信息技术.一般的家用敷设电缆

[中文适用范围]： 该国际标准规定了家庭通用布线。 住宅可以包含一栋或多栋建筑物，也可以位于包含多栋住宅的建筑物内。 该标准规定了三组应用的通用布线： •信息和通信技术（ICT）； •广播和通信技术（BCT）； •建筑物内的命令、控制和通信(CCCB)。 它规定了包含以下一项或多项的布线： •平衡布线； •同轴电缆； •光纤布线。 该标准规定了通用布线的设计和配置要求： a) 结构和拓扑； b) 最低配置； c) 永久链路和通道的性能要求； d) 连接点的密度和位置； e) 与专用设备和外部网络的接口； f) 与其他建筑服务共存。 尽管安全（电气、防火等）和电磁兼容性（EMC）要求超出了本国际标准的范围，并由其他标准和法规涵盖，但本国际标准中提供的信息可能有助于满足这些要求。 [外文原描述]： 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.
