    摘要: A non-interruptive protection switching device which performs protection switching in a more efficient and robust way. The device has a working-channel signal storage unit to store data signals received through a working channel. Multiframe synchronization timings are detected by a working-channel multiframe synchronization controller, which provides a working-channel multiframe sync detection pulse signal when the main signals are in a normal condition and stops it when the channel is disrupted. A working-channel write controller controls every write access to the working-channel signal storage unit, generating a write pulse signal therefor. The working-channel write controller also produces working-channel write phase data by identifying a phase difference of the detected multiframe synchronization timing with respect to a reference phase signal. The generation of this write pulse signal is based on the multiframe sync detection pulse signal when the working-channel multiframe sync detection pulse signal is available, or on a free-running timebase when it is stopped. The stored data in the working- and protection-channel signal storage units are read out simultaneously, under the control of a read controller which produces read pulses from the write phase data.
