The signal applied from C1) is ANDed to detect whether the ordinary telephone is off-hook and outputs a high level detection signal to the signal input unit 27 when the ordinary telephone is off-hook.

As described above, the DTMF signal processing unit 25 converts the DTMF signal applied through the line interface unit 22 from the ordinary telephone into a digital signal and outputs the digital signal to the wireless transceiver 10 side, and determines whether or not the ordinary telephone has a dial button input. The signal to be output is output to the signal input unit 27 side, and the digital signal output to the wireless transceiver 10 side is output through the terminals D0 to D3, and the dial button input indicator is output to the signal input unit 27 side. The signal is output through the terminal DV. When a specific button (for example, a "*" button) of a general telephone is input, the DTMF signal processing unit 25 outputs a signal of "1, 0, 1, 1" through the terminals D3-D0.

In addition, the specific button detector 26 is composed of a plurality of buffers B1 to B3, an inverter I3 and an end gate G2, and the buffer B1 is connected to the terminal D0 of the DTMF signal processor 25.

When the specific button of the general telephone is input, the high-level detection signal is output to the signal input unit 27 by logically processing the signal.

The signal input unit 27 receives the signals from the hook state detecting unit 24, the DTMF signal processing unit 25, and the specific button detecting unit 26 via the terminals A0 to A2 to interface with each other. The CPU 28 recognizes that the ordinary telephone is off-hook when the signal of "0, 0, 1" is applied to the terminals A0-A2 of the signal input unit 27, and guides the memory unit 29. When voice data is taken out and outputted to the D / A converter 30, a voice service is performed. When a signal of "x, 1, x" is applied to the terminals A0 to A2 of the signal input unit 27, a normal telephone is used. Recognizing that the button is input, the voice service is stopped, and when a signal of “1, 1, ×” is applied to the terminals A0 to A2 of the signal input unit 27, the wireless transceiver 10 recognizes that a specific button is input. Outputs a signal instructing the transmission of a telephone number.

Referring to FIG. 2, the operation performed when the wireless transceiver connection interface system of the present invention configured to have the functions described above transmits and transmits a telephone number dialed through a general telephone to the wireless transceiver 10 side. As follows.

First, the CPU 28 monitors whether or not the ordinary telephone is off-hook (step 41). At this time, when the ordinary telephone is off-hook, the line interface 22 is connected to the terminals 0 through 1 through terminals C0 to C2. Since a 0 "signal is output, the hook state detection unit 24 outputs a high level signal to the terminal A2 of the signal input unit 27 based on the corresponding signal, and the specific button detection unit 26 and the DTMF signal processing unit. The reference numeral 25 denotes a low level signal to the terminals A0 and A1 of the signal input unit 27, whereby the CPU 28 is applied to the terminals A0 to A2 of the signal input unit 27. Based on the 1 "signal, the off-hook of the ordinary telephone is recognized.

When the CPU 28 recognizes the off-hook of the ordinary telephone, the voice service is started and the guide voice data of the memory unit 29 is fetched and the D / A converter 30, the amplifier 31, and the line interface 22 And the voice service are started by transmitting to the general telephone side via the transformer 21 (step 42). At this time, the guide voice data withdrawn from the memory unit 29 outputs "When dialing with a general telephone, all the phone numbers must be entered, and then a specified specific button must be input, and those who are familiar with the voice guide contents are guide voices. May be dialed before the end of the process. "

On the other hand, the CPU 28 checks whether a button of the ordinary telephone is input by checking whether a high level signal is applied to the terminal A1 of the signal input unit 27 while the voice service is performed to the ordinary telephone ( Step 43), when a low level signal is applied to the terminal A1 of the signal input unit 27, it is recognized that the button of the ordinary telephone is not input, and a high level signal is applied to the terminal A1 of the signal input unit 27. When authorized, it recognizes that a button of a regular telephone is input.

If the button of the desk phone is not input in step 43, the CPU 28 continues the voice service to the desk phone (step 44). If the button of the desk phone is input in step 43, the voice service for the desk phone is stopped. After that (step 45), it is checked through the signal input unit 27 whether a specific button input detection signal of the ordinary telephone is applied (step 46). The DTMF signal of the telephone number dialed and applied by the ordinary telephone is converted into a digital signal by the DTMF signal processing unit 25 and applied to the wireless transceiver 10 side. In step 46, the specific button of the ordinary telephone is not input. This means that the telephone number has not been dialed completely. At this time, the telephone number converted into the digital signal by the DTMF signal processing unit 25 is sequentially applied to the wireless transceiver 10 and stored (step 47). When the CPU 28 confirms the input of the specific button of the ordinary telephone in step 46, it considers that all telephone numbers are dialed, and outputs a signal to the wireless transceiver 10 to indicate that the telephone number is to be transmitted. By sending the number (step 48), the call channel can be connected.

On the other hand, when a call from the other party is generated through the wireless transceiver 10, the wireless transceiver 10 outputs a ring signal to the general telephone side via the audio signal processor 23 and the line interface 22, When the ordinary telephone is off-hook, a call is made while transmitting and receiving an audio signal with the general telephone side via the audio signal processing unit 23 and the line interface unit 22.

As described above, the present invention can cope with the telephone numbers of various regions with a very simple circuit configuration when the wireless transceiver and the ordinary telephone are connected to transmit the dialing telephone number applied from the ordinary telephone to the wireless transceiver. Thereby improving economics and productivity.
