V.Everything® and V.Everywhere™ Technology
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. When
failure is not an option, you need the world-class capabilities that only come
from the top of the USRobotics product line.
