NTP Network Time Server

GlobalTime ® NTP Network Time Server supplies accurate time for all computers and time keeping devices on the network. By placing a time server on the local network, (S)NTP time packets are provided without requiring systems to go to the Internet to get a Stratum 1 time synchronization. The system uses an active GPS antenna to maintain the current time as broadcast by GPS satellites.

Features

• Stratum 1 operation via GPS/ BeiDou/ GLONASS satellites

One/ two/ four standard GbE ports, all with patented NTP hardware timestamping

• Security-hardened NTP Reflector™ with firewall protection

• Web-based management with high-security cipher suite

• Exceptional time accuracy to UTC

• Extended environmental specifications

• IPv4 on all ports

• Rubidium atomic clock or OCXO oscillator upgrades

• Single power supply or dual power supply option

• Can be set as a slave time server to synchronize with host time server

• One 10M/ 100M/ 1000M adaptive network interface

• NTP Reflector option: 20000 NTP client mode three requests per second

• TOD/1PPS/10MHz out

• MTBF: 90000 Hours

 

Applications

• Synchronizes hundreds of thousands of NTP clients

• Security-hardened for peace-of-mind time service operations

• Multiple GbE NTP ports for easy network configuration and adaptation

• Best-in-class time accuracy for improved log file timestamp precision and usability

• Very reliable and easy-to-use network time appliance for modern networks and business operations
