数字调试电话的设计与实现

Designing and Implementation of the Digital Debug Telephone

设计了数字调试电话系统 ,实现调试电话中的语音信号的数字编码叠加和信令控制功能 ,并且自行定义信令帧结构和令牌传输方式 ,实现两点或多点电话通信功能。

In this paper, the digital debug telephone system is designed, the addition of the digital coding of the voice signal in debug phone is realized and it also designs the structure of the signaling and the Token-Ring transportation form as well as realizes the controlling function of the signaling.
