The Seven Digit Call Connection Service

CCS stands for Call Connection Service. The system was developed a few years ago as an optimisation of the "G2 Call-sign Routing", which uses the Icom DSTAR systems for the targeted self built repeaters, hotspots and private modems in one open network.

The first 3 digits of the Identifier follows the Mobile Country Code (MCC) numbering as defined in the ITU-T Recommendation E.212.

This first digits of the MCC identify the geographical region or Continent:
  1. Test networks
  2. Europe
  3. North America and the Caribbean
  4. Asia and the Middle East
  5. Oceania
  6. Africa
  7. South and Central America
  8. Worldwide

The first 3 digits are the Mobile Country Codes (MCC), identify the Country. Some examples are:
After the Mobile Country Codes (MCC), amateur radio DMR networks append a 4-digit code for users and a 3-digit code for repeaters.

Further information about the ITU-MCC can be found here: Wikipedia and at the ITU
