Thanks for the offer, but I've got access to a whole bunch of different
V.120 equipment. The problem is that the packet tracing I've done doesn't
help me further, because I can identify some bits in the packets and I can
guess at others, but it doesn't conform to the layouts in the V.120 09/96
spec. Therefore, if someone has a professional ISDN analyzer that can
unpack those packets and tell me what the bits actually mean, I can start
doing some real work on V.120. For now, the entire science consists of
waving chickens.
I can connect to a V.120 system waving chickens and even get some data
across, but it is not reliable and besides, I don't want to tackle the
problem like this because without authoritative information on what
happens in this connection, I might very well blow the access system at
the other end out of the water by depleting resources or whatever.
