Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

통신선로가 물리적으로 별개의 회선으로 이중화되어 있는 통신망에서 LAP-D 프로토콜로 서로 통신할 시 이중화하는 기술이다.It is a technology to duplicate communication lines when they communicate with each other using LAP-D protocol in a communication network where communication lines are physically separated from each other by a separate line.

2. 발명이 해결하고자 하는 기술적 과제2. Technical Problems to be Solved by the Invention

대용량 전전자교환기에서 교환기본체와 가입자모듈간의 직렬통신을 할 시 이중화한다.In a large capacity electronic exchange, redundancy is required when serial communication is performed between the exchange body and the subscriber module.

3. 발명의 해결방법의 요지3. The point of the solution of the invention

LAP-D방식을 사용하는 데이타 통신시스템에서 데이타 통신을 위한 링크를 이중화하여 두 링크 중 한 링크에 장애발생시 다른 링크로 메세지를 처리한다.In a data communication system using the LAP-D scheme, a link for data communication is duplicated, and when one of the links fails, the message is processed by another link.

4. 발명의 중요한 용도4. Important Uses of the Invention

전전자교환기에서 직렬통신방식을 사용하여 이중화하는 장치에 적용한다.It is applied to a device that uses a serial communication method in an electronic exchanger to duplicate.
