Abstract
A powered device interface constituted of: a first and second rectifier bridge, the outputs and returns thereof in electrical communication with each other; and a selection circuit; and a classification current circuit in electrical communication with the output and return of each of the first rectifier bridge and the second rectifier bridge, and further in electrical communication with a first and second input of the first rectifier bridge, wherein the classification current circuit is arranged, responsive to a classification voltage received at one of the first rectifier bridge and the second rectifier bridge, to: in the event that the classification voltage is received at the first rectifier bridge, output a first classification current exhibiting a first magnitude; and in the event that the classification voltage is received at the second rectifier bridge, output a second classification current exhibiting a second magnitude.
