Abstract
본 발명은 디지탈 국설 교환기의 메시지 대기방법에 관한 것이다.The present invention relates to a message queuing method of a digital public switched telephone system.
종래의 DID방식의 디지탈 국설 교환기는 외부 가입자가 간이 교환기의 내부가입자를 호출하였을 때, 해당 가입자가 부재중이거나 통화중일 경우에 외부 가입자는 전화를 끊은 후, 다른 내부가입자를 호출하여 자신의 전화번호를 알려주어 연락을 해달라고 부탁하거나, 추후 다시 호출을하여 원하는 내선 가입자와 통화를 해야 하는 불편한 문제점이 있었다.When the external subscriber calls the internal subscriber of the simple exchange system and the subscriber is absent or is in a call, the external subscriber disconnects the telephone and then calls another internal subscriber to dial his or her telephone number There has been a problem that it is inconvenient to ask for a contact to be informed, or to make a call with a desired extension subscriber by calling again later.
따라서 본 발명은 상기한 종래기술의 문제점을 개선코자하여 DID 방식으로 호출한 국선 사용자가 원하는 간이 교환기의 내부 가입자와 통화를 이루지 못하고 온 후크한 경우 간이 교환기에서는 디지탈 국설 교환기에서 제공하는 발신자 번호를 기록하여 각 내선의 대기 리스트에 남김으로써, 남겨진 대기 국선번호들은 이후 유효해진 내선 가입자가 쉽게 알 수 있도록 일시 정보와 함께 액정표시부에 표시됨과 아울러 사용자의 요구에 의해 자동적으로 다이얼하도록 하는 것이다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a digital subscriber line switching system in which when a trunk line user called by a DID method fails to make a call with an internal subscriber of a desired trunk exchange, The remaining standby station numbers are displayed on the liquid crystal display together with the date and time information so that they can be easily recognized by the validated extension subscribers, and automatically dialed according to the user's request.
