SYNC (Port Network Synchronization)
g. This error indicates excessive switching of system synchronization references has
occurred. When this error occurs, synchronization is disabled and the Tone-Clock circuit
pack (in the master port network) becomes the synchronization reference for the system.
Execute the following steps to resolve this error:
1. Check for timing loops, and resolve any loops that exist.
2. Test the active Tone-Clock circuit pack in the master port network using test
tone-clock location long.
Check the Error Log for TDM-CLK errors, and verify that TDM bus Clock Circuit Status
Inquiry test (#148) passes.
If Test #148 fails with Error Code 2–32, see TDM-CLK (TDM Bus Clock) to resolve the
problem. If not, continue with the following.
3. For duplicated Tone-Clock circuit packs in the master port network, enter set
tone-clock location to switch the Tone-Clocks.
For unduplicated Tone-Clock circuit packs in the master port network of a Stratum-4
(not Stratum-3) system, replace the primary and secondary (if assigned) DS1 Interface
circuit packs.
4. Investigate any other SYNC or STRAT-3 errors.
S8700-series Fiber-PNC
h. This error indicates that the Expansion Interface circuit packs are experiencing timing slips.
This error increases the bit error rates for data transmission between port networks. The
Expansion Interface circuit packs with timing slips have EXP-INTF error 2305.
1. Check the LEDs on the active Tone-Clock circuit packs in the system and verify that
the system is properly synchronized.
2. Verify that all the TDM/LAN Bus cables on the backplane are marked WP-91716. Also
for a Multi-Carrier Cabinet (MCC), check that the bus terminator type is a ZAHF4 TDM/
LAN.
For a Single Carrier Cabinet verify that the bus terminator type is a AHF110 TDM/LAN.
3. Check for timing loops, and resolve any loops that exist.
4. Check the Error Log for any active as well as resolved Expansion Interface circuit pack
errors and see EXP-INTF (Expansion Interface Circuit Pack) to resolve any errors
found.
5. Duplicated Tone-Clock circuit packs in the slave port networks:
● Interchange Tone-Clock circuit packs in the slave port networks where EXP-INTF
error 2305 also occurs using set tone-clock location. The error count for
this error should start to decrement once the problem is solved. If the count does
not decrease in 15 minutes, the problem still exists.
