Abstract
Description
Claims (1)
- 사설교환기 아날로그포트의 송수신 감쇄량 측정방법에 있어서, 사설교환기로부터 공급된 프레임 신호와 동기신호를 측정기준용 PCM 데이타로 변환하여 상기 사설교환기 측으로 공급하는 경우 상기 사설교환기 아날로그 포트를 통해 출력되는 신호의 레벨을 측정하여 상기 사설교환기 아날로그 포트의 수신 감쇄량을 측정하고, 측정기준용 아날로그 신호를 상기 사설교환기 측으로 공급하고 상기 사설교환기가 상기 측정기준용 아날로그 신호를 PCM데이타로 변환하여 출력하면 이 출력된 PCM데이타를 측정하여 상기 사설교환기 아날로그 포트의 송신 감쇄량을 측정하는 것을 특징으로 하는 사설교환기 아날로그 포트의 송수신 감쇄량 측정방법.
