And a fourth step of checking whether or not a ring signal indicating that trunk line is available is received from the private exchange, and detecting a tone input from the trunk line when receiving a ring signal indicating that trunk line is available from the private exchange. And a fifth process of transmitting or receiving a fax according to the received tone.

4. 발명의 중요한 용도4. Important uses of the invention

팩시밀리가 연결된 사설교환기에서 국선을 점유하기 위해 국선으로 스위칭할 때 국선비지인 경우 상기 팩시밀리가 자동으로 국선예약서비스를 대행하여 국선비지가 해제되는 순간을 감지하자마다 재다이알링을 수행하므로 송신지연시간을 줄이는 데에 사용한다.Transmit delay time when the facsimile detects the moment when the facsimile is cleared by the facsimile automatically when the facsimile is busy when switching to the trunk line to occupy the trunk line at the private exchange connected to the facsimile. Used to reduce
