あることを示すアイドル信号を送信する。FIG. 3 shows a sequence diagram of a data simultaneous command. A signal indicating the status of the simultaneous command and command data are transmitted from the master station to the slave station in the following sequence. First, a start signal for starting the slave station is transmitted for a certain period of time. Next, a command signal on which the command data is superimposed is transmitted for an arbitrary time. Finally, a termination signal for terminating the slave station is transmitted for a predetermined time. When the voice simultaneous command, the facsimile simultaneous command, and the data simultaneous command are not being executed, an idle signal indicating that the simultaneous command is in an idle state is transmitted.
【０００５】子局から親局へは、子局の受信正常・受信
異常を示す信号を定期的に送信する。[0005] From the slave station, a signal indicating normal or abnormal reception of the slave station is transmitted periodically to the master station.

【発明が解決しようとする課題】前述の従来技術には、
子局で受信エラーが発生した場合、当該時刻の指令デー
タが不足するという欠点があった。The above-mentioned prior art includes the following:
When a reception error occurs in the slave station, there is a disadvantage that the command data at the time is insufficient.
【０００７】本発明は、これらの欠点を除去し、子局で
受信エラーが発生した場合、当該時刻の指令データの再
受信を行うことを目的とする。An object of the present invention is to eliminate these drawbacks and to re-receive the command data at the time when a reception error occurs in the slave station.

It is the same as the prior art. A signal indicating the status of the simultaneous command and command data are transmitted from the master station to the slave station in the following sequence. First, a start signal for starting the slave station is transmitted for a certain period of time. Next, a command signal on which the command data is superimposed is transmitted for an arbitrary time. Finally, a termination signal for terminating the slave station is transmitted for a predetermined time. Further, when the voice simultaneous command, the facsimile simultaneous command, and the data simultaneous command are not executed, an idle signal indicating that the simultaneous command is in an idle state on which the previous command data is superimposed is transmitted.
【００１１】子局から親局へは、子局の受信正常・受信
