Definition
High-Order Path Errored Second (HP-ES) is a one-second period with one
or more errored blocks or at least one defect.
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.
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.
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.
High-Order Path Background Block Error (HP-BBE) is an errored block
not occurring as part of an SES.
High-Order Path Background Block Error Ratio (HP-BBER) 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.
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.
High-Order Path Errored Block (HP-EB) indicates that one or more bits
are in error within a block.

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.
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.
Multiplex Section Positive Pointer Justification Count, Path Generated
(MS-PPJC-Pgen) is a count of the positive pointer justifications generated
for a particular path.
