PURPOSE:To make it possible to secure an alternative route as occasion demands by simplifying an information transfer process, by transferring transmitting inforamtion equivalent to a transmission request on reference to the content of a node channel table by a time-division multivibrator which has received the transmission request. CONSTITUTION:By time-division multivibrators 2-0, 2-1 and 2-2, information equivalent to each transmission request is assigned to an idle time slot among time slots of time-division multiple circuits 21...26 and then transmitted, and the node channel table in the node control NC indicates a channel for the transfer to port adapters 14...16 belonging to multivibrators 2-1 and 2-2 adjacent to multivibrator 2-0. On receiving the transmission request, a time-division multivibrator transfers transmitting information equivalent to the transmissiin request on reference to the content of the node channel table. Consequently, the information transfer process can be simplified and a random alternative route can also be secured at need. |
