Interface Type::

PCI 2.2 compliant

Universal Compatibility:

The International Telecommunication Union (ITU) determines the technical protocols that communications devices must use to operate with each other. Modems that comply with ITU standards can "talk" to other standards-compliant modems and fax machines worldwide. The ITU has decided on a worldwide standard for 56K modem technology. With a 3Com U.S. Robotics modem, you can get 56K Internet access from any service provider who offers the ITU V.90.
