Patent ID: 8432142

Claim:
A Power Source Equipment (PSE) controller, implemented as part of a PSE, for a Power-over-Ethernet (PoE) communication system, the PSE providing power and data communications to a Powered Device (PD), comprising: a current measurement system configured to measure a current of the PD to provide a measured current; a voltage measurement system configured to measure a voltage of the PD to provide a measured voltage; a temperature measurement system configured to measure a temperature of the current measurement system to provide a measured temperature; and a multiplexer configured to time-division multiplex the measured current, the measured voltage, and the measured temperature to provide a time-division multiplexed signal including a plurality of channels, the multiplexer being further configured to multiplex the measured current into a first channel from among the plurality of channels, the measured voltage into a second channel from among the plurality of channels, and the measured temperature into a third channel from among the plurality of channels.
