VC DSP Port Local TDM Loopback Test (#1104)
This test is destructive.
This test verifies the connectivity of a VC DSP Port across the TDM bus. It aborts
if calls associated with the port are in progress. Failure of this test indic ates an
on-board fault associated with the port hardware on the circ uit pack. The
Loopback Test runs the following tests:
1. A Looparound test across the TDM bus.
2. A conference Circuit Test.
The tests are run in the above order; if one test fails, an error c ode is returned
and the remaining tests in the seq uence are not executed.
PASS The port is correctly using its allocated time slots.
1. To be sure that this is not an intermittent problem, repeat this test a
maximum of 10 times.
2. If complaints still persist, examine the station, connections, and wiring.
