AC Disconnect detection involves the induction of low AC signal in addition to the 48 VDC operating voltage. The
returned AC signal amplitude is monitored by the PSE at the port terminals. During normal operation, the PD's
relatively low impedance lowers the returned AC signal while a sudden disconnection of this PD will cause a surge
to the full AC signal level and will indicate PD disconnection.
