Abstract: A switchable transmission system operating by time-sharing for data carrying digital information, comprises a distant exchange and a local exchange, whereof the timers are not strictly synchronous, and means of correcting the relative drift of these timers. The system employs means for correcting the repetitions or omissions of synchronization words. Means are incorporated in the distant exchange for the transmission of blank words on each transmission line between data-carrying words. The local exchange comprises three shift registers grouped in cascade and chronologically staggered with respect to each other, means for scanning words carrying digital information and for selectively connecting these scanning means to the said registers. The connecting means are controlled by repetitions or omissions of synchronization words, and by the reception of the blank words, in such manner as to make use, as the case may be, of the first or second registers or of the third and first registers, depending on the kind of synchronization error observed.

Abstract: Data transmission system over routes composed of a chain of cascaded time division switching networks and through a number of time slots depending upon the data flow and selected by the data transmitter station. The message data to be transmitted are chopped into as many words as there are transmission time slots. The transmitting routes are defined by the incoming slots in the home time division exchange of the transmitter station and the outgoing slots in the home time division exchange of the receiver station. The slot numbers of the incoming and outgoing slots are stored together with the chronological numbers of establishment of the routes through said slots. Reception of the message words takes place in groups of shift registers whose number is equal to the number of time slots and selectively in a particular shift register of said register groups depending upon the delay encountered in the transmission by the word considered.
