High-Density 128-Channel DSP & Voice/Video Processing - Cisco
Module For ISR G2 Routers
The Cisco NIM-PVDM-128= is a high-performance Packet Voice DSP
Module (PVDM) designed for Cisco ISR G2 routers (4000 series) and
compatible platforms. This module delivers 128-channel digital
signal processing (DSP) capacity, enabling advanced voice/video
transcoding, conferencing, and secure real-time communication in
enterprise and service provider networks.
Key Features & Benefits
✔ High-Density DSP Processing – Supports 128 concurrent channels
for voice/video compression, transcoding (G.711, G.729, G.722,
iLBC), and conferencing.
✔ Flexible Deployment – Fits into NIM slots on ISR G2 routers,
saving motherboard space while scaling DSP resources.
✔ Seamless Cisco UC Integration – Works with Cisco Unified
Communications Manager (CUCM), CUBE (Session Border Controller),
and IOS/XE.
✔ Optimized for VoIP & Video – Reduces bandwidth usage with
efficient codecs while maintaining call quality.
✔ Enterprise-Grade Reliability – Cisco-validated hardware for
mission-critical deployments.
