<p><P>PROBLEM TO BE SOLVED: To provide a synchronous network establishing method and apparatus therefor, capable of establishing network synchronization by cascade-connecting a network of either a first system or a second system, to a node apparatus of either a second system or a first system. <P>SOLUTION: The synchronous network establishing method is provided for a network, having node apparatuses of the first system and the second system in a mixed manner, in which synchronous state indication codes, used in establishing the synchronous network, are mutually different. By establishing the synchronous network, after converting the synchronous state indication code supplied from a neighboring node apparatus of different system into the synchronous state indication code used in the own apparatus system, it becomes possible to establish the network synchronization, by cascade-connecting the network of either the first system or the second system to the node apparatus of either the second system or the first system. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
