Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
간이 교환시스템에서 보류시 착신된 국선이 절단될 시 통화기능을 중지시키는 기술이다This is a technology to stop the call function when the trunk line is disconnected when it is suspended in the simple exchange system.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
간이교환 시스템에서는 국선 또는 내선전환을 할 때에나 보류시에 상대방이 전화를 끊을시 보류한 내선가입자나 전화된 내선 또는 교환수가 전화를 받았을시 에러톤을 듣고 전화를 끊는 불편한 문제를 해결한다.The simple switching system solves the problem of receiving an error tone and hanging up when a suspended subscriber or a telephone extension or an attendant receives a call when making a trunk line or an extension, or when the other party hangs up during a call.
3. 발명의 해결방법 요지3. Solution Summary of the Invention
국선과 통화중인 내선가입자가 착신전환이나 국선 보류를 시키고 상기 보류된 국선으로 보류음악을 송출하고, 상기 보류음악송출중에 국선톤신호를 검사하여 에러톤유무를 검울하며, 상기 에러톤이 검출될 시 국선라인을 절단하고 각 내선에 지원되는 통화기능을 중지시킨다.When an extension subscriber who is on a call with a CO line makes a call transfer or a CO line hold, and transmits a reserved music to the reserved CO line, checks whether a CO line tone signal is detected during the transmission of the reserved music and detects an error tone, and when the error tone is detected. Cut off the CO line and stop the call function for each station.
