Abstract

A method of synchronising a local oscillator signal with a main oscillator signal in a network, wherein the local oscillator signal has a phase shift relative to and upon appearance of the main oscillator signal, which phase shift is being used as an at least initially fixed reference phase shift between the thus synchronised local oscillator signal and the main oscillator signal. Synchronisation accompanied by sudden phase jumps is thus avoided.
