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.
