Wideband digital signal distribution system

摘要: Wideband digital signals, such as video program are distributed to multiple customer locations by providing the wideband signals all line interface units in an intermediate selection terminal which is remote from a central signal distribution office. The individual made available circuits way of nonreflectively terminated transmission lines and high-input-impedance tapping circuits. Control terminals used at corresponding circuit control channels for use, any number customers being able select simultaneously common one said lines. Other office limit access signals.
