Line Loopback

The Line Loopback (LLB) loops the information received on the selected interface

back to the source of the loopback. When used with a pattern test at the remote

node, LLB determines whether the problem is with the sending device or the T1

facility.

CAUTION:

This test may affect the operation of the frame relay PVCs assigned to

the selected port. While in loopback, the frame relay link will be down

so any IP data being sent while this test is active will be disrupted.

An LLB cannot be started when one of the following tests is active:

HPayload Loopback, Send Remote Line Loopback, or an active Monitor

Pattern on this network interface.

HRepeater Loopback on any other T1 interface with DS0s assigned to this

network interface.

HSend FT1 Loopback or Data Channel Loopback on the synchronous

data port.
