ABSTRACT:
A circuit arrangement is provided for a communications system for transmitting serial bit message information, particularly for multiplex data transmitted within optical transmission systems, by way of which local networks having loop configurations and equipped with corresponding switching devices, a plurality of terminal equipment processing different types of communication being connectible to the local network in an arbitrary combination with one another, the plurality being adapted to the different types of communication with respect to quantity of data transmission and data transmission rate within a frame, and in view of the method of transmission. Considering the maximum quantity of data to be transmitted via a frame within a defined time, the loop network is sub-divided into loop sub-networks in which at least one broadband subscriber terminal and a plurality of narrow band subscriber terminals are provided supplementing one another up to the maximum data quantity in each loop sub-network, whereby the data of the broadband subscriber terminal are gated out by way of a sub-loop interface device and are centrally switched via a centrally-controlled broadband space switching matrix network device and are again gated back into the corresponding sub-network.
