TERMINOLOGY FOR THE HOME ELECTRONIC SYSTEM (HES)
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 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.
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) Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC and ISO technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
report of one of the following types:
• type 1, when the required support cannot be obtained for the publication of an
International Standard, despite repeated efforts;
• type 2, when the subject is still under technical development or where, for any other
reason, there is the future but not immediate possibility of an agreement on an
International Standard;
• type 3, when the technical committee has collected data of a different kind from that which
is normally published as an International Standard, for example ‘state of the art’.
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transformed into International Standards. Technical reports of
type 3 do not necessarily have to be reviewed until the data they provide are considered to be
no longer valid or useful.
ISO/IEC 15044, which is a technical report of type 2, was prepared by subcommittee 25:
Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:
Information technology.
International Standards are drafted in accordance with ISO/IEC directives, Part 3.
This document is issued in the type 2 technical report series of publications (according to
15.2.2 of the Procedures for the technical work of ISO/IEC JTC 1 (1998)) as a prospective
standard for provisional application in the field of the Home Electronic System (HES),
because there is an urgent requirement for guidance on how standards in this field should be
understood.
This document is not to be regarded as an International Standard. It is proposed for
provisional application so that information and experience of its use in practice may be
gathered. Comments on the content of this document should be sent to the IEC Central
Office.
A review of this type 2 technical report will be carried out not later than three years after its
publication with the option of extension for a further three years or conversion either to an
International Standard or withdrawal.

INFORMATION TECHNOLOGY –
TERMINOLOGY FOR THE HOME ELECTRONIC SYSTEM (HES)
1 Scope
The home electronic system (HES) provides a common method for interfacing equipment with
a variety of home control systems (HCS) such as sensors, actuators, appliances, user
interfaces, controllers, switches etc. An HCS is a local area network specialized for residential
communications, commonly called home automation.
This terminology is applicable to all standards and technical reports dealing with HES.
2 Terminology
2.1
application
field of use of an HES. An HES may support more than one application
2.2
application object
an HES object located within the HES device application process
2.3
application process
an element within an HES which performs the information processing for a particular
application
2.4
application protocol
standardized protocol for the exchange of information between application processes in an
HES. It is transported without interpretation by the home network resources
2.5
architecture
conceptual structure of systems that are to communicate with each other
2.6
bridge
functional unit interconnecting two home network systems that use the same network layer
protocol but where there may be some differences in the link layer protocol
2.7
classes of home control systems
characterization of home control systems based on their transport capabilities
2.8
connection
association established between two peer entities across a network (or part of a network) for
the purpose of communication between the entities. The association is explicitly established
at some point in time, and exists until explicitly ended

2.9
connection-mode service
service providing communication between two entities within the context of a connection
established between the entities
2.10
connectionless-mode service
service providing communication between two entities not within the context of a connection
established between the entities
2.11

any device with the capability of controlling and possibly monitoring other devices
2.13
device
physical implementation of functions belonging to one or more functional groupings providing
a service directly for an end-user
2.14
device application process
element within a device that performs information processing for a particular application.
Device application processes can represent manual, automated, computerized or physical
processes
2.15
domain
range of validity
NOTE When used for a specific concept, the exact domain should be stated, for example application domain, user
domain.
2.16
end user
entity outside the home control system domain that uses the services and functions of the
home control system
2.17
flow control
function that controls the flow of data within a layer. It regulates the rate at which information
is exchanged between peer entities
2.18
functional grouping
set of functions performing part of the operations of a home control system
NOTE The functions in a functional grouping might be performed in one or more pieces of equipment and the
functions of several functional groupings might be performed in one piece of equipment.
2.19
gateway
unit connecting different networks or parts of one network and performing any necessary
protocol translation

2.20
HES device application process
that part of a device application process that is accessible through the HES communication
network. An HES device application process is built up from application objects. The
functionality of the HES device application process is defined in this series of standard or in
appropriate product standards
2.21
HES home network
home network supporting and including Universal Interfaces
2.22
home control system
home network together with all the devices attached to it, including the rules for control,
communication and management among application processes. Three classes of home
control systems are defined
2.23
home control system class 1
home control system with transport capabilities for telecontrol applications such as:
– control
– monitoring
– measurement
–alarm
– low-speed data transfer
NOTE These capabilities are typically provided by:
– single packet-mode low bandwidth channel
– digital transmission.
2.24
home control system class 2
home control system with class 1 transport capabilities plus:
– switched voice or other information transfer of similar bandwidth
NOTE These capabilities are typically provided by a class 1 system enhanced with:
– multiple switched medium bandwidth channels
– analogue or digital transmission or both
In principle all class 2 capabilities can be supported on a single class 2 channel. For practical reasons however,
class 2 home control systems may contain a separate channel or use a separate medium to support class 1
capabilities.
2.25
home control system class 3
home control system with class 2 transport capabilities plus:
– switched high quality sound and video transfer and high speed data transfer
NOTE These capabilities are typically provided by a class 2 system enhanced with:
– multiple switched high bandwidth channels
– analogue or digital transmission or both
In principle all class 3 capabilities can be supported on a single class 3 channel. For practical reasons however,
class 3 home control systems may contain separate channels or use separate media to support class 1 and 2
capabilities.
2.26
home electronic system, HES
a home control system that conforms to the HES standards. There are three classes of HESs
corresponding to the classes of home control systems
