Network Connections

Connect ADSL Line
Use the ADSL cable included with the Modem 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 Modem 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 Modem to Ethernet
The Modem may be connected to a single computer or Ethernet device through the 10BASE-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 Modem to any
Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the
connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Modem is a crossed port (MDI-X). Follow standard
Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the Modem directly to a PC or server use a
normal straight-through cable. You should use a crossed cable when connecting the Modem to a normal (MDI-X) port on a switch or hub. Use a
normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply to
the LAN to Modem connection. Be sure that the cable connecting the LAN to the Modem does not exceed 100 meters.
Hub or Switch to Modem Connection
Connect the Modem to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on
the switch or hub for another device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Modem Connection
You can connect the Modem directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided.
