Alarm Troubleshooting
DETAILED STEPS
To clear the condition, clear alarms related to failures of the primary source, such as the
or the SYNCSEC , on page 411

SYNC-FREQ

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Object: TRUNK
The Synchronization Reference Frequency Out of Bounds condition is reported against any reference that is
out of the bounds for valid references. The login node fails the reference and chooses another internal or
external reference to use.
Clear the SYNC-FREQ Condition
SUMMARY STEPS
1. Use an optical test set to verify the timing frequency of the line or BITS timing source and ensure that it
falls within the proper frequency. For specific procedures to use the test set equipment, consult the
manufacturer.
2. If the reference source frequency is not outside of bounds, complete the
page 453
DETAILED STEPS
Step 1
Use an optical test set to verify the timing frequency of the line or BITS timing source and ensure that it falls within the
proper frequency. For specific procedures to use the test set equipment, consult the manufacturer.
For BITS, the proper timing frequency range is approximately 15 PPM to 15 PPM. For optical line timing, the proper
frequency range is approximately 16 PPM to 16 PPM.
Step 2
If the reference source frequency is not outside of bounds, complete the
for the control card.
It takes up to 30 minutes for the control card to transfer the system software to the newly installed control card.
Note
Software transfer occurs in instances where different software versions exist on the two cards. When the transfer
completes, the active control card reboots and goes into standby mode after approximately three minutes.
If the condition does not clear, log into the Technical Support Website at
for more information or call Cisco TAC (1 800 553-2447).
