Radicom Research, Inc., a leading designer and manufacturer of dial-up and wireless modems for embedded systems applications, introduces its new line of USB hardware modems.

Available in modular and standalone configurations, these modems process data using their own hardware and do not utilize any processing power of the host computer. These modems are CDC-compliant and are supported by Microsoft CDC modem drivers and Linux CDC-ACM drivers. They work with Linux, Windows and Mac operating systems.

Radicom's standalone V92HU-E modem measures just 1.4"(W) x 2.5"(D) x 1.0"(H) enclosed with USB interface and RJ-11 phone jack. The modular V92HU measures just 1.0"(W) x 1.0"(D) x 0.25"(H) has no on-board jacks, permitting custom jack placement.

Radicom's USB modems contain 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 thus operate reliably when line current is low due to long lines or poor line conditions.

Radicom USB modems have their own built-in DSP (Data Signal Processing), and support V.92 analog data, V.44 data compression, 14.4 kbps fax, and remote telephone answering machines (TAM) without utilizing host-processing power. USB 1.1 and 2.0 host controllers and hubs are supported. They are USB hot swappable and can operate at data rates from 300 to 56K, and accept AT command set.

Compact USB Hardware Modems

"Radicom engineers designed these USB hardware modems at the request of OEM designers who wanted compact USB hardware modems that would work with Linux, Windows and Mac operating systems and have all the features found in larger packages," said Alex Tsau, Vice President of Operations for Radicom Research. "The results are small, low power USB hardware modems that satisfy a wide spectrum of applications."

With international DAA and RoHS compatibility these modems comply with most international standards and are ready to ship to US, Canada, Europe and other major countries.
