The Le79234 Next Generation VoiceEdgeTM Control  
Procesor (VCP) is a second generation platform that  
deliverenhanced call control, self-test and line test  
capabies. This latest processor works with  
Micrsemi NGCC devices using its SPI interface, PCM  
port(s), and GPIO. The Le79234 device provides the  
same integrated line-testing and feature-set as the  
Le79112 device plus additional capabilities such as 4  
channels of simultaneous line testing.
