I have successfully connected other platforms in DCE mode via ppp over x.21 to my 2516's in DTE mode, but can't get the line protocol up when the 2516's are DCE-TERMINAL-TIMING-ENABLE, DCE-cabled (the link flaps). Debug s0 shows DCE cable disconnected msg, and ppp NACK'ing. IOS is 11.2. I have tried various clock rates etc to no avail. I am beginning to suspect LCP, but don't know how to get any further :-(

what about a sh config and a sh controllers
