encapsulation. You can also choose PPP or HDLC.
Router(config-if)# encapsulation frame relay
If IP routing is enabled on the system, assign an IP address and subnet mask. For example:
Step 3
Router(config-if)# ip address 172.16.32.49 255.255.0.0
Add any configuration subcommands required to enable routing protocols and set the interface line

characteristics.
Change the shutdown state to up, which enables the interface.
Step 5
Router(config-if)# no shutdown
When you have entered all of the configuration subcommands to complete the configuration, press
Step 6
Ctrl-Z
To write the new configuration to NVRAM, type
Step 7
Router# copy running-config startup-config
After you create an interface configuration, you can modify it at any time by using the appropriate Cisco
IOS configuration commands.

Unchannelized T3 Commands

By default, a T3 interface on a 6-Port Channelized T3 line card is channelized into 28 T1 interfaces. You
must unchannelize the T3 interface in order to create a full-rate or subrate T3 interface. This section
describes the commands you use to create, customize, and test full-rate and subrate T3 interfaces. This
section describes the following:

Enter controller configuration mode.
Router(config)# controller t3 2/0/3
Router(config-controller)#
Use the t1 channel group command to create fractional T1 interfaces. In the following example, T1
interface 3 (of 28) is defined as being made up of three channel groups, numbers 19, 20, and 21.
(numbers between 0 and 23 are allowed.) The channel groups consist of a total of 24 DS0 timeslots.
Each channel group represents a separate interface.
Router(config-controller) t1 3 channel-group 19 timeslots 1-6, 10
Router(config-controller) t1 3 channel-group 20 timeslots 7,8,9
Router(config-controller) t1 3 channel-group 21 timeslots 11-24
Go to interface configuration mode for one of the channel groups. For example:
Router(config)# interface serial 2/0/3/3:19
You can now continue to Step 2.
to exit configuration mode.
