Footnotes
* Capable of receiving at up to 56 Kbps and sending at up to 48 Kbps (or 31.2 Kbps with V.90 server). Due to FCC regulations on power output, receiving speeds are limited to 53.3 Kbps. Actual speeds may vary. V.92 and V.90 features require compatible phone service and support from your Internet Service Provider (ISP). USR modems featuring V.92 enhancements are backward compatible and will negotiate the highest possible speed when connecting to an ISP.
** Support for 64 bit operating systems requires a driver update (available in the support section of this website). Support for newer Operating Systems may also be available.
