GP-4100 is a high-performance, high-reliability GPS Primary Reference Clock and IEEE-1588v2 PTP Grandmaster that provides ITU-T G.811 Primary Synchronization Frequency References which are locked to a user selected Satellite source. The GP-4100 Satellite Receiver also has an integrated, high bandwidth NTP Server engine that is capable of handling up to 5000 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 GP-4100, 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 but who also need to provide an accurate time-of-day reference in their networks.
The GP-4100 incorporates up to dual (1+1 redundant) GPS receiver engines and dual (1+1 redundant) power supply options for added reliability which are always locked to a user selected satellite (GPS) reference to provide multiple G.811 / Stratum 1 quality frequency and time-of-day (PTP, NTP and IRIG-B) outputs. The GP-4100 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.
