Error Test
Code Result Description / Recommendation
1020 ABORT Test disabled via background testing. Use status data-module command to
determine when the data module is available for testing.
2000 ABORT Response to the test request was not received within the allowable time period.
1. Retry the command at 1-minute intervals up to 5 times.
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
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1, 2 FAIL The NPE of the tested port was found to be transmitting in Error Log. This will
cause 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 up
2. If complaints still exist, examine the data module, connections, and wiring.
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 Avaya MultiVantage™ software and the Digital Line
port circuit. This is an Internal Loop around test only and does not check building
wiring. See Test #175 for external loop around tests to the data module.
The Avaya MultiVantage™ software first sends a message to the on-board
microprocessor to loop around both the information and control channels for the
port. Then, the primary information channel loop back test is run. The test is
performed by sending a digital count from the Tone-Clock circuit pack on the
primary channel time slot and receiving the same digital count with a
General-Purpose Tone Detector. The digital count looks like transparent data to
the on-board microprocessor.
