Abstract

PURPOSE:To prevent the transmission of vacant telegraphic message and duplicated transmission, by preventing a plurality of callout stations from transmitting telegraphic messages at the same time, through the return of inherent response code at every callout station. CONSTITUTION:Party station numbers X1, X2, X3 is transmitted into a callout block (1) together with the number of ADR2 station itself indicating a callout station (2), and a called out station interprets the received block (1) to form the code (2) inherent to the callout station and this code is returned to the callout station as the response code. The transmission/return is repeated twice and after the number ADR2 is received twice surely, data blocks (5) and (7) are sequentially transmitted.
