An object is to provide a communication system, a transmission apparatus, a line control apparatus, a line state monitoring method, a data output control method, and a program capable of, even when the radio relay apparatus is different from the line control apparatus, enabling the line control apparatus to recognize the radio line statuses. A communication system according to the present invention includes a radio transmission apparatus (103) that terminates a radio communication line (1), a radio transmission apparatus (105) that terminates a radio communication line (2), and a line control apparatus (101) that performs data communication with the radio transmission apparatuses (103 and 105). The radio transmission apparatuses (103) and (105) monitor the line states of the radio communication lines (1) and (2) and notify the line control apparatus (101) of the line states. The line control apparatus (101) controls data to be output to the radio transmission apparatuses (103) and (105) according to the line states. |
