Cisco NIM-PVDM-32= - Network Interface Module

Cisco Part Number: NIM-PVDM-32=  is a NIM PVDM with 32-channel DSP NIM PVDM with 32-channel DSPU, spare

The Cisco NIM-PVDM-32(=) is a Network Interface Module (NIM) Packet Voice Digital Signal Processor Module (PVDM) that provides 32 voice DSP channels. It is designed to be installed in the network interface module slot of compatible Cisco routers. This module supports a range of voice codecs and media-enhancement features, enabling high-density voice connectivity, conferencing, transcoding, and secure voice capabilities for Cisco Unified Communications solutions.

Key details about the NIM-PVDM-32(=) include:

• Channel Capacity:
  • 32 channels for low-complexity voice codecs
  • 24 channels for medium-complexity voice codecs
  • 16 channels for high-complexity voice codecs
• Supported Codecs:
  • Low complexity: Clear channel, G.711, Fax and modem pass-through
  • Medium complexity: G.722, G.726, G.729a, G.729ab, Fax Relay
  • High complexity: G.728, G.729, G.729b, iLBC, Modem relay
• Media-Enhancement Features:
  • Echo cancellation
  • Tone detection
  • Noise reduction
  • Acoustic shock prevention
  • Gain control
• Installation:
  • Installed in the Network Interface Module slot on Cisco ISR 4000 Series and Catalyst 8300 Series Edge Platforms that support NIM modules.
• Use Cases:
  • Provides DSP resources for voice services such as conferencing, transcoding, and media optimization on routers supporting Cisco Unified Communications.

This module is part of a family of NIM-PVDM modules available in different channel densities (32, 64, 128, 256) to scale voice DSP resources according to deployment needs.
