Abstract

The present invention relates to a facsimile reception method that allows a user to receive a call and a fax from another office by connecting a line to a pre-entered phone number for an incoming call and a fax. The phone line is turned on and off by connecting to the telephone line fax when the ring is detected. Then, when the ring tone is detected, the telephone line is transferred to the interface by dialing the input telephone number. Connect to the line fax and set the return dial function when DTMF is detected, and save the phone number.If a ring is detected, connect the telephone line to the fax line and turn the phone line on and off.If the ring tone is detected, dial the stored phone number. Entering a phone number with an external telephone to switch the telephone line. Hayeoseo done.

The present invention relates to a facsimile reception method, and in particular, by connecting a line to a pre-input telephone number for incoming calls and faxes in the facsimile to the local exchange, so that the office and the fax can be immediately received. In general facsimile, telephones and faxes are only received at a certain place, and the user may not know the contents when the user is absent. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned shortcomings, and an object thereof is to provide a reception method for connecting a telephone or a fax to a place where a user is in the absence of the user. Hereinafter, an embodiment of the present invention for achieving such an object will be described in detail with reference to the accompanying drawings. First, FIG. 1 is a block diagram of the present invention, a line switching unit 1 for connecting a telephone line to a telephone or facsimile where a user is located, and a ring and DTMF detecting unit 2 for detecting a telephone ring tone and DTMF signal coming from the telephone line. And a processor for controlling the system by receiving a signal from the ring and DTMF detection unit 2 and the telephone line control unit 3 to control a telephone line switched by the line switching unit 1. (4), a memory (5) interconnecting the processor (4) to store the main information for controlling the system, and an interface (6) connected to the processor (4) to connect the user and the system do. The present invention configured as described above can be divided into a case in which a user inputs a phone number to the interface unit 6 and a case of inputting a phone number to an external telephone, as shown in FIG. 2 (a) and (b). First, a case in which the user inputs a phone number to the interface unit 6 will be described. The user selects a function of allowing the fax to return a dial in advance and inputs the phone number to be called into the interface unit 6. In this state, when there is a call from the sender, the ring and DTMF detection unit 2 detects a ring signal, and the processor 4 connects the line of the line switching unit 1 to the fax through the telephone line control unit 3. . Next, the processor 4 turns off the telephone line for a predetermined time in order to perform the input function and then connects it again. Then, the ringtone is heard from the exchange, and then dials the telephone number previously input by the telephone line control unit 3, which is connected to the place where the user is located by the exchange. On the other hand, when entering a telephone number with an external telephone, the user can enter a telephone number and a function that allows the fax to return dial with a predetermined TEN-KEY at another office on the premises. The detection unit 2 recognizes this and stores it in the memory 5. Then, when there is a call to the sender, the ring and DTMF detection unit 2 detects the call signal, connects the line of the line switching unit 1 to the fax side, and the telephone line control unit 3 turns off the telephone line for a certain time. Reconnect. Then, the ringtone comes in from the exchange, and then dials the telephone number stored in the memory 5 by the telephone line control unit 3 and connects the line to the place where the user is located by the exchange. As described above, the present invention allows a user to directly enter or return an external dialing function and another office telephone number so that the absentee can directly receive a call and facsimile from another office. There is an effect to increase.

Claims (1)

The user enters the return dial function and the telephone number into the interface unit, and if a ring is detected, connects to the telephone line fax side and turns the telephone line on-off. Enter the key, and if the ring is detected, connect to the telephone line fax, set the return dial function when the DTMF is detected, store the telephone number, and if the ring is detected, connect to the telephone line fax. And when the ring tone is detected, dialing the stored telephone number and inputting the telephone number to an external telephone for switching the telephone line.
