Abstract

PURPOSE:To recover a step out dependent upon disturbance in a short time to improve reliability by re-establishing synchronization every frame of transfer data between terminal equipments. CONSTITUTION:Parallel mode data 22 of equipment M is set to parallel series converter circuit 20 from main control circuit 1, and is transferred to equipment S as series data 8 through gate 21. Following mode data, transmission data 6 is transmitted through parallel-series converter circuit 2M and gate 5M. In equipment S, bit counter 4 is always reset by synchronizing signal 19, and eight bits following synchronizing signals are used as mode data to convert transmission data 18 to series data 8 and transfer this data to equipment M at the timing of the third character from synchronizing signals. The synchronization between counters 4 of equipments M and S is re-established every one frame (three characters).
