Features

•

PPP (Point-to-Point Protocol) Security –

The DSL-2640B 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-2640B 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 (Transfer Control Protocol/Internet Protocol) –

The DSL-2640B 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-2640B 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 –

Traffic 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-2640B incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based

network management.

•

Easy Installation

–

The DSL-2640B 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.

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.

Mounting the Device on the Wall

Step 1

There are two slots on the device bank. Install two screws on the wall according to the positions of the slots. Keep the two screws at the same horizontal level.

Step 2

Gently fasten the two slots with the screws.

Step 3

Slowly take your hands off the device. Ensure that the device is properly mounted on the wall with the support of the screws.

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 Password) is required. For others, various parameters that control and define the Internet connection will be required. You can print

out the two pages below and use the tables to list this information. This way you have a hard copy of all the information needed to setup the Router. If it is necessary to

reconfigure the device, all the necessary information can be easily accessed. 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 passive 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-2640B 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.

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 as 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
