Performance Monitoring Parameter Definitions

Table 11-2	Performance Monitoring Parameters (continued)
Parameter		Definition
HP-EB		High-Order Path Errored Block (HP-EB) indicates that one or more bits are
		in error within a block.
HP-ES		High-Order Path Errored Second (HP-ES) is a one-second period with one
		or more errored blocks or at least one defect.
HP-ESR		High-Order Path Errored Second Ratio (HP-ESR) is the ratio of errored
		seconds to total seconds in available time during a fixed measurement
		interval.
HP-NPJC-Pdet		High-Order, Negative Pointer Justification Count, Path Detected
		(HP-NPJC-Pdet) is a count of the negative pointer justifications detected
		on a particular path on an incoming SDH signal.
HP-NPJC-Pdet		High-Order Path Negative Pointer Justification Count, Path Detected
		(HP-NPJC-Pdet) is a count of the negative pointer justifications detected
		on a particular path on an incoming SDH signal.
HP-NPJC-Pgen		High-Order, Negative Pointer Justification Count, Path Generated
		(HP-NPJC-Pgen) is a count of the negative pointer justifications generated
		for a particular path.
HP-PJCDiff		High-Order Path Pointer Justification Count Difference (HP-PJCDiff) 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, HP-PJCDiff is equal to
		(HP-PPJC-PGen – HP-NPJC-PGen) – (HP-PPJC-PDet – HP-NPJC-PDet).
HP-PJCS-Pdet		High-Order Path Pointer Justification Count Seconds (HP-PJCS-PDet) is a
		count of the one-second intervals containing one or more HP-PPJC-PDet
		or HP-NPJC-PDet.
HP-PJCS-Pgen		High-Order Path Pointer Justification Count Seconds (HP-PJCS-PGen) is
		a count of the one-second intervals containing one or more HP-PPJC-PGen
		or HP-NPJC-PGen.
HP-PPJC-Pdet		High-Order, Positive Pointer Justification Count, Path Detected
		(HP-PPJC-Pdet) is a count of the positive pointer justifications detected on
		a particular path on an incoming SDH signal.
HP-PPJC-Pgen		High-Order, Positive Pointer Justification Count, Path Generated
		(HP-PPJC-Pgen) is a count of the positive pointer justifications generated
		for a particular path.
HP-SES		High-Order Path Severely Errored Seconds (HP-SES) is a one-second
		period containing 30 percent or more errored blocks or at least one defect.
		SES is a subset of ES.
HP-SESR		High-Order Path Severely Errored Second Ratio (HP-SESR) is the ratio of
		SES to total seconds in available time during a fixed measurement interval.
HP-UAS		High-Order Path Unavailable Seconds (HP-UAS) is a count of the seconds
		when the VC path was unavailable. A high-order path becomes unavailable
		when ten consecutive seconds occur that qualify as HP-SESs, and it
		continues to be unavailable until ten consecutive seconds occur that do not
		qualify as HP-SESs.
