ASN.1 - Abstract Syntax Notation One
ASN.1 (ITU-T Recommendation X.680-683) is a generic notation standardized by ISO and ITU for the specification of data types and values. The general idea behind ASN.1 is to describe data type information independent of the transfer format.
The original use of ASN.1 has been the information description in high-level protocols like FTAM, CMIP, MHS, DS, VT, etc. Today it is also frequently used in numerous other telecommunication protocols and applications.
ASN.1 data types and values can be defined in modules that can be used in TTCN and in SDL. This makes it possible to use the data types of an application both in the SDL specification and in the TTCN test suite, which assures consistency between the information transferred in the system specification and the test specification.
