ABSTRACT:
A management unit for a unit for switching data transmitted by asynchronous time-division multiplexing. It comprises input circuits (gme, gpe) adapted to receive cells present on the input bus (BE) of the switching unit and output circuits (grs, grv) adapted to supply cells on the output bus (BS) of the switching unit. The input circuits comprise a call circuit (gpe) detecting a call signal (adl) from the switching unit and commanding the writing of the cell present on the input bus (BE) into an input memory (gme). The output circuits comprise a transmit circuit (gpl) receiving an availability signal (fv) and determining the transmission of the cell that an output register (grs, grv) contains on the output bus (BS).
