A fully integrated 'switched star' cabled television system is described, with particular emphasis on the more innovative aspects of the design.
Among the most important factors affecting the design was the need for complete transparency in the distribution of present and likely future wideband services. This dictated that a combination of Space and Frequency Division Multiplex be adopted on the Primary Distribution network. Consequently a hybrid system of matrix crosspoint switches and frequency agile converters in combination is employed at the switchpoint.
