Syntax:

Cisco 7200 Series and Cisco 7500 Series Routers
controller {t1 | e1} slot/port

Cisco AS5200 and AS5300 Access Servers and Cisco 4000 Series Routers
controller {t1 | e1} number

Cisco AS5800 Access Servers

Cisco AS5800 Access Servers with Channelized T3 Interface Processor (CT3IP)
controller t3 dial-shelf/slot/t3-port

Cisco 7500 Series Cisco 7500 Series Routers with Channelized T3 Interface Processor (CT3IP)
controller t3 slot/port-adapter/port


Syntax Description:

t1 T1 controller
e1 E1 controller
slot/port Backplane slot number and port number on the interface. See your hardware installation manual for the specific values and slot numbers.
number Network processor module (NPM) number, in the range 0 through 2.
dial-shelf Dial shelf chassis in the Cisco AS5800 access server containing the interface card.
t3-port T3 port number. The only valid value is 0.
:t1-num T1 timeslot in the T3 line. The value can be from 1 to 28.

Command Description:

To configure a T1 or E1 controller and enter controller configuration mode, use the controller command in global configuration mode.

T1 or E1 Fractional Data Lines:

This command is used in configurations where the router or access server is intended to communicate with a T1 or E1 fractional data line. Additional parameters for the T1 or E1 line must be configured for the controller before the T1 or E1 circuits can be configured by means of the interface global configuration command.

CT3IP Channel Interface Cards:

This command is used to configure the CT3IP and the 28 T1 channels. After the T1 channels are configured, continue to configure each T1 channel as a serial interface by using the interface serial global configuration command. Defaults: No T1, E1, or T3 controller is configured.


Example:

Cisco 7500 Series Router as a T1 Controller
The following example configures the MIP in slot 4, port 0 of a Cisco 7500 series router as a T1 controller:

Router(config)#controller t1 4/0
Router(config-controller)#

Cisco 4000 Series Router
The following example configures NIM 0 of a Cisco 4000 series router as a T1 controller:

Router(config)#controller t1 0
Router(config-controller)#

Cisco AS5800 Access Server with Dial Shelf
The following example configures the T1 controller in shelf 1, slot 0, port 0:

Router(config)#controller t1 1/0/0
Router(config-controller)#

Cisco 7500 Series
The following example configures the CT3IP in slot 3:

Router(config)# controller t3 3/0/0
Router(config-controller)#

Cisco AS5800 Access Server
The following example shows the status of the T1 controllers connected to the Cisco AS5800:
