Channelized T3 Support for the Cisco AS5800
Channelized T3 Support for the Cisco AS5800
Feature Summary
The Channelized T3 (CT3) Interface Processor and Port Adapter are available on Cisco AS5800 access servers. This card provides for the aggregation of channelized interfaces into a single T3 facility. T3 support on the Cisco AS5800 allows support for 28 T1s (672 channels) per chassis.
Benefits
Channelized T3 allows for increased port density and lower cost per port, and supports a standard, widely-available, North American service. Channelized T3 (CT3) support will allow users to get the maximum benefit of double-density modem technology in the Cisco AS5800.
List of Terms
The following terms, in alphabetical order appear in this feature documentation:
DS1—The Digital Signal level for T1-class channels.
DS3—The Digital Signal level for T3-class channels.
T1—A North American standard T-Carrier, multiplexed system for channels.
T3—A North American standard T-Carrier, multiplexed system for channels.
Platforms
This feature is supported on the Cisco AS5800.
Supported MIBs and RFCs
None
Configuration Tasks
lists commands to help you configure your CT3 card.
Note
The "/" symbol is used in commands to specify a physical location. Thus 1/0/0 on a T3 port tells you where you can plug something into the Cisco AS5800. The ":" symbol is used in commands to specify a time-multiplexed division within a physical port.

To create a logical T1 controller from each of the specified timeslots of the T3 line, enter the t1 controller configuration command. Enter the no form of this command to delete the defined logical controller.
t1 ds1 controller
no t1 ds1 controllerSyntax Description
Default
None.
Command Mode
Controller configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.3(5)AA.
The purpose of this command is to convert the collection of the 28 T1 controllers that comprise the T3 controller into individual T1 controllers that the system can use. In other words, the Cisco AS5800 cannot pass data until a T1 controller is configured (using the controller t1 command), and you can't configure a T1 controller until it has been created using the t1 command.
Example
The following example configures a logical T1 controller at T1 timeslot 1 for the T3 controller located in shelf 1, slot 4, port 0. Note that you have to issue the command from the controller configuration mode.
