Enhancements to VoIP ATM Test Solutions
8th, Mar 2019
Welcome to GL’s another March 2019 Newsletter providing information on our test solutions for smooth transition of services from traditional Air Traffic Management (ATM) to IP based Voice Communications (VoIP).
A traditional Air Traffic Management (ATM) can be migrated to IP based voice communications (VoIP) for providing better and efficient services, and challenges to ensure reliability, and performance. GL offers customized solutions for testing Air Traffic Services Ground Voice Network (AGVN), which includes ability to simulate all the entities, from the radio interfaces to the Controller Working Position (CWP), and remotely monitor the network response with various test scenarios.
The migration to Voice over Internet Protocol (VoIP) poses challenges, which requires a customized test solution, the ATM core network and all its underlying entities (CWP/VCS, GRS, Radio Gateways and Recorders) can be accurately tested for timing, performance, and functionalities. The GL test tools for next generation Air Traffic Management (ATM) offer signaling and traffic simulation per ED-137, monitoring quality of service per ED-138, critical network delay and voice quality measurements.
Our ED-137 and ED-138 Voice over IP Test Tools have been widely welcomed by Global Air Navigation Service Providers and VCS/Radio companies alike, who have found them to be essential tools during development phase, functionality testing, performance testing, Factory Acceptance Test phases, deployment phase and for 'in-the-field' testing.
Below is a typical Air Traffic Management network showing the role of emulators and analyzers. As you can see, we can simulate air-to-ground, ground-to-ground and recorder interfaces as per ED-137 standards. Complete network can be probed using PacketScan™ and analyzed either locally or remotely using NetSurveyorWeb™ applications.
GL’s VoIP ATM Test Solution includes Emulators and analyzers deployed across the Air Traffic Management network, which are briefly discussed below -
MAPS™ ED-137 Radio simulates air-to-ground calls by emulating either CWP/VCS or GRS. MAPS™ emulator supports both version B and C of ED-137 volume 1 Radio. Hundreds of CWPs or Radios can be simulated and can generate bulk air-to-ground calls using a single instance/license. Can be used to test functionality and performance of CWP, VCS, GRS and Radio Gateways.
MAPS™ ED-137 Telephone simulates ground-to-ground calls by emulating CWP/VCS. Supports both version B and C of ED-137 volume 2 Telephone. Hundreds of CWPs can be simulated and can generate bulk ground-to-ground calls using a single instance/license. Can be used to test functionality and performance of CWP/VCS.
Latest enhancements include -
MAPS™ ED-137 Recorder is used to simulate Recorder interface at VCS, GRS and Recorder server as per version B of ED-137 volume 4 Recorder. MAPS™ emulator can be configured as either CWP or GRS or Recorder to simulate recorder interface at that node. Hundreds of CWP/GRS/Recorders can be simulated.

PacketScan™ is an all-IP Network Monitoring software, which offers powerful features to capture and monitor A-G and G-G calls in the ATM network. The application can capture, segregate, monitor and collect statistics such as Packet loss, delay, jitter and MOS scores on all the captured calls. It can also act as a probe in the network and send Call Detailed Records to a centralized database.
NetSurveyorWeb™ Lite is a web-based client application, which facilitates real-time data display, navigate through historical records (9 GB of CDR storage), filter the collected VoIP traffic summary, and graphically analyze the call volume, MOS (Mean Opinion Score), Packet loss, failed calls, completed calls, Post Dial Delay, and more. NetSurveyorWeb™ Lite version can be deployed on the Probe (PacketScan™) system with limited database on the same system.
TM-ATM Solution (Timing Measurements in Air Traffic Management) is a custom suite of test tools designed to accurately measure various types of delay occurrence in signaling and voice transmission. It includes all necessary hardware and software to identify, capture, time stamp, and correlate events at Analog, TDM and IP interfaces.
