<p>PURPOSE:To standardize a module interface by forming plural service offer means, a video distribution means and a relay connection means as modules and providing a routing switch module applying the communication system service between plural subscriber accommodate modules corresponding to the service offer means between the relay connection means. CONSTITUTION:It is possible for the individual use of a subscriber accommodate module 3, but it is extended in matching with the increase in the subscriber number to be accommodated and a video distribution module 4 is connected thereto, which distributes the video source for video distribution system service offer to plural subscriber accommodate modules 3. Moreover, the function load decentralizing constitution is formed, which able to connect the routing switch module 5, the relay line accommodate module 6 or the like for the communication system service offer. Thus, it is possible for the subscriber to receive the communication system service and the video distribution system service with the same video terminal equipment, and in matching with the requirement at system constitution, required modules are combined to build up the optimum system in terms of building blocks.</p> |
