Digital Loop Around Test (#171)
The Digital Loop Around Test checks the Data Line’s ability to transmit and
receive data on the TDM Bus. Data is sent through Network Control Data
Channel 3 (data channel port 3) over the TDM Bus, internally looped through the
Data Line back onto the TDM Bus, and received again by Network Control Data
Channel 3.
If data channel 3 is in use or not administered, 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 Error Log, refer to the DATA-BD (Network Control Circuit
Pack) Maintenance documentation to clear them up first. This test passes
regardless of any customer equipment that may be connected to the port, as
long as the port is not in use by the equipment.
