Solved: VWIC2 versus VWIC3

antoinemeunier · ‎05-21-2012

Hello,

I have a question concerning VWICs and 3945e Voice Routers.

Our customer uses 3945e Voice Routers, and we want to add VWICs in it. Now, part of the box already uses VWIC3-modules, but we still have some VWIC2-modules that we could use.

Can we combine VWIC2 and VWIC3 modules in one VR?
And can we combine PVDM2 and PVDM3?

Thanks a lot,

Best regards,
Antoine

Hi,

Have a look at these links:-

For supported VWICS
http://www.cisco.com/en/US/prod/collateral/routers/ps10538/aag_c07_563807.pdf

DSP (PVDMs)
http://www.cisco.com/en/US/prod/collateral/routers/ps10538/qa_c67_553891_ps10536_Products_Q_and_A_Item.html

Q. Can the PVDM2 and PVDM3 DSP modules coexist on the Cisco 2900 and 3900 Series routers?
A. Yes, they can coexist as long as they are not both installed in the same domain. The motherboard PVDM slots form one domain and each service-module slot forms a separate domain. The motherboard domain can contain either all PVDM2 modules or all PVDM3 modules. A service-module domain can contain only PVDM2 modules housed by the NM-HDV2 carrier card. If a mix of PVDM2s and PVDM3s is detected on the motherboard, the PVDM2s are deactivated, allowing only the PVDM3s to be active. If PVDM2s are detected in service-module slots and PVDM3s are installed on the motherboard, then both continue to function in their own domain and coexist.
