DETAILED STEPS
Step 1
Check the PM of the TRUNK-RX port. Verify that received power is above the optics threshold:
a) In node view (single-shelf mode) or shelf view (multishelf mode), double-click the card to display the card view.
b) For the TRUNK-RX port, double-click the card and click the Performance > Optics PM > Historical PM tabs,
choose the port in the Port drop-down list, and click Refresh.
c) Compare the refreshed PM values with the threshold (ensuring that it is above the threshold value) by clicking the
Performance > Optics PM > Current Values tabs.
d) Ensure that a proper threshold has been provisioned for the receive value. If an incorrect threshold has been set, adjust
it to a value within the allowed limits. If instead the alarm condition does not clear, move to next step.
Step 2 Verify that the Trunk-Rx port is cabled correctly, and clean the fiber connecting the faulty TXP/MXP to the Drop port
of the DWDM card (32DMX, or 40DMX). If no site cleaning practices are available, refer to the fiber cleaning procedure
in the Maintain the Node chapter of the Configuration Guide.
Step 3 Determine whether a bulk attenuator is specified by the Cisco Transport Planner design. If so, verify that the proper fixed
attenuation value has been used.
Step 4 Using a test set, check the optical power value of the Drop port of the DWDM card (32DMX, or 40DMX) connected to
the faulty TXP/MXP. If the read value is different (+1 dBm or 1 dBm) from the ANS setpoint for Padd&drop-Drop
power, move to next step.
Step 5
Look for and troubleshoot any alarm reported by the cards belonging to the OCHNC circuit destinating at the faulty
TXP/MXP. Possible alarms include amplifier Gain alarms (the

If the condition does not clear, log into the Technical Support Website at
