Abstract
본 발명은 사설교환기에 있어서 가입자가 부재중인 경우 통화대기 기능을 입력하여 가입자 복귀시 통화할 수 있는 장치 및 방법에 관한 것으로, 음성합성회로를 디지탈 스위칭회로에 연결하여 가입자에게 부재중 음성안내 서비스를 제공하면 가입자가 음성안내서비를 듣고 교환기에 통화대기 기능을 입력시키게 되면, 메모리부의 특정 어드레스에 보관되어 착신자가 귀가하여 수화기를 들어 통화대기상태에 있는 가입자 기능코드를 입력하면 상기의 메모리부에 저장되어 있던 데이터에 의해 자동을 발신자에게 다이얼링되어 통화할 수 있도록 함으로써 트랙픽 효율을 높일 수 있다.The present invention relates to an apparatus and a method for making a call when a subscriber returns by inputting a call waiting function when a subscriber is absent in a private exchange. The present invention provides a voice guidance service to a subscriber by connecting a voice synthesis circuit to a digital switching circuit. When the subscriber hears the voice guidance service and inputs the call waiting function to the exchange, the subscriber is stored at a specific address in the memory unit and the receiver returns home to pick up the receiver and enters the subscriber function code in the call waiting state. Traffic efficiency can be increased by automatically dialing the caller to the caller.
