二、Overview

Voice Communication System is connected to the voice and control signals of VHF radio and telephone respectively, providing the airport air traffic control department (ATC) with a fast, convenient and highly reliable voice communication system (VCS), which is convenient for multi seat controllers to dispatch, command, use and manage the working frequency of multi-channel VHF radio, as well as multiple telephone communication scheduling.

The system is a soft switch distributed architecture, which ensures the interconnection of the system in reliability, sound quality, delay and other key parameters in design.

三、Advantages

1. High Reliability: dual IP systems are independent and parallel, distributed call control, independent dual networks, isolated internal and external networks, redundant design, etc., to ensure that equipment has 99.9999% high reliability and availability.

2. Sound Quality Is Good: seat terminal, telephone board (CO), trunk board (PSTN) and other boards support echo cancellation algorithm to effectively reduce and eliminate spatial echo and line echo. EQ equalization processing is used to ensure that the voice of the controller is soft and the voice is clearer and fuller.

3. Lower Delay: ultra short packet switching is adopted, PTT response time ≤ 10ms, transmission delay from seat audio to radio interface board (IDF): analog radio ≤ 30ms, IP digital radio ≤ 15.5ms.

4. Strong Scalability: The system can be expanded by adding boards, plugins, cabinets, etc. It is very convenient to add hardware configurations through modular design.

5. Interconnection: meet the requirements of analog/digital radio, voice recorder, PSTN， The communication connection between VCS systems meets the specification requirements.
