Resource Loop-Around Test (#1111)
This test is destructive.
This test checks the connectivity of the resource within MMI circuit pack and out to the TDM
bus. The object is to test the circuitry that an H.221 bit stream comes in contact with when that
stream is demultiplexed, pre-processed, written to the TDM bus and then reread (looped in the
TSI), post-processed, multiplexed, and then written back to the TDM bus for verification. The
video, audio, and data components of the bit stream are tested separately. If any one of these
tests fails, the resource is taken out of service.
