Techniques for measuring network channel resistive loss between a power-sourcing apparatus and a powered device
摘要：
A method and apparatus are provided for determining resistive power loss through a channel between Power Sourcing Equipment (PSE) and a Powered Device (PD). The method includes (1) receiving indication that a PSE signal measurement is available from the PSE or a PD signal measurement is available from the PD, (2) selecting, as an input parameter to a processing operation, at least one of the PSE signal measurement or the PD signal measurement, (3) performing the processing operation to calculate a resistance value indicative of the resistive power loss through the channel between the PSE and PD based on the input parameter, and (4) outputting the resistive power loss value as a result of carrying out the processing operation.
