3. If the 2305 errors persist:
a. For Port Networks with more than one Tone-Clock circuit,
execute the command test synchronization r 10, and check
to see if new 2305 errors against TDM-CLK were reported. If
not, execute reset PNC interchange and then test
synchronization r 10 again, and recheck for new 2305
errors against TDM-CLK
b. For Port Networks with a single Tone-Clock circuit, execute
the command test synchronization r 10, and check to see if
new 2305 errors were reported.
If no new instances of the 2305 errors were logged for either test,
then enter test tone-clock UUC long clear to clear the TDM-CLK
errors. The procedure is complete.
4. For Port Networks with more than one Tone-Clock circuit:
a. Enter set tone-clock UUC to interchange the Tone-Clocks.
b. Run test synchronization r 10, and check to see if new
2305 errors are reported against the new active Tone-Clock
circuit.
c. If not, replace the standby Tone-Clock circuit. See
‘‘Replacing the IPSI or Tone-Clock Circuit Pack’’ on page
8-1666
.
If this clears the error, the problem has been resolved.
5. Replace the EI circuit pack for the active PNC.
6. If the problem is still not cleared and the IPSI or Tone-Clock circuit
pack reported in the error log has not yet been replaced, replace it.
