描述 Description

The ZL79124 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 interface(s), PCM port(s) and GPIO. The ZL79124 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 72 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 ZL79124 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.
