USB 56K modem for legacy connectivity

The Corn Electronics 43R1815 is an external USB modem that provides a 56Kbps dial-up connection for data, fax and telephone answering. It targets users who must maintain access to analogue telephone lines for point-of-sale terminals, industrial automation or remote management where broadband is unavailable.

V.92 protocol limits throughput to 56Kbps downstream

The V.92 interface caps maximum download speed at 56Kbps and upload at a lower rate dictated by the analogue line. Real-world throughput depends on line quality and distance from the exchange, so sustained speeds are often below the rated maximum. The USB link itself does not constrain performance.

Conexant RD02-D400 chipset determines driver support

The internal Conexant RD02-D400 chipset dictates which operating systems can recognise the modem without additional drivers. The supplier lists compatibility with Windows 2000, XP, 2003, Vista, 7, 8, 8.1 and 2008 in both 32-bit and 64-bit editions. Buyers on newer Windows versions or non-Windows platforms must verify driver availability before purchase.

Questions about this item

Does this single 56Kbps V.92 model cover both home and industrial terminal use?

Yes, the 43R1815 is built for standard home use and for embedded applications such as transaction terminals, interactive clients and industrial automation.

Will the 56Kbps V.92 rating deliver full speed on a typical phone line?

The 56Kbps figure is the maximum downstream rate under V.92; actual throughput depends on line quality and the ISP, and upstream is limited to V.92 limits.

What does the USB interface cap at for this modem?

The USB connection carries the V.92 session at up to 56Kbps downstream and 14400bps fax; the bus itself is not the bottleneck.
