The standard specifies specific requirements for generic cabling systems, which are used in homes; it is to be used in conjunction with part 1 of the series. It specifies the cabling topology and minimum configuration, implementation options and requirements such as location and density of connection points, in order to support applications covering the area of information, broadcast and communication technologies as well as commands and controls. It deploys both balanced copper cables and coaxial cables. Amendment 2 introduces requirements for optical fibre cabling support within homes. In addition, several editorial improvements have been introduced.
