Zusammenfassung:PROBLEM TO BE SOLVED: To cause a ready device to discriminate an instruction via a public line from an instruction via non-public line.SOLUTION: The communication apparatus includes: a reception section; a determination section; a generation section; and a transmission section. The reception section receives a telegraphic message transmitted to a node. The determination section determines whether the telegraphic message received by the reception section includes an instruction relevant to a communication channel. When the determination section determines that the telegraphic message includes no instruction relevant to the communication channel, the generation section generates a non-via signal which represents that the telegraphic message is received via non-public line. The transmission section transmits the non-via signal generated by the generation section to the node. 【課題】レディ機器に公衆回線経由の命令と公衆回線非経由の命令とを判別させること。【解決手段】実施形態に係る通信装置は、受信部と、判定部と、生成部と、送信部とを具備する。受信部は、ノード宛に送信された電文を受信する。判定部は、受信部によって受信された電文が通信経路に関する命令を含むか否かを判定する。生成部は、判定部によって電文が通信経路に関する命令を含まないと判定された場合に、かかる電文が公衆回線非経由であることを示す非経由信号を生成する。送信部は、生成部によって生成された非経由信号をノードに送信する。【選択図】図2
