Chapter 1 Introduction
This chapter introduces functions and structure of the EchoLife
HG520s Home Gateway (hereinafter referred to as the HG520s).
1.1 Functions and Features
The HG520s is a type of Asymmetric Digital Subscriber Line
(ADSL) terminal. Data, video and audio are transmitted through the
common telephone line at a higher rate by the HG520s.
The features of the HG520s are:
 High transmission rate: The maximum downstream transfer
rate is 24 Mbit/s; the maximum upstream transfer rate is
1.2 Mbit/s.
 Strong network adaptability: The HG520s can be
interconnected with multiple Digital Subscriber Line Access
Multiplexes (DSLAMs).
 Strong maintainability: The HG520s provides multiple
indicator status, which is convenient to locate failures.
 Easy operation: The HG520s has a simple operation for the
configuration and management page.
