Le79112 VoiceEdge Control Processor

The Le79112 VoiceEdge™ Control Processor (VCP) is a digital signal processing platform that works with the Legerity VE790 series chip sets using the MPI interface, PCM port, and an interrupt line from the codec/filter. The primary functions of the Le79112 VCP are to program and control the codec/filter to implement enhanced call control and test capabilities.
