Scope This document provides information on how to configure the SpeedTouch™ when
trying to set up end-to-end connectivity with a Broadband Remote Access Server
(BRAS). The aim of this configuration guide is to provide the essential information,
so that non DSL experts can make the more advanced SpeedTouch™
configurations.
Applicability This configuration guide is applicable to SpeedTouch™ Release R5.4 and higher.
History Since the first introduction of the SpeedTouch™ DSL modems (the A1000 ADSL
NT), the way data is passed back and forth between a computer or local LAN and
the Internet Service Provider (ISP) broadband access machines has changed
considerably. Starting from a plug and play IEEE 802.1D Transparent Bridge, DSL
devices rapidly evolved to DSL Home gateways and IP routers with NAT/NAPT
support for sharing a single public IP address with embedded firewalling techniques
as a countermeasure to attacks from the Internet.
Overview This chapter starts with some definitions and terminologies and then briefly
describes the different interfaces of the SpeedTouch™ and how to configure them.
