A countrywide radio link system is under installation. The system will carry TV and sound programs to transmitters, together with program circuits and communication between the Broadcasting Center and regional studios. Sound program distribution is relayed over five time-multiplexed PCM channels above the TV picture (SOV). Sound program exchange circuits, local transmitter feed circuits, and communication are relayed as an 8448 kbit/s time-multiplexed PCM signal in the baseband of an ordinary 960-channel telephone link, giving in total 15 music channels and 30 telephone channels. System and equipment are described. Future extensions and switching facilities are discussed.
