摘要：
A tone signal received in a telecommunications network is bandpass filtered based on an identified type of the received tone signal, providing a bandpass filtered tone signal. The tone signal is also bandstop filtered based on the identified type of the received tone signal, providing a bandstop filtered tone signal. The bandpass filtered tone signal and the bandstop filtered tone signal are analysed and the received tone signal is quantified based on the analysis result.
