ABSTRACT:
The invention relates to a switching module for asynchronous time multiplex comprising at least one junction switch for transmitting packet-switched information from one bus (14) to another bus (16). The junction switch comprises a translation memory (9) for translating packet addresses into new addresses, a comparator (10) for selecting the packets that are to be routed to another bus, a queue memory (12) for storing selected packets until an insertion circuit places the selected packets into the queue memory (12) on the other bus (16). With the aid of a such junction switch, a flexible network structure can be realized, the traffic of packets on the different buses can be mutually asynchronous and virtual circuits can be realized with the aid of the translation memory (9).
