る。The modems 8a and 8b are duplexed to form the modems 8a1, 8a2, 8b1 and 8b2, so that even if one of the modems 8 cannot be used due to a failure or the like, the switching means 10 always duplicates the data. It is possible to take in the monitoring control information from the system in the operating state of the configuration. Also, the monitoring control information is transmitted in the opposite directions to the duplexed transmission path, and the first transmission means 5a and 5b and the second transmission means 6 are transmitted.
The monitoring control information of the other system can be exchanged via a and 6b so that the original state can always be equivalent to the operating state.

When the operation state is not the operation state, the first transmission unit 5a that receives and intercepts the monitoring control information received from the transmission apparatus 1b via the A route and the monitoring information from the transmission apparatus 1a, which is its own apparatus, cannot be transmitted to the host apparatus. And a second transmission means 6a. When viewed from the system B, the first transmission means 5b and the second transmission means 6b
It is provided similarly to the A-system first transmission means 5a.

０である。When the supervisory control state is exchanged with the upper-level device via the transmission means between the transmission device 1a and the transmission device 1b, the state shifts to the state depending on various conditions. The switching means 1 constitutes a path for exchanging with a higher-level device when the apparatus enters a stop state.

ことになる。That is, as shown in FIG. 7, the switching means 10 comprises a reception information branch circuit corresponding to the transmission apparatus 1a and the transmission apparatus 1b, and a means for forming each transmission information branch of the connection points a to f. For example, when the transmission device 1a is always operating and the transmission device 1b is in a standby state, the transmission device 1a is connected to the transmission lines of both routes via a → c → d → f corresponding to the transmission device 1a and transmits information to the higher-level device. Transmission will be performed. On the other hand, the standby transmission device 1b is not always in the operating state, but is connected to the transmission line via the reception branch circuit corresponding to the B system.

The device 1b can know and can notify the monitoring control device of the information even when the own system is in the operating state.

That is, as soon as the transmission device 1a, which has been in the constantly operating state for some reason, enters the failure state and enters the stop mode, the switching means 10 immediately changes the B route of the branch road from a → b,
The A route is switched to the side of d → e to bypass the service transmission device 1a. As a result, the transmission device 1b, which is normally in the backup mode and in the standby mode, shifts to the operation mode, and the transmission path to the higher-level device is also switched by the switching unit 1.

By the operation of 0, the B-system transmission device 1b that has been in operation receives control information even in a standby state, and transmits control information from a higher-level device in a state where the transmission device 1a has fallen due to a failure or the like in a healthy system. The data can be transmitted to the monitoring control device 2 via a certain transmission device 1b.

The connection of the monitoring control information is switched through the switching means 10. Therefore, even if one of the modulation / demodulation unit 8 and the transmission device 1 cannot be used due to a failure or the like, the switching unit 10 can always take in the monitoring control information from the system in the operating state of the duplex configuration. Further, since the monitoring control information is transmitted in the opposite directions to the duplexed transmission path, the monitoring control information of another system can be exchanged, and the original state can always be equivalent to the operating state.
