<p>The invention relates to a switching system composed of switching members, modules and buses, which modules are physical units formed by one or several elements, and are interconnected by means of buses and switching members. The switching members are controllable switches and are arranged in switch groups (S), and they are controlled by means of at least one control unit. In connection with each module (M), there are arranged at least two, advantageously three, switch groups (S1, S2, S3), the first (S1) whereof is connected in between the module (M) and the bus (V), and by intermediation of this switch group the desired linkage channels of the module are connected to the bus which connects the modules to each other. The second switch group (S2) is connected to the bus (V), and thereby the bus channels are divided so that the said first switch groups (S1) and the modules (M) are interconnected via the bus. The possible third switch group (S3) is connected to the linkage channels of the module (M), and thereby the internal switchings of the module are carried out and the desired linkage channels connected to the first switch group (S1).</p> |
