Features

• PPP (Point-to-Point Protocol) Security – The DSL-2640R ADSL Router supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP.

• DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your
network. This eliminates the need to reconfigure every host whenever changes in network topology occur.

• Network Address Translation (NAT) – For small office environments, the DSL-2640R allows multiple users on the LAN to access the
Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user.
NAT improves network security in effect by hiding the private network behind one global and visible IP address. NAT address mapping can
also be used to link two IP domains via a LAN-to-LAN connection.

• TCP/IP (T ransfer C ontrol Protocol/Internet Protocol) – The DSL-2640R supports TCP/IP protocol, the language used for the Internet. It is
compatible with access servers manufactured by major vendors.

• RIP-1/RIP-2 – The DSL-2640R supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router to
communicate with all RIP enabled devices.

• Static Routing – This allows you to select a data path to a particular network destination that will remain in the routing table and never “age
out”. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for
example to another router or a server) or outside your network (to an ISP defined default gateway for instance).

• Default Routing – This allows you to choose a default path for incoming data packets for which the destination address is unknown. This is
particularly useful when/if the Router functions as the sole connection to the Internet.

• Precise ATM Traffic Shaping – Traf fic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the
Quality of Service for ATM data transfer.

• Full Network Management – The DSL-2640R incorporates SNMP (Simple Network Management Protocol) support for web-based
management and text-based network management.

• Easy Installation – The DSL-2640R uses a web-based graphical user interface program for convenient management access and easy set
up. Any common web browser software can be used to manage the Router.

Power

Steady green light indicates the unit is powered on.
This remains dark when power is off. A red colored
Power LED indicates system failure.

Hardware Overview

LEDs

WLAN

Steady green lig ht indica te s a
wireless connection. A blinking
green light indicates activity on
the Wireless LAN interface.

DSL

A steady green light indic ates a
valid ADSL connection. This will
light after the ADSL negotiation
process has been settled. A
blinking green light indicates
activity on the WAN (ADSL)
interface.

Internet

A solid green light indicates the WAN IP address from IPCP or
DHCP and DSL is up or a static IP address is configured and

LAN

A solid green light indicates a valid link on
startup. This light will blink when there is activity
currently passing through the Ethernet port.

PPP negotiation has been su ccessf ully completed. If the
indicator blinks green, this means the Router is active. If the
Router power is off, this remains dark. A solid red light indicates
there is no DHCP response, no PPPoE response, PPPoE
authentication has failed, and/or there is no IP.

Section 2 – Installation

Installation

This section will walk you through the installation process. Placement of the Wireless ADSL Router is very important. Do not place the Router in an
enclosed area such as a closet, cabinet, or in the attic or garage. Place the Wireless ADSL Router in a location where it can be easily connected to
Ethernet devices, the telephone line as well as to a power source.

Before You Begin

Please read and make sure you understand all the prerequisites for proper ins tallation of your new Router. Have all the necessary information and
equipment on hand before beginning the installation.

Installation Notes

In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some
users, only their account information (Username and Passwo rd) is required. For others, various parameters that control and define the Inte rnet
connection will be required. You can print out the two pages below and use the tables to l ist thi s informatio n. Th is way yo u have a hard copy of all
the information needed to setup the Router. If it is necessary to reconfigure the d evice, all the necessary information can be easily accesse d. Be
sure to keep this information safe and private.

Low Pass Filters

Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to
avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy
to install passiv e devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.

Operating Systems

The DSL-2640R uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any
operating system capable of running web browser software, including Windows 98 SE, Windows ME, Windows 2000, Windows XP, and Windows
Vista.

Section 2 – Installation

Web Browser

Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to
work best with more recently released browsers such as Opera, Microsoft Internet Explorer® version 6.0, Netscape Navigator® version 6.2.3, or
later versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not
been disabled by other software (such as virus protection or web user security packages) that may be running on your computer.

Ethernet Port (NIC Adapter)

Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection
and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port
already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer
does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the
installation instructions that come with the Ethernet NIC adapter.

Additional Software

It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if
you are using the device a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored
on another computer or gateway device, not in the Router itself.

If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection
can be stored in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some
settings in the device, including account information used to identify and verify the connection.

All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled
device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be
assigned in a number of ways. Y our network service provider will give you instructions about any additional connection software or NIC
configuration that may be required.

Wireless LAN

Computers using the Wireless network can access the Internet or use the embedded 802.1g wireless access point. Wireless workstations must
have an 802.1g or 802.1b wireless network card installed to use the Wireless ADSL Router. In addition the workstations must be configured to
operate on the same channel and SSID as the Wireless ADSL Router. If wireless security is used, the wireless workstations must be properly
configured for the security settings used.
