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

3. Retry the command again.
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

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.
2. Retry the command at 1-minute intervals for a maximum
of 5 times.
