Digital Looparound Test (#171)
The Digital Looparound Test checks the data line port’s ability to transmit and
receive data on the TDM Bus. Data is sent through an available Mai ntenance/Test
digital port over the TDM Bus, inter nally looped through the d ata line port bac k
onto the TDM Bus, and received ag ain by the same Maintenance/Test digital
port.
Note that only one of the two digital p orts on a Maintenance/Test circuit pac k is
used for this test, and that p ort must be the first such po rt; such as port 02. If
port 02 is in use, out-of-service, or not p resent, the test aborts. This test may fail if
the Maintenance/Test digital port used by the test is not functioning properly. If
there are any M/T-DIG errors in the Error Log, refer to the “M/T-BD” to clear them
first. This test will pass regardless of any c ustomer equipment that might be
connected to the p ort, as long as the port is not in use by the equipmen t.
2000 ABORT Response to the test request was not received within the allowable time
period.
2100 ABORT Could not allocate the necessary system resources to run this test.
