Transponder Network Port Loss of Frame
Corrective Action
NOTICE
Service-disruption hazard
A cold reset, reseat, or replacement of a card is service impacting if the card is currently
carrying services. To determine if any services are currently carried over a card, perform
the procedure “Reseating a Card” (p. 3-19).
If
there are services currently carried over the card, it may be best to wait for a
maintenance window before resetting, replacing, or reseating the card.
The following procedure details the corrective action for an LOF against the network
port.
At the end of each step wait to see if the fault clears. If not, continue with the next step.

1
Perform the procedure “Path Power Trace” (p. 3-8) to identify the probable network
trouble-point for the light-path. The procedure guides the user through the investigation
and resolution of the problem tracing back through to the source of the light path.
If the problem is the head end of the path (the transponder card at the source) then:
1. Check the add NE for conditions against the OT port and resolve any issues.
2. Verify that the source card network-facing port is administratively UP and
transmitting.
3. Verify that the add path is correctly fibered. If the add element has no transponder,
verify that the light source is compatible.

2
Verify that the far end transponder port to which the alarmed port is connected is of the
same type, and that the configuration of both ports is the same (for example, that the
encapsulation mode is the same for both).
