ABSTRACT:
A cable television reverse manifold system is coupled between first and second diplexers of off-premises subscriber service providing equipment. The diplexers separate the transmission path between a headend and a subscriber into downstream or forward and upstream or reverse transmission paths. In one embodiment, the reverse manifold apparatus combines signals from at least one subscriber for transmission to the headend. In another embodiment including a data receiver and a controller, the off premises service providing equipment may be controlled by the subscriber. In yet a third embodiment, a radio frequency transmitter is coupled between the controller and the upstream diplexer which may actuate a plurality of simultaneous data transmissions over separate data channels in the notoriously noisy subsplit 5-30 megahertz transmission spectrum.
