Page 92: Using Loopback Commands
The syntax of the loopback diagnostic command is as follows: • loopback [diagnostic] Set the first T1 into diagnostic loopback. Cisco 7200 Series Routers: Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t1 2/0... - Page 93 Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t1 1/0 Router(config-controller)# loopback diagnostic Cisco 7500 Series Routers: Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t1 2/2/0 Router(config-controller)# loopback diagnostic In the preceding examples, the loopback diagnostic command loops the outgoing transmit signal back to the receive signal and sends an alarm indication signal (AIS) to the network.
