PVDM3-128 Cisco PVDM3-128 128-Channel High-Density Voice and Video DSP Module

The PVDM3-128 is a high-density voice and video digital signal processor module designed to expand the media processing capacity of Cisco 2901 and 2911 Integrated Services Routers. It handles voice and video calls by providing the necessary processing power for a large number of simultaneous sessions.

Built for environments where robust voice and video services are needed, this module is often found in medium-sized branch offices and enterprise networks. Network administrators and engineers who require scalable voice infrastructure typically deploy this module to improve call capacity and media handling.

Key Features

• Supports up to 128 voice and video channels simultaneously
• Optimized for Cisco ISR 2901 and 2911 routers
• Enables advanced voice processing functions such as transcoding and conferencing
• Reduces the need for additional hardware by integrating media processing into the router
• Maintains call quality with efficient DSP resource allocation

This module is commonly installed in branch offices where multiple voice calls and video sessions occur concurrently. It helps deliver consistent communication performance without requiring separate voice gateways, simplifying the network setup.

By integrating media processing directly into the router, it streamlines deployment and reduces equipment overhead, making it a reliable choice for businesses balancing capacity and infrastructure complexity.
