Title: Data transmission systems
IPC: H04L1/18
Filed: 1975-09-24
Abstract: 1522015 Data transmission SIEMENS AG 24 Sept 1975 [27 Sept 1974] 39064/75 Heading H4P A data transmission system includes two stations each having a receiver and a transmitter interconnected via a two-way transmission channel. Each station includes ARQ error correction facilities and its associated receiver includes a repetition counter which blocks data output during each repetition cycle, whilst its transmitter includes a repetition counter which blocks call-up of data during each repetition cycle and requests or effects repetition from or to the receiver in another station by effecting a repetition of the last items of data to be transmitted and intermediately stored, the transmitter being arranged to preface each repetition with an RQ signal indicative of the repetition and each receiver repetition counter being responsive to the RQ signal only when in a rest state. Each station also provides respective character timing pulses for its transmitter and its receiver and a phasing circuit for shifting the character timing pulse train frame of the receiver element by element until character synchronism is obtained, Each station further includes a coupling circuit connected between its repetition counters, this circuit being arranged to be enabled by the phasing circuit only diring a phasing-in procedure in such manner that following each start of the repetition counter of the transmitter it sets the repetition counter of the receiver into a predetermined counting state so that the receiver repetition counter will reach its rest state at such a time that the receiver repetition counter will not be able to respond to the next received RQ signal resulting from repetition by the transmitter in the same station. This arrangement ensures that the repetition counters, after phasing-in procedures, are so related in terms of time that the repetitions clear themselves, thus resulting in satisfactory operation directly following phasing-in procedures.
