Title: Multiplex transmission system
Inventor: KONDOU ISAO
IPC: H04L7/08
Filed: 1978-05-17
Abstract: PURPOSE: To realize multiplex transmission, hard to become out of synchronism, which makes it possible to distinguish definitely the synchronizing signal of any input data.  
     CONSTITUTION: One frame is composed of four words and each word is of ten- bit constitution with two out of ten assigned for a synchronous pattern. When a series signal of the above frame constitution arrives, a clock component is extracted from the signal by clock extraction circuit 41 so as to obtain a clock signal which synchronizes with the transmission side. By this clock signal, word generating circuit 42 forms exactly the same word-synchronous pattern as the transmission side and word-synchronous pattern comparator circuit 43 compares this word synchronous pattern with that in the received series signal; when the both disagree, shift- pulse generating circuit 44 is triggered to generate a shift pulse, which is supplied to a rotary switch at the rception side, thereby making a shift.
