12.4 Performance-Monitoring Parameter Definitions
FC-L Line Failure Count (FC-L) is a count of the number of near-end line failure events. A
failure event begins when an AIS-L failure is declared or when a lower-layer,
traffic-related, near-end failure is declared. This failure event ends when the failure
is cleared. A failure event that begins in one period and ends in another period is
counted only in the period where it begins.
FC-LFE Far-End Line Failure Count (FC-LFE) is a count of the number of far-end line failure
events. A failure event begins when Line RFI-L failure is declared, and it ends when
the RFI-L failure clears. A failure event that begins in one period and ends in another
period is counted only in the period where it began.
FC-P Near-End STS Path Failure Counts (FC-P) is a count of the number of near-end STS
path failure events. A failure event begins when an AIS-P failure, an LOP-P failure,
a UNEQ-P failure, or a TIM-P failure is declared. A failure event also begins if the
STS PTE that is monitoring the path supports ERDI-P for that path. The failure event
ends when these failures are cleared.
FC-PFE Far-End STS Path Failure Counts (FC-PFE) is a count of the number of near-end STS
path failure events. A failure event begins when an AIS-P failure, an LOP-P failure,
a UNEQ-P failure, or a TIM-P failure is declared. A failure event also begins if the
STS PTE that is monitoring the path supports ERDI-P for that path. The failure event
ends when these failures are cleared.
LBC Laser Bias Current (LBC) is represented by the percentage of the normal (100%)
laser bias current of the laser on the card port. The high laser bias current
(LBC-HIGH) threshold is the percentage of the normal laser bias current when a high
current TCA occurs. The low laser bias current (LBC-LOW) threshold is the
percentage of the normal laser bias current when a low current TCA occurs.
NPJC-PDET Negative Pointer Justification Count, STS Detected (NPJC-PDET).
NPJC-PDET-P Negative Pointer Justification Count, STS Path Detected (NPJC-Pdet-P) is a count of
the negative pointer justifications detected on a particular path in an incoming
SONET signal.
NPJC-PGEN-P Negative Pointer Justification Count, STS Path Generated (NPJC-Pgen-P) is a count
of the negative pointer justifications generated for a particular path to reconcile the
frequency of the SPE with the local clock.
OPT Optical Power Transmitted (OPT) is represented by the percentage of the normal
(100%) optical transmit power of the laser on the card port. The high optical power
transmitted (OPT-HIGH) threshold is the percentage of the normal transmit optical
power when a high transmit power TCA occurs. The low optical power transmitted
(OPT-LOW) threshold is the percentage of the normal transmit optical power when
a low transmit power TCA occurs.
OPR Optical Power Received (OPR) is represented by the percentage of the normal optical
receive power of the card port. The high optical power received (OPR-HIGH)
threshold is the percentage of the calibrated receive optical power when a high
receive power TCA occurs. The low optical power received (OPR-LOW) threshold
is the percentage of the calibrated receive optical power when a low receive power
TCA occurs.
PPJC-PDET Pointer Justification STS Detected (PPJC-PDET).
