Abstract
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.

Claim 1
Independent Claim
279 words
Digital data message transmission system between a data transmitter and a data reciever connected by a route transiting through a chain of time division switching networks, said time division switching networks having means for defining recurrent slots grouped in frames and means for connecting incoming slots entering into the switching networks to outgoing slots issuing therefrom, said digital data message transmission system using a number of slots selected by the data transmitter according to the data flow to be transmitted and comprising means situated in the transmitter for cyclic severance of the digital data message into a number of words equal to the selected slot number, means situated in the transmitter and the receiver for successively selecting incoming and outgoing slots in a number equal to said selected slot number and means for respectively assigning said selected incoming and outgoing slots to the words, whereby each word of the digital data message is associated to an incoming slot and to an outgoing slot, means situated in the transmitter for transmitting the words in their associated selected incoming slots, an array of identical reception shift registers situated in the receiver and respectively associated with the wrods, each reception shift register being split up into a number of sections respectively associated with the frames of the selected outgoing slots, means for receiving each given word in its associated reception shift register and in the section thereof associated with the frame during which the selected outgoing slot associated with said given word is received and a synthesis shift register having a number of sections equal to the selected slot number and respectively connected to the last sections of the reception shift registers.
