Chapter 4 4-Port Channelized T3 Half-Height Line Card Configuration
Subrate T3 Interface
Enter controller configuration mode.
a.
Router(config)# controller t3 2/0/1
Router(config-controller)#
To create a subrate T3 interface, first create a full-rate one.
b.
Router(config-controller)# no channelized
Router(config-controller)# exit
Router(config)#
Then go into interface configuration mode, where you can use the dsu bandwidth command to
c.
create a subrate T3 interface. In this example, a subrate T3 interface is created that has a bandwidth
of 16,000 kbps.
Router(config)# interface serial 2/0/1
Router(config-if)# dsu mode digital-link
Router(config-if)# dsu bandwidth 16000
You can now continue to Step 2.
d.
Full T1 Interface
Enter controller configuration mode.
a.
Router(config)# controller t3 2/0/2
Router(config-controller)#
Use the t1 channel group command to create a T1 interface. In the following example, T1 interface
b.
1 (of 28) is defined as being made up of a single channel group, number 20 (any number between 0
and 23). This channel group consists of all 24 DS0 time slots.
Router(config-controller)# t1 1 channel-group 20 timeslots 1-24
Go to interface configuration mode for the channel group you just created.
c.
Router(config)# interface serial 2/0/2/1:20
You can now continue to Step 2.
d.
Fractional T1 Interface
Enter controller configuration mode.
a.
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
b.
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 time slots.
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:
c.
Router(config)# interface serial 2/0/3/3:19
You can now continue to Step 2.
