The TTCN standard (ISO 9646-3) has reached IS status, and has been
submitted for publication by ISO; extensions to cover concurrency are also
being progressed (not sure of the status of this)


ISO 8824/8825 - ASN.1 Syntax and Basic Encoding Rules - were published as
International Standards in 1990; extensions to the syntax are also being
worked on (8824/DAM1).

ISODE (the ISO Development Environment) contains various ASN.1 based
tools, and is freely available. I don't know of any specific TTCN
compilers currently available.


Here at NPL we have been working on a set of tools aimed at making the
production of TTCN test suites easier, using a new form of the notation
called "Developer's TTCN". This can then be turned into standard TTCN when
needed. I'll send you more details if interested.


Hope that helps.


Simon.
