基于MT8880的一键拨号电话系统设计

　　针对煤矿井下调度及紧急救援系统的需求，以DTMF编解码模块为核心，设计了具有自动拨号功能的新型电话系统。该系统利用MT8880对DTMF信号的编解码功能实现一键拨号和远程设置，通过检测振铃和忙音信号，完成自动摘机和挂机过程，配合AGC等外围电路达到话音清晰流畅的效果。　　Abstract: 　　To meet the demand for mine scheduling and emergency rescue system， with using DTMF signal codec as the core， a new telephone system was designed with automatic dialing function. In the system， the DTMF signal encoding and decoding function of MT8880 was used to achieve one-touch dialing and remote setting. The circuit detects the ringing and busy signal， and then completes automatic off-hook and hangup. With AGC(Automatic Gain Control) and other peripheral circuits， the voice was regulated to a clear and smooth effect.
