description ic iThe invention relates to a device for exchanging digital data between several sources and at least one hub in a CDMA system, characterized in that it comprises a number n of digital transmission/reception circuits installed in parallel, each circuit comprising a transmitter comprising means of generating an integer number Nof codes that will be used for spectral spreading of data to be transmitted and a receiver comprising means of detecting the access of new sources to the CDMA system transmission channel and means of generating synchronization signals and power control signals corresponding to each detected new source.
