We'll show you how to run the wires, install the proper jacks and hook up the central distribution box. The new system doesn't mean you have to scrap your old cables and jacks. Existing phone lines and jacks can coexist with your new system. We recommend that you initially install new cables and jacks to rooms only where they're needed, and upgrade the system with new jacks and lines as your electronic needs change. The beauty of the installation system shown in this article is that it will be easy to reconfigure, enhance or expand it in the future. Eventually you'll be able to connect any compatible devices simply by "jumping" cable or phone lines in the distribution box (much like old-time telephone operators used to do in the first half of this century).
