(TELEPHONE CALLER IDENTIFICATION SYSTEM) This system is implemented in the US ROBOTICS MODEMS SPORTER Vi Series. I want to build this with pics 16C84 or others depending of software requeriments or algorithm complexity. Other topic of my interest is : Somebody have specifications for 16KHZ TELEPHONE TAXATION SYSTEM ? Please point to WWW Site for ISO specifications !!! Circuits schematics or software algorithm on this topics are welcomed... Thank in advances ------------------------------- Hugo J.
