Atm | 3Com 6416SW specification

Chapter 1. Introduction to

ATM

This chapter presents an overview of the				main principles and modes of operation of
asynchronous transfer mode (ATM) technology on which the 3Com ONcore ATM
Switch/Control		(6416SW) module is based. It		also describes how ATM is implemented
in the	3Com	ONcore	Switching Hub and shows	how an ONcore-based ATM campus
network	can	be built	by interconnecting ATM	subsystems.
