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

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

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).

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

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.

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] 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

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