<p>PURPOSE:To realize the frame synchronizing equipment having a strong synchronization protection characteristic and eliminating mis-synchronization quickly with high reliability. CONSTITUTION:Since the equipment is provided with a pattern detection means 10 collating a pattern of a reception signal and a specific frame synchronization pattern whose dissidence discrimination threshold level is varied, and a control code detection means 11 detecting a voice suppression bit included in the reception signal and outputting a signal to select the dissidence discrimination threshold level for the pattern detection means 10 depending on the content of the bit, the frame synchronization equipment having strong synchronization protection characteristic and releasing quickly mis-synchronization is realized.</p> |
