    摘要： A method is disclosed for establishing connections from subscriber stations or transmission lines connected to a data exchange system to signal converters. The data exchange system receives information concerning the free state or busy state of the signal converters. For this purpose, it is provided that, having forwarded the signals with which it has been previously supplied for signal conversion, the signal converter emits a special free signal which may differ from an accompanying signal indicating the end of signal transmission and which changes the busy state signal ("1") indicative of the busy state of the signal converter directly into a free state signal ("0").

    摘要： The present invention provides a data transmission method for sending parallel data from a transmitting side to a receiving side. After transmitting an i-th item of data (DT.sub.i), the transmitting side sends a high-level data transmission signal (DS) to the receiving side at the expiration of a predetermined period of time (t.sub.1). In response to receipt of the high-level data transmission signal (DS), the receiving side reads the i-th item of data (DT.sub.i) and sends a high-level data reception signal (DR) to the transmitting side. The transmitting side ends the transmission cycle for the i-th item of data upon receiving the high-level data reception signal (DR). After transmitting the next or (i+1)th item of data (DT.sub.i+1), the transmitting side sends a low-level data transmission signal (DS) at the expiration of the predetermined period of time (t.sub.1). In response to receipt of the low-level data transmission signal (DS), the receiving side reads the (i+1)th item of data (DT.sub.i+1) and sends a low-level data reception signal (DR) to the transmitting side. The transmitting side ends the transmission cycle for the (i+1)th item of data upon receiving the low-level data reception signal (DR). In subsequent data transmission, data are successively transmitted by repeating th i-th and (i+1)th data transmission cycles.

    摘要： A communication network comprising a central station and a plurality of communication response units establishes communication therebetween when the central station transmits a reset pulse followed by a particular unit address and an interrogating code (read function code) to the response units. This initiates a ''''communication cycle'''' during which the central station communicates with a particular response unit. Each response unit has storage elements which are set in a ready-toreceive state by the reset pulse. The addressed response unit responds with either a data signal carrying the unit address and data information for the central station or an idle signal carrying the unit address and indicating no data. The central station includes an element which is able to distinguish between the two signals. Upon receiving a data signal from the response unit, the central station checks the received signal for correctness and clears that response unit by transmitting an initial reset pulse followed by the same unit address and a clear function code which empties the addressed unit of the data stored therein. When the idle signal is received, the central station simply initiates another communication cycle with another response unit. When the central station determines that there is an error in transmission or a mismatch between the transmitted and received unit address, the reset pulse, unit address, and read function code are retransmitted to the same response unit. When there is a second occurrence of error or mismatch, the reset pulse, the unit address, and an error function code are transmitted and a new communication cycle is initiated with another response unit.
