That is the short answer -- but it is a very misleading one...
 
As you point out, the difference in carrier (900MHz vs 1.9GHz) and
other air interface is important.

However, the difference between MAP / IS41 only matters at the higher
protocol layers. To be simplisitic 'digits is digits' and so long as a
base station contains a Layer 2 protocol that can detect the type of
call and process it according to the right menu of algorithms, then
why is there a problem?
 
Detect which call it is, select the software, translate as required --
and BINGO !

Considering Alliant went Chapter 7 -- I don't think it qualified as

I wasn't there when it folded -- but since it's main competitor Convex
is still alive -- I wouldn't consider it well run or successful.

Alliant had some very nice engineering touches, some good design folks

Greetings,

I will soon be moving to southern Germany (Friedrichschafen) for a
couple of years and am interested in getting a GSM phone for use both
there and during my ocassional trips back to the UK.

I currently have an Nokia 101 analogue, which I think is a very well
designed and functional phone (for it's time) and thus am thinking
about getting the similarly styled Nokia 2110 GSM phone, which I
understand is pretty much the dog's bollocks as far as GSM phones go.

Could somebody please post or email me the costs of this and similar
phones in Germany, and also details on the different tariffs 
available, 
eg monthly line rental, call costs, insurance etc etc.

I am wanting to set up an occasional high speed data link from UK to
Iceland. My initial idea is to use 28.8kbps modems but I would really
like to use ISDN. British Telecom do not have an ISDN service to
Iceland nor do they claim to have any future plans. Does anyone know
if Iceland runs or plans to run ISDN?

Also, to which approvals standard must modems conform? I hear that it
is to Danish standards but I'm not sure.

Lastly, does anyone have a contact phone/fax no or email address for
the Iceland telephone company?

If anyone in Iceland is out there reading this please email me!

Subject: Disabling Call Waiting
Date: 21 Dec 1994 11:24:37 -0500
Organization: Clam Associates


Hi,

I have a hypothetical question.  If I have call waiting, I can prefix
my call with *70 to cancel call waiting for my phone for the duration
of the call.  If I want to call a friend who also has call waiting
using my modem so that his modem will pick up, is there some way to
disable call waiting for both parties so that the modems will not be
interrupted?


Thanks,

Jim


[TELECOM Digest Editor's Note: It all depends. Assuming you have the 
permission of the person (whose modem) you are calling to make such a
change, and assuming that person's phone line has both the ability to
disable call waiting and *disable it after a call has been received*
then yes, it can be done. Normally disabling call waiting has to be
done before a call is placed, in the process of dialing the number. In
some central offices, if the subscriber has three-way calling (thus
giving him a valid reason for flashing the hook once a call is in
progress) that hook flash can be used to dial a stand-alone *70 and
automatically return to the call in progress with call waiting 
disabled
for the duration of the call. 

The trouble comes up between modems. If his modem answers yours, then
any flash of the hook afterward is going to put you on hold, cause a
loss of carrier and the connection to be dropped, your modem making 
the
assumption there was no answer, or the call was finished or whatever.
So, he has got to do some funny business *before* his modem answers 
your
call. He cannot just have the modem answer, send carrier, flash and
leave the line momentarily. *If* (big if!) he can flash the hook in
the middle of a call to do *70, then what he has to do is when the
phone rings, take it off hook, pause about two seconds, flash the 
hook,
dial *70, get returned to the call in progress (yours) then tell the
modem ATA, that is, to go off hook in answer mode. Meanwhile, your 
modem
has been sitting there patiently waiting for an answer.  

Now what if he is not home, or you want to do all this automatically?
Well ... he is going to need to write a string for the modem which
tells it to indeed answer, but not send carrier right away; to answer
but pause a couple seconds, do a switchhook flash, dial *70, pause a
couple seconds, then do ATA. 

An alternative is if you can get your modem to stand by and not drop
carrier for an extended period of time. One of the S-registers can
probably be set to a very high value (like 255) which will cause your
modem to tolerate a very long loss of carrier for the few seconds he
is going to have you on hold. If that can be done, then he can answer
you normally and have his computer send you a little message saying
'please hold on' or something to that effect. His computer sends his
modem a string to get its attention *while not getting the attention
of your modem in the process*, flash, dial *70, do ATO or whatever to
return to the connection in progress.

Now and again people ask here how to make call waiting and modems
compatible. The simple answer is you cannot. Yes, there are various
ways to gerry-rig the whole thing with limited success. Better though,
that you both bite the bullet and go with the accepted rule of thumb
in data communications:  *a dedicated line for the modem*, with no
custom calling features on that line, except maybe Caller-ID if you
see a need for it, or perhaps speed dialing, etc.   PAT]
