LINE LB
The Line Loopback setting loops the T1/E1 line back toward the network, as shown in Figure
9-16. This loopback also continues sending the incoming data toward the CPE. Choosing on
allows you to test the end-to-end T1/E1 circuit path from the far end. Choosing off disables
the loopback and restores the normal signal path in both directions. If the WAN is in loopback
due to a remote device, the loopback will be dropped if you choose on.

LOCAL LB
The Local Loopback setting allows you to loop the full T1/E1 line back toward the CPE, as
shown in Figure 9-16. This loopback also continues sending CPE data toward the network.
Choosing on allows you to test the local system. Choosing off disables the loopback and
restores the normal signal path in both directions. If the WAN is in loopback due to a command
from a remote device, the loopback will be dropped if you choose on.
