It becomes possible to change the data of the changeable data item corresponding to the input ID number 21Aa (step S106).

Here, there are various conventionally known methods for changing the data of the data items that can be changed after the line is connected, for example, using a PB signal transmitted from the terminal handset, and therefore the detailed description thereof will not be given here.

On the other hand, if the terminal corresponding to the other party's telephone number is in the off-hook state (NO in step S105), a reply call cannot be made to that terminal, so the building management device 1 does not reconnect the line. The process ends.

As described above, the building management device 1 is operated from the terminal 5a.
When a correct ID number corresponding to the terminal 5a is accessed and the building management device 1 refers to the partial data 21A and dials the telephone number 21Ab corresponding to the ID number 21Aa, the building management device 1 and the terminal 5a 5a and the line are connected again. Then, the building management device 1 receives a data change input from the terminal 5a.

Further, even if the correct ID number recorded in the database 21 is input, if the ID number is not the ID number corresponding to the terminal that has input the ID number, the building management device 1 refers to the database 21. The terminal of the other party who redialed the telephone number corresponding to the ID number
The terminal is different from the terminal that has input the ID number. Therefore, the building management device 1 is not connected to the terminal that inputs the ID number.

Therefore, according to the first embodiment, the ID input from the terminal 5 to the building management device 1 via the line network.
