Creating a T3, VT, or AUG Controller
Entering Controller Configuration Mode for T3
To create an unchannelized T3 interface, you must first enter controller configuration mode for the T3
controller you want to configure.
controller T3 slot/sub-slot/port.path
Where path specifies the T3 interface number.
The following example shows how to enter controller configuration mode:
Router(config)# controller T3 1/0/0.1
Router(config-controller)#
Configuring a T3 Interface on a SONET-Framed Controller as Unchannelized
If the 4-Port Channelized OC-3/STM-1 line card is configured for SONET framing, you must unchannelize
the T3 interface to create a full-rate or subrate T3 interface.
You can configure the T3 interface as unchannelized (clear channel) by entering the no channelized
command.
[no] channelized
The no channelized command removes all channel groups from a channelized T3 interface. If you have
Caution
already configured channel groups, use this command with caution.
Use the channelized command to return the interface to its default. The default value for a T3 interface
is channelized.
In the following example, an unchannelized T3 interface is created:
Router(config)# controller T3 1/0/0.1
Router(config-controller)# no channelized
Implementing Subrate T3
You can implement subrate T3 by specifying the bandwidth for an unchannelized T3 interface. To do so,
use the dsu bandwidth bandwidth command from interface configuration mode.
dsu bandwidth bandwidth
[no] bandwidth bandwidth
Where bandwidth is a numeric value between 0 and 44,210 kbps.
The default bandwidth is 44,210 kbps.
To return to the default bandwidth, use the no form of this command.
When you specify a value, the software sets the bandwidth to the closest acceptable bandwidth based on
the timeslot size for the current DSU mode.
For you to properly use this command, the remote side of the connection must have a Cisco 7200 router
or Cisco 7500 router with a PA-T3 or PA-2T3 port adapter or a T3 DSU supported by the dsu mode
command.
In the following example, a bandwidth of 16,000 kbps is specified:
Router(config)# interface serial 1/0/0.1
Router(config-if)# dsu bandwidth 16000
