Now you can connect multiple Pentium PCs in your home or office to share files, printers, Internet connections, and more. Best of all, you don't need anything more than what's in the box! You won't be required to buy any cables or hubs to get your network started. This exciting new technology is being offered in compliance with the standards of the Home Phoneline Networking Alliance (HomePNA). The Linksys HomeLink Phoneline Network Card offers instant connectivity to multiple PC's over a home's existing telephone lines. You can network any PCI-equipped computer by connecting it to any telephone line. There's no need for a switch, a hub, or even any RJ-45 Ethernet cabling - the network runs on standard home-grade telephone cables. Simply install the card, plug the provided telephone cable into the wall, run the installation software, and go. The technology makes networking PCs at home easier than ever. Plus, there's a 10BaseT port on-board -- use it whenever you want to upgrade to a 10Mbps Ethernet. The HomeLink Phoneline Network Card utilizes Advanced Micro Devices' (AMD) PCnet-Home technology which allows phone lines to carry data at a 1Mbps transfer rate without interrupting regular telephone voice service (POTS) or feeds from a cable modem or Asynchronous Digital Subscriber Line (xADSL). You can talk on the telephone, download files from the Internet, and share resources over a network all at the same time. Every standard telephone jack in the home is capable of hosting a PC. You can connect up to 25 devices on any given phone number. With the HomeLink Phoneline Network Card, you will instantly transform the home's telephone wiring into an easily expandable network.
