Cisco ONS 15454 SDH Installation and Operations Guide, R3.3
May 2002
Chapter 8 SDH Performance Monitoring
SDH Performance Monitoring for Optical Cards
Table 8-21 Pointer Justification Count PMs for the STM-1 Card, Near-End
Parameter Definition
Note On CTC, the count fields for MS-PPJC and MS-NPJC PMs appear white and blank unless they
are enabled on the Provisioning > Line tabs. See the Enable Pointer Justification Count
Performance Monitoring procedure on page 8-17.
MS-PPJC-Pdet
Multiplex Section, Positive Pointer Justification Count, Path Detected
(MS-PPJC-Pdet) is a count of the positive pointer justifications detected
on a particular path on an incoming SDH signal.
MS-NPJC-Pdet
Multiplex Section, Negative Pointer Justification Count, Path Detected
(MS-NPJC-Pdet) is a count of the negative pointer justifications detected
on a particular path on an incoming SDH signal.
MS-PPJC-Pgen
Multiplex Section, Positive Pointer Justification Count, Path Generated
(MS-PPJC-Pgen) is a count of the positive pointer justifications generated
for a particular path.
MS-NPJC-Pgen
Multiplex Section, Negative Pointer Justification Count, Path Generated
(MS-NPJC-Pgen) is a count of the negative pointer justifications
generated for a particular path.
Table 8-22 High-Order VC4 and VC4-Xc Path PMs for the STM-1 Card, Near-End
Parameter Definition
Note SDH path PMs will not count unless IPPM is enabled. For additional information, see the
Enabling Intermediate-Path Performance Monitoring section on page 8-14. The far-end
IPPM feature is not supported in SDH Software R3.3. However, SDH path PMs can be
monitored by logging into the far-end node directly.
HP-EB
High-Order Path Errored Block (HP-EB) indicates 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 a severely errored second (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% errored blocks or at least one defect. SES is a
subset of ES.
HP-UAS
High-Order Path Unavailable Seconds (HP-UAS) is a count of the seconds
when the VC path was unavailable. A low-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.
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.
