Press Release: GL's ED-137 Radio Emulator Connects to Live ROMATSA Radio at World ATM Congress
Gaithersburg, Maryland, USA – March 21, 2016 - GL Communications Inc., announced today
it’s MAPS™ ED-137 Radio Emulator successfully connecting to Live ROMATSA Radio to test VoIP ATM system at World ATM Congress held recently at Madrid, Spain.
Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for Product Development of company, said, “At the recently held World ATM Congress event in Madrid, Spain, the GL’s MAPS™ Radio Emulator capability was showcased. It was connected to a Rohde & Schwarz radio located in Romania with the help of the Romanian Air Traffic Services Administration Staff (Romatsa). This radio is responsible for a certain sector of the Romanian airspace.
The ED-137B connection was made, with the GL’s MAPS™ Radio emulator in “RX Only” mode. Any airplane communication (squelch break) from an airplane in that sector was heard by our tool. The ED-137B connection was also monitored with GL’s PacketScan™ which was able to show (in real-time) all of the voice and packet characteristics of this connection. Visitors seemed particularly interested in the real time Waveform viewer and MOS/Jitter etc. value measurements.
Similarly GL's MAPS™ Radio Emulator can also be connected and tested seamlessly with other Radio vendors like Jotron, Park Air, and more.”
He added, “Visitors at the World Congress could see for themselves how easy it was to configure and run the application in order to establish SIP sessions to the radios, examine either the high level protocol exchanges or the in-depth protocol content as well as listen to the live controller voice on the Rx-only channels established to the radios. The emulator’s Human Machine Interface (HMI) has been designed to allow users to easily configure profiles of the CWPs, observe the status of the session(s) during establishment as well as when active and also allows the change of RTP Extender settings on-the-fly during an established session.”
Mr. Vadalia further explained, “GL’s MAPS™ ED-137 Radio Emulator application running on a PC is able to emulate either a single/multiple Controller Working Positions within a Control Centre or a single/multiple Radios at different remote sites.
Developed per EUROCAE WG67 ED-137B documents, the Emulator is set to become the benchmark emulator for Air Navigation Service Providers (ANSP) as well as Voice Communication System and Aeronautical Radio vendors operating in the field. The extra built-in functionality of an impairments generator was seen as an added advantage of the tool by ANSP network designers, wanting to verify the limits of their network with respect to packet loss, latency and jitter.
Besides the emulator products, ANSP’s particularly appreciated the GL PacketScan™ application that is able to measure not only Voice Quality MOS values in real time over multiple established sessions, but also latency, jitter and packet loss values as well as raise alarms when measured values exceed the limits set by EUROCAE WG67 ED-138 document. Tools like these especially designed for ANSP specific requirements are essential as the World’s Air Traffic Management voice networks migrate towards IP. But it is imperative that before such a system is deployed live, thorough testing for delay, noise, voice quality, performance, reliability, and other critical functionalities be performed.”
He added, “GL’s tools provide for testing of such critical functionalities like signaling and traffic simulation, monitoring, and voice quality testing over an end-to-end test solution for testing any point in ATM network, from the Radio interfaces to the Controller Working Position (CWP).
GL's Test Solutions provide the necessary flexibility and enhancements to meet the challenge of ED-137B. And as standards evolve, GL will track and provide updates as well.”
