여기서, ASS는 가입자 및 중계선 정합기, 타임 스위치, 프레임 릴레이 핸들러(Frame Relay Handler), 광 가입자 접속 장치, 각종 신호 장치, 패킷 핸들러 (Packet Handler) 등을 구비하여 대부분의 호처리 기능과 자체 운용 및 유지 보수 기능을 수행하며, 필요시에는 ASS 단위로 증가가 가능하므로 시스템적으로 수평 분산 구조를 가진다.Here, the ASS includes a subscriber and a trunk line matching device, a time switch, a frame relay handler, an optical subscriber access device, various signal devices, and a packet handler, so that most of the call processing functions, It performs the maintenance function and it can increase in ASS unit when necessary, so it has a systematic horizontal dispersion structure.
INS는 ASS 상호간 또는 ASS와 CCS 사이를 연결하는 한편, 번호 번역, 루트 제어, 스페이스 스위치 네트워크의 제어 및 망동기 장치를 구비하여 시스템 클럭을 생성, 배급하는 기능을 수행하는 것으로서, INS와 ASS간에는 광섬유 링크로 연결되어 있으며, 데이터 링크라 부른다.The INS connects the ASSs or the ASSs and the CCSs and performs the function of generating and distributing the system clocks by providing the number translation, the route control, the control of the space switch network, and the network synchronization device. Link, which is called a data link.
CCS는 시스템의 총괄적인 운용 및 유지 보수 기능을 수행하며, 망관리, 시험 및 측정, 과금 통계, 입/출력 장치 제어, 타 시스템과의 대화 기능을 수행하는 장치이다.CCS performs the overall operation and maintenance functions of the system, and is a device that performs network management, test and measurement, billing statistics, input / output device control, and communication with other systems.
이러한 구성의 전전자 교환기에서 ASS는 상술한 바와 같은 가입자 정합기를 구비하며, 가입자 정합기는 가입자 또는 중계선의 상태를 감시하는 기능을 수행하며, 가입자 또는 중계선의 변화에 따라 호처리부로 정보를 보내는 기능을 행한다. 즉, 가입자 정합부는 가입자가 송수화기를 훅킹 온/오프하는 상태를 감지하며, 이 정보를 호처리부로 전달하여 가입자에게 필요한 동작을 행하게 한다.In the former electronic exchanger having such a configuration, the ASS includes a subscriber matching device as described above, and the subscriber matching device monitors the status of the subscriber or trunk line and transmits information to the call processing section according to the change of subscriber or trunk line I do. That is, the subscriber matching unit senses a state in which the subscriber hooks the handset on / off, and transmits the information to the call processing unit to perform operations required by the subscriber.
도 1에는 이러한 기능을 행하는 가입자 정합기의 구성이 도시되어 있다. 도시된 바와 같이 다수의 가입자 라인(A1-An)이 공통 제어 보드(Common Control Board; 이하, CCB라 함)(1)에 연결되어 있으며, 이 CCB(1)는 프로세서(2)의 제어에 따라 가입자 라인(A1-An)의 정보를 TDM처리하여 스위칭 장치(4)에 인가한다. 이와 같이 TDM화되어 스위칭 장치(4)에 인가된 가입자들의 호처리는 별도의 번호 번역기 등을 통하여 행하여지며, 스위칭 장치(4)내의 타임 스위치 및 공간 스위치에서 통화로가 설정되어 가입자들 상호간의 통화로가 형성된다. 이때, 통상의 교환기에서는 스위칭 장치(4)내에 집선 기능을 행하는 집선 장치(DLC)가 형성되어 집선 기능을 행하게 구성되어 있다.Fig. 1 shows a configuration of a subscriber matching device that performs such a function. As shown, a plurality of subscriber lines A1-An are connected to a common control board (CCB) 1, which is controlled by the processor 2 And applies the information on the subscriber's line A1-An to the switching device 4 by TDM processing. The call processing of the subscribers applied to the switching apparatus 4 by the TDM is carried out through a separate number translator or the like, and the call is set in the time switch and the space switch in the switching apparatus 4, Is formed. At this time, in the ordinary exchanger, the concentrator DLC that performs the collecting function in the switching device 4 is formed to perform the collecting function.
그러나, 이와 같은 종래의 가입자 정합 장치는 가입자 라인(A1-An)과 스위칭 장치(4) 사이의 CCB(1)가 고장나는 경우에는 통화로가 절단되어 통화를 행할 수 없다는 문제가 발생한다.However, in such a conventional subscriber matching apparatus, when the CCB 1 between the subscriber line A1-An and the switching device 4 fails, there is a problem that the call is disconnected and the call can not be performed.
또한, 종래의 가입자 정합 장치는 상술한 바와 같이 집선 장치(DLC)가 스위칭 장치(4)내에 구성되므로 스위칭 장치(4)의 단자가 복잡해지는 일원인이 되어 왔다.Further, in the conventional subscriber matching device, as described above, the concentrator DLC is configured in the switching device 4, which causes the terminal of the switching device 4 to become complicated.
본 발명은 이러한 문제를 해결하기 위하여 안출한 것으로서, 본 발명의 목적은, 가입자 정합 장치내의 CCB를 이중화한 전전자 교환기의 가입자 정합 장치를 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and it is an object of the present invention to provide a subscriber matching apparatus of an electronic switching system in which CCBs in a subscriber matching apparatus are duplicated.
본 발명에 따른 전전자 교환기의 가입자 정합 장치는, 프로세서의 제어에 따라 가입자 라인을 통한 정보를 스위칭 장치에 TDM 변환시켜 인가하는 공통 제어 보드(Common Control Board)를 구비하는 전전자 교환기의 가입자 정합 장치에 관한 것으로서, 공통 제어 보드를 가입자 라인 및 프로세서와 스위칭 장치 사이에서 이중화 구성하며, 이 공통 제어 보드내에 집선 장치를 각각 구성한다.A subscriber matching apparatus of an electronic switching system according to the present invention includes a subscriber matching apparatus of a full-duplex switching center having a common control board which applies TDM conversion of information through a subscriber line to a switching apparatus under the control of a processor, In which a common control board is configured to be duplexed between a subscriber line and a processor and a switching device, and each of the concentrators is configured in the common control board.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 대하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 전전자 교환기의 가입자 정합 장치의 블록도로서, 도시된 바와 같이 가입자 라인(A1-An)은 각각 두 개의 CCB(11,12)에 각각 연결되어 있으며, 이 CCB(11,12)들은 프로세서(2),(2-1) 및 스위칭 장치(4)에 각각 연결되어 있다.2, the subscriber line A1-An is connected to two CCBs 11 and 12, respectively, and the CCBs 11 and 12 are connected to the subscriber lines A1- , 12 are connected to the processors 2, 2-1 and the switching device 4, respectively.
즉, CCB(11,12)는 프로세서(2),(2-1)과 함께 이중화된 구성을 가지고 있어, CCB(11 또는 12) 및 프로세서(2),(2-1)은 각각 액티브(Active) 및 스탠바이(Stand By) 상태로 구동한다. 이때, 액티브 상태의 CCB(11 또는 12) 및 프로세서(2 또는 2-1)가 구동중에 이상이 발생한 경우에 스탠 바이 상태로 구동중이었던 CCB(11 또는 12) 및 (2, 2-1)은 액티브로 자동 절환하므로써 가입자 라인(A1-An)과 프로세서(2, 2-1) 및 스위칭 장치(4)와의 통화로는 계속 유지된다.That is, the CCBs 11 and 12 have a dual configuration together with the processors 2 and 2-1, and the CCBs 11 and 12 and the processors 2 and 2-1 are active ) And standby (Stand By) state. At this time, the CCB (11 or 12) and (2, 2-1) that were operating in the standby state when the active CCB (11 or 12) and the processor (2 or 2-1) The active line is maintained in the call between the subscriber line A1-An and the processors 2 and 2-1 and the switching device 4. [
또한, 본 발명의 CCB(11,12)내에는 도시된 바와 같이 집선 장치(D1,D2)가 각각 구성되어 있다. 즉, 본 발명의 CCB(11,12)들은 가입자 라인(A1-An)을 통한 정보를 일차적으로 집선하여 스위칭 장치(4)에 인가하는 것이다. 이때, 스위칭 장치(4)는 종래와 동일하게 내부에 집선 장치가 구성되어 있으므로 본 발명의 전전자 교환기에서는 집선율을 실질적으로 높일 수 있다.In the CCBs 11 and 12 of the present invention, the concentrators D1 and D2 are constituted as shown in the figure. That is, the CCBs 11 and 12 of the present invention primarily collect information on the subscriber lines A1-An and apply them to the switching device 4. [ At this time, since the switching device 4 has a built-in concentrator in the same manner as in the conventional art, the convergence rate can be substantially increased in the entire electronic exchanger of the present invention.
또한, 종래의 전전자 교환기와 동일한 집선율을 유지하는 경우에는 집선 장치(D1,D2)에서 일차적으로 집선된 상태이므로 스위칭 장치(4)의 집선율을 낮출 수 있어 스위칭 장치(4)를 간단히 구성(집선을 위한 입력 단자수를 줄일 수 있다)할 수 있다.In addition, in the case of maintaining the same collecting rate as that of the conventional all-electronic exchanger, since the collecting devices D1 and D2 are collectively arranged, the collecting rate of the switching device 4 can be reduced, (The number of input terminals for collecting can be reduced).
이상 설명한 바와 같이 본 발명에 따르면, 가입자 정합 장치를 이중화하므로써 통화의 안정성을 확보할 수 있으며, 가입자 정합 장치내에 집선 장치를 구성하므로써 스위칭 장치를 간소화할 수 있다는 효과가 있다.As described above, according to the present invention, it is possible to secure the stability of the communication by duplicating the subscriber-mating device, and the switching device can be simplified by constructing the concentrator in the subscriber mating device.
