The NTP100-OSC NTP is a stand-alone time server from Masterclock that synchronises to a TCXO (temperature-compensated internal oscillator) and sends NTP reference signals to NTP devices via Ethernet, maintaining an accuracy of ± 1min/year or < 165ms per day.
An optional OCXO increases stability to ± 250ms/year.

Assignable network configuration
Configuration via Telnet/SSH or included WinDiscovery
IPv4/IPv6 compatible
MD5 authentication
Time stamp precision/resolution of 5-10ms
Specifications
