SAN JOSE, CALIF. (MARCH 7) BUSINESS WIRE - March 7, 1994 -- Continuing
its work to fulfill the vision of any time, anywhere communications,
Motorola today unveiled the Envoy(R) product, the first fully
integrated personal wireless communicator that incorporates two-way
wireless and wireline communication. The Envoy communicator, the first
in a line of personal wireless communicators from Motorola, was
demonstrated at an event held in conjunction with the opening day of
the Mobile '94 Conference in San Jose, Calif.

Based on General Magic's intuitive Magic Cap(TM) platform and
Telescript(TM) communications language, the Envoy hand-held device
lets users instantly access and communicate information anywhere --
across a conference table or in a moving taxi.  It is powered by
Motorola's Dragon chip set -- the highly integrated 68349 processor
and a special purpose application specific integrated circuit (ASIC)
referred to as Astro.  This chip set was designed specifically to
optimize the performance of Magic Cap and Telescript.

"It's rewarding to witness the result of the close business and
technological cooperation between Motorola and so many distinguished
partners," said Chris Galvin, Motorola's president and chief operating
officer.

The Envoy communicator is a practical, all-in-one tool for people who
need to stay in touch.  Designed for both business and personal use,
it can communicate with popular public and private electronic mail
systems, Windows-based computers, Macintosh computers and fax
machines, as well as with other Envoy communicators.  It can keep
track of appointments, expenses, addresses, telephone numbers,
telephone calls, billing preferences and time zones.

"Motorola's leadership and expertise in wireless communications, the
powerful Magic Cap and Telescript environment, and the outstanding
applications from so many software developers and communication
service providers make it possible to bring end-to-end solutions to
market, allowing users to communicate and access information
anywhere," said Bob Growney, president and general manager of
Motorola's Messaging, Information and Media Sector.

A user can write on the Envoy communicator with the accompanying
stylus, or even use a finger, to type and select or move objects on
its screen.  Envoy communicator owners can use an on-screen keyboard
to input information, use electronic ink to draw or write personal
notations, or send messages and faxes in their own handwriting.  A
Single Tool, Three Ways to Communicate

Using the Envoy communicator, people can send and receive messages and
information any time, anywhere, and at their convenience.  A two-way
wireless packet data modem from Motorola is built into every Envoy
communicator, allowing users to stay in touch wirelessly when access
to a phone line isn't convenient.  Envoy communicator owners can also
access standard telephone lines to communicate, using the built-in fax
modem.  And through the built-in infrared communications link, users
can instantly exchange data -- such as business card information --
between Envoy communicators.

The two wireless communication services offered to Envoy communicator
users, AT&T PersonaLink(SM) Service and RadioMail(TM), will be
connected via the ARDIS(R) nationwide wireless data communications
network, which serves more than 400 metropolitan areas in the United
States.

Communication and Productivity Software built in Motorola's Envoy
personal wireless communicator features a full complement of
integrated electronic mail and information services.  Through
RadioMail, Envoy communicator owners can wirelessly communicate with a
broad population of electronic mail users via the Internet, and
commercial and public mail systems.  America Online(R), which is also
built into the Envoy communicator, allows users to receive stock
quotes and also communicate with electronic mail users. Using
Telescript technology, AT&T PersonaLink Services will let Envoy
communicator users take advantage of personal intelligent assistants.
These intelligent assistants will make it easy for PersonaLink
Services subscribers to send smart electronic messages, seek out
information, and shop for products and services, using both wireless
and wireline means.  The built-in Official Airline Guides (OAG(R))
Flightline(TM) service gives air travelers direct access to timely
flight information.

The Envoy communicator also comes with PenWare's PenCell(TM)
spreadsheet, a software program that's compatible with Lotus 1-2-3 and
Excel file formats, and provides powerful spreadsheet and graphing
capabilities to Envoy communicator users.  Additionally, Motorola and
Intuit have entered into a letter of intent to build into the Envoy
communicator Pocket Quicken SmartWallet(TM), an application that lets
users capture and sort expenses in real time.

For maximum flexibility, the Envoy communicator features two PCMCIA
(Personal Computer Memory Card International Association) type II
slots, allowing Envoy communicator owners to simultaneously run
third-party software applications and add memory to store more
information.

To augment the functionality of the Envoy communicator, Motorola has
made it convenient for customers to purchase additional products and
services through the Motorola Software and Accessories Catalog,
packaged with each communicator.  Motorola is working with multiple
independent software developers who have created a variety of
applications and services for the Envoy communicator; more than 15
applications, ranging from travel maps to daily news summaries, will
be available when the product ships.

Motorola's expertise in wireless technologies and semiconductors has
made it possible to miniaturize sophisticated circuitry, and fit it in
one small, portable package.  The Envoy communicator weighs 1.7 lbs. and
measures 7.5 inches in width, 5.7 inches in height, and 1.2 inches in
depth.

Motorola's Envoy communicator will be available in the United States
this summer through multiple distribution channels.

The Envoy communicator is expandable, therefore future wireless
connectivity may be possible with other networks, such as Cellular
Digital Packet Data (CDPD), Mtel's Nationwide Wireless Network (NWN),
the Motorola Integrated Radio System (MIRS) service providers and RAM
Mobile Data.

The Wireless Data Group is part of Motorola's Messaging, Information
and Media Sector, and incorporates the company's business activities
involved in the design, manufacture and distribution of wireless data
communications products, infrastructure equipment and systems for
worldwide markets.  Motorola, headquartered in Schaumburg, Illinois,
is one of the world's leading providers of wireless communications,
semiconductors, and advanced electronic systems and services.  Sales
in 1993 were $17 billion.

Subject: AT&T Cellular Phone 3050 and Extended Range Cordless Phone 9530


Here are two short descriptions of two AT&T telephones that I have not seen
described in the Digest.  These descriptions are copied from the 1993 AT&T
Annual Report.

Mobile Cellular Telephone 3050
A cellular phone with a built-in digital, tapeless answering system and
voice-activated operation.  $399.99 at AT&T Phone Centers and at selected
retailers.  For more information, call [phone].

Extended Range Cordless Telephone 9530
A cordless phone with a range about for times the distance of traditional
cordless phones.  Virtually interference-free privacy and crisp, clear sound
on 173 channels.  $449.99 at AT&T Phone Centers and at selected retailers.
For more information, call [phone].

It is not clear to me whether the cordless phone is spread spectrum.
The prices are certainly high.  By the way, AT&T plans is asking
stockholders to approve changing the name of the Company from American
Telephone and Telegraph to AT&T.

Organization: Dell Computer Corporation


I am a programmer in the Telecom Department here at Dell, and my
latest project is to pull trunk usage data and produce usage
predictions for said trunks.

This isn't really my field, so I had a co-worker write the request for
me:

  We need a way to calculate the number of voice circuits needed to
  provide standard levels of service using the Retrial method.  Ideally
  we would plug into a formula the following:

     - offered CCS of traffic
     - grade-of-service desired (P.01, P.001, P.05)

  The formula would then calculate the number of trunks needed WITHOUT
  resorting to lookup tables.

  If available, formulas for Erlang B method would also be useful.

These would be most useful as assembler, C, or XBase sub-routines.
Does any one know where I can find these?

Hi,

A while ago there was a post in this newsgroup about "managerium", the
latest scientific element discovered. Very funny indeed, and when I
showed it to one of my colleagues he remembered seeing a more
elaborate version of this where also the "morons" were described. Does
anybody know where I can find a copy of this?

Thanks a lot in advance,

Thursday, March 10, is the 118th anniversary of the first telephone

The building in Boston where Bell and Watson did their work has long
since been torn down to build a government office, but the site is
marked by a small granite shaft and a pair of payphones.

[TELECOM Digest Editor's Note: Things have come a long way in the past
century haven't they ... we used to have a very nice telephone museum
here in Chicago at the IBT headquarters on Randolph Street but one day
the company just decided to close it down and put the 'Work at Home
Center' there instead. The museum is missed. Anyway, happy 118th to
Mother and her children!    PAT]
