This European Standard specifies generic cabling that supports a wide range of communication services within premises that comprise single or multiple buildings on a campus. It addresses the increasing use of generic cabling in support of non-user specific services, many of which require the use of remote powered devices including telecommunications, energy management, environmental control, personnel management, personal information and alarms.The distribution of these services is provided to locations (e.g. for wireless access points, remote powered devices and building management systems) other than those specified in premises-specific standards in EN 50173 series by means of either: a)an overlay structure and configuration to that specified within EN 50173 series, orb)a stand-alone structure and configuration.It covers balanced cabling and optical fibre cabling.This European Standard is based upon and references the requirements of EN 50173 1, and in addition specifies implementation options.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.
