Procedure

To perform a Line loopback:

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

2. From the Test screen, select Lpbk.

Test:

Test Started appears on Line 2. If a Line 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).
