Information and Control Channel Local Loop Test
(#13)
This is a set of four tests that check the operation of the information and control
channels used between the SPE and the Digital Line port circuit.
NOTE:
This is an Internal Loop Around test only and does not check building wiring.
Use Test #175 for external loop around tests to the data module.
2020 ABORT The test did not run due to a previously existing error on the
specific port or a more general circuit pack error.
1. Examine Error Log for existing errors against this port or the
circuit pack and attempt to diagnose the previously existing
error.
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at one-minute intervals a maximum of 5
times.
2500 ABORT Internal System Error.
1. Retry the command at 1-minute intervals a maximum of 5
times.
1,2 FAIL The NPE of the tested port was found to be transmitting in Error
Log. This causes noisy and unreliable connections. Failure Code
1 indicates that the Crosstalk Test failed on the primary channel.
Failure Code 2 indicates that the Crosstalk Test failed on the
secondary channel.
1. Replace the circuit pack.
PASS The port is correctly using its allocated time slots.
1. To be sure that this is not an intermittent problem, repeat this
test up to a maximum of 10 times and verify that it continues
to pass.
2. If complaints still exist, examine the data module,
connections, and wiring.
