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.
1.2 Hardware Configuration
This section introduces the appearance and structure of the
HG520s.

of a computer or a LAN hub.
RESET
To make the equipment restored and restarted, press
the RESET button and release it within 3 seconds. To
make the equipment restore the default settings of the
HG520s, press the RESET button and release it after 3
seconds. Once you use this function, all your
customized settings will be lost. Therefore, please be
careful with it.
POWER Connect to the power adapter.
ON/OFF Switch on/off HG520s.
1.2.3 Splitter
The external splitter can efficiently reduce the signal disturbance
on the telephone line. When voice and data are transmitted through the
same telephone line at the same time, you need an external splitter to
separate the voice and data signals:
 LINE: Connecting to the phone jack on the wall.
 PHONE: Connecting to the telephone.
 MODEM: Connecting to the ADSL interface of the HG520s.
