Getting to Know the ADSL Ethernet
Modem
Overview
Asymmetric Digital Subscriber Line (ADSL), the most popular residential
DSL technology, provides high-speed Internet access over regular, copper
phone lines by maximizing bandwidth use. In this way, ADSL Internet service
can coexist on the same line as your phone service, without disrupting calls.
ADSL is “asymmetric” because it downloads, or receives data, faster than it
uploads, or transmits data. Asymmetric operation is ideal for home and small
office use where f iles and information are downloaded more frequently than
uploaded.
Powe r The Powe r port is where you will connect the
power adapter.
Console This port is reserved for future development and is
currently of no use.
Line This port connects your modem to your ADSL
line.
LAN This LAN (Local Area Network) port connects to
your PC with the included network cable. You can
also connect network devices, such as a hubs and
switches with a straight-through RJ-45 cable or use
a cross-over RJ-45 cable to connect a router.

Troubleshooting
This section offers solutions to common issues that may occur during the
installation and operation of your ADSL Ethernet Modem.
1. Which protocols might I need to use with my ADSL Ethernet Modem?
• Refer to the documentation or manual provided b y your ISP for details. The
protocol required in your configuration depends on the equipment used by
your DSL service provider. There are several possibilities:
a. Point-to-Point Protocol Over ATM (PPPoA) (RFC 2364) - PPP pro-
vides session setup, user authentication (login), and encapsulation for
upper-layer protocols such as IP (Internet Protocol). The use of PPP
makes the modem appear as a dial modem to the operating system. DialUp Networking is used to establish a connection.
b. Bridged/Routed Ethernet/IP over ATM (RFC 1483) - This protocol
makes the modem appear as a local area network (LAN) device to the
operating system.
c. Point-to-Point Protocol Over Ethernet (PPPoE) (RFC 2516) - PPP
provides session setup, user authentication (login), and encapsulation for
upper-layer protocols such as IP (Internet Protocol). PPP makes the
modem appear as a dial modem to the operating system. Dial-Up
Networking is used to establish a connection. The protocol must be supported by a PPPoE client, such as WinPoet or EnterNET 300 logon software, on the RFC 1483 driver.
2. The ADSL Ethernet Modem can achieve an ADSL connection, but cannot
access the Internet.
• If network settings are assigned by the DHCP server, check whether the IP
address and Gateway IP address have actually been assigned by the DHCP
server.
• Try to ping the Gateway IP Address, then check the response from the
Gateway.
• If this fails, contact your ISP for more information.

Glossary
Adapter - Printed circuit board that plugs into a PC to add to capabilities or
connectivity to a PC. In a networked environment, a network interface card
(NIC) is the typical adapter that allows the PC or server to connect to the
Internet.
ADSL (Asymmetric Digital Subscriber Line) - A technology for transmitting
digital information at a high bandwidth on existing phone lines to homes and
businesses. Unlike regular dialup phone service, ADSL provides continuouslyavailable, "always on" connection. ADSL is asymmetric in that it uses most of
the channel to transmit downstream to the user and only a small part to receive
information from the user. ADSL simultaneousl y accommodates analo g (voice)
information on the same line. ADSL is generally offered at downstream data
rates from 144 Kbps to about 6 Mbps. A form of ADSL, known as Universal
ADSL or G.lite, has been approved as a standard by the ITU-TS.
ADSL was specifically designed to exploit the one-way nature of most multimedia communication in which large amounts of information flow toward the
user and only a small amount of interactive control information is returned.
Several experiments with ADSL to real users began in 1996. In 1998, widescale installations began in several parts of the U.S. In 2000 and beyond, ADSL
and other forms of DSL are expected to become generally available in urban
areas. With ADSL (and other forms of DSL), telephone companies are competing with cable companies and their cable modem services.
Bandwidth - The transmission capacity of a given facility, in terms of how
much data the facility can transmit in a fixed amount of time; expressed in bits
per second (bps).
Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.
Also, the smallest form of data.
Broadband - A data-transmission scheme in which multiple signals share the
bandwidth of a medium. This allows the transmission of voice, data and video
signals over a single medium. Cable television uses broadband techniques to
deliver dozens of channels over one cable.
CPU (Central Processing Unit) - The computing part of the computer. Also
called the "processor," it is made up of the control unit and ALU.

Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a wa y to distinguish the "box" and the electronic circuitry and components of a computer
from the program you put in it to make it do things. The program came to be
known as the software.
Hub - The device that serves as the central location for attaching wires from
workstations. Can be passive, where there is no amplification of the signals; or
active, where the hubs are used like repeaters to provide an extension of the
cable that connects to a workstation.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
describes itself as "the world's largest technical professional society -- promoting the development and application of electrotechnology and allied sciences
for the benefit of humanity, the advancement of the profession, and the wellbeing of our members."
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of jour nals, has
many local chapters, and several large societies in special areas, such as the
IEEE Computer Society.
IP Address - In the most widely installed level of the Internet Protocol
(Internet Protocol) today, an IP address is a 32-binary digit number that identifies each sender or receiver of information that is sent in packet across the
Internet. When you request an HTML page or send e-mail, the Internet
Protocol part of TCP/IP includes your IP address in the message (actually, in
each of the packets if more than one is required) and sends it to the IP address
that is obtained by looking up the domain name in the Uniform Resource
Locator you requested or in the e-mail address you're sending a note to. At the
other end, the recipient can see the IP address of the Web page requestor or the
e-mail sender and can respond by sending another message using the IP address
it received.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as W eb site
building and virtual hosting.
ADSL Ethernet Modem

DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network
administrators manage centrally and automate the assignment of Internet
Protocol (IP) addresses in an organization's network. Using the Internet's set of
protocol (TCP/IP), each machine that can connect to the Internet needs a
unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer and,
if computers move to another location in another part of the network, a new IP
address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.
DHCP uses the concept of a "lease" or amount of time that a given IP address
will be valid for a computer. The lease time can vary depending on how long a
user is likely to require the Internet connection at a particular location. It's especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks
in which there are more computers than there are available IP addresses.
DHCP supports static addresses for computers containing Web servers that
need a permanent IP address.
Download - To receive a file transmitted over a network. In a communications
session, download means receive, upload means transmit.
Driver - A workstation or server software module that provides an interface
between a netw ork interface card and the upper-la y er protocol softw are running
in the computer; it is designed for a specific NIC, and is installed during the
initial installation of a network-compatible client or server operating system.
Ethernet - IEEE standard network protocol that specifies how data is placed
on and retrieved from a common transmission medium. Has a transfer rate of
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
Firmware - Programming that is inserted into programmable read-only memory (programmable read-only memory), thus becoming a permanent part of a
computing device.
Gateway - A device that interconnects networks with different, incompatible
communications protocols.

Software- Instructions for the computer. A series of instructions that performs
a particular task is called a "program." The tw o major categories of softw are are
"system software" and "application software." System software is made up of
control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the
user.
A common misconception is that software is data. It is not. Software tells the
hardware how to process the data.
Switch - 1. A data switch connects computing devices to host computers,
allowing a large number of devices to share a limited number of ports. 2. A
device for making, breaking, or changing the connections in an electrical circuit.
TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the
basic communication language or protocol of the Internet. It can also be used
as a communications protocol in a private network (either an intranet or an
extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer
that you may send messages to or get information from also has a copy of
TCP/IP.
Throughput - The amount of data mov ed successfully from one place to another in a given time period.
Upload - To receive a file transmitted over a netw ork. In a communications session, upload means transmit, download means receive.
UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are
twisted around each other. Each signal on twisted pair requires both wires.
Since some telephone sets or desktop locations require multiple connections,
twisted pair is sometimes installed in two or more pairs, all within a single
cable.
ADSL Ethernet Modem
12
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
Mbps (MegaBits Per Second) - One million bits per second; unit of measurement for data transmission.
Network- A system that transmits any combination of voice, video and/or data
between users.
NIC (Network Interface Card) - A board installed in a computer system, usually a PC, to pro vide netw ork communication capabilities to and from that computer system. Also called an adapter.
Ping - (Packet INternet Groper) An Internet utility used to determine whether
a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal computer are external sockets for plugging in communications lines, modems and
printers.
PPPoE(Point to Point Protocol over Ethernet) - A method used mostly b y DSL
providers for connecting personal computers to a broadband modem for
Internet access. It is similar to how a dial-up connection works but at higher
speeds and quicker access.
RJ-11 (Registered Jack-11) - A telephone connector that holds up to six wires.
The RJ-11 the common connector used to plug a telephone into a wall.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Router - Protocol-dependent device that connects subnetworks together.
Routers are useful in breaking down a very large network into smaller subnetworks; they introduce longer delays and typically have much lower throughput
rates than bridges.
Server - Any computer whose function in a network is to provide user access
to files, printing, communications, and other ser vices.
