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.
