Abstract

본 발명은 동기식 전송장치의 운용자통화 통제회로에 관한 것으로, 코덱(CODEC:61,62), 주통제기(63), 예비통제기(64), 주증폭기(65), 예비증폭기(66), 및 수신 선택기(67)로 구성되어 광전송장치를 단국형 혹은 분기/결합형으로 운용시에 운용방식 및 선로상태에 따라 운용자통신을 통제하므로써 양질의 통신채널을 선택하여 사용할 수 있고, 통신선로에 이상이 발생되면 예비선로로 절체하여 서비스채널의 신뢰성을 향상시킬 수 있는 효과가 있다.The present invention relates to an operator call control circuit of a synchronous transmission device, comprising a codec (61, 62), a main controller (63), a preliminary controller (64), a main amplifier (65), a preamplifier (66), and a receiver. It consists of a selector 67, which controls the operator communication according to the operation method and the line status when operating the optical transmission device in single station type or branch / combination type, so that it is possible to select and use high quality communication channel, and an error occurs in the communication line. In this case, the reliability of the service channel can be improved by switching to a spare line.
