- Commodity name: HJ-E800C Digital Program-Controlled Switch
The HJ-E800C digital program-controlled switch is the most economical new generation product in the E800 series. It integrates technologies such as circuit and fiber optic access to develop and produce a new generation digital program-controlled switch. It supports analog trunks such as loop, E&M, and carrier, as well as digital trunks with protocols like No.7, R2 (NO.1), PRI, and V5 signaling; it supports remote module extension via optical interface and E1 interface. It is an ideal device for users to improve communication conditions, enhance work efficiency, control call expenses, and implement office intelligence. It features ease of use and 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-E800C device is controlled by one MCU and has 16 user board slots. It can provide up to 128 voice telephone lines.
The system supports up to 2 DT digital trunk boards. Each DT provides 1 E1 access, and each E1 can be individually set to NO.1, PRI, or NO.7 signaling. The system supports up to 64 loop trunk interfaces.
1. Large Capacity
The system provides 2 E1 interfaces, 64 loop relays, and supports 128 voice ports.
2. Powerful Functions
This device features powerful call processing, billing, centralized network management capabilities, with redundant backup for the main control board and power board to ensure uninterrupted communication.
3. Strong Networking Capabilities
Provides interfaces such as E1, E&M, carrier, magnet, loop, and fiber optic. E1 supports signaling protocols including R2, NO.1, DSS1 (PRI), QSIG, SS7, and V5. Various interfaces and signaling can be interconnected and can serve as signaling and interface gateways.
4. Remote Modules
Supports fiber optic or E1 remote module extension, greatly reducing manual wiring costs and simplifying maintenance.
5. Highly Reliable Performance
Fully distributed control, modular structure, utilizing DSP and FPGA technologies, K20 level 3 lightning protection measures, fault diagnosis and detection functions, and hot-swappable technology.
6. Wide Range of Applications
Suitable for carrier access, private network networking, virtual operation, government agencies, hotels, enterprises and institutions, dispatch communication, call centers, alarm receiving platforms, and other communication applications.
7. Control System
Embedded technology-based on-chip processing system, large-capacity NAND FLASH storage, supports online program upgrades.
8. Digital Audio Source System
Provides personalized extension ring-back tone services, hierarchical IVR voice guidance, and voice mailbox services.
9. Voice Mailbox Function
This voice mailbox system independently completes all voice mailbox functions without a computer; uses flash as storage medium, supporting a total of 255 mailboxes. Mailboxes 0–64 can record up to 16 minutes of voice, mailboxes 65–255 can record up to 4 minutes; each mailbox can individually record a welcome message up to 16 seconds; supports simultaneous recording of 32 voice mailboxes. Fully digital recording with G.711 standard audio quality, providing telecom-grade call quality. It offers a perfect solution for voice mailbox systems in hotels and small to medium enterprises.
10. Board Fault Detection
Advanced hardware board fault monitoring function with automatic fault shielding; the board operation status can be fully viewed in the backend.
11. Low Power Control
The system greatly reduces the number of backup power batteries and overall power consumption while ensuring normal call line operation.
12. Reasonable Structure and Flexible Configuration
Fully digital, full time-slot seamless switching network; unit modules centered on the switching network with unified unit interfaces to ensure interchangeability of different units; true universal slots allow various interface boards to be set arbitrarily, and capacity can be adjusted freely according to user needs, configuring extension/trunk ratios arbitrarily to maximize system resource sharing.
13. System Structure
19-inch standard rack-mounted structure, elegant and beautiful appearance.
