Port and Cable Assignments
RJ-45 Ethernet Port
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 RJ-45 Ethernet port on the FTTH CPE can be set as an MDI or MDI-X port,
which allows straight-through cable to be used for a connection to a computer,
switch/hub, or other network device. 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.
