The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) enables Cisco 2900 and 3900 Series Integrated Services Routers Generation 2 to provide rich-media capabilities such as high-density voice video connectivity, conferencing, transcoding, transrating, and secure voice in Cisco Unified Communications Solutions.

The PVDM3s are supported on all Cisco 2900 and 3900 Series platforms. The PVDM3 provides higher density and more processing power than the PVDM2, making the addition of rich-media applications possible. Enhanced DSP architecture accommodates an original packet-processing engine optimized for rich-media voice and video applications, while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework used by the PVDM2.

PRODUCT FEATURES
Investment protection and field-upgradable capability
You can now choose a DSP module from the PVDM3 module portfolio. The PVDM3 modules all have the same form factor, and are used across Cisco 2900 and 3900 Series Integrated Services Routers. The field-upgradable capability can help you easily scale your voice deployments.
Wide range of CODEC support
The PVDM3 modules support a wide range of codecs of different complexities.
High density and flexibility
The PVDM3 module portfolio has up to 4 times higher density than those in the PVDM2 portfolio. In addition, the PVDM3 modules provide better density for medium- and high-complexity codecs than their equivalent PVDM2 peers.
Conferencing, transcoding, and transrating services
The PVDM3 modules support digital voice connections, analog voice connections, conferencing, and universal transcoding services. The same DSPs on the PVDM3 modules can now support all the services with a single DSP image. In addition, the PVDM3 supports a higher number of conference sessions and a higher number of participants per conference than the PVDM2.
