1. DESCRIPTION

The LE79128KVCT 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 interfaces, PCM ports, and GPIO. The Le79128 device provides the same integrated line-testing and feature-set as the LE79128KVCT 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, highperformance, 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.
