USB Modems - Standalone
Both the V92MB-U-E and V92HU-E2 (Dongle) are V.92 compliant providing a plethora of features including data speeds from 300 bps to 56k bps, 14.4k bps fax, on line voice playback and record as well as DTMF Decoding and Generation. In that regard, these modems can be provisioned as an answering machine and can generate and follow DTMF commands in both Answer and Dial Out applications. Both modems are 1.1 / 2.0 USB compatible.
This rugged family features a hardware-based modem controller with a built in digital signal processor (DSP). They utilize industry standard AT commands and unlike software based USB (SOFT) modems, the modems manage all modem functionality internally without utilizing your CPU system resources. These modems offer Global Telecom compliances including: FCC Pt. 68 and Pt. 15(USA) Can/CSA, and CTR21(EU).
Other features of this fine family include Caller ID, Modem-on-Hold, Caller Waiting Detection, Data/Fax/Voice Call Discrimination and Extension Pickup Detection. Both the V92MB-U-E and V92HU-E2 (Dongle) meet RoHS compliance directives, and conforms to all standards required for immediate shipping to US, Canada, Europe and most other major industrialized countries around the world.
Radicom Research, Inc. also provides many other embedded modems with Serial TTL interfacing for medical applications. More details can be seen at our web site www.radi.com or contact us directly at sales@radi.com or (408) 383-9006 x112
