Voice and Control Channel Local Loop Test (#13)
This test checks the information and control channels between the server the
EMBEDDED AUDIX port circuit. The server 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
Looparound test is performed. The loop-around test for the secondary
information (data) channel is then performed. This test is the same as the primary
information channel’s 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) is generated as a result of the four tests run.
If any test fails or aborts, the sequence is stopped.
PASS The port is using its allocated time slots correctly.
1. To verify that this is not an intermittent problem, repeat this test up to 10
times, and make sure it continues passing.
2. If complaints still exist, examine the connections.
