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.
