Abstract

A method and a system for providing information for recovering a clock frequency via a data network comprise generating a value representative of a frequency difference between a clock frequency and a reference frequency by using a digital phase-locked loop at an ingress interface of a data network, transmitting the generated value over the data network, and recovering the clock frequency at an egress interface of the data network by using the reference frequency and the transmitted value. Other systems and methods are also disclosed.
