Abstract

The method comprises the steps of checking a dial tone and dialing so as to search whether the other party's facsimile is set to auto or manual, transmitting CNG tone and text according to T-30 protocol when the other party's facsimile is in auto receiving mode and checking ring back tone/busy tone when the facsimile is in manual mode, checking a ring back tone checking flag in case of ring back tone, cutting a line in case of busy tone and checking whether the ring back flag is or not if the tone is not ring back tone and busy tone, and inputting a subscriber number when the ring back tone flag is set or a predetermined time passes.

Description

How to handle fax connection and push button key press in mailing system

1, 2 is a system diagram applied to the present invention.

3 is a flow chart according to the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile mailing system, and more particularly, to a method for handling connection between a facsimile interface unit (FIU) and a receiving facsimile and a pushbutton key input in a document transmission.

1 and 2 is a system diagram to be applied to the present invention, it is found that the functions and features of each part thereof is described in detail in the application Nos. 87-2554 and 88-12785 filed by the same applicant Put it.

In the system shown in Figs. 1 and 2, there is a signal for automatic document transmission in the MCP (8) and in the automatic transmission mode by the FCP (10), and the facsimile for document reception is not busy in the automatic reception state. When the receiving facsimile transmits CNG tones, it is processed according to the T-30 protocol to achieve document communication between the sending and receiving facsimile. When the receiving facsimile is in the manual mode, when the FCP 10 receives a call according to the automatic transmission, the receiving facsimile user inputs a key button to receive a call tone and receive a document. That is, in the conventional facsimile, when the receiving side facsimile is in the manual mode, there is no security problem of the document because the document is transmitted without the counterpart being identified by the call by tone.

Accordingly, an object of the present invention is to guide a certain voice during manual in the automatic / manual setting of the receiving side facsimile, and accordingly, the receiver receives a document by inputting a key for selecting a function using the constant pushbutton key. To provide a way to help.

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

3 is a flowchart according to the present invention, in which a first step of searching for automatic / manual setting of a relative fax is performed by dialing while checking a dial tone by inputting manual / automatic selection as a dial start key, and in the first step A second step of checking a ringback tone / in-call tone by transmitting a CNG tone when the automatic reception mode is set, transmitting a document according to the T-30 protocol, and checking a tone in the reception mode; and the ringback tone in the second process. A third step of checking the checking flag according to the date and time, cutting the line when busy, and checking the presence or absence of the ringback tone flag for a period of time when the ringback tone and non- busy tone are not included; When a predetermined time elapses, a fourth process of voice messaging by inputting a subscriber number for voice guidance is performed.

It is entered into the FIU 11 via the FCP 10 from the MCP (8) with the command to enter the automatic / manual of the telephone number and the receiving fax. The automatic / manual reception of the receiving fax can be inputted at the time of set-up to the present system or from a system connected to the host computer from the HCP 13.

Accordingly, referring to the example performed with reference to FIG. 3, after receiving the dial start command, the FIU 11 completes the dialing in the process (2-1) after the modem setting. After the dialing is completed in the above step (2-1), the auto / manual check received from the MCP (8) is checked in the step (3-1). Send the signal in step (4-1), send the document after protocol exchange / data transfer in step (6-1) according to T-30 protocol in step (5-1), and transmit the line in step (7-1). Done.

However, if the receiver is a manual receiver in step (3-1), after completion of the dial, the tone is first checked in step (8-1) to check whether it is ring-back tone or busy tone in step (9-1). In the case of busy tone in the process of -1), the line is cut in the process of (7-1) as in the case of automatic and retry after a certain time.

In case of ring-backtone detection in step (9-1), the RBT detection flag is set in step (10-1) and the ringback tone flag is set or not set in step (9-1). In the state (12-1), check whether the RBT is terminated after a certain period of time, and when it is finished, immediately perform the voice service in (13-1) to allow the receiver to press the push button in the specific (14-1) process. You will be asked. When the tone check is not a ringback tone / business tone in the above process and passes a certain time in (12-1), it is considered as a connection failure and retries after disconnecting the line in (7-1).

The voice guidance of step (13-1) may vary depending on the service field of the system, and in most cases, a user number and a password are required to be input through a push button in step (13-1). After receiving the PB, the FIU 11 determines whether the received PB is buried in the process (15-1), and in the case of an incorrect PB, the voice prompts the user to press it again for several times through the process (17-1, 18-1). If a certain number of times is exceeded in step (18-1), the line is cut and terminated in step (7-1). If the PB is buried in step (15-1), the voice prompt to press the communication button of the facsimile is made in step (16-1), and then the CNG tone is sent in step (4-1). As in the case of the automatic receiver in the process, the document is transmitted in the process (6-1) while performing the T-30 protocol.

As described above, in the case of manual reception, the document can be delivered correctly only to the user by processing as described above (subscriber number and password input request), thereby retaining the function of document security. In the above description, the financial settlement agency currently using DCP-16 uses the system (DCP-16) in connection with the host computer, and the host computer uses the FAX service of the financial settlement agency. It's not a problem because you sign up automatically and manually when you apply and the host computer remembers the information.

DCP-16 Can display auto / manual when registering DCP-16 subscriber even when using as one system.
