Abstract

PURPOSE:To bring an incoming telephone set automatically to hook-on state when the transmission of information is finished for caller side by allowing the caller side telephone set to complete the transmission of information and to recognize a special sequence signal transmitted at line disconnection. CONSTITUTION:A special sequence control section 3 decodes a special sequence forecasting line disconnection transmitted from a caller telephone set before line disconnection after the end of communication and generates a command signal to hook on the own telephone set. The transmission side completes the transmission of information and a handset is put on, then a special sequence signal is transmitted. In receiving the said signal, the special sequence control section 3 recognizes the line disconnection of the opposite side and issues a command to a control section 4. The control section 4 sets the telephone set to the hook-on state by the reception of the said command. Thus, the incoming telephone set is brought automatically into the hook state when the caller side completes the transmission of information, which is impossible in an exchange using a PBX.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a telephone that can be used by connecting to a public line or switched line, and is capable of transmitting a specific sequence signal that is transmitted when the calling side telephone terminates transmission. The present invention relates to a telephone that can receive and decode the call, recognize the disconnection of the calling party, and hook-on on the called party.

(Prior art and problems) Conventionally, this type of telephone has been able to recognize the disconnection of the other party by a change in polarity when it is connected to a public telephone line and does not go through a PBX. In the case of lines, the arrangements for signals when disconnecting vary.
It varies depending on the BX. Therefore, the only way to recognize when the other party has disconnected is through empirical judgment by the caller's ears as a change in the intermittent sound.
o (Means for Solving All Problems) Ninth, the present invention corrects these drawbacks by decoding a certain sequence signal transmitted at the time of disconnection of the calling party's telephone on the receiving party's side so that the other party's The object of the present invention is to provide a telephone equipped with means for recognizing disconnection "f", so that this particular sequence signal can be easily distinguished from other signals.
It is also endowed with special characteristics.

The present invention, which achieves the above objects, has the following configuration.

When a call signal is received from the calling party's telephone, it is set to the receiving state, and when making a call, it generates a call code for the other party based on an instruction signal from the host device, and the received text voice signal is converted into a digital signal. a special sequence control unit that receives and decodes a special sequence signal that foretells line disconnection that is sent by the calling side telephone after communication ends and before the line is disconnected, and generates on the hook-on instruction signal; The telephone includes a control unit that receives a hook-on instruction signal from the unit and sets the hook-on state, an interface control unit that controls the transmission and reception of control signals between the control unit and a host device, and a handset. .

(Function) Hereinafter, the function of the telephone according to the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing the structure of a telephone according to the present invention. 1 is a network controller (Network Con
Trol Unit (NCU) automatically sets its own telephone to a receiving state when called by the other party.When a call is made, a function is performed to issue a calling signal in response to an instruction from a host device. 2 is a percentage converter that converts the received voice analog signal into a digital signal for digital processing in the host device, and 3 is a special sequence control unit that is used to control the transmission rate after the calling side telephone completes communication and before the line is disconnected. It generates a special sequence kmH that foretells the disconnection of the outgoing line, and generates an instruction signal to hook-on the electric packing machine.

4 has a microprocessor and memory and t- with control i;
Interprets and executes instructions from the host device, and also receives hook-on instruction signals from the special sequence control unit.
Set to hook-on state. Reference numeral 5 denotes an interface control unit which controls all transmission and reception of control signals between the control unit 4 and the host device. 6 is used when calling and transmitting a call to the other party using the handset. 7.8 is a switch, and switch 7 is a switch controlled by line controller 1, which is normally connected to contact A and connected to contact B when a call is made from another telephone. In the hook-on state, the switch 8 is connected to the contact A, and when the handset 6 is picked up, it is connected to the 9 o'clock Fi contact B, that is, the end of the handset 6.

Now, in the waiting state, the line controller 1 is connected to the switch 71r.
, and connect it to the far point B side for reception.

The received audio analog signal is converted into a digital signal by the converter 2 and transmitted to the host device. In this state, when the transmitting side finishes transmitting information and hangs up the handset, a special sequence signal is transmitted.By receiving this signal, the special sequence control unit 2 recognizes that the other party's line has been disconnected and controls the Upon receiving this command, the control section 4 sets the telephone to the hook-on state.

FIG. 2 shows a t-communication system using the telephone of the present invention.

10 is a public line that connects the calling side and the called side +! This is a double-crossing, switchable line (PBX).

Reference numeral 9.9' shows a system consisting of a telephone of the present invention connected to a public telephone exchange or switching line (PBX) and various devices connected thereto. 12 is a flea packing machine of the present invention, 13 is a device such as a personal computer or an intelligent terminal, and 14 is a storage device (disk).

Equipment 13 such as pan controllers and intelligent terminals
From there, the connection is confirmed using the R8-232-C interface 7Ace, and the voice is input using the Status Keplogger of the telephone set of the present invention. The receiving side performs AD conversion of the input voice using the image converter in the telephone of the present invention, and creates a voice data file on the disk via the R8-232-C interface.

The caller hangs up the phone when input is complete. At this time, the transmitting side disconnects after completing transmission of a certain sequence signal. By receiving this sequence signal with the special sequence control section of the telephone 12 of the present invention, the receiving side recognizes the completion of transmission tg of the calling side. This is recognized by computers, intelligent terminals, etc. as the status of the call being completed.
Audio file creation H, t-Aborted.

The voice file created in this way can later be used by a personal computer or an intelligent terminal, and if used as an automatic voice entry system, it can be used as a so-called answering machine or the like.

(Effects of the Invention) As stated above, the present invention provides a telephone with a means for recognizing a special sequence of signals that the calling telephone transmits when it completes transmitting information and disconnects the line. When the calling party completes sending the information, which was not possible with conventional PBXs and switched lines, the receiving party's phone is automatically turned off.'2. Off □ has the advantage of □3□1□Ayo, Yo, Oi.
