passed.

– The unit has disabled the 

interface or frame relay link 
due to internal operating 
conventions.

virtual circuit is not warranted; 
that is, no alarm condition on 
the primary destination link 
has been detected.

is essentially disabled as a result 
of how the unit was configured.

both ends of the PVC is/are
