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 resides. Other carriers may or may not have
ringing voltage.
1. If this is a Duplicated Option 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 "new" Standby
Tone-Clock circuit pack. Refer to TONE-BD (Tone-Clock Circuit
Pack) Maintenance documentation 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 cabinet that contains the Active
Tone/Clock circuit pack and rerun the test.
3. If the test passes, then the Analog 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. 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 Maintenance documentation for details on
replacing the active tone/clock circuit pack. Rerun the test. If the test
still fails, escalate the problem.
PASS FOR A MULTI-CARRIER CABINET SYSTEM.
The analog ringing voltage level is acceptable.
FOR A SINGLE-CARRIER CABINET SYSTEM.
For a single-carrier cabinet stack, ringing voltage is acceptable in the
cabinet containing the active tone/clock circuit pack.
