Router Features
The DSL-504T ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet
portal suitable for most small to medium sized offices. DSL-504T advantages include:
PPP (Point-to-Point Protocol) Security –
(Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol)
for PPP connections.
DHCP Support – 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-504T 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-504T supports TCP/IP
protocol, the language used for the Internet. It is compatible with access servers manufactured
by major vendors.
RIP – The DSL-504T supports RIP (RIP V1 compatible) to exchange routing information with
other routers.
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-504T 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 eight
Mbps downstream bit rate using the G.dmt.

Easy Installation – The DSL-504T 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.
