In a system for transmitting data from a data transmission device to unspecified many data reception devices that make asynchronous connections, the data transmission device carries out the repetitive transmission by repeating the operations of transmitting a prescribed amount of data to be transmitted by applying a prescribed signal conversion and then pausing the signal conversion processing for a prescribed period of time so as to provide a transmission pause state in the transmission signals which is to be utilized as a reception timing at each data repcetion device. At each data reception device, the transmission pause state in the transmission signals are detected at an arbitrary timing, and the reception of the transmission data is started by using the detected transmission pause state as the reception timing.Field of SearchDATA FLOW CONGESTION PREVENTION OR CONTROLControl of data admission to the network Based on data flow rate measurement Flow control of data transmission through a network Transmit/receive interaction control Having a plurality of nodes performing distributed switching Queuing arrangement Having both input and output queuing Store and forward Only active channels transmitted Adaptive selection of channel assignment technique Arbitration for access between contending stations Using weighted back-off timing Having multiple idle or busy signals simultaneously on the network Details of circuit or interface for connecting user to the network Adaptive Assignment of variable bandwidth or time period for transmission or reception Assembly or disassembly of messages having address headers Modems (data sets) Interface attached device (e.g., interface with modem, facsimile, computer, etc.) | |
