窄带及宽带接入因特网技术的分析

Technology of Accessing Internet with Narrowband and Wideband Networks

在指出利用低速Modem和PSTN拨号接入Internet所存在的既占用PSTN网络资源又会使PSTN拥塞，而需要对现有PSTN进行改造问题的基础上，介绍和分析了解决上述问题的两种窄带接入和两种比较便捷的宽带接入的技术以及它们的优缺点，认为要实现真正的宽带接入还得向FTTC和FTTH的方向发展。

： The paper pointed out to access Internet by using low－speed Modem and PSTN dialing not only occupied PSTN network resources ， but also made PSTN congestion． It also introduced and analyzed two kinds of easy narrowband and wideband access technology for solved above problems and its good and weak points． The author considered that the true wideband access network should be developed towards FTTC and FTTH．
