Do you have access to both ends of the circuit?  No errors on either 
end?  In which direction does the provider tech show errors and where in 
the circuit is the test set being placed?  Does the test set show errors 
running to a hard (co-ax) loop?  if so you have a problem with the span.

Have you verified that there is exactly one clocking source on the circuit?

We have several.  In some cases a 10dB attenuator is needed on the 
receive side if the carrier is too "hot" but this manifests as errors.
