Device Overview

Summary

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 Microchip 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.

High Density Chip Set:
Voice Control Processor (VCP) + Octal SLAC (codec) + Long Loop SLICs
Le79124 (72 Ch.) + Le792388 (codec) / ZL792588 (code with external/ internal ringing)  + Le79271 (SLIC) / Le79272 (Dual SLIC)
Le79128 (128 Ch.) + Le792388 (codec) / ZL792588 (code with external/ internal ringing) + Le79271 (SLIC) / Le79272 (Dual SLIC)

LineCare Test Software - Available Under Documents

LineCare software package for Next Generation VoiceEdge Control Processor (NGVCP) is a complete software solution that aggregates control of Voice Termination Devices (VTDs) to provide a simplified programming interface. The software package provides a set of functions additional to the feature set of the underlying VTDs. It significantly reduces the product development cycle and time-to-market
