VCL-2145, Primary Reference Clock with NTP Server
VCL-2145 Primary Reference Clock and NTP Server (IPv4 and IPv6), provides IRIG-B, 1PPS, NMEA, 1/5/10MHz, 2.048MHz, 2.048Mbits with SSM, 1.544Mbits GPS referenced clock outputs. OCXO and Rubidium Holdover Clock options available.
VCL-2145, Primary Reference Clock with 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-2145 Receiver has an integrated, high bandwidth NTP Server engine that is capable of handling up to 8900 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.
The VCL-2145, Primary Reference (PRC) Clock is specifically designed for the 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 (including air-traffic control), Power generation and distribution companies and other Utility companies who not only require a highly precise time-of-day and G.811 frequency synchronization locked to a GPS Reference but who also need to distribute highly precise time-of-day and frequency synchronization across all nodes of their networks.
The VCL-2145 is always locked to a GPS reference to provide multiple G.811 / Stratum 1 quality frequency and time-of-day (IRIG-B and NTP) outputs. The VCL-2145 is also equipped highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability holdover clock that is typical of a Network SSU in the event of the GPS signal or its antenna failure.
