jjfai@alertnet.com recently inquired about GSM support in the U.S.

   Recently McCaw's New York operation, Cellular One began an
International Roaming service involving GSM phones.  One TD responder
to the original post pointed out that there are NO cellular carriers
supporting GSM on their U.S. systems.  This is absolutely correct.
However, if you choose local service with Cellular One in New York,
you can retain your GSM unit and can have your GSM calls (if you roam
back in Europe) billed back to a single account -- your Cellular One
account.

If you have questions about this service you can talk to cathy.oshea@

Subject: Last Laugh! IBM Buys Episcopal Church


For Immediate Release

 The Chairman of IBM announced today that, in response to Microsoft
Corp.'s acquisition of the Roman Catholic Church, IBM has bid for and
acquired the Protestant Episcopal Church in the United States of
America for $1 billion.

 "We are the oldest and most prestigious computer company in the
world," he said, "and we cannot be seen to be lagging behind in the
race for preeminence in the religious software and hardware markets.
We have tendered an offer to the Most. Rev. Edmund Browning, Presiding
Bishop of the Episcopal Church and Pamela Chinnis, President of the
House of Deputies of General Convention, and they have recommended
acceptance to the shareholders / communicants."

 The Episcopal Church is one of the oldest and most respected
denominations in the United States.  Many current and former
officeholders, including many Presidents, have been communicants.
Although its membership was declining in recent years, the latest
figures show a slight increase in membership.  A combination with IBM
will probably be beneficial in terms of putting "fannies in the seats"
in Episcopal Churches across the United States.

 There will also be great benefits to IBM in terms of international
connections through the Episcopal Church.  The Church is one of the
most senior members of the international Anglican communion by way of
its separation from the Church of England after the Revolutionary War
and the consecration in 1784 of its first Bishop, Samuel Seabury.  IBM
hopes to gain a foothold in the international religious business
through these connections, and perhaps tender a bid for the entire
Anglican Communion by the time of the next meeting of the world
Anglican bishops in London in 1998 (Lambeth Conference).  The
Archbishop of Canterbury, The Most Reverend George Carey, could not be
reached for comment.

 IBM and Episcopal Church are "good fit"

 IBM has had the distinction of being the first and, up until several
years ago, the most successful computer company in the world.  It was
founded by Herman Hollerith, the inventor of the computer card, in the
late 1800, and concentrated on business machines such as adding
machines and typewriters until the invention of the computer in the
1940. They invested heavily in this new technology, and became rich
from selling and maintaining them in the 1950's through 1980's.

 However, IBM's stodgy corporate culture prevented it from taking
advantage of newer technology.  It almost entirely missed the value of
personal computer technology in the late 1970's, allowing other
companies to use processes it developed to make so-called "clone"
personal computers.  It therefore lost out on the billions of dollars
spent on this technology over the past 15 years.

 IBM has recently spun off its typewriter and printer businesses and
concentrated on PC building and software, and has even resorted to
layoffs for the first time in its history.  The slogan, "No one was
ever fired for buying IBM" has become a bitter joke in the business
world.

 The Episcopal Church was, for a long time, considered the most
successful of the Protestant Churches in terms of wealth and power.
Many of the rich and famous swelled its numbers, and its liturgy was
noted for its archaic beauty as much as its treasury was noted for its
gilt-edged bonds.

 However, in recent years, with the dying-off of the elderly rich and
the fall in the birth rate among the bluebloods who remained, the
Episcopal Church has suffered both a decline in numbers and in
influence and wealth.  Notwithstanding the slogan, "The Episcopal
Church Welcomes You," numbers have only recently begun to increase
again as the Church begins to be seen as a place where outcasts can
take part in its life.

 Along with IBM, the Episcopal Church has had to resort to layoffs to
balance its budget, and the merger will allow both organizations to
trim even further their personnel costs.  IBM's chairman said today,
"We have been known as the place where the white-coated mystics take
charge of computers in sealed rooms.  As a direct result of this
merger, our white-coated mystic roster will be cut by half and merged
with the ordained ministry of the Episcopal Church.  After all, they
also wear white garments when celebrating their mysteries.  The
similarities outweigh the differences, and we think that we can bring
their white-suited mystics up to speed in JCL and C++ within a few
months."

 The Presiding Bishop and Ms. Chinnis issued a joint statement saying:
"We welcome this merger as a meshing of two great but sometimes
old-fashioned institutions. The merger will allow us to cut our
technical staff by half again, and concentrate our resources on
becoming the largest and most successful Protestant Church in the
United States. Our first IBM mainframe is already being installed in
the basement of 815 Second Avenue, the Episcopal Church Center in New
York."

 They continued: "So that we can assure ourselves that the Apostolic
Succession will be continued, the Bishops of the Episcopal Church will
lay hands on the Board of IBM in a ceremony at the Cathedral of St.
John the Divine in New York City.  Then, the entire House of Bishops
will travel up to Armonk, where they will be instructed in the use of
the personal computer."  The business writers of most US newspapers
will join the religion correspondents in recording this momentous
occasion.  Both the business and the religious communities are
awaiting the new developments that this historic merger will make
possible.

His Eminence Bill Gates, had no comment.

(Continued from last message)
numbers to as many as 37,000 members of the National Football League
Players, the American Institute for Foreign Study, and Cross Country
Healthcare.  AT&T also is selling the service to tens of thousands of
individuals who reserved numbers last summer, when the company
announced how people could use the new numbers.

     Customers can begin using the new personal number service, called
AT&T True Connections, in the next several weeks as local dialing
availability becomes universal.

     Anyone who needs to stay connected to business associates,
friends or relatives while moving from place to place can benefit from
having an AT&T 500 number.  People can tailor the service to their
needs for anytime-anywhere communications, and can keep their 500
numbers for life.

     The people signing up for AT&T's service include real- estate
agents, who move around a lot during the day; business owners and
executives who spend time in different offices during the week;
college students, who move between campuses and their homes; and
retirees, who travel throughout the year as both tourists and
grandparents.

     "AT&T 500-number service can save these people -- and the
important people in their lives -- time and money," said Joseph P.
Nacchio, president-AT&T Consumer Communications Services.  "They'll
spend less time exchanging numbers and tracking each other down when
they want to talk.  And they may even spend less money making fewer
calls."

     Customers can choose from several 500-number offers with a
variety of features available only from AT&T.  Each customer will have
a 500-prefix number that can be programmed to ring any telephone,
cellular phone, pager, fax machine or personal computer that can be
dialed directly in the United States and more than 200 other
countries.

     By dialing their own 500 numbers, customers can program several
phones to ring in sequence, retrieve voice-mail and fax messages and,
soon, make outgoing calls without calling cards or coins.

     Each of the AT&T 500-number packages will be available for an
introductory price of $1 a month, with no enrollment fee, through
April 30, 1995.  Voice-mail service will cost an additional $5.95 a
month.

     AT&T's 500-number service for businesses will include all
available features, and will cost $7 a month for each number after the
introductory offer has ended.  The company expects to add more
business-related features in the new year.

     A variety of packages for consumers allows each person to pick a
level of service that meets individual needs.  Beginning May 1,
subscriptions will range from $1 to $7 a month.

     Enrollment for business customers and consumers beginning May 1
will cost $10 for each randomly selected 500 number or $25 for each
specifically requested 500 number.

     In addition to monthly fees, a per-minute charge will apply to
calls made with 500 numbers.

     Calls within the United States, Puerto Rico and the U.S. Virgin
Islands during off-peak hours (from 5 p.m. to 8 a.m. weekdays, and all
weekend) will cost 15 cents a minute, whether the caller or receiver
pays.  Calls during peak hours (from 8 a.m. to 5 p.m. weekdays) will
cost 25 cents a minute.  Rates for some in-state calls may vary.
Calls made to or from other countries will be charged the regular AT&T
rates for those countries.

     Business customers can realize savings opportunities by applying
500-number charges to such volume-discount plans as Customnet and
Small Business Advantage Plus.

     Charges for consumers' AT&T True Connections calls can be
discounted through AT&T True USAsm Savings, and they also can earn
points in AT&T True Rewardssm and AT&T Global Rewardssm, the company's
customer-rewards programs.

     With voice-mail service, subscribers can receive messages and
gain more control over their communications.  For instance, it gives
them the ability to screen calls, and pager owners can receive
notification on their pagers when messages have been left in their
voice mailboxes.

     "We're offering a personal number service that gives customers
tremendous flexibility," Nacchio said.  "It's rich in features and
will help them better manage their communications."

     The pro football players, nurses and students getting 500 numbers
have distinct needs that AT&T meets.

   o The football players and others covered by the NFLPA
     agreement can program their 500 numbers to follow them to
     hotels around the country.

   o The foreign-exchange students' parents can call their
     kids' 500 numbers to reach them around the world.  The
     students also can automatically reverse charges on calls
     back to the United States from locations with touch-tone
     service.

   o The nurses and other medical specialists who take short-
     term jobs through Cross Country Healthcare, a national
     placement firm, can have their 500 numbers follow them to
     the apartments they rent.

     Both business customers and consumers can learn more about AT&T
True Connections by calling 1-800-TRUE-500, extension 439.  For
consumers to subscribe, they must have or obtain AT&T long-distance
service in their homes, but they are not required to enroll in any
specific program.

AT&T 500 PERSONAL NUMBER SERVICES

PACKAGES AND PRICES JANUARY 1995

     A single feature-rich package for business customers will be
available for the introductory price of $1 a month through April 1995.
These customers will receive all the features available to consumers,
plus business-related enhancements in coming months.

     Four packages for consumers offer a wide range of choices in
features, functions and prices.  All will cost $1 a month for an
introductory period through April 1995.

     The basic package, called "Private Line," offers a 500 number
that the subscriber can keep for life, no matter how many times he or
she moves within the United States.  AT&T currently can assign
subscribers 500 numbers that begin with 20 different exchanges, such
as 346, 367 and 677.  For example, a person's number could be
500-346-XXXX.  With this package, the calls to the 500 number go only
to the subscriber's home telephone.  It also allows subscribers to
make calls to their own homes when they're traveling.  Beginning in
February, they'll be able to charge calls to other places on their
AT&T True Connections accounts without coins or credit-cards.  This
package will continue to cost $1 a month after the introductory
period.

     The "Stay Close" package adds call-placing and the subscriber's
choice of call forwarding or reverse-billing to the basic package.
Call-forwarding lets the subscriber have 500-number calls forwarded to
virtually any other U.S. telephone number and to more than 200
countries and areas on demand.  Reverse-billing lets the subscriber
pay for calls from other people, when those people have a code number
given by the subscriber.  This package will cost $3 a month after the
introductory period.

     The "Traveler" package adds call-placing, call-forwarding and
reverse-billing to the basic package, and will cost $5 a month after
the introductory period.

     The premium package, "Navigator," offers all the above features
and adds call-sequencing, which lets a subscriber's 500-number calls
ring at several locations in sequence.  For instance, a call could be
forwarded first to an office phone, then a cellular phone, and then
home or even a hotel.  The subscriber could change the sequence as
often as desired.  This package will cost $7 a month after the
introductory period.

     For $5.95 a month, AT&T True Connections subscribers can add
voice-mail and receive an unlimited number of messages.  With
call-screening, they can choose to receive all calls, urgent calls,
calls from certain people, or send all calls to their voice mailboxes.
And pager owners can receive notification on their pagers when
messages have been left for them.

     Both business customers and consumers can learn more about AT&T
True Connections by calling 1-800-982-8480, extension 439.  For
consumers to subscribe, they must have or obtain AT&T long-distance
service in their homes, but they are not required to enroll in any
specific program.

The effect of a robbed bit is to introduce, 50% of the time, an
additional quantitization error that results in an overall reduction
of about 2db in the S/N ratio. This is not likely to be the limiting
factor in V.34 performance except possibly in situations where many D4
type links are involved in tandem. In the U.S., most intermachine
trunks are common channel direct connections so only the robbed bit at
each end of the IC/EC connection introduces the robbed bit (as well as
any non CCS systems in the EC). I believe that other types of noise
(other than quantization noise) will have a much greater effect on
V.34 peformance particular any type of impulse noise or cross-talk in
the analog portions of the local loop.

While I can't answer your question in scientific terms (aka %THD 
measurements, S/N ratios, etc.) I can answer it subjectively.

In Robbed Bit signalling, the "Robbed" bit occurs every sixth frame
(or sample if we are concentrating on an individual channel), thus in
every sixth sample the LSB is overridden with the value of the A bit,
then 6 samples later with the value of the B bit.

On a "quiet" idle channel (AB bits both 0), using u-Law PCM, the 
pattern sent 
over the channel would be: (in hex, LSB last)
   FF FF FF FF FF FE  FF FF FF FF FF FE ...

The difference in voltage of a standard CODEC (A/D converter for PCM)
from FF to FF is about 2 mV (on a scale from -8031 to +8031 mV).  So,
converted to an analog signal, the above waveform is a series of 2 mV
impulses occuring every 8000/6 = 1333.3 Hz.  This waveform is rich in
harmonics, so it "sounds" like a very high pitched, (although rather
quiet) whine, similar to the "ringing in your ears" sound.

Once the line is taken offhook (aka AB bits both become 1), then the
pattern becomes: 
   FF FF FF FF FF FF  FF FF FF FF FF FF ...

which is dead quiet.  (And since LSB=1, and AB=1 there is no 
distortion!)

Thus the noise associated with robbed bit signalling can be viewed as
superimposing the intended signal with the above impluse train.
Perhaps armed with this information, someone else can calculate the
noise/distortion measurments you are seeking.

Hope this helps!
