44、SI/BICSI 001-2009) Due to the life, health and safety aspects of educational facilities, there may be a substantial number of authorities having jurisdiction (AHJs). Designers and installers are encouraged to thoroughly research the requirements established by these AHJs. Useful supplements to this

45、Standard are the most current revisions of the following BICSI doc-uments: Telecommunications Distribution Methods Manual, Outside Plant Design Reference ANSI/TIA-4966 vii Manual, and Information Technology Systems Installation Methods Manual. These manuals provide practices and methods by which man

46、y of the requirements of this Standard are imple-mented. Other references are listed in Annex B. Annexes There are two annexes to this Standard. Annexes A and B are informative and not considered requirements of this Standard. Introduction This Standard specifies a telecommunications cabling system

47、for educational buildings and spaces that will support a multi-product, multi-vendor environment. It also provides information that may be used for the design of telecommunications products for these enterprises. Purpose The purpose of this Standard is to enable the planning and installation of a st

48、ructured cabling system for educational buildings and spaces. Installation of cabling systems during building construction or renovation is typically easier and less disruptive than after the building is occu-pied. This applies, in particular, to operating facilities that will have additional restri

49、ctions on ac-cess to spaces and areas after occupancy. Selection of media and network design is of particu-lar importance for larger educational facilities, which may have a useful life far longer than tradi-tional office-oriented commercial buildings. This Standard establishes performance and technical criteria for various cabling system configu-rations for accessing and connecting their respective elements. In order to determine the re-quirements of a generic cabling system, performance requirements for vari
