Modem draws ultralow power from USB port

Radicom Research Inc. has introduced a compact USB dongle modem dubbed V92HU-E2 that processes data using its own hardware and does not utilize any processing power of the host computer.

Because it is a hardware modem, the V92HU-E2 dongle modem can be easily adopted in non-x86 CPU and non-Windows OS-based systems. The modem will operate with any system that has a USB CDC (Communication Device Class) driver.

The V92HU-E2 dongle modem measures just 0.55-inch x 0.75-inch x 2.50-inch, weighing less than 1oz, it can be easily tucked away in the smallest of notebook cases and enables consumers to easily connect their notebooks and desktops to the Internet over standard telephone lines.

The USB dongle modem contains a hardware controller, a data pump and an International DAA (Data Access Arrangement). The International DAA in these modems does not draw power from the telephone line, but only draws low power from the USB port. They operate reliably when line current is low due to long lines or poor line conditions.

The modem provides 300bit/s to 56Kbit/s data rates, 14.4Kbit/s fax, on line voice playback and recording, and a hot swappable USB interface. Other features include caller ID, modem-on-hold, caller waiting detection, data/fax/voice call discrimination, quick connect, and extension pickup detection. Modem customization is available through patch code that can be stored in modems on board memory.

The V92HU-E2 is designed to meet global Safety and Electromagnetic Compatibility (EMC) standards, including IEC60950-1 and CE marking. It meets RoHS compliance directives, and conforms to telecom standards required for immediate shipping to the U.S., Canada, Europe and other major industrial countries around the world.

Pricing begins at $49 each. Devices are available now.
