Chapter 16: Basic Configuration

Configuring the

Fractional T1/T1

DSU/CSU WAN

Module

This section describes how to configure the fractional Tl/T1 DSU/ CSU WAN module is configured for Extended Superframe Format (ESF) signal format, bipolar zero substitution (B8ZS), and full band- width as the factory default. Depending on networking environment, you might need to change these settings.

Take these steps to configure the fractional Tl/T1 DSU/CSU WAN module for a typical leased-line connection, substituting the correct addresses and host names as appropriate for your network:

1. Enter enable mode:

Router> enable password: enablepassword

2. Enter configuration mode:

Router# config term

Router(config)#

3. Assign an IP address to the serial port on the module:

Router(config)# interface serial port_number

Router(config-if)# ip address ipaddress suLnetmask

Router(config-if)# no keepalive

4.Enter the framing type and line code type, substituting framing_type with sf (Superframe) o esf (Extended Super frame) and linecode_type with ami (alternate mark inversion) o b8zs (bipolar eight zero substitution):

Router(config-if)# service-module tl framing framing_type

Router(config-if)# service-module tl linecode linecode type

5.If you are using fractional T1 service, enter the time slot range and speed. In this example, the time slot range is from 1 to 20 and the speed is 64-kbps:

Router(config.f)# service-module tl timeslots 1-20 speed 64
