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.

ABORT
Could not seize the resources to run the test. Other maintenance is running on
the active Tone-Clock circuit pack.
1. Wait for the green LED on the active Tone-Clock circuit pack to go out; use
the status port-network command to determine the active Tone-Clock
circuit pack.
2. Rerun the test. If the test aborts again, see
‘‘TDM-CLK (TDM Bus Clock)’’ on
2000
ABORT
Response to the request was not received within the allowable time period.
1. Look for TDM-CLK errors and alarms. Resolve every other Tone-Clock
problem first.
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
pack by issuing a status port-network 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 now standby Tone-Clock
circuit pack. See
‘‘TONE-BD (Tone-Clock Circuit)’’ on page 8-1659
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. 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 the
test. If the test still fails, then an analog line circuit pack could be defective
and causing the ring generator and/or fuse to fail.
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
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.
