Telecommunications installations — Telecommunications pathways and spaces for commercial buildings

Included in Key Standards supporting Generic Cabling in all premises types
This Standard provides specific guidance to architects, planners, designers, engineers, builders, installers, maintenance personnel, building owners, managers and users in the planning and installation of physical pathways and spaces in and between buildings to accommodate the equipment and cabling infrastructure necessary for communications; to the extent that this is not adequately covered for Australian and New Zealand purposes in AS/NZSISO/IEC 14763.2:2014.
