Chapter 14: T1 Interface Configuration Steps

Introduction

This chapter describes how to configure the AI2524 for fractional T1.

Configuration Overview

Fractional T1

This section describes how to configure fractional T1 and T1 (FT1/T1

 

 

service modules installed the AI2425 router. The tasks associated with

 

configuring T1 include:

 

z Specify the Clock Source

 

z Enable Data Inversion Before Transmission

 

z Specify the Frame Type of a FT/T1 Line

 

z Specify the CSU Line Build Out

 

z Specify FT1/T1 Line-Code Type

 

z

Enable Remote Alarms

 

z Enable Loopcodes that Initiate Remote Loopbacks

 

z

Specify Timeslots

Specify the Clock Source

To specify the clock source for the FT1/T1 CSU/DSU internal clock or the line clock, type this in interface configuration mode:

service-module t1 clock source {internal line}

Enable Data Inversion Before Transmission

Data inversion is used to guarantee the T1s density requirement on an

AMI line when using bit-oriented protocols such as High-Level Data

Link Control (HDLC), Point-to-Point Protocol (PPP), X.25, and

Frame Relay.
