A power line communications system has a power line (120) having a plurality of phase lines (Red, Yellow, Blue) upon which noise level varies with time. The system determines quiet periods when noise upon the phase lines is at a reduced level and transmits one or more data packets within the quiet periods, preferentially transmitting to the subscriber stations (S1, S2 ...) during quiet periods occurring on the phase line to which they are coupled. This increases data throughput in the system.
