Abstract: In one embodiment, a method includes transmitting pulse power on two wire pairs, the pulse power comprising a plurality of high voltage pulses with the high voltage pulses on the wire pairs offset between the wire pairs to provide continuous power, performing low voltage fault detection on each of the wire pairs between the high voltage pulses, and transmitting data on at least one of the wire pairs during transmittal of the high voltage pulses. Data transmittal is suspended during the low voltage fault detection.

Abstract: In one embodiment, a method includes transmitting data on two wire pairs carrying pulse power, wherein the pulse power comprises a plurality of voltage pulses with the voltage pulses on the wire pairs offset between the wire pairs to provide continuous power and identifying transitions between at least one of a pulse-on time and a pulse-off time, and a pulse-off time and a pulse-on time on at least one of the wire pairs. Data transmission on the wire pair is controlled during the identified transitions on the wire pair to prevent interference between the pulse power and the data.
