Zhongxin Chuang has provided an NTP time server to the Eighth Research Institute of China Electronics Technology Group Corporation.

、

Recently, the Eighth Institute of Electronics issued a requirements specification for a clock synchronization system. Beijing Zhongxin Chuang Co., Ltd. proactively collaborated to develop a detailed solution and recommended its self‑developed and manufactured DNTS‑8 time server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the Eighth Institute of Electronics’ clock synchronization equipment project.

The Eighth Research Institute of China Electronics Technology Group Corporation, also known as the Anhui Institute of Optical Fiber and Cable Transmission Technology, was founded in 1970. It is one of China’s earliest national first-class research institutes dedicated to the research, development, and application of optical transmission technologies.

The Eighth Institute of Electronics’ independently developed by Zhongxin Chuang DNTS-8 Type clock The servers underwent thorough testing, and the results consistently exceeded the specified performance parameters. Furthermore, our company’s product quality and after-sales service were highly praised, leading to a smooth procurement and successful deployment.

The DNTS-8 time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high precision. The DNTS-8 time server acquires standard clock signal information from GPS or BeiDou geostationary satellites and transmits this information across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize with the standard clock. When both GPS and BeiDou receivers are in use, a priority can be defined; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver has a signal, the DNTS-8 relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-8 disseminates standard clock information over TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as Zhongxinchuang’s proprietary time‑broadcast data packets with configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC-123 and RFC-37. Additionally, the DNTS-8 supports the broadcast mode of the SNTP protocol.
