FRAME DETECTION PROTECTION CIRCUIT

摘要: PURPOSE:To reduce the probability of out frame synchronism due to an error caused in a transmission line by providing 1st and 2nd algorithms as multi-point monitor algorithm selecting either when is detected for prescribed number times from synchronization state. CONSTITUTION:A bit arranged separately at each interval length x-bit configuration multi-frame. The monitored 8 points (200-207) S0 S7. When takes place, restored initial stage S0(200). S1, then higher are sequentially advanced. final point S7 reached, detection signal sent (208) process S4 repeated.
