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.
