FAIL The test failed because the data received did not match the data sent. This
would indicate that there is a fault somewhere in the transmit/receive path to
the TDM Bus, which will probably result in data corruption over this port. This
test may fail if the Maintenance/Test digital port used by the test is not
functioning properly.
1. Resolve M/T-DIG errors, if any.
2. Repeat Test #171.
3. If the test fails again, replace the data line circuit pack.
PASS The port can correctly transmit/receive data. Investigate user-reported
troubles on this port using other port tests and examining the ADU, external
wiring, and customer equipment.
