The ITU-T is a group of experts who create rules for telecommunications technologies. They have recently agreed on a new rule called "Recommendation G.8273.4". This rule explains how to use a technology called Partial Timing Support (PTS) on networks that use IEEE 1588 PTP. This technology helps keep different parts of a network synchronized with each other, and the new rule explains how to measure how well it's working. The Technical Briefs below can give you more information about how network timing is changing and improving.
This document provides an overview of what PTS is and how it is used in the network. It also describes the clocks themselves and how they work. PTS: Testing G.8.273.4 (below) is a companion document and describes the approach required to test these clocks in the lab.
Top 3 things you will learn:
- Level of PTP support provided by the network.
- Use Cases for PTS
- Relevant Standards for PTS
This document provides a summary of how to test these clocks in the laboratory.
- Partial Timing Support Clocks
- Testing APTS Clocks

The Paragon-neo offers incredibly precise timing measurements in the range of a billionth of a second, even when dealing with data speeds as high as 100 Gigabits per second. It's designed to assess devices that combine different technologies, doing so at the same time and providing information about the accuracy of their timing, synchronization, and how well they maintain a stable pace of data transmission.
Furthermore, the Paragon-neo excels in its ability to measure the timing of outgoing data packets, the stability of internal clocks, and the consistency of synchronization. This accuracy and reliability in testing are unmatched.
