RCV56HCF PCI/CardBus Modem Designer’s Guide Speakerphone Mode (ISDN and SP Models) The speakerphone mode features an advanced proprietary speakerphone algorithm which supports full-duplex voice conversation with both acoustic and line echo cancellation. Parameters are constantly adjusted to maintain stability with automatic fallback from full-duplex to pseudo-duplex operation. The speakerphone algorithm allows position independent placement of microphone and speaker. The speakerphone mode provid
