Sending a Line Loopback Up or Down

Procedure

To send a Line Loopback Up or Down sequence on the network to a far-end

DSU/CSU:

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

2. From the Test screen, select Rlpbk.

Test:

Rlpbk Lpbk Ptrns

F2 F3

3. From the Rem Loopback screen, press F1 to select LLBUP (Line Loopback

Up), or press F2 to select LLBDN (Line Loopback Down).

Rem Loopback:

LLBUPLLBDN 54UP

F2 F3

The Line Loopback sequence is sent up or downstream to the far-end

DSU/CSU for 10 seconds. During this time, Sending appears on Line 2 of

the LCD, followed by Command Complete when 10 seconds have elapsed.

You can press any function key to restore the Rem Loopback screen without

affecting transmission of the loopback code.
