I've got a Teles.PBX. That's a PC-Based beast with 4-Port ISDN Boards 
and optionally analog boards. As that Company, or better that division 
of that company, now does no more exist since about 5+ years, there's no 
more software updates for it.

That's not that easy. The main thing would be to see if the ISDN card 
I'm using (AVM Fritz) is not confused about a NT1- S-Bus without power 
on it. That's normal for P2P-(DDI)-BRI's over here. From what I've read, 
the driver should be able to handle that through configuration made with 
isdnconfig at system startup. I can't test that now, but I'll see if I 
can disconnect the PBX for some time on the Weekend.
