GPS/GNSS NTP Server Primary Reference Clock
with optional IEEE-1588v2 PTP Grandmaster
GP-1100, PTP IEEE-1588v2 Grandmaster with an integrated NTP server is designed to provide PTP, NTP and ITU-T G.811 Primary Reference Clock that is locked to a GPS / GNSS Reference to provide time synchronization to private networks such as Railways and Metro (ticketing and platform) networks, Airports and Air-Traffic Control facilities, Electric Sub-Stations, Power Distribution and Transmission companies, Oil and Gas Utilities, ISPs and Cable TV networks as well as to Campus networks that are required to maintain complete isolation from public networks for security reasons. It may be also used by 2G, 3G and LTE service providers which provide a time of day reference to their customers over their wireless networks.
GP-1100 locks to a GPS / GNSS reference to provide an NTP time reference on up to 4+1, 10/100BaseT Ethernet Ports which can be segregated to serve separate classes of assets in the network.
The GP-1100 is equipped with a highly accurate, low-noise OCXO to provide a high stability, ITU-T G.812, Type II, III compliant holdover clock with better than 12µs accuracy over a 24 hour (5 milliseconds per year) period in the event of unavailability of the GPS / GNSS signal, or GPS / GNSS antenna failure, or a temporary loss of reception in a totally isolated network without any external reference.
GP-1100 establishes a highly accurate phase-synchronized frequency and time base by synchronizing to the GPS / GNSS satellites’ atomic clocks to distribute synchronized time over packet based networks including Ethernet, Carrier Ethernet, IP and IP/MPLS Networks. The GP-1100 provides a wide range of GPS / GNSS referenced frequency and time sources that include 2.048MHz, 10MHz, 1PPS frequency as well as an NMEA and NTPv4 time reference. Features such as maintaining a distinctly separate IP address for system management and control, password based access, SSH as well as MD5 and SHA1 authentication for NTP requests ensures operational reliability and security. Additional features include remote login and remote firmware upgrade capabilities. GP-1100 includes complete SNMP monitoring as well as support for enterprise directory services for user authentication, internal and external logging and monitoring of alarm and error messages through Syslog and e-mail alert ensures a high level of system manageability. Other features include DHCP for installation convenience and support concurrent IPv4/IPv6 support for future network upgrades.
