摘要： The invention relates to a transmission system for transmitting and detecting the beginning of the frame of a frame synchronized signal, which comprises a first and a second detection circuit (1, 2) and an evaluation circuit (3). The first detection circuit (1) is provided for setting a first detection signal (D1) to a first state upon detection of a first bit sequence located at the beginning of the frame of the signal, and the second detection circuit (2) for setting a second detection signal (D2) to a first state upon detection of a second bit sequence located at a specific frame position of the signal. The evaluation circuit (3) comprises a frame counter (10) which is provided at least during the detection of the beginning of the frame, for resetting the first detection signal (D1) to an initial value after the first state has occurred, and a combining circuit (15) for forming a frame state signal (R) which has a first state only when the first state of the first detection signal (D1) occurs during the initial value, and the first state of the second detection signal (D2) occurs during a specific frame value of the frame counter (10).
