Demand test descriptions and error codes - Avaya Support

● If the problem still exists, switch the Tone-Clock in the slave port network back to
the previous configuration, then perform a PNC interchange using reset pnc
interchange.
● If the problem still exists, switch the PNC back to the previous configuration using
reset pnc interchange. Switch the Tone-Clock circuit packs in the master
port network using set tone-clock location.
● If the problem still exists, switch the Tone-Clock circuit packs in the master port
network back to the previous configuration using set tone-clock location.
● 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. Use list
fiber-link 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’s synchronization reference is a Tone-Clock circuit pack or a
Stratum-3 clock, follow normal escalation procedures.
If the system’s primary synchronization reference is a DS1 Interface circuit pack,
assign a different DS1 Interface as the primary reference. If the problem persists
and slip errors remain, follow the procedures in the troubleshooting section above.
6. For unduplicated Tone-Clock circuit packs in a slave port network:
● Enter set tone-clock location to switch the Tone-Clock in the master port
network.
● If the problem still exists, enter set tone-clock location to switch the
Tone-Clocks in the master port network back to their previous configuration.
Enter test tone-clock location long to test the Tone-Clock in the master
and slave port networks.
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 an Error Code 2–32, see TDM-CLK (TDM Bus Clock) 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.
