Modems do not drain computer resources

Radicom's USB modems contain a hardware controller, a data pump and an International DAA

Radicom Research has released its new line of USB hardware modems. Available in modular and stand-alone configurations, these modems process data using their own hardware and do not use 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 stand-alone V92HU-E modem measures 36 x 64 x 25mm, enclosed with USB interface and RJ-11 phone jack.

The modular V92HU measures 36 x 25 x 6mm and 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 analogue data, V.44 data compression, 14.4kbps fax, and remote telephone answering machines (TAM) without using 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 56Kbyte, and accept AT command set.

'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.

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 USB hardware modems are suitable for design into compact systems such as medical devices, POS (point of sale) terminals, gaming devices, vending machines, remote monitoring and data collection systems, industrial monitoring systems, home security networks, handheld computers, back-up communication systems, and any small footprint device that needs to communicate reliably with low power consumption.
