<p>PURPOSE:To exchange lines without depending on the synchronization and the transmission speed of a whole network by suppling a reproduced clock to a terminal connected to a node and fixing the synchronization between specified nodes. CONSTITUTION:The node which works as a synchronizing master supplies a base clock to the connected terminal and it provides a base clock generation means 6 which generates the phase information of the base clock as the specified bit of digital information. The node which works as a synchronizing slave actuates with referring the digital phase information received through a network as a control marker and it provides a base clock reproducing means 7 which reproduces the clock synchronously with the base clock. By supplying the reproduced clock to the terminal connected to the node, the synchronization between the specified nodes is made to be fixed. Therefore the lines can be exchanged without depending on the synchronization and the transmission speed of the whole network in a packet multiplex network.</p> |
