Frequentis will provide Air Traffic Control Services Ltd. (ATCSL) with two voice communication systems (VCS) for Liverpool airport in the North of England; Frequentis' next generation, cloud- ready voice communication system, X10, to be installed as the contingency system; Systems Interface Limited contracted for design, installation, and integration. Frequentis will implement its VCS 3020X for the main system and its next generation VCS, the X10. Based on an agile service-oriented architecture, the X10 opens the door for the future of voice communications.

It is designed from its origin to be open for integration with other systems to enable new concepts such as the unified aeronautical communication solutions. Frequentis X10 VCS implements the multi-redundancy concept. This also includes the market-unique feature of parallel delivery of two audio streams for every air/ground connection to guarantee uninterrupted audio, even in case of single network outage.

This means that switch-over time no longer exists. X10 leads the way and adds value to every ATC operation. ATCSL are a wholly owned company within the Peel Airports Group, who owns Liverpool Airport.

The systems are currently being installed and configured with site and factory acceptance tests taking place in the latter half of 2023.
