Data Sheet
High-Density Packet Voice Video Digital Signal Processor Module for
Cisco Unified Communications
Product Overview
®
The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) enables Cisco 2900 and
3900 Series Integrated Services Routers Generation 2 (ISR G2) to provide rich-media capabilities such as
high-density voice video connectivity, conferencing, transcoding, transrating, and secure voice in Cisco
Unified Communications Solutions.
The next-generation high-density packet voice digital-signal-processor (DSP) modules are available in six densities:
PVDM3-16, PVDM3-32, PVDM3-64, PVDM3-128, PVDM3-192, and PVDM3-256, with 16, 32, 64, 128, 192, and 256
channels, respectively (Figure 1). Tables 1 and 2 show the number of voice channels and codecs that each PVDM3
module supports.

Features and Benefits
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 a new 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.
Investment Protection and Field-Upgradable Capability
You can now choose a DSP module ranging from 16 to 256 G.711 channels 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.
In addition, DSPs on the PVDM3 provide more processing power and memory than the DSPs on the PVDM2. The
high performance of PVDM3 supports future voice and video growth with a simple image upgrade to eliminate
complete system upgrades. The PVDM3 modules can not only meet your needs today but also anticipate your needs
in the future.
