VCL-2145, Primary Reference Clock with IEEE-1588v2 Grandmaster and NTP Server is a high precision, multi-service, cost efficient time and frequency synchronization solution which can be used to provide ITU-T, G.811 reference frequencies which are referenced to a GPS source, as well as to synchronize the time-of-day and frequency across multiple nodes of the network. The VCL-GPS Receiver has an integrated, high bandwidth NTP Server engine that is capable of handling up to 6000 NTP requests per second. Multiple IRIG-B Outputs are also provided to synchronize local clock (time-of-day) display units as well as RTUs to a central timing source with nanosecond accuracy.
VCL-2145 (VCL-2145-D) is a high-performance, GNSS (Global Navigation Satellite System) Primary Reference Clock that provides ITU-T G.811 Primary Synchronization Frequency References which are locked to a user selected GNSS (GPS-GLONAS-SBAS) Satellite source.
The VCL-2145 (VCL-2145-D) Satellite Receiver also has an integrated, high bandwidth NTP Server engine that is capable of handling up to 3000 NTP requests per second. Multiple IRIG-B Outputs are also provided to synchronize local clock (time-of-day) display units as well as RTUs to a central timing source with nanosecond accuracy.
User selectable GNSS options:
Valiant’s VCL-W-KLOX is a high precision digital clock that offers un-matched reliability, dependability and security that is not commonly found in similar competing products. The VCL-W-KLOX is a temperature hardened design with industrial grade EMI, EMC and surge protection provided on all interfaces making it suitable for installing in the harshest industrial or commercial environments that may include sub-stations, mines, defense installations, airports, railway, metro stations as well as industrial establishments.
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)”.
High precision NTP Display Clocks available in HH:MM or HH:MM:SS format. 2-inch, 4-inch and 8-inch LED Digit Size and 110~240V, 50/60Hz AC, or 24-72VDC power supply options.
VCL-2145-LC (VCL-GPS-2145), GPS Primary Reference Clock is a high precision frequency synchronization solution which may be used to provide ITU-T, G.811 Primary Reference Clocks which are referenced to a GPS source.
The VCL-2145-LC (VCL-GPS-2145), GPS Primary Reference (PRC) Clock is specifically designed for frequency synchronization of 2G, 3G, HetNet and LTE mobile telecommunications networks as well as backhaul wire-line SDH / SONET and Synchronous Ethernet networks. It may be also used by Railways, Airports (and air-traffic control), Power generation and distribution companies and other Utility companies who not only require highly precise G.811 frequency synchronization locked to a GPS Reference
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.
