Line Loopback
The local 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.

Network Physical Tests
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:
Payload Loopback, Send Remote Line Loopback, or an active Monitor Pattern
on this network interface.
Send Pattern test on this network interface.
