Port and Cable Assignments

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.

An Ethernet twisted-pair link segment requires two pairs of wires. Each wire pair is

identified by two different colors. Each wire pair must be attached to the RJ-45

connector in a specific orientation detailed below.

The Ethernet port on the modem is an MDI-X port, which allows straight-through

cable connections to PCs, and to hubs and switches with MDI ports. In

straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected

straight through to pins 1,2, 3 and 6 at the other end of the cable. For connection to

hubs or switches which have MDI-X ports, a cross-over cable must be used.
