Guides, Specs, and Important URLs:

• RJ-11 port ADSL telephone line connection
• 1x RJ-45 ports for 10/100BASET Ethernet connection
• 1x USB port

Status Lights:

• Power Steady green light indicates the unit is powered on. When the device is powered off this remains dark.
• Status Lights steady green during power on self-test (POST). Once the connection status has been settled, the light will blink green. If the indicator lights steady green after the POST, the system has failed and the device should be rebooted.
• ADSL: Link/Act Steady green light indicates a valid ADSL connection. This will light after the ADSL negotiation process has been settled. A blinking green light indicates activity on the WAN (ADSL) interface.
• Ethernet: Link/Act A solid green light indicates a valid link on startup. This light will blink when there is activity currently passing through the Ethernet port.
• USB: Link/Act Steady green light indicates a valid USB connection. A blinking green light indicates activity on the USB interface.

Misc Notes:

The Router may be reset to the original factory default settings by depressing the reset button for a few seconds while the device is powered on. Use a ballpoint or paperclip to gently push down the reset button. Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings will be restored to the factory default IP address 10.1.1.1 and the subnet mask is 255.0.0.0, the default management Username is admin and the default Password is admin. 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.
