Internet连接对今天的办公日益重要,但每个工作人员拨号上网都要占用一根电话线和一个调制解调器,不但浪费资源,而且增加了连接费用。研究表明,人们在使用Internet时主要是收发电子邮件和浏览WWW,而且很大一部分时间是在阅读和思考,这时他们的连接是空闲的。为了最大限度地利用连接带宽,各厂家纷纷推出共享Internet连接的解决方案,从功能强大的Proxy Server到几乎免费的共享软件和价格昂贵的拨号访问服务器。共享调制解调器上网把一个拨号连接的效能发挥到最大,得到了类似专线的连接效果(除了速度)。只使用一个调制解调器减少了电话线路的占用,而且只需要一个ISP的账号,节省了Internet连接费用。 《个人电脑》中国实验室测试了立基公司新推出的网梭(WebShuttle)。它可以通过以太网共享调制解调器或ISDN终端器连接Internet。作为小型办公局域网络连接Internet的解决方案,它可以通过一个高速串行口连接调制解调器,同时通过双绞线或同轴电缆 Internet connectivity is an increasingly important part of today’s office, but each worker dials up to a telephone line and a modem for dial-up access, wasting resources and increasing connection costs. Research shows that people mainly use the Internet to send and receive e-mail and browse the WWW, but most of the time is reading and thinking, when their connection is idle. To maximize the connection bandwidth, manufacturers have introduced solutions for sharing Internet connections, from powerful Proxy Servers to virtually free shareware and expensive dial-up access servers. Sharing Modem Internet to a dial-up connection to maximize the effectiveness of the connection has been similar to the green effect (except speed). Using only one modem reduces the telephone line occupancy, and requires only one ISP’s account, saving on Internet connection costs. The “PC” China Lab tested the new WebShuttle by Liji. It can connect to the Internet via an Ethernet shared modem or ISDN terminal. As a solution for connecting a small office LAN to the Internet, it can be connected to a modem via a high-speed serial port while using a twisted pair or coaxial cable
