Gone are the days of a few phone jacks and a cable wire pulled through a wall. Modern home offices and TV systems require integration. As a result, wiring cable, phone, and internet networks has become a specialized field. The problem is that a telephone technician is just that, a telephone technician. He is trained in his field of expertise. The cable person only knows cable. Electricians are qualified to install and repair any type of wire, including TV, phone, and cable.
Many times homeowners make the mistake of paying a telephone technician to run additional phone wire, a cable technician to run the cable and networking lines. Each technician will usually charge service fee just to show up, and then a couple of hours to run the lines.
