抄録

600Mbit/s circuit switching system which provides mainly the moving-picture service is proposed. This system exchnges digitized NTSC and HDTV signals and integrates the end-to-end communication, center-to-end communication and video distribution services. The communication service or distribution service is selected by the layer three signaling of the I interface. Video channels are switched by control of the higher layer of the subscriber signaling. This system is suitable for a building block architecture. The core module accommodatesfrom tens up to about three hundred subscribers. All of the modules have load and function shared control and standalone functions such as subscriber access, trunk access,inter-office signalingand system management.
