The Le79234 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, PCM port(s) and GPIO. The Le79234 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.

• Aggregated call control lowers demand on host micro-processor
• 32 channels of call control
• Provides expanded line and circuit testing in conjunction with the NGCC chipset
• Provides 4 channels of simultaneous line testing
• Software interface using VoicePath API-II
• Software downloadable, field upgradeable, expandable
• Serial and parallel host controller interface options
• Complete control of up to 4 Octal NGSLAC (Le79238) devices
• Two slave PCM highway ports
• Single or dual PCM highways capable of operating up to 16.384 MHz
• Separate test highway option
• Internal PLL and hardware network timing  recovery for creating analog sampling clocks
• 3.3 V compliant I/O; Internal 3.3 V to 1.8 V linear regulator for the core logic
