Overview

ATM Access Modules

There are two M-ACC OC-12 ATM Access modules for the Avaya M770

Multifunction switch:

•	M-ACCF:	500m, Multimode fiber, can also be OC-3 reduced range
•	M-ACCSF:	15 km, Single-mode fiber, can also be OC-3

The M-ACC ATM Access modules need the following S/W Versions:

•M-ACCF/SF ATM Entity S/W Version 1.8

•M-ACCF/SF X-Switch Module S/W Ver. 4.0.7

•M-SPX/M-SPS Embedded S/W 3.2.1 and higher.

Features and Benefits

This Section describes the main features of the M-ACC OC-12 module and the benefits of ATM within your network. The following topics are described:

•ATM Benefits

•ATM Access Module Features

The ATM module provides a high-speed ATM connection between your Avaya M770 X-Switch domain and the ATM network.

Positioned within a workgroup or departmental LAN, the ATM access module provides a fast ATM uplink to the building or ATM campus.

Redundant links protect your Switch from network and equipment failure, while the software upgrade feature future-proofs your Switch by allowing you to add new features as they become available.

ATM Benefits

ATM is the only technology specifically designed to carry voice, video and data traffic simultaneously and to provide the required level of service that these different applications need in order to run effectively across a network. ATM provides the following benefits:

•It is easy and of low cost to add additional services to the ATM network.

•Services can be added as and when they are needed. It is easier to scale ATM networks compared to other network technologies.

•ATM devices interoperate with your existing network. LAN Emulation (LANE) is a standards-based technology specifically designed to provide interoperability between existing Ethernet/Fast Ethernet networks and ATM
