This satellite centre includes subscriber access circuits (1) produced in electronics technology, which particularly carry out the functions of: translation of the cell headers; addition of a routing label; and policing throughput monitoring. It further includes concentrators (2) including statistical time-division multiplexing devices (34.1, ..., 34.16) and periodic time-division demultiplexing devices (47.1, ..., 47.16) which are produced in electronics technology; and a spectral multiplexing and data rate-changing device (38), a periodic time-division multiplexing device without spectral multiplexing (40), a data rate changing and spectral demultiplexing device (43), and a periodic time-division demultiplexing and spectral multiplexing device (41), which are produced in optical technology. This structure makes it possible to optimise the use of the optical technology and of the electronics technology in order to obtain minimum production costs.
