Network Connections
Network connections are provided through the ADSL port and Ethernet port on the back of the Router. See the Rear
Panel diagram above and the illustrations below for examples.
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the
cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the RJ-11 wall
socket. If you are using a low pass filter device, follow the instructions included with the device or given to you by your
service provider. The ADSL connection represents the WAN interface, the connection to the Internet. It is the physical
link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10/100 BASE-TX Ethernet port on
the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of
10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at speeds between
0~100Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use Category 5 or better twisted-pair Ethernet cable with RJ-45 connectors. The RJ-45 port on the Router is auto MDI-
X/MDI-II meaning that is will link correctly with either MDI-II through or MDI-X crossed ports.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting
the LAN to the Router does not exceed 100 meters.
