In order to provide users with broadband and high - speed services via the existing copper lines , new technologies are on the horizon , with xdsl and cable modem as the two most competitive ones 为了继续发挥铜缆的作用，尽可能地向用户提供宽带和高速业务，已经出现了利用铜缆来提供高传输速率的新技术。
Files built with dynamic hypertext markup language ( dhtml ) load more quickly . you can accommodate the latest transmission technologies , including cable modems , through support for asynchronous transfer mode technology 通过对异步传输模式技术的支持，可以适应包括电缆调制解调器在内的最新传输技术。
In this process , the xdsl technology led by adsl is key tool for realizing such an upgrade . the hfc system and the asymmetric cable modem are solutions to revamping the existing catv network 以adsl为代表的xdsl数字用户线接入技术是一种重要的改造手段； hfc系统和非对称cablemodem则是改造现有catv网的技术方案。
Cable modem width is taken the technology , and the clear superiority . need to point out that the cable television net of our country in is seen still existing the question of disequilibrium 同时，带宽问题一直困扰着互联网的管理者和广大用户，大多数用户使用拨号上网的方式，但目前电信网的带宽还远远不能满足用户的需要。
Interoperability - the ability of a device or system to work with others of a different make . interoperable cable modems , for example , should work on any computer in any cable system 兼容性- -一种设备或系统能够同不同厂家生产的设备或系统兼容的性能。例如，具有性能的有线电视调制解调器适应任何有线电视系统中的任何计算机操作系统。
Further , even after having wound down the cable modem business , the strong growth in its digital video solutions segment could be clouded by more declines in its subscriber product line segment 不仅如此，该公司虽然已经因为线缆数据机业务而遭受创伤，其数位视讯解决方案部门的强劲增长还可能被订购产品系列部门更大幅度的下滑所抵销。
The modulation used by a dial - up modem is very different from that used by a cable modem , because a twisted - pair phone line and a coaxial cable differ in the amplitude , frequency and phase of the signals they can carry 拨接数据机所使用的调制，与缆线数据机大相迳庭，因为电话的双绞线与同轴电缆所携带的讯号，各具有不同的振幅、频率与相位。
