The Cisco fourth-generation Packet Voice Digital Signal Processor Module (PVDM4) enables Cisco 4451-X Integrated Services Routers (ISRs) to provide rich-media capabilities such as high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice in Cisco Unified Communications Solutions.
The PVDM4 modules are supported on the Cisco 4451-X platform. You can plug them directly into the single slot on the router motherboard or onto the network interface module (NIM) that supports T1/E1 ports. Enhanced DSP architecture accommodates a packet-processing engine optimized for rich-media voice applications, while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework.
A PVDM4 module plugged onto the motherboard delivers IP-based voice services such as conferencing, media optimization, and transcoding. A PVDM4 module plugged onto the NIM daughter card would be used for voice T1/E1 connectivity.
All the PVDM4 modules have the same form factor and are field-upgradable to allow you to easily scale your voice deployments.
