Abstract

Metodo per stabilire un bus di comunicazione, comprendente il collegare una pluralità di ricetrasmettitori a un apparecchio di commutazione a divisione di spazio automatico, e il collegare detti ricetrasmettitori in serie attraverso l'apparecchio di commutazione per formare una struttura di bus ripiegata, uno di detti ricetrasmettitori formando un bus principale per iniziare e terminare treni di segnali.
