thiết bị đồng bộ thời gian hãng Meinberg model LANTIME M300/ GPS NTP Server in 1U Case for Server Rackmount
The Meinberg LANTIME M300 time server provides accurate time to networks of any size. It synchronizes all NTP- or SNTP-compatible systems. The M300 time server uses as a reference time source either any compatible external or built-in Meinberg reference clock (Stratum 1 mode) or up to 7 NTP servers (Stratum 2 mode).
