PoE communication bus, interface, and protocol between PoE subsystem and PHY or switch subsystems

摘要

Provided is a communications interface system. The communications interface system includes one or more protocol modules configured to include interface protocols that facilitate direct communication between a switching subsystem, a physical layer subsystem, and a Power over Ethernet subsystem. The protocol modules are connectable to a communications bus, the direct communication occurring across the communications bus in accordance with the protocols.
