Eventide is a member of the EUROCONTROL VOTE (VoIP in ATM Implementation and Transition Expert) group, which deals with validation and deployment matters related to next generation VoIP communications used in Air Traffic Management (ATM). Eventide is also a participant in EUROCAE Working Group 67 (WG-67).
Eventide at the 2019 FAA ED-137C Interoperability Event
Eventide’s NexLog VRS engineering team actively participated at the FAA’s Voice over Internet Protocol (VoIP) Interoperability Event, which took place in Atlantic City, New Jersey, from April 29th through May 10th, 2019. This FAA event created a multi-vendor proving ground to evaluate and validate the ED-137C specification as the international VoIP standard for ATM applications.
Replay Synchronization with Thales TopSky
Eventide’s NexLog DX-Series Voice Recording Systems (VRS) are capable of interoperation with the Thales TopSky Air Navigation System, providing synchronized replay of recorded audio along with replay of the controller’s working position screen imagery. Eventide’s Voice Recording System (VRS) has successfully passed testing at Thales Air Systems in Rungis, France for interoperability with TopSky ATC X release 3.20. Testing occurred during the week of 31 March, 2016. Tests including VRS ICD Protocol, replay search, play, pause, and resume were performed. The Eventide Recording System (VRS) passed all interoperability tests, and was able to record and playback voice synchronized with TopSky Playback server at the Controller Working Position (CWP).
Replay Synchronization via API
Eventide offers custom API options for the control of time-synchronized audio replay by third-party radar/air navigation applications.
