Description

CONF

The Le79234 Next Generation VoiceEdge^TMControl

Processor (VCP) is a second generation platform that

delivers enhanced call control, self-test and line test

capabilities. This latest processor works with

Microsemi 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.
