Chapter 20 Configuring T1/E1 Controllers

Configuring E1 Controllers

	Command	Purpose
Step 3
	card type {e1 t1} slot subslot	Sets the card type. The command has the following syntax:
		• slot—Slot number of the interface.
	Example:	• subslot—0.
	Router(config)# card type e1 0 0
		When the command is used for the first time, the configuration takes
		effect immediately. A subsequent change in the card type does not take
		effect unless you enter the reload command or reboot the router.
		Note When you are using the card type command to change the
		configuration of an installed card, you must first enter the no card
		type {e1 t1} slot subslot command. Then enter the card type {e1
		t1} slot subslot command for the new configuration information.
Step 4
	exit	Exit configuration mode.
	Example:
	Router(config)# exit
	Router#

Configuring E1 Controllers

Perform a basic E1 controller configuration by specifying the E1 controller, entering the clock source, specifying the channel-group, configuring the serial interface, configuring PPP encapsulation, and enabling keepalive packets. You might also need to enter other configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface.

Note In the following procedure, press the Return key after each step unless otherwise noted. At any time, you can exit the privileged level and return to the user level by entering disable at the Router# prompt.

To configure the E1 controllers, complete the following steps in the global configuration mode:

	Command	Purpose
Step 1
	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3
	controller e1 slot/port	Specifies the controller that you want to configure.
	Example:
	Router(config)# controller e1 0/0
	Router(config-controller)#
