In Packet based timing, the prediction, monitoring and management of Packet Delay Variation is complex, challenging, potentially costly and still open to random 'network noise' events.
Placing a predictable, stable and cost effective local clock at the client node can greatly improve the odds in dealing with network noise – increased client robustness allows a timing to be deployed across larger and less managed networks, reducing the overall cost of a timing solution.
Vectron matches the stability characteristics of its oscillators with the requirements of 1588 client clocks – this is done by design, but also through a system level verification of the oscillators' suitability in the target application. Choosing oscillators for 1588 applications is in many ways similar to selecting devices to support SONET/SDH 'stratum' level applications. However the role of PDV and any corresponding packet filtering used in a Packet Equipment Clock (PEC) needs to be considered also, since the system loop filter bandwidth is not necessarily pre–defined in the same way as SONET/SDH.
