VCL-3048, NTP Time Server
The VCL-3048 NTP Time Server is designed to provide NTP 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 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. VCL-3048 locks to a GPS / GNSS reference to provide an NTP time on a 10/100 BaseT Ethernet Port which can be used to serve various types of assets in the network.
