애널로그 신호인 음성신호를 디지틀값으로 변환하여 컴퓨터의 mass storage device에 저장하거나 또는 저장된 디지틀 음성 데이터를 애널로그 신호로 재생하는 기술은 디지틀 음성신호처리의 가장 중요한 토대를 마련해 준다. 본고에서는 음성변경시스팀과 같은 저장형 통신시스팀의 구현에 있어서 반드시 구비되어야 할 기술인 음성신호의 실시간 디스크 저장문제를 NOVA 4/X 미니컴퓨터에서 해결한 것을 간단히 기술하였다.

The function of administration and maintenance on the TDX-1 digital switching system, which have been developed in ETRI(Electrotechnology and Telecommunications Research Institute), are reported. In administration, the functions of charging, statistics, data handling, man-mechine communication and I/0 device control are described. In maintenance, the function of fault detection and processing, status handling and alarm described.
