Overview
At present, IP-based data services are rapidly developing. At the same time, many networks and services are converging around IP technologies. As a multi-service platform, IP networks are the trend of network development, and various broadband IP access technologies are emerging. And fierce competition, in the big open environment of the telecom operation industry, the competition of access networks, especially IP access networks, is particularly fierce.
Domestic civil aviation began to promote the application of multi-service transmission technology based on IP network, and strive to build a communication network integrating ground and air, continuously improve the layout of ground facilities and network construction, and improve the safety level, operational efficiency and service capacity of civil aviation as a whole, and increase Airspace capacity.
Solution
Guangzhou Yinxun Company proposed a new generation multi-service access and transmission platform to meet the application requirements of airport air traffic control users. It realized 64K narrowband services and broadband unified access, aggregation, switching, transmission and management requirements of data services through IP circuit, E1/2M circuit, optical fiber or SDH line. In addition to providing various traditional narrowband service interfaces and modern broadband service interfaces, also reserve the ability to smoothly upgrade for future business needs. The system's built-in high-capacity cross-matrix and high-throughput packet-switching processing module make the distribution scheduling of services in the network extremely convenient. The application of large-scale SOPC (system on a chip) technology makes the platform self-updating and upgrading.
In this way, both the existing investment of the user is protected, and the new technology is continuously introduced, so that the platform always maintains the technological advancement and is suitable for the current development trend of the IP transmission network.
Multi-service access and transmission
The remote station and the central station lease the IP circuit of the operator, and the remote service signal is connected to the ZMUX-4102 platform, and transmitted to the central office through the IP circuit to complete the multi-service signal communication and transmission function. It is compatible with VHF, radar data, meteorological data, blind drop navigation data and other common services for airports and air traffic control.
Dual route transmission protection
The traditional E1 (TDM) transmission network and equipment have ensured the safe and stable operation of the civil aviation communication system for many years. In the process of gradually establishing and perfecting the IP system, the E1 line becomes the final security backup, which is very necessary.
The service of some remote stations is very important. It is recommended to rent the E1 circuit of the operator and form a dual route protection transmission system with the IP circuit. The E1 line and the IP private line are recommended to be accessed in two directions, and space disasters are considered to avoid the occurrence of simultaneous interruption of the 2 channel ground line.
Ground-to-air transmission protection
Some remote stations can construct 1channel wireless 4G line as an alternate transmission route to ensure that the ground line can be transmitted over the air line due to the force majeure interruption, ensuring the safe and reliable transmission of important services such as radar and VHF etc.
The wireless 4G mode needs to use 4G traffic to realize communication transmission. The ZMUX-4102 provided by Guangzhou Yinxun Co., Ltd. has 4G flow control function. When ZMUX-4102 monitors the data flow of radar, VHF and other service ports, it starts wireless 4G transmission. When the ZMUX-4102 monitors the service port with no data stream, it only transmits the necessary handshake signals and device monitoring signals.
IP transmission is stable and reliable
The ZMUX-4102 can perform unified scheduling and configuration on the accessed service signals, and can set important service priorities to ensure that each service signal has stable bandwidth and does not affect each other, ensuring stable and reliable transmission of important services.
ZMUX-4102 supports IP transmission delay optimization, jitter buffer absorption, anti-drop packet and other functions to improve the stability and reliability during transmission, and to solve the problem of inconsistency, delay and even interruption in VHF voice communication.
