It is an ideal device for users to improve communication conditions, enhance work efficiency, control call expenses, and implement intelligent office automation. It features ease of use, flexibility, high reliability, and large capacity. The system is widely used in business offices, factories, government, hospitals, hotels, schools, and other enterprises and institutions.
The HJ-E800B device adopts a modular design, composed of 1 to 8 modules. Each module is controlled by one MCU and has 16 user board slots. A single module supports up to 256 user interfaces, and the entire device can provide a maximum of 2048 voice telephone lines.
The system supports up to 9 DT digital trunk boards. Each DT provides 4 E1 accesses, and each E1 can be individually set to NO.1, PRI, or NO.7 signaling. The system can support up to 36 E1s and 1024 loop trunk interfaces.
The device supports two MCU/SCU main control boards. One MCU/SCU controls the operation of the entire device, while the other MCU/SCU serves as a backup main control board. When the first MCU/SCU fails, it can automatically switch to the second MCU/SCU for operation. The system's PWR power board has dual backup, supporting dual backup for operating voltage and ringing current, as well as fault detection.
- 19-inch rack-mounted standard single 6U chassis, supports 256 single-frame analog extensions, maximum support for 2048 IP extensions, dual main control redundancy hot standby, AC voltage AC110V-AC240V, DC voltage DC48V dual input power supply system, mixed insertion of internal and external line slots.
- Can provide users with basic and enhanced functions of a centralized user switch:
- Basic services: can provide intra-group calls, inter-group calls, malicious call tracking, operator functions, intelligent incoming call matching, remote optoelectronic extension functions, wake-up service, distinctive ringing, incoming call transfer, call answering on behalf, and other functions.
- Main required services: abbreviated dialing, hotline service, call detail record support, do not disturb service, alarm clock service, interception service, call waiting, malicious call search, busy/no answer/unconditional forwarding, busy callback, outgoing call restrictions, absent user service, immediate billing, three-party calls, 128-party conference calls, caller ID display, caller ID display restrictions, voicemail, and over 200 blacklist settings.
- The system is required to have a maximum user capacity of no less than 2048 lines, maximum trunk capacity of no less than 1024 lines, support No.7/PRI/No.1 signaling, and magnetic trunk. The switching system should have strong upgrade capabilities, allowing smooth online addition of new system functions without affecting call processing.
- Meet the demands for continuously increasing various value-added services (new services).
- The quoted switching equipment must have high reliability, with main equipment adopting hot standby backup mode (main control board, secondary power board, sub-control board).
- The system composition should have redundancy and fault tolerance safety measures, support CPU dual backup, dual backup for each frame's sub-control board, dual backup for each frame's secondary power supply, and each power module supports independent 48V input.
- Support MYSQL database, EXCEL import and export, WIN7 system, and automatic user data backup.
- To optimize data center resources, provide the most advanced technical solutions. The main data center's main equipment system (digital program-controlled user switch) supports direct fiber/E1 connection with remote PCM. The main equipment system has built-in PCM cards, which can have 1 to 4 E1 interfaces or 1 to 4 optical ports, corresponding to 1 to 4 remotes respectively. Each PCM card supports a maximum of 256 extension lines.
- The main equipment system supports simultaneous management via Ethernet and serial ports, and through the network interface supports 8 soft seats.
- Remote end supports E1 interface and optical port 1+1 protection.
- Remote modules can be expanded with 10/100M Ethernet interfaces.
- Central and remote ends support remote online upgrades.
- Supports emergency systems such as disaster escape, emergency evacuation, evacuation, alarm, SOS emergency rescue, etc. Supports equipment fault early warning.
- Supports SIP voice encoding, fax protocols G.711, G.729, T30, T38, etc.; supports VOIP protocols: SIP/H.323, MGCP/H.248.
- The entire system (including remote) achieves unified network management, supports maintenance consoles, operator consoles, billing consoles management, supports PC soft operator consoles, IVR navigation system, wake-up service system, voicemail, night service system, malicious call tracking system, disaster escape system, SOS system, report statistics system, PMS docking system, and conference system.
