Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO 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. ISO and IEC technical 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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 bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
In exceptional circumstances, 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), it may decide by a simple majority
vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature
and does not have to be reviewed until the data it provides are considered to be no longer valid or useful.
Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC TR 10171 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
This second edition cancels and replaces the first edition (ISO/IEC TR 10171:1994), which has been technically
revised.

Introduction
The HDLC classes of procedures have been utilized in a number of International Standards and ITU-T Recommendations as
the basis for specific data link layer protocol specifications. This Technical Report provides an indication of the class of
procedures and optional functions used in the realization of each designated data link layer protocol. The protocols covered
include:
� ISO/IEC 7776
� ISO/IEC 8802-2 LLC type 1
� ISO/IEC 8802-2 LLC type 2
� ITU-T Recommendation G.764
� ITU-T Recommendation Q.921 (I.441) LAPD
� ITU-T Recommendation Q.922 LAPF
� ITU-T Recommendation T.90
� ITU-T Recommendation V.42
� ITU-T Recommendation V.76
� ITU-T Recommendation V.120
� ITU-T Recommendation X.25 LAPB
� ITU-T Recommendations X.25/X.32
� ITU-T Recommendation X.75 SLP
� Internet Society Request for Comments: 1662
� IEEE TR 1550
Table 1 in this Technical Report lists these protocols, indicates the basic class of procedures used, and identifies the standard
optional functions used to realize the specific data link layer protocol. The footnotes following table 1 provide additional
explanation concerning the application of the optional function identified. As additional standard usages of the HDLC classes
of procedures are identified, this Technical Report will be updated. This Technical Report serves as the repository of record of
applications of the HDLC concepts, principles and classes of procedures in the realization of standard data link layer protocols.
Table 2 in this Technical Report serves as the repository of record for the standard XID format identifiers defined in
ISO/IEC 13239.
Table 3 in this Technical Report serves as the repository of record for standard mode-setting information field format
identifiers.
Table 4 in this Technical Report serves as the repository of record for the list of standard user-defined parameter set
identification values defined in ISO/IEC 13239.

TECHNICAL REPORT ISO/IEC TR 10171:2000(E)
Information technology — Telecommunications and information exchange
between systems — List of standard data link layer protocols that utilize
high-level data link control (HDLC) classes of procedures, list of standard
XID format identifiers, list of standard mode-setting information field
format identifiers, and list of standard user-defined parameter set
identification values
1Scope
This Technical Report lists the standard data link layer protocols that utilize HDLC based classes of procedures as defined in
ISO/IEC 13239 in their realization. The list indicates the basic repertoire (i.e. class of procedures) used plus the optional
functions employed.
This Technical Report lists the standard XID information field format identifiers. The list identifies the source document as
well as describing the characteristics of the information provided.
This Technical Report lists the standard mode-setting frame information field format identifiers. The list identifies the source
document as well as describing the characteristics of the information provided.
This Technical Report lists the standard user-defined parameter set identification values, as well as indicating the source and
use of the private parameter set.
NOTE - With the exception of ISO/IEC 7776 and ITU-T X.25 LAPB, which are designed to be complementary, the protocols listed do not
interwork. (There are differences in the usage of certain functions by different protocols.)
