Chapter 2: Planning Your Network

IP Addresses

ADSL Gateway

Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have

assigned a static IP address to your account. If so, you will need that static IP address when configuring the

Gateway. You can get that information from your ISP.

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.

These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device.

After a certain time period, they expire and may change. If a computer logs onto the network (or the Internet) and

its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP

server. The computer or network device obtaining an IP address is called the DHCP client. DHCP frees you from

having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated computer on the network or another network device, such as the

Gateway. By default, the Gateway’s DHCP Server function is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you

run more than one DHCP server on your network, you will experience network errors, such as conflicting IP

addresses. To disable DHCP on the Gateway, see the DHCP section in “Chapter 5: Configuring the ADSL Gateway.”

Ethernet (1-4)

The

Ethernet

ports connect to your computers and other network devices.

Reset Button

There are two ways to reset the Gateway's factory defaults. Either press the

, for

approximately ten seconds, or restore the defaults from the

Administration

tab in the Gateway’s Web-based Utility.

Power

The

Power

port is where you will connect the power adapter.

IMPORTANT:

Resetting the Gateway to factory

defaults will erase all of your settings

(including Internet connection and other

settings) and replace them with the factory

defaults. Do not reset the Gateway if you want

to retain these settings.

POWER

Green. The

POWER

LED lights up when the Gateway is powered on.

ETHERNET (1-4)

Green. The

LED serves two purposes. If the LED is continuously lit, the Gateway is

successfully connected to a device through the LAN port. If the LED is flashing, it is an

indication of any network activity.

DSL

Green. The

DSL

LED lights up whenever there is a successful DSL connection. The LED blinks

while the Gateway is establishing the ADSL connection.

INTERNET

Green. The

INTERNET

LED lights up green when an Internet connection to the Internet Service

Provider (ISP) is established. The

INTERNET

LED lights up red when the connection to the ISP

fails.

The Bottom Panel

The Gateway has a built-in stand available. If you place the Gateway flat on a surface, then you can leave the

stand in the closed position. However, if you want the Gateway to be upright, swivel the stand clockwise 90º and

position the Gateway accordingly.

Chapter 4: Connecting the ADSL Gateway

Overview

ADSL Gateway

Chapter 4: Connecting the ADSL Gateway

Overview

The installation technician from your ISP should have left the setup information for the modem with you after

installing your broadband connection. If not, you can call your ISP to request that data.

After you have the setup information you need for your specific type of Internet connection, you can begin

installation and setup of the Gateway. Continue to “Connecting the Gateway to a Computer.”

Connecting the Gateway to a Computer

1.

Make sure that all of your network’s hardware is powered off, including the Gateway and all computers.

2.

Connect a phone cable from the Line port on the Gateway’s side panel to the wall jack of the ADSL line. A

small device called a microfilter (not included) may be necessary between each phone and wall jack to

prevent interference.

Contact your ISP if you have any questions.

Figure 4-1: Connect the ADSL Line

IMPORTANT:

For countries that have phone jacks with RJ-11 connectors, make sure to only place

the microfilters between the phone and the wall jack and

not

between the Gateway and the wall

jack or your ADSL will not connect.

For countries that do

not

have phone jacks with RJ-11 connectors (e.g. France, Sweden,

Switzerland, United Kingdom, etc.), except for ISDN users, the microfilter has to be used between

the Gateway and the wall jack, because the microfilter will have the RJ-11 connector. (Extra filters

may be required for phones at your location.)

Annex B users must use the included special cable to connect the Gateway to the wall jack

(Standard Annex B units have an RJ-45 to RJ-12 cable and Annex B with UR-2 support have a stand

network cable RJ -45 to RJ-45 cable).

If you require splitters or special jacks, please contact your

service provider.

NOTE:

A small device called a microfilter (not included) may be necessary between each phone

and wall jack to prevent interference.

Contact your ISP if you have any questions.
