Abstract

종합정보통신망(ISDN)의 사용자-망 접속에서의 LAPD 구현방법에서, 프로토콜 프로그램을 컴파일링 링킹로딩 롬 수록절차에 의해 롬에 저장하고, 상기 롬에 저장된 프로토콜 프로그램을 CPU에 수행하고, RAM를 통하여 LAPD와 각 계층간에 프리미티브를 전달시킬 때, 우선적으로 이벤트를 구분한 후, LAPD의 현재 스테이트를 처리함으로써, 처리절차의 중복을 피하고, 처리시간을 단축할 수 있다.In a method of implementing LAPD in a user-network connection of an integrated information communication network (ISDN), a protocol program is stored in a ROM by a compilation linking loading ROM storing procedure, a protocol program stored in the ROM is executed in a CPU, and the RAM is When passing primitives between the LAPD and each layer, the events are first classified, and the current state of the LAPD is processed, thereby avoiding duplication of processing procedures and reducing processing time.
