VC-DSPPT
VC-DSP Port DSP Loopback Test (#1105)
This test is destructive.
This test verifies the connectivity of a VC-DSPPT across the TDM bus as shown
in Figure 64. 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.
