Abstract: This Local and Metropolitan Area Network standard, ISO/IEC 8802-3 : 1992
[ANSVIEEE Std 802.3, 19921, specifies the media access control characteristics for the
Carrier Sense Multiple Access with Collision Detection (CSWCD) access method. It also
specifies the media, Medium Attachment Unit (MAU) and physical layer repeater unit for
10 Mbls baseband and broadband systems and provides a 1 Mbls baseband implementa-
tion. Specifications for MAU types 10BASE5,1OBASE2, FOIRL (fiber optic inter-repeater
link), 1 OBROAD36, and 1BASE5 are included. Layer and sublayer interface specifications
are aligned to the IS0 Open Systems Interconnection Basic Reference Model and 8802
models. The 8802-3 internal model is defined and used.
Keywords: data processing, information interchange, local area networks, mode of data
transmission, network interconnection, models.

rganization for Standardization) and IEC (the
International Electrotechnical Commission) form the specialized system for
worldwide standardization. National bodies that are members of IS0 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. IS0 and IEC technical committees collaborate in fields of
mutual interest. Other international organizations, governmental and non-
governmental, in liaison with IS0 and IEC, also take part in the work.
In the field of information technology, IS0 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.
In 1985, IEEE Standard 802.3-1985 was adopted by IS0 Technical Committee 97,
infomzation processing system, as drafî International Standard ISODIS 8802-3.
Following the procedures described above, the Standard was subsequently approved by
IS0 and published as IS0 8802-3 : 1989, incorporating IS0 8802-3DAD 1 which had
resulted from the adoption by IS0 in 1987 of ANSI/IEEE Std 802.3a.
A further revision was subsequently approved by ISO/IEC JTC 1 in 1990,
incorporating ISO/IEC 8802-3/Amendments 2 and 5.
This third edition cancels and replaces ISO/IEC 8802-3 : 1990 and incorporates
Amendment 3 : Broadband medium attachment unit and broadband medium
specifications, Type lOBROAD36, which was approved in 1990, and Amendment 4:
Physical signaling, medium attachment, and baseband medium specifications,
Type 1 BASES, approved in 199 1.

This family of standards deals with the physical and data link layers as
defined by the IS0 Open Systems Interconnection .Basic Reference Model (IS0
7498 : 1984). The access standards define four types of medium access tech-
nologies and associated physical media, each appropriate for particular appli-
cations or system objectives. Other types are under investigation.
The standards defining these technologies are as follows:
(1) ISO/IEC 8802-3 [ANSYIEEE Std 802.3, 1992 Edition], a bus utilizing
CSMNCD as the access method,
(2) ISOAEC 8802-4 [ANSVIEEE Std 802.4-19901, a bus utilizing token pass-
ing as the access method,
(3) ISOAEC 8802-5 [IEEE Std 802.5-1992],* a ring utilizing token passing as
the access method,
(4) IS0 8802-7, a ring utilizing slotted ring as the access method.
IS0 8802-2 [ANSYIEEE Std 802.2-19891, Logical Link Control protocol, is
used in conjunction with the medium access standards.
The reader of this document is urged to become familiar with the complete
family of standards.
The main body of this standard serves for both the ISOAEC 8802-3 : 1992 and
ANSYIEEE Std 802.3,1992 Edition standards. IS0 and IEEE each have unique
foreword sections. The Annex applies to the IEEE standard only. The Ap-
pendixes serve as useful reference material to both standards.

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 committees serve voluntarily and without
compensation. They are not necessarily members of the Institute. The stan-
dards d d within IEEE represent a consensus of the broad expertise on the
subject the Institute as well as those activities outside of IEEE which have
expressed an interest 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 subjected to review at least once 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
e that they have the latest edition of any IEEE Standard.

changes in docume uld be in the form of a proposed change of text, to-

This family of standards deals with the physical and data link layers as de-
fined by the IS0 Open Systems Interconnection Basic Reference Mode1 (IS0
7498 :1984). The access standards define several types of medium access tech-
nologies and associated physical media, each appropriate for particular
applications or system objectives. Other types are under investigation.
The standards defining these technologies are as follows:
IEEE Std 802t : Overview and Architecture. This
standard provides an overview to the
family of IEEE 802 Standards, This
document forms part of the 802.1
scope of work.
IEEE Std 802.1D: MAC Bridging. Specifies an archi-
tecture and protocol for the intercon-
nection of IEEE 802 LANs below the
MAC service boundary.
t The 802 Architecture and Overview Specification, 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 considered as refer-
to IEEE Std 802.

Conformance Test Methodology
A new standards series, identified by the number 1802, has been established
to identify the conformance test methodology documents for the 802 family of
standards. This makes the correspondence between the various 802 standards
O
and their applicable conformance test requirements readily apparent. Thus
the conformance test documents for 802.3 are numbered 1802.3, the confor-
mance test documents for 802.5 will be 1802.5, and so on. Similarly, IS0 will
use 11802 to number conformance test standards for 8802 standards.

This edition of the standard defines 10 Mb/s baseband and broadband im-
plementations and a 1 MWs baseband implementation of the Physical Layer
using the CSMNCD access method. It is anticipated that future editions of the
standard may provide additional implementations of the physical layer to
support different needs (for example, media, and data rates).
This standard contains state-of-the-art material. The area covered by this
standard is undergoing evolution. Revisions are anticipated to this standard
within the next few years to clarify existing material, to correct possible er-
rors, and to incorporate new related material.

The IEEE 802.3 Working Group acknowledges and appreciates that many
concepts embodied in this standard are based largely upon the CSMNCD ac-
cess method earlier described in The Ethernet specification as written jointly
by individuals from Xerox Corporation, Digital Equipment Corporation, and
Intel Corporation. Appreciation is also expressed to Robert M. Metcalfe and
David R. Boggs for their pioneering work in establishing the original con-
cepts.
