BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-premises exchange system having a voice accumulation function, and more particularly, to an on-premises exchange system that enables the accumulation of voice signals and regeneration services of accumulated voices using a general MFC telephone.

The voice accumulating device is also called a device having a function of transmitting and receiving voice information electronically, also called a voice mail.

The audio signal of a telephone or the like is converted into a digital signal and stored in an accumulator such as a magnetic disk. The audio accumulated digital audio data of the disk is converted into an analog signal and reproduced and output.

The conventional method of implementing the voice accumulation exchange system by connecting the voice accumulation apparatus to the exchange system merely provides a voice mail with a simple function by simply handling and controlling the voice accumulation apparatus as a subscriber of the exchange.

Accordingly, an object of the present invention is to perform a voice accumulation service for accumulating and reproducing a voice signal through an on-premises switching network using a general MFC telephone, and at the same time, to realize a function service according to the state of a general MFC telephone subscriber. The branch is in providing an exchange system.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a system diagram according to the present invention, which analyzes an input control signal to perform search control while conducting search control of an action related to the accumulation or reproduction of an audio signal, and the exchange control device ( A plurality of subscriber telephones 3a to 3N respectively connected to the time division switch 2 for performing switching operation by the exchange control of 1) and to the communication paths 10a to 10N which are input / output lines of the time division switch 2, respectively. Connected to each of the subscriber switchers 3a to 3N and the switching control device 1 to retrieve the state of each subscriber, and to decode the DTMF signal by pressing the function key to generate a function control signal. An interface device 4 provided to the exchange control device 1 and providing service of each subscriber, and a subscriber number and service class for a function control signal input through the exchange control device 1; Above information An input / output signal of the first communication control device 5 which outputs to the ring control device 1 and outputs an input function control signal as an interfacing signal, and the communication paths 20a and 20b of the time division switch 2; Analog / Digital (hereinafter referred to as A / D Converter) (6) and Digital / Analog Converter (hereinafter referred to as D / A Converter) for outputting the analog / digital and digital / analog conversion to the system bus 30 7) and a large-capacity auxiliary storage device 9 which stores the input / output data of the A / D and D / A converters 6 and 7 in the address area at a predetermined address by predetermined control and stores the voice accumulation data. A is connected between the first communication control device 5 and the system bus 30 to control the system bus 30 by a function control signal output from the first communication control device 5 so that the A Access the data of the / D, D / A converters 6 and 7 to the mass storage device 9, and a predetermined signal Consists of the second communication control unit 8 to output to the first communication control unit (5).

In the memory area of the interface device 4 as described above, a subscriber port state table for retrieving the state of each subscriber is set for each subscriber, as follows.

Port Status Table for Each Subscriber

In the configuration of FIG. 1, the dotted line 100 is the area exchange system area, and 200 is the speech storage device.

Hereinafter, the operation of FIG. 1 according to the present invention will be described in detail.

Now, in the system as shown in FIG. 1, when the subscriber of the MFC telephone 3a hooks off and presses various function keys to receive service of the voice storage device, this is inputted to the first interface device 4 via the call line 10c. do.

At this time, the first interface device 4 for monitoring the status of the subscriber detects the hook-off state of the subscriber 3a, records it in the port table as described above, and outputs a function key outputted from the MFC telephone 3a to the DTMF. It decodes and outputs the subscriber function status signal to the exchange control device 1.

The function status signal of the subscriber output from the interface device 4 is input, but the exchange control device 1 searches whether the input function signal is a function signal related to the accumulation or reproduction of the voice signal.

If the search result is a control signal of an action related to the accumulation or reproduction of the voice signal, the exchange control device 1 inputs it to the first communication control device 5, and controls the time-sharing switch 2 to hook off. The call path of the subscriber 3a is allocated to connect the call line 10a of the subscriber and the call line 20a of the voice storage device 200. For example, if the subscriber 3a calls the subscriber 3N, but the subscriber 3N is not answered, then the subscriber 3a inputs a voice accumulation function key. ) And the voice path 200 are formed.

When the voice signal for reproducing and accumulating the voice signal is output from the subscriber 3a in the above state, the A / D converter (i.e., through the call path 10a, the time division switch 2, and the call path 20a) is used. 6), which is input to the large capacity auxiliary storage device 9 via the system bus 30. At this time, the key press action of the subscriber 3a, which is the MFC phone, is detected by the interface device 4 and continuously reported to the exchange control device 1.

The exchange control device 1 for inputting the subscriber function signal output from the interface device 4 during the above operation analyzes the input signal and informs the voice storage device through the first communication control device 5. Transfer to the second communication control device (8). If the input subscriber function signal is not related to voice accumulation, the exchange control device 1 performs processing on the input function signal. For example, if a function key signal is related to a general call service service, the exchange service related thereto is performed.

On the other hand, the first communication control device 5 which inputs the function control signal of the subscriber from the exchange control device 1 is inputted to the second communication control device 8 to provide appropriate measures and services for the subscriber's actions. Let's do it. That is, the second communication control device 8 performs control by the input function control signal to save the voice data output from the A / D converter 6 to the large capacity auxiliary storage device 9.

If the voice accumulator 200 needs to transmit information of a predetermined state from the premises exchange system 100, a function control signal corresponding to the corresponding function control signal is generated from the second communication controller 8, which is the first communication. It is input to the control apparatus 5. At this time, the first communication control device 5 inputs an input signal to the exchange control device 1, and the exchange control device 1 determines and performs a process corresponding to the input signal.

When it is determined that the service of the MFC telephone subscriber 3a is terminated by the above-described operation, the exchange control device 1 informs the second communication control device 8 of the service termination through the first communication control device 5. After sending, disconnect the connection to the assigned call. Therefore, the voice accumulator 200 is controlled by transmitting information between the premises exchange system 100 and the voice accumulator 200 through the first and second communication controllers 5 and 8 and the exchange controller 1. By doing so, the following functions can be performed.

* Unanswered mail: If the called party (callee) is not answered, the caller will be automatically connected to the voice mail device to leave a voice mail.

* Missed mail: If you are away for a long time, you can connect to the voice mail device directly and leave the mail without connecting to the other party's phone.

* Memo during call: The function of recording the contents of two calls during the call with the other party.

* Incoming mail indication: If there is a mail received, the subscriber is notified of the received mail.

* Undelivered indication: Notifies the subscriber who requested to send it when it was not delivered to the requested e-mail.

* Network: Cuts mail from the voice accumulator to the memory of another voice accumulator.

As described above, the present invention can provide a voice storage service to a plurality of MFC subscribers of the premises exchange system by providing a communication control device in each of the premises exchange system and the voice accumulator. There is an advantage that can be used.
