FAIL This failure indicates that there is no ringing voltage in the carrier where the
active tone/clock circuit pac k resides. Other carriers may or may not have
ringing voltage.
1. Unseat all analog circuit packs in the cab inet that contains the
Tone/Clock circuit pack and rerun the test.
2. 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. When the defective analog circuit pack is found, replace
it. Rerun the test. If the test still fails, go to Step 4.
3. Replace the 650A power unit, and rerun the test. If the test still fails, go
to Step 4.
4. The tone/clock may be faulty and incorrectly reporting the level of the
ringing voltage. Replace the tone/clock and rerun the test. Refer to
‘‘TONE-BD (T one-Clock Circuit Pack)’’ Maintenance documentation for
details on replacing the tone/clock circuit p ack. Rerun the test.
PASS Ringing voltage is acceptable in the cab i net c ontaining the tone/clock
circuit pack.
