* 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). USRobotics modems featuring V.92 enhancements are backward compatible and will negotiate the highest possible speed when connecting to an ISP.
† Advanced fax functionality may require installation of bundled software.§ Time measured from start of modem tones, amount of time may be slightly longer with error control enabled.‡ Caller ID and distinctive ring require service from your local phone company. Caller ID may not be supported in some countries
