## Long description

The Cisco PVDM4-32 is a voice network module for Cisco 4000 Series Integrated Services Routers. It provides digital signal processing resources to enable high-density voice connectivity, conferencing, universal transcoding, transrating, media optimization, and secure voice features when used with Cisco Unified Communications solutions and Cisco IOS software. The module supports energy-saving modes to reduce power consumption when idle and is designed for use in routers such as the Cisco 4331, 4351, and 4451.
Advantages
The PVDM4-32 delivers scalable voice-processing capacity in a compact module that reduces the overall solution footprint. It enables packetization of T1/E1 digital voice, supports ad hoc and meet-me conferencing with multiple codecs, and performs universal transcoding and transrating between different codec formats and packetization periods. The module also provides voice-quality management functions including compression, voice-activity detection, jitter management, and echo cancellation with ITU-T G.168 compliance. Built-in power-saving modes allow the module to reduce energy use when not active.
Suitable for
High-density digital voice packetization for T1/E1 connections
Conferencing (ad hoc and meet-me) integrated with Cisco Unified Communications Manager
Universal transcoding between different codecs
Transrating between networks with different packetization periods
Voice-quality management and echo cancellation in branch or central routers
Key specifications
Module type: PVDM4 voice DSP module for Cisco 4000 Series routers

Voice-quality features: compression, voice-activity detection, jitter management, echo cancellation (ITU-T G.168, 128 ms tail)
Power: multiple power-saving modes with up to approximately 5 W savings per module in power-saver mode
Physical dimensions: approximately 51 mm (W) × 67 mm (D) × 17 mm (H)
How to use
Install the PVDM4-32 into a supported Cisco 4000 Series ISR voice module slot following the router hardware installation guidelines. Configure voice services and codecs via Cisco IOS Software or Cisco Unified Communications Manager as required by your deployment. Use the router’s configuration interface to allocate DSP resources for conferencing, transcoding, and packetization tasks and enable power-saving modes if desired.
Usage recommendations
Use the PVDM4-32 in compatible Cisco 4000 Series routers (for example 4331, 4351, 4451) and pair it with the appropriate analog or digital interface modules for T1/E1 or FXO/FXS connections. For deployments requiring large conferencing or transcoding capacity, verify available DSP resources per router and configure codec and packetization settings in Cisco IOS or Unified Communications Manager to match network requirements.
