ABSTRACT:
An asynchronous time division multiplex switching network for switching multi-service communication data performs point-to-point data switching, data switching between a single calling party and a plurality of called parties, and data switching between plural calling parties and a single called party. The network comprises plural incoming and outgoing time division multiplex highways including asynchronous channels each formed by a packet data and an address label (j, k). Incoming and outgoing terminal switching equipments are respectively connected to the incoming and outgoing highways. A bus interconnects the terminal switching equipments. The labels are converted into several sub-words according to the type of communication switching. In response to the values of these sub-words, the outgoing terminal switching equipments accept or do not accept the packets to be transmitted.
