NTS 02-G

NTS 02-G

The NTS 02-G is a high precision, three-port GNSS (GPS/GLONASS) referenced Network Time Protocol (NTP) and Precision Time Protocol (PTP) grandmaster or boundary clock. Compliant to the IEEE® 1588v2-2008 protocol, NTS 02-G provides secure, accurate and reliable time synchronization to digital substation networks. Each port is independently addressable and logically isolated to connect multiple networks to the same clock without compromising the network security. The addition of multi-level password protection, user access rights, SNMPv3 and built-in NTP amplification attack immunity makes the NTS 02-G a versatile synchronization solution for a range of critical network applications.
