Abstract

PURPOSE: A wiretapping apparatus of an exchange is provided to prevent a noise from being generated in a wiretapped content by wiretapping a call between subscribers through a receiving terminal from a time switch that makes a PCM communication, that is a digital communication, with the first, the second and the third analog subscriber board by being respectively connected with a sub-highway cable. CONSTITUTION: Analog subscriber phones respectively connected to the first and the second analog subscriber board(22,24) are put to a call state through a time switch(26). The first, the second and the third analog subscriber board(22,24,28) are connected to the time switch(26) through a sub-highway cable to make a PCM communication, that is, a digital communication. An operator wiretaps a call between subscribers by an operator phone set through a receiving terminal of the time switch(26) and the third analog subscriber board(28). Only the receiving terminal of the time switch(26) is connected between the third analog subscriber board(28) and the time switch(26) while a transmitting terminal is not connected thereto, so that the voice of the operator may not be transmitted to the subscriber phone set.

본 발명은 교환기의 감청 장치에 관한 것으로, 특히, 가입자 전화기간을 교환하는 시분할 스위치(Time Switch : TSW)에서 수신 라인을 통해 감청하는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tapping apparatus of an exchange, and more particularly, to an apparatus for tapping through a receiving line in a time switch (TSW) for exchanging subscriber telephone periods.

이와 같은 본 발명은 TDX-100 이라는 전전자 교환기(full electronic switching system) 외에 다른 기종의 교환기에서도 사용이 가능하다.The present invention can be used in other types of exchangers in addition to the full electronic switching system called TDX-100.

도 1은 종래 교환기의 감청 장치의 일 실시 예를 나타낸 블록도로, 제 1, 제 2 아날로그 가입자 보드(2, 4), 제 1, 제 2 시분할 스위치(6, 18), 인-테스트 버스(in-test bus)(8), 아웃-테스트 버스(out-test bus)(10), 및 아날로그 시험 장치(12)로 구성된다. 상기 아날로그 시험 장치(12)는 채널 0(14) 및 채널 1(16)을 구비한다.1 is a block diagram showing an embodiment of a tapping apparatus of a conventional exchange, including first and second analog subscriber boards 2 and 4, first and second time division switches 6 and 18, and an in-test bus (in -test bus (8), out-test bus (10), and analog test device (12). The analog test apparatus 12 has a channel 0 (14) and a channel 1 (16).

동 도면에 있어서, 제 1, 제 2 아날로그 가입자 보드(2, 4)에 각기 연결된 가입자 전화기를 사용하는 각 가입자는 제 1 시분할 스위치(6)를 통해 서로 통화한다.In the figure, each subscriber using the subscriber telephones respectively connected to the first and second analog subscriber boards 2, 4 communicates with each other via the first time division switch 6.

아날로그 시험 장치(12) 내의 채널 1(16)은 인-테스트 버스(9) 및 아웃-테스트 버스(10)를 통해 제 2 아날로그 가입자 보드(4)의 가입자 라인에 연결되어 가입자간의 음성 신호를 운영자 전화기로 제 2 시분할 스위치(18) 및 채널 0(14)을 통해 제공하여 운영자가 상기 가입자간의 통화를 감청할 수 있도록 한다.Channel 1 16 in analog test device 12 is connected to the subscriber line of second analog subscriber board 4 via in-test bus 9 and out-test bus 10 to operate voice signals between subscribers. Provided to the telephone via a second time division switch 18 and channel 0 14 to enable the operator to intercept the call between the subscribers.

따라서, 통화 중에 아날로그 가입자 보드의 가입자 라인에 정합하여 착, 발신자의 통화를 감청하기 때문에, 이 가입자 라인에 발생하는 잡음에 의해 감청의 질이 저하된다. 즉, 아날로그 가입자 라인에는 잡음이 섞이기가 쉽다.Therefore, the interception of the caller's call is intercepted by matching with the subscriber line of the analog subscriber board during the call, so that the quality of interception is degraded by the noise generated in the subscriber line. In other words, noise is likely to mix in analog subscriber lines.

따라서, 본 발명은 이와 같은 종래 기술의 결점을 해결하기 위하여 안출한 것으로, 다수의 아날로그 가입자 보드와 각기 서브하이웨이 케이블(subhighway cable)로 연결되어 PCM(Pulse Code Modulation, 펄스 부호 변조) 통신하는 시분할 스위치로부터 수신 단을 통해 가입자간의 통화를 감청하도록 하는 교환기의 감청 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the drawbacks of the prior art, a time-division switch that is connected to a plurality of analog subscriber boards and each subhighway cable (Pulse Code Modulation, PCM) communication It is an object of the present invention to provide a tapping device of an exchange to tap a call between subscribers through a receiving end.

상기 목적을 달성하기 위한 본 발명은, 다수의 아날로그 가입자 정합부와 각기 서브하이웨이 케이블로 연결되어 디지털 통신하는 시분할 스위치를 구비하는 교환기에 있어서: 상기 시분할 스위치로부터 수신 단을 통해 정합하는 감청용 아날로그 가입자 정합부; 상기 감청용 아날로그 가입자 정합부와 접속하여 가입자간 통화를 감청하는 운영자 전화기를 포함하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a switch comprising: a plurality of analog subscriber matching units and a time division switch connected to each of the sub-highway cables for digital communication: an analog subscriber for eavesdropping matching from the time division switch through a receiving end. Matching part; It is characterized in that it comprises an operator telephone connected to the interrogation analog subscriber matching unit for intercepting the call between subscribers.

26 : 시분할 스위치26: time division switch

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 대하여 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 교환기의 감청 장치의 일 실시 예를 나타낸 블록도로, 제 1, 제 2, 제 3 아날로그 가입자 보드(22, 24, 28) 및 시분할 스위치(26)로 구성된다.FIG. 2 is a block diagram showing an embodiment of a tapping apparatus of an exchange according to the present invention, and includes first, second and third analog subscriber boards 22, 24 and 28 and a time division switch 26. As shown in FIG.

동 도면에 있어서, 제 1, 제 2 아날로그 가입자 보드(22, 24)에 각기 연결된 아날로그 가입자 전화기간을 시분할 스위치(26)를 통해 통화 상태로 만든다. 상기 제 1, 제 2, 제 3 아날로그 가입자 보드(22, 24, 28)와 시분할 스위치(26)간은 서브하이웨이 케이블을 통해 연결되어 PCM 통신 즉, 디지털 통신한다.In the figure, the analog subscriber telephone periods respectively connected to the first and second analog subscriber boards 22 and 24 are brought into a call state through the time division switch 26. The first, second, and third analog subscriber boards 22, 24, and 28 and the time division switch 26 are connected through a subhighway cable to perform PCM communication, that is, digital communication.

운영자는 운영자 전화기를 통해 가입자간의 통화를 시분할 스위치(26)의 수신 단 및 제 3 아날로그 가입자 보드(28)를 통해 감청한다. 상기 제 3 아날로그 가입자 보드(28)와 시분할 스위치(26)간에는 시분할 스위치(26)의 수신 단만 연결되고 송신 단은 연결되지 않도록 하여 운영자의 음성이 가입자 전화기로 전송되지 않도록 한다.The operator intercepts the call between subscribers via the operator telephone through the receiving end of the time division switch 26 and the third analog subscriber board 28. Only the receiving end of the time division switch 26 is connected between the third analog subscriber board 28 and the time division switch 26, and the transmitting end is not connected so that the operator's voice is not transmitted to the subscriber telephone.

이상에서 설명한 바와 같이, 본 발명은 제 1, 제 2, 제 3 아날로그 가입자보드(22, 24, 28)와 각기 서브하이웨이 케이블로 연결되어 PCM 통신 즉, 디지털 통신하는 시분할 스위치(26)로부터 수신 단을 통해 가입자간의 통화를 감청하도록 한다. 따라서, 제 1, 제 2, 제 3 아날로그 가입자 보드(22, 24, 28)와 시분할 스위치(26)간은 디지털 통신을 하기 때문에, 감청 내용에 잡음이 발생하지 않는 효과가 있다. 또한, 종래와 같은 아날로그 시험 장치(12)를 별도로 사용할 필요가 없기 때문에, 감청에 사용되는 비용이 절감된다. 즉, 아날로그 가입자 라인에는 잡음이 섞이기가 쉬운 반면, 디지털 가입자 라인으로 사용되는 서브하이웨이 케이블에는 잡음이 전혀 섞이지 않는다.As described above, the present invention is connected to the first, second, and third analog subscriber boards 22, 24, and 28 by a subhighway cable, and is connected to the receiving terminal from the time division switch 26 for PCM communication, that is, digital communication. To intercept the call between subscribers. Therefore, since the digital communication is performed between the first, second, and third analog subscriber boards 22, 24, and 28 and the time division switch 26, there is an effect that noise is not generated in the interception. In addition, since there is no need to separately use the analog test apparatus 12 as in the related art, the cost used for wire tapping is reduced. That is, noise is easy to mix in analog subscriber lines, while noise is not mixed in subhighway cables used as digital subscriber lines.
