Abstract

본 발명은 사설 교환기에 관한 것으로, 임의의 내선 가입자가 통화를 원하는 국선 가입자를 호출하였을 경우 국선 가입자가 통화중에 있거나 일정시간 동안 호출된 국선 가입자로 부터 오프 훅 신호를 검출하지 못해 부재중으로 인지되면 내선 가입자가 통화를 원하는 시간을 예약 설정하여 통화로가 형성되지 못한 국선 가입자를 자동으로 호출하도록 한 것이다.The present invention relates to a private exchange. When an extension subscriber calls a trunk line subscriber who wants to talk, the subscriber station is busy or does not detect an off-hook signal from the trunk line subscriber called for a certain time. By setting a reservation time for the subscriber to make a call, the subscriber to the CO line which has not been established is automatically called.

본 발명은 사설 교환기에 접속되어 있는 내선 단말기의 가입자가 국선 가입자를 호출하여 통화로의 연결을 시도할시 호출된 국선 가입자가 통화중에 있거나 부재중으로 판단되어 통화로의 접속을 희망하는 예약시간을 설정하여 저장하면 타이머 수단을 통하여 설정된 시간을 카운팅한후 설정된 시간이 검출되면 예약을 설정한 내선 단말기를 자동 호출한다. 이후 국선 단말기로 부터 송수화수단의 오프 훅을 검출하면 자동 다이얼링을 실행하여 통화로를 형성함으로 내선 단말기 사용자에게 편리성이 제공되고, 중요한 업무통화의 망각이 배제되어 업무의 효율성이 제공된다.According to the present invention, when a subscriber of an extension terminal connected to a private exchange attempts to connect to a call by calling a CO line subscriber, the reserved CO subscriber is determined to be busy or absent, and thus sets a reservation time for connection to the call. If the stored time is counted by the timer means, and if the set time is detected, the station which set the reservation is automatically called. Then, when the off-hook of the handset means is detected from the CO line terminal, automatic dialing is executed to form a call path, thereby providing convenience to the extension terminal user, and eliminating oblivion of important business calls, thereby providing work efficiency.

사설 교환기의 국선 자동발신방법Automated Calling of Private Lines

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 사설 교환기의 국선 자동발신장치의 구성도.1 is a block diagram of a trunk line automatic transmission device of a private exchange according to the present invention.

Claims (3)

사설 교환기에 있어서, 상기 사설 교환기에 접속되는 내선 단말기 사용자가 발신음을 확보한 후 임의의 국선 단말기와 통화로를 연결하기 위해 입력하는 국선점유 코드와 국선 단말기의 전화번호를 메모리수단의 소정 테이블에 설정하는 제1과정과, 상기 제1과정 실행후 국선 단말기로 부터 비지 톤이 검출되거나 일정 시간 지속되는 링백 톤에 따라 국선을 복구한후 발신음을 재 확보하여 예약 다이얼링을 등록하기 위해 입력되는 소정의 기능 코드와 호출을 원하는 예약시간을 검출하면 송수화수단의 온 훅에 따라 메모리수단의 소정 테이블에 예약 다이얼링의 등록을 설정하는 제2과정과, 상기 제2과정 실행후 상기 제1과정에서 메모리수단의 소정 테이블에 설정된 국선점유 코드와 국선 단말기의 전화번호를 복사하여 예약전화번호로 등록하는 제3과정과, 상기 제3과정 실행후 타이머수단의 카운팅으로 상기 제2과정에서 예약 설정된 시간을 검출하면 예약설정한 내선 단말기를 검출한후 자동호출하여 오프 훅여부를 검출하는 제4과정과, 상기 제4과정 실행후 예약설정한 내선 단말기의 오프 훅신호를 검출하면 예약시간과 설정된 임의의 국선 단말기를 자동 다이얼링하여 통화로를 연결하는 제5과정을 포함하는 것을 특징으로 하는 사설 교환기의 국선 자동발신방법.In a private exchange, a station number occupied by a user of an extension terminal connected to the private exchange to secure a dial tone, and a telephone number of a trunk line terminal inputted to connect an arbitrary trunk line terminal to a call path is set in a predetermined table of a memory means. A predetermined function is input to register reserved dialing by resetting a ring tone after recovering a CO line according to a ring tone to which a busy tone is detected from a CO line terminal after executing the first process, or the ringback tone lasting for a predetermined time. A second step of setting a registration of the reserved dialing in a predetermined table of the memory means according to the on-hook of the handset means upon detecting the code and the reservation time desired for the call; and the execution of the second means after the execution of the second process. Lesson 3 for copying the CO line occupancy code set in the predetermined table and the phone number of the CO line terminal to register as a reserved phone number And a fourth step of detecting whether or not an off-hook is detected by automatically calling a preset station when the preset time is detected in the second process by counting timer means after the execution of the third process. And detecting a off-hook signal of the reserved station after the execution of the process, the fifth process of automatically dialing a predetermined time and a predetermined trunk line terminal to connect a call path. 제1항에 있어서, 상기 제2과정에서 설정되는 예약시간은 국선 단말기를 호출하는 신호의 송출시간과, 호출신호의 반복횟수및, 호출신호의 온,오프에 대한 주기가 설정되는 것을 특징으로 하는 사설 교환기의 국선 자동 발신방법.The reservation time set in the second process is characterized in that the transmission time of the signal for calling the CO line terminal, the repetition frequency of the call signal, and the period for turning on or off the call signal are set. Automated call-out of private exchanges. 제1항에 있어서, 상기 제4과정에서 예약 설정한 내선 단말기를 자동호출할시로 소정횟수의 링백 톤이 검출될때 까지 오프 훅신호를 검출하지 못하면 내선 단말기가 설정한 국선 단말기의 자동 호출등록을 클리어 하는 것을 특징으로 하는 사설 교환기의 국선 자동 발신방법.The method according to claim 1, wherein if the off-hook signal is not detected until a predetermined number of ringback tones are detected when the reserved terminal is automatically called in step 4, the automatic call registration of the trunk line terminal set by the extension terminal is performed. Automatic trunk line transmission method of a private exchange characterized in that the clearing. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
