VelaSync 1232 High Speed Time Server

Spectracom VelaSync 1232 High Speed Time Server

10/25/40 GbE High Performance PTP Grandmaster and NTP Server

VelaSync™ 1232 high speed time server is a network appliance designed for high frequency trading and other low-latency network applications. The combination of VelaSync's highly optimized timing protocols and management functions, Spectracom’s precision GPS timing technology and the flexibility of commodity hardware offers exceptional performance and keeps pace with the needs of evolving network infrastructure.

  • PTP + NTP on all ports
  • Low 100’s of nanoseconds accuracy
  • 1G/10G/25G/40G Ethernet
  • I/O Support for 1PPS, IRIG
  • Multi-GNSS support (GPS, Galileo, GLONASS, Beidou)
  • Rubidium atomic clock option
  • STL sync option for infoor timing or augment GNSS
  • BroadShield GPS jamming and spoofing detection option
  • Advanced user interface and REST API
  • Secure network management; enable or disable protocols for encryption, authentication, authorization and accounting
  • IPv4/IPv6 dual stack
  • Dual redundant and hotswappable AC power supplies and hard drives

Spectracom VelaSync 1232 High Speed Time ServerFlexible Configuration Provides Reliable, Secure Time

The VelaSync 1232 web-based user interface simplifies the configuration of multiple time sources for resiliency against GPS jamming or spoofing attacks, network issues and equipment failures. For example, the server can be easily setup to use a PTP source as a backup to the on-board GPS and use an NTP source as a cross check. The servers can be setup to back up each other so that if one fails, the time service continues. It includes dual redundant hot-swap power supplies and 1T hard drives.

And now, with the addition of STL, you can augment GNSS signals or cut the cord altogether with an indoor solution.

Smart Reference Monitoring

The VelaSync uses smart reference monitoring to validated the fidelity of all available references. It does this by actively comparing phase offset of eac reference against the primary reference and each other. The phase error validation calculates long-term averages and standard deviations of th ephase offset between the monitored external reference and the inter system reference. The standard deviation is used to caluclate two validity thresholds; a higher and a lower one (the latter acts as a hysteresis buffer, preventing the status flip/flopping if the acutal phase error validation value varies closely around the outer threshold).


Security is a priority within the VelaSync and included as part of the standard platform. Capabilities include supporting cnetralized authentication (LDAP, RADIUS, TACACS+) journaled activity logging, secure protocol support (SSH, HTTPS), and more. Updates are generally released on a quarterly basis, but patches and fixes to major CVE's are addressed as they are discovered.
