• PPP (Point-to-Point Protocol) Security – The DSL-2540U ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge
Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP.
• 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-2540U 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-2540U 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-2540U 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-2540U 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-2540U 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-2540U 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.
