Abstract
In a method and apparatus for the two-way transmission of pulses between a plurality of out-stations generally connected to a common power supply network and at least one control unit, the data is applied to the power supply network using pulse code modulation so that the power supply network serves as a data bus bar between the out-stations and the control unit. A multiplexing of the data applied to the network permits individual communication between an out-station and the control unit during an assigned time slot with the power supply frequency being used for synchronizing the timing of the multiplex system.
