Note

In CTC, the count fields for HP-PPJC and HP-NPJC PM parameters appear white and blank
unless they are enabled on the Provisioning > Line tabs. See the

“15.3 Pointer Justification

Count Performance Monitoring” section on page 15-3

.

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-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-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-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.

Note

SDH path PM parameters do not increment unless IPPM is enabled. See the

“15.2 Intermediate-Path Performance Monitoring” section on page 15-2

.

HP-EB

High-Order Path Errored Block (HP-EB) indicates that one or more bits
are in error within a block.

HP-BBE

High-Order Path Background Block Error (HP-BBE) is an errored block
not occurring as part of an SES.

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-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.
