`
`Abstract: The ISO/IEC CSMA/CD Media Access Control (MAC) is given an additional set of parameters for
`100 Mbls operation. 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 Q 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.
`Keywords: 100BASE-FX, 100BASE-'l', 10OBASE-T4, 100BASE-TX, 10OBASE-X, Auto-Negotiation, Fast

`
`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 reaflirmation. When a document is more
`than five years old and has not been reaflirmed, 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 afliliation 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:

`
`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.)
`
`
`
`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:
`
`- IEEE Std 8021:
`
`- 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
`fonns 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
`enviromnent 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.
`
`1The 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.lA should be consid-
`ered as references to IEEE Std 802.
`
`This is ani./-\rchive IEEE Standard.
`
`It has been superseded by a later version of this standard.

`Layer technology:

`
`The following additional working groups have authorized standards projects under development:

`
`- IEEE 802.14:
`
`Wireless LAN Medium Access Control (MAC) Sublayer and
`Physical Layer Specifications
`
`Standard Protocol for Cable-TV Based Broadband
`Communication Network
`
`The reader of this standard is urged to become familiar with the complete family of standards.
`
`Conformance test methodology
`
`identified by the number 1802, has been established to identify the
`An additional standards series,
`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.

`
`IEEE Std 802.3u-1995
`
`At the time this standard (IEEE Std 802.3u-1995) was published, the IEEE 802.3 standard consisted of the
`following published documents:
`
`— ISO/IEC 8802-3: 1993 [ANSI/IEEE Std 802.3, 1993 Edition]
`— IEEE Std 802.3j-1993, Fiber Optic Active and Passive Star-Based Segments, Type 10BASE-F
`(Clauses 15-18)
`— IEEE Std 802.3k-1992, Layer Management for 10 Mb/s Baseband Repeaters (Clause 19)
`— IEEE Std 802.31-1992, Type 10BASE-T Protocol Implementation Conformance Statement (PICS)
`Proforma (Subclause 14.10)
`— IEEE Std 802.3p-1993 and IEEE Std 802.3q-1993, Guidelines for the Development of Managed
`Objects (GDMO) (ISO/IEC 10165-4) Format for Layer-Managed Objects (Clause 5) and Layer
`Management for 10 Mb/s Baseband Medium Attachment Units (MAUs) (Clause 20)
`— IEEE Std 1802.3d-1993, Type 10BASE-T Medium Attachment Unit (MAU) (Conformance Test
`Methodology (Clause 6)
`
`At the time this standard was published, there was revision and supplementary material that had been
`approved and scheduled for publication. 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

`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.
