Introduction

Chapter 1 Introduction

1.1 Overview

This xDSL Router features two broadband technologies such as ADSL and
SHDSL. Multi-mode ADSL technology that provides a downstream rate of
up to 8Mbps over existing copper wire lines, which is more than 100 times
faster than a traditional 56K analog modem.
SHDSL technology that provides a symmetric upstream and downstream
rate of up to 2.3Mbps over existing copper wire lines.

And it can be connected to your PC or LAN through the 10 B ase-T or
100Base-T Ethernet interface.

This xDSL Router is designed to meet both the needs of single user, and
multiple users at small offi ce a nd home of fice who wa nt f ast Inter net a cce ss.
A wide variety of features and interoperabilit y offer scalability and
flexibility for all the applications

Introduction

1.4 Important Rules for Safe Operation

In addition to the careful attention devoted to quality standards on the
manufacture of your ADSL Router, safety is a major factor in the design of
every product. However, safety is your responsibility, too. This section lists
important information that will help assure your enjoyment and proper use
of the ADSL Router and accessory equipment. Please read them carefully
before operation and usi ng your Router.

! Read and Follow Instructions – you should read all the safety and

operating instructions before operating the Router.

! Retain Instructions – You should save all the safety and operating

instructions, for your future reference.

! Heed Warning – Comply with all warnings on the products and in

the operating instructions.

! Check Power Sources – Operate this product only from the type of

power source indicated on the product’s marking label. If you

Overloaded AC outlets, extension cords, frayed power cords,
damaged or cracked wire insulation, and br oken plugs are
dangerous. They may result in a shock or fire hazard.
Periodically examine the cord, and if its appearance indicates
damage or deteriorated insulation, have it replaced by your
service technician.

! Protect Power Cords – Route power supply cords so that they are

not likely to be walked on or pinched by items placed u p on or
against them. Pay particular attention to cords where they are
attached to plugs and convenience receptacles, and examine the
point where they exit from the product.

! Check Ventilation – Slots and openings in the enclosure are

provided for ventilation to ensure reliable operation of the
product and to protect it from overheating. Do not block or cover
these openings. Never block these openings by pla c ing the
product on a bed, sofa, rug, or other similar surface. Never place
this product near or over a radiator or heat re giste r, or any other

Configuring your xDSL
Router

The major functions of the xDSL Router are performed by using Ethernet
10Base-T or 10/100Base-T network interface. Your computer has to install
an Ethernet NIC card and set up the TCP/IP protocol before start to using
the xDSL Router.

The xDSL Router also provides a serial console port for monitoring and
configuring the Router via the xDSL Configurat ion Tool or HyperTerminal
program.

2.2 Hardware Installation

Before start to configure your Router, you have to complete all the
hardware installation. The followi ng steps provide instructions for
installing your Router.

1. Be sure the power switch on the right side of the Router is at the

OFF status.

2. Connect the power adaptor to the power jack that marked Power

at the rear panel of the Router, then plug in the DC power
adaptor to the wall electrical outlet.

3. Connect the Ethernet cable.

A) If connect to computer directly

Connect one end of Ethernet straight-through cable to the
Ethernet port on your computer, then connec t the other
end of Ethernet straight-though cable to the connector that
marked 10/100Base-T at the rear panel of the Router.

B) If connect to more than one computer via Hub Connect one

end of Ethernet straight- through cable (If your up-li nk hub
without cascade switch, please use an Ethernet crossover
cable instead) to the uplink port on the Ethernet Hub, then
connect the other end of Ethernet cable to the connector that
marked 10/100Base-T at the rear panel of the Router.

4. Connect one end of RJ11 telephone cable to the xDSL line jack

that marked xDSL at the rear panel of the Router, then connect
the other end of RJ-11 telephone cable to the xDSL service port
that your xDSL service provider or ISP installed.

5. Connect the male (9 pin) end of the RS-232 serial cable to the

connector that marked Console port at the rear panel of the
Router, then plug the other end of the RS-232 serial cable to the
RS-232 serial port of your computer.

6. Turn on the power switch. The Router should perform a self-test,

and then be ready for use.

2.3 Windows 95/98 setting for Ethernet LAN

connection

Either connect to Internet or configure the Router via Ethernet, the TCP/IP
protocol is really necessa r y. And your computer must be on the same
subnet with the Router.

When you directly connect the Router to your computer through the
Ethernet network, you will first configure your computer to obtain an IP

address automatically from your Router’s DHCP server, or specify an IP
address and Subnet Mask to the same subnet as remote host. The

following steps provides the instructions to setup your computer to obtain
an IP address by using Windows 95/98 on a PC

2.3.1 Check TCP/IP protocol

To check if TCP/IP is properly installed, please procee d to the following
steps.

1. Double-click on My computer->Control Panel->Network

2.4 Configuring the Router

There is some setup required to get your xDSL Router working properly.
The configuration of the xDSL Router can be a c c essed in three ways:

# Using TELNET via Ethernet interface
# Using terminal pr ogram via serial console port
# Using xDSL C onfiguration Tool (ACT ) via serial console port

2.4.1 Using TELNET via Ethernet interface

To access the command line interface via Ethernet interface, you can use
TELNET to log in the Router from the local Ethernet network using the
Ethernet IP address that assigned to your xDSL Router. The Ethernet IP of
the xDSL Router is default set to 192.168.7.1.

1. Select Start->Programs->MS-DOS Prompt.

2. Find the IP address of the Router’s Ethernet port. Then use

TELNET to login the Router. For example, TELNET

192.168.7.1

3. You will see that a telnet dialog pop s up a sking for password

(case sensitive), then enter admin ↵

5. Now you are ready to configure the Router by using command.

Please contact your ISP/NSP to obtain the detail command sets of
your Router. If the Router does not return any message, refer to
Appendix B for troubleshooting information.

2.4.2 Using terminal program via serial console port

A terminal can be connected directly to the Ser ial console port. This
requires the use of a terminal emulation software package such as
Microsoft HyperTerminal. By default setting, the Rout er is conf igured to
communicate at a baud rate of 9600. Any standard terminal that support
baud rate of 9600 can be connected to the Router’s console port. Please
configure your serial port as:
BPS : 9600
Data bits : 8
Parity : None
Stop Bits : 1
Flow Control : None

Following steps provide the instructions to log on to the Router via
Microsoft HyperTermi nal.
