<p>PURPOSE:To avoid the delay difference of a main signal and a control signal by setting two independent pass signals being the main signal and the control signal sent from a terminal equipment through the same path in a network where plural multiplex cross connection devices are interconnected by plural transmission lines. CONSTITUTION:In the case of setting paths for two pass signals being a main signal and a control signal sent from a terminal equipment 6, a start node 1 references an operating band table for the operating band of a connected transmission line and sends a same path retrieval message to an adjacent node having an idle band. Then the transmission of the same path retrieval message and the retrieval of transmission line are implemented among relay nodes 2-4 till the connection to an end node 5 and two independent path signals being the main signal and the control signal are sent through a same path.</p> |
