Router Description and Operation The DSL-504 ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small to medium sized corporate LAN. The DSL-504 combines the benefits of high-speed ADSL connection technology and TCP/IP routing with Ethernet capabilities in one compact and convenient package. ADSL connection technology enables many interactive multimedia applications such as video conferencing and collaborative computing. The Router is easy to install and use. The DSL-504 offers four dedicated Ethernet LAN ports using standard RJ-45 connectors. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors. This arrangement means that several PCs can be networked and connected to the Internet. The Router can be used for IP packet routing over the WAN and also supports transparent bridging. The Router is ideal for secure telecommuting through the use of virtual private networks (VPN). Cost saving capabilities of the Router includes NAT (Network Address Translator) and DHCP (Dynamic Host Configuration Protocol), which allow you connect several hosts to the Internet using a single global IP address. ADSL Technology Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes ordinary copper telephone lines to enable broadband high-speed digital data transmission and interactive multimedia applications for business and residential customers. Using existing copper telephone lines forgoes the need for upgrading or adding expensive new cable. ADSL devices use digital coding techniques that greatly increase the potential capacity of phone lines without interfering with regular telephone services. For the ADSL user, this means much faster data communications and the potential for interactive video capabilities. ADSL devices make it possible to enjoy benefits such as high-speed Internet access, telecommuting (remote LAN access), collaborative computing, distance learning, movies on demand and multi-player video gaming, without experiencing any loss of quality or disruption of voice/fax telephone capabilities. 1

Introduction
This chapter describes the DSL-504 ADSL Router and its features and gives a
brief introduction to ADSL technology.
Router Description and Operation
The DSL-504 ADSL Router is designed to provide a simple, cost-effective and
secure ADSL Internet connection for your small to medium sized corporate LAN.
The DSL-504 combines the benefits of high-speed ADSL connection technology
and TCP/IP routing with Ethernet capabilities in one compact and convenient
package. ADSL connection technology enables many interactive multimedia
applications such as video conferencing and collaborative computing.
The Router is easy to install and use. The DSL-504 offers four dedicated Ethernet
LAN ports using standard RJ-45 connectors. The ADSL connection is made using
ordinary twisted-pair telephone line with standard RJ-11 connectors. This
arrangement means that several PCs can be networked and connected to the
Internet.
The Router can be used for IP packet routing over the WAN and also supports
transparent bridging. The Router is ideal for secure telecommuting through the
use of virtual private networks (VPN). Cost saving capabilities of the Router
includes NAT (Network Address Translator) and DHCP (Dynamic Host
Configuration Protocol), which allow you connect several hosts to the Internet
using a single global IP address.
ADSL Technology
Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes
ordinary copper telephone lines to enable broadband high-speed digital data
transmission
and
interactive
multimedia
applications
for
business
and
residential customers. Using existing copper telephone lines forgoes the need for
upgrading or adding expensive new cable.
ADSL devices use digital coding techniques that greatly increase the potential
capacity of phone lines without interfering with regular telephone services. For
the ADSL user, this means much faster data communications and the potential
for interactive video capabilities. ADSL devices make it possible to enjoy benefits
such as high-speed Internet access, telecommuting (remote LAN access),
collaborative computing, distance learning, movies on demand and multi-player
video gaming, without experiencing any loss of quality or disruption of voice/fax
telephone capabilities.
