Product Description
The DSL-2640T wireless ADSL router is a versatile, high-speed remote router for
home and the small office. With integrated ADSL2/2+ supporting up to 24Mbps
download speed, firewall protection, Quality of Service (QoS), 802.11g wireless
LAN and 4 Ethernet switch ports, this router provides all the functions that a
home or small office needs to establish a secure and high-speed remote link to
the outside world.
High-Speed ADSL Connection.
The DSL-2640T features the latest ADSL2/ADSL2+ standards, providing speeds of up
to 24Mbps downstream and 1Mbps upstream (ADSL2+), or 12Mbps downstream and 1Mbps
upstream (ADSL2). This router auto-senses the connection type and
auto-negotiates the best modulation scheme, using the G.hs (handshake) protocol.
Ready Wireless LAN & Ethernet Connection for Workgroup.
The DSL-2640T provides an integrated 802.11g WLAN interface supporting wireless
speeds of up to 54Mbps and interoperability with 802.11b wireless devices on the
2.4GHz frequency band. It also provides four 10/100Mbps Ethernet switch ports
for ready workstations connection. These built-in functions save you the cost
and trouble of installing a separate wireless access point and an Ethernet
switch.
Firewall Protection.
The router provides firewall security using Stateful Packet Inspection (SPI) and
hacker attack logging for Denial of Service (DoS) attack protection. SPI
inspects the contents of all incoming packet headers before deciding what
packets are allowed to pass through. Access control is provided with packet
filtering based on port and source/destination MAC/IP addresses. With Virtual
Server Mapping, the router can be set to allow separate FTP, Web, and multiple
games to share the same Internet-visible IP address while still protecting your
servers and workstations from hackers. You can configure any of the built-in LAN
ports of the router to function as a DMZ port. VPN pass-through is provided to
let mobile users access files and mail from offices to work at home without
having to use complex VPN client software.
Quality of Service Features.
The DSL-2640T supports 4 priority queues to enable a group of home or office
users to experience the benefit of smooth network connection of inbound and
outbound data without concern of traffic congestion. This QoS support allows you
to enjoy high ADSL transmission for applications such as VoIP, multimedia and
on-line games over the Internet.
