Specifies the requirements for designing and configuring customer premises cabling for the connection of basic access ISDN equipment. Includes: 1. Design requirements for ISDN basic access with point-to-multipoint cabling configurations 2. Minimum cabling requirements for the installation of new cabling. 3. Criteria for generic cabling use 4. Criteria for existing cabling Applicable to the customer premises cabling and describes cabling requirements need to transmit ISDN basic access signals as specified by ITU-T Rec. I.430.

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;¹⁾

• 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 I.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.
