VCL-2156 PTP-NTP Server

The VCL-2156 is a high-precision GNSS-based timing server that provides PTP Grandmaster (IEEE 1588v2) and Stratum-1 NTP synchronization for power utilities, telecom networks, and large industrial systems. With exceptionally low time error and hardware timestamping, it delivers sub-microsecond accuracy required by digital substations, PMU systems, and 5G backhaul. The device supports GPS/GLONASS/BeiDou and provides redundant timing outputs including 1PPS, 10 MHz, IRIG-B, ToD, NTP, and multiple PTP profiles (G.8275.1/2). Designed for reliability, the VCL-2156 includes holdover OCXO/Rubidium options, dual power supply, secure management, and compliance with IEC 61850 and NERC-CIP guidelines.
