Abstract:
A method is disclosed that includes receiving a classification voltage at a powered device from a network. The classification voltage includes a baseline voltage level that is below an operating voltage range of the powered device and includes a sequence of distinct signal elements derived from the classification voltage. The method further includes detecting a number of signal elements of the sequence of distinct signal elements. A current is drawn until the number of signal elements exceeds a predetermined number.
