NM-HDV DSP Problems...

surenx_cisco

Level 1

Dear Friends

I have a Cisco 3640 with NM-HDV-2E1-60 module with VWIC-2MFT-E1.

The ios image is c3640-js-mz.123-19.bin and version is 12.3

I have a strange problem with the NM-HDV module.

I make the calls then these calls connect and after 2-3 seconds they drop, and the module doesn't free the channel, the channel stays busy...

All the lights on the nm-hdv dsp light up green.

I've tried to test the dsp's issuing the test dsp 0 command and then querying the dsp resource and status and it shows up the following

Dsp firmware version: 4.1.41

Maximum dsp count: 15

On board dsp count: 15

Jukebox available

Total dsp channels available 60

Total dsp channels allocated 60

Total dsp free channels 0

Querying dsp status......

It doesn't show the dsp status...

test dsp 1 (2, 3) commands say that Card 1 (2, 3) is not present.

How can I be 100% that the problem is because of the DSP's (if it is like that)

I'm saying this because I can buy new DSP's and change them, but I need to be 100% sure...

Any reply is appreciated!

The issue could be with the DSPs, but the querying dsp status is not an issue. It is the normal behavior.

Thanks for your reply.

I've done some tests and here's the result.

So it seems that the problem is really in DSPs.....

Have you put DSP resource into Transcode, MTP or Conf usage?

Well the NM-HDV module is connected to a PSTN so my guess, the DSP usage is used for transcoding.
