Abstract

본 발명은 사설 교환기의 내선 가입자 인터콤 기능에 관한 것으로 특히 다기능 전화기를 사용하지 않고도 일반 전화기를 이용하여 단축인터콤 기능이 가능하게 하는 것이다.The present invention relates to an extension subscriber intercom function of a private exchange, and in particular, to enable a short-term intercom function by using a general telephone without using a multifunctional telephone.

종래의 기술은 다기능 전화기 혹은 메모리 기능이 첨가된 전화기긴 경우 그 설치 비용이 많이들고 전화기를 사설 교환기에서 분리했을 경우 보관된 번호들이 지워져버려 다시 등록해야 하는 불편함이 있었으며 단순히 내선/국선번호 호출만 가능했을 뿐 회의 통화, 전환, 연결대기, 할입등의 기능 사용시 내선 가입자 번호를 전부 다이얼해야하는 불편함이 있었다.The conventional technology is expensive to install a multi-function phone or a phone with a memory function, and when the phone is disconnected from the private exchange, the stored numbers are erased and the user needs to register again. Although it was possible, it was inconvenient to dial all extension subscriber numbers when using functions such as conference call, transfer, connection waiting, and installment.

본 발명은 사설 교환기의 시스템 메모리에 내선 가입자 각각에 해당하는 내선번호기억 테이블을 형성시켜 교환기와 연결된 내선 가입자로 부터 입력되는 해당 내선 가입자 정보를 기억시키므로써 단축 기능이 없는 전화기로도 구내 교환기 기능을 할 수 있게 하는 것이다.The present invention forms an extension number storage table corresponding to each extension subscriber in the system memory of the private exchange, and stores the corresponding extension subscriber information input from the extension subscriber connected to the exchange, thereby enabling the function of the branch exchange even with a telephone without a shortening function. To do it.

Description

Extension subscriber intercom function of private exchange

Claims

The central processing unit (2), the system memory (3), the switching memory unit (4), the tone control unit (5), the relay station (6), the message interface (7), the subscriber control unit (8), and the subscriber circuit unit (9); In the private exchange system composed of the power supply unit 10 and the ring power supply unit 11, an extension number storage table TA-TH for storing extension intercom subscriber information of each extension subscriber AF in the system memory 3 is stored. The extension subscriber intercom function of the private exchange, characterized in that the short-term extension information of the extension subscriber is stored in the exchange itself so that the internal intercom function is possible even with a regular telephone.
