ZMUX-4102 Solution

2.1  Introduction

Each remote node is installed with one set of ZMUX-4102 next-generation multi-service access transmission platform, and the integrated services such as VHF, ADS-B radar, synchronous radar and RCMS data of each node are uniformly connected and transmitted through the satellite IP circuit to the central node.

The central node installs 6 sets of ZMUX-4102 next-generation multi-service access transmission platforms, which respectively correspond to the ZMUX-4102 network communication of each node to realize the multi-service signal point-to-point communication function.

2.2  Features

1) Optional satellite IP circuit transmission

The traditional PCM device is based on E1 circuit transmission. The ZMUX-4102 platform provided by this solution can realize multi-service signal point-to-point communication function directly based on satellite IP circuit, support IP transmission delay optimization, jitter buffer absorption, anti-lost and other functions. It can improve IP transmission more stable and reliable, 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.

2) Support compression technology

The traditional PCM device's 1 channel VHF, synchronous radar or telephone occupy 1 channel 64K bandwidth. The ZMUX-4102 platform provided by this solution uses compression technology to compress the standard 1 channel 64K VHF, radar data and telephone into 9.6K bandwidth that can save satellite IP circuit bandwidth, save satellite line costs, and guarantee voice and data communication quality.

3) High security and reliability

The ZMUX-4102 platform has backup redundancy function from the working power supply, main control cross circuit, transmission link, and service port, support dual-master 1+1 protection, dual power supply 1+1 protection, dual transmission link automatic protection etc.

4) stable and reliable performance, good compatibility

The ZMUX-4102 platform has been successfully applied in the secondary radar transmission system of the Inner Mongolia Air Traffic Control Branch and the VHF transmission system of the Civil Aviation Tibet Bureau. The ZMUX series products have been successfully installed in many air traffic control, airport and maritime bureau users. It is used in conjunction with a number of well-known foreign radio stations, such as German R&S, British PAE, Italian OTE, American pioneer, Norwegian JOTRON, New Zealand TAIT, Japanese Kenwood, Australian Spectra, etc. The equipment is safe ,reliable, and the good compatibility.

The ZMUX-4102 platform is a plug-in card design. It can expand the service card to effectively meet the system business expansion in the future. Optional: VHF, synchronous radar, ADS-B radar, blind drop/navigation, DME ranging, DVOR Omnidirectional beacons, pointing beacons, non-directional beacons, meteorological self-contained data, automatic transfer data, weather radars, centralized monitoring data, and other air traffic control services.

6) One ground and one air protection transmission

The ZMUX-4102 platform can be switched between 1 channel air satellite line and 1 channel ground line automatic protection. The satellite IP circuit transmission is selected by default, and the ground E1 circuit interface can be reserved as a backup link to ensure the safe and reliable transmission of radar data.

7) Centralized monitoring function

The optional network management function can monitor the configuration information of the entire network ZMUX-4102 platform, the status of the transmission link, the link protection status, and the status of the service port.
