Procedure for a single-carrier cabinet system:
This failure indicates that there is no ringing voltage in the carrier where
the active Tone-Clock circuit pack resides. Other carriers may or may not
have ringing voltage.
1. If this is a duplicated system, use status system to determine the
active Tone-Clock circuit pack. Use set tone-clock location to
make the standby Tone-Clock circuit active, and rerun the test.
a. If the test passes, then the trouble is with the “new” stand by
Tone-Clock circuit pack. See TONE-BD (Tone-Clock Circuit)
on
page 2327 for details on replacing the standby Tone-Clock circuit
pack. After the circuit pack is replaced, use set tone-clock
location to make this Tone-Clock circuit active, and rerun the
test.
b. If the test fails, then proceed with Step 2.
2. Unseat every analog circuit pack in the cabinet that contains the
active Tone-Clock circuit pack, and rerun the test.
3. If the test passes, then the ring generator is healthy and one of the
analog circuit packs is defective. Replace the analog circuit packs one
at a time, and rerun the test to determine which circuit pack is causing
the problem. Replace the defective analog circuit pack. Rerun the
test. If the test still fails, go to Step 4.
4. Replace the WP-91153 power unit for the affected carrier, and rerun
the test. If the test still fails, go to Step 5.
5. The active Tone-Clock may be faulty and incorrectly reporting the
level of the ringing voltage. Replace the active Tone-Clock, and rerun
the test. See TONE-BD (Tone-Clock Circuit)
on page 2327 for details
on replacing the active Tone-Clock circuit pack. Rerun the test.
PASS The analog ringing voltage level is acceptable. For a single-carrier cabinet
stack, ringing voltage is acceptable in the cabinet containing the active
Tone-Clock circuit pack.
