GMR1000 - Multi-Functional Master Clocks
The GMR1000 is a compact time and frequency generator/server that can reference a variety of timing sources and provide a range of outputs to meet customer needs. The base model includes both NTP client and server functionality compatible within IPv4/IPv6 networks and offering Secure-Socket-Host (SSH) encrpyption for secure communications. Properly configured and using standard NTP polling rates, the device can support and synchronize hundreds of thousands of NTP clients.
