Alarm Procedures
c.
After determining the port is active, verify the signal source to the traffic card reporting the alarm.
Step 2
If traffic is being affected, delete and recreate the circuit.
Step 3
Caution
Check the far-end OC-N card that provides STS payload to the XTC card.
Step 4
Verify the cross-connect between the OC-N card and the XTC card.
Step 5
Step 6 Clean the far-end optical fiber:
a.
b.
Step 7 Replace the OC-N/XTC cards.
Note

14.4.95 PLM-V

•
A VT-payload label mismatch (PLM-V) alarm indicates that the content of the V5 byte in the SONET
overhead is inconsistent or invalid. This alarm occurs when ONS nodes interoperate with equipment that
performs bit-synchronous mapping for DS-1. ONS nodes use asynchronous mapping.
Procedure: Clear the PLM-V Alarm on the XTC-14 or XTC-28-3 Card
Verify that your signal source matches the signal allowed by the traffic card. For example, the traffic card
Step 1
does not allow VT6 or VT9 mapping.
Verify that the SONET VT path originator is sending the correct VT label value. You can find the
Step 2
SONET VT path originator using circuit provisioning steps.

14.4.96 PRC-DUPID

•
The procedural error duplicate node ID (PRC-DUPID) alarm indicates that two identical node IDs exist
in the same ring. The ONS 15327 requires each node in the ring to have a unique node ID.

If the State column lists the port as INCOMPLETE, wait 10 minutes for the ONS 15327 to fully
initialize. If INCOMPLETE does not change after full initialization, login to
http://www.cisco.com/TAC for more information or call the Cisco Technical Assistance Center to
report a service-affecting problem (1-800-553-2447).
Deleting a circuit may affect traffic.
Clean the fiber according to local site practice.
If no local practice exists, use a CLETOP Real-Type or equivalent fiber-optic cleaner and follow the
instructions accompanying the product.
When you replace a card with an identical type of card, you do not need to make any changes to
the database.
