Starting a Data Terminal Loopback

The Data Terminal Loopback command (DTLB) loops the data received from

Port 1, 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.

Procedure

To perform a Data Terminal loopback:

1. From the top-level menu screen, select Test.

2. From the Test screen, select Lpbk.

Test:

Rlpbk Lpbk Ptrns

F2 F3

3. From the Loopback screen, press the key until the DTLB selection

appears on the screen.

4. Select DTLB.

Loopback:

RLB DCLB DTLB

F2 F3

Test Started appears on Line 2. If a Data Terminal 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 4-7 for valid loopback test combinations).
