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.

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.
