Abstract

본 발명은 사설교환기의 아날로그 포트에서 송수신 되는 신호의 감쇄량을 측정하는 방식에 관한 것으로, 사설교환기의 아날로그 포트에 대한 신호레벨 측정을 디지탈 기준점을 가지고 측정함으로서 송수신 신호의 감쇄량 측정을 정확하고 신뢰성 있게 측정 하도록 한 사설교환기 아날로그 포트의 송수신 감쇄량 측정방법에 관한 것이다.The present invention relates to a method for measuring the attenuation of the signal transmitted and received at the analog port of the private exchange, and to measure the attenuation of the transmitted and received signal accurately and reliably by measuring the signal level of the analog port of the private exchange with a digital reference point. It relates to a method for measuring the amount of transmission and reception attenuation of a private exchange analog port.

본 발명은 일정한 디지탈 신호를 기준 데이타로 하여 사설교환기의 아날로그 포트에 대한 송수신 감쇄량측정을 하므로, 피측정 아날로그 포트에 대한 신호감쇄량 측정을 정확하고 신뢰성 있게 할 수 있다.According to the present invention, since the transmission / reception attenuation of the analog port of the private exchange is measured using a constant digital signal as reference data, the signal attenuation of the analog port to be measured can be accurately and reliably.

Claims (1)

사설교환기 아날로그포트의 송수신 감쇄량 측정방법에 있어서, 사설교환기로부터 공급된 프레임 신호와동기신호를 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 아날로그신호를 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.In the method for measuring the transmission / reception attenuation of the analog exchange port, the level of the signal output through the analog exchange port is converted when the frame signal and the synchronous signal supplied from the private exchange are converted to the measurement reference PCM data and supplied to the private exchange side. Measure the received attenuation of the analog exchange analog port, and supply the measurement standard analog signal to the private exchange side, and when the private exchange converts the analog signal for measurement standard to PCM data and outputs the measured PCM data, Transmitting / receiving attenuation amount measurement method of the analog exchange analog port. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
