PCM Programme Transmission and Communication Network for the Norwegian Broadcasting Corporation
A country-wide radio link system is under installation. The system will carry TV and sound program to transmitters, together with program circuits and communication between the Broadcasting center and regional studios. Sound program distribution is relayed over 5 time-multiplexed PCM channels above the TV-picture (SOV). Sound program exchange circuits, local transmitter feed circuits and communication is relayed as an 8.448 Mbit/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 is described. Future extensions and switching facilities are discussed.
