LOSS-L Line Loss of Signal (LOSS-L) is a count of one-second intervals
containing one or more LOS defects.
NIOS Non-Idle Ordered Sets (NIOS) is a count of received packets containing
non-idle ordered sets.
NPJC-PDET Negative Pointer Justification Count, STS Detected (NPJC-PDET),
formerly Pointer Justification Negative (PJNEG)
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.
OPR Optical Power Received (OPR) is the measure of average optical power
received as a percentage of the nominal OPR.
OPR-AVG Average Receive Optical Power (dBm)
OPR-MAX Maximum Receive Optical Power (dBm)
OPR-MIN Minimum Receive Optical Power (dBm)
OPT Optical Power Transmitted (OPT) is the measure of average optical power
transmitted as a percentage of the nominal OPT.
OPT-AVG Average Transmit Optical Power (dBm)
OPT-MAX Maximum Transmit Optical Power (dBm)
OPT-MIN Minimum Transmit Optical Power (dBm)
OPWR-AVG Optical Power - Average (OPWR-AVG) is the measure of average optical
power on the unidirectional port.
OPWR-MAX Optical Power - Maximum (OPWR-MAX) is the measure of maximum
value of optical power on the unidirectional port.
OPWR-MIN Optical Power - Minimum (OPWR-MIN) is the measure of minimum
value of optical power on the unidirectional port.
PJCDIFF-P Pointer Justification Count Difference, STS Path (PJCDIFF-P) is the
absolute value of the difference between the total number of detected
pointer justification counts and the total number of generated pointer
justification counts. That is, PJCDiff-P is equal to (PPJC-PGEN-P –
NPJC-PGEN-P) – (PPJC-PDET-P – NPJC-PDET-P).
PPJC-PDET Pointer Justification STS Detected (PPJC-PDET), formerly Pointer
Justification Positive (PJPOS).
PPJC-PDET-P Positive Pointer Justification Count, STS Path Detected (PPJC-PDET-P)
is a count of the positive pointer justifications detected on a particular path
in an incoming SONET signal.
PPJC-PGEN-P Positive Pointer Justification Count, STS Path Generated (PPJC-PGEN-P)
is a count of the positive pointer justifications generated for a particular
path to reconcile the frequency of the SPE with the local clock.
