ABSTRACT:
A method for generation of a clock synchronized with time reference signals derived from input signals in an apparatus of a telecommunications network comprising an input part receiving the input signals and a treatment part for treatment of the input signals. In the input part the method comprises the steps of deriving the time reference signals from the input signals, reading an edge of the reference signals, establishing the position of this edge relative to the internal data frame, inserting in the frame heading a pointer representing the established position of the edge relative to the frame and sending the frame to the treatment part. In the treatment part the method comprises the steps of receiving the frame, extracting the pointer, generating the time reference clock and synchronizing it with the position in the frame indicated by the pointer. An apparatus applying this method is also proposed.
