Abstract

본 발명은 전전자 교환기 망동기 장치에 관한 것으로, 전전자 교환기 망동기 장치를 구성함에 있어, 첫번째로 보조클럭 발생부의 위상차 제어를 주클럭과 자체발진클럭 위상차 데이타를 이용하므로 주클럭 발생부의 이상시 동시에 발생했던 보조클럭부의 이상문제는, 보조클럭 발생부가 주클럭 발생부로부터 받은 위상차 비교용 클럭과 자체 발진클럭의 위상차를 위상차 제어용 데이타로 이용하지 않고 주클럭 상태감시에 이용하면 보조클럭 발생부가 주클럭 발생부의 영향을 받지 않으므로 해결되고, 두번째로 클럭분배부에서 클럭발생부의 주클럭만을 이용하여 시시템을 공급하므로 인하여 주클럭상태가 나쁠때 시스템이 불안해지는 문제는, 이중화된 클럭 분배부가 각각 다른 클럭의 발생기로부터 기본클럭을 받아서 체배하고 분주하여 시스템에 공급하므로써 해결토록 한 것이다.The present invention relates to an all-electronic switch network device, in the configuration of the all-electronic switch network device, first, the phase difference control of the auxiliary clock generator using the main clock and the self-oscillating clock phase difference data, the abnormality of the main clock generator At the same time, the problem of the auxiliary clock part is that if the auxiliary clock generator uses the phase difference comparison clock received from the main clock generator and the phase difference between the self-oscillating clock as the phase difference control data and the main clock state monitoring is used, the auxiliary clock generator is mainly used. It is solved because it is not affected by the clock generator, and the system becomes unstable when the main clock is bad due to supplying the system by using only the clock clock of the clock generator. Receives the basic clock from the clock generator and multiplies and divides it into the system. It is solved by supplying.
