3 Definition of terms, symbols and abbreviations
3.1 Terms

For the purposes of the present document, the terms given in ETSI ES 201 873-1 [1],

Recommendation ITU-T X.660 [11] and the following apply:

associated TTCN-3 type: TTCN-3 type equivalent, obtained by transforming of the corresponding ASN.1 type

definition according to clause 9.1 of the present document

NOTE: Associated TTCN-3 types and values may not exist in a visible way; this term is used to identify the part

of the abstract information carried by the related ASN.1 type or value, which have significance from the

point of view of TTCN-3 (also called the TTCN-3 view).
metatype "OPEN TYPE": used to explain the ASN.1 to TTCN-3 conversion process
NOTE: It does not exist in the input ASN.1 module or the output TTCN-3 module.

root type: Definition in ETSI ES 201 873-1 [1] applies with the following addition: in case of types based on imported

ASN.1 types, the root type is determined from the associated TTCN-3 type (see clause 8).

3.2 Symbols

3.3 Abbreviations

For the purposes of the present document, the abbreviations given in ETSI ES 201 873-1 [1] and the following apply:

XER XML Encoding Rules of ASN.1
4 Introduction

When using ASN.1 with TTCN-3 all features of TTCN-3 and statements given in clause 4 of ETSI ES 201 873-1 [1] do

apply. In addition, when supporting the present document, TTCN-3 becomes fully harmonized with ASN.1 which may

be used with TTCN-3 modules as an alternative data type and value syntax. The present document defines the

capabilities required in addition of those specified in ETSI ES 201 873-1 [1] when ASN.1 is supported. The approach

used to combine ASN.1 and TTCN-3 could be applied to support the use of other type and value systems with TTCN-3.

However, the details of this are not defined in the present document.

ETSI ES 201 873-1 [1] specifies the core capabilities of the TTCN-3 language. Other language mappings (see [i.27],

[i.28] and [i.29]) and TTCN-3 language packages as ETSI ES 202 781 [i.20], ETSI ES 202 782 [i.21], ETSI

ES 202 784 [i.22], ETSI ES 202 785 [i.23], ETSI ES 202 786 [i.24], ETSI ES 202 789 [i.25], ETSI ES 203 022 [i.30],

ETSI ES 203 790 [i.31] may specify extensions to the core language that may define a

3 Definition of terms, symbols and abbreviations
3.1 Terms

For the purposes of the present document, the terms given in ETSI ES 201 873-1 [1],

Recommendation ITU-T X.660 [11] and the following apply:

associated TTCN-3 type: TTCN-3 type equivalent, obtained by transforming of the corresponding ASN.1 type

definition according to clause 9.1 of the present document

NOTE: Associated TTCN-3 types and values may not exist in a visible way; this term is used to identify the part

of the abstract information carried by the related ASN.1 type or value, which have significance from the

point of view of TTCN-3 (also called the TTCN-3 view).
metatype "OPEN TYPE": used to explain the ASN.1 to TTCN-3 conversion process
NOTE: It does not exist in the input ASN.1 module or the output TTCN-3 module.

root type: Definition in ETSI ES 201 873-1 [1] applies with the following addition: in case of types based on imported

ASN.1 types, the root type is determined from the associated TTCN-3 type (see clause 8).

4 Introduction

When using ASN.1 with TTCN-3 all features of TTCN-3 and statements given in clause 4 of ETSI ES 201 873-1 [1] do

apply. In addition, when supporting the present document, TTCN-3 becomes fully harmonized with ASN.1 which may

be used with TTCN-3 modules as an alternative data type and value syntax. The present document defines the

capabilities required in addition of those specified in ETSI ES 201 873-1 [1] when ASN.1 is supported. The approach

used to combine ASN.1 and TTCN-3 could be applied to support the use of other type and value systems with TTCN-3.

However, the details of this are not defined in the present document.

ETSI ES 201 873-1 [1] specifies the core capabilities of the TTCN-3 language. Other language mappings (see [i.27],

[i.28] and [i.29]) and TTCN-3 language packages as ETSI ES 202 781 [i.20], ETSI ES 202 782 [i.21], ETSI

ES 202 784 [i.22], ETSI ES 202 785 [i.23], ETSI ES 202 786 [i.24], ETSI ES 202 789 [i.25], ETSI ES 203 022 [i.30],

ETSI ES 203 790 [i.31] may specify extensions to the core language that may define additional rules for the ASN.1 to

TTCN-3 mapping. These additional rules are specified in the relevant other documents and need to be supported only if

the implementation claims to support the other document.

5 General
5.1 Approach

TTCN-3 provides a clean interface for using ASN.1 definitions (as specified in Recommendations ITU-T X.680 [2],

X.681 [3], X.682 [4] and X.683 [5]) in TTCN-3 modules.

In general, there are two approaches to the integration of other languages with TTCN-3, which will be referred to as

implicit and explicit mapping. The implicit mapping makes use of the import mechanism of TTCN-3, denoted by the

keywords language and import, in which case the TTCN-3 tool shall prod

1 Scope

The present document defines a normative way of using ASN.1 as defined in Recommendations ITU-T X.680 [2],

X.681 [3], X.682 [4] and X.683 [5] with TTCN-3. The harmonization of other languages with TTCN-3 is not covered

by the present document.

3 Definition of terms, symbols and abbreviations
3.1 Terms

For the purposes of the present document, the terms given in ETSI ES 201 873-1 [1],

Recommendation ITU-T X.660 [11] and the following apply:

associated TTCN-3 type: TTCN-3 type equivalent, obtained by transforming of the corresponding ASN.1 type

definition according to clause 9.1 of the present document

NOTE: Associated TTCN-3 types and values may not exist in a visible way; this term is used to identify the part

of the abstract information carried by the related ASN.1 type or value, which have significance from the

point of view of TTCN-3 (also called the TTCN-3 view).
metatype "OPEN TYPE": used to explain the ASN.1 to TTCN-3 conversion process
NOTE: It does not exist in the input ASN.1 module or the output TTCN-3 module.

root type: Definition in ETSI ES 201 873-1 [1] applies with the following addition: in case of types based on imported

ASN.1 types, the root type is determined from the associated TTCN-3 type (see clause 8).
