The U.S. Robotics 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, or troubleshoot your modems from almost anywhere. When failure is not an option, you need the world-class capabilities that only come from the top of the U.S. Robotics product line. Less
Using a modem is easy in a corporate office with a staff of computer gurus on call whenever you have a question. It’s tougher if you’re home alone or in a small company with no on-site support.
