DAT-LINE (Data Line Port)
Table 8-201. Test #171 Digital Loop-Around Test — Continued
Error Test
Code Result Description / Recommendation
2500 ABORT Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
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 any M/T-DIG errors.
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.
