Configuration Task Overview

Configuration Task Overview
You can configure the ports of the 24-Port Channelized E1/T1 line card as channelized or unframed E1
interfaces, or as channelized T1 interfaces. To configure an E1 or T1 line card interface, perform the
following procedure:
Designate the card mode as T1 or E1.
Step 1
Configure the controller parameters and save the configuration to NVRAM.
Step 2
Create one or more serial interfaces at each active port.
Step 3
Specify the interface parameters for each port channel-group and save the configuration to NVRAM.
Step 4

E1 Configuration Examples
The examples in this section familiarize you with the line card configuration tasks and typify how you
apply the commands listed in
controller. These examples also show how to configure E1 channel-group bandwidth at any of the 24
available ports on the line card. The example steps are intended to quickly familiarize you with the
procedures you use to set up an E1 port as an E1 controller.
You must be in privileged EXEC mode to specify and configure a port as an E1 controller on any line

card port.
Configuring an E1 Controller
From the IOS global configuration mode, you use the config terminal command to enter the controller
configuration mode and to configure a card as E1 mode (see the
page 5-16
Configuring Full-Rate Unchannelized E1 Bandwidths
To configure the full-rate unchannelized E1 bandwidth at a port, you assign the maximum bandwidth
(2048 kbps) when you include unframed on the command line in controller configuration mode. The
following example shows the steps you use to create full-rate unchannelized E1 operation at any port.
Step 1 Specify a Controller: To configure the available full E1 bandwidth on an unchannelized port, you select
the E1 controller from the global configuration mode:
Router> enable
Password: (you enter your administrative password)
Router# config terminal
Enter Configuration commands, one per line. End with CNTRL/Z.
Router(config)# controller e1 2/0/0

Each time you change the card mode (from E1 to T1 or from T1 to E1), the existing running
configuration for the card interface is erased. If you want to keep a line card configuration, you
must save it before you change the card mode.
