The Rhino R24FXO-EC is “ready to roll” with two incredible feature differentiations over our competition - our on-board control element, and our on-board Echo Cancellation circuit. The control element eliminates PCI bus “bit banging”, which means that the R24FXO-EC requires less CPU power, and more Rhino cards can be used in one computer over alternative, antiquated solutions. The Echo Cancellation circuit provides echo protection no matter what, to ensure that calls are clear, crisp and echo free.

Rhino Equipment Corp. offers you a complete line of low cost PCI plug-in cards including Single T1/E1, Dual T1/E1, Quad T1/E1, Quad FXO analog, Octal FXS/FXO and 24-port analog fixed and mixed mode analog interfaces. And don’t forget the full line of Rhino Channel Bank products, for large scale analog FXS or FXO applications.
