Abstract
본 발명은 종합 정보 통신망 소규모 NT 2(NETWORK TERMINATION 2), 또는 NT 12(NETWORK TERMINATION12)의 한 모듈로 종합 정보통망 단말기나 단말어댑터 (TERMINAL ADAPTER)와 직접 접속되어 기본 속도의 종합 정보 통신망 서비스를 가입자에게 제공한 것으로서, 하나의 보드로 되어 있으며, 점대점 구조에서는 8가입자, 점대다점 구조에서는 최대 64가입자 지원할 수 있는 가입자 보드에 관한 것이다. 본 발명은 점대점구조에서는 8대의 단말기를, 점대다점 구조에서는 최대 64대의 단말기를 지원한다. 또한 D채널 통신에는 RS485루프를, B채널 통신에는 PCM 인터페이스를 사용하므로써 본 발명에 의존하는 인터페이스를 지양하고, 호환성이 높은, 일반적으로 권고된 인터페이스를 사용하였다.The present invention is a module of small-scale NT 2 (NETWORK TERMINATION 2) or NT 12 (NETWORK TERMINATION 12) of the integrated telecommunication network directly connected to the integrated telecommunications terminal or terminal adapter (TERMINAL ADAPTER) subscribers to the basic speed integrated telecommunications service As provided to the, it is a single board, and relates to a subscriber board that can support up to 64 subscribers in the point-to-point structure, and up to 64 subscribers in the point-to-multipoint structure. The present invention supports 8 terminals in the point-to-point structure and up to 64 terminals in the point-to-multipoint structure. In addition, by using the RS485 loop for the D-channel communication and the PCM interface for the B-channel communication, the interface relying on the present invention is avoided, and a highly compatible and generally recommended interface is used.
