(Example of connection judgment logic)
In the switching operation in the communication system of the present embodiment, the connection determination unit 130 of the control device 100 determines the connection state of the device on the user's home side. Therefore, an example of the connection determination logic will be described here. ..

As described above, the optical visualization PP 310 can detect an optical signal transmitted from the user's home side and notify the control device 100 of the optical signal as an electric signal. It should be noted that notifying the optical signal as an electric signal is an example, and the optical signal may be notified as an optical signal as it is. An electric signal or an optical signal notified from the optical visualization PP 310 to the control device 100 will be referred to as a notification signal.

The optical visualization PP 310 that has received the optical signal transmitted from the user's home-side device transmits a notification signal for the user's home-side device, and the connection determination unit 130 of the control device 100 receives the notification signal.

The connection determination unit 130 identifies the optical characteristics (eg, frequency, blinking cycle) of the optical signal transmitted from the user's home-side device from the notification signal, and based on the optical characteristics, the user who sends the optical signal. It is possible to identify whether the home-side device is an existing device or a new device. Regarding this identification, for example, the optical characteristics of the optical signal from the existing device received in the past are stored in the data storage unit 150, and the optical characteristics are compared with the optical characteristics of the optical signal to be determined. realizable. Further, the optical characteristics are stored in the data storage unit 150 in advance for each manufacturer, each device type, each device version, etc., and the optical characteristics of the optical signal to be determined are compared with the stored optical characteristics. The identification may be carried out with.

Further, the connection determination unit 130 of the control device 100 can communicate with the trap information indicating that the station building side device has detected the received light from the user home side device, and the station building side device can communicate with the user home side device. Receives trap information, etc. indicating the above from the equipment on the station building side.

Based on this information, the connection determination unit 130 can perform connection determination by, for example, the logic shown in FIG. The logic shown in FIG. 5 is only an example. In addition to the logic shown in FIG. 5, for example, the connection determination may be made only by the notification signal from the optical visualization PP310. Hereinafter, an example of FIG. 5 will be described.

As shown in FIG. 5, the connection determination unit 130 determines, for example, that the existing device 210 is connected on the user's home side based on the notification signal from the optical visualization PP 310, and from the station building side existing device 330. If it is determined that the existing device 330 on the station building side detects the received light from the existing device 210 on the user's home side and can communicate with the existing device 210 on the user's home side based on the trap information of the user's home side, the user's home side It is determined that the existing device 210 is connected to the existing device 330 on the station building side.

Further, for example, the connection determination unit 130 determines that the existing device 210 is connected on the user's home side based on the notification signal from the optical visualization PP 310, and uses the trap information from the existing device 330 on the station building side. Based on this, if the existing device 330 on the station building side detects the received light from the existing device 210 on the user's home side but determines that communication is not possible, the pattern is not applicable in the normal system, so N / A. (Not applicable). In this case, since it is assumed that a failure or malfunction has occurred, it may be determined as "failure".

Further, for example, the connection determination unit 130 determines that the existing device 210 is connected on the user's home side based on the notification signal from the optical visualization PP 310, and uses the trap information from the existing device 330 on the station building side. Based on this, if it is determined that the existing device 330 on the station building side does not detect the received light from the existing device 210 on the user's home side, the existing device 210 on the user's home side is not connected to the existing device 330 on the station building side. (That is, the state where the connection is not made in Robo PP320).

Further, for example, the connection determination unit 130 determines that the new device 220 is connected on the user's home side based on the notification signal from the optical visualization PP 310, and uses the trap information from the existing device 330 on the station building side. Based on this, if the existing device 330 on the station building side detects the received light from the existing device 210 on the user home side but determines that communication is not possible, the new device 220 on the user home side connects to the existing device 330 on the station building side. Judge that you are doing.

Here, it is assumed that the existing device 330 on the station building side can detect an optical signal from the new device 220 on the user's home side, but cannot communicate with the new device 220 on the user's home side due to differences in optical characteristics and the like. ing. However, the connection determination unit 130 determines that the new device 220 is connected on the user's home side based on the notification signal from the optical visualization PP 310, and is based on the trap information from the existing device 330 on the station building side. Even if the existing device 330 on the station building side detects the received light from the new device 220 on the user home side and determines that communication is possible, the new device 220 on the user home side is connected to the existing device 330 on the station building side. It may be judged that.

(Example of switching operation)
When the existing device 210 on the user's home side is switched to the new device 220 on the user's home side and the device on the station building side that communicates with the device on the user's home side is switched from the existing device 330 on the station building side to the new device 340 on the station building side by migration. An operation example will be described according to the procedure shown in FIGS. 6 to 10.

<Step 1: Fig. 6>
In step 1, as shown in FIG. 6, the user applies for device migration from the portal screen or the like displayed by the user IF unit 110 of the control device 100. The application information includes user identification information and a scheduled switching date and time, which are stored in the data storage unit 150. Based on the user's identification information, the operation control unit 140 determines that the user's existing device 210 on the user's home side can be switched to the new device 220 on the user's home side, and based on that determination, implements the NW design, and as a result, Is stored in the data storage unit 150. The result of the NW design includes, for example, connection switching information in the Robo PP320. The connection switching information is, for example, information indicating that the existing connection "user-side port A-station building device-side port X" is switched to the connection "user-side port A-station-building device-side port Y".

Further, the operation control unit 140 transitions to the migration waiting state. The migration waiting state is to wait until the current time reaches the "scheduled switching date and time" for the user. As shown in FIG. 6, the main signal is flowing between the existing device 210 on the user's home side and the existing device 330 on the station building side until the switching operation is started.

When the current time reaches the "scheduled switching date and time", the processes after step 2 are executed.

<Step 2: Figure 7>
In step 2, as shown in FIG. 7, the user removes the existing device 210 on the user's home side. That is, the existing device 210 on the user's home side is removed from the line (optical fiber) extending from the station building.

As a result, the optical visualization PP 310 does not detect the optical signal from the existing device 210 on the user's home side, and therefore issues a notification signal (alarm) indicating that. Further, since the existing device 330 on the station building side does not detect the optical signal from the existing device 210 on the user's home side, trap information (alarm) indicating this is issued. The connection determination unit 140 of the control device 100 receives these alarms, determines that the existing device 210 on the user's home side has been disconnected, and notifies the operation control unit 140 of the determination result.

<Step 3: Fig. 8>
In step 3, as shown in FIG. 8, the user attaches the new device 220 on the user's home side. That is, the new device 220 on the user's home side is connected to the line (optical fiber) extending from the station building. As a result, the optical visualization PP 310 receives the optical signal from the new device 220 on the user's home side, and transmits a notification signal indicating that the optical signal has been received to the control device 100. Further, the existing device 330 on the station building side transmits trap information indicating that the light received from the new device 220 on the user's home side is detected but communication is not possible to the control device 100.

The connection determination unit 130 of the control device 100 determines that the new device 220 is connected on the user's home side based on the notification signal from the optical visualization PP 310, and uses the trap information from the existing device 330 on the station building side. Based on this, the existing device 330 on the station building side detects the received light from the new device 220 on the user home side, but determines that communication is not possible. Therefore, the new device 220 on the user home side connects to the existing device 330 on the station building side. It can be determined that there is. The determination result is notified to the operation control unit 140.

<Step 4: Figure 9>
In step 4, the operation control unit 140, which has detected that the new user home side device 220 is connected, switches the connection to the Robo PP 320 so as to connect the new user home side device 220 and the measuring instrument 350. To instruct.

As shown in FIG. 9, the Robo PP 320 performs connection switching according to the instruction, and the new device 220 on the user's home side and the measuring instrument 350 are connected. Further, the motion control unit 140 instructs the measuring instrument 350 to carry out the opening test, and the measuring instrument 350 carries out the opening test. Here, the optical visualization PP 310 detects an optical signal flowing along with the opening test and emits a notification signal to the control device 100. The operation control unit 140 can grasp that the opening test is being carried out by the notification signal.

Here, the opening test by the measuring instrument 350 is successful, and information indicating the success is sent to the operation control unit 140 of the control device 100. As a result, the operation control unit 140 grasps that the transmission path between the new device 220 on the user's home side and the station building has been opened. When the opening is grasped, the process proceeds to step 5.

<Step 5: Fig. 10>
In step 5, the operation control unit 140, which has detected that the opening test for the new user home side device 220 has been successful, connects the new user home side device 220 and the new station building side device 340 to the Robo PP320. Instruct to perform connection switching.

As shown in FIG. 10, the Robo PP320 performs connection switching according to an instruction, and the new device 220 on the user's home side and the new device 340 on the station building side are connected. Further, the operation control unit 140 inputs the settings necessary for communication with the new device 220 on the user's home side to the new device 340 on the station building side. If the settings have already been input or if it is not necessary to input new settings, the settings may not be input here.

The optical visualization PP 310 receives an optical signal flowing between the new device 220 on the user's home side and the new device 340 on the station building side, and transmits a notification signal indicating that the optical signal has been received to the control device 100. Further, the new device 340 on the station building side detects the received light from the new device 220 on the user's home side, and transmits trap information indicating that communication is possible to the control device 100. From this information, the operation control unit 140 of the control device 100 can grasp that the switching is completed and the service provision by the device after the migration is started.
