본 발명은 국선 교환장치에 관한 것으로, 특히 국선을 구내 교환장치에 가입된 각 가입자내선에 자동으로 연결시켜 통화하게 한 국선자동 교환장치에 관한 것이다. 종래 구내 교환장치에 있어서는 국선신호가 입력될 때, 국선 교환부에서 교환원이 받아 통화한후 그 국선을 송화자가 원하는 구내 가입자의 내선과 연결시켜 통화하게 하였다. 그러나 이와같은 구내 교환장치는 교환원의 업무가 매우많고, 내선수가 많을수록 그에 비례하여 많은 교환원을 필요로 할 뿐만 아니라, 교환원의 퇴근후에는 송화자가 구내의 내선 가입자와 통화할 수 없는 결합이 있었다.The present invention relates to a trunk line exchange system, and more particularly, to a trunk line automatic exchange device which automatically connects a trunk line to each subscriber station subscribed to a premises exchange unit to make a call. In the conventional premises exchange apparatus, when a CO line signal is input, the operator receives a call at the CO line exchange unit, and then connects the CO line with the extension of the subscriber in the desired premises. However, such on-site exchange device has a lot of operator's work, and the more players, the more the operator needs to be proportionately, and after the operator's leave, the caller cannot talk to the extension subscriber in the premises. There was this.

본 발명은 상기의 결합을 제거하기 위하여, 국선의 가입자가 국선번호를 다이얼링한후 구내의 내선가입자번호를 다이얼링하면 국선과 구내의 내선이 자동으로 연결되어 국선 및 내선 가입자가 통화할 수 있게 창안한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In order to eliminate the above combination, the subscriber of the CO line dials the extension number of the premises and then dials the extension number of the premises, and the CO line and the extension of the premises are automatically connected so that the CO line and the extension subscriber can make a call. When described in detail by the accompanying drawings as follows.

제1도는 본 발명 교환장치의 블록도로서, 이에 도시한 바와같이 국선교환부(1) 및 내선 연결부(2)로된 구내 교환장치에 있어서,국선신호가 입력될때 이에 자동응답하여 교환장치가 국선신호를 수신할 수 있게 하는 응답부(3)와, 이 응답부(3)가 자동 응답함에 따라 마이크로프로세서(4)의 제어로 안내방송문을 출력시켜 버퍼(6)를 통해 국선으로 출력시키는 음성합성부(5)와, 국선으로부터 재차 입력되는 다이얼링 신호를 검출하여 마이크로프로세서(4)가 상기 국선교환부(1) 및 내선 연결부(2)를 제어하게 하는 검출부(7)로 구성한 것으로, 상기의 검출부(7)를 제2도의 블록도로 보다 상세히 설명하면 다음과 같다. 국선을 버퍼(9)를 통해서는 마이크로프로세서(4)의 입력단자(IN1)에 접속함과 아울러 그 국선을 스위칭 및 버퍼(10), 펄스카운터(11), 디코더(12)를 통해서는 마이크로프로세서(4)의 입력포오트(D0-D7)에 접속하고, 이 마이크로프로세서(4)의 제어신호단자(S1), (S2)를 상기 스위칭 및 버퍼(10)의 제어단자(ST1) 및 카운터(11)의 제어단자(ST2)에 각기 접속하여 구성한 것으로, 제1도의 도면중 미설명부호 8은 디코더이다. 이와같이 구성된 본 발명의 작용효과를 본 발명의 동작흐름도인 제3도를 참조하여 상세히 설명하면 다음과 같다.1 is a block diagram of the exchange device of the present invention, in the premises exchange device comprising the trunk line exchange unit 1 and the station connection unit 2, as shown therein, when the trunk line signal is input, the exchange device automatically responds to the trunk line exchange. A response unit 3 capable of receiving a signal and a voice synthesis outputting the announcement broadcast under the control of the microprocessor 4 as the response unit 3 automatically responds to the trunk line through the buffer 6. And a detecting section (7) for detecting the dialing signal input again from the trunk line and allowing the microprocessor (4) to control the trunk line switching section (1) and the station connecting section (2). Referring to (7) in more detail the block diagram of Figure 2 as follows. The trunk line is connected to the input terminal IN1 of the microprocessor 4 through the buffer 9, and the trunk line is connected to the microprocessor through the switching and buffer 10, the pulse counter 11, and the decoder 12. (4) is connected to the input ports D0-D7, and the control signal terminals S1 and S2 of the microprocessor 4 are connected to the control terminal ST1 and the counter of the switching and buffer 10 11 is connected to the control terminal ST2, and reference numeral 8 in the drawing of FIG. 1 is a decoder. When described in detail with reference to Figure 3 which is the operation flow diagram of the present invention the effect of the present invention configured as described above.

국선으로부터 신호음이 입력되면, 응답부(3)는 이 신호음을 검출하여 교환장치가 국선신호를 수신할 수 있도록 마이크로프로세서(4)에 응답 완료신호를 출력하고, 이에따라 마이크로프로세서(4)는 음성합성부(5)를 제어하여 음성합성부(5)가 버퍼(6)를 통해 국선으로 안내방송문을 출력하게 한다. 일예로, "안녕사십니까? XXX회사입니다. 교환망을 통해 통화를 하고 싶으시면 XXXX번을 다이얼링 하시고, 그렇지 않으시면 내선 가입자번호를 다이얼링 하십시요"와 같은 안내방송문을 출력한다. 이와같은 상태에서 송화자가 안내방송을 듣고 원하는 구내가입자의 내선번호를 다이얼링하면, 그 내선번호에 대한 다이얼 펄스가 버퍼(9)를 통해 마이크로프로세서(4)의 입력단자(IN)에 인가되고, 이에따라 그 마이크로프로세서(4)는 그의 제어신호단자(S1), (S2)로 제어신호를 출력시켜 스위칭 및 버퍼(10)와 펄스카운터(11)를 동작시키게 된다. 따라서, 이때 송화자가 다이얼링한 내선번화에 대한 다이얼펄스가 스위칭 및 버퍼(10)를 통하고, 펄스 카운터(11)에서 카운트된 후 디코더(12)에서 내선번호에 대한 데이타로 디코딩되어 마이크로프로세서(4)의 입력포오트(D0-D7)에 입력된다. 이에따라 마이크로프로세서(4)는 송화자가 통화하고자 하는 내선가입자의 번호를 인식히고, 그 인식에 따른 제어신호를 디코더(8)를 통해 내선 연결부(2)에 출력함으로써 그 국선과 그 내선가입자의 내선이 연결되어 송화자 및 내선가입자간에 통화가 이루어진다.When a beep is input from the trunk line, the response unit 3 detects the beep and outputs a response completion signal to the microprocessor 4 so that the exchange apparatus can receive the trunk line signal. Accordingly, the microprocessor 4 synthesizes a voice. The control unit 5 controls the voice synthesis unit 5 to output the announcement broadcast to the trunk line through the buffer 6. For example, the message "Hello, I'm XXX company. If you want to make a call through the exchange network, dial XXXX. If not, dial the extension number." In this state, when the caller hears the announcement and dials the extension number of the desired subscriber, the dial pulse for the extension number is applied to the input terminal IN of the microprocessor 4 through the buffer 9, and accordingly. The microprocessor 4 outputs a control signal to its control signal terminals S1 and S2 to operate the switching and buffer 10 and the pulse counter 11. Therefore, at this time, the dial pulse for the extension number dialed by the caller is switched and buffered through the buffer 10, counted by the pulse counter 11, and then decoded by the decoder 12 into the data for the extension number and the microprocessor 4 ) Is input to the input port (D0-D7). Accordingly, the microprocessor 4 recognizes the number of the extension subscriber whom the caller wants to talk to, and outputs the control signal according to the recognition to the extension connection unit 2 through the decoder 8 so that the extension of the trunk line and the extension subscriber thereof is reduced. The call is made between the caller and the subscriber.

한편, 송화자가 내선가입자의 내선번호를 몰라 교환원을 통해 내선가입자와 통화하기 위해 안내방송에 따른 번호를 다이얼링하면, 마이크로프로세서(4)가 국선교환부(1)를 제어하여 국선을 교환원과 연결시키고, 이에따라 교환원에 의해 국선이 송화자의 의뢰에 따른 내선가입자와 연결되어 송화자와 내선가입자 사이에 통화가 이루어진다. 이상에서 상세히 설명한 바와같이 본 발명은 국선을 자동으로 구내 가입자에게 연결시켜 주므로 교환원의 업무량을 줄일 수 있을 뿐만 아니라, 내선가입자의 확장에 따른 인건비를 줄일 수 있는 효과가 있다.On the other hand, when the caller does not know the extension number of the extension subscriber and dials the number according to the announcement to communicate with the subscriber through the operator, the microprocessor 4 controls the trunk line exchange unit 1 to exchange the trunk line with the operator. The CO line is connected to an extension subscriber according to the caller's request by the operator, so that a call is made between the caller and the subscriber. As described in detail above, the present invention automatically connects the trunk line to the subscriber in the premises, thereby reducing the workload of the operator and reducing the labor cost according to the extension of the subscriber.
