Mitel 3300 Alarm DSP failure
« on: December 05, 2013, 01:35:34 PM »
I have an alarm stating DSP failure and the following log.

Dsp resource may not be allocated. Trying non-MIPs loading algorithm

Not sure what this means could someone explain? I know DSP is used to cancel echo but I haven't needed to replace any cards as of yet. This site is having issues with echo and it may be related. 3300 CXi.

Thanks,

If you have allocated more DSP resources then physical available in the controller the system will show an alarm that xx% DSP is faulty as the system can't detect it has any more to fulfill the needed resources. What does your alarm say?

Name=DSP Failure
Alarm Level=Major
Total=4
Unavailable%=25
Minor Threshold=>0
Major Threshold=50

I'm not sure how more DSP resources would get allocated since I have never done this before unless it was by mistake.

In your case the system needs 4 DSP resources while booting to serve the parts you got configured. It's missing 1 as the base system only has two and you probably got 1 T1/E1 card in the system. the total for this is now 3 DSP resources and your config needs more. Have a look at the 6.0 Mitel Engineering Guide Line doc page 50.

Is it worth seeing if a reboot fixes it, or you can tell from the info what is happening?

Yeah, I planned on rebooting it tonight. No, I cannot tell what from the info what's happening. I spoke to my rep today as I thought DSP was helping with echo but not on the CX models only on larger models. I'm not really sure what all this does for the controller on the CX models so hopefully a reboot will resolve it.

To add additional echo cancellor resourses to a MXe you add a DSP II. Think the CX can't expand past the embedded DSP resources so a DSP would be for compression or for T.38

I have had this when i tried to increase the number of voicemail ports on a CX(i)
above the 4 i got a DSP error
Putting it back to 4 removed this error

Unless its a PRI card then you get up to 16 available because that adds resource for voice services which includes voicemail.

For DSP troubleshooting you should know what you have and what you need.
- in Hardware Modules form under Hardware you can see the DSP modules installed
( I just had a problem with an old DSP module installed in a CX II and was not used by the system at all, after upgrading to Rel 6 it generated an alarm, had to remove the card)
- next check your licenses, if you have licenses enabled that require DSP II cards and you don't have it installed you get an alarm (Fax and compression)
- check the number of voice mail ports programmed and max allowed based on your configuration (tech handbook)

If you have a quad DSP and one chip is dead that would equal 25%.
