Abstract: A method for communicating settable priority data from a powered device being powered over communication cabling to power sourcing equipment, the method comprising: prior to connecting power to operational circuitry of the powered device, transmitting first multi-bit data from the powered device to the power sourcing equipment; subsequent to the transmitted first multi-bit data, connecting power received over the communication cabling to the powered device operational circuitry; receiving information from the powered device operational circuitry; disconnecting the received power from the powered device operational circuitry; and subsequent to the disconnecting, and prior to reconnecting power to the operational circuitry, transmitting second multi-bit data from the powered device to the power sourcing equipment, the second multi-bit data being a function of the received information, at least one of the first multi-bit data and the second multi-bit data being a function of a settable priority.

Abstract: A method of asynchronous data reception, the method comprising: receiving a plurality of calibration bits having a bit rate; sampling the received calibration bits at a sampling rate, the sampling rate being in excess of the bit rate; determining, responsive to the sampling, respective indexes for valuing each of the sampled calibration bits; receiving a plurality of data bits having the bit rate; sampling the received plurality of data bits at the sampling rate; and valuing each of the sampled received plurality of data bits responsive to the respective determined indexes.

Abstract: An apparatus and method is disclosed to manage multiple power supplies in a Power over Ethernet (PoE) communication system. The PoE communication system provides PoE to one or more powered devices (PDs) using one or more DC voltage supplies. The PoE communication system includes a power source equipment (PSE) controller that monitors the one or more DC voltage supplies based on the dynamic needs of one or more PDs using power status indicators received via a power bank data interface. The PSE controller includes a multiple power supply management (MPSM) module to receive the power status indicators via the power bank data interface. The MPSM module compares the values of received power status indicators with default or stored power status indicators.
