Abstract
Communications over a wired data telecommunications network between and among power sourcing equipment (PSE), powered devices (PDs), and the like, take place over the wired medium by modulating an inline power signal. Any suitable communications protocol may be used and any suitable modulation scheme can be used. Examples of information to be communicated include: changing power requirements or capabilities (higher or lower) and acknowledgements thereof (permitting finer power class gradation than available under existing standards); sensor data; wireless data converted to wired data; status signaling, and the like. Such communications may be used for a number of purposes including supporting redundant provision of services over a network.
