Cisco Module NIM-PVDM-64= : 64-Channel DSP For Voice/Video & High-Density Conferencing In ISR 4000 Routers
The Cisco NIM-PVDM-64= is a Network Interface Module (NIM) with an integrated 64-channel Digital Signal Processor (DSP) designed for Cisco ISR 4000 Series routers. This module enhances voice and video processing, enabling high-performance conferencing, transcoding, and gateway services in enterprise and service provider networks.
Key Features & Benefits
✔ 64-Channel DSP Capacity – Supports high-density voice (G.711, G.729, G.722) and video codecs, ideal for IP telephony, conferencing, and SIP trunking.
✔ Seamless Integration with ISR 4000 – Plugs directly into the router’s NIM slot, eliminating the need for external DSP hardware.
✔ Advanced Voice Quality – Features echo cancellation, packet loss concealment (PLC), and adaptive jitter buffering for superior call clarity.
✔ Video & Conference Bridging – Enables multi-party voice/video conferencing (Meet-Me, ad-hoc bridges) and T.38 fax support.
✔ Optimized for Cisco Collaboration – Works with Cisco Unified Communications Manager (CUCM), CUBE, and Webex solutions.
