Chapter 2: Networking Basics

The Use of IP Addresses

Broadband Router with 2 Phone Ports

A DHCP server can either be a designated PC on the network or another network device, such as the Router. By

default, the Router’s Internet Connection Type is

Obtain an IP automatically

(DHCP).

The PC 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.

For DSL users, many ISPs may require you to log on with a user name and password to gain access to the

Internet. This is a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE).

PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a

connection. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.

By default, a DHCP server (on the LAN side) is enabled on the Router. 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 Router,

see the Basic Setup section in “Chapter 5: Configuring the Router.”

The Back Panel

The Router’s ports and the Reset button are located on the back panel of the Router.

Internet

This

Internet

port connects to your cable or DSL modem.

Phone1

For your primary Internet phone line, the

Phone1

port allows you to connect the Router to your

telephone (or fax machine) using an RJ-11 telephone cable (not included).

Phone2

If you have a second Internet phone line, the

Phone2

port allows you to connect the Router to

your second telephone (or fax machine) using an RJ-11 telephone cable (not included).

Ethernet 1-4

These four

Ethernet

ports connect to network devices, such as PCs, print servers, or

additional switches.

Reset Button

There are two ways to reset the Router to its factory default settings. Either press the

Reset

button for approximately five seconds, or restore the defaults from the Administration tab -

Factory Defaults of the Router's Web-based Utility.

Power

The

Power

port is where you will connect the power adapter.

Figure 3-1: Back Panel

IMPORTANT:

If you reset the Router, all of

your settings, including Internet connection,

Internet phone service, and security settings,

will be deleted and replaced with the factory

defaults. Do not reset the Router if you want to

retain these settings.

(If you have an active Internet phone service

account and reset the Router, then the Router

will automatically download its Internet phone

service settings once it is connected to the

Internet again.)

The Front Panel

Broadband Router with 2 Phone Ports

The Front Panel

The Router’s LEDs, which inform you about network activities, are located on the front panel.

Power

Green. The

Power

LED lights up when the Router is powered on. If the LED is flashing, the

Router is booting up or running a system self-test.

Ethernet 1-4

Green. The

Ethernet

LED serves two purposes. If the LED is solidly lit, the Router is connected

to a device through the corresponding port (Ethernet 1, 2, 3, or 4). If the LED is flashing, the

Router is sending or receiving data over that port.

Phone 1-2

Green. The

Phone

LED is solidly lit when a telephone or fax machine has a registered

connection to AT&T through the corresponding port (Phone 1 or Phone 2). (The connection is

registered if your Internet phone service account is active.) This LED is not lit when there is no

registered connection. It flashes when the phone is being used or an incoming call has been

detected.

Internet

Green. The

Internet

LED lights up when the Router is connected to your cable or DSL modem.

If the LED is flashing, the Router is sending or receiving data over the Internet port.

Overview

Broadband Router with 2 Phone Ports

Chapter 4: Connecting the Router

Overview

This chapter includes two sets of instructions. If the Broadband Router with 2 Phone Ports will be the only router

in your network, follow the instructions in “Connecting the Router to Your Broadband Modem.” If you already have

a router in your network and want to add the Broadband Router with 2 Phone Ports, follow the instructions in

“Connecting One Router to Another.”

Connecting the Router to Your Broadband Modem

1.

Make sure that all of your hardware is powered off, including the Router, PCs, and broadband modem.

2.

Connect your broadband modem’s Ethernet cable to the Router’s Internet port.

3.

Plug a standard telephone into the Router’s Phone1 port.

4.

Connect one end of an Ethernet network cable to one of the numbered ports on the back of the Router.

Connect the other end to an Ethernet port on a network device, e.g., a PC, print server, or switch.

Repeat this step to connect more PCs or other network devices to the Router.

5.

Power on the broadband modem.

6.

Connect the included power adapter to the Router’s Power port, and then plug the power adapter into an

electrical outlet. The Power LED on the front panel will light up as soon as the Router powers on.

7.

Power on your PC(s).

Proceed to “Chapter 5: Configuring the Router.”

NOTE:

Make sure your telephone is set to its tone setting (not pulse).

IMPORTANT:

Do not connect the Phone port to a telephone wall jack. Make sure you only connect

a telephone or fax machine to the Phone port. Otherwise, the Router or the telephone wiring in your

home or office may be damaged.

Connecting One Router to Another

If you already have a router (for example, a wireless router) and want to add the Broadband Router with 2 Phone

Ports, then you should use the Broadband Router with 2 Phone Ports as your primary router so the Internet phone

calls will be routed properly. For example, the following connection diagram shows the Broadband Router with

2 Phone Ports connected to a wireless router, phone, and desktop PCs.
