IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Com-
mission) 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 estab-
lished by the respective organization to deal with particular fields of technical activity. ISO and IEC techni-
cal 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.
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 bsd-
ies for voting. Publication as an International Standard requires approval by at least 75% of the national bod-
ies casting a vote.
In 1995, ANSI/IEEE Std $02.9-1994 was adopted by ISCVIEC JTC 1, as draft International Standard ISO/
IEC DIS 8802-9. A further revision was subsequently approved by ISCYIEC JTC 1 in the form of this new
edition, which is published as International Standard ISO/IEC 8802-9: 1996.
For the purpose of assigning organizationally unique identifiers, the Institute of Electrical and Electronics
Engineers, Inc., USA, has been designated by the ISO Council as the Registration Authority. Communica-

This family of International Standards deals with the Physical and Data Link layers as defined by the ISO/
IEC Open Systems Interconnection Basic Reference Model (ISO/IEC 7498-l : 1994). The access standards
define several types of medium access technologies and associated physical media, each appropriate for par-
ticular applications or system objectives. Other types are under investigation.
The International Standards defining the access technologies are as follows:
ISO/IEC 8802-3 [ANSI/IEEE Std 802.31, a bus utilizing CSMAKD as the access method.
a>
b) ISO/IEC 8802-4 [ANSI/IEEE Std 802.41, a bus utilizing token passing as the access method.
ISO/IEC 8802-5 [ANSI/IEEE Std 802.51, a ring utilizing token passing as the access method.
C>
d) ISO/IEC 8802-6 [ANSI/IEEE Std 802.61, a dual bus utilizing distributed queuing as the access
method.
IS0 8802-7, a ring utilizing slotted ring as the access method.
e>
f) ISO/IEC 8802-9 [ANSI/IEEE Std 802.91, a unified access method offering global integrated services
to the desktop by accessing a variety of networks.
ISO/IEC TR 8802-l provides an overview of the LAN/MAN standards, along with details of their document
numbering.
ISO/IEC 8802-2 [ANSI/IEEE Std 802.21, Logical Link ControZ, is used in conjunction with the medium
access standards to provide the data link layer service to network layer protocols.
ISOLIEC 10038 [ANSI/IEEE Std 802.lD], Media Access Control (MAC) bridges, specifies an architecture
and protocol for the interconnection of IEEE 802 LANs below the level of the logical link control protocol.
ISO/IEC 15802-2 [ANSI/IEEE Std 802.lB], 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.
ISO/IEC 15802-4 [ANSI/IEEE Std 802. lE], System Load ProtocoZ, specifies a set of services and protocol
for those aspects of management concerned with the loading of systems in ISO/IEC LAN/MAN environ-
ments.
The main body of the International Standard serves for both the ISO/IEC 8802-9: 1996 and ANSI/IEEE Std
802.9, 1996 Edition standards. IS0 and IEEE each have a unique foreword.

ANSI/IEEE Std 802.9,1996 Edition
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordi-
nating Committees of the IEEE Standards Board. Members of the committees serve voluntarily and
without compensation. They are not necessarily members of the Institute. 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 interest in participating in the develop-
ment 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
societies and Standards Coordinating Committees are not able to provide an instant response to
interpretation requests except in those cases where the matter has previously received formal con-
sideration.
Comments on standards and requests for interpretations should be addressed to:

onfoamance 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, IS0 will use 18802 to number conformance test standards for 8802 standards.
lUUSIBIlXE Std 802.9, 1 Edition
The ongoing work of the IEEE 802 committee has resulted in standards for data communications in a local
area network (LAN) environment. As office workstations have proliferated, however, the demand for LANs
has substantially increased. This has led to the inevitable diversification in market requirements.
Since the typical office worker requires access to both data and voice services, among others, at the desktop,
there has been a growing trend toward integrated services (IS), namely voice, data, and video. Due to the
increasing need for facsimile, image transfer, and video services, these services are included in the general
category of the integration of voice and data services. Such integration offers potential economies to the
business customer in terms of reduced components (one port per station instead of two or more), and in
simpler management and maintenance (one network instead of two or more).
The provision of voice service is generally effected using unshielded twisted-pair wire. Not only is
this
medium widespread in typical office environments, but it is also inexpensive and easy to install
and
Vi

---------------------- Page: 8 ----------------------
c
maintain. In the vast majority of installations, there is spare capacity, and in these cases, the use of such a
medium is essentially free since the need for rewiring is significantly reduced. Moreover, with existing
technology, it is possible to provide medium- to high-performance data service over the unshielded twisted-
pair wire. This places special emphasis on the use of the unshielded twisted-pair wire to provide IS services.
This standard extends the scope and capability of existing twisted-pair wiring and thus reduces the incentive
for overlay wiring systems.
W ith respect to the provision of integrated services, there has been ongoing work in other standards bodies,
notably, the International Telecommunication Union-Telecommunication S tandardization Sector (ITU-T)
on the provision of such services through integrated services digital networks (ISDNs). While the principal
focus has been the provision of such services using public networks, efforts are under way [notably, in the
European Compu ter Manu facturers Association (ECMA)] to extend such services to customer premises
networks.
This standard defines a unified access me thod that offers global integrated services to the desktop by access-
ing a variety of publicly and privately administered backbone networks (e.g., ANS I FDDI, IEEE 802.x ’, and
ISDN). This standard will enable integrated services termial adapters (ISTEs) to be attached to IEEE 802.9
LANs and will allow them to communicate with other IS stations as well as data-only stations, voice-only
stations, and premises-based networks offering ISDN services. In addition, it specifies the use of unshielded
telephone twisted pair as the primary medium of distribution.
The use of terminal adaptor (TA) devices will permit the direct coupling of native mode terminal devices
such as data-only modules, voice modules, and ISDN basic rate terminals to the IEEE 802.9 interface. This
standard has been designed to accommodate the adaptation of ISDN basic rate station devices and IEEE
802.x station devices to the IEEE 802.9 interface. In summary, this standard represents the integration of
IEEE 802 services and ISDN services.
This standard contains state-of-the-art ma terial. The area covered by this standard is undergoing evolution.
Revisions are anticipated to this standard within the next few years to clarify existing ma terial, to correct
possible errors, and to incorporate new related ma terial. Information on the current revision state of this and
other IEEE 802 standards may be obtained from
