Configuring A Serial Interface - Cisco 10000 Series Configuration Manual

Chapter 5 24-Port Channelized E1/T1 Line Card Configuration
Example 1: In the following example, you select chassis slot 2 E1 controller:
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
Router(config-controller)#
Example 2: In the following example, you select chassis slot 2 T1 controller:
Router> enable
Password: (you enter your administrative password)
Router# config terminal
Enter Configuration commands, one per line. End with CNTRL/Z.
Router(config)# controller t1 2/0/0
Router(config-controller)#

Configuring a Serial Interface

For each port you configure at the controller configuration level, you must also configure various
associated serial interface parameters for each channel group you previously created at that port. To
configure 24-Port Channelized E1/T1 line card serial interfaces for their serial interface parameters, you
must be in the interface configuration mode. To specify interface parameters for any channel group you
previously created, use the following syntax:
[no] interface serial slot/subslot/port:channel-group
Use the no form of the channel-group command (see the
page 5-21
an E1 or T1 port, respectively, and a channel group you previously provisioned.
Example:
Router> enable
Password: (you enter your administrative Password)
Router# config terminal
Enter Configuration commands, one per line. End with CNTRL/Z.
Router(config)# interface serial 2/0/0:20
Router(config-if)#
These commands establishes the interface configuration mode for the 24-Port Channelized E1/T1 line
card in router chassis slot 2, subslot 0, port 0 and channel-group 20. When your prompt changes to
Router(config-if)#
Note You can not specify a channel group until you have first selected an E1 or T1 controller.
Controller Configuration Commands
After installing a 24-Port Channelized E1/T1 line card into a router chassis slot, you configure it in
controller configuration mode. You can also preconfigure a router chassis slot and the line-card ports for
E1 or T1 mode, and as serial interfaces, before you install a line card into the preconfigured slot (see the
"Preconfiguring a Line Card" section on page
The controller configuration commands listed in
preconfigure or configure a 24-Port Channelized E1/T1 line card controller. You also use these
commands to provide the line card with its system functionality. To configure the line card at the E1 or
T1 controller level, you perform the following general procedure:
OL-8834-04
and the "Specifying T1 Channel Groups" section on page
you can configure the channel group serial interface parameters.
"Specifying E1 Channel Groups" section on
5-22) to disable a serial interface at
