Choosing a place for the ADSL Router

1.

Place the ADSL Router close to ADSL wall outlet and power outlet for the cable to reach it easily.

2.

Avoid placing the device in places where people may walk on the cables. Also keep it away from direct

sunshine or heat sources.

3.

Place the device on a flat and stable stand.

Connecting the ADSL Router

Follow the steps below to connect the related devices.

1.

Remove the end of the phone line from your phone connector and plug it onto the “LINE” port of the POTS

Splitter. Use another phone line to connect your phone and splitter. Plug this phone line onto the “PHONE” port

of the ADSL splitter, and plug the other end of the line onto your phone.

2.

Use the line to connect the ADSL splitter (MODEM port) and router’s DSL port.

3.

Please attach one end of the Ethernet cable with RJ-45 connector to the

LAN

port of your ADSL Router.

4.

Connect the other end of the cable to the Ethernet port of the client PC.

5.

If you want to connect to a hub for used by many devices, please connect the other end to the uplink port of the

hub.

6.

Connect the supplied power adapter to the

PWR

port of your ADSL Router, and plug the other end to a power

outlet.

7.

Turn on the power switch.

Note:

For Full Rate (G.dmt) standard, a POTS Splitter is necessary on subscriber’s premise to keep

the telephone and ADSL signals separated, giving them the capability to provide

simultaneous Internet access and telephone service on the same line. To connect a POTS

Splitter:

1. Connect the port

Phone

to your telephone.

2. Connect the port

Modem

to your ADSL Router.

3. Connect the port

Line

to the ADSL wall jack.

Chapter 3: Connection Mode

Prior to configuring the ADSL Router, you must decide whether to configure the ADSL Router as a bridge or as a

router. This chapter presents some deployment examples for your reference. Each mode includes its general configure

procedures. For more detailed information about web configuration, refer to "Web Configuration".

For making sure that you can connect the ADSL to your computer well and get into Internet successfully, please

make sure the following first.

1. Make sure you have installed a network interface card onto your computer.

2. Make sure the connection between the ADSL and your computer is OK.

3. Check to see the TCP/IP protocol and set the IP address as “Auto Get IP Address”.

When you are sure all above is Ok, you can open the Browser and type in “192.168.100.100” and start to do the web

configuration with different connection modes.

This chapter is going to introduce the function of each connection mode and tell you the basic configuring steps that

you have to do. If you did not follow the configuring steps for using these connection modes, you might get some

connection problems and cannot connect to Internet well.

Description:

In this example, the ADSL Router acts as a bridge which bridging PC IP address from LAN to WAN. PC IP address

can be a static public address that is pre-assigned by ISP or a dynamic public address that is assigned by ISP DHCP

server, or can be got from PPPoE software.

Therefore, it does not require a public IP address. It only has a default private IP address (192.168.100.100) for

management purpose.

Configuration:

1.

Choose a client PC and set the IP as 192.168.100.x (x is between 2 and 254) and the gateway as

192.168.100.100.

2.

Start up your browser and type

192.168.100.100

as the address to enter the web-based manager.

Description:

In this deployment environment, we make up a private IP network of 192.168.100.100. NAT function is enabled (on

ADSL Router or use another NAT box connected to hub) to support multiple clients to access the Router and some

public servers (WWW, FTP).

If you apply for multiple IP addresses from your ISP, you can assign these public IP addresses to the ADSL Router

and public server, e.g., Web or FTP server. Typically the first IP is network address, the second is used as router IP

address and the last one is subnet broadcasting. Other remaining IP addresses can be assigned to PCs on the LAN.

For example: You are given the IP addresses 10.251.2.0 ~ 10.251.2.7. Then:

10.251.2.0 is network IP address

10.251.2.1 is assigned to router IP address.

10.251.2.7 is subnet broadcasting

10.251.2.2~10.251.2.6 can be assigned to public servers on the LAN.

Configuration:

1.

Start up your browser and type

192.168.100.100

as the address to enter this ADSL web-based manager.

2.

Go to
