BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital exchange system suitable for a small-scale digital exchange system or the like in which a maintenance person is not resident, and more particularly to a digital exchange system having a function of notifying a fault content by voice.

[0002]

2. Description of the Related Art Generally, in a small-scale digital exchange system, maintenance personnel are rarely stationed at all times, and once a failure occurs, it is necessary to call the exchange installation person before recovery. There was a problem that it often took time.

In addition, since the fault display function of the conventional digital exchange main body is often simple, various investigations are required to determine what kind of fault has occurred even if the exchange installer is called. There was a problem that it took an extra time to restore because it had to be carried out and then took a proper action depending on the content of the failure.

On the other hand, a method of grounding a so-called remote maintenance terminal has been conventionally known. However, this method has a drawback that the introduction cost of the entire system and the maintenance cost increase.

[0005]

As described above, in the conventional small-scale digital exchange system, the fault display function is insufficient. Therefore, even if the exchange installer is called, what kind of fault does it have? There is a problem that it takes a long time to investigate and discriminate, and as a result, it takes a lot of time to restore the system.

According to the present invention, this problem can be eliminated, and even a person who is not a maintenance specialist can properly understand the failure content of the system. By notifying this to the person who installs the digital exchange, appropriate measures and restoration can be performed. It is an object of the present invention to provide a digital exchange system capable of reducing time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are block diagrams of a digital exchange system according to the present invention. In particular, FIG. 1 is a diagram showing an internal configuration of the digital exchange in detail for convenience of explanation of operation when a light failure occurs, and FIG. It is a figure which shows in detail the internal structure of the notification device at the time of a serious failure, for convenience of operation description at the time of a serious failure.

As shown in these figures, the digital exchange 100 has a PBX control circuit 1 and a PBX control circuit 1 including a CPU and the like.
There are provided a call switch 4 for exchanging CM data, a voice synthesizing circuit 3 for creating a message at the time of failure, and interface circuits 21 to 2N connected to stations and various terminals.

Further, the serious failure notification device 200 has a PBX interface circuit 6 for receiving information from the digital exchange 100, a control circuit 7 for overall control of the serious failure notification device 200, and a voice storing various messages. A telephone interface 9 for interfacing with the response circuit 10 and the telephone 5 is provided.

Further, the line switching device 8 is configured so that the telephone 5 can be selectively switched and connected to the digital exchange 100 side and the serious failure notification device 200 side under the control of the serious failure notification device 200. .

Next, the operation of the digital exchange system having the above-mentioned configuration will be described in order for a light failure and a heavy failure.

First, a fault notification when a minor fault occurs will be described with reference to FIG. This minor failure is a failure such that only a specific line cannot be used, and means that the entire system is operating normally.

The PBX control circuit 1 periodically exchanges information with the interface circuits 21 to 2N, and constantly monitors whether or not a failure has occurred. In this state, when the PBX control circuit 1 detects the occurrence of a failure, the PBX control circuit 1 controls the voice synthesis circuit 3 to create a voice message, and the created message is converted into PCM data, It is sent to the call switch 4. The call switch 4 converts this PCM data into a time slot and sends it to the interface circuit 21.

At the same time, the PBX control circuit 1 instructs the interface circuit 21 to send a ring tone. Then, the interface circuit 21 sends a ringing tone to the telephone set 5, and when the telephone set 5 goes off-hook in response thereto, the ringing tone is stopped, and after that, the message PCM data from the call switch 4 is converted into a voice signal. It is sent to the telephone 5.

In this way, when a minor failure such as a disconnection of a specific line occurs, a voice message to that effect is sent to the telephone 5, which is a specific telephone constituting the terminal of the digital exchange. Since this voice message qualifies the failure that occurred in the exchange, by notifying the exchange installer of this, the exchange installer can immediately take the necessary measures, and the conventional system It is possible to significantly reduce the time required for failure recovery compared to.

Next, the fault notification when a serious injury occurs will be described with reference to FIG. The serious injury means a case where the digital exchange 100 does not operate normally due to a power failure of the digital exchange 100, a program operation abnormality, or the like.

When a serious injury occurs in the digital exchange 100, the PBX interface 6 in the serious injury notification device 200 receives the information and instructs the control circuit 7 of the failure mode. Then, the control circuit 7 operates the line switching device 8 to switch the telephone 5 to the serious injury notification device 200 side.

Next, the control circuit 7 instructs the telephone interface circuit 9 to send a ring tone, and in response to this, the telephone interface circuit 9 sends a ring tone to the telephone 5.

After that, the control circuit 7 waits for the off-hook signal of the telephone set 5, and when an off-hook signal arrives via the telephone interface circuit 9 thereafter, which message is to be transmitted according to the failure mode instruction from the PBX interface 6. The voice response circuit 10 is instructed to judge and send a message corresponding to the failure mode. The voice response circuit 10 reads the PCM data in the corresponding storage device (ROM or the like) according to the instruction of the control circuit 6 and sends it to the telephone interface circuit 9.

The telephone interface circuit 9 converts the PCM data from the voice response circuit 10 into a voice signal and sends it to the telephone 5.

As described above, when a serious injury occurs, a voice message corresponding to the serious injury is sent to the telephone 5, which is a specific telephone constituting the terminal of the digital exchange. Since this voice message appropriately informs the content of the serious injury, the content of the fault can be properly grasped based on this voice message even if not the maintenance specialist.

Therefore, by notifying the switch installer of this voice message, the switch installer can immediately take necessary measures, and the time required for failure recovery can be significantly shortened.

Although the contents of various messages have not been described in detail in the above embodiment, for example, "the power supply of the exchange has failed. In addition to a voice message such as “”, a notification using various tones or a display using a light emitting diode or the like can be appropriately adopted.

[0029]

As described above, according to the digital exchange system of the present invention, even if various troubles occur, the trouble contents are notified by an easy-to-understand voice message or the like. Can be grasped, and by notifying it to the person who installed the digital exchange, an appropriate response can be taken. Also, even if the digital switch installation side does not visit the customer to investigate the content of the failure, the failure mode is judged from the information from the customer, so there are advantages such as appropriate response and shortening of recovery time. is there.
