Zoom Dualmode 56K V90 Modem

The Zoom/FaxModem 56K External Model 2948 is Zoom's classic, award-winning, external fax modem. It plugs into the serial (RS-232C) port of a Windows, Mac OS or Linux-based desktop computer. The Zoom/ FaxModem 56K External Model 2948's performance is further enhanced by its on-board controller and DSP (Digital Signal Processor). The Zoom/FaxModem Model 2948 is capable of receiving data from an Internet Service Provider (ISP) or online service over standard phone lines at speeds up to 56 Kbps uncompressed. Outgoing data is transmitted at speeds up to 33.6 Kbps. The Zoom/FaxModem 56K External Model 2948 is Dualmode, supporting both the V.90 ITU Standard and K56flex, the commonly used pre-standard 56K technology. The modem automatically selects V.90, K56flex, 33.6 Kbps or slower speed to achieve the fastest compatible connection speed. Like all Zoom Dualmode modems, the Zoom Model 2948 includes V.80 capability for compatibility with H.324 standard point-to-point video telephony over regular phone lines. It also supports Group 3, Class 1 Fax. Additional features include Zoom's Channel 2 Call Waiting support which allows selective answering of incoming voice calls during Web browsing. The Channel 2 feature works in conjunction with the Call Waiting service available from most phone companies. It functions with all ISPs (including AOL) and popular browsers. The Model 2948 also features ZoomGuard. ZoomGuard provides superior protection against lightning, the number one cause of modem failure. ZoomGuard is not only better than the "varistor" protection found on other modems, but also outperforms most stand-alone surge protectors. Bundled software includes hardware drivers and utilities plus fax/voice/ data communications, videoconferencing, Internet access, graphics editing and other useful programs.
