Resource Looparound Test (#1111)
This test is destructive.
This test checks the connec tivity of the resource within MMI circuit p ack and out
to the TDM bus. The object is to test the c ircuitry that an H.221 b it stream comes
in contact with when that stream is d emultiplexed, pre-p rocessed, written to the
TDM bus and then reread (looped in the TSI), post-processed, multip lexed, and
then written back to the TDM bus for verific ation. The video, audio, and d ata
components of the bit stream are tested separately. If any one of these tests fails,
then the resource is taken out of service.
Code Description
3841 CRC4 Error (Frame checksum error)
3842 Correctable BAS (Control msg single or double bit error, but
correctable)
3843 Uncorrectable BAS (Control msg bit error -three or more bit,
uncorrectable)
3844 Protocol Error (H.221 Protocol error from endpoint detected)
