Abstract
A telecommunication service function operating device for telephone comprises one telecommunication service function key keyboard, one detecting and controlling circuit, one ROM, one multi-frequency pulse output circuit, in which on the telecommunication service function key keyboard there are several special function keys(SV0~SVN), each special function key corresponding to one specific telecommunication service function, and sending signal to detecting and controlling circuit, then the detecting and controlling circuit generates one enable signal SERMOEN and several special function enable signals SV0EN~SVNEN to select pre-programmed special function code in memory. The detecting and controlling circuit output another enable signal SEROEN tomulti-frequency pulse output circuit, and memory output selected data to multi-frequency pulse output circuit, in the same time multi-frequency pulse output circuit generates and outputs multi-frequency signal DTMF corresponding to data or pulse signal PULSE to make telephone serve specific telecommunication function.
