The chipset implements a complete BORSHT functionality by providing the necessary voice interface functions to power, ring, signal, and connect 1 16 TIP RING one or more telephones. On the digital side, the VE8910 chipset provides standard MPI 2 15 VBAT RSVD and PCM interfaces to leading VoIP processors. The VE8910 features low power BGND 3 14 RSVD consumption in all modes of operation In on-hook Low Power Standby, it typically VCC 4 13 AGND Le89810 SLIC draws 50 mW, less than half that of its nearest competitor. SOIC-16 (Wide) 5 12 RSN RSVD The VE8910 chipset is supported by the Microsemi VoicePath API-II 6 11 LSN IBR (VP API-II) software package, which enables designers to program a single hardware VREF 7 10 IBT circuit for worldwide markets. The VP API-II C code is used to abstract the Microsemi IBI 8 9 TFLT devices from application code while providing functions for controlling, supervising, and testing a set of subscriber lines. The Microsemi VeriVoice Test Suite software package provides metallic loop testing based on the Telcordia GR-909 and TIA-1063 recommendations.
