Trans European Services for Telematics between Administrations

The Trans European Services for Telematics between Administrations (TESTA) system was the private IP-based network of the European Union. TESTA was a telecommunications interconnection platform for secure information exchange between the European public administrations.

TESTA was not a single network, but a network of networks, composed of the EuroDomain backbone and Local Domain networks. The EuroDomain was a European backbone network for administrative data exchanges acting as a network communication platform between local administrations.

TESTA has been superseded by STESTA by end of April 2008.
