Abstract

PURPOSE:To install more terminals economically by connecting a terminal to one subscriber line a branch where data is inserted. CONSTITUTION:Two terminals are connected to one subscriber line of a packet switching network PSN through a data branching and inserting device 4. Assuming that data from a terminal A takes priority to that from a terminal B, the terminal A, when to send the data while the terminal B is sending the data, informs the terminal B to interrupt the data transmission. At this time, data having been sent until the terminal B stops the transmission are stored in the data branching and inserting device 4. The terminal A is connected preferentially to the subscriber line. When the transmission of the terminal A is interrupted, the data of the terminal B being stored are connected to the PSN. Once the data transmission of the terminal A is completed, the terminal B is connected to the PSN.
