NTS 4000

NTS-4000 delivers precise time directly into LAN using Network Time Protocol (NTP). Referential UTC time is drawn from GPS & Glonass simultaneously (product is Galileo/Beidou ready). Multiple external sources can be used simultaneously to produce weighted averaged output time. In case of losing SAT signals, the NTS-4000 disciplines itself from internal high performance OCXO oscillator. It can then operate autonomously (free run mode) for many weeks. For IT safety reasons synchronization is performed by time slewing technology to minimalize risk of manipulations on time continuum and chronology. NTS-3000 is ideal to provide common notion of precise time reference for any size IT. Elproma servers are perfect for banking, stock trading, e-commerce, billing systems, multi-server IT, and it can support electronic certification (e-signatures). This product is suitable for finacial, power distribution and telecom IT. Elproma servers are designed to operate 24/7, and therefore they use only passive cooling (no fans). NTS-4000  includes all NTS-3000 functionality, plus extra includes a various of extra synchronization standards, incl. IRIG-B, IBM Sysplex, NMEA GPS in/out emulation, GSM/PSTN/dial-up modem option*, PTP Grand Master or PTP Slave option etc.
