ABSTRACT:
In addition to five basic operation modes including “Add” operation mode, “Continue” operation mode, “Drop” operation mode, “Split and Add” operation mode and “Drop and Continue” operation mode, a function of carrying out “Time Division Switch Over” operation mode for sequentially switching over these basic operation modes in time division manner every constant time is provided in each of nodes1to8. In a connection for a one-to-multiple communication, a connection for distributing a signal from the node1to a plurality of nodes3, 5and7is set by using “Split and Add” operation mode and “Drop and Continue” operation mode. In a connection for a multiple-to-one communication, the multiple-to-one communication is realized by timely switching between nodes performing one-to-one communication by using “Time Division Switch Over” operation mode for switching over between “Add” operation mode and “Continue” operation mode and “Time Division Switch Over” operation mode for switching over outgoing lines.
