Network emulator for private communication terminal equipment

A communication arrangement with a private communication system to which private communication terminal equipment that cannot be directly connected are allocated, comprising:

• the private communication system and the allocated private communication terminal equipment each being rigidly connected to respective first and second terminal equipment emulation units;
• the first and second terminal equipment emulation units respectively rigidly allocated to the communication terminal equipment and to the communication system forming a terminal equipment emulation unit pair which are both rigidly connected to at least one public dialed communication network via at least one respective terminal;
• and
• means for automatic call set up via the public dialed communication network provided in the terminal equipment emulation unit pair,
• said means controlling the connection of at least one message path and of an additional signaling path for control of additional performance features of the private communication system via the public dialed communication network, and
• checking connection suitability of the at least one message path and the additional signaling path to the terminal equipment emulation unit pair.
