We did not order touch tone service here in Reston, VA, which is also
C&P, and tones are not recognized.  This only presents a few minor
problems:
	1. Have to switch from pulse to tone when talking to
	   customer devices that respond to tones at the called party.
	2. Takes a long time to dial a number.  Those make/break pulses
	   occur at ten hertz, and that isn't even taking interdigit
	   intervals into account.
And where did we learn these terms such as "make/break ratio" and 
"pulse rate" ?  From "Understanding Telephone Electronics" the
$3.49 tutorial on the phone written by Texas Instruments Training,
and available at Radio Shack.

Just in case anyone is interested, we here at Citcom Systems are 
working on a man-machine interface for a dx3-3 cross connect system.

We don't know who can provide the service to West Germany you require.
We do use normal 1200 baud modems to call our main office in Paris,
France on a daily basis, however.  Takes a long time for the switching
to take place, and the line is often noisy.  Line noise is no problem,
of course, as we use the retransmitting uucp protocols.
