Information technology — Implementation and operation of customer premises cabling — Part 2: Planning and installation
ISO/IEC 14763-2:2019 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: a) specification of the installation; b) quality assurance; c) installation planning; d) installation practice; e) documentation; f) administration; g) testing; h) inspection; i) operation; j) maintenance; k) repair. The requirements and recommendations of Clauses 5 to 14 are premises-independent. Annexes C through G contain premises-specific amendments of and additions to these requirements and recommendations. In addition, this document describes the methodology for the assessment of spaces, pathways, pathway systems and cabling (either installed or planned) in support of remote powering objectives. This document excludes specific requirements applicable to other cabling systems (e.g. power supply cabling); however, it takes account of the effects other cabling systems may have on the installation of telecommunications cabling (and vice versa) and gives general advice. This document excludes those aspects of installation associated with the transmission of signals in free space between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or satellite). This document is applicable to certain hazardous environments but does not exclude additional requirements which are applicable in particular circumstances (e.g. electricity supply and electrified railways). Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations. This second edition includes the following significant technical changes with respect to the previous edition: the inclusion of planning and installation practices to support remote powering over the telecommunications cabling infrastructure and the inclusion of planning and installation practices outside buildings.

FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC National Committees and ISO member bodies.
3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to
ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held
responsible for the way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees and ISO member bodies undertake to
apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and
regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding
national or regional publication should be clearly indicated in the latter.
5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not responsible
for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC National Committees or ISO member bodies for any
personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for
costs (including legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC
publication or any other IEC, ISO or ISO/IEC publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC publication may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 14763-2 was prepared by subcommittee 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
This second edition cancels and replaces the first edition published in 2012 and
Amendment 1:2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• the inclusion of planning and installation practices to support remote powering over the
telecommunications cabling infrastructure;
• the inclusion of planning and installation practices outside buildings.

INTRODUCTION
The use of generic information technology (IT) cabling, termed telecommunications cabling
throughout this document (in accordance with the ISO/IEC 11801 series), for an increased
number of non-IT services is reflected in the predominant use of the term telecommunications
in this document.
The importance of services delivered by telecommunications cabling infrastructure is similar
to that of utilities such as heating, lighting and electricity supplies. As with those utilities,
interruptions to service can have a serious impact. Poor quality of service due to lack of
planning, use of inappropriate components, incorrect installation, poor administration or
inadequate support can threaten an organization’s effectiveness.
There are four phases in the successful implementation of telecommunications cabling:
a) design;
b) specification – the detailed requirement for the cabling, including the planning of its
accommodation and associated building services addressing safety and specific
environments (e.g. electromagnetic), together with the quality assurance requirements to
be applied;
c) installation – in accordance with the requirements of the specification;
d) operation – the management of connectivity and the maintenance of transmission
performance during the life of the cabling.
This document supports the specification, implementation and operation of generic
telecommunications cabling designed in accordance with the standards and associated
documents developed by ISO/IEC JTC 1/SC 25 and addresses the fo
