Description

How to transfer a fax

TECHNICAL FIELD The present invention relates to a telephone apparatus, and more particularly, to a call transfer method.

In general, the call transfer function provided by a key phone system is a function of connecting a user of a specific extension phone with a partner station on a call with another extension phone. This function could not be used in a small office or home without a keyphone system. As a result, a small office or home user was told to answer a call directly to another user.

For example, if there is a telephone in each room in a two-room home, a call comes from outside and a specific user in a specific room answers the call. However, when the other side of the call requires a call with another user in another room, the specific user has to go to another room and have to deliver the call directly to another user.

Accordingly, in the related art, the wireless telephone system is equipped with an internal call function to solve the above-mentioned troublesome points, but this is also a useless function unless the wireless telephone system is provided.

As described above, the call transfer function could not be used unless an expensive key phone system or a wireless telephone system was provided. As a result, when a user wants to return a call to another user in a small office or home, it is cumbersome that the specific user has to tell the user to answer the call directly.

Accordingly, an object of the present invention is to provide a method of transferring a facsimile to a facsimile in a telephone connected in parallel with the facsimile in an office or a home having a facsimile.

The present invention for achieving the above object is a call transfer command step for searching whether the user of the telephone inputs a transfer digit in the state that the telephone and the external telephone line connected in parallel with the body of the facsimile; After the transfer digit is input, when the telephone is hooked-off, a pseudo-ringing step of waiting for the external telephone line and ringing a facsimile body in the facsimile body; and when the main body is hooked-off in response to the pseudo ringing And a transfer step of connecting the external telephone line with the main body.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 shows a block diagram of a conventional facsimile, where the CPU 10 controls the overall operation of the facsimile according to a preset control program. The modem 12 modulates data in the transmission mode in the transmission mode under the control of the CPU 10, and demodulates the data in the reception mode. The Network Control Unit (NCU) 14 forms a transmission and reception path between the telephone line and the modem 12 under the control of the CPU 10. The DTMF signal detection unit 16 retrieves the DTMF signal transmitted by the parallel telephone 24 and provides it to the central processing unit 10. The hook detection unit 18 detects whether the parallel telephone 22 is hooked-on or hooked-off and provides it to the central processing unit 10. The ring detection unit 20 detects a ring signal provided from the exchanger and provides the ring signal to the central processing unit 10. The hand-set 22 is attached to the facsimile, and the parallel telephone 24 may be installed in a location separate from the facsimile.

The printer 26 then prints an image on a sheet of paper under the control of the central processing unit 10. The memory 28 includes a program memory for storing a program and a data memory for temporarily storing data generated during the execution of the program. The scanner 30 scans an original under the control of the central processing unit 10. The operation panel 32 includes a plurality of keys and a display device for interfacing between the user and the central processing unit 10. The sensor unit 34 senses various states of the facsimile, and provides the sensing data to the central processing unit 10 accordingly. The speaker SPK outputs sound under the control of the central processing unit 10.

2 is a flow chart of a fax transfer method according to a preferred embodiment of the present invention. In step 36 of FIG. 2, the central processing unit 10 searches whether the ring detection unit 20 detects a ring signal provided by the exchange. At this time, if the ring signal is detected, the CPU 10 performs step (40), otherwise performs step (38). In step 38, the CPU 10 performs a corresponding operation. In step 40, the central processing unit 10 rings a facsimile in response to the ring signal. The central processing unit 10 provides a ring signal to the parallel telephone 24. The parallel telephone 24 rings in response to the ring signal.

Here, the facsimile can be hooked-off automatically or by a user's operation as the ring is ringed. The user of the parallel telephone 24 can also hook-off by lifting a handset (not shown) of the parallel telephone 24. Here, the hook-off of the parallel telephone 24 is detected by the hook detector 18.

The CPU 10 performs step 42 while ringing the ring. In step (42), the central processing unit 10 searches whether the facsimile or parallel telephone 24 is hooked off. At this time, the central processing unit 10 performs the step (44) if the fax or parallel telephone 24 is hooked off, otherwise it continues to ring.

In step (44), the central processing unit 10 performs a call service by connecting the hand-set and the other side when the user picks up the hand-set 22 and hooks it off. In addition, the central processing unit 10 performs a fax service when the fax is set to the automatic reception mode or when the user hooks off the fax in order to receive the fax message. The central processing unit 10 connects the parallel telephone 24 and the other side when the parallel telephone 24 is hooked off. As the parallel phone 24 and the other side are connected, the user using the parallel phone can talk with the other side.

In particular, the central processing unit 10 performs step 46 while the user who uses the parallel telephone 24 is talking to the other party through the parallel telephone 24. In step 46, the central processing unit 10 searches whether the DTMF signal is detected as the user of the parallel telephone 24 inputs a DTMF digit. At this time, if the DTMF signal is detected, the CPU 10 performs step 48, otherwise proceeds to step 44 above.

In step 48, the CPU 10 searches whether the DTMF signal is the same as the call transfer DTMF signal set in advance. At this time, the central processing unit 10 performs step 50 if the DTMF signal is the same as the call transfer DTMF signal, and otherwise proceeds to step 44.

In step 50, the central processing unit 10 detects whether it is hooked on. At this time, the central processing unit 10 performs the step 52 when the hook-on, otherwise waits until the hook-on again.

In step 52, the central processing unit 10 waits for an external telephone line, and then proceeds to step 54. In step 54, the CPU 10 generates a pseudoring signal. According to the pseudo signal, a pseudo ring sounds in the facsimile body and the parallel telephone 24. After generating the pseudo signal, the CPU 10 performs step 56. In step 56, the central processing unit 10 searches whether the facsimile body and the parallel telephone 24 are hooked off. At this time, the central processing unit 10 performs step (58) when any one of the facsimile body and the parallel telephone (24) is hooked off, and otherwise performs step (62). In step (62), the central processing unit (10) detects whether a predetermined time has elapsed, and if a predetermined time has not elapsed, proceeds to step (52) and continues to generate pseudo hook. If not, proceed to step 64 to stop the generation of pseudoring and end.

In step (58), the central processing unit (10) stops the ringing ring as it is hooked-off, and proceeds to step (60) to connect the hooked-off device and the external telephone line in the facsimile body or parallel telephone. To perform a call service.

According to the present invention, when a user who has been making a call through an external telephone line connected to a facsimile machine inputs a call transfer DTMF digit and hooks off, the telephone rings after waiting for the external telephone line. In response to the pseudo call, another user of the facsimile body may make a call through an external telephone line. That is, the present invention can call transfer using a facsimile.

As described above, the present invention has the convenience of being able to transfer to a telephone connected in parallel with the facsimile using the facsimile.
