2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

U인터페이스를 사용하는 가입자 접속단과 교환시스템에 가입자 단말기를 고속으로 접속시켜 가입자 접속단과 교환시스템간의 액티베이션 성능을 향상시킨다.U interface to the subscriber terminal and the switching system at high speed, thereby improving the activation performance between the subscriber access terminal and the switching system.

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

본 발명은 가입자 접속단측과 교환시스템측간의 불필요한 접속과정의 생략, 통합 및 주기적인 가입자측 감시를 통하여 고속 접속이 가능하도록 하는 방법을 개시한다. 본 발명에 따른 교환시스템과 가입자 접속단측간의 접속방법에 따르면, 교환시스템측의 전원공급 시점을 제외하고는 가능한 모든 경우에 왐스타트(Warm Start)로 처리된다. 또한 에러발생 시점에서 모든 조치를 취한 후 초기 접속과정으로 상태천이하는 과정을 삭제한다. 이러한 동작을 위한 교환시스템은 전원이 공급되는 시점과 매 일정한 주기마다 비활성화요구(DEACTIVATION REQUEST)를 반복적으로 송신하여 가입자측의 상태가 교환시스템의 상태와 일치되도록 한다. 그리고 또한 본 발명에 의한 접속방법에 따르면 교환시스템과 가입자 접속단간의 시그널링에는 전소어에러를 극소화할 수 있고 빠른 전송이 가능한 순환변경코드(CPC)가 이용된다.The present invention discloses a method for eliminating the unnecessary connection process between the subscriber connection side and the exchange system side, integrating them, and enabling high-speed connection through periodic subscriber side monitoring. According to the switching system according to the present invention and the connection method between the connection ends of the subscriber, all possible cases are treated as warm start except for the power supply time point of the switching system side. Also, after all the actions are taken at the time of error occurrence, the process of state transition to the initial connection process is deleted. The switching system for this operation repeatedly transmits a deactivation request at every predetermined period of time and at the time when the power is supplied so that the state of the subscriber matches the state of the switching system. Also, according to the connection method according to the present invention, a cyclic change code (CPC) is used for signaling between the switching system and the subscriber accessing section, which can minimize the bit error and enable quick transmission.
