DSL-G624T Wireless A DSL Router User’s Guide
Introduction
This section provides a brief description of the Router, its associated technologies and a list of Router features.
Router Description and Operation
The DSL-G624T Router is designed to provide a simple and cost-effective ADSL Internet connection for a private
Ethernet or 802.11g/802.11b wireless network. The Router combines high-speed ADSL Internet connection, IP routing
for the LAN and wireless connectivity in one package.
The Router is easy to install and use. The DSL-G624T connects to an Ethernet LAN or computers via standard Ethernet
ports. The ADSL connection is made using ordinary telephone line with standard connectors. Multiple workstations can
be networked and connected to the Internet using a single Wide Area Network (WAN) interface and single global IP
address. 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.
ADSL
Asymmetric Digital Subscriber Line (ADSL) is a broadband network technology that utilizes standard twisted-pair
copper wire telephone lines to enable broadband high-speed digital data transmission and bandwidth hungry
applications for business and residential customers.
ADSL routers and modems provide faster downloads and more reliable connectivity to the user without loss of quality
or disruption of voice/fax telephone capabilities.
ADSL service operates at speeds of up to 8 Mbps downstream and up to 640 Kbps upstream. A secure dedicated point-
to-point connection is established between the user and the central office of the service provider.
802.11g Wireless
The embedded 802.11g wireless access point provides Internet access and connectivity to the Ethernet for 802.11g and
802.11b wireless workstations. IEEE 802.11g is fully compatible with IEEE 802.11b wireless devices. The 802.11g
standard supports data transfer rates of up to 54 Mbps. The Router’s wireless access point supports common security
protocols used for wireless LAN including WEP encryption, 802.1x and WPA.
Router Features
The DSL-G624T Wireless ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet portal
suitable for most small to medium sized offices. DSL-G624T advantages include:
• 802.11g Wireless Access Point – The built-in 802.11g wireless access point connects 802.11g and 802.11b
wireless devices to the Internet and the Ethernet.
• PPP (Point-to-Point Protocol) Security – The DSL-G624T ADSL Router supports PAP (Password
Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.
• DHCP Support – 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-G624T 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-G624T supports TCP/IP protocol, the
language used for the Internet. It is compatible with access servers manufactured by major vendors.
