OT port. At the end of each step wait to see if the fault clears. If not, continue with the
next step.
...................................................................................................................................................................................................
Retrieve power level reading on the local OT port.

...................................................................................................................................................................................................
2 If power level is low on the DWDM facing port, identify the associated OCh trail and
verify the power levels along the OCh trail.
...................................................................................................................................................................................................
Identify the farthest upstream point relative to the far end OTUk port at which power
3
level falls within the expected range.
...................................................................................................................................................................................................
Check the alarms/conditions on the node located in Step 3 or the node immediately

upstream from point identified in
...................................................................................................................................................................................................
5 Correct the problem identified in
...................................................................................................................................................................................................
If all power levels along the OCh trails fall within the target range, locate the fiber
6
connected directly to receiver of the port which detects SSFODUEGR condition.
...................................................................................................................................................................................................
7 Clean the fiber.
...................................................................................................................................................................................................
If cleaning the fiber does not clear the problem, replace the fiber.
