Middle range Time Server with built-in high stability OCXO crystal oscillator

High precision time synchronization is possible even if the GPS antenna is installed indoors due to the built-in high performance GPS receiver

  • Oscillator stability: +/-10ms/day
  • Time source: GPS

Features of TS-2550

Features 1  Highly Accurate Time Synchronization

GPS time source enabled high precision time synchronization in plus/minus 1ms accuracy. Stable time can be maintained even if GPS signal is lost using its built-in high precision crystal oscillator (OCXO) in plus minus 10ms/day accuracy.

Features 2  Completely Independent 4 LAN ports

4 LAN ports enable multiple network connections without router, etc.

Features 3  User Friendly Operation 

  • Easy setting and maintenance with intuitive GUI (web-based)
  • Alert notification of status change by various ways via SNMP,Syslog and SMTP

Features 4  Unique Function

  • The time monitoring function which monitor the time sync status of the clients
  • Two leap second adjustment methods with gradually mode and immediate mode

Features 5 High Performance NTP Processing

Up to 8,000 NTP requests per second can be handled which is more than 10 times of TS-2210 in processing capability and gives you extra assurance for large scale system.
