摘要： A Dual Tone Multi Frequency (DTMF) circuit for relaying DTMF digits includes a communication interface, a storage system configured to store a sampling window size, a DTMF test sequence, a returned DTMF sequence, and one or more DTMF digits, with the one or more DTMF digits to be transferred to a second DTMF circuit by the DTMF circuit, and a processing system. The processing system receives the one or more DTMF digits via the communication interface and an input sampling window, generates the DTMF test sequence and transmits the DTMF test sequence to the second DTMF circuit, compares the DTMF test sequence to a returned DTMF sequence received back from the second DTMF circuit, and if the returned DTMF sequence is not the same as the DTMF test sequence, adjusts the sampling window size of the input sampling window.
