Abstract:

DESCRIPTIONThe VE8911 chipset is a highly integrated, cost-effective 1FXS+1FXO chipset that isoptimized for residential VoIP access devices. The chipset implements a completeBORSCHT functionality by providing the necessary voice interface functions to connectto, 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 providesstandard MPI and PCM interfaces to leading VoIP processors. The VE8911 chipset issupported by the Zarlink VoicePath API-II (VP API-II), which enables designers tooffer a single hardware design that is software programmable for worldwide markets.
