A set of first and second crosspoint devices, each containing a crosspoint switch and each having first and second opposed sides and third and fourth opposed sides, and wherein in said first device, said first side contains input pins, said second side contains control pins, said third side contains expansion data input pins, and said fourth side contains output pins, and in said second device, said first side contains control pins, said second side contains input pins, said third side contains expansion data input pins arranged in the reverse order from that of the expansion data input pins of said first side of said first device, and said fourth side contains output pins arranged in the reverse order from that of the output pins of said first device. The combination of standard and mirror configurations allows more compact assembly of the devices, with standard and mirror image devices located on opposite sides of a circuit board.

L'invention est un ensemble constitué d'un premier et d'un second dispositifs de croisement portant chacun un commutateur de croisement ayant chacun un premier et un second côtés opposés et un troisième et un quatrième côtés opposés. Dans le premier dispositif, le premier côté porte des broches d'entrée, le second côté des broches de commande, le troisième côté des broches d'entrée de données d'expansion et le quatrième côté des broches de sortie. Dans le second dispositif, le premier côté porte des broches de commande, le second côté des broches d'entrée, le troisième côté des broches d'entrée de données d'expansion disposées dans l'ordre inverse de celles du premier côté du premier dispositif, et le quatrième côté des broches de sortie disposées dans l'ordre inverse de celles du premier dispositif. La combinaison de la configuration standard et de la configuration image permet d'obtenir un ensemble plus compact pour les dispositif, les dispositifs standard et image se trouvant sur les côtés opposés d'une même carte de circuit.
