1 Introduction to this Guide
This guide is intended to provide the reader with an overview of the EDA
system and concept. The guide describes the different elements forming an
EDA network, and how they interact in order to constitute a versatile and
flexible ADSL access network.
The guide may be read without prior knowledge of EDA and the
technologies used, but to fully understand the system function the reader
should be familiar with the basics of IP (Internet Protocol) technology.
The guide can be printed on a monochrome printer, but illustrations are
easier to understand if a color printer is used.
