User contracts
If you are interested in the VTA functionality offered by TELDAS, you should sign one of the following user contracts, but first we recommend you to consult our FAQ "How to become a User":
- VTA Benutzervertrag (German) or VTA User Contract (English): This is the standard contract that enables you to download your VTA files from the INet-Server.
- In case you want to also use the INA functionalities of the INet-Server, you don't need to sign the VTA User contract but you can sign instead the INA Benutzervertrag (German) or INA User Contract (English), as VTA is already included in this contract.
