ABSTRACT OF THE DISCLOSURE It is the object of the present invention to provide service for a group of subscribers having a particular interest in digital transmission, without cancelling the conventional substantially analogue telephone network. According to the present invention the subscriber group is provided with digital subscriber stations connected to digital terminal exchanges which, for con- nections to be set up beyond the range of the terminal exchange area, are adapted to be selectively connectable with the convention- al analogue network either through digital/analogue converters and analogue/digital converters, or through a new digital long distance network which is connectable with the analogue network through the digital/analogue and analogue/digital converters. The invention can be used in the transmission of speech, music, textcopy, images or data.
