2. Long-lasting, stable, and timekeeping architecture
   DNTS-9 Equipped with a high‑performance rubidium atomic clock timing unit, the device maintains highly accurate independent timekeeping even when satellite signals are lost. Standard features include dual redundant power supplies and multiple isolated Gigabit Ethernet ports; in the event of hardware failure, it enables millisecond‑level primary/backup switchover, completely eliminating the risk of network‑wide timing disruptions caused by a single device outage.

3. High-concurrency, multi-segment network synchronization adaptation
   Device Support  10 The device features an Ethernet interface, enabling the segregation of independent time‑synchronization segments for the transaction intranet, the clearing‑only private network, and the office‑management isolation network. Equipped with high‑concurrency‑optimized time‑synchronization software, it can reliably handle simultaneous time‑sync requests from over ten thousand terminals, while multi‑NIC traffic aggregation prevents intranet congestion.

4. Financial-grade security protection configuration
   The device incorporates multi-layered security management mechanisms, supporting three-tier administrator privilege levels, login password complexity checks, and access control via blacklists and whitelists. It employs Chinese national cryptographic algorithms to encrypt time‑sensitive transmission signals, and is equipped with comprehensive operation logs and time‑synchronization logs for traceability. Logs can be exported and retained on a scheduled basis, meeting the requirements of financial auditing and provenance tracking.

5. Centralized Intelligent Operations and Maintenance System
   Built-in, independently developed by Zhongxin Chuang DNTS Manager Centralized monitoring and management software, enabling the management of multiple devices. DNTS-9 Unified visual management of devices, supporting real-time monitoring of satellite signals, device operating load, and network port status; via email, SNMP 、 Syslog It supports multi-channel push of device‑status alerts, remote firmware upgrades, and batch parameter configuration, aligning with the unattended operations and maintenance model for financial data centers.

6. Smooth Leap Second Handling Mechanism
   Equipped with a self-developed smooth leap‑second algorithm, it can automatically align with the time‑sequencing logic of financial trading systems, preventing time jumps caused by leap‑second adjustments and enabling a seamless transition without requiring any modifications to the customer’s existing business systems.

VII. Implementation Outcomes

1. Synchronization accuracy meets the standard.
   The synchronization error of the network-wide servers, trading terminals, and storage devices is stably maintained within 2ms Within this framework, the transaction log and clearing transaction timestamps are uniformly aligned in chronological order, ensuring that after-hours reconciliation and cross-system data verification exhibit no temporal discrepancies, thereby fully complying with financial‑transaction‑time‑series regulatory standards.

2. Business operations remain consistently stable.
   Since the project went live, there have been no issues with time‑synchronization interruptions, clock drift, or network congestion. When the data center’s satellite signal is briefly disrupted by weather conditions or building obstructions, it relies on… DNTS-9 The built-in rubidium atomic clock provides a continuously stable output of standard time, ensuring the seamless operation of all business processes—from daytime market opening to overnight settlement.

3. Implementation of Indigenous Innovation Security and Compliance
   The equipment supports a pure BeiDou time‑synchronization mode, with all core hardware and timing algorithms developed domestically through independent research and development. It is backed by a comprehensive security‑audit framework, has successfully passed the information‑security compliance review conducted by Fullgoal Fund, and has completed the domestic‑innovation upgrade of the data center’s time‑synchronization infrastructure.

4. Enhanced Operations and Maintenance Management Efficiency
   Through DNTS Manager The unified platform enables centralized management and control of multiple clock servers, while remote alarm notifications and batch log export features reduce the frequency of on-site data center inspections, significantly lowering operational and maintenance labor costs. Comprehensive historical time‑synchronization logs are retained, providing rapid support for regulatory audits and root‑cause analysis of service incidents.
