Description
CONF
The Le79234 Next Generation VoiceEdgeTM Control
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.
