Control Channel Loop Around Test (#52)
This test queries the circuit pack for its circuit pack code and vintage and verifies
its records.
FAIL No ringing current is detected. The ringing application circuitry on this
circuit pack probably is not healthy.
1. Retry the command again.
2. If the test continues to fail, look for RING-GEN error in Error Log.
a. If there are RING-GEN errors, refer to the RING-GEN Maintenance
documentation and try to resolve any problem(s).
b. If there are no RING-GEN errors, replace the circuit pack.
3. Retry the command again.
4. If the test continues to fail, escalate the problem.
PASS Ringing current is detected or this vintage of the Analog Line circuit pack
does not support the Ringing Application Circuit Test. Analog Line circuit
packs that DO NOT support Test #51 include TN712 Vintage 13 and
earlier and TN742 Vintage 3 and earlier.
any NO
BOARD
This is normal if the test is being done when (a) the circuit pack is not
physically in the system or (b) the system is booting up. Otherwise, there is
some inconsistency between the physical configuration and the data kept
in the system.
1. Verify that the circuit pack is physically in the system. Verify that the
system is not in a stage of booting up. Retry the command at
one-minute intervals for a maximum of five times. If the test continues
to return NO BOARD, escalate the problem.
