FAIL
(cont’d.
)
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 resid es. Other carriers may or may not have ringing voltage.
1. If this is a duplicated system, determine the active Tone-Clock circuit pack by
issuing a status system command. Make the Standby Tone-Clock circuit pack
active via the set tone-clock PC command and rerun the test.
a. If the test passes, then the trouble is with the ‘‘new’’ stand by Tone-Clock
circuit pack. Refer to “TONE-BD” for details on replacing the standby
Tone-Clock circuit pack. After the circuit pack is replaced, make this
Tone-Clock active again by issuing the set tone-clock PC command and
rerun the test.
b. If the test fails, then proceed with Step 2.
2. Unseat all analog circuit packs in the cab inet 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 c ircuit packs one at a time, and rerun the
test to determine which circuit pack is causing the problem. Replace the
defective analog circuit pac k. 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. Refer to
“TONE-BD” for details on replacing the active tone/clock circuit p ack. Rerun the
test.
PASS The analog ringing voltag e level is accep table. For a single-c arrier cabinet stac k,
ringing voltage is acceptab le in the c abinet containing the active tone/clock circ uit
pack.
