Your likely not receiving all the control signals you need from your DSU/CSU. Check your cables for good connection and bent pins. I had a tranatlantic link fail once because a 3rd party engineer replaced a DSU/CSU. Rough with the cable to the router he bent a single pin, took the link out.

Yea,Turgon is right,check you cables because the serial interface is the physical(cable) connection

Certainly not a mourned one. If I never have to discuss crap like line encoding with a provider ever again, I'll be a happy camper.
