The new and improved version of the Cisco Voice PVDM DSP calculator includes all the recent changes that we have introduced to the enterprise voice segment.

 

The tool is developed to assist in estimating the digital signal processor (DSP) resources needed for T1/E1 Calls & IP Voice services on supported ISR 4000 & Catalyst 8000 platforms which helps in identifying the appropriate voice DSP modules based on the platform selection and DSP session sizing requirement.

What's New

The major highlights of this revised tool include:

  • Autonomous and Controller mode(SD-WAN) 
  • NIM-PVDM DSP Voice Module
  • Opus Codec Transcoding
  • ISR 4461
  • Catalyst 8300/8200 Edge platforms

 

How it Works

With the new UI, the workflow has been enhanced to capture additional options. To discover what's the right voice module for your design, the following details must be fed while navigating through different options on the tool.

1. Platform, Mode & Software (Mandatory): Select the platform family, platform, IOS XE mode & release from the drop-down list.

 

2. Network Interface Card Selection(Optional): If T1/E1 Voice calls are required, select the correct module and number of channels.

 

3. Transcoding & Conferencing sessions: Feed in the number of transcoding or conferencing sessions required.

 

Based on the options selected and session requirements fed into the tool, it results in the module selection option that must be procured in order to meet the DSP requirement.

@Lokesh Kumar Lal Thanks for this new calculator.

 

Can you help me understand why, when selecting 4400 series, I have to select between IOS XE 16.9 & Above -or- IOS XE 17.6.1 ?

 

What does 17.6.1 do differently?

 

Thanks!

Is it the introduction of the VHC(G.711-Opus) option?
