Referring to Figure 5 attached to the character information conversion service processing operation in the subscriber board 14 mounted in the additional communication system according to the present invention configured as described above are as follows.

First, a PC user creates a character information, that is, a text file using an edit program, and then sends the text file to the additional communication system using an e-mail or a file transfer protocol, and simultaneously provides the text file. Enclose and send out the information of the service subscriber to be done.

Then, the central processing unit 21 of the subscriber board 14 mounted on the additional communication system monitors the LAN interface unit 23, analyzes the character information transmitted from the PC (step S1), and provides a service for providing the information. Identify who the subscriber is and how much information to provide.

At this time, according to the amount of text information to be provided to the service subscriber, it is determined whether the text information is to be converted during call setup or converted to voice or fax image in advance (step S2).

If the character information is converted during call setup, the central processing unit 21 of the subscriber board 14 stores the character information transmitted from the PC, that is, the text file of the ASCII code through the storage interface unit 27. If the call generation information is received from the MPU board 11 after being stored in the reception state (step S3) (step S3) (step S4), it is stored from the storage device 15 through the storage device interface unit 27. The service voice guide data indicating that the received text information exists is read and sent to the PCM highway through the voice synthesizer 26 and the PCM voice interface 22 to notify the service subscriber that the received text information exists ( Step S5).

When the subscriber of the service selects the voice or fax image service by inputting a predetermined button according to whether the received text information is provided by voice or fax image, the DTMF detection unit 24 of the corresponding subscriber board 14 is selected. ) Detects and reports to the central processing unit 21 the DTMF signal generated according to the predetermined button input of the service subscriber (step S6).

In this case, when the service subscriber to provide the text information uses the terminal for voice call or when the voice service is selected by the service subscriber, the text file is transferred to the TTS conversion unit 28, and the corresponding service. When the subscriber uses the terminal for fax communication or when the fax image service is selected by the service subscriber, the text file is transferred to the TTF conversion unit 30.

Thereafter, the central processing unit 21 of the subscriber board 14 is in a waiting state for receiving call generation information from the MPU board 11 (step S13). 15, the service voice guide data indicating that there is text information received from the user is read and transmitted to the voice synthesizer 26 through the buffer 42. Accordingly, the voice synthesizer 26 receives the received service voice guide data. Is synthesized and sent to the PCM highway via the PCM voice interface unit 22 to notify the service subscriber that the received text information exists (step S14).

When the service subscriber requests transmission of the text information, the central processing unit 21 of the subscriber board 14 stores the voice interface or the fax image data corresponding to the text information requested for transmission. After reading from the storage device 15 through the corresponding PCM interface unit 22, 31 to the PCM highway, the received text information is provided to the service subscriber as a converted voice or fax image ( Step S15).

Meanwhile, in the processing operation for the character information selectively serviced by the subscriber board 14 described above, each buffer and data bus control is managed by the central processing unit 21, and at the same time, the central processing unit 21 processes the service. The result is monitored and provided to the system administrator through the UART port of the UART monitoring unit 29.

In addition, when the subscriber board of the additional communication system according to the present invention checks in the central processing unit 21 who is a service subscriber who will provide the received text information, the subscriber board reports this to the upper MPU board 11, thereby providing the corresponding MPU board. 11, in conjunction with the trunk card 12, informs the service subscriber that there is received text information.

As described above, according to the present invention, when a specific subscriber prepares the character information to be provided to the service subscriber in a text file of ASCII code and transmits the text information to the additional communication system, the subscriber board 14 of the additional communication system may select the service subscriber. Accordingly, the TTS converter 28 or the TTF converter 30 converts the corresponding text information into a voice or a fax image and provides the service subscriber with the corresponding text information.
