Definition
Loss of Frame Count (LOFC) is a count of the lost frames.
Non-Idle Ordered Sets (NIOS) is a count of received packets
containing non-idle ordered sets.
Optical Power Received (OPR) is the measure of average optical
power received as a percentage of the nominal OPR.
Average Receive Optical Power (OPR-AVG) is the average
received optical power measured in dBm.
Maximum Receive Optical Power (OPR-MAX) is the maximum
received optical power measured in dBm.
Minimum Receive Optical Power (OPR-MIN) is the minimum
received optical power measured in dBm.
Optical Power Transmitted (OPT) is the average optical power
transmitted as a percentage of the nominal OPT.
Average Transmit Optical Power (OPT-AVG) is the average
transmitted optical power measured in dBm.
Maximum Transmit Optical Power (OPT-MAX) is the maximum
transmitted optical power measured in dBm.
Minimum Transmit Optical Power (OPT-MIN) is the minimum
transmitted optical power measured in dBm.
Optical Power - Average (OPWR-AVG) is the measure of
average optical power on the unidirectional port.
Optical Power - Maximum (OPWR-MAX) is the measure of
maximum value of optical power on the unidirectional port.
Optical Power - Minimum (OPWR-MIN) is the measure of
minimum value of optical power on the unidirectional port.
Uncorrectable Words (UNC-WORDS) is the number of
uncorrectable words detected in the DWDM trunk line during
the PM time interval.
Valid Packets (VPC) is a count of received packets that contain
non-errored data code groups that have start and end delimiters.
