Features 

•  PPP (Point-to-Point Protocol) Security – The DSL-2500U 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-2500U 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-2500U supports TCP/IP protocol, the language used for the Internet. It is 

compatible with access servers manufactured by major vendors. 

•  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-2500U 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.
