Voice and Control Channel Local Loop Test (#13)
This test checks the information and control channels between the Switch
Processing Element (SPE) and the EMBEDDED AUDIX port circuit. The SPE
sends a message to loop around both the information and control channels for the
port. First, the primary information (voice) channel loop back test is run.
While the primary information channel is still looped around, the Control Channel
Loop Around Test is performed. Then the Loop Around Test for the secondary
information (data) channel is performed. This test is the same as the primary
information channel loop around test.
Next, a Conference Test is implemented for the primary information channel. This
test is the same as Conference Test #6.
Only one value (Pass, Fail, or Abort) appears as a result of the four tests. If any
test fails or aborts, the sequence is stopped.
PASS
The port is using its allocated time slots correctly.
1. To be sure that this is not an intermittent problem, repeat this test up to
a maximum of 10 times to make sure it continues to pass.
2. If complaints still exist, examine the connections.

System resources required to run this test are not available. The port may
be in use. Use display port PCSSpp to determine the voice port extension
of the port. Use status station to determine the service state of the port. If
the port is in use, it is unavailable for certain tests. Refer to “Status”
commands in Chapter 8, “Maintenance Commands and Trouble-Clearing
Aids” for explanations of all possible states.
1. Wait until the port is idle before retesting and retry the command at
1-minute intervals a maximum of 5 times.
