ABSTRACT:
A method of operating pulse code modulated time division multiplex networks in which the subscriber stations participating in a connection receive the information intended for them on the basis of an interpretation of their respective address. The address is transmitted from the sending end exchange in conjunction with the message signals. The message signals to be transmitted are produced from a given subscriber station responsive to that subscriber station receiving its own address transmitted from the terminal exchange in the time slot allocated to the connection in question. This occurs while the subscriber stations modulate and relay in the direction of transmission the unmodulated byte received after their addresses in accordance with the message signals to be delivered by them.
