Abstract

본 발명은 통신장비의 식별 송수신 방법 및 방법에 관한 것으로서, 기능식별신호를 송,수신하여 두 기종간의 통신 실패를 방지함과 아울러 모든 통신기기의 오프훅크전에 간단한 정보를 송신하고 DTMF의 톤 조합으로 영문은 물론 숫자까지 다양하게 송신함은 물론 수신기종에서 송신기종에 적합하게 통화 도수의 산정없이 자동연결하도록 한 것이다.The present invention relates to a method and method for identification transmission and reception of communication equipment, which prevents communication failure between two models by transmitting and receiving a function identification signal, and transmits simple information before off-hooking of all communication devices. Not only English but also various numbers are transmitted, and the receiver type is appropriately connected to the transmitter type without calculating the frequency of the call.

이와같은 본 발명은 송신측으로 부터의 링신호와 통신기종의 식별신호 입력유무를 검색하는 제1단계와, 상기 검색결과 통신기종의 식별신호가 전화이면 릴레이를 절체하여 전화통화루프를 형성하고 훅크오프를 하는 제2단계와, 상기 검색결과 통신기종의 식별신호가 팩시이면 릴레이를 절체하여 팩시통화루프를 형성하는 제3단계로 이루어짐으로써, 달성되는 것이다.As described above, the present invention provides a first step of searching for a ring signal from a transmitting side and whether an identification signal of a communication type is input, and if the identification signal of the communication type is a telephone, switching the relay to form a telephone call loop and hooking off. And a third step of switching the relay to form a facsimile call loop if the identification signal of the search result communication device is a facsimile.

Claims

A call / ringback tone detection means for detecting a call signal and a ringback tone from a transmitter, and transmitting an identification signal to the transmitter according to the signal detected by the call / ringback tone detection means and controlling overall system operation of the communication equipment. A ring detection means for detecting a micom, a ring signal from a transmitting side, a communication identification detecting means for detecting and inputting an identification signal of a communication model output from the ring detection means, and inputting the control signal to the micom; A first relay for switching the ring signal and the communication identification signal to a fax and a telephone on the receiving side, and switching the ring signal detected from the ring detecting means to the telephone side by the control signal of the microcomputer. A relay, a third relay for switching between a transmitting side and a receiving side, and switch detection means for sensing on / off of the third and fourth relays; Identification of the transmitting and receiving device over a communication equipment.

A first step of retrieving a ring signal from a transmitter and the presence of an identification signal of a communication model; and a second step of switching a relay to form a telephone call loop and hooking off if the identification signal of the communication model is a telephone as a result of the search; And a third step of switching the relay to form a facsimile call loop when the identification signal of the communication type is a facsimile as a result of the search.

The method of claim 2, wherein the identification signal of the communication device is set to "0" for a telephone and "1" for a facsimile.
