During the operation, the control and status display signal 103 from the station side is transmitted to the transmission device 101, and the signal required there is taken in as the control signal 105 for the local transmission device, and also the intra-station transmission device. A control and status display signal 106 is added to the home transmission device 102 via a control channel 109 on the transmission path as a signal for controlling the opposing home transmission device 102. The in-home transmission device 102 takes in a control signal 112 to be executed in the device, and a control / state display signal 111 from the in-home transmission device is further added and sent as a control / state display signal 115 to the terminal side.

柔軟性が乏しい欠点があった。In the above-mentioned conventional transmission control device, the control signal from the inside of the station to the home direction is transmitted through the transmission device in the station via the transmission path,
It is further transmitted from the home transmission device toward the terminal. On the contrary, the status display signal from the inside of the home to the inside of the office is further transmitted from the inside of the home transmitter to the inside of the office through the transmission line of the inside of the home transmitter. However, since the flow is one-way, the control signal from the intra-station transmission device further branches in the intra-station transmission device for control of the intra-station transmission device and further for control of the home transmission device via the transmission path. In the part to be transmitted, or in the intra-station transmission device, the state display signal transmitted from the in-home transmission device via the transmission line and the part to be merged in order to further convey the state display signal generated in the intra-station transmission device to the in-station direction. , The information must be clearly defined both logically and circuitally, and the control signal transmitted via the transmission line and the control signal processed by the intra-station transmission device are mutually related or transmitted. The status display signal transmitted via the path and the status display signal generated in the intra-station transmission device are related to each other, and there is a drawback that the flexibility of the format and arrangement of the signal is poor.
