[comp.dcom.telecom] European vs. US telephone systems query: Responses

cdaf@IUVAX.CS.INDIANA.EDU (Charles Daffinger) (04/03/88)

Here are the replies I received to my recent query about the compatibility
of US telephone equipment (eg, answering machines) with the West German
telephone system.  As some people have requested to remain anonymous, 
I've simply removed the headers and signatures of all articles... 

Thanks to all who responded.

It is illegal to hook your own equipment to the phone-system and the BP
(BundesPost), the government postal authorities, who also governs the
phone-system, is very severe with anyone they catch meddling with their
prime profit-center.

BTW, there are no modular plugs, so if your friend decides to go ahead
anyway, he better take along some parts ... yes, it would work.

Charles,

I live in Germany, so probably can best answer your question.  No compatibility
problem,  BUT  there  are big time legal problems.  See, the Deutsch Bundespost
(that's Germany's Ma Bell) will only allow "approved" answering machines to  be
hooked  up.   The ones that are approved are pretty outrageously expensive (all
over $200-$300).  Also, you must pay the Bundespost to hook  up  your  machine.
Then  you have to pay a monthly fee to have the priviledge to have the manchine
in the first place.  After being used to the US system, it's pretty ridiculous.
Now, I know several people here who have just hooked their American machines up
and away you go....but you run the risk of fines and loss of  service  if  they
catch  you.

In article <7029@iuvax.cs.indiana.edu> you write:
>A friend of mine would like to purchase an answering machine in the 
>united states, to be used on the telephone system in West Germany.

The German post office, which runs the phone system there, has traditionally
been extremely paranoid about attaching anything not provided by them to the
phone system.  (It used to be illegal to use an acoustic coupler, even though
there was no electrical connection at all.)  Also, unlike most other telephone
authorities, they actually prosecute people who make illegal attachments.

I'd be extremely wary about attaching some U.S. answering machine to a
German phone line -- he could end up in court.  If he insists, you can tell
him that technically most phone systems in the world use the same electrical
interface to the phone (largely the same as that used by Bell in the late
1800's) and assuming he can deal with 110 vs. 220 volts, 50 vs. 60 HZ, and
the different shaped power and phone plugs, any U.S. answering machine
should work.  Perhaps he should move to France where they sell phones and
answering machines in discount stores, just like here.

I am not sure about West Germany but I have successfully used
US equipment in all the Scandinavian countries and to the best
of my knowledge telephony is about the best standardized area
of telecommunications (thanks to CCITT, which really was the
first serious standardization organisation in the world).

It is possible that US equipment is not type approved in Germany
and should not be connected to the network (that is you are
operating at your own risk) but who cares :-)
Nevertheless, I am >90% sure it works without problems (save the
different voltage, of course).

So, go for it!
