Abstract

본 발명은 ISDN전화기에 T/R인터페이스 기능을 내장하여 아날로그 SLT나 음성 자동 응답기를 부착할 수 있게 함으로서 다기능 단말기로서의 가치를 높일 수 있도록 한 종합 정보 통신망의 자동응답 전화기 및 그 제어방법에 관한 것이다.The present invention relates to an automatic answering telephone of an integrated information communication network and a control method thereof, by adding a T / R interface function to an ISDN telephone to attach an analog SLT or an answering machine to increase the value as a multifunctional terminal.

이러한 본 발명은 자동 응답 모드에서 상대방의 호출이 있으면, 아날로그 TA음성 코덱부(10)를 통해 T/R 인터페이스부(12)에 접속된 장치와 상대방의 단말기 상호간에 데이타를 전달하도록 데이타 통로를 전환하고, 링 발생부(11)에서 일정 횟수 이상 벨을 울릴때까지 T/R인터페이스부(12)에 접속된 장치가 동작하지 않으면 망측에 통화 불능 상태임을 통보하고 접속을 해제하게 된다.In the present invention, when the other party calls in the answering machine mode, the data path is switched to transfer data between the device connected to the T / R interface unit 12 and the terminal of the other party via the analog TA voice codec unit 10. If the device connected to the T / R interface unit 12 does not operate until the ring generator 11 rings for a predetermined number of times, the network side is notified that the call is unavailable and the connection is released.

Claims

Analog TA audio codec unit connected to the central processing unit 3 for controlling the overall operation of the ISDN terminal system, and a network connection unit 2 for controlling connection with the ISDN and the telephone, for analog / digital conversion or digital / analog conversion of voice signals. (10), the ring generator (11) connected to the analog TA voice codec unit (10) to generate a ring signal when the other party calls, and the T / T for controlling the connection of the voice answering machine (G3 facsimile, SLT, etc.) Monitors the hook status and pulse dialing of the device connected to the R interface unit 12, the DTMF receiver unit 13 receiving the DTMF signal from the T / R interface unit 12 side, and the T / R interface unit 12 side. And a hook state and dial detection unit (14) and a powering unit (15) for supplying power to each of these units.

Checking whether the call is in the auto answer mode when there is a call from the other party; switching the data path to the analog TA side in the autonomous response mode; and checking whether a device connected to the T / R interface unit is in an off-hook state. And, in the on-hook state until the bell rings for a predetermined number of times, notifying the network that the call is incapable, and releasing the connection. And answering one of the two telephone calls.
