VoIP ATM Radio Simulator
MAPS™ ED-137 Radio simulator software simulates bulk Air-to-Ground calls per EUROCAE standards (ED-137C, ED137B) to perform functionality testing of network elements within VoIP ATM core network. The simulator software provides ability to customize the network parameters for simulating different call scenarios between Controller Working Positions (CWPs), Ground Radio Station (GRS) or Radio Media Gateways (RMG). Multiple CWPs/Radios are simulated to create multicast sessions and exchanged RTP packets are guided to monitoring tools for further analysis and troubleshooting.

VoIP ATM Controller Simulator
MAPS™ ED-137 Telephone simulator software simulates bulk VoIP Ground -to-Ground calls per EUROCAE standards (ED-137/2B). The simulator software provides ability to customize the network parameters for testing different call scenarios between Controller Working Positions (CWPs) across VoIP ATM network. Supported call types include- Instantaneous Access (IA), Priority Direct/Indirect Access (DA/IDA), Routine Tactical Direct/Indirect Access, Routine Strategic Direct/Indirect Access, Routine General Purpose Direct/Indirect Access, Position Monitoring Call (Combined A/G and G/G, A/G only, and G/G only). Supported events -send re-invite, send traffic, receive traffic, put active call on hold, transfer call, impair traffic, and play back the call on speaker For more information on the capabilities of the VoIP ATM Controller Simulator, click here and visit the webpage, download the product brochure, or email us info@gl.com.
VoIP ATM Recorder Simulator
GL’s MAPS™ ED137 Recorder application simulates Recorder interfaces 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 both ED137-4B and ED137-4C versions, as defined under EUROCAE (European Organization for Civil Aviation Equipment) Working Group 67. MAPS™ ED137 Recorder supports Real Time Streaming Protocol (RTSP) protocol for establishing, terminating and maintaining 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).

VoIP Air Traffic Monitoring System
PacketScan™ - an All-IP Network Monitoring software offers powerful features to capture and monitor live signaling and traffic over IP. It captures, segregates, monitors and collects statistics on all Ground-to-Ground calls and Air-to-Ground sessions. All data captured are forwarded real-time to NetSurveyorWeb™, a web-based centralized network surveillance system for air traffic monitoring. The application facilitates display of CDRs by connecting to multiple analysis probes such as PacketScan™ through a web server for monitoring physical layer, signalling and traffic. NetSurveyorWeb™ Lite is an addon to individual protocol analyzers enhancing capability to handle larger volume of data. The Lite version is a simple web-based client and works at the probe level, which is an easy plug-and-play system that collects data, segregates, and provides comprehensive analysis of network health, detailed protocol monitoring with historical data retention up to 9 GB.

MAPS™ TM-ATM – Critical Time Delay Measurements
MAPS™ TM-ATM (Timing Measurements in Air Traffic Management) tools includes all necessary hardware and software to identify, capture, timestamp, and correlate events at Analog, TDM and IP interfaces. This helps to precisely measure the delay introduced by each network element as events propagate end-to-end. MAPS™ TM-ATM tools can be deployed at appropriate strategic interfaces in a VoIP ATM network, to meaure network delay measurements such as: • Transmitter activation delay • Aircraft call indication delay • Ground transmission voice delay • Ground reception voice delay • Transmitter activation and aircraft call indication loopback delay • Ground transmission and reception voice loopback delay • Frequency key activation response time and more For more information on the capabilities of the Timing Measurement Tools in ATM, visit https://www.gl.com/delay-tests-voip-air-traffic-management.html webpage.
