Data/Fax Modem - USR3453C

The USRobotics Courier 56K Business Modem with V.Everything and V.Everywhere technology is the latest in the distinguished Courier line. Many modems claim reliability, but few match the real-world performance of Courier modems. Even fewer offer the multitude of advanced business features found on this modem: global usage, Carrier Loss Redial, and Dial and Dialback Security. Remote management capabilities let you configure, set up, update or troubleshoot your modems from almost anywhere. Each Courier includes a VersaPower Kit - a 110V to 240V power supply that includes clip-on plugs for other regions, in addition a clip-on power cord adapter that can be used to make it an inline power supply is available in all Courier accessory kits. When failure is not an option, you need the world-class capabilities that only come from the top of the USRobotics product line.
