发明名称 Synchronous transmission system for carrying multiplexed signals
摘要 The invention relates to a transmission system comprising a synchronizer for forming a multiplex signal, comprising at least a device for conveying the multiplex signal, and a desynchronizer. The desynchronizer comprises at least a buffer store for buffering transport unit data contained in the signal, a write address generator for controlling the writing of the data in the buffer store, a control arrangement for forming a control signal for the write address generator from the signal, a read address generator for controlling the reading of the data from the buffer store, a difference circuit for forming difference values between the addresses of write and read address generators and a generating circuit for generating from the difference values a read clock signal applied to the read address generator. The control arrangement is further provided for detecting the offset of at least one transport unit in the signal and for informing a correction circuit of the detected offset, which correction circuit is used for forming the phase difference between a lower-order transport unit and a higher-order transport unit. A combiner circuit is provided for combining a correction value which is the result of the subtraction of the two phase differences and a difference value from the difference circuit.
