ISO/IEC 10192-1:2002

Information technology - Home electronic system (HES) interfaces - Part 1: Universal Interface (UI) Class 1

This is one of a set of standards describing the characteristics of a specific home control system called the Home Electronic System, HES. It specifies the characteristics of the Universal Interface (UI) Class 1 that connects devices to the home network in an HES for control applications; it informs as to the usefulness of the principles of a UI and forms a basis for new work in this field. This standard specifies a generic interface for a device to connect to a home control network via a Network Adaptor Unit. The home control network signals may be carried on the cabling system being specified in ISO/IEC 15018 (Information technology - Integrated cabling for residential and SOHO (Small Office, Home Office) environments -- under development).

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 JTC1.
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.
The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC)
draw attention to the fact that the European Patent EP PS 0 344 609 B1 “Digital signal transmission system for
domestic application” may be needed to implement this International Standard.
ISO and IEC take no position concerning the evidence, validity and scope of patent rights. The European Patent
EP PS 0 344 609 B1 is held by Gebrüder Merten GmbH & Co. KG. Gebrüder Merten GmbH & Co. KG are willing to
negotiate licenses under reasonable and non-discriminatory terms and conditions with applicants throughout the
world. In this respect the statement of the holder of the patent rights is registered with the ISO and IEC. Information
may be obtained from:
Gebrüder Merten GmbH & Co. KG

Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights other than those identified above. ISO and IEC shall not be held responsible for identifying any or all
such patent rights.
International Standard ISO/IEC 10192-1 was prepared by subcommittee 25: Interconnection of
information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
This publication has been drafted in accordance with the ISO/IEC directives, part 2.
Annexes A and B are for information only.
