FOREWORD
1) ISO (International Organization for Standardization) and IEC (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. Their preparation is entrusted to technical
committees; any ISO and IEC member body interested in the subject dealt with may participate in this
preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC
also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to
national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the
national bodies casting a vote.
3) 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 and ISO member bodies.
4) IEC, ISO and ISO/IEC Publications have the form of recommendations for international use and are accepted
by IEC 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.
5) In order to promote international uniformity, IEC 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 Publication and the corresponding national or regional publication should
be clearly indicated in the latter.
6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for
any equipment declared to be in conformity with an ISO/IEC Publication.
7) All users should ensure that they have the latest edition of this publication.
8) 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 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.
9) 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.
IEC and ISO draw attention to the fact that it is claimed that compliance with this document may involve the use of
a patent primarily concerning activities as described in clause 5: Requirements for HES Class 1, Twisted Pair
Type 0 (TP0).
Schneider Electric Industries SAS has informed IEC and ISO that they have the patent applications or granted
patents as listed below:
EP 0370 921 B1, EP 0911 777 A1.

INTRODUCTION
The reference model for Open System Interconnection (OSI), specified in ISO/IEC 7498,
assigns the functions that are needed for communications between two entities that are
connected by medium to seven logical layers. This International Standard specifies
interconnection of entities used for home and building control via the medium twisted pair. It
specifies the medium and medium dependent functions such as the cable, the connectors and
the transmission technology in terms of the Physical Layer and the Data Link Layer according
to ISO/IEC 7498.
Currently, ISO/IEC 14543, Information technology – Home Electronic System (HES)
architecture, consists of the following parts:
Part 2-1: Introduction and device modularity
Part 3-1: Communication layers – Application layer for network based control of HES Class 1
Part 3-2: Communication layers – Transport, network and general parts of data link layer for
network based control of HES Class 1
Part 3-3: User process for network based control of HES Class 1
Part 3-4: System management – Management procedures for network based control of HES
Class 1
Part 3-5: Media and media dependent layers – Powerline for network based control of HES
Class 1
Part 3-6: Media and media dependent layers – Twisted pair for network based control of
HES Class 1
Part 3-7: Media and media dependent layers – Radio frequency for network based control of
HES Class 1
Part 4: Home and building automation in a mixed-use building (technical report)
Part 5-1: Intelligent grouping and resource sharing for HES Class 2 and Class 3 – Core
protocol (under consideration)
Part 5-2: Intelligent grouping and resource sharing for HES Class 2 and Class 3 – Device
