Design of a terminal for Telesvar (English)
Abstract [en]

Telia Telesvar is an automatic anwering machine that is provided in your stationary telephone at home. The drawback of this is that you cannot see if anyone has called you.

This report describes how a terminal for Telias Telesvar could be designed. Telesvar terminal will show in a display if anyone called you and show the incoming number. It will also play the spoken message in a built in speaker.

The design is based on some key components, LCD (Liquid Crystal Display) and DTMF (Dual Tone Multiple Frequency) and PIC16F877 microcontroller. These components are also described in the report.
