>>> DSL-2640T Specification and feature
>>>Router Description and Operation
The DSL-2640T Wireless ADSL2+ Router is designed to provide connectivity for your private Ethernet LAN, and 802.11g/802.11b wireless LAN to the Internet via an ADSL connection.
The Router is easy to install and use. Standard Ethernet ports are used to connect to computer or other Ethernet devices.
The 802.11g wireless interface provides connectivity to 802.11g or 802.11b wireless devices.
>>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 wireless Router supports 64-bit and 128-bit WEP encryption.
>>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.
ADSL2+ routers and modems provide faster downloads and more reliable connectivity to the user without loss of quality or disruption of voice/fax telephone capabilities.
ADSL2+ provides a dedicated service over a single telephone line operating at speeds of up to 24Mbps downstream and up to 1Mbps upstream, depending on local telephone line conditions. A secure point-to-point connection is established between the user and the central office of the service provider.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format, and upper
layer protocols.
>>>Router Features
The DSL-2640T ADSL 2+ Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for most small to medium sized offices. DSL-2640T advantages include:
• PPP (Point-to-Point Protocol) Security – The DSL-2640T ADSL 2+ 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 all 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-2640T 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-2640T 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-2640T supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router to communicate with all RIP enabled devices.
• Static Routing – This allows you to select a data path to a particular network destination that will remain in the routing table and never “age out”. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for example to another router or a server) or outside your network (to an ISP defined default gateway for instance).
• Default Routing – This allows you to choose a default path for incoming data packets for which the destination address is unknown. This is particularly useful when/if the Router functions as the sole connection to the Internet.
• ATM (Asynchronous Transfer Mode) – The DSL-2640T supports Bridged Ethernet over ATM (RFC1483), IP over ATM (RFC1577) and PPP over ATM (RFC 2364).
• Precise ATM Traffic Shaping – Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the Quality of Service for ATM data transfer.
• G.hs (Auto-handshake) – This allows the Router to automatically choose either the G.lite or G.dmt ADSL connection standards.
• High Performance – Very high rates of data transfer are possible with the Router. Up to 8 Mbps downstream bit rate using the G.dmt standard.
• Full Network Management – The DSL-2640T incorporates SNMP (Simple Network Management Protocol)
support for web-based management and text-based network management via an RS-232 or Telnet connection.
• Telnet Connection – The Telnet enables a network manager to access the Router’s management software remotely.
• Easy Installation – The DSL-2640T uses a web-based graphical user interface program for convenient management access and easy set up. Any common web browser software can be used to manage the Router.
