Congratulations to Zhongxin Chuang for winning the bid for the DNTS‑8 type time synchronization equipment of the Northern Pipeline Company of China National Pipeline Group.

Congratulations to Zhongxin Chuang for winning the bid for the DNTS‑8 type time synchronization equipment of the Northern Pipeline Company of China National Pipeline Group.

Recently, the Northern Pipeline Company of China National Pipeline Group Co., Ltd. issued a procurement announcement for time servers. Beijing Zhongxin Chuang promptly collaborated with the client to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑84 model 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 time server project from the Northern Pipeline Company of China National Pipeline Group Co., Ltd.

The business scope of China National Pipeline Group Northern Pipeline Co., Ltd. includes subsea pipeline transportation, pipeline transportation, road transport of general goods, research and development of oil and natural gas pipeline technologies, technical consulting and services for pipeline storage and transportation projects, maintenance, overhaul, and technical services for compressor units (engines and compressors), technological development, technology transfer, technical consulting, and technical services related to oil and gas storage and transportation as well as product testing, computer software development and maintenance, data processing services, information system integration and IoT technical services, the sale of electronic products, computer hardware and software, and auxiliary equipment, leasing of buildings and premises, pipeline engineering construction, tendering and bidding agency services, and specialized cleaning, washing, and disinfection services. In addition, the following activities are conducted by its branch institutions: repair of metal products, machinery, and equipment; and crude oil storage. (For projects that, according to law, require approval, business operations may only be carried out upon obtaining approval from the relevant authorities.) China National Pipeline Group Northern Pipeline Co., Ltd. has 27 branch offices.

China National Pipeline Group Northern Pipeline Company Ltd. conducted an in-depth evaluation of the DNTS‑84 time server independently developed by Zhongxin Chuang, and the results all exceeded the specified performance parameters. The company also expressed high satisfaction with our product quality and after-sales service, resulting in a successful procurement and deployment.

The DNTS-84-OGB 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-84-OGB 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 configured; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver receives a signal, the DNTS-84-OGB relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-84-OGB disseminates standard clock information over TCP/IP networks and supports multiple popular time‑distribution 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-84-OGB supports the broadcast mode of the SNTP protocol.

Network Protocol:	NTP v1, v2, v3, and v4 (RFC 1119 and RFC 1305) SNTP (RFC 2030) MD5 Authentication (RFC 1321) Telnet (RFC 854) UDP NTP Unicast, Broadcast, Multicast, Autokey TIME (RFC 868) FTP (RFC 959) DAYTIME (RFC 867) DHCP (RFC 2131)

Time-keeping management software performance
Client-side time synchronization software:	Provides NTP‑based time‑synchronization software for Windows, running as a service and offering a monitoring, control, and configuration interface. The client supports operating systems including Windows 98, NT, 2000, XP, Vista, 7, Unix, Linux, AIX, and others.
DNTS-Manager Network Time Synchronization System Monitoring Software:	Provides timing‑monitoring software for NTP servers and clients, enabling the monitoring of synchronization and time‑offset status on both NTP servers and timing clients, with alert and log generation. Alerts can be delivered via protocols such as Syslog and email. The system supports simultaneous monitoring of at least 1,000 NTP servers and no fewer than 10,000 client devices. Monitoring includes NTP server information—such as uptime, synchronization status, and network parameters—as well as NTP server time‑synchronization status, encompassing satellite time, server time, and synchronization with reference sources. Features also include management of server and client lists, threshold settings, and configuration options for email and Syslog notifications, along with delivery‑status controls.
