D-Link DSL-504 User Manual - Product Features
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.
