GENERIC CABLING FOR CUSTOMER PREMISES –

Part 6: Distributed building services
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 11801-6 was prepared by subcommittee 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
ISO/IEC 11801-6 is to be read in conjunction with ISO/IEC 11801-1, which was created to
consolidate general requirements for generic cabling into a single standard which allows the
other standards in the ISO/IEC 11801 series to have a common reference.
This International Standard has been approved by vote of the member bodies, and the voting
results can be obtained from the address given on the second title page.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the ISO/IEC 11801 series, published under the general title Information
technology – Generic cabling for customer premises, can be found on the IEC website.

INTRODUCTION
The importance of cabling infrastructure is similar to that of other fundamental utilities such as
water and energy supply and interruptions to the services provided over that infrastructure
can have a serious impact. A lack of design foresight, the use of inappropriate components,
incorrect installation, poor administration or inadequate support can threaten quality of service
and have commercial consequence for all types of users.
This document specifies generic cabling for distributed building services and can be used
alone or in conjunction with all the premises-specific standards of the ISO/IEC 11801 series.
It has been prepared to reflect the increasing use of generic cabling in support of non-user
specific services and the sharing of information between such services, many of which require
the use of remote powered devices. The distribution of these services is implemented either
as a stand-alone structure and configuration or as an overlay provided to locations other than
those specified by premises-specific standards in the ISO/IEC 11801 series.
This document is not intended to replace the application of other premises-specific standards
in the ISO/IEC 11801 series but has been prepared in recognition of the fact that, although
certain functional elements of distributed building services cabling can be co-located with
those of other generic cabling infrastructures, they can be
a) specified, installed and operated by different entities than those responsible for other
generic cabling infrastructures that are installed within the premises,
b) specified and installed at a different time than other generic cabling infrastructures that
are installed within the premises.
Figure 1 shows the schematic and contextual relationships between the standards relating to
information technology cabling produced by ISO/IEC JTC 1/SC 25, namely the ISO/IEC 11801
series of standards for generic cabling design, standards for the installation, operation and
administration of generic cabling and for testing of installed generic cabling.

Figure 1 – Relationships between the generic cabling
documents produced by ISO/IEC JTC 1/SC 25
The generic cabling specified by this document provides users with
a) an application independent system capable of supporting a wide range of applications in a
range of installation and operating environments,
b) a flexible scheme such that modifications are both easy and economical,
c) a multi-vendor supply chain within an open market for cabling components.
In addition, this document provides
d) relevant industry professionals with guidance allowing the accommodation of cabling
before specific requirements are known, i.e. in the initial planning either for construction or
refurbishment and for further deployment as the requirements of areas are defined,
e) industry and standardization bodies with a cabling system which supports current products
and provides a basis for future product development and applications standardization.
Applications addressed in this document include, but are not limited to those applications in
ISO/IEC 11801:2017, Annex E, as used to support the following services:
1) telecommunications, e.g. wireless access points, distributed antenna systems;
2) energy management, e.g. lighting, power distribution, incoming utility metering;
3) environmental control, e.g. temperature, humidity;
4) personnel management, e.g. access control, cameras, passive infra-red (PIR) detectors,
time and attendance monitoring, electronic signage, audio-visual projectors;
5) personal information and alarms, e.g. paging, patient monitoring, nurse call, infant
security;

---------------------- Page: 9 ----------------------

6) intelligent building systems;
7) communications between devices (i.e. “internet of things”).
Physical layer requirements for the applications listed in ISO/IEC 11801-1:2017, Annex E
have been analysed to determine their compatibility with the cabling performance specified in
this document and, together with statistics concerning premises geography from different
countries and the models described in Clause 6, have been used to develop the requirements
for cabling components and to stipulate their arrangement into cabling systems.
As a result, this document
• specifies a structure for generic cabling supporting a wide variety of applications including,
but not restricted to, the applications in ISO/IEC 11801-1:2017, Annex E,
• adopts balanced cabling channel and link Classes E , F and F , specified in
A A
ISO/IEC 11801-1:2017,
• adopts optical fibre cabling channel and link requirements as specified in
ISO/IEC 11801-1,
• adopts component requirements, specified in ISO/IEC 11801-1, and specifies cabling
implementations that ensure performance of permanent links and of channels that meet or
exceed the requirements of a specified group (e.g. Class) of applications.
Life expectancy of generic cabling systems can vary depending on environmental conditions,
supported applications, aging of materials used in cables, and other factors such as access to
pathways (campus pathways are more difficult to access than building pathways). With
appropriate choice of components, generic cabling systems meeting the requirements of this
document are expected to have a life expectancy of at least ten years.
This document has taken into account requirements specified in application standards listed
in ISO/IEC 11801-1:2017, Annex E. It refers to International Standards for components and
test methods whenever appropriate International Standards are available.
