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.
High-Order Path Pointer Justification Count Seconds (HP-PJCS-PGen) is

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
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.
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.
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.
