ANSI/IEEE Std 802.5r-1997 and 802.5j-1997, 1998 Edition
IEEE Standards
documents are developed within the IEEE Societies and the Standards Coordinating Com-
mittees of the IEEE Standards Association (IEEE-SA) 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 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 every five years for
revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is rea-
sonable 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 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 consideration.
Comments on standards and requests for interpretations should be addressed to:

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

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.
