Question

Which Cisco packet voice and video digital signal processor 3 can be used for video mixing on a Cisco Integrated Router Generation 2?

Answers

Explanations

A. B. C. D.

D.

All the PVDM3 types (that is, PVDM3-16, PVDM3-32, PVDM3-64, PVDM3-128, PVDM3-192, and PVDM3-256) support switched-only video conferences.

Only PVDM3-128 and higher modules support video conferencing with video mixing, transcoding and transrating.

The correct answer is B. PVDM3-32.

Digital Signal Processors (DSPs) are hardware components used to manage voice and video signals in Cisco's Collaboration solution. PVDM3 modules are the third-generation DSP modules designed to support voice and video applications. These modules are used on Cisco Integrated Services Routers Generation 2 (ISR G2).

In the case of video mixing, the PVDM3-32 is the right module to use. This DSP module can support up to 32 channels of video and can mix up to 4 video inputs. This capability is achieved through the Cisco Video Conferencing DSP Resource Allocation Manager (VRAM), which manages the DSP resources used by the video conferencing application.

The other options listed are:

A. PVDM3-16: This module can support up to 16 channels of video but cannot be used for video mixing.

C. PVDM3-64: This module can support up to 64 channels of video, but it is not designed for video mixing.

D. PVDM3-128: This module can support up to 128 channels of video, but it is not designed for video mixing.

In summary, the PVDM3-32 is the DSP module designed for video mixing on Cisco Integrated Services Routers Generation 2.
