15.4 Performance Monitoring Parameter Definitions
SASCP-P SEF/AIS Second (SASCP-P) is a count of one-second intervals containing
one or more near-end SEF/AIS defects.
SASP-P SEF/AIS Seconds Path (SASP-P) is a count of one-second intervals
containing one or more SEFs or one or more AIS defects on the path.
SES Severely Errored Seconds (SES) is a one-second period containing 30
percent or more errored blocks or at least one defect. SES is a subset of ES.
SESCP-P Severely Errored Seconds CP-bit Path (SESCP-P) is a count of seconds
containing more than 44 CP-bit parity errors, one or more SEF defects, or
one or more AIS defects.
SESCP-PFE Severely Errored Seconds CP-bit Path Far End (SESCP-PFE) is a count of
one-second intervals containing one or more 44 M-frames with the three
FEBE bits not all collectively set to 1, or with one or more far-end SEF/AIS
defects.
SES-L Severely Errored Seconds Line (SES-L) is a count of the seconds
containing more than a particular quantity of anomalies (BPV + EXZ >
44)
and/or defects on the line.
SES-P Severely Errored Seconds Path (SES-P) is a one-second period containing
at least one defect. SES-P is a subset of ES-P.
SES-PFE Far-End Path Severely Errored Seconds (SES-PFE) is a one-second period
containing at least one defect. SES-PFE is a subset of ES-PFE.
SES-PM Path Monitoring Severely Errored Seconds (SES-PM) indicates the
severely errored seconds recorded in the OTN path during the PM time
interval.
SESP-P Severely Errored Seconds Path (SESP-P) is a count of seconds containing
more than 44 P-bit parity violations, one or more SEF defects, or one or
more AIS defects.
SESR-P Path Severely Errored Second Ratio (SESR-P) is the ratio of SES to total
seconds in available time during a fixed measurement interval.
SESR-PM Path Monitoring Severely Errored Seconds Ratio (SESR-PM) indicates the
severely errored seconds ratio recorded in the OTN path during the PM
time interval.
SES-SM Section Monitoring Severely Errored Seconds (SES-SM) indicates the
severely errored seconds recorded in the OTN section during the PM time
interval.
Tx AISS-P Transmit Path Alarm Indication Signal (AISS-P) means that an alarm
indication signal occurred on the transmit end of the path. This parameter
is a count of seconds containing one or more AIS defects.
Tx BBE-P Transmit Path Background Block Error (BBE-P) is an errored block not
occurring as part of an SES.
Tx ES-P Transmit Path Errored Second (ES-P) is a one-second period with one or
more errored blocks or at least one defect.
Tx ESR-P Transmit Path Errored Second Ratio (ESR-P) is the ratio of errored seconds
to total seconds in available time during a fixed measurement interval.
