VC Summer Port Local TDM Loopback
Test (#1100)
This test is destructive.
This test verifies the connectivity of a VC Summer Port across the TDM bus. It
aborts if calls associated with the port are in progress. Failure of this test indicates
an on-board fault associated with the port hardware on the circuit pack. The
Loopback Test runs the following tests:
■
A Looparound test across the TDM bus.
■
A conference circuit test.
The tests are run in the above order. If the first test fails, the switch returns an
error code, and the second test is not executed.
