TimeProvider 4100 Precise Timing Gateway Clock

TimeProvider 4100 Timing Grandmaster, the precise timing grandmaster with gateway clock and fastest high-performance boundary clock, to enhance 5G mobile network phase protection.

New software release 2.1 builds on earlier versions by adding key software enhancements providing a virtual Primary Reference Time Clock (vPRTC) providing the ability to design a redundant precise time distribution architecture for phase protection over an optical network.


All robust networks are designed to mitigate the impact of losing a synchronisation feed, but what happens when a feed deteriorates and remains undetected? When is poor sync worse than no sync?

A network operator experienced just this. Due to an unpredictable chain of events, a master clock was left to output a corrupted signal which remained undetected by downstream equipment. The situation resulted in loss of revenue and dissatisfied customers but also impacted emergency services. The master clock issue was resolved soon after it was detected, but could the supervisors of the downstream equipment benefited from an early indication of the poor sync quality?


The loss of synchronisation quality would have been detected by SyncWatch, the 24/365 sync measuring and monitoring platform from Chronos.

SyncWatch continuously monitors a wide range of physical layer and packet synchronisation signals and when deployed correctly can alert users to current or impending issues. Using the upstream reporting methods sync quality alarms and data can be integrated into other management systems.

Reporting real time sync performance data enables the operations team to see network synchronisation problems promptly and be able to react quickly to assure continuous delivery of service quality.
