Real-world validation of an ATC Data Link requires the costly coordination of airborne aircraft interacting with control towers. RTCD captures live ATN traffic from the ANSP IP network infrastructure, PDEC decodes this traffic and produces reports. It presents captured packet data on the IP ATN operational network in a human readable format that can be post-processed and enables visibility on the ATN network RTCD will work with any ATN Infrastructure. The Real Time Capture and Decoder (RTCD) is a standalone product developed by Airtel ATN in order for PDEC to analyse and log traffic. The following diagram presents the ATN functional model and shows where the Protocol Decoder sits

PDEC is a protocol decoder which decodes logs into information that can be used for data processing. Click here for more information about the characteristics of the Ground/Ground Router.
#Air navigation services provider software
The Airtel ANSP ATN Router is based on a common software technology base shared with the Airtel ATN Ground/Ground Router and it is customised for the ANSP domain. The ANSP ATN Router is an essential component in constructing an ATN-compliant ATS centre as it provides connectivity to the ATN network by providing a connection to a CSP. The Data Link service functions supported by AGDLS are: The Air Ground Data Link Server interfaces with ATN and FANS CSP networks to support ATN and FANS 1/A+ aircraft. The AGDLS product provides well-defined interfaces to ensure easy integration with different ATM systems. AGDLS provides, abstracting their underlying detail and enabling network operators to concentrate on the application services they deliver.


The AGDLS supports the Context Management (CM) and Controller Pilot Data Link Communications (CPDLC) protocols and interfaces with both ATN and FANS networks. The Airtel ATN Air/Ground Data Link Server (AGDLS) provides ATC communications for air traffic control centres with a Data Link communications backbone. Air Navigation Service Providers and users depend on a robust, scalable messaging service that can support both platforms. These networks have evolved as the Aeronautical Telecommunication Network (ATN) and the Future Air Navigation System (FANS). This Data Link network requires high-reliability and availability. Data Link networks are becoming an increasingly important communication method between ground control and aircraft.
