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