Product Advantages:


1. System architecture and hardware reliability


● Distributed modular structure, fully decentralized load-sharing operation, each module is relatively independent, with low fault correlation and impact scope, and faults between same-level modules do not affect each other.


● Public hot backup redundancy design ensures high availability of the main CPU, switching network, clock, signaling equipment, power supply, and communication links. The main and backup motherboards, as well as power switching, do not affect other components. The switching process will not interrupt the current call lines.


Low power consumption and energy-saving, the entire unit is composed of high-integration, low-power integrated circuits and electronic components. The unit operates in low-power mode under normal circumstances, and only the corresponding extension will enter working state during off-hook calls, achieving energy-saving and power-saving effects.


● Utilizes ultra-large-scale communication dedicated chips, dedicated DSP digital signal processing chips, FPGA programmable logic chips, etc., ensuring the system's low power consumption, high efficiency, long lifespan, and high reliability.


● Messages are never lost, as the system utilizes a high-capacity Flash message storage system, capable of storing an extensive amount of messages.


● Enclosures, back panels, and various circuit boards are designed with standardized, universal specifications to enhance compatibility and anti-interference capabilities.


All circuit boards support hot swapping.


● Reasonable component derating design and strict aging screening.


● The user repeater unit strictly employs a three-level lightning protection circuit.



2. Highly integrated and scalable


The system boasts high integration capabilities:


1) Voice communication supported: Basic program controlled voice exchange scheduling technology.


2) Supports video interlinking: Real-time video interlinking for multimedia dispatching.


3) Supports built-in broadcasting system: enables scheduled broadcasting, group broadcasting, task process broadcasting, and MIC broadcasting announcements, etc.


4) Built-in alarm system supported: one-touch alarm, central station forced alarm, etc.


5) Supports built-in full-channel recording system: Records all types of communication channels, including internal and external lines, conferences, broadcasts, and all other communication channels.


6) Supports built-in cluster gateway system: Access different frequency radio stations, allowing the dispatch center to easily schedule radio intercom functions for each station.

3. Real-time monitoring ensures system stability


Robust self-diagnostic card monitoring with fault alert and graded fault handling capabilities.


● Comprehensive centralized monitoring and maintenance features, with graphical, user-friendly maintenance operations.


Complete monitoring of in-line and off-line communication status, with real-time recording of information.


● Real-time engineer online remote assistance.



4. Software Reliability

Developed graphical software and WEB-based convenient management backend with multiple maintenance platforms based on Windows.


● All important data is protected with access control and tiered protection. Additionally, backups are in place for critical programs and data.


● Standardize communication messages and conduct rigorous rule checks and error verification.



5. Redundant design


(1) The mainboard CPU system supports both master and backup operation modes.


(2) Both the primary and backup parties can monitor each other, as well as the current working status of each motherboard. Should a motherboard fail, the backup (standby) party will automatically switch to the primary (active) status, and the motherboard in active status will continue to operate.


(3) The switching network employs a non-blocking fourth-generation ultra-large-scale digital switching network.


(4) The clock/sync circuit operates in a master and standby mode as well. It can automatically switch during faults and also features manual switching capabilities.


(5) Power supply is implemented using dual parallel supplies by frame, with both primary and secondary power sources operating in a 1+1 dual hot standby mode.



6. Advanced circuit design philosophy


(1) To enhance the system's anti-interference capability, measures taken in electromagnetic compatibility design include: separating power and ground lines, segregating high-speed and low-speed signal lines, matching input/output impedance, and strengthening grounding, filtering, and shielding.


(2) To enhance the system's adaptability to the environment, the following measures have been taken in terms of environmental resistance design: The user circuit is equipped with primary overvoltage and overcurrent protection, as well as secondary protection, and features an overvoltage automatic recovery function. Both overvoltage and overcurrent protection designs comply with ITU-T Recommendation K20 requirements. Corresponding measures have also been implemented for anti-corrosion, anti-high temperature, and vibration resistance.


(3) Choose ARM and DSP chips with large-scale and ultra-large-scale integration and strong voice processing capabilities.


(4) Individual circuit boards are interconnected via connectors with the rear panel of the frame.


(5) Employed multi-layer common backplanes; the single board bus interfaces are designed with the same dedicated chip.
