™ VE890 Series Voice Solution APPLICATIONS Residential and SOHO VoIP CPE, such as ADSL2+/VDSL2 Integrated Access Devices (IADs), Analog Telephone Adapters (ATAs), and VoIP Gateways DESCRIPTION The VE8911 chipset is a highly integrated, cost-effective 1FXS+1FXO chipset that is optimized for residential VoIP access devices. The chipset implements a complete BORSCHT functionality by providing the necessary voice interface functions to connect to, and power, one or more telephones and an isolated Direct Access Arrangement (DAA) for connection to the PSTN. On the digital side, the VE8911 chipset provides standard MPI and PCM interfaces to leading VoIP processors. The VE8911 chipset is supported by the Zarlink VoicePath™ API-II™ (VP API-II), which enables designers to offer a single hardware design that is software programmable for worldwide markets.
