Testing

Send Remote Line Loopback

The LTU initiates the 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. 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 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 loopback stops automatically after 10 seconds. You cannot stop the test manually.

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