Graphical and Textual Notations
The TTCN language supports two notations that are equivalent. The graphical notation (TTCN–GR) and a textual notation (TTCN–MP).

Application Areas
Currently, TTCN is mainly known within the telecommunications industry. However, it has broader areas of application, which can be summarized as follows:
