Abstract
Data communication through a composite network constituted by a plurality of mutually connected individual networks. When a center connected to a first network such as a wide-area telephone network and DDX for collecting information such as maintenance/management information performs data communication with a plurality of work stations connected to a network such as LAN, the information collecting center transmits a composite command containing collectively assembled addresses of the object work stations and operation commands to these stations. The composite command is disassembled in the second network. According to one method, the command is executed by the relevant work station upon reception of the composite command which is subsequently transferred to the succeeding station.
