The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) is designed for use with Cisco 2900 and 3900 Series Integrated Services Routers Generation 2. This module enables rich-media capabilities, including high-density voice and video connectivity, conferencing, transcoding, transrating, and secure voice within Cisco Unified Communications Solutions. The PVDM3 offers greater density and processing power compared to its predecessor, the PVDM2, allowing for the integration of advanced rich-media applications. Its enhanced DSP architecture is optimized for both voice and video applications, while still supporting the time-division multiplexing IP (TDM-IP) voice framework used by the PVDM2.
