The Cern C-2000 from Brilliant Telecommunications, Inc., is a 19-inch rack-mountable Primary Reference Source (PRS) and Primary Reference Clock (PRC) that provides superior timestamping accuracy and redundant configurability.

The C-2000 accepts a GPS signal from a variety of manufacturers’ antennas and provides
antenna power via an attached RF cable. The server is also capable of accepting a signal from timing sources such as Galileo and GLONASS antennas, or via Network Time Protocol (NTP) from a network peer.

The C-2000 uses highly accurate NTP and Precision Timing Protocol (PTP) technology. With timestamping performed in the hardware, the C-2000 provides wirespeed NTP/PTP with unparalleled accuracy while decreasing vulnerability to Denial of Service (DoS) attacks. In the event that a direct connection with the GPS is interrupted—and without the use of a local Rubidium oscillator—the C-2000 maintains Stratum 2
synchronization. This accuracy is preserved because the C-2000 will engage with other C-2000s in the same network to retrieve the necessary information.

Because of its integrated platform, the C-2000 replaces previous generations’ equipment at a lower total cost of ownership. The network timing distribution capabilities of the C-2000 reduce the need for expensive Rubidium or Cesium timing elements in the network; however, a Rubidium internal oscillator option is available for standalone or central office deployment.
