ISO/IEC TR 10738 : 1993
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. IS0 and IEC techni-
cal 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, ISOBEC
JTC 1.
The main task of technical committees is to prepare International Standards, but in exceptional circum-
stances a technical committee may propose the publication of a Technical Report of one of the following
types:
- type 1, when the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts;
- type 2, when the subject is still under technical development or where for any other reason there is
the future but not immediate possibility of an agreement on an International Standard;
- type 3, when a technical committee has collected data of a different kind from that which is normally
published as an International Standard (“state of the art,” for example).
Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether
they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to
be reviewed until the data they provide are considered to be no longer valid or useful.
ISOBEC TR 10738, which is a Technical Report of type 3, was prepared by Joint Technical Committee ISO/
IEC JTC 1, Information technology.

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 technologies 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:
ISO/IEC 8802-3 [ANSVIEEE Std 802.3, 1992 Edition], a bus utilizing CSMNCD as the access

method,
ISO/IEC 8802-4 [ANSIDEEE Std 802.4-19901, a bus utilizing token passing as the access method,
b)
ISO/IEC 8802-5 [ANSVIEEE Std 802519921, a ring utilizing token passing as the access method,
c)
IS0 8802-7, a ring utilizing slotted ring as the access method.
d)
IS0 8802-2 [ANSVIEEE 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.

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 volun-
tarily and without compensation. They are not necessarily members of the Institute. The standards devel-
oped within IEEE represent a consensus of the broad expertise on the subject within 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 reaf-
firmed, 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 represent 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 pro-
vide 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:

IEEE Standards documents are adopted by the Institute of Electrical and Electronics Engineers without
regard to whether their adoption may involve patents on articles, materials, or processes. Such adop-
tions does not assume any liability to any patent owner, nor does it assume any obligation whatever to
parties adopting the standards documents.

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 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 these technologies are as follows:
IEEE Std 802l: 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.
IEEE Std 802.1D: MAC Bridging. Specifies an architecture and protocol for the
interconnection of IEEE 802 LANs below the MAC service

Conformance test methodology
An additional standards series, identified by the number 1802, has been established to identify the conform-
ance test methodology documents for the 802 family of standards. This makes the correspondence between
the various 802 standards and their applicable conformance test requirements readily apparent. Thus the
conformance test documents for 802.3 are numbered 1802.3, the conformance test documents for 802.5 will
be 1802.5, etc. Similarly, IS0 will use 18802 to number conformance test standards for 8802 standards.
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 errors, and to incorporate new related material. Information on the current revision status of this
standard may be obtained by contacting

Recommended practice for use of unshielded
twisted pair cable (UTP) for token ring data
transmission at 4 Mbit/s
1. Introduction to the recommended practice
This supplement to ISO/iEC 8802-5 : 1992 (ANSI/IEEE Std 802.5-1992) describes the recommended prac-
tice for using unshielded twisted pair cables (UTP) for transmitting data at 4 Mb/s. A standard to support
token ring over unshielded twisted pair is a subject for future study.
1.1 Scope
There are many applications where UTP can be successfully used if noise sources are controlled as recom-
mended in this document. The need to use existing wiring, or to minimize short-term installation costs,
makes the decision to use UTP for 4 Mb/s token ring operation an appropriate business decision for many
installations.
When UTP is used in the channel, the resulting token ring operation will be limited. The limitations include
a maximum attach capability of 72 stations instead of 250. In addition, the error rate performance is highly
dependent upon noise sources that may interfere with ring operation. Guidance is provided to help minimize
ring error rate.
The transmit and receive waveforms are different from those described in 7.5 of ISOLEC 8802-5 due to the
need for media filters to prevent excessive electromagnetic radiation from the UTP and to control common-
mode noise. The characteristics at the media filter are defined in clause 3. It is an element in the transmission
signal path and is matched to the token ring transmitter and receiver. Since a media filter may be designed
for a particular transmitter/receiver, it may not be suitable for use with other stations due to electromagnetic
radiation compliance. Therefore, interchangeability of stand-alone UTP media filters across attaching sta-
tions is not assured by this practice.

1.2 Overview
Within this document, UTP will be used to mean 100 SZ unshielded twisted pair cable. This type of cable has
previously been called telephone wire. Token ring operation using UTP media, while not conforming to
ISO/IEC 8802-5, will provide satisfactory operation in many applications when used according to these rec-
ommendations. In many applications, the use of UTP as the lobe media (the wire used f
