Remote Send Line Loopback

The local unit initiates this test by sending a line loopback Up or Down command
to the remote unit for 10 seconds. When the remote unit detects the loopback Up
command, it puts itself in line loopback and lights the front panel Test LED. The
remote unit remains in loopback until it receives a loopback Down command or the
remote unit's test timeout value is exceeded.

The Send Line Loopback tests both units. External equipment can be used to
verify the link.

Procedure

To run a Remote Send Line loopback:

1. Position the cursor at the Up or Down selection next to Send Line Loopback on

the Network & DSX-1 Tests screen.

2. Press the spacebar to select either Up or Down.

3. Position the cursor at the Send command next to Up or Down selection.

4. Press Enter.

The local unit stops sending the loopback command automatically after
10 seconds. You cannot stop the Remote Send Line Loopback test manually.

The Remote Send Line Loopback cannot be started when any other loopback or a
Send and Monitor 511 test is active on the network interface.
