
research prototypes or commercial products. Interested parties should
submit technical descriptions of their exhibits.
Online copies of the position papers will be made available via
anonymous FTP prior to the workshop. A printed proceedings will be
published after the workshop, and mailed to participants.
A small number of graduate students will be granted a waiver of the
registration fee. In return, these students will be required to take
notes at the workshop and help put together the proceedings. Students
who wish to be considered for the waiver must send in a brief description
of their current research, and an explanation of how participation in the
workshop is likely to help them.

Subject: Fax on the Net - Impact on Telcos?
Date: Fri, 4 Mar 1994 13:32:23 PST
I've just started looking into the developments in fax gateways via
the Internet. I know there are a number of commercial services
available, and of course there are fax/modems and software available,
but I'm talking about the *non-commercial* avenues available, such as
the TPC project lead by Carl Malamud (of Internet Multicasting
Service) and Marshall Rose (of Dover Beach Consulting, Inc.), and of
course, Dr. Robert Riley's Digital Chicken experiment which covers the
Toronto area.
My question is this: How is this going to affect the telcos? It seems
to me that as the Internet grows in popularity and use, people will be
seeking options such as these, rather than mere discount fax plans.
What's the scoop?

There was a movie produced in the fifties, probably patterned
after "The Desperate Hours" in which a couple of thugs terrorize a Las
Angeles family for a day or so.
In the movie, one of the hoods modifies the radio in a car to
receive the LAPD. The criminals also place several telephone calls
which the police frantically try to trace.
In one scene, a technician is following the call through rack
after rack of steppers, hoping that the call won't be disconnected
before he can follow it through.
As a telecomm enthusiast, I was impressed with the technical
authenticity of the film, but I don't remember its name. Before the
mid sixties, the Las Angeles PD was on 1735KHZ and was often audible
in Oklahoma around midnight, especially in Winter. In the scene where
the telephone technician was tracing the calls, one could hear the
rata-tat-tat of steppers and the zzzzip of the resetting relays when
the call tore down. One of the exchange names in the trace was
Dunkirk.
Does this movie sound familiar to anybody?

These aren't totally telecom-related:
1. In the movie Electric Dreams, the protonist Miles [Lenny Von
Dohlen] who lives in San Francisco, California purchases an Acorn
computer to help keep his schedule in order. When he's unpacking the
computer, it has European two pin style 220 volt plugs. In one scene,
they do have US style baseboard 110 volt outlets with adaptors for the
computer's plugs. Miles accidentally spills champagne in the
computer, causing it to take on an anthropomorphic personality. The
computer falls in love with Miles' neighbor [Virginia Madsen] who is a
cellist. At one point, Edgar the computer calls Miles' pager while he
is at a concert and serenades the cellist with Tchaikowski via the
pager. It is a silly movie but rather fun for computer nerds.
2. In one of the Pink Panther movies (I forget which), Clouseau
[Peter Cellars] is tracking Lady Litton in Switzerland. He's playing
a bell boy delivering room service to Lady Litton's room. He's trying
to remain stealthy when a lightbulb pops out of a table lamp. He has
to catch the flying bulb so it doesn't break, rousing Litton's
attention. He tries to put the bulb back in the socket repeatedly,
but it keeps flying out.
The movie is probably primariliy aimed at US movie audiances, but I
doubt they understand the joke since here in the US we have Mazda base
bulbs, which thread into their sockets. European bulbs have bayonet
type sockets (similar to over-grown automotive turn signal lamp
sockets) so the gag makes sense if you understand this. The US
neophyte would think the joke dumb as there's no way a screw-in bulb
would pop out that way.
Well, there is an error in that scene where the mechanical device that
makes the bulb pop out of the socket is clearly visible in one of the
takes. I remember seeing it the first time I saw the movie and wasn't
in the pick-it-apart mode.
There are a number of cheesey monster movies and the like where the
sytle of the telephone instrument doesn't match the country there the
action is supposedly taking place.

I wonder if 2400 baud is being taking literally or figuratively? BAUD
is signaling states. BPS is something different and is some integral

This may be a trick question, or it may be somebody at NYNEX using an
old line.
No commercial modem today runs above 2400 baud on the phone line. BY
definition, baud is the inverse of the signaling interval; even 14.4
kbps modems only send 2400 symbols per second, but each symbol encodes
six bits, so they are only 2400 baud! The data terminal interface, of
course, may be serial at the higher rate.
If they're not being so literal, then it's true that they
traditionally treated phone lines as "voice" and thus considered 2400
the top modem rate. But today's 9600 bps modems are about as tolerant
of line quality as yesteryears' 2400 bps modems; even faster speeds
will usually work. They just don't _guarantee_ it. Cape Code has no
electromechanical central office switches left, either; it's all
modern stuff (a few 5ESS switches with a bunch of remotes, mostly).
Unless they're very far from one of the wire centers, the phone on the
Cape are as good as anywhere.
