SYNC (Port-Network Synchronization)
3. For duplicated Tone-Clock circuit packs in the master port network,
4. Investigate any other SYNC or STRAT-3 errors.
g. This error indicates that the Expansion Interface circuit packs are
experiencing timing slips. This error will increase 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
2. Verify that all the TDM/LAN Bus cables on the backplane are
3. Check for timing loops, and resolve any loops that exist.
4. Check the Error Log for any active as well as resolved Expansion

that the bus terminator type is a ZAHF4 TDM/LAN.
For a Single Carrier Cabinet verify that the bus terminator type is a

Interchange Tone-Clock circuit packs in the slave port
networks where EXP-INTF error 2305 also occurs via the set
tone-clock UUC system technician command. The error
count for this particular error should start decrementing once

minutes the problem still persists.
If the problem still persists, switch the Tone-Clock in the slave
port network back to the previous configuration. Then,
perform a PNC interchange via the reset pnc interchange
command.
If the problem still persists, switch the PNC back to the
previous configuration via the reset pnc interchange
command. Then, switch the Tone-Clock circuit packs in the
master port network via set tone-clock UUC.
If the problem still persists, switch the Tone-Clock circuit
