VCL-2103:High Performance NTP Sub-Master Clock
VCL-2103 – NTP Sub-Master Clock

Valiant’s VCL-2103, SUB-MASTER CLOCK is a high performance, “intermediate” time synchronization source which may be referenced to multiple Primary GPS Reference (Master) Clock(s) using NTP protocol to provide "Time-of-Day" synchronization to client-side NTP/SNTP Slave devices in the network. Applications of Valiant’s NTP Sub-Master Clock include all such installations where network segregation is considered to be essential to isolate sections of the network that are considered to be less secure that require added cyber-security.

Valiant’s NTP Sub-Master Clock emulates the “CLOCK-IN-THE-MIDDLE” which installs between a secure (client) network(s) and an un-secured (public) network to allow the client-side terminals to securely synchronize to the public NTP servers with comprehensive network security. The NTP Sub-Master Clock incorporates a firewall that assistes in securing the “Client Network” from hostile attacks and intrusions that can originate from an un-secured, or less-secure sections of the network. The VCL-2103 Sub-Master Clock mediates between the Primary GPS Reference (Master) Clocks and the Slave NTP/ SNTP devices, such as Time-of-Day Display Clocks in a LAN, to effectively isolate the GPS Primary Reference Clock Source from the NTP/SNTP Slave devices and provide NTP/SNTP time-of-day synchronization with better than 0.5 millisecond accuracy.

The VCL-W-KLOX can be installed in a network to synchronize with multiple “Reference (Master) Clocks” to provide 1+1 or n+1 source redundancy in a NTP/SNTP time synchronization network. The VCL-W-KLOX is a highly accurate time display unit that is equipped with an internal TCXO which provides better than 0.1 second / day hold-over accuracy in the event of loss synchronization with its “Reference Time Source(s)”.
