That was the first thing I tried:  first trying to unload/reload the 
wct1xxp and
zaptel modules, then reload them, then tried rebooting the computer (multiple
times), then this morning, I gave it a 30 minute time out.  No effect - still
getting the D-chan errors.

Unfortunately, the system is some 90 miles north of here so I can't verify if
anything on the Adtran has changed or not (or reseat cables).  My remote hands
aren't available right now either so I can't verify anything regarding the
circuit at this time.

The fact that I am not getting any error reports at all about the transport
(HDLC type errors) tends to make me think that the circuit is fine.  I would
have to imagine that if the channel switched from PRI to T1 it would throw all
kinds of errors.  Same thing if the signaling or buildout or what not was
incorrect.

The only errors I am seeing are the ones about the D channel not being there,
and one (probably quite related) about "head of queue has not been transmitted
yet".
