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： A signal generating method and circuit for reducing jitters occurring in a recovered clock signal CK since even when multiple items of specific data are inserted in one cycle of generation period for an enable period, a deviation of an output cycle of the enable period can be eliminated.Accordingly, when a signal for clock recovery ED is generated, which is formed by alternately generating enable periods EN having a ratio (N/M) of N clocks' client data to M clocks' line data and disable periods D1 to D4, a phase of the disable period D2 is advanced by a phase corresponding to the disable period (such as one clock period) during the enable period with reference to phase information added to the signal for clock recovery ED when a stuff pulse in the line data is detected as indicated by the symbol m0, thereby generating the signal for clock recovery ED.
