Chapter 18 Configuring MLPPP Backhaul
Configuring T1 Controllers
Use the following steps 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
encapsulation, and enabling keepalive packets. You might also need to enter other configuration
commands, depending on the requirements for your system configuration and the protocols you plan to
route on the interface.
Step 8
Router(config-controller)#
channel-group channel-no timeslots
timeslot-list speed {64}
Example:
Router(config-controller)#
channel-group 0 timeslots 1-31
speed 64
Specifies the channel-group and time slots to be mapped. After you
configure a channel-group, the serial interface is automatically created.
The syntax is:
• channel-no—ID number to identify the channel group. The valid
range is from 0–30.
• timeslot-list—Timeslots (DS0s) to include in this channel-group. The
valid time slots are from 1–31.
• speed {64}—The speed of the DS0.
The example configures the channel-group and time slots for the E1
controller:
Note When you are using the channel-group channel-no timeslots
timeslot-list {64} command to change the configuration of an
installed card, you must enter the no channel-group channel-no
timeslots timeslot-list speed {64} command first. Then enter the
channel-group channel-no timeslots timeslot-list {64} command
for the new configuration information.
Step 9
Router(config-controller)# exit
Router(config)#
Exits controller configuration mode.
Step 10
interface serial slot/port:channel
Example:
Router(config)# interface serial
0/0:1
Router(config-if)#
Configures the serial interface. Specify the E1 slot, port number, and
channel-group.
When the prompt changes to
Router(config-if), you have entered
interface configuration mode.
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 11
Router(config-if)# encapsulation
ppp
Specifies PPP encapsulation on the interface.
Step 12
keepalive [period [retries]]
Example:
Router(config-if)# keepalive
[period [retries]]
Enables keepalive packets on the interface and specify the number of
times keepalive packets are sent without a response before the router
disables the interface.
Step 13
Router(config-if)# end
Router#
Exits interface configuration mode.
