RS-232C matching unit 33, which is automatically matched with the telegram automation terminal when data on the telegram transmission is supplied, and DC 24V voltage supplied from the power supply to the keyset side, and each circuit side It provides a bipolar / RS-232C interconverter characterized in that it comprises a DC / DC converter 34 for supplying a voltage of DC 5V required for.

In addition, the first step of transmitting the transmission data consisting of 80 bits from the electronic switch system side to the TIM side, and after performing the first step, the TIM reads the intermediate point of the supplied transmission data and receives the read data. A second step of transmitting to the keyset side and repeating the reading of the transmission data and the transmission to the keyset side until the 80-bit transmission is completed; and the transmission of the transmission data to the keyset side after the second step is completed, all frames A third step of supplying the received data from the keyset side or the data received from the telegraph automation terminal to the electronic switching system, and the completion of the data transmission to the electronic switching system after completion of the third step. In the fourth step, the keyset transmits the received data supplied from the electronic switching system to the TIM. When the transmission and reception between the electronic switch system and the keyset is completed after the fourth step, the TIM analyzes the received transmission data and automatically matches the telegram automation terminal via the RS-232C matching unit if the received transmission data is the calling number. The fifth step is made and the sixth step of transmitting the reception data supplied from the telegram automation terminal instead of the reception data supplied from the keyset when data is transmitted from the telegram automation terminal to the electronic switching system. It provides a bipolar / RS-232C interconversion method comprising a.

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

Figure 1 (a) is a connection diagram of the electronic switchboard system and the keyset according to the present invention, Figure 1 (b) is a connection diagram between the TIM and the electronic switch system according to the present invention. As can be seen in the figure, the TIM according to the present invention can be installed and used between the electronic exchanger system 10 and the keysets 20 and 22, and can be removed and used when it is not necessary. 2 is a configuration diagram of a TIOS Interface Module (TIM) according to the present invention, which includes a clock generator 30, a microprocessor 31, a bipolar / binary interconverter 32, an RS-232C matching unit 33, and a DC / DC. And a transducer 34. The clock generator 30 supplies the necessary clock to the microprocessor 31 side, and the microprocessor 31 operates according to the timing shown in FIG. 3 and is bipolar from the electronic switch system (TDX-ACD) and the keyset side. The reception information supplied through the / binary interconverter 32 is supplied to the telegram automation terminal through the RS-232C matching unit 32. The bipolar / binary interconverter 32 converts the bipolar signal received from the TDX-ACD and the keyset into a binary signal and supplies it to the microprocessor 31, and transmits it from the microprocessor 31. The supplied binary signal is converted into a bipolar signal and output to the electronic switch system and the keyset side. RS-232C matching unit 33 is automatically matched with the telegraph automatic terminal when a signal for telegram transmission is supplied from the microprocessor 31 side, and outputs the telephone number and telegram transmission signal of the called station to the telegram automatic terminal. do.
