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, and secure voice in Cisco Unified Communications Solutions. Features Investment protection & field-upgradable capability The PVDM3 modules all have the same form factor, and are used across Cisco 2900 & 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. They support all codecs that are supported by the PVDM2 modules. High density & 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- & 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 & a higher number of participants per conference than the PVDM2. ...
