This European Standard specifies generic cabling in homes, installed to support one or more of the following groups of applications and based upon balanced, coaxial and optical fibre cabling as appropriate: This standard specifies a generic cabling for three groups of applications in homes: Information and Communications Technologies (ICT), Broadcast and Communications Technologies (BCT), and Commands, Controls and Communications in Buildings (CCCB). It is intended to guide installations in new buildings or refurbishments, and also applies where cabling is installed to support only one or two of the three application groups listed above. A generic cabling infrastructure is specified based upon balanced cabling and / or coaxial cabling. ICT channels specified in this standard include optical fibre, but the wider use of fibre optical cabling in a home is for further study. The three groups of applications may also be supported by different types of cabling, which may be subject to other standards. For example, ISO/IEC 11801 specifies generic cabling for ICT applications in general for the office environment. While the cabling structure and reference implementations are matched to the home environment in this standard, the channel performances specified for ICT are identical to those specified in ISO/IEC 11801. Because this standard is designed to cover the three major groups, the cabling system may be installed prior to the selection of specific applications. The home may contain one or more buildings (e.g. farm) or may be within a building which contains more than one home (e.g. one home in a multi-dwelling building). The campus or backbone cabling connecting individual homes is built according to the relevant standard (for instance ISO/IEC 11801, IEC 60728). Generic cabling realised according to this standard: a) allows deployment of a wide range of applications without changes to the fixed cabling infrastructure; b) provides a platform to support moves, adds and changes of connectivity. This standard provides users with an application-independent generic cabling for applications run in homes, and a flexible cabling scheme such that changes are both easy and economical; it provides building professionals (for example, architects) with guidance for accommodating cabling before specific requirements are known, i.e. in the initial planning either for construction or refurbishment; and gives users, designers, and manufacturers of application-specific cabling systems advice on interfacing. It specifies relevant requirements for suppliers of cabling components and installers of cabling, and a distribution system for service providers' services. It supports current products and provides a basis for future product development in home electronic systems. This European standard specifies generic cabling in homes, installed to support one or more of the following groups of applications and based upon balanced and coaxial cabling as appropriate: 1) Information and Communications Technologies (ICT); 2) Broadcast and Communications Technologies (BCT); 3) Commands, Controls and Communications in Buildings (CCCB). A home may contain one or more buildings or may be within a building that contains more than one home. This standard is based upon and references the requirements of EN 50173-1. In addition to the requirements of EN 50173-1, this European Standard specifies the following aspects of generic home cabling: a) structure and topology; b) minimum configuration; c) performance requirements for permanent links and channels1); d) density and location of connection points; e) interfaces to application-specific equipment and external networks; f) coexistence with other building services. Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting these standards and regulations. NOTE 1 – National regulations and local codes may preclude carrying certain services on the cabling specified in this standard. NOTE 2 – Test requirements in this standard are for system designers. NOTE 3 – The installation tests should be decided between supplier and customer or according to the relevant installation guide. NOTE 4 – Audio/video applications are traditionally supported by application-specific cabling implemented with cabling systems based on EN 50083 (see Annex D). Such cabling systems may co-exist with generic cabling specified by this European Standard.
