ABSTRACT:
Time-division switch under the control of a control arrangement in which at least one processor (3) and a clock (4) are associated and including a data bus (5) operation of which is time-shared between equipment access modules (2A to 2E) which are connected to said data bus. Each unit is provided with two content-addressable memories (6A to 6E, 7A to 7E) which are dynamically programmed by the control arrangement to send and to receive data with different frame structures during time slots the number and temporal positions of which are defined by said control arrangement on the data bus and on a particular time-division multiplex link (1A to 1E) linking the relevant equipment access module to the item of equipment it serves.
