Abstract

PURPOSE:To ensure an assured insertion of the data into the frame of the transmission line, by transmitting the false random signal to the transmission line, deciding the number of the frames on the transmission line of the loop transmission system and then informing both the number and the sequence numbers of the frames to the signal processor. CONSTITUTION:The false signal is delivered from the false random signal generating circuit PG1 via the signal produced by counting the pulses sent from the timing generating circuit TIM through the counter CT1. This false signal is shifted to the region in the frame to be transmitted to the transmission line 1. The line is sent back to the transmission device 2 again after a circulation, and the value of the region in the frame is applied to the single side of the comparator CP1. And the output of the false random signal generator PG2 is applied to the other input of the circuit CP1. Then the counter CT2 is controlled through the synchronous lead-in control part CON until a coincidence is obtained between the both signals, thus securing a perfect synchronization. And the number and the sequence number of the frames are obtained via the differential detecting circuit SUB, the frame number holding register RG and the like to be then transmitted to the data signal processor. Thus the data can be inserted into the frame assuredly.
