DSP usage

[Alan Couto]

Hello friends,

Do anyone know if we have any command to see the quantity or if possible percent of the DSP usage at a CME router? Like the quantity of dsp resource available...

Thanks,

Alan

You can issue

sh voice dsp group all

And see the usage of each DSP

Hello Java, thank you for replying...

At this moment I have one call running and making xcode to G723..

Can you please help me to understand this log? My router has a PVDM3-256 and I can't see how many I still have available or how many is in use...

It seems that the line with major changes is this one:

Ch01: voice port: 0/0/2, codec: g711ulaw, credits allocated: 15

But show me credits, not channels..

see below

Alan,

I wrote a document on understanding the output of this command..Have a look here..you will understand whats going on

https://supportforums.cisco.com/docs/DOC-29151

DSPs are designed based on provisioned credits. Each dsp is equipped with a certain amount of credits based on the type os DSP it is. These credits in combination with the dsp complexity determine the amount of channels a dsp can support.

Each media operation, such as voice termination, transcoding, and so forth, is assigned a cost in terms of credits. As DSP resources are allocated for a media processing function, its cost value is subtracted from the available credits. A DSP module runs out of capacity when the available credits run out and are no longer sufficient for the requested operation.
