The 56K Faxmodem USB modem is hot-swappable (installs/uninstalls automatically) and is bus-powered so it doesn't require an external power supply. ICN monitors online activity and lets you take full advantage of Modem on Hold - choose to accept or reject incoming calls while online. ControlCenter supports Modem on Hold and allows you to configure V.PCM speeds. Instant Update can download software updates automatically to your PC. U.S. Robotics is proud to introduce the V.92 international standard. V.92 offers more flexibility and greater control over your Internet experience than ever before. The U.S. Robotics 56K Faxmodem USB modem with V.92 technology offers not only fast downloads but great new features as well. Modem on Hold makes the most of Call Waiting, Caller ID, and voice mail services from your phone company. If you take an incoming call using ICN, the modem "suspends" your online session during your conversation and lets you resume it afterwards without redialing. If you ignore the call, it will be routed automatically to your voice mail. Quick Connect reduces the time it takes to make a connection to your service provider. By "remembering" the line conditions from the previous connection, the modem can bypass portions of its training sequence and get you online faster. V.PCM Upstream allows the modem's upstream communication to reach speeds of up to 48 Kbps. With ControlCenter software, you choose whether to maintain the fastest possible downstream speed or a "balanced" connection of downstream and upstream communication. Even first-time modem users will find the U.S. Robotics 56K Faxmodem USB modem simple to install. All of the necessary fax software and V.92-enabling utilities are included on the Installation CD-ROM.
