Abstract: The invention provides a method and system for synchronizing a transmitter and a receiver wherein the transmitter generates phase difference information indicating a phase difference between an internal and an external clock, the phase difference information is transmitted to the receiver, and the receiver generates a clock signal dependent on the transmitted phase difference information.

Abstract: A synchronous transmission system including a circuit arrangement for determining the data bytes of a signal to be received or to be transmitted. The circuit arrangement includes a control circuit (2, 14) which includes at least a counter (11, 19) for marking the pointer bytes of each high bit rate transport unit that can occur and which circuit arrangement includes at least a counter (6, 17) for marking with a count the data bytes of each high bit rate transport unit that can occur. The control circuit (2, 14) further includes for each group of low bit rate transport units that can occur in each maximum bit rate transport unit that can occur at least a position counter (6, 17), which counter is provided for marking with a count the data bytes in a low bit rate transport unit of the group. The control circuit (2, 14) is additionally provided at least for identifying the payload bytes and the pointer bytes on the basis of the counts and the information about the transport units of the signal.
