A communication switch comprises a matrix of switch modules interconnected to allow switching between multiple inputs and multiple outputs, characterised in that said switch modules are distributed between multiple input/output port cards (CD) so that each card incorporates one or more switch modules (SW) with multiple outputs (T1-T4) connected to respective output ports (OUT) of the card and multiple inputs (N1-N8) connected to respective transfer terminals (TR1-TR8) of the card, the inputs (N1-N8) of the switch modules (SW) of all the cards (CD) being interconnected via a set of buses (B1-B8) connected to said transfer terminals (TR1-TR8), and a selector (SL) being incorporated in each card (CD) which is setable to connect each of one or more respective input ports (IN) of the card (CD) to a selected input (N1-N8) of said switch modules (SW) on the same card so that each input port (IN) of the switch is uniquely connected via a respective selector (SL) to a respective input (N1-N8) of a switch module (SW) and to a respective bus (B1-B8). <IMAGE> |
