The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) enables Cisco 2900 & 3900 Series Integrated Services Routers Generation 2 to provide rich-media capabilities such as high-density voice video connectivity, conferencing, transcoding, transrating, & secure voice in Cisco Unified Communications Solutions. The PVDM3 provides higher density & more processing power than the PVDM2, making the addition of rich-media applications possible. Enhanced DSP architecture accommodates a packet-processing engine optimized for rich-media voice & video applications, while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework used by the PVDM2.
