Digi DataFire BRI ISDN U I/F PCI Adapter

The Digi DataFire® BRI ISDN adapter is one of the fastest ISDN accelerator adapters on the market today. It provides high-speed access to networks or the Internet with breakthrough simplicity and affordability. Engineered for speed and ease of use, the DataFire BRI ISDN adapter is easy to install and maintain. With the U version, there’s no need for a line terminator or power supply, so installation is as simple as placing the adapter in an open expansion slot of any ISA or PCI bus PC and connecting it directly to an ISDN Basic Rate Interface (BRI) phone line. This revolutionary design reduces overall equipment cost, too. The insightful blend of simplicity and affordability makes DataFire BRI the ideal remote LAN or Internet access solution for telecommuters, branch offices or other locations that have the need for advanced ISDN communications technology.
