Abstract

PURPOSE:To simplify the system constitution and facilitate an easy control for plural end offices, by connecting the system to plural terminal offices via a pair of transmission lines and performing the transmission and reception alternately while giving the time-division scan to these terminal offices to collect the data. CONSTITUTION:A control station 1 sets the transmission bit at ''1'' (ON) and designates the address of the 1st end office 3a to transmit the transmitting data. The terminal offices 3a-3n connected to a transmission line 2 discriminates the ON of the transmission bit of the transmission format data from the address of an terminal office. The designated terminal office 3a transmits the terminal office state information to the line 2 within the designated time and based on the transmitting data given from the station 1. In this case, the transmission bit is set at ''0'' (OFF) for the reception data format, and accordingly the data form at is received only at the station 1. After the communication to the office 3a is over, the terminal offices are successively scanned in the same way to collect the data.
