Cisco Systems 3825 manual Configuring T1 Controllers, Exit the controller configuration mode

Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line

Configuration Sequence

Step 3 Specify the channel-group and time slots to be mapped. Once you configure a channel-group, the serial interface is automatically created.

Router(config-controller)#channel-group channel-notimeslots timeslot-listspeed {64}

Where:

•channel-no—ID number to identify the channel group. The valid range is 0 to 30.

•timeslot-list—Timeslots (DS0s) to include in this channel group. The valid timeslots are 1 to 31.

•speed {64}—The speed of the DS0: 64 kbps.

For example, the following command configures the channel-group and time slots for the E1 controller:

Router(config-controller)#channel-group 0 timeslots 1-31 speed 64

Note When you are using the channel-groupchannel-notimeslots timeslot-list{64} command to change the configuration of an installed card, you must enter the no channel-groupchannel-notimeslots timeslot-listspeed {64} command first. Then enter the channel-groupchannel-notimeslots timeslot-list{64} command for the new configuration information.

Step 4 Exit the controller configuration mode.

Router(config-controller)# exit

Step 5 Configure the serial interface. Specify the E1 slot, subslot, port number, and channel-group.

Router(config)# interface serial slot/subslot/port:channel

Router(config-if)#

Note To see a list of the configuration commands available to you, enter ? at the prompt or press the Help key while in the configuration mode.

Step 6 To configure PPP encapsulation, enter the following command:

Router(config-if)# encapsulation ppp

Step 7 Enable keepalive packets on the interface and specify the number of times keepalive packets will be sent without a response before bringing down the interface:

Router(config-if)# keepalive [period [retries]]

Step 8 Return to Step 1 to configure the second port on the Cisco 2-port T1/E1-RAN interface card and the ports on any additional Cisco 2-port T1/E1-RAN interface cards.

Step 9 Exit the interface configuration mode.

Router(config-if)# exit

Configuring T1 Controllers

Use the following instructions to perform a basic T1 controller configuration: specifying the T1 controller, specifying the framing type, specifying the line code form, specifying the channel-group and time slots to be mapped, configuring the cable length, configuring the serial interface, configuring PPP
