<p>The present invention refers to a method and an apparatus for synchronizing operation at a node of a communication network. According to the invention, a node is arranged to receive two or more input frame synchronization signals and to transmit an output frame synchronization signal, the output frame synchronization signal being associated with a predefined one of said input frame synchronization signals. One of the input frame synchronization signals are selected to define a node common frame synchronization signal. The output frame synchronization signal is generated using the node common frame synchronization signal as reference for synchronization. A phase relationship between the output frame synchronization signal and the input frame synchronization signal that is associated therewith is determined and is adjusted by the step of adjusting a phase relationship between the output frame synchronization signal and the node common synchronization signal when generating the output frame synchronization signal.</p> |
