A local accurate time reference will help keep your computer networks safe*. A local time reference allows you to easily synchronise all your clock displays, networks and other equipment from inside your firewall. These Masterclock servers generate accurate time, and provide reference signals in most common formats and protocols. They can be referenced to external time sources, with precision path delay adjustments, should you need a traceable source of world time. The different products in our range allow you to balance your need for accuracy, stability, signal types together with your available budget, and space.
A modular grandmaster master clock able to generate all major time signals and protocols. It can be free running or referenced from one or more signals. 1RU high and using the full rack width, gives it plenty of space for all the additional modules needed to achieve seriously accurate, precision time keeping. Options include higher stability oscillators - including an atomic clock for very accurate holdover and free running uses, multiple satellite (GPS / GLONAS / Galileo) for traceable world time references, and NTP, PTP, LTC, PPS (pulse per second) input references. The GMR5000 can support both optical and copper based networking with dual network connections when extra resilence is needed. Click here for GMR5000 data sheet, and here for a GMR5000 quotation.

* One of the easiest and most cost effective ways to enhance your overall computer network security is to use a locally generated NTP or PTP time reference, located inside your firewall. This allows you to close all the various 'high risk' ports commonly used for SNTP, NTP and PTP - which are also very popular ports for internet attackers to target. An accurate network time reference means any log file time stamps from various servers across your network will all be synchronous, allowing you to better find out what happened. With no annual license fees the cost of a local time reference will quickly pay for itself.
