Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS was generated using a template provided by TCR-TR 046. The procedures defined there were
used to add elements to the library, ensuring that its rules apply to the contents of this ETS.
NOTE: TCR-TR 046 is only available to ETSI members.
An electronic version of the ETSI ASN.1 library is available to all subscribers to the ETSI Documentation
Service or can also be obtained from the ETSI PEX helpdesk:

1 Scope
This European Telecommunication Standard (ETS) defines the ETSI ASN.1 library. The library has been
set up for two reasons:
- capture common application element definitions within ETSI in order to reduce the overall protocol
maintenance effort;
- enlarge the reusability of ETSI protocols.
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] CCITT Recommendation X.208 (1988): "Specification of abstract syntax
notation one (ASN.1)" (technically aligned with ISO 8824).
[2] ITU-T Recommendation X.680 (1994): "Information technology - Open System
Interconnection - Abstract Syntax Notation One (ASN.1): Specification of Basic
Notation" (also published as ISO 8824-1).
[3] ETS 300 351 (1994): "ETSI object identifier tree; Rules and registration
procedures".
3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
ASN.1 definition: A definition resulting from one of the alternatives for an ASN.1 "Assignment" as defined
by ITU-T Recommendation X.680 [2].
Common Application Element (CAE): An ASN.1 type definition or ASN.1 value definition that can or is
commonly used in other ASN.1 modules.
ETSI-LIB: The most recent ETS containing the current version of the ASN.1 library, hence this ETS.
LIB-INDEX: The most recent ETR containing the current version of index to the ASN.1 library, hence
ETR 210.
Library Maintenance Organization (LMO): An organization maintaining the ASN.1 library and the ASN.1
library Index.
library module: An ASN.1 module containing one or several Common Application Element definitions.
library procedures: A set of procedures that modify the ASN.1 library as well as the ASN.1 library Index
in terms of contents and structure.
library rules: A set of rules applicable to the ASN.1 library that preserves the soundness and structure of
the library.
validated ASN.1: ASN.1 definitions are valid if they conform with the guidelines defined in ETR 060. For
the purpose of this ETS these guidelines are to be considered as binding. Validation is done by the LMO.

3.2 Abbreviations
For the purposes of this ETS, the following definitions apply:
ASN.1 Abstract Syntax Notation One
4 ETSI library definition
The module "ETSI-Library" is the main module of the library. Every reference from other standards to
definitions contained herein shall be made using the ASN.1 import mechanism and the corresponding
object identifier value of this main module. No other module of this standard shall be referenced.
NOTE 1: ETS 300 351 [3] describes the structure of the ETSI object identifier tree. The ASN.1
library of ETSI is given a dedicated branch unlike other ETSs which have their ETS
number incorporated in the object identifier value. However, the current revision of
ETS 300 351 [3] does not reflect the existence of the library.
The ASN.1 definitions contained in this ETS can be automatically extracted from its electronic form. The
resulting ASN.1 modules should be used in order to verify any other standard or recommendation with
references to this ETS.
An index of users of this standard is found in LIB-INDEX, which lists for every definition contained in this
ETS the corresponding standards and recommendations that import this definition. Additionally it lists
standards and recommendations that do not import these definitions but rather re-define them
themselves.
NOTE 2: In order to achieve its intended use, the index needs to be re-issued whenever a new
version of this ETS is created. Furthermore, it has to be re-issued to reflect a changed
outside world (e.g. new users).
4.1 ASN.1 module definitions of the library version 1.1
This version of the library is the interface to the standards and recommendations listed in LIB-INDEX, no
changes shall be applied to any of the definitions contained herein without agreement of all the users (and
possibly re-definers) of this definition.
NOTE: ASN.1 definitions ending with e.g. "-v2-3" are kept for compatibility purposes from an
earlier version of this library, in the above example from version 2.3. Any definition
without such a suffix is the most recent one, standards using older versions of the
library have the choice to register for both, the original and the most recent one.
4.1.1 Interface module
The ASN.1 source lines are preceded by line-numbers at the left margin in order to enable the usage of
the cross-reference in annex B.

For every (Value)Assignment in the root ASN.1 module all the used defined types and defined values,
which are defined within the ASN.1 module or imported from ASN.1 modules, are replaced by the
constructs this type or value is composed of.
The fully expanded ASN.1 root module is itself a correct and equivalent representation of the ETSI library.
It allows an overview of all nested definitions.
