Abstract

A communication system is coupled to a cable television network wherein cable television signals, data signals and telephonic signals are transmitted on the coaxial cable infrastructure. To facilitate the simultaneous transmission of cable signals, data signals and telephonic signals, a frequency spectrum is defined for a coaxial cable network in which a band of frequencies for carrying telephonic signals is interposed in the cable television signals bands of frequencies. In a coaxial cable system capable of carrying signals up to 1 megahertz in frequency, a total of 5 frequency bands are defined. Within the frequency band for carrying telephonic signals, signals from a PCS system or the like as well as signals from other telecommunication devices, one system, such as SMS centers, base stations and mobile switching centers may be transmitted. Additionally, television channels may also be transmitted in this frequency band if the beginning of the frequency is at a frequency channel for carrying a cable television channel. A method includes transmitting the various types of signals within the specified frequency bands.
