Abstract
A frame synchronism processing apparatus including a first detecting unit for detecting the synchronism of a subframe, a second detecting unit for detecting the synchronism of a multiframe, and a synchronism detection retrying control unit for forcibly bringing the first detecting unit and the second detecting unit into a synchronism detection retrying mode if the second detecting unit has failed to detect the synchronism of the multiframe. Assuring that a false synchronous state is brought about on the subframe synchronism with the result that the detection of the synchronism of the multiframe has been failed, the detection of synchronism of the subframes and the detection of synchronism of the multiframe are retried, thus avoiding a deadlock of frame synchronism process due to the possible false synchronous state and hence improving the reliability in synchronism process.
