SOHO

Smart Gateway DSL Router

Overview

Digital subscriber line (DSL) is the world's
most prevalent broadband technology for
residential and SOHO subscribers.
According to the DSL Forum, approximately
36 million DSL lines are now installed
worldwide. DSL will continue to gain
momentum as subscribers demand higher
bandwidth and multiservice access (voice/
video/data).

Customer premises equipment (CPE)
manufacturers have responded to the
steady growth of the DSL market by
developing new generations of routers that
enable subscribers to connect a variety of
computing and peripheral devices, such as
desktop PCs, laptops, PDAs, printers and
servers.

Design Challenges

Time-to-market and system cost are key
considerations in designing DSL router
products. Design cycles for routers are
relatively short, which is typical for
consumer electronics products. System
developers often must speed consumer
premises equipment (CPE) products to
market in a matter of months to achieve
revenue goals. Developing complex
designs from scratch and having to work
with multiple hardware and software
vendors not only impacts time-to-market,
but it can also increase development
costs. System integration involving

PROTOCOL STACKS FOR DSL ROUTER WITH OPTIONAL VPN

operating systems, communication
software stacks, and board support
packages (BSPs) also contribute to the
burgeoning cost of creating new router
applications. Increasing competition
requires the timely delivery of DSL
products to the router marketplace.

Freescale Semiconductor Solution

The solution is DSL router software from
Metrowerks, a Freescale Semiconductor
company. When combined with a
Freescale Semiconductor Smart
Gateway reference platform,
Metrowerks' DSL router software
provides a complete Linux® OS-based

HTML UI for End User and

Programmer APIs for Application Developer

solution that enables developers to
speed their router products to market.

DSL Router software is a production­ready development environment for
designers and manufacturers of DSL
router equipment. It provides a complete
set of protocol stacks for DSL CPE
devices, including support for optional
virtual private network (VPN) capability.
Metrowerks' DSL router software
leverages the scalability of Linux, is
based on interoperable open standards,
and includes an easy-to-use HTML
interface for router configuration and
administration.
