Avaya M770 Introduction

Avaya M770 ATM Switch User’s Guide 1

Introduction

This chapter provides information about the Avaya M770 ATM Switch, and the

features that this software release supports.

Note: This User Guide describes only the ATM functionality of the Avaya M770 chassis.

The M770 ATM switch is a high-performance distributed Asynchronous Transfer

Mode (ATM) switch that is designed for building and campus backbone

applications, high-performance centralized servers, and power-user environments.

Its advanced architecture can support very high traffic loads with no data loss or

breaks in communication. The M770 ATM Switch also implements LAN Emulation

(LANE) components. LANE enables legacy LAN applications to use a transparent

ATM transport medium. In this way, end-stations on existing LANs can

communicate with ATM end-stations.

The M770 ATM Switch supports a range of option modules that enable you to

customize the switch to fulfil applications that are appropriate to your networking

requirements. It is designed as a software-upgradeable product. Therefore, you can

expand the functionality of the switch by downloading new software.
