Abstract
In a PCM time multiplex telecommunications network the digital signal input of the coder/decoder of each subscriber station has an individually controllable receiving memory connected to the input of the coder/decoder, and the digital signal output of the respective coder/decoder has an individually controllable transmitting memory connected thereto. The control of the signal receipt and transmission by the coder/decoder takes place at different points in time than the receipt of PCM signals by the receiving memory, and the transmission of PCM signals by the transmitting memory.
