Phased migration of existing VHF radio communications “ground-ground” and “air-ground” between VHF radio centers and VCS in ACC/FIC to the use of VoIP technology

The implementation of the project will replace the communication connectivity between the Voice Communication Systems (VCS) and ground VHF radio stations, currently provided by Time Division Multiplexing (TDM) telecommunications infrastructure, with IP-based connectivity relying on contemporary and prospective concepts and technologies. These activities arise from Task COM11 – Implementation of Voice over Internet Protocol (VoIP) in ATM from the document Local Single Sky Implementation Monitoring (LSSIP) of the Republic of Bulgaria.
