    Abstract: A PCM switching unit, adapted to carry out the insertion of a word into a PCM channel, the transfer of a word from a PCM channel or from the switching unit control memory towards the control unit, and the extraction of a channel, in particular channel 0, from one or more PCM channels. These modes of operation are carried out by using a bidirectional data bus, for the interconnection between the switching unit and the control unit, which may be a microprocessor.
