Configuring A T3 Interface As Unchannelized - Cisco 10000 Series Configuration Manual

Chapter 4 4-Port Channelized T3 Half-Height Line Card Configuration

Configuring a T3 Interface as Unchannelized

The default value for a T3 interface is channelized. 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
After entering controller configuration mode, you can configure the T3 interface as unchannelized (clear
channel) by entering the no channelized command. Use the channelized command to return the
interface to its default (channelized).
[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.
In the following example, an unchannelized T3 interface is created:
Router(config)# controller T3 1/0/0
Router(config-controller)# no channelized
Specifying the DSU Mode
To specify a DSU mode for a selected T3 interface, use the dsu mode command from interface
configuration mode. This command configures the line card to emulate a manufacturer's proprietary
multiplexing scheme.
[no] dsu mode
verilink-lowbit
The default DSU mode is cisco.
Use the no form of the command to return the DSU mode to its default.
In the following example, the DSU mode is set to cisco:
Router(config)# interface serial 1/0/0
Router(config-if)# dsu mode cisco
Specifying Subrate T3 Bandwidth
To specify subrate T3 bandwidth, use the dsu bandwidth bandwidth command from interface
configuration mode.
[no] dsu bandwidth bandwidth
Where bandwidth is a numeric value between 0 and 44210 kbps.
The default bandwidth is 44210 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 time slot size for the current DSU mode.
To use the dsu bandwidth command, the remote side of the connection must also support the same DSU
modes.
