			Performance Monitoring Parameter Definitions
	Table 11-2	Performance Monitoring Parameters (continued)
	Parameter		Definition
	Rx ES-P		Receive Path Errored Second (ES-P) is a one-second period with one or
			more errored blocks or at least one defect.
	Rx ESR-P		Receive Path Errored Second Ratio (ESR-P) is the ratio of errored seconds
			to total seconds in available time during a fixed measurement interval.
	Rx SES-P		Receive Path Severely Errored Seconds (SES-P) is a one-second period
			containing 30 percent or more errored blocks or at least one defect; SES is
			a subset of ES.
	Rx SESR-P		Receive Path Severely Errored Second Ratio (SESR-P) is the ratio of SES
			to total seconds in available time during a fixed measurement interval.
	Rx UAS-P		Receive Path Unavailable Seconds (UAS-P) is a count of one-second
			intervals when the E-1 path is unavailable on the signal receive end. The
			E-1 path is unavailable when ten consecutive SESs occur. The ten SESs are
			included in unavailable time. After the E-1 path becomes unavailable, it
			becomes available when ten consecutive seconds occur with no SESs. The
			ten seconds with no SESs are excluded from unavailable time.
	Rx BBER-P		Receive Path Background Block Error Ratio (BBER-P) is the ratio of BBE
			to total blocks in available time during a fixed measurement interval. The
			count of total blocks excludes all blocks during SESs.
	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.
	MS-SES		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.
