1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections
should also work for 1000BASE-T, providing that all four wire pairs are
connected. However, it is recommended that for all critical connections, or
any new cable installations, Category 5e (enhanced Category 5) or
Category 6 cable should be used. The Category 5e and 6 specifications
include test parameters that are only recommendations for Category 5.
Therefore, the first step in preparing existing Category 5 cabling for
running 1000BASE-T is a simple test of the cable installation to be sure
that it complies with the IEEE 802.3ab standards.
