Overview

Valiant’s PTP IEEE-1588v2 (Precision Time Protocol) Grandmaster is a very versatile product that is designed to be used in both contemporary and legacy synchronization applications. Valiant’s PTP IEEE-1588v2 (Precision Time Protocol) Grandmaster includes a highly accurate and powerful PTP Grandmaster engine that can be used in both telecom and power networks. In addition to supporting PTP telecom and PTP power profiles, it also provides ITU-T G.811 compliant, 2.048Mbits (E1), 2.048MHz, 1.544Mbits (T1) primary reference clocks that can be used to synchronize legacy SDH and SONET networks. Furthermore, its integrated NTP Server may be used to provide time-of-day synchronization to NTP slave terminals / equipment that require NTP / SNTP mode of synchronization.

The equipment also provides a Stratum 1 quality (GPS locked) 10MHz synchronization reference with multiple time (1PPS, IRIG-B) and frequency outputs that are usually required for synchronizing 2G, 3G, 4G, 5G / LTE mobile telecommunications networks, Micro Cell sites. 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 / GNSS Reference but who also need to distribute highly precise time-of-day and frequency synchronization across all nodes of their networks.

The VCL-GPS / GNSS Receiver is equipped with an integrated GPS / GNSS 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. Both OCXO and Rubidium Holdover Clock options are available.
