4.3Twisted Pair Pinout Configuration

This section provides the RJ-45 pinout configuration for Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) Physical Layer Medium Dependent (PMD) ports.

Note: When connecting two twisted pair ports together, a transmit and receive cross-over must occur between the two devices (within the cable).
