Internal PCI and PCI Express Modems for Windows Computers
These 56K modems go into the PCI or PCI Express slot inside a Windows desktop computer. They include the latest 56 Kbps standard, V.92, and also include earlier standards. The primary advantage of these internal modems is that they go inside your computer, minimizing any clutter. However, you do have to open your computer to install one of these internal modems.
