Relation between PRI port and the DSP card

[iptsupport]

Hi , 

I am facing problem with dsp cards . I wnated to know how I can which dsp card handle the calls of the voice port . 

I  want to use this information to know which PRI is affected by the DSP problem . 

I am using cisco 4451 ios  15.4.

Hi,

You can run the command show voice dsp group all to check the dsp status. It should show UP.

Hi,

you can run the below commands in sequence:

first login in the GW

a. term mon

b. debug isdn q931

c. Now place the call.

d. After u place the call, u will find call has gone through port at bottom like se0/0/3:15 with called and calling number

003980: Feb  8 17:43:15.814: ISDN Se0/0/3:15 Q931: TX -> CONNECT_ACK pd = 8  callref = 0x000C

e. Now run the command show voice dsp detailed which will give output as below with DSP NUM

DSP    DSP                 DSPWARE CURR  BOOT                         PAK   TX/RX
TYPE   NUM CH CODEC        VERSION STATE STATE   RST AI VOICEPORT TS ABRT PACK COUNT
====== === == ========= ========== ===== ======= === == ========= == ==== ============
SP2600 001 01 g729r8        36.1.2 busy  idle      0  0 0/0/3:15  31    0    7163/7331

f. Now, u can run the command show voice dsp group all also

dsp 1:
  State: UP, firmware: 36.1.2
  Max signal/voice channel: 43/43
  Max credits: 645, Voice credits: 645, Video credits: 0
  num_of_sig_chnls_allocated: 30
  Transcoding channels allocated: 0
  Group: FLEX_GROUP_VOICE, complexity: FLEX
    Shared credits: 624, reserved credits: 0
    Signaling channels allocated: 30
    Voice channels allocated: 1
    Credits used (rounded-up): 21
    Voice channels:
      Ch01: voice port: 0/0/3:15.31,

Right now I can't proccess calls on this DSP  so I'm looking for somthing like : 

DSP  from slot 1 process calls from voice port 0/0/0 , 0/0/1  . 

DSP  from slot 2 process calls from voice port 0/1/0 , 0/1/1. 

Is it possible ?

No idea, if we can achieve this.

Can u share show version/show diag and show voice dsp detailed from router?

regds,

On the 44xx series routers/gateways, the DSPs for the interfaces are on the interface card. DSPs on the motherboard are purely for conferences/transcoding.
