collaborative computing, distance learning, movies on demand and multi-player
video gaming, without experiencing any loss of quality or disruption of voice/fax
telephone capabilities.
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 640 Kbps upstream (to
the ISP), depending on local telephone line conditions. These conditions are ideal
for many 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 DSL-504 ADSL Router supports PAP (Password Authentication Protocol)
and CHAP (Challenge Handshake Authentication Protocol).
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 DSL-504 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.
TCP/IP (Transfer Control Protocol/Internet Protocol)
The DSL-504 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-504 supports both RIP-1 and RIP-2 exchanges with other routers. Using
both versions will allow the Router to communicate with RIP enabled devices.
