Zhongxin Chuangwei provides clock synchronization server equipment to Ningxia Radio and Television Station.

Zhongxin Chuangwei provides clock synchronization server equipment to Ningxia Radio and Television Station.

Recently, Ningxia Radio and Television Station issued a request for a time server. Beijing Zhongxin Chuang Company promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑7 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 Beidou timing equipment project at Ningxia Radio and Television Station.

Ningxia Radio and Television Station (English abbreviation: NXTV) operates five major media platforms—radio, television, newspapers, a cable TV network, and a website. Established in December 2004, it is a public institution directly affiliated with the autonomous region government and jointly managed by the Publicity Department of the CPC Ningxia Hui Autonomous Region Committee and the Administration of Press, Publication, Radio, Film, and Television.

Ningxia Radio and Television Station conducted an in-depth evaluation of the DNTS-7 time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the station expressed high satisfaction with both our product quality and after-sales service, proceeding to place a successful order and put the system into operation.

The DNTS-7 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-7 obtains standard time information from systems such as GPS, BeiDou, GLONASS, Galileo, 4G, and CDMA, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time.

When using GNSS satellite receivers simultaneously, priority can be configured; the system supports single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations, with each receiver capable of operating in standalone or combined timing modes.

The DNTS-7 features 1 to 4 adaptive 10/100/1000 Mbps Ethernet ports, with physical isolation between ports to ensure data security. All ports can be configured on the same network segment or on different segments, providing redundancy—failure of one port will not affect the normal operation of the others. Each Ethernet port must be assigned a unique IP address.
