A repeater and added Physical Layers, known collectively as 100BASE-T, as well as sig- nificant additional supporting material for a Media Independent Interface (MII), management, and automatic configuration, are specified. This includes 100BASE-T4, which uses four pairs of Category 3, 4, or 5 generic twisted, balanced cable; 100BASE-TX, which uses two pairs of Category 5 balanced cable or 150 shielded balanced cable; and 100BASE-FX, which uses two multi-mode fibers. Fibre Distributed Data Interface (FDDI) media interface specifications are referenced to provide the 100BASE-TX and 100BASE-FX physical signal- ing channels, defined under the subcategory 100BASE-X.

IEEE Standards documents are developed within the Technical Committees of the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the com- mittees serve voluntarily and without compensation. They are not necessarily members of the Insti- tute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an inter- est in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is sub- jected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep- resent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O. Box 1331 Piscataway, NJ 08855-1331 USA Note: Attention is called to the possibility that implementation of this standard may require use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. The IEEE shall not be responsible for identifying all patents for which a license may be required by an IEEE standard or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention. Authorization to photocopy portions of any individual standard for internal or personal use is granted by the Institute of Electrical and Electronics Engineers, Inc., provided that the appropriate fee is paid to Copyright Clearance Center.

Introduction (This introduction is not part of IEEE Std 802.3u-1995.) This standard is part of a family of standards for local and metropolitan area networks. The relationship between the standard and other members of the family is shown below. (The numbers in the figure refer to IEEE standard numbers.) I Y T R U C E S 0 1 2 0 8 .

This family of standards deals with the Physical and Data Link layers as defined by the International Organi- zation for Standardization (ISO) Open Systems Interconnection Basic Reference Model (ISO 7498 : 1984). The access standards define several types of medium access technologies and associated physical media, each appropriate for particular applications or system objectives. Other types are under investigation. The standards defining the technologies noted above are as follows: 1 • IEEE Std 802 : • ANSI/IEEE Std 802.1B [ISO/IEC 15802-2]: • ANSI/IEEE Std 802.1D [ISO/IEC 10038]: • ANSI/IEEE Std 802.1E [ISO/IEC 15802-4]: Overview and Architecture. This standard provides an over- view to the family of IEEE 802 Standards. This document forms part of the 802.1 scope of work. LAN/MAN Management. Defines an Open Systems Interconnection (OSI) management-compatible architecture, and services and protocol elements for use in a LAN/MAN environment for performing remote management. MAC Bridging. Specifies an architecture and protocol for the interconnection of IEEE 802 LANs below the MAC service boundary. System Load Protocol. Specifies a set of services and protocol for those aspects of management concerned with the loading of systems on IEEE 802 LANs. 1 The 802 Architecture and Overview standard, originally known as IEEE Std 802.1A, has been renumbered as IEEE Std 802. This has been done to accommodate recognition of the base standard in a family of standards. References to IEEE Std 802.1A should be consid- ered as references to IEEE Std 802. iv Authorized licensed use limited to: Tsinghua University Library.

Conformance test methodology An additional standards series, identified by the number 1802, has been established to identify the conformance test methodology documents for the 802 family of standards. Thus the conformance test documents for 802.3 are numbered 1802.3, the conformance test documents for 802.5 will be 1802.5, and so on. Similarly, ISO will use 18802 to number conformance test standards for 8802 standards. Authorized licensed use limited to: Tsinghua University Library.

Also, a new edition of ISO/IEC 8802-3 was in preparation to con- solidate a significant amount of the above material. Information on the current state of this and other IEEE 802 standards may be obtained from Secretary, IEEE Standards Board 445 Hoes Lane P.O.

Thrush Patent information The IEEE Standards Board calls attention to the fact that it is claimed that portions of IEEE Std 802.3u-1995 are the subject of patents owned by a number of companies. The IEEE takes no position with respect to patent validity. Each of these companies has assured IEEE that it is willing to grant a license on these patents on reasonable and nondiscriminatory terms to anyone wishing to obtain such a license. The undertakings of these companies in this respect are on file with the IEEE Standards Department, and the license details may be obtained by contacting the Standards Department. vi Authorized licensed use limited to: Tsinghua University Library.
