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:
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
