Digital Loop Around Test (#171)
The Digital Loop Around Test checks the Data Line’s ab ility to transmit and
receive data on the TDM Bus. Data is sent through Data Channel 3 (d ata channel
port 3) over the TDM Bus, internally looped through the Data Line bac k onto the
TDM Bus, and received again b y Data Channel 3.
If data channel 3 is in use or not administ ered, this test aborts. This test may fail if
Network Control Data Channel 3 is not functioning properly. If there are any
DATA-CHL errors in the E rr or Log, refer to the DATA-BD (Data Channel Processor
circuit pack) Ma intenance documentation to c lear them up first. This test passes
regardless of any customer eq uipment that may be conn ected to the port, as
long as the port is not in use b y the equipment.

Result Description/ Recommendation
1000 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
2. Escalate the problem if the test continues to abort.
1006 ABORT The test did not run due to an already existing error on this port (Error Type
769).
1. Refer to the procedure for Error Type 769. If Error Type 769 still occurs
on this port, replace the circuit pack.
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.
1. Retry the command at 1-minute intervals a maximum of 5 times.
7 FAIL Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
PASS The hardware port state is consistent with the software state. User-reported
troubles on this port should be investigated using other port tests,
examining the ADU, external wiring, and customer equipment.
