2. Run
test tdm P
to determine if the TDM Bus fault is still present.
3. If the TDM Bus fault is gone, replace the formerly active Expansion
Interface circuit pack.
4. Run
reset pnc interchange
again to make get the new Expansion
Interface circuit pack on the active SPE.
5. Run
test tdm P
to determine if the TDM Bus fault is still present.
6. If the TDM Bus fault is still present, replace the new Expansion Interface
circuit pack with the original suspect circuit pack, and continue on to Part
3.
7. If the TDM Bus fault has disappeared, the procedure is complete.
Part 3
1. Run
set tone-clock
to make the currently active Tone/Clock standby.
2. Run
test tdm P
to determine if the TDM Bus fault is still present.
3. If the TDM Bus fault is gone, replace the formerly active Tone/Clock circuit
pack.
4. Run
set tone-clock
again to make the new Tone/Clock circuit pack active.
5. Run
test tdm P
to determine if the TDM Bus fault is still present.
6. If the TDM Bus fault is still present, replace the new Tone/Clock circuit
pack with the original suspect circuit pack, and continue on to Part 4.
Part 4
Part 4 should be used for each individual circuit pack as listed in the previous
table. Run this procedure on all circuit packs on the standby SPE or standby
PNC. If the TDM Bus failure still exists once the standby circuit packs have all
been tested, execute either
reset system interchange
(PPN) or
reset pnc
interchange
(EPN), followed by
set tone-clock
to get the currently active circuit
packs into standby mode so that this procedure can be run on each of them.
1. Remove the inactive suspect circuit pack.
2. As in Procedure 2, determine if the backplane pins in the removed circuit
pack’s slot are bent.
3. If the pins are bent, do the following:
a. Remove power as described in the previous warning statement.
b. Straighten or replace the pins.
c. Restore power.
d. Run test tdm P to determine if the TDM Bus fault is still present.
e. If the TDM Bus failure is still present, the problem is with another
circuit pack. Reinsert the original suspect circuit pack and continue
with Part 4 for the next circuit pack.
