发明名称 MF signal transmitting control apparatus/method for use in cordless telephone system
摘要 A multi-frequency (MF) signal transmitting control apparatus and method for use in a cordless telephone system, according to which a dial signal discrimination code within a transmitted dial signal causes an audio circuit to be turned off for a sufficient length of time to enable all of a multi-frequency signal to be sent to an exchange. As a result of the audio circuit being turned off at this point, the amount of noise received by a listener during a conversation in which dialing buttons are accidentally pressed by the bearer of the device is reduced.
