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 communication between a switching subsystem, a physical layer subsystem, and a Power over Ethernet subsystem. The protocol modules are connectable to a communications bus.

主权项

1. A communications device, comprising:
a Power over Ethernet (PoE) device comprising a first protocol module, wherein the first protocol module is configured to implement one or more interface protocols; and a switching device comprising a second protocol module, wherein the second protocol module is configured to implement the one or more interface protocols, wherein the one or more interface protocols facilitate communication between the switching device, a transceiver physical layer (PHY) device, and the PoE device, wherein the first protocol module and the second protocol module are directly connected to a communications bus, and wherein the switching device and the transceiver PHY device are configured for direct connection to one another and to the PoE device, the direct connection occurring within the communications bus.
