Configuring the Cisco 2524 and Cisco 2525 Routers 4-19
Configuring the Router
Take the following steps to configure the fractional T1/T1 DSU/CSU WAN module for a
typical leased-line connection, substituting the correct addresses and host names as
appropriate for your network:
Step 1
Enter enable mode:
Router> enable
password:
enablepassword
Step 2
Enter configuration mode:
Router# config term
Router(config)#
Step 3
Assign an IP address to the serial port on the module:
Router(config)# interface serial
port_number
Router(config-if)# ip address
ipaddress subnetmask
Router(config-if)# no keepalive
Step 4
Enter the framing type and line code type, substituting framing_type with sf
(Superframe) or esf (Extended Superframe) and linecode_type with ami (alternate
mark inversion) or b8zs (bipolar eight zero substitution):
Router(config-if)# service-module t1 framing
framing_type
Router(config-if)# service-module t1 linecode
linecode_type
Step 5
If you are using fractional T1 service, enter the time slot range and speed. In the
following example, the time slot range is from 1 to 20 and the speed is 64-kbps:
Router(config-if)# service-module t1 timeslots 1-20 speed 64
Step 6
Return to user EXEC mode:
Router(config-if)# exit
Router(config)# exit
Router# exit
