Abstract

본 발명은 종합정보통신망(이하, ISDN이라 함) 중용량 망종단장치12(이하, NT12라 함)의 스위칭 제어장치에 관한 것으로, 종래의 기술이 대부분 아날로그나 디지탈 가입자 등으로 구성된 기술로 종합정보통신망의 구성과는 상이하고, 선진국에서도 아직 시범망 운용의 단계에 있는 바 디지탈과 ISDN망을 공용으로 구성하여 구현하고 있으나 구성모듈에서 틀린점이 있으며, ISDN NT12를 위한 가입자, 망 인터페이스로 하여 ISDN 사설 교환기의 기능을 수행하므로서 ISDN 망 구현에 사설 교환기로서의 기초를 마련하였으며 동작에 있어서도 D채널 정보의 처리를 두 보드에 나누어 구현하여 실시간 처리가 이루어지도록 하였으며 B채널 정보도 중계보드를 거쳐 집중화한 후 스위칭을 수행함으로서 여러 가입자로 부터 오는 B 채널 정보의 부하를 효율적으로 처리하도록 구현된 잇점이 있다.The present invention relates to a switching control device of a comprehensive information communication network (hereinafter referred to as ISDN) medium-capacity network termination device 12 (hereinafter referred to as NT12), and the conventional technology is a technology composed mostly of analog or digital subscribers. It is different from the configuration, and developed countries implement both the digital and ISDN networks that are still in the pilot network operation stage, but there is a difference in the configuration module, and ISDN private exchange for subscriber and network interface for ISDN NT12. In order to realize the ISDN network, the foundation was established as a private exchange.In operation, the D-channel information was divided into two boards for real-time processing.The B-channel information was also concentrated through the relay board and switching was performed. To efficiently handle the load of B channel information from multiple subscribers. There is an advantage implemented.
