Abstract

Communications signals are transmitted over a power distribution network comprising a substation (10) having a plurality of power lines (40, 41) leading from it for distributing electricity to a plurality of premises S1, S2 and a plurality of communications stations (TRX) coupled to the power lines. Communications signals are coupled to the network at busbars (25) of the substation for transmission over the plurality of lines (40, 41) to the communications stations. Signals can be coupled to the two ends of the busbars and one of the feeds modified with respect to the other whereby to control the combined power that is delivered to the lines.
