Abstract

본 발명은 전전자 교환기 시스템에 관한 것으로 가입자 선로의 훅상태 검출시 가입자 선로의 잡음으로 인한 에러의 발생을 방지하고 훅상태가 변화한 가입자만을 검출하여 저장하므로 호접속 처리에 부하발생을 배제하도록 한 것이다.The present invention relates to an electronic switching system to prevent the occurrence of an error due to the noise of the subscriber line when detecting the hook state of the subscriber line, and to detect and store only the subscriber that has changed the hook state to exclude the occurrence of load in the call connection process. will be.

본 발명은 가입자보드의 선로에서 발생되는 훅상태 변화를 변화가 발생한 가입자 선로만을 검출저장하여 상위 디바이스에 통보하도록 호접속에 신뢰성이 제공된다.The present invention provides reliability in a call connection to detect and store only a subscriber line having a change in a hook state change occurring at a line of a subscriber board.

Description

전전자 교환기에서 훅상태 검출장치Hook state detection device in electronic switchboard

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 종래의 전전자 교환기에서 섬모리 스캐닝(Summary Scanning) 방식에 의한 훅검출 동작 예시도, 제2도는 본 발명에 따른 전전자 교환기에서 훅상태 검출장치의 구성 블럭도.1 is a diagram illustrating a hook detection operation by a Summon Scanning method in a conventional all-electronic exchange, and FIG. 2 is a block diagram of a hook state detection apparatus of the all-electronic exchange according to the present invention.

Claims (1)

전전자 교환기에 있어서, 전원공급의 초기상태 및 리셋 신호에 의해 초기화 되며 가입자 선로에서 발생되는 훅상태 데이타를 저장하는 제1영역과 상위 디바이스와 인터페이스되고 훅상태가 변화되어 검출된 선로번호 및 가입자 번호를 저장하는 제2영역으로 이루어지는 메모리수단과, 현재 발생되는 가입자 선로의 훅상태 변화데이타와 상기 메모리수단의 제1영역에 저장된 훅상태 데이타를 비교하는 비교수단과, 상기 비교수단으로 비교된 훅상태 데이타가 서로상이할시 칩인에이블 신호와 기록신호를 출력하며 비교된 훅상태 데이타를 래치하는 래치수단 및, 상위 디바이스에서 상기 메모리 수단의 제2영역에 저장된 훅상태 데이타 판독시 동일 어드레스를 양방에서 억세스하는 인터페이스 접속을 중재하는 접속수단을 구비하는 것을 특징으로 하는 전전자 교환기의 훅상태 검출장치.In all electronic switch, line number and subscriber number which are initialized by the initial state of power supply and reset signal and interfaced with the first area and the upper device storing hook state data generated from subscriber line and the hook state is changed. A memory means comprising a second area for storing the data; a comparison means for comparing the hook state change data of the currently generated subscriber line with the hook state data stored in the first area of the memory means; and a hook state compared with the comparison means. Latch means for outputting a chip enable signal and a write signal when data differs from each other, and latching the compared hook state data; and accessing the same address when reading the hook state data stored in the second area of the memory means from an upper device; And connecting means for arbitrating the interface connection. Is a hook state detection device of an electronic switch. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
