Transcoding resource configuration in ISR4351 router.

Hi,

We are planning to install a 4351 ISR gateway in our contact center setup (UCCE) to support 450 simultaneous G729 ( medium complexity) calls with the following PVDM's and T1 cards.

  • PVDM4-64                :64-channel DSP module
  • SM-X-PVDM-500     : Up to 768-channel DSP module for 4xxx family
  • NIM-8MFT-T1/E1     :8 port Multiflex Trunk Voice/Clear-channel Data T1/E1 Module
  • PVDM4-256             :256-channel DSP module
  • NIM-4MFT-T1/E1     :4 port Multiflex Trunk Voice/Clear-channel Data T1/E1 Module
  • PVDM4-128             : 128-channel DSP module
  • NIM-4MFT-T1/E1     :4 port Multiflex Trunk Voice/Clear-channel Data T1/E1 Module
  • PVDM4-128             :128-channel DSP module

I get 48 medium complexity channels from PVDM4-64 ad 384 channels from the SM PVDM, so it falls short of 18 medium complexity channels to support total 450 simultaneous calls.My query is whether we can configure a single transcoding pool combining the resources on inbuilt PVDM on motherboard (PVDM4-64), PVDM  on Service Module and the leftover channels in the NIM cards together to get the 450 medium channel support.

Thanks in advance!

Thanks and Regards,

Thammaya Gupta K.

Did you ever get an answer to this? 


Can we pool resources from the NIM PVDM-4 and the on-board ISC PVDM-4 together?
