Abstract
In a particular embodiment, a method includes receiving a powered device (PD) detection signal at a PD from a powered network and applying the PD detection signal to an external resistor to provide a detection signature to the powered network. Further, the method includes receiving a PD classification mark signal at the PD, applying the received PD classification mark signal to the external resistor, and selectively activating a classification mark current path in parallel with the external resistor to produce a classification mark signature.
