FAIL
(cont’d.)
5. 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, proceed with Step
6.
6. Since the test still fails, the Analog Ring Generator is defective.
Replace the Analog Ring Generator as follows:
a. Open the PDU compartment door. The door is hinged on the right
and has a magnetic latch on the left.
b. If the reset button on the Analog Ring Generator is out, press it in.
c. Originate calls to several analog stations on different port circuit
packs in different carriers in the affected port network.
d. If called stations ring, the fault is cleared. Proceed to Step f. If no
stations ring, replace the Analog Ring Generator. To replace the
Analog Ring Generator, first disconnect the output (P6) and input
(P7) connectors from the Analog Ring Generator and then remove
the two screws at the base of the Analog Ring Generator.
e. Replace the Analog Ring Generator, secure it with the two screws
at the base, and replace the P6 and P7 connectors (P6 goes on
top).
f. Rerun the test. If the test still fails, proceed to Step 7.
7. 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 (Tone-Clock Circuit Pack) Maintenance
documentation for details on replacing the tone/clock. Rerun the test.
If the test still fails, escalate the problem.
