Egress Adjustment Failure and Clock Source (WTOCM and PF)
In the 1830 PSS systems, channel power levels are not reported for a WTOCM monitored
port for all channels, and no channel LOS alarms are raised at the port. Symptoms of
problem channels are provisioned and actually present, but not detected at a port
monitored by WTOCM. There are no other alarms against the WTOCM pack doing the
monitoring function nor LD pack where the power readings are not reported.If this
problem occurs, you will be unable to get wavekey powers from a WTOCM monitored
cross-connect.
A sample lightpath trace for a cross-connect is displayed in Figure 3-23, “Lightpath
T
race” (p. 3-77). Note that channel power is absent. Channel power will be absent for all
channels
at this Line port if the problem manifests.
The total power at the monitored LD port where the channel powers are missing will
show a power level that is normal (see Figure 3-24, “Total Power at Monitored LD Power
Level”
(p. 3-77)):
