ISDN作为一种远程访问技术,近年来一直为电信运营商所看好。经过了几年的投入和孕育,又恰逢Internet应用蓬勃发展,ISDN市场几乎是瓜熟蒂落,而此时却出现了线缆调制解调器(Cable Modem)。 线缆调制解调器利用已有广泛用户基础的有线电视网作通信网,使一般家庭可以用较高的带宽进行数据通信,接入Internet,实现远程访问。一经推出,即被认为是将来家庭用户连接信息高速公路的有效渠道。市场分析人士认为,即使电信商正积极地解决着曾困扰ISDN应用的一些问题,如价格和安装等,但线缆调制解调器所能提供的高带宽及已有的广泛的基础设施实在具有太大的优势。线缆调制解调器理
As a remote access technology, ISDN has been favored by telecom operators in recent years. After a few years of commitment and ingenuity, but also coincided with the vigorous development of Internet applications, ISDN market is almost ripe, but at this time there has been a cable modem (Cable Modem). Cable modems use a wide range of user-based cable television networks for communication networks, so that the average family can use the higher bandwidth for data communications, Internet access, remote access. Once launched, it is considered as an effective channel for home users to connect to the information superhighway in the future. Market analysts believe that even though telcos are aggressively solving some of the problems that have plagued ISDN applications, such as price and installation, the high bandwidth that cable modems can provide and the wide range of existing infrastructure is too large Advantage.
