Probable Cause
A system timing reference
is detected.
Probable Cause
Incoming path • The provisioning of the near-end expected path trace does
trace label does not agree with the provisioning of the far-end path trace.
not match Correct the provisioning that is in error. Do not change
expected path expected trace based only on the basis of the incoming trace
trace label. value. This would defeat the purpose of this feature.
• If the path trace value provisioned at the far end is identical
to the provisioned expected trace at the near end, a
mismatch indicates a cross-connect error somewhere in the
path.
• If a cross-connect error is suspected in a ring configuration,
manually switch the channel to the other direction. If the
TRCM clears, check the cross-connects in the suspect
direction.
