Posted by on May 13, 2020 in Uncategorized | 0 comments

From 24 to 28 February 2020, JTC 1/SC 25 WG 3 “Customer Premises Cabling” held its 68th meeting, hosted by Standards Australia in Sydney. Some 30 delegates worked through an impressive agenda, the highlights of which are summarized below:

A new work item was approved on

ISO/IEC 14763-5 Information technology – Implementation and operation of customer premises cabling – Part 5 Sustainability

Focusing on environmental sustainability, it is widely recognized that IT cabling systems conforming with ISO/IEC 11801 standards are intended to provide the user with extended life expectancy. Sustainability further requires the reduction of the impacts with regard to material usage and on long-term use of the cabling infrastructure. In keeping with this, and the spirit of the United Nations Sustainable Development Goals, the ISO/IEC undertakes this new international standard.

This standard seeks to maximize the user benefits from sustainability of IT cabling systems in the building space by  addressing design, selection, packaging and transportation of components, system operation and maintenance, treatment of waste materials, and skillsets necessary for designers, installers and users. It is especially import to ensure the education of a new generation of cabling technologists across the industry.

ISO/IEC 11801 series to include single pair cabling

ISO/IEC 11801 series is currently being amended to cover “balanced single pair cabling systems” which will expand the range of use for structured cabling systems. With the capability of delivering data and power starting from 15 m reach up to 1000 m reach. These systems are ideally suited for incorporating IoT devices into premises cabling systems. Single Pair applications are increasingly important for all operators of automation networks in buildings and industrial areas. Implementing these new single pair cabling structures provides for application of device level diagnostics and security and provides for improved system scalability.

Single-pair cabling is not meant to replace traditional four-pair cabling, but support emerging applications, such as interconnecting IoT and M2M devices. When deployed in support of appropriate applications, single-pair applications provide significant economic, density, sustainability, and installation advantages. Some examples of single pair use cases include:

  • Building automation systems
  • Lighting systems
  • Elevator and escalator control systems
  • Access control systems
  • Security and fire alarm systems
  • Industrial automation, robotics and process control (IIoT)

ISO/IEC 14763-2, Information technology – implementation and operation of customer premises cabling – Part 2: Planning and installation

At the end of 2019, the 2nd edition of ISO/IEC 14763-2 has been published. This standard specifies requirements for the planning, installation and operation of telecommunications cabling and cabling infrastructures including cabling, pathways, spaces and telecommunications bonds (other than that specified in ISO/IEC 30129) in support of generic cabling standards and associated documents.

The following aspects are addressed: specification of the installation; quality assurance; installation planning; installation practice; documentation; administration; testing; inspection; operation; maintenance; repair.

The 2nd edition includes the following significant technical changes with respect to the previous edition:

  1. the inclusion of planning and installation practices to support remote powering over the telecommunications cabling infrastructure;
  2. the inclusion of planning and installation practices outside buildings.
