Installing and Configuring Processor Modules

E1 Configuration

The following steps describe a basic E1 configuration. Press the Return key after each step.

Step 1 At the privileged-mode prompt, enter the configuration mode and specify that the console

terminal will be the source of the configuration subcommands as follows:

Router# conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Step 2 At the prompt, specify the controller to configure by entering the subcommand cont,

followed by e1, and slot/applique (interface processor slot number/applique). The example

that follows is for the MIP in interface processor slot 4, applique 1:

Router(config)# cont e1 4/1

Step 3 At the prompt, specify the framing type.

Router(config-controller)# framing crc4

Step 4 At the prompt, specify the linecode format.

Router(config-controller)# linecode hdb3

Router(config-controller)#

%CONTROLLER-3-UPDOWN: Controller E1 4/1, changed state to up

Router(config-controller)#

Step 5 At the prompt, specify the channel-group modification command, channel-group and

timeslots to be mapped. The example shows channel-group 0 and timeslots 1, 3 through 5,

and 7 selected for mapping.

Router(config-controller)# channel-group 0 timeslots 1,3-5,7

Router(config-controller)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial4/1:0, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial4/1:0, changed state to up

Router(config-controller)#

Step 6 At the prompt, specify the interface, serial, slot, applique, and channel-group to modify.

Router(config-controller)# int serial 4/1:0

Step 7 At the prompt, assign an IP address and subnet mask to the interface with the ip address

configuration subcommand as in the following example:

Router(config-if)# ip address 1.1.15.1 255.255.255.0

Router(config-if)#

Step 8 Add any additional configuration subcommands required to enable routing protocols and

adjust the interface characteristics.

Step 9 After including all of the configuration subcommands, and to complete the configuration,

enter Ctrl-Z (hold down the Control key while you press Z) to exit the configuration mode.

Step 10 Write the new configuration to memory as follows:

Router# write memory

The system will display an OK message when the configuration is stored.
