DSL-504 ADSL Router User's Guide ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream (to the user) and up to 800 Kbps upstream (to the ADSL service provider's central office), depending on local telephone line conditions. These conditions are ideal for many time sensitive user applications. A secure point-to-point connection is established between the user and the central office of the ADSL service provider. The user is always connected thus eliminating dial-up time and simplifying connectivity issues. Product Features The DSL-504 ADSL Router utilizes the latest ADSL enhancements and router technologies to provide a robust Internet gateway suitable for most small to medium sized offices. PPP (Point-to-Point Protocol) Security The Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) useful for secure telecommuting and remote access to the LAN. DHCP Support (Dynamic Host Configuration Protocol) DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be automatically and dynamically assigned to hosts on your network. Network Address Translation (NAT) For small office environments, the Router 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 address mapping can also be used to link two IP domains via a LAN-to-LAN connection. VPN (Virtual Private Network) A VPN is a method to provide economical and secure data transfer across a public network (such as the Internet). It is ideal for telecommuting and LAN-to-LAN connection. TCP/IP (Transfer Control Protocol/Internet Protocol) The DSL-504 supports TCP/IP protocol. It is compatible with access servers manufactured by all major vendors. RIP-1/RIP-2 The DSL-504 supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions can allow the Router to communicate with RIP enabled devices. 2
