1、普通拔号上网方式 现在很多人上网都是利用家中的电话线拔号上网,按照我国现在的电话线路状况,就算是使用56K的MODEM上网,其连接速率顶多也只能够上到50K左右,线路较差的只有40K左右,这样慢的连接速度,打开一个网站也要几分钟,甚至是十几分钟,下载一个稍大的软件就要花上一个多小时。如果有两条电话线,就可以用双MODEM上网,理论上其连接速率可达到112Kbps,但要当地的ISP支持PPP MULTILINK的网络协议,这样做不太切合实
1, ordinary dial-up Internet access Now many people are using the Internet phone line dial-up, according to China’s current telephone line conditions, even if the use of 56K’s MODEM Internet access, the connection rate at most only to 50K or so , The line is poor only about 40K, this slow connection speed, open a web site also a few minutes, or even ten minutes, download a slightly larger software will take more than an hour. If you have two phone lines, you can use dual MODEM Internet access, in theory, the connection speed up to 112Kbps, but to local ISP support PPP MULTILINK network protocol, this is not very realistic
