GENERAL DESCRIPTION

The EM91450 is a series of tone/pulse switchable dialers that is composed of T/P dialer. The EM91465 provide modern LCD drivers series data output port, which can display modern function operating icons. The EM91450 series provide necessary functions of telephone set for application in any environment, such as Pulse dialing, Tone (DTMF) dialing, Handfree dialing, keying tone ,and lock functions. The lock function is designed to inhibit toll dialing operation. Beside this, ring detector and SDO (Serial Data Output) functions are provided in advance version. Ring detector can prevent illegal dialing from pocket dialer. The SDO is designed to drive LCD driver and voice synthesizer. In this application, the dialing numbers and modern function operating icons can be displayed on LCD screen with LCD driver (EM32100 or EM32117 ). The EM91450 has a special I.P. P. detect function (Illegal Parallel Phone Detect) can prevent the illegal connect external Phone. The I.P.P. will detect the illegal user. When illegal user pickup phone, the function will alarm and send the alarm signal to the telephone line to interfer the illegal dialing.
