The accuracy of a watch depends on the application. Anyone who wants to catch a train has to have an eye on the minutes. In competitive sport, a hundredth of a second can be decisive and a packaging machine may need microsecond accuracy.

This paper reviews techniques of frequency and phase distribution by means of packet networks that require new synchronization architectures. PTP is the key technology for those applications requiring an accuracy of micrfoseconds.

Zeus helps to design, install and maintain all the communication networks of the Power Utilities including the new ones based on IEC 61850 standards sucha as PTP or GOOSE, and legacy protocols as such as IRIG-B or C37.94.

xGenius is a tester to install and maintain Telecom and Utility networks with new and legacy interfaces including GbE up to 10G, PTP, NTP, SyncE, ToD, IRIG-B, T1 / E1, C37.94, RS-232, G703, and it also captures protocols like GOOSE, SV or MMS.
