certain period (for details, see the IEEE 802.3af specification).
Capacitive Detection: If the port and capacitive detection are enabled, the
capacitances state reads in the voltage result from the constant current. This is the
subtracted from the pre-capacitance voltage to get a charge rate. If this charge rate
is within the window of the PD signatures, the device is considered to be discovered.
