<p>PURPOSE:To ensure an assured matching of synchronism for each channel, by setting forcibly a counter that counts the receiving clocks at a prescribed level when a synchronizing counter reaches the prescribed value. CONSTITUTION:The same pattern for matching of synchronism is inserted through an FF113 and transmitted to plural channels of each period. Each node device detects the received synchronism matching pattern, and the number of receiving clocks produced from the receiving information obtained after the detection of said pattern is counted by a synchronizing counter 106. Then the signal is produced after detecting through a coincidence circuit 102 that all synchronism matching patterns are received continuously. When the counter 106 reaches the prescribed value, the counter 114 counting the receiving clocks is forcibly set at a certain level.</p> |
