제1도는 본 발명에 따른 ATM 절환 배열의 실시예를 나타낸다.
Claims (3)
- 셀 헤더가 제공되어 있는 데이터 셀들에 내장된 디지털 데이터를 절환하는 전기통신 절환 배열로서, 상기 배열이 스위치의 입력 선로(1-1:1-n)에서 스위치의 출력 선로까지 셀들을 절환하는 크로스포인트 스위치를 포함하고, 상기 스위치에는 절환될 셀들을 저장하는 셀 버퍼 메모리가 제공되어 있는 사익 전기 통신 절환 배열에 있어서, 상기 셀 버퍼 메모리는 한 영역이 저손실 영역으로 다른 영역이 저지연 영역으로 지칭되는 적어도 2개의 메모리 영역들로 구성되고, 상기 크로스포인트 스위치에는 셀 헤더의 소정 비트값을 판단하는 평가 회로가 제공되고, 상기 평가 회로는 상기 판단된 값에 따라 평가 출력 신호를 발생하고, 사기 크로스포인트 스위치에는 상기 평가 출력 신호를 수신하여 상기 평가 출력 신호의 값에 따라 인입 셀들을 저손실영역으로 또는 저지연 영역으로 할당하는 할당수단이 제공되어 있음을 특징으로 하는 상기 전기통신 절환 배열.
- 제1항에 있어서, 상기 셀 버퍼 메모리로부터 셀들을 판독하는 판독 수단이 설치되어 있고, 이 판독 수단은 상기 저손실 영역의 셀들수를 감지하고 이 셀 수가 소정의 한계값을 초과하면 절환하여 상기 저손실 영역으로부터 셀들을 읽도록 배열되는 상기 전기 통신 절환 배열.
- ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
