<p>The system of this invention, which purpose is to allow the simultaneous realization of a number of conferences with a minimum presence of transmitted signals into the corresponding reception channel, is constituted by a functional association of a series of digital hybrids (1) that serve as a bond between a switching matrix (2) with the remote control units (3). The controlling function is carried out by a micro-controller unit (4) through a control bus (13) and through an interface (5) for hybrids (1), a switching matrix and the remote control units (3). <IMAGE></p> |
