[c-nsp] 7200 Line protocol bouncing

[Chuck Church]

Correct, usually full T1s are 'clear channel', so clocking is up to CPEs.
Fractional T1s will have clocking provided by the provider.

Not according to AT&T.  They say they provide a path, and clocking is up to
us - that's why one side uses internal, and the other is set to line.
That normally works fine, and has worked on these circuits until recently.

And again, I am seeing the same problems on the standalone T1s and the
T3 channels.  

Sincerely,
Michael Malitsky
