DESCRIPTION
The Le79114 VoiceEdge™ Control Processor II (VCP II) is a
second generation platform that delivers enhanced call control,
self-test and line test capabilities. This latest processor works
with Zarlink Ve790 devices using its SPI interface(s), PCM
port(s), and GPIO. The Le79114 VCP II device provides the
same integrated line-testing and feature-set as the Le79112
VCP device, plus additional capabilities such as 32 channels of
simultaneous DTMF detection and 64 channels of improved
POTS control.
This product enables the design of a low-cost, high-
performance, fully software programmable line interface for
multiple country applications. All AC, DC, signaling parameters
and data are fully programmable. The integrated test capability
is crucial for remote applications where dedicated test
hardware is not cost-effective.
The Le79114 device is provided with extensive software and
support, through the LineCare™ software suite, enabling the
designer to develop a fully programmable solution in the least
amount of time.
