Abstract

Un microprocesseur de commande 114 envoie des signaux appropriés sur un bus de commande à faible vitesse 116 vers un générateur de balayage 118. Ce dernier génère à son tour des signaux de commande S1,...,Sn pour les terminaisons de communication 102, 104,..., 108 pendant les canaux temporels appropriés. Le bus 110 (TX) est connecté à un bus 112 (RX) par un simple circuit de retard 120. Le microprocesseur 114 est adapté pour attribuer toujours aux deux terminaisons qui doivent etre interconnectées des canaux temporels qui sont écartés de T/2 secondes ou une demi-trame.
