Steps
Introduction
This chapter describes how to configure the AI2524 for fractional T1.
Configure
Fractional T1
Configuration Overview
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.
