摘要： The present invention provides a signal block sequence processing method. According to the method, signal block headers (Bch, Bdh) are deleted from each sequence of signal blocks (B) each composed of the signal block header indicating whether a signal block payload is a control block payload (Bc′) containing a control code is contained or a data block payload (Bd′) containing data is contained. The resultant signal blocks are formed into one group (G). Each control block payload in the group is provided with position determination information indicating the position of the control block payload in the group. The signal block payloads are rearranged in accordance with a signal block payload rearrangement rule. The rearranged signal block payloads are contained in a super-block payload (Sc), to which a super-block header (Shc) indicative of containment of control block payloads is added. The resultant super-block (S) is output.

摘要： A digital transmission system includes at least a client device and a transmission device, and rate-adjusts the client signal transmitted from the client device to the transmission device before accommodating/multiplexing the signal in a frame. The transmission device includes a rate adjusting unit and a frame processing unit. The rate adjusting unit encapsulates the client signal by using a predetermined frame structure, inserts an idle pattern if necessary, and performs rate adjustment into the bit rate which can be contained in the frame. The frame processing unit accommodates/multiplexes the signal after the rate adjustment. The digital transmission system inserts a bit string of the client signal directly in a payload area of the digital frame, or accommodates and multiplexes it. Alternatively, a specific pattern is accommodated in the payload area, or accommodated and multiplexed after performing a reversible digital signal processing.

摘要： The present invention proposes a method whereby during a specified/specifiable observation period (Ttotal) , the polarization states of optical transmission system and/or the optical signals transmitted by the optical transmission system are changed by applying a targeted intervention in at least one position of the transmission line, and at a second position which is interposed at least one place downstream from the first position of the optical transmission line, a specified/specifiable signal characteristic (BER) is qualitatively measured and checked for adherence to a specified/specifiable threshold condition (BERth) and the PMD-induced outage probability of the optical transmission system is calculated on the basis of the ratio between the length of that share of the time (Tout), during which the measured signal characteristic fails to meet the threshold condition (BERth), to the length of the observation period (Ttotal).
