KEY
NEND means "PM information collected directly from incoming T1 signals, both at local and remote sites." FEND means "ESF PRM information collected at the opposite ends of spans from the affected circuit and returned to the system via the ESF Datalink, both at local and remote sites". The framing format must be ESF in order for FEND information to be displayed.
Note: For Site 1, FEND information is at A; for Site 2, FEND information is at 2.
