       Solutions 
                Solution Description 
        This solution is used within the U.S..  It combines standards associated with US: TMDD with those for C-C: NTCIP Messaging. The US: TMDD standards include upper-layer standards required to implement centre-to-centre communications with traffic management systems.  The C-C: NTCIP Messaging standards include lower-layer standards that support partially secure communications between two centres as commonly used in the US.
