Chapter 1: Introduction
Welcome
Chapter1:Introduction
Welcome
Thank you for choosing the Phone Adapter with Router. This Phone Adapter will allow your computers to share a
high-speed Internet connection as well as resources, including files and printers. And after you have set up your
Internet phone service, also known as Voice over Internet Protocol (VoIP), you will be able to make phone or fax
calls using the Internet.
How does the Phone Adapter do all of this? By connecting your computers and peripherals, including phones or
fax machines, to the Phone Adapter and connecting the Phone Adapter to your cable or DSL modem, then the
Phone Adapter can direct and control communications for your network. Each of the Phone Adapter’s two
telephone jacks can operate independently, with separate phone service and phone numbers, so you can have
up to two Internet phone lines per Adapter.
But what does all of this mean?
Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share
Internet access, so you don’t need more than one high-speed Internet connection. With Internet phone service,
your Internet access can now be shared by your phones or fax machines as well. You will be able to make phone
calls using the account you set up with your Internet Telephony Service Provider (ITSP), even while you’re surfing
the Internet. Plus, you can access one printer from different computers and access data located on another
computer’s hard drive. Networks are even used for playing multiplayer video games. So, networks not only are
useful in homes and offices, but also can be fun.
PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.
ethernet: an IEEE standard network
protocol that specifies how data is
placed on and retrieved from a common
transmission medium.
lan (local area network): the computers
and networking products that make up
the network in your home or office.
network: a series of computers or
devices connected for the purpose of data
sharing, storage, and/or transmission
between users.

Chapter 2: Networking Basics
An Introduction to Local Area Networks
Chapter2:NetworkingBasics
An Introduction to Local Area Networks
Simply put, a router is a network device that connects two networks together.
The Phone Adapter connects your local area network (LAN), or the group of PCs in your home or office, to the
Internet. The Phone Adapter processes and regulates the data that travels between these two networks.
The Phone Adapter’s Network Address Translation (NAT) technology protects your network of PCs so users on the
Internet cannot “see” your PCs. This is how your LAN remains private. The Phone Adapter protects your network
by inspecting the first packet coming in through the Internet port before delivery to the final destination on one of
the Ethernet ports. The Phone Adapter inspects Internet port services like the web server, ftp server, or other
Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.
The Use of IP Addresses
IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers,
requires an IP address to identify its location, or address, on the network. This applies to both the Internet and
LAN connections.
There are two ways of assigning IP addresses to your network devices.
A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a
static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will
always have that same IP address until you change it. Static IP addresses are commonly used with network
devices such as server PCs or print servers.
static ip address: a fixed address
assigned to a computer or device that is
connected to a network.
nat (network address translation): NAT
technology translates IP addresses of a
local area network to a different IP
address for the Internet.
ip (internet protocol): a protocol used to
send data over a network.
ip address: the address used to identify a
computer or device on a network.

6Chapter 2: Networking Basics
The Use of IP Addresses
If you use the Phone Adapter to share your cable or 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
Phone Adapter. You can get the information from your ISP.
A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called
dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they
expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired,
the DHCP server will assign it a new dynamic IP address.
A DHCP server can either be a designated PC on the network or another network device, such as the Phone
Adapter. By default, the Phone Adapter’s Internet Connection Type is DHCP (obtain an IP address automatically).
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 Phone Adapter 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 Phone Adapter. 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
Phone Adapter, see the Router - LAN Setup section in “Chapter 5: Using the Web-based Utility.”
dynamic ip address: a temporary IP
address assigned by a DHCP server.
dhcp (dynamic host configuration
protocol): a protocol that lets one device
on a local network, known as a DHCP
server, assign temporary IP addresses to
the other network devices, typically
computers.

The Front Panel
The Phone Adapter’s LEDs, which inform you about network activities, are located on the front panel.
Power Green. The Power LED lights up when the Phone Adapter is powered on and connected to
the Internet. It flashes when the Phone Adapter is not connected to the Internet. The LED
also flashes when the Phone Adapter is booting up or upgrading its firmware.
INTERNET Green. The INTERNET LED lights up when there is an active connection through the port. If
the LED is flashing, then there is traffic moving through that port.
PHONE 1/2 Green. The PHONE LED is solidly lit when a telephone or fax machine has an active or
registered connection to your Internet Telephony Service Provider (ITSP) through the
corresponding port. It flashes when the phone is being used or is off the hook.
