Abstract

R2MFC용 DID인터페이스 회로에 관한 것으로 특히 DC루프(R2)라인에 에러가 발생될 시 국선(C,O)라인에서 에러상태를 감지할 수 있도록 SLIC를 이용하여 공급전원을 차단하도록 제어하는 R2MFC용 DID인터페이스 회로에 관한 것이다.DID interface circuit for R2MFC. In particular, when error occurs on DC loop (R2) line, DID for R2MFC controls to cut off the power supply by using SLIC so that error state can be detected on C.O line. Relates to an interface circuit.

R2MFC용 DID인터페이스 회로에서 DC루프라인에 에러가 발생될시 SLIC를 이용하여 공급전원을 차단하여 국선라인(C,O)에 에러상태를 알림으로서 해당 회선의 고장판단 및 복구시간을 줄여 제품의 신뢰성을 향상시키고 또한 회로의 소형화 및 고직접화 할 수 있다.When error occurs on DC loop line in D2 interface circuit for R2MFC, SLIC is used to cut off the power supply to inform the trunk line (C, O) of the error condition, reducing the fault determination and recovery time of the corresponding line, thereby reducing the reliability of the product. In addition, the circuit can be miniaturized and high-directed.
