Their basic principles, however, are app

In order to point out the commonalities of these cabling design standards, these EN are published as individua

17、l parts of the series EN 50173, thus also acknowledging that standards users recognize the designation “EN 50173” as a synonym for generic cabling design.

33、pplies. As with other utilities, interruptions to service can have serious impact. Poor quality of service due to lack of planning, use of inappropriate components, incorrect installation, poor administration or inadequate support can threaten an organisations effectiveness. Historically, the cablin

34、g within premises comprised both application-specific and multipurpose networks. Standards within the EN 50173 series have enabled a controlled migration to generic cabling (with an associated reduction in the use of application-specific cabling) and supported the development of high data rate appli

35、cations based upon defined cabling models. This European Standard, EN 50173-2, has been prepared to reflect the demands of generic cabling within office premises and provides: a) users with an application independent generic cabling system and an open market for cabling components; b) users with a f

36、lexible cabling scheme such that modifications are both easy and economical; c) building professionals (for example, architects) with guidance allowing the accommodation of cabling before specific requirements are known; i.e., in the initial planning either for construction or refurbishment; d) indu

37、stry and standardisation bodies with a cabling system which supports current products and provides a basis for future product development and applications standardisation. This European Standard specifies multi-vendor cabling, and is related to: - the associated standard covering general requirement

38、s for generic cabling within premises (EN 50173-1); - standards for cabling components developed by Technical Committees of CENELEC and/or IEC; - standards for the quality assurance and installation of information technology cabling (series EN 50174) and testing of installed cabling (EN 50346); - ap

39、plications developed by the technical bodies of IEC (including the subcommittees of ISO/IEC JTC 1) and study groups of ITU-T. The applications listed in EN 50173-1:2011, Annex F, have been analysed to determine the requirements for a generic cabling system. These requirements, together with statisti

40、cs concerning premises geography from different countries and the models described in Clause 6, have been used to develop the requirements for cabling components and to stipulate their arrangement into cabling systems. As a result, generic cabling defined within this European Standard is targeted at

41、, but not limited to, office premises. It is anticipated that the generic cabling system meeting the minimum requirements of this European Standard will have a life expectancy in excess of ten years. !“BS EN 50173-2:2007+A1:2010EN 50173-2:2007+A1:2010 (E) 5 Figure 1 and Table 1 show the schematic an
