RING-GEN

Analog Ring Generator Query Test (#118)

The Analog Ring Generator Query test requests the active Tone-Clock circuit
pack to check the ringing voltage. The Tone-Clock circuit pack replies with PASS
if the ringing voltage is adequate to ring the analog phones. If not, the active
Tone-Clock circuit pack replies with a FAIL.

2. Rerun the test.
FAIL The ringing voltage is below acceptable levels. Procedure for a multicarrier
cabinet system:
1. If this is a duplicated system, then determine the active Tone-Clock circuit
2. Resolve CARR-POW alarms first, and then rerun the test.
3. Check fuse on the power distribution unit. Replace if it is open, and rerun
4. Unseat every analog circuit pack in the affected cabinet, and rerun the test.
5. If the test passes, then the ring generator is healthy, and one of the analog

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 now standby Tone-Clock
circuit pack. See ''TONE-BD (Tone-Clock Circuit Pack)'' on page
8-1173 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.

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.
When the defective analog circuit pack is found, replace it and rerun the
test. If the test still fails, proceed with Step 6.
