いても良いことは勿論である。FIG. 1 is a block diagram showing an embodiment of a multi-terminal communication control device according to the present invention. In the figure, L is a telephone line, 100
Is a multi-terminal communication control device, 12 is a data terminal such as a personal computer, 11 is a telephone, and 13 is a facsimile. The multi-terminal communication control device 100 includes one station line terminal T 1 connected to the telephone line L, a telephone 10 and a facsimile.
Extension communication terminal connection terminal connected to communication terminals such as 11
T 2a , T 2b , T 2c , ringing signal detecting means 1, loop closing means 2, ringing tone broadcasting means 3, selection signal (CNG signal)
It is composed of a detection means 4, a time monitoring means 5, a control circuit 6, a calling signal carrying means 7, and connection contacts 8, 9, 10. 2 is a flow chart showing the structure of a program in the control circuit 6, FIG. 3 is a waveform diagram of a CNG signal of a facsimile, and FIG. 4 is a waveform diagram showing an example of a pseudo ring tone used in the present invention. Fig. 5 shows CNG of facsimile
The operation | movement explanatory drawing at the time of sending out the pseudo ringing tone when the rising of a signal is detected is shown. The CNG signal of the facsimile is 1100Hz as shown in Fig. 3.
The signal is used for 0.5 sec on and 3 sec off, and the pseudo ring tone according to the present invention is 40 seconds as shown in FIG.
It is used so that a 0 Hz signal will be on for 1 sec and off for 2 sec, and will be on for 32 msec and off for 40 msec during the period of 1 sec on. A multi-terminal communication control device according to the present invention will be described below with reference to FIGS. 1 to 5. First, the operation when a call is received from a caller who does not know that the multi-terminal communication control device according to the present invention is installed will be described. In this case, when in the initial state (step),
When the caller dials the telephone number, the calling signal detecting means 1 detects the calling signal sent from the exchange (not shown) through the telephone line L (step). As a result, the loop closing means 2 is operated to establish a communication path between the caller side and the multi-terminal communication control device 100 to make a temporary response (step). After that, the ringing tone transmitting means 3 is operated to transmit the pseudo ringing tone shown in FIG. 4 to the calling side, and at the same time, the time monitoring means 5 is operated to activate the timer (step,). The ringing tone uses the signal shown in FIG. 4 in order to eliminate the difference from the ringing tone heard by the caller before the multi-terminal communication control device 100 makes a temporary response. While the ringing tone is being sent, the selection signal detecting means 4 does not detect the CNG signal to be sent when the calling side facsimile automatically makes a call as shown in FIG. 3 even if a predetermined time has passed by the time monitoring means 5. And (step,), the connection contact 8 is closed to the calling signal transmitting means 7 side (step 8).
At the same time, the calling signal sending means 7 is operated to send a calling signal (step) to call the telephone 11. When the telephone 11 answers (step), it controls the ringing tone transmitting means 3 and the ringing signal transmitting means 7, stops the ringing tone and ringing signal transmission (step), and closes the connection contact 8 to the telephone line L side. This enables the telephone 11 to make a call (step). In this way, after the communication path between the caller side and the multi-terminal communication control device 100 is established, a pseudo ringing tone is immediately transmitted, and the telephone 11 is detected if the CNG signal is not detected within the predetermined time. By making the connection, the caller does not need to be aware of the multi-terminal communication control device 100.
It becomes possible to call 1. Next, a case where the CNG signal is transmitted during the transmission of the pseudo ringing tone after the provisional response will be described. In this case, after the loop is closed, the ringing signal sending means 3 is operated to send out a pseudo ringing sound to the calling side and at the same time the time monitoring means 5
Is up to the point where the timer operates. Then, when the CNG signal is detected by the selection signal detecting means 4 within a predetermined time (step),
The selection signal detecting means 4 notifies the rising edge of the CNG signal to the control circuit 6, and the control circuit 6 controls the ringing tone sending means 3 to stop the sending of the pseudo ringing tone (step). Thus, by stopping the pseudo ringing tone, even when the pseudo ringing tone a and the CNG signal b overlap, the signal input to the selection signal detecting means 4 becomes as shown in FIG. After detection of CNG signal, only the CNG signal is present, so that the ON determination of the CNG signal can be stably performed in a time with a sufficient margin. Then, the control circuit 6 controls the CNG signal based on the signal from the selection signal detecting means 4 for a predetermined time (CNG).
Since the signal is transmitted as a continuous signal of 500 msec as shown in FIG. 3, this predetermined time is set to, for example, 300 msec.) The CNG signal is judged to be ON by continuous detection, and the connection contact 10 is called. The signal transmission means 7 is closed (step). At the same time, the calling signal sending means 7 is operated to send the calling signal (step), and the facsimile is sent.
Call 13. When the facsimile 13 responds (step), the calling signal sending means 7 is controlled to stop sending the calling signal (step), and the connection contact 10 is closed to the telephone line L side to enable communication by the facsimile 13 (step). ). In the above description of the embodiment, the operation when the CNG signal is used as the selection signal for designating the normal terminal has been described, but it goes without saying that other signals such as the PB signal may be used as the selection signal. Is.

上を図ることができる。According to the present invention, when a communication path with the calling side is established and a temporary response is made, a pseudo ringing tone is sent to the calling side, and a selection signal for designating a communication terminal even while sending the pseudo ringing tone. When the selection signal is detected within the predetermined time, the specified communication terminal is called, and when the selection signal is not detected, the predetermined communication is performed. Since the terminal is configured to be called, even a caller who does not know that the device according to the present invention is installed can call a predetermined communication terminal without being aware of the device, and can also make a call. By sending a selection signal for designating a communication terminal on the side, the target communication terminal can be called and the mutual services of users can be improved.
