Air traffic control centers are required to provide continuous "ground/ground" and "ground/air" voice communication recordings with synchronized flight related data, for establishing “air traffic incident” chronology, replay, improving safety, audits, statistics, and training purposes.

ED137/4B defines inter-operability standards for the next generation VoIP Air Traffic Recorder. These next generation recorders are specially designed for all traffic control towers and centers to simplify the recording, archiving, and playback of voice communications.

GL’s MAPS™ ED137 Recorder (PKS117) can simulate Recorder interface for both Air-to-Ground (AG) and Ground-to-Ground (GG) calls at Controller Working Position (CWP), Ground Radio Station (GRS) and Recorder endpoints as per ED-137/4B, as defined under EUROCAE (European Organization for Civil Aviation Equipment) Working Group 67.

MAPS™ ED137 Recorder can simulate AG/GG call recording towards Recorder and testing Recorder interface of CWP/VCS and GRS.

MAPS™ ED137 Recorder supports Real Time Streaming Protocol (RTSP) to establish, terminate and maintain media sessions to deliver media to recording servers. Active recording requires an established session (i.e. a certain number of parameters that are exchanged between entities prior to any recording). CWP/VCS, Radio and Recorder use RTSP for such sessions. As RTSP relies on a transport layer protocol (TCP or UDP), these entities use SIP to exchange capabilities and connection information (i.e. IP address, port number, and transport protocol).

The MAPS™ profile editor feature allows users to easily configure multiple CWPs, GRS and Recorder profiles, allowing to simulate multiple CWP, GRS and Recorder entities. The product also supports transmission and detection of various RTP audio traffic such as real-time audio, voice file, digits, single tone and dual tones. The software not only provides complete control over call scenarios to be tested, but also the ability to customize the network parameters for signaling and VoIP traffic. It has the capability of generating more than hundreds of recording sessions to verify performance and load testing.

GL tools for signalling emulation and voice quality testing offer an end-to-end test solution for testing connections from the radio interfaces to the Controller Working Position (CWP) and recording voice communications over the network. GL’s Air Traffic Management Solution also includes MAPS™ ED-137 Telephone Emulators and MAPS™ ED-137 Radio Emulators.
