Description

음성 녹취 기능이 구비된 디지털 전화기{digital phone for voice recording}Digital phone with voice recording function {digital phone for voice recording}

본 발명은 음성 녹취 기능이 구비된 디지털 전화기에 관한 것이다.The present invention relates to a digital telephone equipped with a voice recording function.

사설 자동 구내 교환기(PABX: Private Automatic Branch eXchange)는 아날로그 전화기가 연결된 경우에는 그 아날로그 전화기와 아날로그 신호를 송수신하고, 디지털 단말기가 연결된 경우에는 그 디지털 전화기와 디지털 신호를 송수신한다. 이때, 필요에 따라 각 단말기를 통해서 처리되는 음성통화 내용을 녹취해야할 필요성이 있을 수 있다.Private Automatic Branch Exchange (PABX) sends and receives analog signals with the analog telephone when the analog telephone is connected, and sends and receives digital signals with the digital telephone when the digital terminal is connected. In this case, it may be necessary to record the voice call content processed through each terminal as necessary.

도 1은 종래의 디지털 라인에서 음성신호를 녹취하기 위한 시스템 구성도이다.1 is a system configuration diagram for recording a voice signal in a conventional digital line.

도 1을 참조하면, 사설 자동 구내 교환기(2)에는 아날로그 전화기(1)도 연결될 수 있고, 디지털 전화기(3)도 연결될 수 있다.Referring to FIG. 1, an analog telephone 1 may be connected to a private automatic branch exchange 2, and a digital telephone 3 may also be connected.

이때, 아날로그 전화기(1)의 경우에는, 아날로그 전화기(1)와 사설 자동 구내 교환기(2)간의 라인에 음성 녹취 장치(미도시)를 연결하면, 아날로그 전화기(1)와 사설 자동 구내 교환기(2)간에 송수신되는 음성신호를 녹취할 수 있다.At this time, in the case of the analog telephone 1, when a voice recording device (not shown) is connected to the line between the analog telephone 1 and the private automatic branch exchanger 2, the analog telephone 1 and the private automatic branch exchanger 2 You can record voice signals transmitted and received between

한편, 디지털 라인을 통하여 디지털 전화기(3)가 연결된 경우에는 직접 디지털 라인으로부터는 음성신호를 녹취할 수 없다. 이에 따라, 디지털 라인에서 음성 신호를 녹취하기 위해서는 D/A 컨버터(4)를 이용하여 디지털 신호를 아날로그 신호로 변환한후 아날로그 녹취장치(5)를 연결하여 음성 신호를 녹취하였다. 이와 같이, 종래에는 디지털 신호를 아날로그 신호로 변환하기 위해서는 D/A 컨버터(4)와 같은 별도의 장비가 필요했다.On the other hand, when the digital telephone 3 is connected via a digital line, voice signals cannot be recorded directly from the digital line. Accordingly, in order to record the audio signal in the digital line, the digital signal is converted into an analog signal using the D / A converter 4, and the analog recording device 5 is connected to record the voice signal. As described above, in order to convert a digital signal into an analog signal, a separate equipment such as the D / A converter 4 is required.

아울러, 이기종 교환기마다 프로토콜이 다르기 때문에 프로토콜에 따라 서로다른 D/A 컨버터가 필요하였다. 이에 따라 교환기에 따른 D/A 컨버터 호완성의 문제가 대두되었다.In addition, since different protocols are different for different types of exchanges, different D / A converters are required according to protocols. As a result, the issue of the D / A converter compatibility with the exchange has been raised.

본 발명은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로, 디지털 라인에서 음성 신호의 녹취를 가능하게 하고 이기종 교환기에 따른 아날로그 신호 변환 호환성 문제를 해결할 수 있는 음성 녹취 기능이 구비된 디지털 전화기를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and provides a digital telephone having a voice recording function that enables recording of a voice signal on a digital line and solves an analog signal conversion compatibility problem according to a heterogeneous exchange. The purpose is.

이때, 음성 녹취용 인터페이스부는, D/A 컨버터와 송수화부의 수화부를 연결하는 2 라인에 병렬 연결될 수 있다.In this case, the voice recording interface unit may be connected in parallel to two lines connecting the D / A converter and the handset of the handset.

또한, 음성 녹취용 인터페이스부는, 음성녹취장치의 연결잭을 꽂기 위한 포트가 구비될 수 있다.In addition, the voice recording interface unit may be provided with a port for plugging the connection jack of the voice recording device.

이하, 첨부된 도면을 참조하여 본 발명을 상세히 알아보자.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 음성 녹취 기능이 구비된 디지털 전화기의 구성 블록도이다. 도 2를 참조하면, 본 발명에 따른 음성 녹취 기능이 구비된 디지털 전화기(100)는 크게 D/A 컨버터(110)와, 음성 녹취용 인터페이스부(120)와, 송수화부(130)로 구성될 수 있다. 도면에서 140은 음성 녹취 장치이다.2 is a block diagram of a digital telephone with a voice recording function according to the present invention. 2, the digital telephone 100 having a voice recording function according to the present invention is largely composed of a D / A converter 110, a voice recording interface unit 120, and a handset 130. Can be. In the figure, 140 is a voice recording device.

D/A 컨버터(110)는 디지털 전화기 내부에 설치되어 송수화부(130)로 음성 신호를 보내기 위해 입력된 디지털 신호를 아날로그 신호로 변환한다.The D / A converter 110 is installed inside the digital telephone and converts the input digital signal into an analog signal to send a voice signal to the handset 130.

송수화부(130)는 D/A 컨버터(110)를 통해 변환된 아날로그 신호를 음성으로 재생하는 수화부(131)와, 사용자의 음성신호를 전기적인 아날로그 신호로 변환시키는 송화부(132)로 이루어진다.The handset 130 includes a handset 131 for reproducing an analog signal converted by the D / A converter 110 into voice, and a talker 132 for converting a user's voice signal into an electrical analog signal.

음성 녹취용 인터페이스부(120)는 D/A 컨버터(110)와 송수화부(130)의 사이에 설치된다. 즉, D/A 컨버터(110)와 송수화부(130)는 송수 4 라인 전선을 통해 서로 연결된다. 따라서, 음성 녹취용 인터페이스부(120)는 그 4라인의 전선에 브릿지로 연결하여 D/A 컨버터(110)와 송수화부(130)간에 송수신되는 음성신호를 녹취하게 된다.The voice recording interface 120 is installed between the D / A converter 110 and the handset 130. That is, the D / A converter 110 and the handset 130 are connected to each other through a four-line transmission line. Accordingly, the voice recording interface unit 120 connects the wires of the four lines with a bridge to record voice signals transmitted and received between the D / A converter 110 and the handset 130.

구체적으로는 D/A 컨버터(110)에서 송수화부(130)로의 연결에서 수화부(131)에 연결되는 2라인에 병렬로 연결되게 할 수 있다.Specifically, in the connection from the D / A converter 110 to the handset 130, it may be connected in parallel to two lines connected to the handset 131.

이는, 전화기의 송수화기에서 수신 라인에는 송수신 신호가 모두 흐르므로 수신 라인을 병렬로 연결하면 송수신 음성 신호를 모두 녹취할 수 있다.This is because, in the handset of the telephone, both transmission and reception signals flow through the reception line, and thus, when the reception lines are connected in parallel, both transmission and reception voice signals can be recorded.

이때, 음성 녹취용 인터페이스부(120)는, 음성 녹취장치(140)의 연결잭을 꽂기 위한 포트(미도시됨)를 구비함으로써, 그 포트에 음성 녹취장치(140)의 연결잭을 꽂아 음성 녹취장치를 연결할 수 도 있다.At this time, the voice recording interface 120 is provided with a port (not shown) for plugging the connection jack of the voice recording device 140, plug the connection jack of the voice recording device 140 into the port to the voice recording device You can also connect.

이와 같이 구성된 디지털 전화기의 동작을 살펴보자.Let's look at the operation of the digital phone configured as described above.

디지털 라인으로부터 디지털 전화기(100)에 디지털 신호가 입력되면, 그 입력된 디지털 신호는 D/A 컨버터(110)에서 아날로그 신호로 변환된다. 변환된 아날로그 신호는 4라인을 통하여 송수화부(130)에 전송되어 수화부(131)에서 음성으로 재생된다.When a digital signal is input to the digital telephone 100 from the digital line, the input digital signal is converted into an analog signal by the D / A converter 110. The converted analog signal is transmitted to the handset 130 through four lines and reproduced by voice in the handset 131.

한편, 송화부(132)를 통하여 사용자의 음성이 입력되면, 그 입력된 음성신호는 송화부(132)에서 아날로그 전기 신호로 변환되어 D/A 컨버터(110)를 통하여 디지털 신호로 변환되어 사설 자동 구내 교환기(2)에 전송된다.On the other hand, when the user's voice is input through the transmitter 132, the input voice signal is converted into an analog electric signal by the transmitter 132 and converted into a digital signal through the D / A converter 110 to be automatically Sent to the premises exchange 2.

이때, 음성 녹취용 인터페이스부(120)가 D/A 컨버터(110)와 송수화부(130)간에 브릿지하여 연결됨에 따라, D/A 컨버터(110)에서 변환되어 송수화부(130)로 흐르는 아날로그 음성신호는 음성 녹취용 인터페이스부(120)로 동일하게 흐르게 된다.In this case, as the voice recording interface 120 is bridged between the D / A converter 110 and the handset 130, the analog voice is converted by the D / A converter 110 and flows to the handset 130. The signal flows equally to the voice recording interface 120.

따라서, 이 음성 녹취용 인터페이스부(120)에 연결된 음성 녹취장치(140)에 아날로그 음성신호가 전달되어 녹취가 된다.Therefore, the analog voice signal is transmitted to the voice recording device 140 connected to the voice recording interface unit 120 to record.

이와 같이 디지털 전화기(100)내에 구비된 D/A 컨버터(110)를 이용하고, 음성 녹취용 인터페이스부(120)를 더 구비함으로써, 디지털 라인에서 아날로그 신호를 얻기 위해 별도의 장비없이, D/A 컨버터(110)를 통해 변환되어 송수화부(130)로 전송되는 음성신호를 녹취하면 된다.In this way, by using the D / A converter 110 provided in the digital telephone 100, and further provided with a voice recording interface unit 120, D / A without additional equipment to obtain an analog signal from the digital line The voice signal converted through the converter 110 and transmitted to the handset 130 may be recorded.

본 발명에 의하면, 음성 신호를 디지털 전화기의 수화부에서 바로 얻을 수 있어 별도의 D/A 컨버터 없이 음성 신호를 녹취할 수 있어 이기종 교환기에도 호환성을 제공할 수 있다.According to the present invention, the voice signal can be obtained directly from the receiver of the digital telephone, so that the voice signal can be recorded without a separate D / A converter, thereby providing compatibility to heterogeneous exchanges.
