Bus Clock Circuit Status Inquiry test) passes successfully. If Test
#148 fails with an Error Code 2 through 32, refer to “TDM-CLK” to
resolve the problem. If not, continue with the following steps.
3.
Duplicated Tone-Clock circuit packs in the master port network:
Switch Tone-Clock circuit packs on the master port network via the
set tone-clock UUC
command.
Switch Tone-Clock circuit packs on the master port network via the
set tone-clock UUC
command.
For simplex Tone-Clock circuit packs in the master port network:
If
this is not a Stratum 3 system, replace the primary and secondary
(if administered) DS1 Interface circuit packs.
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
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 refer to EXP-INTF (Expansion
Interface Circuit Pack) Maintenance documentation to resolve any
errors found.
5.
Duplicated Tone-Clock circuit packs in the slave port networks:
■ Switch 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
the problem is solved
—if the count does not decrease in 15
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.
