Remote Loopback Tests

The Remote Loopback tests enable you to troubleshoot
your circuit by sending the following to a far-end device:
Line loopback up activation sequence for
10 seconds (LLBUP)
Line loopback down activation sequence for
10 seconds (LLBDN)
You cannot perform remote loopbacks if any of the
local loopbacks are active. If you attempt to do so, the
error message Invld Test Combo (Invalid Test
Combination) appears.
