Subject: GSM Phones in Europe
Late this year or early next year, when the networks are a bit more
complete, I'm planning to get a GSM phone for Europe, and I'm starting
to look at the alternative carriers, deals etc. Is there a FAQ/Info
file on GSM anywhere on the net or in a recent magazine?
I want to use the phone in France, UK and (probably) Benelux, without
excessive charges for incoming calls. Outgoing charges are not that
important, I could use a callback service if incoming calls are free.
Do any of the carriers in those countries allow international roaming
without charging (me) extra for incoming calls? Or do I always have
to
pick up the costs from my home country number to the overseas phone
location? Presumably it'll roam to me without the caller knowing?
Also, do any of the carriers have a voicemail service for when the
phone
is out of range or switched off? Can it be accessed whilst roaming
outside that country? Can calls be redirected to a terrestial phone
overseas? Or am I expecting too much?
As an alternative, is it possible to use multiple smart cards, so the
same phone thinks it is a French, British and Belgian phone, ideally
at the same time?
Finally, are there any GSM phones, available for use on all networks,
that handle data?

I am looking for sources of ISDN phones which can be used (possibly
certified) in Italy.
It seems to be quite hard to find ISDN phones here, an SIP does not
have a large choice of models (actually only two, and will take weeks
to have one after the order).
Thanks for any pointer. Please answer by email since I may not read

On August 11, 1994, the US District Court, for the Southern District
of Ohio, entered an Order and Opinion [17 pages], dismissing
CompuServe v. Patterson, Case No. C2-94-91, for want of personal
jurisdiction. A "scanned" copy of the order and opinion are available
on CompuServe's Legal Forum (LAWSIG) and America Online Legal Sig
(LEGALSIG), in the file named CIS3OH.ZIP.
CIS sued an individual Texas shareware author and long time service
subscriber in the Ohio District Court, attempting to convince the
court that all subscribers to CIS and shareware authors using its
online service to distribute shareware programs, send messages, or
upload other "content" consent to jurisdiction and venue in the
Columbus Ohio courts (where its central computer is located). The
court rejected this argument, although CIS reraised it on a Motion for
Rehearing filed Auguse 22, 1994.
This case is one of the first to reference the "information
superhighway,"
and provides a detailed discussion of the application of International
Shoe, the due process clause and the state long-arm statutes as they
relate to users of online services and brings them into the
"information
age." It should be of interest to users of any telecommunications
network and certainly to all Shareware authors.

Subject: Request For Comment - Government Electronic Documents
Organization: Australian Defence Force Academy, Canberra, Australia
Date: Tue, 30 Aug 1994 07:43:13 GMT
This is to request comments on the draft of:
"Implementing Effective Procedures for the Management of
Electronic
Documents in the Australian Public Service"
Available at URL:ftp://archie.au/ACS/implguid.html (about 111KBytes)
Send comments to: tomw@adfa.oz.au
The draft report, containing guidelines for implementing effective
procedures for the management of electronic documents, has been
produced by a subcommittee of the Commonwealth Government's
Information Exchange Steering Committee (IESC).
The IESC is an advisory body, responsible for providing guidance to
Commonwealth agencies on policies and strategic directions relating to
Information Technology and related issues, including
telecommunications.
For further details of the IESC contact Max McGregor (e-mail:
max.mcgregor@finance.ausgovfinance.telememo.au, ph: +61 6 263 3553,
fax: +61 6 263 2276).
The report is aimed at providing further assistance in putting those
management principles into practice. Although the report has been
produced primarily for the guidance of Commonwealth Agency records
managers, the basic principles can be equally applied throughout any
organisation that maintains electronic records.
Note that this is a working draft only. It is considered less than 20%
complete. However the committee would welcome your input to make it a
better document.

Hello,
I just started working with the network resarch group ad DMU in
Leicester .
My task is to give an overview on recent developments in the area of
digital cellular mobile radio (GSM, ...) and to identify possible
research projects. Currently I am working through a load of papers
from 1990 to 1992 on the subject.
But to get really up to date information I would be glad to get your
input:
- What happened in cellular digital communications in '93 and '94.
- Where do you see network related questions that would need further
investigation.
Thanks for you help; I will post a summary if I get some answers.
Cheers,

Subject: French Numbering System to Change
Date: Mon, 29 Aug 1994 20:27:29 BST
From: Clive D.W. Feather <clive@sco.COM>
According to a poster on uk.telecom, France is to switch from eight to
ten digit numbering in just under two years time:
I though the leaflet included with my France Telecom
phone bill on Saturday might be of interest.
It is headed '10 digit dialling', and goes on to explain that due
to
the exhaustion of number capacity due to faxes, mobile phones,
etc.,
France will go to 10-digit dialling as of "spring 1996".
The old Paris/province split will vanish, along with the need to
know
where the number you are calling is in order to know if you need
to use
the 16 or 16 1 prefixes. Instead Greater Paris numbers will all be
prefixed 01, and all other numbers will get a prefix 02, 03, 04
or 05, depending on which geographical quadrant of the country
they are in. All calls will now need to dial all 10 digits.
At the same time the international code will change from 19 to 00.
No mention of the 112 emergency number, nor of whether incoming
international calls drop the leading zero.

Subject: Security Deposit From Local Phone Carrier
Date: 30 Aug 1994 01:05:29 -0400
Organization: UMIACS, University of Maryland, College Park, MD 20742
Does anybody know any information about the regulation for
local phone company charging security deposits?
I am trying to get a phone connection for my new home. The local phone
company (Bell Atlantic) wants to charge me $50 deposit and $70 prepaid
for the first month's bill, plus other switch on fees. I think there
were a regulation on how the local company can charge deposits. I
remember I had a telephone five years ago and somehow I managed to get
rid of the deposit by telling them a regulation. It has been a long
time that I already forget the details. Could someone remind me of
that?
From the conversation I had with the operator, I know some people do
not have to paid deposits. But she won't tell me how to qulify that.
Also, another operator only want charge me the $50 and switch on fee.
So
I think they probably don't know what they were talking about, and
just want to charge whatever they can.
Please email to me.
Thanks,
DC
[TELECOM Digest Editor's Note: The telco is entitled to take
reasonable
actions to insure they are paid for their service. Unlike many
businesses,
telco is regulated under a rule which says they must provide service
on
demand to all qualified applicants without delay. In this context, a
qualified applicant is one who has demonstrated the ability and
willingness
to pay for the service. To demonstrate your 'ability and willingness'
to
pay, a security deposit and/or advance payment can be required. A
deposit
is an amount of money held in escrow for some period of time upon
which
telco is required to pay interest. It is forfeited in the event of a
default
in your payments. An advance payment on the other hand does not draw
any
interest and is immediatly applied as a credit on your account to
cover
the cost of the first month's service in advance and installation
fees.
Whether or not a security deposit and/or advance payment is required
cannot
be detirmined arbitrarily, nor can such requirements be made on the
basis of any illegal criteria such as the applicant's race, sex,
nationality
or living arrangements. Such a requirement can be made based on
telco's
own records of prior service to the applicant, or the records of other
telcos shared in common. It can be made on the basis of a report from
a
credit bureau. Some latitude is given to low-level employees in
detirmining
the amount or nature of any advance payment required; they are to
balance
customer goodwill with the best interests of the company. A security
deposit
equal to a month or two month's estimated billings is considered
reasonable
as is an advance payment equal to the estimated cost of installation
and
a month of service. There is no regulation or requirement that telco
give
its services away without some assurance of payment, although careful
and
courteous negotiation will often times reduce the amount demanded.
That,
plus of course a good credit history with telco itself. PAT]

I've just watched News at Ten and noticed the '...and finally'
story about the last phone box in the UK that still had the A+B
buttons. Those are the ones were you put a coin in, and if the
person answers you press A and the call is connected, or you
press B and get you money back if you get no reply.
It had been in service since the 1930s, and it was on Papa Stour
on the Shetland Islands. I say was, as today BT replaced with
with one of the latest digital pay phones.
The number is Papa Stour 224. I love those sort of phone numbers
don't you?

I mentioned recently that I've been using an Air Communicator combo
cellular phone and 14.4 modem (with a Mac Duo). I like it so far.
Several folks have asked for contact info, so I asked AC. They said:
1-800-AIR-DATA
or AIRSALES.MKT@AppleLink.Apple.COM
There's both Windows and (somewhat less) Mac support. The people there
have been helpful so far. The phone's quite a bit bigger than, say, a
Moto flip, but quite a bit handier than phone+adapter+modem. Also, the
modem works with a land line (the phone has an RJ11 jack).

Can you give some more details?
E&M is NOT the way to go. It is one of the oldest methods of doing
long distance (Like from the 1930's) and requires a minimum of 4 (but
more likely 8) wires from one switch to another. T1 at least gives 24
multiplexed lines on one twisted pair of wires.
Can you give more details as to what equipment you have and what your
voice mail system requires.

It sounds like you've covered most of the options; maybe painted
yourself into a corner, but here's a few ideas.
Although an XP set, have you looked at the fairly new Crouse-Hinds
model? I'm fairly sure the set has a line-powered amplifier, and big
buttons for use with gloves. It's also somewhat corrosion proof, if
that's an issue.
Is the area the phones are located conducive to small, sound-absorbent
kiosks? I've seen this used as an effective supplement to the
noise-cancelling handsets. I can locate a manufacturer or two if you
would like. Email as desired.
As a alternative to phones, how about non-audio signalling such as
something like DTMF keypads and displays on portable 2-way radios?
Heck, maybe Morse code -- you could glue a key on each hard hat. Even
head-mounted xenon flashers ...
Finally, although possibly a little out of scope, has your safety
group at all considered noise mitigation at the source? In the past I
have read that Dow {or is it Dupont?} consider noise mitagation in the
industrial setting as having exceptional safety benefits; on both
acute and chronic bases.

Depending on the decibel level of the noise in the room your
may want to investgate the "noise booths" That you find in industrial
telecom catalogs. These are fairly pricey though, but when I have
used them they are far superior to the various noise-cancelling
handsets. Another consideration is if it is a hazardous noise area
OSHA regulations may require you to provide a telephone that workers
can use without removing their hearing protection (plugs/muffs), or in
a location, such as the booth, where they can safely remove their
hearing protection while using the phone.
You can build a lower grade one of these things by making an
imitation phone booth out of plywood. Don't bother with a door for
it. and lining the inside with a layer of accustic foam. (those
"eggcrate" type foam mattress pads work fine) Hang the phone on the
outside of the booth, with a long enough handset cord to reach inside.
It is amazing how (relatively) quiet it is inside one of these things.
Materials cost about $100 at local stores, plus a couple hours and
some carpenters tools.
