Abstract
Functionality of a powerline communication (PLC) power supply and modem interface can be implemented using a power supply processing unit and a PLC modem unit that can be coupled together using standard, two-wire cabling. The power supply processing unit can generate a DC power signal and a zero cross signal based on an AC powerline signal received via a PLC network. The power supply processing unit can modulate the zero cross signal onto the DC power signal. The power supply processing unit can then generate a composite PLC signal comprising a PLC signal (extracted from the AC powerline signal) and the DC power signal modulated with the zero cross signal. The PLC modem unit can extract the PLC signal, the DC power signal, and the zero cross signal from the composite PLC signal, and then can process the PLC signal based on information associated with the zero cross signal.
