Abstract
Description
Claims (1)
- 동기식 다중 계위(SDH)의 네트워크 노드 인터페이스(NNI)신호인 STM-4(Synchronous Transport Module-4) 신호를 처리하는 장치에 있어서, 광으로 입력되는 STM-4 신호를 전기적 신호를 변환시키는 광수신 수단(U8) ; 상기 광수신 수단에 연결되어 있으며, 전기적 신호로 변환된 STM-1 신호로 부터 클럭을 추출하는 수신클럭 추출 수단(U9) ; 상기 광수신 수단 및 수신클럭 추출 수단에 연결되어 있으며, 상기 광 수신 수단에서 입력되는 수신 STM-4 프레임과 수신클럭 출력수단에서 입력되는 수신클럭을 입력으로 하여 프레임 동기를 시킨 후, 스프램블링하여 원래 STM-4 프레임을 복구하고, MSOH(Multiplexer Section Over Heard) 및 RSOH(Regenerator Section Over Head)를 추출하여 처리하며, 오버헤드를 처리하고 나서, AU32 단위로 스위칭하여 출력하는 디멀티플랙싱 수단(U7) ; 상기 디멀티플랙싱 수단에 연결되어 있으며, 포인터 조정을 통하여 송신 AUG 신호와 수신 AUG 신호의 프레임 정렬을 수행하는 AU 포인터 조정 수단(U6) ; 상기 AU 포인터 조정 수단에 연결되어 있으며, HSMB(High Speed Multiplexing Board) 보드를 절체하는 기능을 수행하는 보드절체 수단(U5) ; 상기 AU 포인터 조정 수단 및 보드절체 수단에 연결되어 있으며, 상기 보드절체 수단(U5)에서 출력되는 AUG 신호와 상기 AU 포인터 조정 수단(U6)에서 출력되는 AUG 신호를 입력으로 하여 AUG 신호를 AU32 단위로 분리한 후, 일대일 대응시켜 둘중 하나를 선택하여 출력하는 쓰루/애드(Through/Add) 신호 선택 수단(U4) ; 자신과 연결되어 있는 상기 쓰루/애드신호선택 수단(U4)의 출력과 다른 방향의 STM-4 신호처리기의 쓰루/애드 신호선택 수단의 출력을 입력으로 하여 둘중 하나를 선택하고 한쪽 신호처리기의 출력을 전부 출력하는 쓰루/루프 백 제어 수단(U3) ; 상기 쓰루/루프백 제어 수단에 연결되어 입력되는 AUG 신호를 AU32 단위로 스위칭을 하고, MSOH(Multiplexer Section Over Heard) 및 RSOH(Regenerator Section Over Head)를 삽입한 후, 스크램블링을 하여 스크램 블링된 완전한 STM-4 신호를 출력하는 멀티플랙싱 수단(U2) ; 및 상기 멀티플랙싱 수단에서 최종 형성된 스크램블링된 STM-4 신호를 광으로 변환하여 변환하여 출력하는 광 송신 수단(U1) ; 을 포함하여 구성되는 것을 특징으로 하는 에이유(AU) 단위의 애드/드롭 기능을 수행하는 에스티엠-4 신호처리기.
