Abstract
본 정합장치는 교환기에 있어서 하위프로세서와 텔레포니장치간에 PCM방식을 이용하여 정합처리를 하기 위한 것으로서, 본 장치는 하위프로세서와 텔레포니장치간에 접속되어 텔레포니장치의 전송속도를 고려하여 할당된 채널을 통해 펄스폭변조신호를 전송하기 위한 전송라인; 펄스폭변조방식을 이용하여 하위프로세서와 전송라인간에 정합처리를 하기 위한 제1PCM정합부; 펄스폭변조방식을 이용하여 텔레포니장치와 전송라인간에 정합처리를 하기 위한 제2PCM 정합부를 포함하도록 구성된다.The matching device is used to perform a matching process between a sub-processor and a telephony device in a switching system. The device is connected between a sub-processor and a telephony device, and receives a pulse A transmission line for transmitting a width modulated signal; A first PCM matching unit for performing a matching process between a lower processor and a transmission line using a pulse width modulation scheme; And a second PCM matching unit for performing a matching process between the telephony apparatus and the transmission line using a pulse width modulation method.
Description
