DESCRIPTION
The VE8910 chipset is an integrated, low-cost 1FXS chipset that is optimized for VoIP
access devices. The chipset implements a complete BORSHT functionality by
providing the necessary voice interface functions to power, ring, signal, and connect
one or more telephones. On the digital side, the VE8910 chipset provides standard MPI
and PCM interfaces to leading VoIP processors. The VE8910 features low power
consumption in all modes of operation; In on-hook Low Power Standby, it typically
draws 50 mW, less than half that of its nearest competitor.
The VE8910 chipset is supported by the Zarlink VoicePath™ API-II (VP API-II) software
package, which enables designers to program a single hardware circuit for worldwide
markets. The VP API-II 'C' code is used to abstract the Zarlink devices from application
code while providing functions for controlling, supervising, and testing a set of
subscriber lines. The Zarlink VeriVoice™ Test Suite software package provides metallic
loop testing based on the Telcordia GR-909 and TIA-1063 recommendations.
