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 E1 framer.

To perform a Data Terminal loopback,

1. Press F2 to select Test from the top-level menu

screen.

2. From the Test screen, press F2 to select Lpbk.

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 4-8 for valid loopback test combinations).

Aborting Loopbacks

The Abort Loopback command stops all loopback tests

or any selected loopback test currently active on the E1
DSU/CSU.

To abort one or more loopback tests,

1. Press F2 to select Test from the top-level menu

screen.

2. From the Test screen, press F2 to select Lpbk.
