Abstract

PURPOSE:To inform the user that the system is not in service by providing a means returning a fault message to an incoming from a telephone subscriber line when a host processor is faulty. CONSTITUTION:When a line control section 11 detects normally an incoming, a main control section 14 transmits a voice data for response from a voice memory 12 to a voice processing section 13 according to the command of the host processor, the voice data is converted into an analog signal and transmitted to a subscriber line 4. On the other hand, if the processor 15 is faulty, a fault display signal is transmitted from a fault display section 16 to the main control section 14 and when the line control section 11 detects an incoming call in this state, the main control section 14 starts automonously the voice processing section 13 so as to a fault message stored in advance in the voice memory 12 to the subscriber line 4.

Description

TECHNICAL FIELD The present invention relates to a voice response device that is connected to an exchange via a subscriber line and sends voice signals to the subscriber line according to instructions from a host processor.

PRIOR ART A conventional voice response device is connected to an exchange l by a subscriber line 4, as shown in FIG. When a service request is received via a4, the necessary voice response signal is sent out according to instructions from the host processor 3, but if the host processor 3 becomes unable to provide service for some reason, it will not respond even if there is a request from the telephone line. I can't.

That is, there is a drawback that there is no response when the host processor fails.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art, by providing a system which, when the host processor is in failure, returns a message indicating that the host processor is inoperable in response to an incoming call from a telephone subscriber line. An object of the present invention is to provide a voice response device that notifies a user that the system is unavailable for service.

Configuring the Invention The voice response device of the present invention comprises a voice memory storing voice messages, a voice processing section for transmitting the voice messages stored in the voice memory as a voice signal according to instructions from a host processor, and a subscriber line. A voice response device is equipped with a line control unit that is connected to an exchange via an exchanger and performs incoming call detection, response, etc., and receives instructions from a host processor and a fault indication signal from the host processor to control the operation of the voice processing unit, etc. a main control unit, the voice memory stores a predetermined failure message, and when the line control unit detects an incoming call and the main control unit receives a failure indication signal, the voice memory stores a predetermined failure message; It is characterized by transmitting the stored failure message as a voice 4f.

Embodiments of the Invention Next, the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

That is, a line control unit 11 connected to the subscriber line 4, a voice memory 12 storing voice data necessary for the voice response service and a failure message sent to the line by the host processor 15 in the event of a failure; Audio processing unit 13 that reads audio data, converts it into an audio signal, and outputs it
and a main control section 14 that controls these operations based on instructions from the host processor 15. The main control unit 14 and the host processor 15 are connected by a host processor connection bus. Host processor 15 controls voice response device 2 to make necessary voice responses. When the host processor 15 has a failure, the failure display unit 16 detects the abnormality of the host processor 15 and sends a failure indication signal to the main control unit 14 through a line different from the host processor connection bus.

Next, the operation of this embodiment will be explained. Normally, when the line control unit 11 detects an incoming call, the main control unit 14 is notified, and the main control unit 14 transfers response voice data from the voice memory 12 to the voice processing unit 14 according to instructions from the host processor 15.
3, the audio processing section 13 converts this audio data into an analog audio signal and sends it to the subscriber's mouth via the line control section 11! Send on 14th. However, when the host processor 15 has a fault, a fault display signal is sent from the fault display section 16 to the main control section 14, and in this state, the line control section 11
When the main control unit 14 detects an incoming call, the main control unit 14 autonomously activates the voice processing unit 13 to read out a fault message pre-stored in the voice memory 12, and sends the fault message to the subscriber line 4 as a voice signal. let The telephone subscriber on the calling side can know that the service is not available through the voice message described in item 1-1.

According to the present invention, when a call is received from the line while the host processor is in an inoperable state, the voice response device is configured to autonomously send a fault message to the line. Therefore, in the event of a failure of the host processor, it is possible to notify the user that the service cannot be provided.
