Abstract

본 발명은 사설교환기에 관한 것으로 외부에서 국선을 통하여 사설교환기에 연결된 다른 국선을 이용하여 외부로 통화를 할 경우 중계접속을 요구하는 사용자의 고유번호와 중계접속에 대한 기능번호를 확인하여 사용자의 중계접속을 제한하며 중계접속되는 송수신 통화정보를 기록저장하여 불필요한 통화의 배제로 업무의 효율성이 향상된다.The present invention relates to a private exchange, when a user makes an external call using another trunk line connected to a private exchange through a trunk line from the outside, the user relays by checking the unique number of the user requesting the relay connection and a function number for the relay connection. It restricts access and records and transmits and receives relayed call information, thereby eliminating unnecessary calls and improving work efficiency.

본 발명의 사설교환기가 중계접속을 요구하는 DTMF 신호를 감지하면 DTMF 신호에서 사용자의 고유번호 및 중계접속에 대한 기능번호를 분석하는 단계와, 분석된 DTMF 신호가 중계접속 허락신호이면 중계접속을 요구한 사용자측에 발신음을 송출하고 국설교환기를 접속하는 단계와, 접속된 국선을 통한 통화정보를 저장하고 송수화 수단의 온 훅 여부를 감지하는 단계 및, 분석된 DTMF 신호가 중계접속 불허신호이면 그에 대한 톤 신호 또는 메세지를 중계접속을 요구한 단말기의 사용자측에 송출하는 단계를 포함한다.If the private exchange of the present invention detects a DTMF signal requesting a relay connection, analyzing the user's unique number and the function number for the relay connection from the DTMF signal, and if the analyzed DTMF signal is a relay connection permission signal, the relay connection is requested. Transmitting a dial tone to a user side and connecting a local exchange; storing call information through the connected trunk line and detecting whether the handset means is on-hook; and if the analyzed DTMF signal is a relay disallowed signal, Transmitting the tone signal or message to the user side of the terminal requesting the relay connection.

Claims (1)

사설교환기에 있어서, 외부의 국선을 통해 사설교환기의 다른 국선을 이용한 중계접속을 요구하는 DTMF 신호가 인가되면 DTMF 신호에서 중계접속을 원하는 사용자의 고유번호 및 중계접속에 대한 기능번호를 분석하는 제1단계와, 상기 제1단계 수행후 분석된 DTMF 신호가 중계접속이 허락된 신호로 판단되면 DTMF 신호를 인가한 사용자의 단말기 측에 발신음을 송출함과 동시 사용자를 기록저장하고 국설교환기를 접속하는 제2단계와, 상기 제2단계 수행후 접속된 국선을 통해 수행되는 통화정보를 메모리 수단에 저장함과 동시 송수화 수단의 온훅을 연속적으로 감지하는 제3단계 및, 상기 제1단계의 분석에서 사용자의 고유번호 또는 중계접속에 대한 기능번호가 중계접속이 허락되지 않은 신호로 판단되면 중계접속 불허에 대한 톤 신호 또는 음성안내메세지를 중계접속을 요구한 사용자의 단말기 측에 송출하는 제4단계를 포함하는 것을 특징으로하는 사설교환기의 국선중계시 사용자 제한 방법.In a private exchange, if a DTMF signal for requesting relay connection using another trunk line of a private exchange is applied through an external trunk line, a first number for analyzing a unique number of a user who wants a relay connection and a function number for the relay connection are analyzed in the DTMF signal. And if the DTMF signal analyzed after performing the first step is judged to be a signal for relay connection, sending a dial tone to the terminal of the user who has applied the DTMF signal, recording and storing the simultaneous user, and accessing the local exchange. A second step of storing the call information performed through the CO line connected after performing the second step in a memory means and continuously detecting the on-hook of the simultaneous handset means; and in the analysis of the first step, If the unique number or function number for the relay connection is judged to be a signal for which the relay connection is not allowed, the tone signal or voice guidance message for the relay connection disallowed And a fourth step of transmitting the message to the terminal of the user requesting the relay connection. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
