Radicom USB Modems
Radicom Research, Inc. rolled out a new line of USB hardware modems. The new modems are available in modular and standalone configurations. The modems process data using their own hardware and do not utilize any processing power of the host computer. The new 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 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. As a result, they 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.
Digital Line Guard automatically detects an over current on tip and ring lines and protects the modem from over current that might result from an accidental connection to a digital telephone line. 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.
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 Research's standalone and modular USB modems are available now. Prices begin at US$49.00 in quantities of 1,000 or more.
