6、stration A.1 General Four typical classes of administration are specified in this Annex to accommodate various degrees of complexity related to the telecommunications infrastructure. A.2 Determination of class A.2.1 General The most relevant factors in determining the minimum class of administration

7、 are the size and complexity of the infrastructure. The number of telecommunications spaces, such as equipment rooms, common equipment rooms, telecommunications rooms, common telecommunications rooms and entrance facility spaces, is an indicator of the degree of complexity. Classes are scalable and

8、allow expansion without requiring changes to existing identifiers or labels. For mission critical systems, buildings over 7 000 m2or multi-tenant buildings, administration of pathways and spaces, and outside plant elements is strongly recommended. A.2.2 Class 1 Class 1 addresses the administration n

The latter is the only telecommunication space administered whereas there are no telecommunications rooms and no backbone cabling or outside plant cabling systems to administer. Simple cable pathways will generally be intuitively understoo

10、d and need not be administered. In order to administer cable pathways or fire-stopping locations, class 2 or higher administration systems should be used. Class 1 will typically be managed using a paper-based system or with general purpose spreadsheet software. A.2.3 Class 2 Class 2 administration p

11、rovides for the telecommunications infrastructure administration needs of a single building or of a tenant that is served by a single or multiple telecommunications spaces (e.g., an equipment room with one or more telecommunications rooms) within a single building. Class 2 administration includes al

12、l elements of class 1 administration, plus identifiers for backbone cabling, multiple-element grounding and bonding systems, and fire-stopping. Cable pathways may be intuitively understood, administration of these elements is therefore optional. Class 2 may be managed using a paper-based system, gen

A.2.4 Class 3 Class 3 administration addresses the needs of a campus, including its buildings and outside plant elements. Class 3 administration includes all elements of class 2 administration, plus identifiers for buil

Class 3 may be managed with a paper-based 4 14763-1 Amend.1 ISO/IEC:2004(E) system, general purpose spreadsheet software or special-purpose cable management software. A.2.5 Class 4 Cl

Class 4 administration includes all elements of class 3 administration, plus an identifier for each site, and optional identifiers for inter-campus elements, such as wide area network connections.
