The military camp communication project of Shenzhen TL camp of a PLA unit includes the convergence switch of the central computer room, the core switch and the corridor switch of multiple buildings. Among them, the aggregation switch and core switch are required to support BPDU protection, root protection, loop protection, support multicast group strategy and multicast group quantity limit, support cross VLAN replication of multicast traffic, achieve unified management of a single IP for the entire virtual system, and make actual physical devices transparent to users, simplifying the management of network devices and network topology.
The military camp adopts the core switch X52624-B-E, aggregation switch X51424-M, and access switch X31216 of the Xallco to jointly form a three-layer communication topology structure. Through unique virtualization cluster switching technology, multiple physical switches are virtualized into a logical device. The performance, reliability, and management of its virtual system have the advantages of doubled performance, high reliability, and easy management compared to independent physical devices. interconnected system

The communication part of the military field comprehensive communication vehicle mainly includes three parts, namely wireless communication equipment, wired communication equipment, and power supply equipment. Communication vehicles must have good lightning protection design. During outdoor operation, due to the influence of antennas, signal transmission, etc., they are easily affected by lightning strikes in severe weather, which not only poses a great threat to the safety of equipment and personnel, but also affects the quality of communication signals. At present, military communication vehicles must support various functional features such as wireless communication, wired communication, high-speed bandwidth, high-definition video, voice, encryption, and anti-interference for field communication.
The communication vehicle of a certain branch of the army adopts the X4F04 and X4S04 communication modules from Xallcom as the core components to form a programmable magnetic telephone exchange system, which realizes functions such as feeding, overvoltage protection, ringing, monitoring, encoding and decoding, mixing, polarity detection, 24 line conversion, loop control, on hook transmission, and incoming call display. It has strong confidentiality, low heat generation, wide temperature operation, stable functions, and maintains high fidelity of voice call quality.
