A method for transmitting data in the form of a sequence of data words [Fig. 2] according to PLBus power line carrier communications protocol in a channel (20) carrying data transmitted, according to a different protocol, in the form of timed bursts of a signal, by producing (16) a carrier which is continuous, in the sense that it spans two consecutive zero crossings of the power frequency, at least for the duration of each data word, angularly modulating (14,16) the carrier in accordance with the information contained in each data word, and transmitting (18) the angularly modulated carrier in the channel. |
