In this configuration, the subscriber (s) must have a separate fax signal processor 7 to transmit and receive the fax signal.

If all of the computer users connected to the ISDN PRI subscriber module want to process the fax data, they need a 30-channel fax module that can handle the fax signal.

Therefore, the subscriber has to buy a separate fax transmission and reception module has a problem of cost increase.

Therefore, the present invention has been made to solve the above problems, it is equipped with ISDN PRI interface function and at the same time to enable the FAX transmission and reception using the DSP processing unit and FAX signal processing software without a separate fax data processing module and basically an industrial computer B The purpose is to develop a module in a general computer embedded form so that it can be used universally.

In accordance with one aspect of the present invention, there is provided a comprehensive subscriber network module including a facsimile signal processing unit. A controller in charge of overall control of the system; A memory unit for storing a program capable of reading and writing a series of command processes in the control unit; A switching unit for switching voice, data and fax signals to respective units; A digital signal processor for processing voice and fax signals; And a fax signal processing unit for processing fax data.

The digital signal processing unit may provide an automatic response function, an interactive voice response, and a fax message processing function with respect to the transmitted and received voice signals.

The fax signal processor may image the fax signal to be transmitted to the digital signal processor, and receive the imaged fax data received from the digital signal processor to restore the fax signal.

The integrated telecommunication network subscriber device module further comprises a computer interface for providing an interface with a computer, which is mounted inside the computer to have a plug and play (PnP) function.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

2 is a schematic block diagram of a module of an integrated telecommunication network subscriber device according to an embodiment of the present invention.

Referring to Fig. 2, the integrated telecommunication network subscriber device is constituted by the integrated telecommunication network subscriber module (M) connected to a telephone station, a private exchange, and a key phone (1).

The module (M) includes a line interface (11) connected to a telephone station, a private exchange, and a key phone (10) for interfacing voice, data and fax signals; A computer interface unit 12 for providing interfacing with a computer; A controller 13 in charge of overall control of the system; A memory unit 14 for storing a program capable of reading and writing a series of command processes in the control unit 13; A switching unit 15 for switching voice, data, and fax signals to respective units; A digital signal processing (DSP) processor 16 for processing voice and fax signals; And a fax signal processor 17 for processing fax data.

The computer interface unit 12 is equipped with a Plug and Play (PnP) function to automatically recognize a module when mounted in a computer.

Looking at the operation of the device configured as described above are as follows.

The ISDN PRI Subscriber Device Module (M), connected to a telephone company, private branch exchange, or keyphone, accepts an Automatic Response System (ARS), an Interactive Voice Response (IVR), a Fax Management System (ARS) for incoming calls. System can be configured with FMS: FAX Management System. In this configuration, the flow for the basic incoming call is interfaced through the line interface unit 11 when the incoming call message is received from the telephone station and sensed by the control unit 13. The control unit 13 determines the type of the call and connects it to the DSP processing unit 16 through the switching unit 15.

The DSP processor 16 plays the voice message corresponding to each service type for the incoming call. If the incoming call is not a voice signal but a fax signal, the DSP processing unit 16 connects the incoming call to the FAX signal processing unit 17.

The fax signal processor 17 restores a signal applied through the DSP processor 16 to an original image signal and provides the user with a fax data format.

Such a series of processes can be summarized as the following steps.

3 is a flowchart illustrating a call processing method of an integrated telecommunication network subscriber device according to the present invention.

Referring to FIG. 3, an initialization is performed by first turning on the power of a subscriber station (100).

When the initialization is completed, it detects whether there is an incoming call through the line interface unit 11 (110), and if an incoming call occurs, the incoming call is connected to the DSP processor 16 through the switching unit 4 (120). .

At this time, if the incoming call is compared to determine whether the voice signal is a voice signal, the DSP processing unit 16 processes the message corresponding to the service (ARS / IVR / FMS, etc.) for the function (140).

If the incoming call is not a voice signal in step 130, since the incoming call is a fax signal, the data processed by the DSP processor 16 is connected to the FAX signal processor 17 (150).

The FAX signal processor 17 provides the user with an image of the received data in the form of original fax data (160).

Thus, the fax signal processing unit is provided in the module of the integrated telecommunication network subscriber equipment, so that the subscriber (s) can use the fax service in addition to the voice service.
