TELECOMMUNICATIONS NETWORK

摘要

A method for generation of a clock (22) synchronized with time references derived from input signals (12) in an apparatus (10) of a telecommunications network comprising an input part (11) receiving the input signals and a part (13) for treatment of said input signals is described. In the input part (11) the method comprises the steps of deriving the time reference signals from the input signals, reading a 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 (13) the method comprises the steps of receiving the frame, extracting said pointer, generating said time reference clock (22) and synchronizing it with the position in the frame indicated by the pointer. An apparatus applying this method is also proposed.
