Subject: Wireless Communication Course
Organization: University of California, Berkeley


U.C. BERKELEY Continuing Education in Engineering Announces a short
course on Wireless Technology:

WIRELESS COMMUNICATION NETWORKS (July 26-27, 1994)

     There are technical bottlenecks to developing a ubiquitous
wireless multimedia environment: the capacity of the radio link, its
unreliability due to the adverse multipath propagation channel, and
severe interference from other channels.

     This course covers the principles and fundamental concepts
engineers need to tackle these limitations (e.g., a thorough treatment
of channel impairments such as fading and multipath dispersion and
their effect on link and network performance).  Topics include:
Introduction to Wireless Channels, Cellular Telephone Networks, Analog
and Digital Transmission and Wireless Data Networks.  Comprehensive
course notes will be provided.

Lecturer: JEAN-PAUL M.G. LINNARTZ, Ph.D., Assistant Professor of
Electrical Engineering and Computer Sciences, University of
California, Berkeley.  His work on traffic analysis in mobile radio
networks received the Veder Prize, an innovative research in
telecommunications award in the Netherlands.  At Berkeley he works on
communications for intelligent vehicle highway systems and multimedia
communications.  Professor Linnartz is the author of numerous
publications and the book "Narrow Land-Mobile Radio Networks" (Artech
House, 1993), the text for the course.

Hi,

We had a home grown telecommunication package that allowed us to send
alphanumeric messages to our PAC-TEL pagers. We are interested in
updating the softwaree. We are interested in reasonably priced
commercial software or in the protocol specs of the 800 number we
communicate with the old package.

Any help would be appreciated.

Subject: 1-800-OPERATOR Question/Problems
Date: 17 May 1994 07:55:50 -0400


I recently stayed in a hotel (Richmond, Va. Marriot) which had the
usual hotel phone surcharges. So, not wanting to burden myself with
huge add-ons to my hotel room, I decided to call collect.

Now, since I didn't know what extra costs would be added by the
hotel's contract with their service provider, I specifically used
'1-800-Operator' rather than "0" or "10288-0".

Well, I got the AT&T 'boing', the request for my name, and then got
the message 'enjoy your stay at the Marriot Hotel'.  Note again, that
this was a call placed through 1-800-opertor, NOT through a default '0'.

Alas, the call did not go through. Why? Because the person I was
calling was using his phone line and had call waiting. I heard the
ring, heard him click into my call and ask who was there. Yet the AT&T
switch somehow got this confused and, while the person I was calling
was still asking 'who's there', I got the synthesized voice saying
'your party appears to have hung up, please call again later'.

So this brings up two issues. First is the relationship with Marriot
and AT&T (remember, again, that this was a 1-800-operator call).
Second is the glitchy supervision when making calls to someone with
call-waiting.

Has anyone else had these problems? I eventually got through to my friend
by -paging- him and having him call me back ...


Take care,

We would like to offer TELECOM Digest readers a special price on
subscription to Telecomworldwire. The UK price is gbp700 per year for
fax. We would be pleased to offer **ALL** businesses a single-copy
price of the same (payable in Sterling or credit card) for delivery to
an electronic mail box connected to the Internet.  The companies would
have to sign a piece of paper (yes, old fashioned!) saying they would
not redistribute the material and basically subject the copyrighted
works in the same way as a printed publication. Site archive licences
are available. For genuine bona-fida non-commercial users a very
generous (in excess of 50 percent) discount would be offered upon
signing a similar warranty which also says that the information would
be for their sole use only and for non-commercial purposes).  Also we
have another product called Satnews, which I will forward similar
offer details on later next week.

Here are some sample stories from a recent issue:


-THAILAND EXPANDS INTERNATIONAL CALL ACCESS

TWW-12 May 1994-THAILAND EXPANDS INTERNATIONAL CALL ACCESS
TELECOMWORLDWIRE--(C) 1994 M2 COMMUNICATIONS LTD

BANGKOK, THAILAND- A plan by the Communications Authority of Thailand
to install a further 10,000 international telephone communications
circuits has been approved by the Thai Cabinet.  The Communications
Authority is to install 10,000 new circuits for international phone
calls, making up its fourth international transmission switching
centre.  Around Baht6,400 million will be spent on the project, based
at CAT's Bang Rak office.  The new circuits are set to be operational
by 1997, adding to the 7,000 existing international circuits in use by
CAT.  The Thai National Economic and Social Development board had
previously approved the plan, set to provide enough international
capacity until 2002, but plans are already being formulated to add a
further 25,000 international phone circuits between 1999 and 2017.

-AT&T WINS 'CONTROVERSIAL' SAUDI TELECOM CONTRACT

TWW-12 May 1994-AT&T WINS 'CONTROVERSIAL' SAUDI TELECOM CONTRACT
TELECOMWORLDWIRE--(C) 1994 M2 COMMUNICATIONS LTD

WASHINGTON, USA/RIYADHI, SAUDI ARABIA- AT&T Corp has won a six-year
US$4 billion contract to provide state-of-the-art digital switching
and fibre-optic networks to Saudi Arabia, and within hours of the news
being confirmed the contract was dogged with controversy. There are
allegations that President Clinton assisted AT&T in its contract win
to the detriment of competitors.  The massive contract will see around
1.5 million new fixed lines being installed as well as a cellular and
wireless data providing service for around 200,000 subscribers.
Ericsson said that it was surprised at the scope of the bid and the
way in which it had been handled, and Northern Telecom said that it
half expected the move as negotiations between AT&T and the Saudis
were advanced when AT&T ended its exclusive supplier agreement with
Bell Canada Ltd -- a NT offshoot -- earlier this year.  Intense
lobbying by Clinton and other US officials is said to have also helped
secure a US$6 billion contract in March for commercial aircraft from
the Saudis, awarded to Boeing and McDonnell Douglas. The Australian
Financial Review reported that Clinton had personally wrote to King
Fahd of Saudi Arabia, urging him to look favourably on the AT&T bid.
The New York Times added that Ronald Brown, Commerce Secretary made
two personal appeals during trips to Saudi Arabia since last September
and Secretary of State, Warren Christopher, spoke on AT&T's behalf
during his own trip there a month ago.

-BELLSOUTH IN BELGIUM MOBILE DATA PARTNERSHIP

TWW-12 May 1994-BELLSOUTH IN BELGIUM MOBILE DATA PARTNERSHIP
TELECOMWORLDWIRE--(C) 1994 M2 COMMUNICATIONS LTD

BRUSSELS, BELGIUM- As revealed in Telecomworldwire (TWW090594)
BelllSouth Corp's Mobile Data Inc business unit has joined forces with
France Telecom Mobiles International SA to jointly build and operate a
mobile data network in Belgium. This will be the first mobile data
network in the country. The new venture, known as RAM Mobile Data
Belgium, will spend around US$50 million on building the network, with
service scheduled to start in Brussels early next year. The network
will conform to the Mobitex mobile data standard, developed by
Ericsson and Swedish Telecom.

It's May, which means the new San Mateo County directories are out
from Pacif*c Bell.  Of course, I immediately turned to the area code
map page, where I saw little inset maps showing area codes 520, 360,
and 334, which will come into use during the life of the directory.
No mention yet of any other NNX area codes.

Zowie kapowie!

Can some knowledgeable soul throw light on the following questions:

- What protocol stack is specified by the SONET standard for
Operation, Administration, Maintainence & Provisioning? [I suspect the
answer is full blown CMIP, ACSE, ROSE as in Bellcore TR-303]

- What management platforms are currently in use at RBOCs in the US
that implement such standards? Are these proprietary platforms or
commercial implementations?

- In practice, do SONET equipment manufacturers implement the mgt
protocol specified for the OAM&P channel or is there some other
protocol is common use?  thanx for any help.

all U.S.  area codes -- listed in numerical order and with the
corresponding region?  Thanks for any tips.

We have a service from our local telco called Bulk Calling Line ID.
We have a dedicated line to the telco, attached to a Bell 202 modem.
At 1200 baud, we receive a line of ASCII text with the date, time
calling line, called line, and an indication of whether the called
line was busy or idle.

I believe there is just such a bulk interface available, called
something like SMDA (Service Message Desk Accounting?).  Anyway, I
think the deal is you order trunk connections, and one SMDA line for a
bunch of trunks.  Whenever a call comes in on one of your trunks, info
about the calling and called number (and maybe other stuff) is sent on
the SMDA line.  I think it is for answering services, voice mail
providers, and so forth.  But I imagine anyone could order it.
