Abstract: PURPOSE: To connect a first and a second multiple node communication routes in which each allocation and assignment system is used with a bridge node and to provide a method and a device to enable to access the route by the node on the route. CONSTITUTION: The access to a second route is controlled by a second signal to transmit information directed to the first route to the bridge node 16 by propagating the first allocation and assignment signal on the first route and propagating a second allocation and assignment signal on the second route. The allocation and assignment signal is synchronized so as to assure that the second signal circulates only once by every time the first signal circulates. When the bridge node is full, the information from the first route to the second route is deviated around the first route from the bridge node.
