In Fig. 3, when extension telephone 1a makes a call to extension telephone 1b and extension telephone 1b is set to be absent, or when extension telephone 1a or 11] makes a call, the other party's extension is not implemented. state, etc., the central control device 6 detects the state, connects the calling side telephone 1a, etc. and the notification sound storage device 4, and also connects the communication path control device to activate the notification sound storage device 4. Control the common sense.

Therefore, an audio signal for notifying disconnection from the notification sound storage device 4 is output to the calling side extension telephone 1.1, etc., and the caller from the calling side extension telephone 1a etc. is connected to the other party's extension telephone. It is possible to know what is not done.

Problems to be Solved by the Invention However, in the above-mentioned conventional electronic exchange, in order to notify a disconnection when a disconnection factor occurs by one notification sound storage device 4, it is difficult to notify the disconnection. However, there is a problem in that it is not possible to notify the details of the cause of the disconnection.

In view of the above-mentioned problems, an object of the present invention is to provide an electronic exchange that is capable of notifying a disconnection when a disconnection factor occurs and also notifying detailed contents of the disconnection factor. .

Means for Solving the Problems In order to achieve the above object, the present invention provides a storage means for storing the notification time of the notification sound depending on the disconnection factor,
Detects the cause of disconnection when it occurs,
The notification time of the notification sound corresponding to the detected disconnection factor is read from the storage means, and the notification sound is output to the calling side telephone during the read notification time.

According to the present invention, with the above configuration, it is possible to notify the disconnection based on the duration of the notification sound, and also to notify the detailed content of the cause of the disconnection.

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the electronic exchange according to the present invention, FIG. 2 is a flowchart 1 for explaining the operation of the electronic exchange shown in FIG. 1, and FIG. The same reference numerals are given to the same structural members.

In FIG. 1, 1a and 11) are extension telephones connected to this electronic exchange, 221.21) are power single-person circuits for connecting extension telephones 1a and 11), respectively, and 3 is a subscriber circuit. User circuit 2. 1, 21) to 5 to 7. This is a communication path switch for connecting the extension telephones 1a and 1b to the central office line circuit (not shown) and the notification sound storage device 4 through an exchange connection.

The notification sound storage device 4 stores in advance information for generating a disconnection notification sound to the calling party's extension telephone when a disconnection factor occurs.

Further, 5 is a communication path switch 3 which receives input/output control signals from the subscriber circuits 2a, 2b, the central office line circuit, and the notification sound storage device 4.
The communication path control device 6a is a central control device that controls the entire electronic exchange.

7 is a notification time storage device in which the notification time of the notification sound is preset according to the cause of disconnection, such as when the other party's extension telephone is set to be absent or the other party's extension is not installed; , 8 is a clock circuit for counting the notification time of the notification sound.

Next, the operation of the above embodiment, particularly the operation of the central control unit 6a, will be explained with reference to FIG.

In step 11, for example, when the extension telephone 1a makes a call to another extension telephone, the process proceeds to step 12, and the cause of disconnection is that the other party's extension telephone is set to be absent, or the other party's extension is not installed. Determine whether or not there is. If there are no disconnection factors, the process branches to step 13, and the call path control device 5 is controlled to call the other party's extension telephone and establish a mutual connection.

On the other hand, if these disconnection factors exist, step 14
In step 15, the notification time corresponding to the detected disconnection factor is retrieved from the notification time storage device 7, and in the subsequent step 15, the notification time is set in the clock circuit 8.

In step 16, the call path control device 6 is controlled to connect the calling side extension telephone 1a and the notification sound storage device 4 and to activate the notification sound storage device 4, and sends a disconnection notification sound to the calling side telephone 1a. send it out.

In the following step 17, the clock circuit 8 is used to monitor whether or not the set notification time has expired. When the time has expired, the process proceeds to step 18, and the communication path between the calling side extension telephone 1a and the notification sound storage device 40 is disconnected. At the same time, the drive to 7 of the notification sound storage device 4 is stopped.

Therefore, according to the above embodiment, when the central control device 6a detects a disconnection factor, the caller can control the duration of the notification sound in order to control the notification sound to continue for a period of time corresponding to the factor. It is possible to know the cause of the disconnection.

In addition, in the example described above, the case of making an internal call was explained, but it can also be applied to cases such as making an external call. The present invention can be applied not only to correct dialing operations such as when an extension is not installed, but also to disconnection factors such as dialing errors.
