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. Figure 1. PVDM3 Family View 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. © 2009-2010 Cisco and/or its affiliates. All rights reserved.

Data Sheet Voice-Quality Management The PVDM3 modules perform compression, voice-activity-detection, jitter-management, and echo-cancellation functions. The echo cancellation offered in the PVDM3 modules has a tail length of 128 milliseconds (ms) and complies with ITU-T G.168. Energy-Saving Feature The PVDM3 DSPs offer multiple power-saving modes, including a power-saver mode when the module is not in use. In power-saver mode each PVDM3 can save up to 5 watts of power.
