Definition
Chapter 14, "Alarm
Chapter 6, "Circuits and Tunnels."
In a 1+1 protection scheme for a working card, Protection Switching
Count (PSC) is a count of the number of times service switches from a
working card to a protection card plus the number of times service
switches back to the working card.
For a protection card, PSC is a count of the number of times service
switches to a working card from a protection card plus the number of
times service switches back to the protection card. The PSC PM is only
applicable if revertive line-level protection switching is used.
Note
Protection Switching Duration (PSD) applies to the length of time, in
seconds, that service is carried on another line. For a working line, PSD
is a count of the number of seconds that service was carried on the
protection line.
For the protection line, PSD is a count of the seconds that the line was
used to carry service. The PSD PM is only applicable if revertive
line-level protection switching is used.

Justification Count (NPJC) PMs appear white and blank unless they are enabled on the

Positive Pointer Justification Count path-detected (PPJC-Pdet) is a count
of the positive pointer justifications detected on a particular path on an
incoming SONET signal.
Negative Pointer Justification Count path-detected (NPJC-Pdet) is a count
of the negative pointer justifications detected on a particular path on an
incoming SONET signal.
Positive Pointer Justification Count path-generated (PPJC-Pgen) is a
count of the positive pointer justifications generated for a particular path
to reconcile the frequency of the SPE with the local clock.
Negative Pointer Justification Count path-generated (NPJC-Pgen) is a
count of the negative pointer justifications generated for a particular path
to reconcile the frequency of the SPE with the local clock.
