Description
AI
The Le79124 Next Generation VoiceEdge™ Control Processor (VCP) is a second generation platform that delivers enhanced call control, self-test and line test capabilities. This latest processor works with the NGCC devices using its SPI interface(s), PCM port(s), and GPIO. The Le79124 device provides 4 channels of simultaneous line testing and 72 channels of improved POTS control.
This product enables the design of a low-cost, high performance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable.
The Le79124 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.
