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.
2.7.406 SYNC-FREQ
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
Use an optical test set to verify the timing frequency of the line or BITS timing source and ensure that
Step 1
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.
If the reference source frequency is not outside of bounds, complete the
Step 2
Card" procedure on page 2-273
Note
Step 3 If the SYNC-FREQ condition continues to report after replacing the TCC2/TCC2P, log into the
Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC
1 800 553-2447.

It takes up to 30 minutes for the TCC2/TCC2P to transfer the system software to the newly
installed TCC2/TCC2P. Software transfer occurs in instances where different software versions
exist on the two cards. When the transfer completes, the active TCC2/TCC2P reboots and goes
into standby mode after approximately three minutes.
Default Severity: Major (MJ), Service-Affecting (SA)
