7.1.1. 1000BASE-T/100BASE-TX/10BASE-T Port
The 1000BASE-T/100BASE-TX/10BASE-T is a port that supports adaptation of three rates,
and automatic MDI/MDIX Crossover at these three rates.
The 1000BASE-T complies with IEEE 802.3ab, and uses the cable of 100-ohm Category-5 or
Supper Category-5 UTP or STP, which can be up to 100 m (328 feet).
The 1000BASE-T port uses four pairs of wires for transmission, all of which must be connected.
Figure A-1 shows the connections of the twisted pairs used by the 1000BASE-T port.
Figure A-1 Schematic Diagram for the Four Twisted Pairs of the 1000BASE-T
In addition to the above cables, the 100BASE-TX/10BASE-T can also use 100-ohm Category-3,
4, 5 cables for 10 Mbps, and 100-ohm Category-5 cables for 100 Mbps, both of which can be up
to 100 m (328 feet). Figure A-2 shows the pinouts of the 100BASE-TX/10BASE-T.

Figure A-3 shows the straight-through and crossover cable connections for the 100BASE-
TX/10BASE-T.
