Router Features
The DSL-502T ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet
portal suitable for most small to medium sized offices. DSL-502T advantages include:
•
PPP (Point-to-Point Protocol) Security – The DSL-502T ADSL Router supports PAP
(Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol)
for PPP connections.
•
DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns
all 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-502T 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-502T 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-502T 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 an 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-502T 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 standard.
•
Full Network Management – The DSL-502T 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-502T 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.
