Abstract

본 발명은 공통선 신호방식(CCS No.7) 메세지 전달부(MTP)의 레벨 1 및 레벨 2 기능 구현을 위한 신호 단말보드에 관한 것이다.The present invention relates to a signal terminal board for implementing level 1 and level 2 functions of a common line signaling system (CCS No. 7) message transfer unit (MTP).

본 발명은 신호단말보드와 교환기간의 신호채널 연결은 8개의 중계선계를 관리하는 스위치계에 속한 SWCD(Switch complex Device)와 연결하여 신호단말과 SWCD 사이는 서브하이웨이(2Mbps)를 통해 연결되고 SWCD내에서는 스위치 통로(path)를 통해 중계선계로 신호채널이 연결됨으로 시스템 관리체계가 집중화되도록 하였으며, 신호단말모드가 신호채널을 변경할 수 있도록 하기 위하여 보드동작 초기에는 하드웨어적으로 선택하고 보드가 동작중에는 상위레벨로부터 신호채널을 변경하라는 요구를 받으면 프로그램 제어로 신호채널을 변경하여 선택할 수 있도록 구성되었다.The present invention is connected to the signal terminal board and the signal channel of the exchange period is connected to the switch complex device (SWCD) belonging to the switch system that manages the eight relay system connected between the signal terminal and the SWCD via a sub-highway (2Mbps) and In order to enable the signal management mode to be changed, the system management system is centralized by connecting the signal channel to the relay line through the switch path. When requested to change the signal channel from the upper level, it is configured to change and select the signal channel by program control.
