HDLC CONFIGURATION STEPS
This section lists the commands for HDLC configuration.
Note: The following HDLC configuration commands are shown for a T1 interface as an 
example. The steps are similar for configuration of HDLC on an E1 interface.
Step 1: Enter Configuration Mode
ALU# configure terminal
ALU(config)#
Step 2: Set the controller mode to T1
ALU(config)# card type T1 <slot>
ALU(config)#
Step 3: Configure T1 controller
ALU(config)# controller T1 <slot/port>
ALU(config-controller T1)#
Step 4: Configure the channel-group on the controller before entering the 
Interface Configuration Mode. This command creates a channel-group that forms 
a channelized serial interface.
ALU(config-controller T1)# channel-group <0-23> 
timeslots <1-24> speed [56K|64K]
Note: Creation of a channel-group is a pre-requisite for configuring a Serial interface on a T1 
or an E1 controller.
Step 5: Administratively bring up the controller
ALU(config-controller T1)# no shutdown
Step 6: Exit from the controller mode
ALU(config-controller T1)# exit
ALU(config)#
Note: The above steps can be skipped if the T1 or E1 controller has already been 
configured. For more details on configuring a T1 or an E1 controller, refer to the “T1E1 
Line Card” chapter.
The above steps can also be skipped if you are configuring HDLC on a Serial 
interface (V.35/X.21). The steps (Step 6 - Step 12) hold good for configuration of 
HDLC on a V.35/X.21 interface, except that there is no channel group number in the 
interface name. Configure serial interface using the following command:
