제1도는 본 발명에 따른 교환기의 양호한 실시예, 제2도는 본 발명의 교환기에 대한 출력유닛을 나타내는 블록도, 제3도는 제2도의 출력유닛에 포함된 버퍼의 구성도.

Claims (4)

  1. 경로정보를 사용하여 셀헤더를 각각 포함하고 있는 ATM 셀을 교환할 수 있는 카피 능력을 구비한 ATM교환기에 있어서, 여러단에 배치된 복수의 스위칭 소자를 포함하며 각 입력과 각 출력 사이에서 복수의 접속방식이 가능한 그룹스위치(10)를 구비하는데, 상기 스위칭 소자는 상기 셀헤더에 포함되어 있는 정보에 의하여, 외부로부터 영향을 받지 않는 알고리즘에 의해 경로 정보가 평가되는 제1어드레스 지정 모드와, 변경 가능한 접속테이블의 도움으로 경로 정보가 평가되며 셀이 카피되어 복수의 경로를 통해 전달되는 제2어드레스 지정 모드로 교환이 가능하며; 그룹스위치(10)와 상기 교환기 각 출력(01,02,…,OL)사이에 설치된 출력유닛(411,412,…,41L)을 구비하는데, 상기 출력유닛의 각각은 상기 그룹 스위치의 동작중단후 상기 출력 유닛을 통해 출력되는 모든 셀들이 기입되며 상기 셀헤더에 포함된 라벨(수열)에 의해 결정된 순서로 셀들을 출력하는 버퍼(1)를 포함하고;교환기의 각 입력(I1,I2,…Ii)에서 엑세스가 가능하며, 다른 출력들에 카피스위치(20)를 위임하는 각 셀에 대한 소정수의 카피를 만들고, 그 출력이 그룹스위치(10)의 입력에 접속되는 카피스위치(20)를 구비하는 것을 특징으로 하는 ATM교환기.
  2. 제1항에 있어서, 상기 교환기의 입력(I1,…,Ii)은 그룹스위치(10)를 통해 카피스위치(20)에 접속되어 있는 것을 특징으로 하는 ATM교환기.
  3. 제1항에 있어서, 카피스위치(20)의 각 출력과 그룹스위치(10)의 관련된 입력간에 삽입되는 출력유닛(431,…,43j)을 추가로 구비하는 것을 특징으로 하는 ATM교환기.
  4. 제1항에 있어서, 교환기의 각 입력(I1,…,Ii)과 그룹스위치(10)간에는 셀의 순서를 식별하는 라벨(수열)이 셀들에 부여되는 입력유닛(311,…,31i)이 추가로 제공되는 것을 특징으로 하는 ATM교환기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
