Abstract

PURPOSE:To eliminate an insertion of the address information with every transmission slot and at the same time ensure a simple control or the like for a simultaneous request to a station in case the data is transmitted among the stations connected by a transmission cable in a time-division multiplex system, by fixing the station that can have a transmission to the slot. CONSTITUTION:A time slot is allotted to each of stations 1-m in a fixed way, and the address signal A is provided at the beginning part of a data. At the reception part, the signal is delayed by a shift register to perform a decision of address. Thus the address corresponding to the relevant station is detected, and the slot number is stored. After this, the slot data of the slot number is received continuously until the end of the reception data. On the other hand, a set or reset control is given to the flag bit in the slot at the reception station. Thus the propriety is controlled for the slot transmission of the trasmission side by sending the flag bit showing a slot reception back to the transmission station.
