From: Eliot Moore <SWG.ELMO@USC-ISIB.ARPA>
Monday's Communications Week has an ad from British Telecom for what
appears to be the first 9600bps V.32-compliant modem to market.
Anyone in the position to review this beast please let me know your
findings. The ad mentions "remarkably competitive price" but fails
to enlighten us with the probable $3K figure.
Reference:
Model DM4962X Modem

Subject: Leased Data Lines
I am trying to get a data line between Tech Square and Harvard Square, a
distance of about 2 miles, except that the two ends are on different
offices. We would like to run 9600 baud or 19.2 if possible. Looking at
different modems, it seems that most of them call for either 3002 service
or 43401. The phone company has given me a quote on 3002 service, which
is a dedicated line with voice bandwidth and no DC continuity. This service
requires ~ $1500 modems to get 4800 or 9600 baud, but will work over an
entire metropolitan area. The local phone company has not heard of 43401
lines, although I have the AT&T document describing it, "Private Line
Metallic Service". This would allow us to use cheap line drivers and run
much faster, except that I can't seem to convince anyone at New England
Bell of what I want. It is basically just a pair of copper wires with no
amplifiers or multiplexing. What they are recommending is LADS (Local Area
Data Service), which I can't seem to find any technical information about.
Does anyone have any experience with this sort of data connection, and have
any recommendations as to what kind of service to get from the phone company,
or what modems to get? Thanx,
-Mark

Subject: private pay phones and auctioning spectrum
The July, 1985 issue of the North American edition of
"Telecommunications" carries an advertisement for pay phones by
Autelca
Autelca AG, Worbstrasse 201
CH-3073 Guemligen-Berne
SWITZERLAND
Telephone: + 41/31/52 07 45 ; Telex: 32123
They advertise 4 models:
Coin: "The coin payphone for rough and tough daily use"
Card: "The card payphone"
Duet: "The combined coin and card payphone"
Mini: "The coin-payphone for semi-supervised areas"
It appears that these instruments could be used either by operating
companies or subscribers who are providing private payphone service.
The same issue carries a "special report" stating, inter alia, that
the FCC has requested permission from Congress "[t]o award certain
communications licenses using an auctioning process to replace
lotteries. ... The call for an auction licensing process was triggered
by the Commission's continuing frustration with the traditional
comparative hearing licensing method -- a process that has long been
subject to charges that it is unwieldy, time-consuming, and only
marginally beneficial to anybody but lawyers."
