The service center is the central hub where all cables originate and are run throughout the home. The service center contains modules designed to handle specific needs like video and audio distribution, multiple telephone lines, Internet access, and computer networking. The service center allows all wiring to be installed in what's called a star configuration with home runs to all outlets. A star-wired system is the most flexible and most reliable system available today. In fact, most businesses use the same type of system for their telephone and networking needs.

It should be centrally located in the home in a place that is easy to access. The service or distribution center allows the wiring system to be customized and evolved as new technologies are developed. It provides universal access to various networking elements within the home as well as connectivity to service providers.
