Router Features 

The DSL-502G ADSL Ethernet Router utilizes the latest ADSL enhancements to provide a reliable Internet 

portal suitable for most small to medium sized offices. DSL-502G advantages include: 

•  PPP (Point-to-Point Protocol) Security The DSL-502G ADSL Router supports PAP (Password 

Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections. 

•  DHCP Support DHCP (Dynamic Host Configuration Protocol) automatically and dynamically assigns al 

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-502G 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-502G 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-502G 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 a 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-502G 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. 

•  Full Network Management The DSL-502G 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-502G 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.
