Claims (1)

램(30)을 구비한 교환시스템의 통화 이득 제어 방법에 있어서, 통화로를 열어 통화할시 그 회선의 게인을 점검하여 조절해야 하는가 점검하는 제1과정과, 상기 제1과정에서 게인을 조절해야할시 상기 램(30)에서 해당 회선의 레벨값이 저장된 번지를 계산한 뒤 그 번지에서 게인 조절 데이타를 읽어들이는 제2과정과, 상기 제2과정에서 읽어들인 게인 조절데이타만큼 해당 회선의 게인을 조절하는 제3과정으로 구성함을 특징으로 하는 교환시스템의 프로그래머블 이득 조절방법.In the method of controlling a call gain of an exchange system having a RAM 30, a first step of checking whether or not a gain of a line is to be checked and adjusted when a call is opened and a gain must be adjusted in the first step. The second process of reading the gain control data from the address after calculating the address where the level value of the corresponding line is stored in the RAM 30 and the gain of the corresponding line as much as the gain adjusting data read in the second process. Programmable gain control method of the exchange system, characterized in that consisting of a third process to adjust. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
