It is an essential component in constructing ATN-compliant communication networks, interconnecting air and ground infrastructures. The Router embodies much of the functionality of ATN and is the element which ensures the world-wide, open, transparent connectivity characteristic of ATN.

The Airtel ATN Router supports the exchange of routing information for ground and air-ground systems. The ATN Router is described in the ATN Manual, issued by ICAO.

The Airtel ATN Router is compliant with the ICAO CNS/ATM Package-1 Internet SARPs.

Airtel also provides ATN routers for the Aeronautical Message Handling System (AMHS). AMHS is the standard for aeronautical ground-ground communication that replaces the existing Aeronautical Fixed Telecommunications Network (AFTN).
