DAT-LINE (Data Line Port)
Issue 1 June 2005 879
2313 ABRT Failed to receive a response from the Maintenance/Test digital port.
1. Resolve any M/T-DIG errors.
2. Retry the command at 1-minute intervals up to 5 times.
3. If the test continues to abort, replace the Maintenance/Test circuit pack.
2314 ABRT Data line port did not respond to downlinked message.
1. Busyout the digital port being tested on the data line circuit pack. Retry
the command at 1-minute intervals up to 5 times.
2. If the test still aborts, replace the circuit pack.
2500 ABRT Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
2000 FAIL The test failed waiting for the transmitted data to be looped back.
1. Look for DATA-CHL errors in the Error Log. If present, refer to
DATA-BD (Data Channel Processor circuit pack) Maintenance
documentation.
2. Repeat this test.
3. If the test fails again, replace the Data Line circuit pack.
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.
