Foreword

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 3.

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.

Attention is drawn to the possibility that some of the elements of this International Standard 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 13642 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information exchange between systems, in collaboration with ITU-T. The identical text is published as ITU-T Recommendation X.281.

This second edition cancels and replaces the first edition (ISO/IEC 13642:1996), which has been technically revised.

Annex A forms a normative part of this International Standard. Annexes B and C are for information only.

1 Scope

This Recommendation | International Standard provides the specification of management information within an Open System related to those operations of the OSI Physical Layer specified by the specifications in this Recommendation | International Standard. Specifics on how Physical Layer management is accomplished is beyond the scope of this Recommendation | International Standard. Physical Layer management is defined by specifying:

• the managed object class definition of Physical Layer Managed Objects following guidelines put forth by the Structure of Management Information (see ITU-T Recs. X.720 | ISO/IEC 10165-1 to X.723 | ISO/IEC 10165-5;
• the relationship of the Managed Objects and attributes to both the operation of the layer and to other objects and attributes of the layer; and
• the action type operations on the attributes of Physical Layer Managed Objects that are available to OSI Systems Management.
