Re: ISDN PRI Won't come up

suspect bad hardware, then. Also, just to clarify:
on the change ds1 page -- Protocol Version: b
on the change signalling group page -- Supplementary Service Protocol: a

if you have that Supplementary Service Protocol as "b" you will not have working d-channel. If the ds1 protocol is wrong the d channel would come up but the b-channels wouldn't.

Try a different 120Ax and/or a different TN464x. Did you check the lights on the front of the TN464?
