Foreword
ISO (the International Organization for Standardization) and IEC (the lnter-
national 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 PO 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.
In the field of information technology, ISO and IEC have established a joint
technical committee, lSO/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.
Amendment 1 to International Standard lSO/IEC 10742:1994 was prepared
by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange
between Systems.

Introduction
This amendment to ISO/IEC 107421994 adds specifications answering to
requirements for DCE aspects and some new attributes for LAPBDLE
MOs and IVMOs.
These new specifications came out of the comments to DIS 10742. They
will be merged into the base document ISO/IEC 10742:1994 at the next
revision.
