18. A system comprising:
-
a transmission detector configured to be coupled to a power line, wherein the detector is configured to detect a received data transmission on the power line and indicate via a first output signal that a data transmission is being received; and a switched-mode power supply coupled to the first output signal and configured to be coupled to the power line, wherein the switched-mode power supply modifies its switching behavior when the first signal indicates a data transmission is being received, wherein the switched-mode power supply modifies it switching behavior such that more channel resources are available for the data transmission being received. - View Dependent Claims (19, 20)
