DTE Loopback (DLB)

The DTE Loopback command (DLB) loops the received signal on the DTE

Drop/Insert (DSX-1) port back to the DTE without change.

Procedure

To perform a DTE loopback:

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

2. From the Test screen, select Lpbk.

3. From the Loopback screen, press the key until the DLB selection appears

on the screen.

4. Select DLB.

Test Started appears on Line 2. If a DTE 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 Table8-2, Valid Loopback Combinations, for valid loopback test

combinations).
