Abstract

MCA방식 무선전화기에 있어서, 수동으로 채널을 변경할 때 국선을 처리하는 방법에 관한 것이다.In an MCA wireless telephone, the present invention relates to a method for processing trunk lines when manually changing channels.

통화도중 혼신이나 잡음을 제거하기 위해 수동으로 채널을 변경할 때 상대 통화자에게 보류음이나 상기 보류음과 유사하게 전자식 다이알음을 송출함으로써 새로운 채널로 변경하는 동안 상대 통화자나 전화가 끊어진 것으로 오인하여 전화를 끊어버리게 되는 것을 방지한다.When you manually change the channel to remove any interference or noise during a call, the caller is mistaken as the other party or the phone is disconnected during the change to the new channel by sending a hold tone or an electronic dial tone similar to the above hold tone. To prevent them from breaking.
