Description: Voice over IP (VoIP) is undoubtedly a powerful and innovative communication tool.
Compared with the public switched telephone network (PSTN), VoIP off ers the benefi t
of reducing communication and infrastructure cost. This makes it possible for everyone
to easily keep in touch with family, friends, and clients around the world. Furthermore,
VoIP has the potential to create new and att ractive communication tools by
integrating with various applications, such as Web systems, presentation soft ware, and
photo viewers. In the near future, we expect VoIP to provide a rich multimedia communication
service.

Description: 目前，人们的生活向着智能化，人性化的方向发展着。越来越多的高科技进入了我们的生活中。其中家用电器的远程控制也正被推广开来。本着低耗能、无污染、使用方法简单方便的原则。本文设计的是一种基于AT89S51单片机的远程电话控制系统。该系统是以AT89S51为核心、通过现在的个人通信手段，实现基于PLMN（陆基移动通信网）和PSTN（公用电话交换网）的电话远程控制系统。根据CCITT及我国标准共同规定，电话远程控制系统（ITRCS），以PSTN与PLMN通信网作为传输介质，以部分标准程控交换信令（DTMF双音多频型号，振铃型号，回铃音信号等）作为系统控制命令，使用户实现在远端通过移动电话或者固定电话发送DTMF双音多频信号对近端电器设备进行远程控制。本次设计的电话远程控制系统不需要再进行专门的布线，不占用无线电频率资源，从而可避免电磁污染。用户只有输入正确的密码才能控制家电，从而提高了安全性。该系统设计实用，功能灵活多样，可靠性高，操作方便，可以广泛地应用于家庭或者其它场所的智能控制。
