Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized System for worldwide standardiza-
tion. 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 Felds of technical activity. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international organizations,
govemmental 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.
The main task of technical committees is to prepare International Standards. In excep-
tional circumstances 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 tan 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provide are considered to be no longer valid or useful.
ISOAEC TR 10171, which is a Technical Report of type 3, was prepared by Joint
Technical Committee ISO/IEC JTC 1, Znformution technology, Subcommittee SC 6,
Telecommunications and information exchunge between systems.

Introduction
The HDLC classes of procedures have been utilized in a number of International Standards and ITU-T (formally
CCITT) Recommendations as the basis for specific data link layer protocol specifications. This Technical Report
provides an indication of the class of procedures and optional fknctions used in the realization of each designated data
link layer protocol. The protocols covered include:
l ISO/IEC 7776
l ISO/IEC 8802-2 LLC type 1 and type 2
l ITU-T Recommendation G.764
l ITU-T Recommendation 4.921 (I.441) LAPD
l ITU-T Recommendation T.90
l ITU-T Recommendation V.42
l ITU-T Recommendation V. 120
l ITU-T Recommendations X.2YX.32
a ITU-T Recommendation X.25 LAPB
l ITU-T Recommendation X.75 SLP
Table 1 in clause 4 of 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 conceming the application of the optional fiwtion identified.
As additional Standard usages of the HDLC classes of procedures are identified, this Technical Report will be updated.
The Technical Report will serve 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.
This Technical Report also serves as the repository of record for the XID formst identifiers and private Parameter set
identifiers defined in ISO/IEC 8885, as amended.
