EM91450 series provide necessary functions telephone application environment, such Pulse dialing, Tone (DTMF) dialing, Handfree dialing, keying tone ,and lock functions. lock function designed inhibit toll dialing operation. Beside this, ring detector (Serial Data Output) functions provided advance version. Ring detector prevent illegal dialing from pocket dialer. designed drive driver voice synthesizer. this application, dialing numbers modern function operating icons displayed screen with driver (EM32100 EM32117 EM91450 special I.P. detect function (Illegal Parallel Phone Detect) prevent illegal connect external Phone. I.P.P. will detect illegal user. When illegal user pickup phone, function will alarm send alarm signal telephone line interfer illegal dialing.
