LINE LB

The Line Loopback setting loops the T1 line back towards the network, as shown in Figure

5-3.This loopback also continues sending the incoming data toward the CPE. Choosing on allows you to test the end-to-end T1 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.
