Creating a T3, VT, or AUG Controller

A fully channelized T3
can be broken into 28 T1s...
Configuring a T3 Interface as Channelized
A T3 interface is channelized by default. Use the channelized command if you had previously made the
interface unchannelized.
[no] channelized
channelized
The no channelized command removes all channel groups from a 4-Port Channelized OC-3/STM-1 line
Caution
card interface. If you have already configured channel groups, use this command with caution.
The following example shows how to create a 4-Port Channelized OC-3/STM-1 line card interface:
Router(config)# controller T3 1/0/0.1
Router(config-controller)# channelized
Setting the Framing Type
To specify a framing type for the channelized T3 controller, use the framing command.
framing
[no] framing
The default is auto-detect.
Use the no form of the command to return the framing type to its default.
You can instruct the 4-Port Channelized OC-3/STM-1 line card to detect the framing type from the far
end and transmit that same framing type:
Router(config)# controller T3 1/0/0.1
Router(config-controller)# framing auto-detect

A T1 is broken into channel groups
to provide subscribers with rates

to a single DS0 (one timeslot).
The gray circles represent a channel
group containing timeslots 1 to 5.
