TECHNICAL FIELD The present invention relates to a voice mail device, and in particular, by setting a switch characteristic value for each telephone circuit line, the operation of connecting a different type switch for each telephone line of a voice mail device to connect and operate a plurality of different type exchangers to a single voice mail device. It is about a method.

In general, in connecting an exchange to a voice mail apparatus, a telephone line of at least four lines to a maximum of 128 lines is connected to a local or private exchange having different characteristics depending on the place where the voice mail apparatus is installed. The exchanges have different characteristics depending on the type. For example, characteristics such as a transmission time of a DTMF (Dual Tone Multi-Frequency) signal and a transmission interval of the DTMF signal are different depending on the type of the exchange.

The voice mail device connects exchanges having the same characteristic value per device or board. That is, the conventional voice mail apparatus can be connected in two forms when the exchange is connected. The first is a case where a switch having the same characteristic value is connected in system units, and a switch having the same characteristic value is connected to all telephone lines which the system accommodates. The second is a case where the exchangers having the same characteristic value are connected in the board unit, and the exchanger having the same characteristic value is connected to the telephone rotation of 2 to 4 turns connected to one board. Therefore, when a telephone call is made between the voice mail apparatus and the general subscriber, the voice mail apparatus makes a telephone call through the exchange according to a characteristic value per system or board.

Such a conventional voice mail device connects exchangers of the same characteristic value by system unit or board unit. Therefore, a voice mail apparatus which connects exchangers having the same characteristic value by system unit has several kinds of exchangers having different characteristic values in one system. The voice mail apparatus which connects an exchanger having the same characteristic value on a board-by-board basis cannot connect several kinds of exchangers having different characteristic values to one board. Therefore, the conventional voice mail apparatus has a problem in that it is not possible to connect an exchange having a different characteristic value for each telephone line.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to connect other types of exchanges for each telephone line of a voice mail device to operate a plurality of different types of exchanges by telephone lines by setting exchange characteristics for each telephone line. The purpose is to provide a method of operation.

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

This is a flowchart illustrating the exchange connection operation process.

As shown in FIG. 1, the voice mail device 50 according to the present invention includes a switch connection board 30 for transmitting and receiving a voice signal to the telephone network side, a switch connection board 30 side, and a voice. A main board 40 for transmitting and receiving signals is provided.

The switch connection board 30 includes a switch matching section 31, a signal separation section 32, an analog / digital conversion section 33, a reception voice buffer 34, a digital / analog conversion section 35, a transmission audio buffer ( 36), the digital signal processor 37 and the service processor (38). In addition, the main board 40 includes a system processor 41, an auxiliary memory 42, and a main memory 43.

The switch matching unit 31 of the switch connection board 30 serves to match the switch of the telephone network. The signal separator 32 separates and transmits a transmitted / received voice signal, and transmits the analog received voice signal supplied through the exchange matching unit 31 to the analog / digital converter 33, and the digital / analog converter. The analog transmission audio signal supplied from 35 is transferred to the switch matching section 31 side. The analog / digital converter 33 converts the analog received voice signal supplied through the signal separator 32 into a digital received voice signal and outputs it to the received voice buffer 34, and the received voice buffer 34 is analog. The digital received audio signal supplied from the digital converter 33 is transmitted to the digital signal processor 37. The digital signal processing unit 37 compresses the digital reception voice signal supplied from the reception voice buffer 34, converts the digital reception voice signal into digital reception voice data, and transmits the digital signal to the service processor 38. The data is decompressed, converted into a digital transmission audio signal, and transmitted to the transmission audio buffer 36 side. The transmission audio buffer 36 transmits the digital transmission audio signal supplied from the digital signal processing unit 37 to the digital / analog conversion unit 35, and the digital / analog conversion unit 35 receives the transmission audio buffer 36 from the transmission audio buffer 36. The supplied digital transmission audio signal is converted into an analog transmission audio signal and output to the exchange matching unit 31 through the signal separation unit 32. The service processor 38 controls the digital transmission / reception voice data input / output between the digital signal processing unit 37 and the system processor 41 according to the DTMF signal input from the telephone network through the switch matching unit 31.
