VCL-2156, NTP Server with IEEE-1588v2 PTP Grandmaster Option
The VCL-2156 NTP SERVER is a high bandwidth NTP performance solution that is designed to provide a precise time reference (< 100ns Accuracy) when locked to a GPS (GNSS) Reference. The NTP Server provides multiple NTP Ports (4 x Independent 10/100 Mbit/s, RJ-45 Ethernet interfaces) and also provides IRIG-B Un-Modulated (BNC) and 1 x IRIG-B Modulated (RJ45) options. Applications include 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 a 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.
The VCL-2156 NTP SERVER with IEEE-1588v2 PTP Grandmaster (optional) is designed to provide a precise time GPS (GNSS) reference to provide time synchronization to private networks used by 2G, 3G and LTE service providers which provide a time of day reference to their customers over their wireless networks. Applications include 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 a complete isolation from public networks for security reasons.
The VCL-2156 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.
