a) Adoption of Localized and Independently Controllable Technologies

All components of the equipment, including FPGA chips, microprocessors, interface chips, discrete components and connectors, are selected from mature products of domestic manufacturers.

b) Dual-bus Architecture for Enhanced Scalability and Flexibility

The equipment adopts a dual-bus architecture of 2.5G SDH and Gigabit Ethernet. The dual buses run through all user slots of the equipment. Service transmission, reception and decomposition can be implemented via the SDH bus and Gigabit Ethernet bus on demand, which greatly improves the flexibility, reliability and transmission efficiency of the equipment's service interface configuration.

c) Flexible Configuration and Hot-swappable Architecture

With the objectives of achieving integration, high availability, high reliability, high credibility, scalability and flexible configuration for the integrated multi-service transmission equipment, the overall architecture of the equipment is designed in compliance with such features as board hot-swapping and flexible configuration during the R&D phase. It adopts an intelligent chassis management method based on a custom high-speed bus. Through highly integrated hardware design and in-depth hardware-software adaptation, the system is endowed with capabilities of easy upgrade, easy maintenance, easy support and scalability.

d) Programmable Devices for Core Logic Functions

Domestic large-scale FPGA devices are mainly adopted in the solution design to implement digital logic circuit functions. The application of large-scale FPGAs can significantly reduce the use of dedicated chips, which is conducive to the localization of products and the component availability in the production process, reflecting the advancement of this technical solution.

e) Fully Enclosed Fanless Conductive Cooling Design

The fully enclosed fanless conductive cooling design reduces the equipment size, greatly improves the environmental adaptability and reliability indicators of the equipment, and significantly lowers the equipment noise level.

f) Dual Redundant Hot Backup Design

Both the power supply module and the main control module adopt a dual redundant hot backup design, which substantially enhances the operational reliability of the equipment.

g) Modular and Serialized Design

A series of universal modules are designed, and serialized products with different functions and performance indicators are formed through the combination of different modules. The equipment chassis allows various modules to be inserted into any transmission/service slot. Users can adjust the configuration of transmission modules and service modules at any time according to actual application scenarios, thereby reducing the procurement of new equipment and demonstrating excellent economic efficiency.

h) Front Maintenance and Rear Cabling Architecture

All equipment modules support front-side plugging and unplugging for convenient maintenance; all interfaces adopt rear-side cabling, which is conducive to vehicle-mounted or equipment room installation, featuring excellent practicability.

i) Compliance with Relevant National Military Standard (GJB) Requirements

The equipment complies with relevant GJB requirements for vibration, shock, damp heat, insulation resistance, dielectric strength, leakage current, electromagnetic compatibility, etc.
