Chapter 2 Alarm Troubleshooting

2.7.5 ALS

For information about this alarm or condition, refer to the “Alarm Troubleshooting” chapter in the Cisco ONS 15454 DWDM Troubleshooting Guide. That guide discusses all dense wavelength division multiplexing (DWDM) alarms.

2.7.6 APC-END

For information about this alarm or condition, refer to the “Alarm Troubleshooting” chapter in the Cisco ONS 15454 DWDM Troubleshooting Guide. That guide discusses all DWDM alarms.

2.7.7 APSB

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: OCN

The APS Channel Byte Failure alarm occurs when LTE detects protection switching byte failure or an invalid switching code in the incoming APS signal. Some older SONET nodes not manufactured by Cisco send invalid APS codes if they are configured in a 1+1 protection group with newer SONET nodes, such as the ONS 15310-CL and ONS 15310-MA. These invalid codes cause an APSB alarm on the ONS 15310-CL and ONS 15310-MA.

Clear the APSB Alarm

Step 1 Use an optical test set to examine the incoming SONET overhead to confirm inconsistent or invalid K bytes. For specific procedures to use the test set equipment, consult the manufacturer. If corrupted K bytes are confirmed and the upstream equipment is functioning properly, the upstream equipment might not interoperate effectively with the ONS 15310-CL and ONS 15310-MA.

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).
