CCITT Recommendations
CCITT recommendations restrict international message transfer to ADMD-to-ADMD
routing. For example, if you want to send a message from PRMD-1 in country A to
PRMD-2 in country B, the message must follow the path shown in Figure 3-2.
MOTIS (ISO/IEC) Recommendations
MOTIS (ISO/IEC) recommendations allow private domains to communicate directly
with each other, whether in the same country or different countries. To send a
message from PRMD-1 in country A to PRMD-2 in country B, you could use a direct
path as shown in Figure 3-3.
