Abstract

A system for distributing remote telephone traffic between a base station and remote antenna site is disclosed. The base station and remote antenna sites are connected via a cable television network. The base station receives from a public telephone network parallel channels of outbound voice signals for radio telephones operating within the cellular areas of the remote antenna sites. The base station will digitize and time compress each of these outbound telephone signals, and insert them in a transmit frame. The transmit frame is modulated on a subcarrier and applied to the cable television network. A plurality of remote sites are connected to the cable television network and receive and rebroadcast digitized voice signals to radio telephones operating within their cellular areas. Inbound serial channel data received from a radio telephone is inserted in a serial receive data frame. A second subcarrier is modulated with the receive data frame and applied to the cable television network for transmission upstream to the base station. The base station will demodulate the inbound receive frame and apply the digitized voice signals to the public telephone network to complete a telephone communication link.
