Remote Receiver Mute/Unmute confirmation.Main/Standby Tx/Rx transfer confirmation.End-to-end voice delay for PTT, and Squelch.Push To Talk (PTT), PTT confirmation, PTT release, PTT release confirmation.The MAPS™ program runs on Windows® operating system and uses the PC’s network interface card to send and receive traffic. MAPS™ can emulate a wide range of telecom protocols including ED-137 Radio, Telephone, and Recorder. This TM-ATM solution is based on GL’s Message Automation and Protocol Simulation (MAPS™) software program. TM-ATM solution includes all necessary hardware deployed across the Air Traffic Management network and software to identify, capture, timestamp, and correlate events at Analog, TDM, and IP interfaces. GL ‘s Timing Measurements in Air Traffic Management (TM-ATM) test suite accurately emulates endpoints in ATM networks and provides critical timing measurements for various types of delay occurrences in signaling and voice transmission. Delay measurements should be conducted repeatedly to ensure that the device and network under test is performing consistently over time. Recognizing, capturing, timestamping, and correlating events at Analog, TDM and IP interfaces are necessary. Measuring the delay in hybrid ATM networks is critical to ensure clear and quick communication between air traffic controllers and pilots. “GL’s ED-137 and ED-138 Voice over IP Test Tools have been widely welcomed by Global Air Navigation Service providers and Radio/Gateway/Recorder companies who have found them to be essential tools during development, functionality testing, performance testing, factory acceptance testing, deployment and field testing”, said Vijay Kulkarni, CEO of GL Communications. The GL test tools for next generation ATM offer signaling and traffic emulation per the ED-137 standards, monitoring the quality of service per ED-138, and providing critical network delay and voice quality measurements. Components can be accurately tested for timing, performance, and functionalities. This includes the ability to emulate and load test equipment such as Controller Working Positions, Ground Radio Stations, Analog-to-IP converters, Gateways, and more. GL offers innovative solutions for testing next generation ATM networks. Our solutions are adaptable to various global standards. Gaithersburg, Maryland, USA - MaGL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their Air Traffic Management (ATM) test solutions for testing Analog, TDM, Ethernet, and IP communications networks. (Contains 7 tables.GL’s VoIP Test Solutions for Air Traffic Management We therefore recommend that the quality of language tests used in aviation be monitored to ensure they follow accepted professional standards for language tests and assessment procedures. We conclude that we can have little confidence in the meaningfulness, reliability, and validity of several of the aviation language tests currently available for licensure. This probably reflects a variation in the quality of the tests, in the availability of evidence to support claims of quality, and in low awareness of appropriate procedures for test development, maintenance and validation. Twenty-two responses were received, which varied considerably in quantity and quality. A questionnaire was developed, based on the Guidelines for Good Practice of the European Association for Language Testing and Assessment (EALTA, 2006), and sent to numerous organizations whose tests were thought to be used for licensure of pilots and air traffic controllers. Therefore, it was decided to conduct an independent survey of tests of aviation English, since the consequences of inadequate language tests being used in licensing pilots, air traffic controllers and other aviation personnel are potentially very serious. As part of that study, Internet searches for other tests of air traffic control identified a number of tests but found very little evidence available to attest to the quality of these tests. The Lancaster Language Testing Research Group was commissioned in 2006 by the European Organisation for the Safety of Air Navigation (Eurocontrol) to conduct a validation study of the development of a test called ELPAC (English Language Proficiency for Aeronautical Communication), intended to assess the language proficiency of air traffic controllers.
