To set a local loopback on an E1 line, use the loopback local TUG-3 configuration command.

Router(config)# controller sonet 6/0

Router(config-controller)# au-4 tug-3 2

Router(config-ctrlr-tug3)# tug-2 4 e1 1 loopback local

Router(config-ctrlr-tug3)#

To set a network line loopback on an E1 line, use the loopback network line TUG-3 configuration

command.

Router(config-ctrlr-tug3)# tug-2 4 e1 1 loopback network line

Router(config-ctrlr-tug3)#

To set a network payload loopback on an E1 line, use the loopback network payload TUG-3

configuration command.

Configuring the Serial Interfaces

The following sections describe how to enable an interface and specify IP routing. You may also need

to enter other configuration commands, depending on your system configuration requirements. For

descriptions of configuration commands and the configuration options available, refer to the appropriate

software publications listed in the “Related Documents” section on page 54.

A serial interface is automatically created for each T-1and E1 configured. Table 10 lists the command

syntax for the selected framing.
