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.
IOS Idle Ordered Sets (IOS) is a count of received packets containing idle
ordered sets.
IPC A count of received packets that contain errored data code groups that have
start and end delimiters.
LBC-MIN LBC-MIN is the minimum percentage of Laser Bias Current.
LBC-AVG Laser Bias Current—Average (LBC-AVG) is the average percentage of
laser bias current.
LBC-MAX Laser Bias Current—Maximum (LBC-MAX) is the maximum percentage
of laser bias current.
LBC-MIN Laser Bias Current—Minimum (LBC-MIN) is the minimum percentage of
laser bias current.
