LE79128
Next Generation Carrier Chipset (NGCC)
Overview
We are transitioning to Microchip; this page will be directed to Le79128 product page at www.microchip.com.
| The Le79128 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 Microsemi NGCC devices using its SPI interfaces, PCM ports, and GPIO. The Le79128 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 and 128 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 Le79128 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. |
