FAIL
The ringing voltage is below acceptable levels. For a multicarrier cabinet 
system:
1. If this is a duplicated system, use status port-network to 
determine the active Tone-Clock circuit pack.
2. Use set tone-clock location to make the standby Tone-Clock 
circuit pack active 
3. Rerun the test.
a. If the test passes, the trouble is with the now standby Tone-Clock 
circuit pack. See 
details on replacing the standby Tone-Clock circuit pack. After the 
circuit pack is replaced, use set tone-clock location to 
make this Tone-Clock active again, and rerun the test.
b. If the test fails:
4. Resolve CARR-POW alarms first, and then rerun the test.
5. 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.
6. Unseat every analog circuit pack in the affected cabinet, and rerun the 
test.
7. 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.
