Twisted-pair Cable

Caution:

DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with
RJ-45 connectors that conform with FCC standards.

For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire
pair is identified by two different colors. An RJ-45 connector must be attached to both ends of the cable.
Except for the WAN port, all RJ-45 ports on the SpeedStream 2614 support automatic MDI/MDI-X
configuration, so you can use straight-through cable to attach the LAN ports to any network device.
However, when connecting the WAN port to a broadband modem, you will need to use either straight-
through or crossover cable, depending on the port type used on the modem.

The figure below illustrates how the pin numbering on the RJ-45 connector. Be sure to hold the connectors
in the same orientation when attaching the wires to the pins.
