GL Communications Strengthens ED-137 Recorder Testing for IP-Based Air Traffic Management Systems
Summary
GL Communications announced enhanced capabilities in its MAPS ED-137 Recorder Emulator to validate, automate, and performance-test VoIP recorder interfaces for IP-based Air Traffic Management networks. The emulator now supports stress testing of hundreds of RTSP recording sessions, verifies Call Record Data including R2S and R2S-TLV metadata, and provides per-session audio recordings with CSV traceability. Recent enhancements add improved codec and user-agent handling, expanded IPv6 support, broader Python API automation, validation against VOTER systems, and configurable RTP over UDP parameters. The solution supports EUROCAE ED-137B and ED-137C Volume 4 Recorder standards and integrates with GL's wider ATM testing portfolio to help developers and integrators automate regression and interoperability testing prior to deployment.
