Configuring Fractional Channelized T1 Bandwidths - Cisco 10000 Series Configuration Manual

Chapter 5 24-Port Channelized E1/T1 Line Card Configuration

Configuring Fractional Channelized T1 Bandwidths

To configure an available channelized (framed) fractional T1 bandwidth on a port, you must select a T1
controller from the global configuration mode. The following example shows the procedure you use to
create a fractional channelized T1 interface.
The following two examples in this step show you how to configure all the available T1 mode port 2
Step 1
timeslots as interfaces:
Example 1:
Router(config)# controller t1 2/0/2
Router(config-controller)# channel-group 8 timeslots 1, 2, 5, 11-24
Router(config-controller)#
These commands configure port 2 time slots 1, 2, 5, and 11 to 24, of the line card in router chassis slot
2 as T1 channel-group (interface) number 8.
Example 2:
Router(config-controller)# channel-group 9 timeslots 3, 4, 6-10
Router(config-controller)#
Because you are still in the controller configuration mode, you use this command to configure T1
channel-group (interface) number 9 and remaining timeslots 3, 4, and 6 to 10 on port 2 of the line card
in router chassis slot 2.
Step 2 Specify Controller Parameters: to specify any other controller parameters you enter the controller
parameters for the controller you have selected (see
Configuration Commands" section on page
Configuring T1 Serial Interfaces
For a detailed description of how to configure, monitor, and troubleshoot a T1 serial interface, see the
Configuration Fundamentals Configuration Guide
Component Configuration
a T1 serial interface on any line-card port from the interface configuration mode.
Enter the controller configuration mode to configure the T1 controller (see the
Step 1
Controller" section on page
Use the channel-group command to assign framed T1 bandwidths to the line card ports.
Step 2
Go to interface configuration mode for any T1 channel group you created in the controller configuration
Step 3
mode and specify the serial interface channel-group number:
Router(config)# interface serial 2/0/2:20
Router(config-if)#
Step 4 Enter a value for protocol encapsulation. This example shows the command for using frame relay. You
can also choose PPP or HDLC (default).
Router(config-if)# encapsulation frame relay
Router(config-if)#
If IP routing is enabled on the system, assign an IP address and subnet mask. For example:
Step 5
Router(config-if)# ip address 10.16.32.49 255.255.240.0
