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. This is an
Internal Looparound test only and does not check building wiring. See Test #175
for external loop around tests to the data module.
The SPE 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.
With the port still in loop-around mode, the S channel Looparound Test is
performed next. This test consists of sending four different transparent patterns
to the on-board microprocessor, receiving them back, and comparing them.
The third test is a Looparound Test for the secondary information channel. It is
performed only if a secondary data module is assigned to the port.
The fourth test is a Conference Test of the primary channel. This test is the same
as the Analog Line Conference Test #6.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-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.

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 a
maximum of 10 times and verify that it continues to pass.
2. If complaints still exist, examine the data module, connections, and wiring.
