I'm quite surprised that a telecoms consultant is not certain of the problems caused by a mismatch of the terminating impedance to the source impedance..... > > I assume you are not referring to return loss during DTMF transmissions. Its possible that poor return loss could affect performance in conjunction with some systems (please see EG 201 121) but I think Ted is referring to transmission of data.
