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.

Parameter Definition
Note For information about troubleshooting SNCP switch counts, refer to the alarm troubleshooting
information in the Cisco ONS 15454 SDH Troubleshooting Guide. For information about
creating circuits that perform a switch, see
Chapter 10, “Circuits and Tunnels.”
MS-PSC (MS-SPRing) For a protect line in a two-fiber ring, Multiplex Section Protection
Switching Count (MS-PSC) refers to the number of times a protection
switch has occurred either to a particular span’s line protection or away
from a particular span’s line protection. Therefore, if a protection switch
occurs on a two-fiber MS-SPRing, the MS-PSC of the protection span to
which the traffic is switched will increment, and when the switched traffic
returns to its original working span from the protect span, the MS-PSC of
the protect span will increment again.
MS-PSC (1+1 protection) In a 1+1 protection scheme for a working card, Multiplex Section
Protection Switching Count (MS-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, MS-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 MS-PSC PM is
only applicable if revertive line-level protection switching is used.
MS-PSD For an active protection line in a two-fiber MS-SPRing, Multiplex Section
Protection Switching Duration (MS-PSD) is a count of the number of
seconds that the protect line is carrying working traffic following the
failure of the working line. MS-PSD increments on the active protect line
and MS-PSD-W increments on the failed working line.
