This Standard specifies administration systems for commercial telecommunications infrastructure. This infrastructure may range in size from a building requiring a single telecommunications space (TS) and associated elements, to many TSs and associated elements in multiple campus locations. This Standard applies to administration of telecommunications infrastructure in existing, renovated, and new buildings.

Home and building electronic systems (HBES) - Part 8 : conformity assessment of products.
This standard specifies minimum requirements for optical fiber telecommunications cabling components that are used within a commercial building, up to and including the telecommunications outlet/connector, and between buildings in a campus environment. This standard was originally listed for public review in the October 22, 1999 issue of Standards Action. It is being resubmitted due to substantive changes to the text. To obtain an electronic draft: contact Valerie Kamin at Global Engineering Documents at (800) 854-7179.

Class 2 Remote-Control, Signaling, and Power-Limited Circuits
This part of ISO/IEC 14709 defines the requirements for the design and configuration of customer premises cabling for the connection of basic access ISDN equipment. It defines - design requirements for ISDN basic access with point-to-point and point-to-multipoint cabling configurations; - minimum cabling requirements for the installation of new cabling; - criteria for the use of generic cabling; - criteria for the use of existing cabling. This part of ISO/IEC 14709 applies to the customer premises cabling. It describes the cabling requirements, needed to transmit ISDN basic access signals as defined by ITU-T Recommendation 1.430. The requirements placed on the customer premises cabling are solely those necessary to enable terminal equipment conforming to ITU-T Rec. I.430 to operate into the Network Termination (NT) via configurations defined in this part of ISO/IEC 14709. note: 1) Although this part of ISO/IEC 14709 specifies the minimum requirements for cabling dedicated to ISDN basic access, it is highly recommended that cabling newly installed complies with ISO/IEC 11801 class B or higher.
