Subject: GSM Tariffs in Europe
Date: 25 Jul 1994 14:04:05 -0500
Organization: UTexas Mail-to-News Gateway


I had the opportunity to play around with a new GSM phone last
weekend, and was amazed by the features offered by this service, some
real, some still non-implemented (e.g. call forward). I travelled by
car from Milano, Italy, to Genova, and then West to the border with
France on the Italian riviera. I had almost everywhere good coverage
on the motorway and over the coast. Coverage appeared to be everywhere
on the road the same as for the other analogue (900 MHz, TACS)
cellular phone. To my surprise at the place of my stay some 15 km from
the French border, I realized that with the GSM phone I had the option
of using one of THREE (!) available networks (one Italian and two
French).  [US readers please do not laugh: phones in Europe are still
a monopoly in most countries :<( ]

As soon as I realized that I could make a call to France via one of
the the French telephone networks, thus bypassing the Italian
operator, I tried to find out more about the different rates, and rate
systems, used by the different GSM operators. Unfortunately, after
calling the Italian operator "SIP" on 119, they suggested that I
placed an Int'l paid call to each operator to get their tariffs (They
gladly provided me with their numbers in Paris, good only during
business hours Mon-Fri). This makes quite difficult and expensive to
get a clear picture, and e.g. select the best operator in countries
where more than one exists (e.g. France, Germany, UK, etc.).

If not supplied already, it would be helpful to the European GSM
owners if anyone could point out which are the current tariffs for
long distance and international calls when roaming in European
countries served by the GSM system, or at least provide the respective
GSM operators' toll free assitance number, which may be called when
entering a new network.  How could one decide which operator to use?
Maybe stopping at the first telephone boot when crossing the border
and have a look at the telephone directory? I would probably have to
stop at each operatr's telephone boot, which makes it most annoying
especially when you travel on motorways ;<) .

I will be glad to pass on any information on rates you may subject
when roaming thru the Italian SIP operator. Or you may call toll free
119 when you switch to the SIP network in Italy.

Any help will be gladly appreciated, and if there's enough interest I
will be glad to summarize. Please reply directly since I may not read
the news from here.

I also found most annoying to try calling Italy from France by
dialling 0039-XXXXX, and then today back at home I learned from my
telephone directory that in France you get access to the international
lines by dialing 19-39-XXXXXX; the situation is -- sadly -- all the
same non standard and most confusing when you dial e.g. from Austria:
00-40-XXXXX, Spain: 07-39-XXXXXX, the UK: 010-39-XXXXX, or Norway:
095-39-XXXXXXX). It's not a mistype, Austria disregards completely
Italy's country code by making it 40 instead of 39.

In new residential construction, what is the sensible and/or creative
way to run phone and data lines?  I'm thinking about pulling four pair
category 3 cable from a 66 or mini block in the basement to a box in
each room.  I'll use one pair to each room for primary house phone,
the others as needed for more phone lines or in-house LAN.  At the
block, I'll punch as necessary to get what I need.  I'll also pull
coax to the same location for cable TV.  Problems?  Suggestions?

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: Information on Telemarketing Lawsuits Wanted
Date: 25 Jul 1994 18:52:11 GMT
Organization: University of Michigan Engineering, Ann Arbor


Hello all,

I'm considering taking legal action against the company which provides
my residential long-distance phone service. Marketing representatives
from the company persist in calling me despite several requests to be
put on the do-not-call list. I know that the 1991 Telephone Consumer
Protection Act makes it illegal in certain circumstances to persist in
that manner. I have also heard of at least one successful action in a
Small Claims Court under this act -- that case involved telemarketing
on behalf of Citibank as I recall.

Does anyone know of other cases, preferably involving telephone
companies? The issue hinges on a "prior business relationship"
existing between the caller and the recipient. If the marketer opens
the call with a personal discussion on a topic specific to the
recipient, that might change the situation. So, "Hi, I'm calling to
confirm that we received your last month's payment of $47.23, and now
let me introduce our new plan ..." could supposedly be construed
merely as "good customer relations"!

Any leads on specific cases would be much appreciated. 


Thanks, 

John Murray, Universoty of Michigan

Today's newspaper included an insert from a retailer advertising a
trimline-style phone manufactured by Northwestern Bell.  While the ad
included the Bell System logo (now the RBOC logo), the name didn't
ring any bells with me.  I don't remember seeing the name on a list of
AT&T's former operating companies, but then I've been mistaken before.
Is this company out in Pac*Tel or US West territory?  Canada, maybe?

I have recently set up a complex voice mail system.  It basiclly is a
classified Ad system running on the Dialogic 4 port cards.  I
commissioned a company to write it using the VOS operating system as
supplied by PARITY software in the US.  It was very expensive to
develop.  However it has just come to my notice that I might have
saved myself a considerable amount of time and expense if I had used a
system called RING which is a GUI based development system.

I would like to "talk" to somebody who has experience with this
system.  I have seen the demo of RING but I would like to chat with
somebody who has used it to develop an application.

Also I am looking to source it directly from the company that makes it
can anybody give me a clue where the company is based?

Please e-mail me with any information you may have.

Thank you for taking the time to read this.
