....................................................................................................................................................................................................................................
At the end of each step wait to see if the fault clears. If not, continue with the next step. It
may take several seconds for channel power out of range and channel absent alarms to
clear after each step.

particular alarmed channel is traversing.
...................................................................................................................................................................................................
2 Find the source of the channel's service and ensure that the add cross connect is
administratively up and that there are no Wavelength Tracker or channel
alarms/conditions for the associated transponder or SVAC upstream. If there are, clear
those alarms/conditions first before continuing.
...................................................................................................................................................................................................
3 Retrieve the configured topology upstream from this port to the service's ingress point to
the NE. Ensure that the physical fiber topology matches.
...................................................................................................................................................................................................
Verify that the loss in the fiber that is feeding the port is not higher than expected by
4
comparing the bulk powers ending and leaving the fiber. If the loss is higher than
expected, clean the fiber ends, and if this does not solve the problem, replace the fiber. If
this still does not solve the condition on the amplifier, the problem may be with the card
itself.
