VCL-2145 G.811 PRC SSU and NTP PTP time server

VCL-2145 is an NTP time server and PTP Grand-Master, and a G.811 PRC / SSU synchronisation clock with GPS input. It embeds a high accuracy OCXO or Rubidium oscillator with G.812 hold-over performance

VCL-2145 PRC SSU et serveur NTP PTP

VCL-2145 provides synchronisation to many applications in public transportation for ticketing and signaling requirements, to utility distribution, to airport management and airflight control, to Internet and broadcast services, to landline telecom and LTE / 5G mobile networks, and banking transactions. VCL-2145 is also a PRC reference clock and a SSU synchronization distribution unit for SONET, SDH, PDH TDM networks.

VCL-2145 brings many benefits to those mission critical networks:
