GPS NTP Time Server For Network Time Synchronization
GPS NTP Server : SYNTIME
GPS NTP Time Server (SYNTIME) for Network Time Synchronization is a highly accurate time server. It generates time protocols to synchronize NTP/SNTP clients (Simple Network Time Protocol)/PTP clients (Precision time protocol IEEE 1588) over the network and operates at a speed of 10/100/1000Mbps. The NTP server accepts the time and frequency signals from sources like GPS or GLONASS. It achieves nanosecond accuracy and the system clock operates at stratum 1 when synchronized with time sources. It is a sleek, rack-mountable unit that synchronizes and maintains equipment/device time and avoiding any time drifts due to local RTCs. NTP output from time server supports unicast, broadcast, and multicast methods based on selection and behaves like a reference clock for the network. Apart from time synchronization protocols, it supports MD5 (Security key), SNMP, SSH, HTTP (Configuration), TELNET, FTP, and SYSLOG. IP address of the LAN ports can be field configurable.
NTP server is compatible with the IPv4 network and PTP server compatible with both IPv4/IPv6 networks. The time server complies with Leap second correction and DST settings. In addition, GPS NTP Time server is available with a variety of additional output ports: IRIG B Time Code, Fiber Optic Pulse, RS232, RS485, PFC, and Fiber Optic Ethernet outputs. It has the ability to send alert notifications via SNMP Traps. Above all, it’s a cost-effective solution for Stratum-1 time synchronization across your network.
GPS NTP Time server is designed to provide time synchronization to networks such as Electric Sub-Stations, Power Generation and Distribution, Transmission companies, Oil and Gas Utilities, Railways and Metro networks, Airports and Air-Traffic Control facilities, Internet Service Providers (ISPs), and Cable TV networks as well as Campus networks that are required to maintain complete isolation from public networks for security reasons.
