2. Description of the Related Art Telephone lines laid from exchanges to homes are exposed to harsh external environments because they are laid from exchanges to homes such as through the ground or by overhead poles. However, if the telephone line is disconnected, users in each home will not immediately know that the telephone line is disconnected due to the disconnection, etc. After a while, I took the phone off-hook and realized that there was no dial tone, and judged that the telephone line seemed to be broken, so I used another telephone such as a public telephone to that effect. It is supposed to notify the telephone office.

In order to solve such a problem, there is a conventional method for detecting the disconnection of the telephone line, but this conventional detection method notifies a security company of the detected disconnection of the telephone line. The security company notifies the user of, for example, a mobile phone, and directly notifies the user.

[0004]

As described above, the conventional telephone line disconnection detecting means has a problem that it does not have a function of, for example, directly notifying the user of the disconnection of the telephone line.

The present invention has been made in view of the above,

When the mail sending unit 712 does not receive a response signal from the household device 2 in response to the line condition detection signal transmitted by the line condition detecting unit 711 to the household device 2,
IP the e-mail containing the line disconnection information indicating that the telephone line has been disconnected to the mail address that is the predetermined notification destination.
A disconnection information transmitting means for transmitting via the network 7 is configured. In addition, the email address that is the predetermined notification destination is
The mail address of the mobile phone 8, the landline phone 9, the PC terminal 10 or the like may be used.

In the telephone line disconnection notification system configured as described above, the line state detecting unit 71 of the monitoring server 71.
1 transmits a line state detection signal to the home device 2 at predetermined intervals via the IP network 7, the exchange 6, the D channel of the ISDN line 5, the DSU 4, and the TA 3.

When the home device 2 receives the line state detection signal from the monitoring server 71, it sends a response signal indicating that the signal has been received, TA3, DSU4, the D channel of the ISDN line 5, the exchange 6, and the IP network 7. Monitoring server 7 via
It returns to the line state detection unit 711 of No. 1.

When the monitoring server 71 receives the response signal from the household device 2 at the line state detecting section 711, the telephone line from the exchange 6 to the household device 2 is normally connected without disconnection. However, if the response signal from the home device 2 cannot be received by the line state detection unit 711 while repeating such an operation,
It was detected that the telephone line from the exchange 6 to the home device 2 was broken, and the telephone line was broken to a predetermined notification destination, such as a user or a maintenance center. An electronic mail including line disconnection information indicating that is transmitted via the IP network 7.

Then, the user of the communication system for disconnecting the telephone line, the maintenance center, or the like receives the e-mail including the line disconnection information by, for example, the mobile phone 8, the fixed telephone 9, the PC terminal 10, or the like, and The fact that the disconnection has been detected can be grasped promptly and accurately, and thus the broken telephone line can be quickly repaired.

The procedure of the telephone line disconnection notification method and the control method in the monitoring server of the above embodiment is recorded as a program in a recording medium such as a CD or FD, and the program recorded in this recording medium is used in the communication line. As a telephone line disconnection notification system and a monitoring server for performing the telephone line disconnection notification method and the control method, respectively, by downloading to a computer system via a computer or installing from a recording medium and operating the computer system with the program. Needless to say, it can be made to function, and by using such a recording medium, it is possible to enhance the distribution.

[0035]

As described above, according to the present invention,
The monitoring server sends a line status detection signal to the home device via the IP network, the exchange, and the D channel of the ISDN line,
When the response signal is not received, the line disconnection information indicating that the telephone line is disconnected is sent to the predetermined notification destination, so that the disconnection of the telephone line can be detected promptly and accurately, and it is the predetermined notification destination. For example, a user or maintenance center can be notified promptly, which enables quick repair of the telephone line, and calls or facsimiles from the outside for a while until it is determined that the call will not be taken due to a disconnection. It is possible to avoid the conventional inconvenience that it does not occur and to improve the telephone service.

Further, according to the present invention, the monitoring server is an IP
If a line state detection signal is transmitted to the exchange through the network and no response signal is received in response to the line state detection signal, line disconnection information indicating that the telephone line is disconnected is transmitted to a predetermined notification destination.
