■ If the problem still persists, switch the Tone-Clock circuit
packs in the master port network back to the previous
configuration via
set tone-clock UUC
.
■ Replace the active Expansion Interface circuit pack in the
master port network.
■ In a CSS configuration, replace the Switch Node Interface
circuit pack connected to the active Expansion Interface
circuit pack in the master port network. The
list fiber-link
command can be used to determine the Switch Node
Interface circuit pack that is connected to the active
Expansion Interface circuit pack in the master port network.
■ If the system synchronization reference is a Tone-Clock
circuit pack or the Stratum 3 Clock, follow normal escalation
procedures. If the system synchronization reference is a DS1
interface circuit pack, administer a different DS1 interface
circuit pack as the primary synchronization reference. If the
problem still is not resolved and any slip errors remain, follow
the procedures described in the troubleshooting section
above.

Simplex Tone-Clock circuit packs in the slave port networks:
■ 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
packs in the master port network back to the previous
configuration via
set tone-clock UUC
. Test the Tone-Clock
circuit packs in the master and slave port networks via the
test tone-clock UUC long
command. Check the Error Log
for TDM-CLK errors and verify that TDM Bus Clock Test #148
(TDM 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.
■ If the master and slave Tone-Clock circuit packs
do not
fail
TDM Bus Clock Test #150 (TDM Bus Clock PPM Inquiry test),
replace the Expansion Interface circuit packs that have
EXP-INTF error 2305.
■ If the system synchronization reference is a Tone-Clock
circuit pack and the master Tone-Clock circuit pack fails
TDM Bus Clock Test #150, follow the steps listed in
“TDM-CLK” to replace the master Tone-Clock circuit pack.
■ If the system synchronization reference is a DS1 interface
circuit pack and the master Tone-Clock circuit pack fails
TDM Bus Clock Test #150, the primary or secondary (if
administered) synchronization references are not providing
valid timing signals for the system. Check the system
