FAQs

Q: How is the 2000 tier different from other tiers?
A: Tiers represent model-defined capacity options. Actual session counts vary by codec and topology; consult official sizing guidance.

Q: Will it work alongside onboard PVDM resources?
A: Yes. It augments system DSP resources and can complement onboard or NIM-level PVDM where required.

Q: Do I need to change my IOS XE version?
A: Use an IOS XE release supported by your router and the module. Check the release notes and hardware compatibility list.

Q: What deployment scenarios benefit most?
A: Sites requiring larger transcoding pools, multi-party conferencing, or secure media handling benefit from additional DSP capacity.

Q: Does this module provide physical voice ports?
A: No. It provides DSP resources. Physical voice interfaces come from separate NIMs or other modules.
