Description of the Related Art A conventional transmission device having a redundant configuration in which a system 0 and a system 1 are duplicated has a problem that normal alarm transfer and switching control cannot be performed due to erroneous connection of cables between the devices. It was necessary to detect the state of the cable connection between the devices. However, in the conventional transmission line monitoring of the transmission device and the monitoring in the device, an erroneous connection of the cable between the devices cannot be detected. For this reason, erroneous connection of cables between devices has been conventionally detected by the following method. As shown in FIG. 5, the overhead data unique to the system is held inside the transmission line interface packages of both systems of the transmission device, and the internally held data is inserted into the overhead insertion unit (own station 0) by control from outside the device. System: 31, own station 1
System: 35, opposing station 0 system: 41, opposing station 1 system: 45), and the received data from the opposing device is overhead terminated (own station 0 system: 33, own station 1 system: 37, opposing station 0).
System: 39, opposing station 1 system: 43), and sends the internally held data corresponding to the received data to the opposing device through the overhead data insertion unit. By comparing the received data from the opposing device with the internally held data, Only when the comparison result does not match, is the line erroneous connection detection control unit (own station 0 system: 3
2, own station 1 system: 36, opposite station 0 system: 42, opposite station 1 system:
44), the detection result is transmitted to the line erroneous connection detection result notification unit (own station 0 system: 34, own station 1 system: 38, opposite station 0 system: 4).
2, the opposite station 1 system: 46).
As described above, in the related art, only the receiving side detects the erroneous connection between the devices.
