NTP time server DTS 4163

SNTPPTPPRP

The DTS 4163.grandmaster is a PTP grandmaster specifically designed for IEC 61850 digital substations, providing precise time synchronization with redundant operation to increase reliability and availability.

Highlights

• PTP grandmaster optimized for IEC 61850 digital substations (PRTC / IEEE 1588-2008; compatible with IEEE 1588-2019 / PTPv2.1).
• PRP/HSR support for dual-attached node operation and seamless redundancy.
• Four fully PTP-capable Gigabit Ethernet ports (RJ45 or SFP) plus a dedicated management interface.
• Security features including secure boot, encrypted user data and signed firmware.
• High-capacity NTP server handling over 10,000 NTP/SNTP requests per second.
• Integrated multi-constellation GNSS receiver (GPS, Galileo, GLONASS, BeiDou, SBAS) for improved accuracy and availability.
• Boundary clock capability to bridge multiple time domains.
• Oscillator options (TCXO / OCXO / Rubidium) to enhance holdover performance.
• Legacy time outputs (IRIG, ToD, DCF, pulse, frequency) and event timestamping for integration with older systems.
• Full monitoring and management via MOBA-NMS.

Technical features (functional overview)
