摘要
论述了CableModem的工作原理、传输模式和技术标准 ,以及基于CableModem接入的有线电视宽带网络解决方案 .CableModem通过有线电视CATV的某个传输频道进行调制解调 ,其他空闲的有线电视频道仍可用于传输有线电视信号 ,所以优越于传统Modem :不占用电话线 。
The working principle,transmission model and broad band networks solution to Cable Modem,which modulated/demodulated via some of transmission frequency bands of CATV,were introduced,and the other frequency bands still can be used to transmit CATV signal. It doesn't need to be paid for more telephone fee and dial-up and connect permanently like others.
