MONITOR TYPE COMMENTS
LINE
CV-L 16383 Line Code Violation, count of BIP errors detected at the Section layer using the B2
byte in the incoming SONET signal
CV-LFE 16383 Far-end Line Code Violation, a count of BIP errors detected at the far end LTE and
reported back to the near end LTE using the Remote Error Indicator (REI) in the
Line overhead
ES-L 900 Line Errored Seconds, number of seconds in which at least one Line layer BIP, or an
AIS condition was detected
ES-LFE 900 Far-end Line Errored Seconds, count of the seconds in which at least one Line BIP
was detected by the far end LTE or an RDI-L defect was present
SES-L 900 Line Severely Errored Seconds, a count of seconds in which a set number of Line
layer BIP errors, or an AIS condition were detected
SES-LFE 900 Far-end Line Severely Errored Seconds, a count of seconds in which a set number of
Line layer BIP errors, or AIS were detected by the far end LTE
UAS-L 900 Line Unavailable Seconds, a count of seconds in which the Line was considered
unavailable
UAS-LFE 900 Far-end Line Unavailable Seconds, a count of seconds in which the Line was
considered unavailable, reported by the far end LTE to the near end LTE using the
RDI in the Line overhead
PATH
CV-P 16383 Code Violation, a count of BIP errors detected at the Path layer using the B3 byte of

reported back to the near end LTE using the Remote Error Indicator (REI) in the
Path overhead
ES-P 900 Path Errored Seconds, number of seconds in which at least one Path layer BIP,
Alarm Indication Signal (AIS), or Loss Of Pointer (LOP) condition was detected

BIP errors, AIS, or LOP were detected
SES-PFE 900 Far-end Path Severely Errored Seconds, a count of seconds in which a set number of
Path layer BIP errors, AIS, or LOP were detected by the far end LTE and reported
back to the near end LTE using the RDI-P bit in the Path overhead
UAS-P 900 Line Unavailable Seconds, a count of seconds in which the Line was considered
unavailable
UAS-PFE 900 Far-end Path Unavailable Seconds, a count of seconds in which the Path was
considered unavailable, reported by the far end LTE to the near end LTE using the
RDI in the Path overhead
