Abstract

A subscriber premise local bus (SPLB) is connected to a cable drop from a wide-band 2-way network through a gateway device providing frequency conversion and blocking of certain frequencies used in the subscriber premises local bus (SPLB). Service channels to the consumer are provided in a first band such as 54 to 750 MHZ, carried unchanged over the SPLB. Return signals from the subscriber are generated at subscriber devices, such as TV, computers, etc. at, or are up-converted to, signals in a higher frequency band, such as 900 to 950 Mhz, for transmission on the SPLB to the gateway device where they are down-converted to frequencies below 54 Mhz for transmission over the network. A band-pass or other filter may block at least some of the lower frequencies from carrying over from the SPLB to the cable drop or 2-way network.
