PURPOSE:To attain connection between two network systems without the provision of a complicated line control section by providing a connection/disconnection control section connecting and disconnecting transmission lines between both the systems mutually. CONSTITUTION:The network systems 20A, 20B consist respectively of host stations 21A, 21B, plural work stations 22A1-22An, 22B1-22Bn and connection/ disconnection control sections 24A, 24B connecting and disconnecting transmission lines 23A, 23B. In connecting both the networks, one acts as a host station of the entire network system and the other functions as a work station only for the connecting period. As the method connecting and disconnecting both the networks, a method predetermining the connecting time or a method where the start of connection is ordered in advance by other communication line is considered. |
