Introduction
This chapter describes the Router and it features and includes brief introduction to ADSL and 802.11b Wireless
LAN. Front and rear panel diagrams are used to illustrate the LED indicators and cable connections.
Router Description and Operation
The DSL-604+ ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet
connection for wired (Ethernet) and wireless (802.11b) stations on your network. The DSL-604+ combines high-
speed ADSL connection technology, TCP/IP routing and 802.11b wireless connectivity in one compact unit.
The Router is easy to install and use. The DSL-604+ connects to an Ethernet LAN via a standard Ethernet
10BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary twisted-pair
telephone line with standard RJ-11 connectors. This arrangement allows wired and wireless workstations to
share network resources and connect to the Internet using a single WAN interface and IP address.
The Router supports transparent bridging or it can be used for IP packet routing over the Internet. Cost saving
features of the Router such as NAT (Network Address Translator) and DHCP (Dynamic Host Configuration
Protocol) improve efficiency and security. The advanced security enhancements, packet filtering and port
redirection, can help protect your network from potentially devastating intrusions by malicious agents from
outside your network.
All the 802.11b wireless settings for the Router are entered on a single page in the web manager. Security for the
wireless interface comes in two forms, WEP Encryption and MAC Address Control.
Product Features
The DSL-604+ ADSL Router utilizes the latest ADSL enhancements and router technologies to provide a robust
Internet gateway suitable for most small to medium sized offices.
PPP (Point-to-Point Protocol) Security
The DSL-604+ ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge
Handshake Authentication Protocol) for PPP connections.
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) automatically and dynamically assigns al 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-604+ 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-604+ 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-604+ supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router
to communicate with all RIP enabled devices.
