NIM-PVDM-128 Description
NIM-PVDM-128 is a Cisco voice DSP network interface module in the Cisco Packet Voice Digital Signal Processor Modules portfolio for Catalyst 8300 and supported Catalyst 8200 Series Edge Platforms, built to add branch IP media services such as transcoding, conferencing, and media optimization. Cisco identifies this exact SKU as a Network Interface Module with a 128-channel DSP, lists 96 medium-complexity channels and 64 high-complexity channels for the module, states that NIM-PVDM modules support IP-based voice services rather than TDM applications, rates the module at 15W, and lists NIM-PVDM-128 in the Catalyst 8300 and Catalyst 8200 interfaces catalogs for IOS XE and XE SD-WAN software support.

Application Scenarios
Use NIM-PVDM-128 when a supported branch router needs dedicated DSP resources for IP media services and the design requires the 128-channel low-complexity NIM-PVDM tier.
Select this SKU for Catalyst 8300 designs where the order must keep DSP-farm services available in IOS XE mode or use NIM-PVDM support in XE SD-WAN mode.
Choose NIM-PVDM-128 when NIM-PVDM-64 is below the required codec channel count and NIM-PVDM-256 would exceed the planned DSP density for the router slot.

- In a NIM-PVDM-128 vs NIM-PVDM-64 comparison, the main difference is channel density: NIM-PVDM-128 doubles the listed low-, medium-, and high-complexity channel counts.
- The NIM-PVDM-128 vs NIM-PVDM-256 difference is capacity tier; NIM-PVDM-256 provides twice the listed channel count of NIM-PVDM-128 in the same NIM-PVDM slot family.
- For buyers deciding which model to choose, the NIM-PVDM-128 comparison should start with required codec complexity and DSP channel count, then confirm the router platform and software listing.
Selection Guide
1. Choose the 128-channel NIM tier
Select NIM-PVDM-128 when the voice design needs 128 low-complexity, 96 medium-complexity, or 64 high-complexity channels in a NIM-PVDM form factor.
2. Use lower or higher density only when the channel math changes
Move to NIM-PVDM-64 only when the supported channel count is enough, or select NIM-PVDM-256 when the same NIM-PVDM family must support a larger DSP pool.
3. Keep platform mode in the order review
Check whether the deployment runs IOS XE or XE SD-WAN, because Cisco documents different PVDM module options for Catalyst 8300 IP media services by mode.
4. Do not use it as a TDM DSP substitute
Order NIM-PVDM-128 for IP-based voice services and keep TDM requirements tied to Cisco-documented PVDM4 or voice NIM design guidance.
Ordering Checklist
|
Review Area |
Required Confirmation |
Procurement Risk |
|---|---|---|
|
Exact SKU |
Confirm NIM-PVDM-128 rather than NIM-PVDM-64 or NIM-PVDM-256 |
Avoids ordering the wrong DSP density tier |
|
Codec capacity |
Match the design to 128 low-, 96 medium-, or 64 high-complexity channels |
Prevents under-sizing DSP resources for the required codec mix |
|
Platform family |
Verify the target Cisco router against current Cisco interface-module support pages |
Prevents placing the module into an unsupported chassis or mode |
|
Service type |
Confirm IP media service use rather than TDM application use |
Cisco documents NIM-PVDM-X modules as IP-service DSP options |
