dspfarm transcoding shutdown

[Harald Roessler]

Hi all,

i have a problem with the CISCO2921/K9 Voicegateway. I try to configure a dsp transcoding profile but this always shutdown automatically. I do "no shut" and on the next "sh run" this profile is shutdown.

Do you have any ideas? See some configs and show details below.

Hi Stephan.

It seems there is something wrong with your dsp resources.

Number of Resources Out of Service :4  it should be zero.

 Number of Resources Out of Service : 4

 Number of Resources Out of Service : 4

Run command "sh dspfarm dsp all"  and show us output

Yes,it seems you've not enough dsp recources.

You can try decrease number of xcode sessions from 5 to 1 and no shut.

You can check DSP quanity you need here

Hope it helps also

Hi Stephen,

It may be that you are running low on the Codecs, I guess you are oversubscribing it unintentionally.

Just wondering if you could post, show inventory output as well, just wanted to make sure how many DSPs you have in total.

Secondly are you really using G.729br8, G.729ar8 and G.729abr8 codecs? I usually use only the G.729r8 codecs along with G.711ulaw / G.711alaw codecs

thx for your reply.

we've 2 DSP modules inside.

NAME: "PVDM3 DSP DIMM with 32 Channels on Slot 0 SubSlot 4", DESCR: "PVDM3 DSP DIMM with 32 Channels"
PID: PVDM3-32          , VID: V01 , SN: FOC19070G6L

NAME: "PVDM3 DSP DIMM with 32 Channels on Slot 0 SubSlot 5", DESCR: "PVDM3 DSP DIMM with 32 Channels"
PID: PVDM3-32          , VID: V01 , SN: FOC19102QTQ

i'm a beginner in this voicegateway things. u think its better to use only G.711 codecs?
