Test Started appears on Line 2. If a Data Channel loopback is already in progress, the Already Active message appears. If an invalid combination of loopbacks is in progress, the error message Invld Test Combo appears (see Table 4-8, Valid Loopback Combinations, for valid loopback test combinations).

Starting a Data Terminal Loopback

The Data Terminal Loopback command (DTLB) loops the data received from the selected port, for all DS0 channels allocated to the port, back out of the port. This loopback occurs after the data passes through the port circuitry but before it reaches the T1 framer.
