Abstract

본 발명은 OAM셀 자동처리기능을 갖는 ATM통신장치에 관한 것으로, 프로토콜에 따라 소정의 ATM 셀 간격마다 OAM셀을 전송하도록 상기 ATM셀을 카운트하는 카운터(34)와; 상기 OAM셀을 저장하고 있는 로칼 메모리(31); 전송할 데이타의 어드레스를 저장하고 있는 어드레스큐(33); 상기 OAM셀을 저장하도록 상기 로칼메모리(31)를 제어하고 상기 카운터(34)의 제어에 따라 상기 로칼 메모리(31)에 저장된 OAM셀을 전송하도록 상기 어드레스큐(33)에 OAM셀의 어드레스를 지정하며 상기 카운터(34)를 클리어시킨 후 소정의 카운트값을 로딩시키는 중앙처리장치(32); 상기 어드레스큐(33)에 저장된 어드레스에 따라 상기 로칼 메모리(31)의 데이타를 읽어와 광신호로 변환하여 출력하는 전송부(35)로 구성되어 상위계층에서 처리하던 OAM셀을 하위계층인 ATM통신 카드에서 직접 처리하므로써 상위계층의 오버헤드를 줄여 전체 시스템의 성능을 향상시킬 수 있는 효과가 있다.The present invention relates to an ATM communication apparatus having an automatic OAM cell processing function, comprising: a counter (34) for counting the ATM cell to transmit an OAM cell at predetermined ATM cell intervals according to a protocol; A local memory 31 storing the OAM cell; An address queue 33 that stores an address of data to be transferred; The address of the OAM cell is assigned to the address queue 33 to control the local memory 31 to store the OAM cell and to transmit the OAM cell stored in the local memory 31 under the control of the counter 34. A central processing unit (32) for clearing the counter (34) and loading a predetermined count value; ATM communication, which is an OAM cell processed by an upper layer, is composed of a transmission unit 35 which reads data of the local memory 31, converts the data of the local memory 31 into an optical signal, and outputs the same according to the address stored in the address queue 33. By processing directly on the card, the overhead can be reduced, improving the performance of the entire system.
