Module for Cisco Unified Communications
Product Overview
The PVDM3 brings new rich-media capabilities to Cisco
®
Unified Communications Solutions. High-density voice
connectivity. Conferencing, transcoding, and transrating. Management of voice quality. Power savings, secure
voice, and more. The module resides on the Cisco 2900 and 3900 Series routers to enable these capabilities.
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. The modules have
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 Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) is supported on all Cisco 2900
and 3900 Series platforms, part of the Cisco Integrated Services Routers Generation 2 (ISR G2) portfolio.
It 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 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 (ISRs). 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.
