The VCL-GPS Receiver is specifically designed for the synchronization of 2G, 3G and LTE mobile telecommunications networks as well as backhaul wireline SDH / SONET and Synchronous Ethernet networks. It may be also used by Railways, Airports (including air-traffic control), power generation /distribution companies and other utility companies who not only require a highly precise time-of-day and frequency synchronization locked to a GPS Reference but who also need to distribute highly precise time-of-day and frequency synchronization across all nodes of their networks.

The equipment conforms to and provides a G.811 / Stratum 1 quality synchronization (GPS locked) reference while providing multiple time (IRIG-B) and frequency outputs that are usually required by the users of such equipment.

The VCL-GPS, GPS Receiver is equipped with an integrated GPS receiver and a highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability holdover quality typical of an SSU in the eventuality of the GPS signal or its antenna failure.

The Grandmaster Clocks supports IEEE-1588 PTP Version 2 and delivers nanosecond time and frequency synchronization for customer network environment. VCL Grandmaster Clocks not only provides a highly accurate source of synchronization for PTP networks and also provide ToD (Time of Day) and Frequency Synchronization. Supported options include IRIG-B, 1 PPS, NMEA, 1/5/10MHz, 2.048MHz, 2.048Mbits clock outputs. OCXO and Rubidium Holdover Clock options are available.

VCL PTP IEEE-1588v2 Slave Clock devices simplify the migration towards PTP IEEE 1588v2 by providing a wide range of legacy time synchronization outputs. The PTP IEEE-1588v2 Slave Clocks are synchronized to a PTP Grandmaster and can be used as a timing synchronization source for equipment that requires IRIG, PPS, 1/5/10MHz or E1 telecom carrier signals.
