              Solution Description 
        This solution is used within the European Union.  It combines standards associated with (None-Data) with those for C-C: DATEX Messaging TCP. The (None-Data) standards include an unspecified set of standards at the upper layers.  The C-C: DATEX Messaging TCP standards include lower-layer standards that support partially secure communications between two centres as commonly used in Europe.
