Remote Loopback Tests

The Remote Loopback tests enable you to troubleshoot your circuit by sending the following to a far-end device:

For Networks

HLine loopback up activation sequence for 10 seconds (Line Loopback Up)

HLine loopback down activation sequence for 10 seconds (Line Loopback Down)

For Channels

HV.54 activation sequence to initiate a V.54 Loop 2 (V.54 Loopback Up)

HV.54 deactivation sequence to terminate a V.54 Loop 2 (V.54 Loopback Down)

HANSI T1.403 (Annex B) activation sequence to initiate a DCLB on the remote device (FT1 Loopback Up)

HANSI T1.403 (Annex B) deactivation sequence to terminate a DCLB on the remote device (FT1 Loopback Down)

You cannot perform remote loopbacks if any of the local loopbacks are active. If you attempt to do so, the error message Invalid Test Combination appears.

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 Main Menu screen, select Test.

2.From the Test screen, select Network & DTE Tests.

3.In the Send Line Loopback field (under Remote Loopbacks), enter either Up or Down depending on the type of sequence that you want to send.

4.For the Send Line Loopback command, select Send.
