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