Claims (2)

디지틀 신호 변환 장치의 전반적인 동작을 제어하는 CPU와, 상기 CPU의 제어하에 NAS트렁크를 스위칭하는 주 및 예비의 NAS/CEPT 타임스위치와, 상기 CPU의 제어하에 CEPT트렁크를 NAS트렁크를 스위칭하는 주 및 예비의 CEPT/NAS타임스위치와, 상기 NAS/CEPT 타임스위치와 CEPT/NAS 타임스위치에 각각 연결되어 상기 CPU의 제어하에 주 또는 예비 타임스위치의 출력을 해당 트렁크로 출력하는 버퍼를 구비한 디지틀 신호변환장치의 타임스위치 이중화 방법에 있어서, NAS트렁크와 CEPT트렁크간에 상호 인터페이싱이 가능하도록 상기타임스위치를 통해 채널을 재할당하는 제1과정과, 상기 제1과정수행후 각 타임스위치들의 고장 플래그 리세트및 주 타임스위치를 동작시키고, 각 타임 스위치의 특정 스트림 출력단으로 진단 데이타를 출력하는 제2과정과,상기 제2과정 수행후 일정시간 주기로 주 타임스위치들의 고장 플래그 밎 진단 데이타를 검사하여 고장플래그가리세트 상태이고 입출력이 동일할시 주타임스위치들과 연결된 버퍼가 동작하도록 제어하는 제3과정과, 상기 제3과정에서 진단 데이타의 입출력이 상이할시 주타임 스위치 고장 플래그를 세트하고 버퍼를 제어하여 예비타임스위치로 절체하는 제4과정과, 주타임 스위치 플래그가 세트상태이거나 상기 제4과정 수행후 예비타임스위치들이 고장 플래그 및 진단 데이타를 검사하며, 고장플래그가 리세트상태에서 입출력이 동일할시 예비타임스위치들과 연결된 버퍼가 동작하도록 제어하는 제5과정과, 상기 제5과정에서 예비 타임스위치 고장플래그 세트상태이거나 진단데이타 상이할시 고장플래그를 세트시키고 상기 제1과정으로 되돌아가는 제6과정으로 이루어짐을 특징으로하는 디지틀 신호 변환장치의 타임스위치 이중화방법.CPU for controlling the overall operation of the digital signal converter, main and spare NAS / CEPT time switches for switching NAS trunks under control of the CPU, and main and spare for switching NAS trunks to CEPT trunks under control of the CPU. A digital signal conversion device having a CEPT / NAS time switch and a buffer connected to the NAS / CEPT time switch and the CEPT / NAS time switch, respectively, for outputting the output of the main or spare time switch to the corresponding trunk under the control of the CPU. In the time switch redundancy method of the present invention, the first process of reallocating a channel through the time switch to enable interfacing between the NAS trunk and the CEPT trunk; Operating a time switch and outputting diagnostic data to a specific stream output terminal of each time switch; and after performing the second process A third step of controlling fault flags of the main time switches at a predetermined time period to control the buffer connected to the main time switches when the fault flag is reset and the input / output is the same; and the diagnostic data in the third step The fourth process of setting the main time switch fault flag and controlling the buffer to switch to the preliminary time switch when the input / output is different from each other; A fifth step of controlling the diagnostic data to operate the buffer connected to the spare time switches when the input / output is the same while the fault flag is in the reset state; and in the fifth step, the preliminary time switch failure flag is set or diagnostic data. If it is different, the fault flag is set and the process returns to the first process. Time switch redundancy method of the digital signal conversion device according to claim a. 제1항에 있어서, 제1과정이 주 및 예비의 NAS/CEPT 타임스위치에서 5개의 NAS입력트렁크를 통한 디지틀데이타가 4개의 CEPT출력 트렁크로 변환 출력하도록 채널 할당하고, 주 및 예비의 CEPT/NAS 타임스위치에서4개의 CEPT입력 트렁크를 통한 디지틀 데이타가 5개의 NAS출력으로 변환 출력하도록 이루어짐을 특징으로 하는 디지틀 신호 변환장치의 타임스위치 이중화방법.The method of claim 1, wherein the first process allocates channels for converting digital data through five NAS input trunks to four CEPT output trunks at the primary and spare NAS / CEPT time switches, and the primary and spare CEPT / NAS. A time switch redundancy method of a digital signal converter, characterized in that the digital switch converts and outputs digital data through four CEPT input trunks to five NAS outputs. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
