Configuring E1 Interfaces
Use the following procedure to configure a new E1 or CE1/PRI interface
(balanced or unbalanced) or to change the configuration of an existing interface.
Step 1 Identify the port number and enter line-specific information provided by your
local carrier.
a. Select the CE1/PRI interface to configure by entering the following command
from global configuration mode. This example configures an E1 interface in
slot 1 and unit 0.
c4224(config)# controller e1 1/0
b. Specify the framing type.
c4224(config-controller)# framing crc4
c. Specify the line code format.
c4224(config-controller)# linecode hdb3
Step 2 Configure parameters for the voice interface.
a. Specify the PRI group and time slots to be mapped.
c4224(config-controller)# pri-group timeslots 1-31
