The VCL-2145-D incorporates up to dual (1+1 redundant) GPS / GNSS receiver engines and dual (1+1 redundant) power supply options for added reliability which are always locked to a user selected satellite (GPS / GNSS) reference to provide multiple G.811 / Stratum 1 quality frequency and time-of-day (PTP, NTP and IRIG-B) outputs. The VCL-2145-D is also equipped highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability holdover clock that is typical of a Network SSU in the event of the GPS / GNSS signal, or its antenna failure.
