The Residential Telecommunications Cabling Standard Committee ANSI/TIA/EIA 570-A developed this requirement to accommodate multi-line phone systems on one category 5 UTP, data applications on the second category 5 UTP, external RF signals (CATV) on one RG6 coaxial cable and internally generated modulated signals on the second RG6 cable. This cabling scheme provides flexibility for homeowners to select service providers that use different types of media to deliver their service.
