Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

사설교환시스템에 연결된 중계대를 이용하여 착신호를 특정 국선으로 전환한 후 DTMF신호를 중계하는 기술이다.It is a technique to relay the DTMF signal after switching the incoming call to a specific trunk line using the relay station connected to the private switching system.

2. 발명이 해결하고자 하는 기술적 과제2. Technical Problems to be Solved by the Invention

사설교환기로 호출이 있은후 특정 국선가입자와 통화요구시 사설교환기에 연결된 중계대에서 자동으로 국선전환을 한 후 국선가입자가 입력시킨 DTMF를 특정 국선으로 송출하도록 한다.After the call is made to the PBX, the call is automatically switched from the PBX connected to the PBX when the call is requested to the PBX, and the DTMF inputted by the PBX is transmitted to the specific CO.

3. 발명의 해결방법의 요지3. The point of the solution of the invention

외부국선가입자가 사설교환기를 호출하여 특정국선 전화번호로 국선전환을 원할경우 사설교환기에 연결된 자동중계대에서 국선전환을 위한 안내메세지를 송출한 후 외부국선가입자로부터 국선전환 디지트를 입력시키도록 하여 자동으로 특정국선으로 전환 후 원하는 서비스를 받기위한 서비스코드를 수신하여 특정국선으로 송출되도록 DTMF신호를 중계한다.If a subscriber of an external trunk line calls a private branch exchange and wants to switch trunk line to a specific trunk line number, he / she sends out a message for switching trunk line from the automatic trunk line connected to the trunk line switch, inputs the trunk line switching digits from the trunk line subscriber, The service code for receiving a desired service after switching to a specific trunk line is received and the DTMF signal is relayed so as to be transmitted to a specific trunk line.

4. 발명의 중요한 용도4. Important Uses of the Invention

사설교환기에 연결된 자동중계대에 적용한다.Applies to an automatic relay station connected to a private exchange.
