m he National Institute of Standards and Technology was established in 1988 by Congress to "assist
industry in the development of technology . . . needed to improve product quality, to modernize
manufacturing processes, to ensure product reliability and to facilitate rapid commercialization ... of
. . .
products based on new scientific discoveries."
NIST, originally founded as the National Bureau of Standards in 1901, works to strengthen U.S.
industry's competitiveness; advance science and engineering; and improve public health, safety, and the
environment. One of the agency's basic functions is to develop, maintain, and retain custody ofthe national
standards of measurement, and provide the means and methods for comparing standards used in science,
engineering, manufacturing, commerce, industry, and education with the standards adopted or recognized
by the Federal Government.
As an agency of the U.S. Commerce Department's Technology Administration, NIST conducts basic
and applied research in the physical sciences and engineering and performs related services. The Institute
does generic and precompetitive work on new and advanced technologies. NIST's research facilities are
located at Gaithersburg, MD 20899, and at Boulder, CO 80303. Major technical operating units and their
principal activities are listed below. For more information contact the Public Inquiries Desk, 301-975-3058.

Reports on Computer Systems Technology
The National Institute of Standards and Technology (NIST) has a unique responsibility for computer
systems technology within the Federal government. NIST's Computer Systems Laboratory (CSL) devel-
ops standards and guidelines, provides technical assistance, and conducts research for computers and
related telecommunications systems to achieve more effective utilization of Federal information technol-
ogy resources. CSL's responsibilities include development of technical, management, physical, and ad-
ministrative standards and guidelines for the cost-effective security and privacy of sensitive unclassified
information processed in Federal computers. CSL assists agencies in developing security plans and in
improving computer security awareness training. This Special Publication 823 series reports CSL re-
search and guidelines to Federal agencies as well as to organizations in industry, government, and
academia.

ISDN Conformance Testing
Layer 2 -- Data Link Layer (LAPD)
Part 1: Basic Rate Interface, User Side
ABSTRACT
This document defines the abstract test specifications to verify conformance ofequipment to theLayer 2, DataLink
Layer, Link Access Procedure on the D Channel (LAPD) of an Integrated Services Digital Network (ISDN) at the
user-side of the user-network interface, for the Basic Rate Interface (BRI) access arrangements, as defined in the
International Telegraph and Telephone Consultative Committee (CCITT) Recommendation Q.921 and American
National Standard ANS T1.602. The test scripts are written in the internationally standardized Tree and Tabular
Combined Notation, TTCN. These tests were developed, internationally harmonized, and approved by members of
the North American ISDN Users' Forum (NIU/91-0012).
