Times slot switching

A time slot association device for the establishment of a high quality connection between two subscribers utilizing several time slots within the same frame in a time switching network, said device being designed to associate with each input time slot x of each data storage reserved for said high quality connection an output time slot y from among the available output time slots such that the samples written in the data storages during these input time slots x are read during the output time slots y according to the order in which they were entered, said device including first means for detecting said input time slots x and output time slots y reserved for said high quality connection according to their chronological order within a frame, second means coupled to said first means to increase by one step a binary reference code m when said first means detects an output time slot y and to decrease by one step said binary code when an input time slot x is detected, third means coupled to said second means to identify one of the output time slots y corresponding to the maximum result obtained during the different increasings, and fourth means coupled to said first and third means to associate one of said time slots y corresponding to the maximum result respectively with the immediately preceding input time slot x of the high quality connection.
