The Cisco Packet Voice Digital Signal Processor Modules (PVDMs) enable the Cisco Catalyst 8000 Edge Platforms Family and the Cisco 4000 Series Integrated Services Routers (ISRs) to provide rich-media capabilities such as high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice for Cisco Unified Communications solutions. These new modules support unprecedented scale while allowing for a smaller solution footprint than ever before.
The Cisco PVDMs are available in three form factors with four supported densities in each form factor:
The motherboard PVDMs are supported on all Cisco 4000 Series ISRs except the ISR 4461. They can be plugged directly into the single slot on the router motherboard or into the Network Interface Module (NIM) that supports T1/E1 ports. A PVDM4 module plugged into the motherboard delivers IP-based voice services such as conferencing, media optimization, and transcoding only.

The PVDM4 modules are supported on all Cisco 4000 Series ISRs except the ISR 4461. The platform motherboard has one slot for the PVDM4 module. You can plug any additional PVDM4 modules into the T1/E1 NIMs.
Note that the 4000 Series ISRs do not support the PVDM3 modules, and the 2900 and 3900 Series ISRs do not support the PVDM4, SM-X-PVDM and NIM-PVDM-X modules.
