Radicom Research Creates Small Modem Module for Home Security

SAN JOSE, Calif – January 16, 2007 – Radicom Research, Inc., a leading designer and manufacturer of dial-up and wireless RF modems for embedded systems applications, introduces the TinyModem™, the world's smallest modem module with an RJ-11 connector.

Measuring just 0.66" (W) x 1.25" (D) x 0.75" (H), the full-featured TinyModem with data, fax and voice capability is easy to integrate into small-footprint designs. Highlights include improved EMC/EMI shielding, built-in data pump, modem controller and on-board International DAA.

The TTL interface TinyModem tolerates high isolation voltage up to 3750V and is fully self-contained. Standard features include caller ID, line-in-use, extension pickup, call-waiting, remote hang-up detection, data rates from 300 to 56 Kbps, 14.4 Kbps fax rate, and voice playback and recording capability.

The TinyModem's miniature dimensions and fast connection is ideal for home security systems intended to instantly report emergency and routine coded signals to a central location. The module delivers a simple but effective approach to data collecting, logging, remote diagnostics and communications. Its ultra low power consumption does not tax resources, and the TinyModem's tight configuration frees up valuable real estate for additional features in more compact designs.

"Radicom researchers developed the TinyModem module at the request of embedded applications designers who wanted the advantages of a built-in RJ-11 phone jack encapsulated in a much smaller package – but without sacrificing any of the features found in our other lines of modem modules," said Alex Tsau, Vice President of Operations for Radicom Research. "The result is a feature-packed modem less than half the size of the competition."

Its small scale, combined with the advantages of a standard RJ-11 connection and improved shielding, simplifies embedding data communications functionality into numerous devices, allowing manufacturers, designers and integrators to move products off the drawing board and into production more quickly.

Summary of Features:

• -40oC to +85oC operating temperature

• RoHS complaint

• Fax / voice playback and recording

• Serial TTL interface

• Single 3.3V supply, 5V tolerant I/O

• Low power consumption and sleep mode support

• Tolerates high isolation voltage up to 3750V

• Enhanced EMC/EMI shielding

• AT command set support

• Up to 56 kbps data speeds downstream

• Generates and detects DTMF tones in voice mode

• Line-in use, remote hang-up, extension pick-up detection

• Automatic format and speed sensing

• Caller ID type I and II for select countries

Agency approvals: Transferable FCC68, CS-03 and CTR21 certified. FCC15B, EN55022B and EN55024 compliant. c/UL, EN60950-1 and EN60601-1 pending. Multiple patents are pending on the TinyModem architecture.

The TinyModem module meets all RoHS compliance directives, and conforms to all standards required for immediate shipping to Europe and around the globe.

Line-in-use and connection detection features allow the modem to share a phone line with other equipment, eliminating the cost of a dedicated phone line, allowing field personnel to check status and receive reports on remote facilities and respond to abnormal conditions immediately.
