Abstract :
This paper presents a review of the main telecommunications systems now under development in France. First, it gives the general objectives, the basic options, and the general design of the new electronic switching system E. 1 defined by CNET, with the principal characteristics of the E.10 and E.12 variants, and general planning of studies and development in process in this field. Then a summary of the new transmission systems under development such as digital systems on cables, radio relays, or circular waveguide, as well as analog systems, including submarine and space systems is given. Finally, some considerations are given to the increasing use of information processing for the telecommunication network, and to the development of specialized networks for new kinds of information.
