A time-place organization for a digital broad-band telecommunication supply system (optical-fibre)

Describes the principle of a glass-fibre-transmission-channel system capable of carrying simultaneously a wide range of telecommunication services, e.g. colour TV and stereo radio, telephone and 'picture'-phone, pictorial data display. The signals are transmitted digitally with time-multiplexing, requiring 1024*64 kbit/s for colour TV distribution or only 16*64 kbit/s for stereo sound distribution. For 2-way or 'dialogue' services such as the telephone, Telex, facsimile or data services (requiring only 64 kbit/s), a second glass fibre completes the loop from main station to subscriber station and back again. Questions of synchronization and compatibility are also discusssed.
