Questions & Answers
What is the Cisco NIM-PVDM-128 module?
The Cisco Network Interface Module PVDM-128 is a pluggable DSP module for Cisco routers, providing up to 128 voice/video channels of digital signal processing capacity in a single slot.
Which routers support the NIM-PVDM-128?
The NIM-PVDM-128 is supported on Cisco ISR G2 series (2900/3900) and ISR 4000 series routers with a dedicated NIM slot and the required IOS image.
How many voice channels does the NIM-PVDM-128 support?
It supports up to 128 concurrent voice channels using G.711, G.729, G.722, or G.726 codecs for high-density voice deployments.
Can the NIM-PVDM-128 handle conferencing and transcoding?
Yes, the NIM-PVDM-128 provides DSP resources for hardware-based conferencing, transcoding, packetization, and echo cancellation.
What licensing is required for the NIM-PVDM-128?
The NIM-PVDM-128 requires a valid Cisco IOS software license for voice features and an active Cisco SMARTnet contract for hardware support.
How do I install the NIM-PVDM-128 in my router?
To install, power off the router, insert the module into an available NIM slot, secure with screws, power on, and verify with the 'show platform hardware capacity dsp' command.
Which voice codecs are supported on the NIM-PVDM-128?
Supported codecs include G.711 µ-law/A-law, G.729a/b, G.722 wideband, G.726, Ilbc, and T.38 fax relay for flexible voice and fax applications.
How do I verify module functionality?
Use Cisco IOS commands like 'show voice dsp all', 'show platform hardware capacity dsp', and 'show running-config voice dspfarm' to confirm module status and channel usage.
Can I mix PVDM-128 with other PVDM modules?
Yes, routers that support mixed PVDM populations allow you to install PVDM-128 alongside PVDM-16 or PVDM-64, respecting total DSP capacity limits.
What power and cooling requirements apply?
The NIM-PVDM-128 draws approximately 15W. Ensure your router power supply and chassis cooling meet or exceed Cisco’s published specifications.
Is the NIM-PVDM-128 heat-dissipation compliant?
Yes, the module is designed to meet Cisco’s thermal limits for NIM slots when installed in supported ISR platforms under specified operating conditions.
Does the NIM-PVDM-128 support high-definition voice?
Yes, with G.722 wideband codec support, the module delivers HD voice quality for clearer audio in voice and conferencing applications.
What are typical use cases for the NIM-PVDM-128?
Common use cases include enterprise telephony gateways, video conferencing transcoding, contact center DSP farms, and remote office voice aggregation.
How do I upgrade firmware on the NIM-PVDM-128?
Firmware upgrades are integrated into the Cisco IOS image. Update your router’s IOS to a version that includes the latest DSP feature set.
What diagnostics are available for troubleshooting?
Cisco IOS offers 'test voice dspfarm' commands, event logging, and DSP trace capabilities to isolate issues in voice processing and resource allocation.
Where can I obtain technical support and documentation?
Access the Cisco Support Portal for configuration guides, data sheets, and TAC case submission. Ensure your SMARTnet contract is active for assistance.
