详情描述

The HJ-E800C Digital Programmed Exchange is the most cost-effective new generation product in the E800 series. It integrates circuit and fiber optic access technologies to produce a new generation of digital programmed exchanges, supporting 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 the extension of remote modules via optical interfaces and E1 interface methods, making it an ideal device for users to improve communication conditions, enhance work efficiency, control phone bill expenditures, and implement office intelligence. It boasts user-friendly flexibility, high reliability, and large capacity. The system is widely used in business offices, factories, government agencies, hospitals, hotels, schools, and other corporate entities.

The HJ-E800C device features 1 MCU control and 16 user board slots, offering up to 128 voice phone lines.

The system supports up to 2 DT digital relay cards. Each DT card provides 1 E1 interface, which can be individually set as No.1, PRI, or No.7 signaling. The system can accommodate up to 64 loopback relay interfaces.
