isr 4451 voice configuration

[vijendra Saravanamuthu]

hi anyone has a sample configuration for isr 4451 with regards to voice.  I am trying to configure it for the first time. commands are different. example , enabling network-clock participate  (my t1 is on 0/2)

EQSVAN-GW01(config)#network-clock participate ?
  <0-2>  Select the slot to enable/disable

EQSVAN-GW01(config)#network-clock participate 0
Slot 0 is incapable of participating in network clocking, reason : IOSXE slot 0, subslot 0 does not support network-clock participate
EQSVAN-GW01(config)#network-clock participate 0/2
                                               ^
% Invalid input detected at '^' marker.

EQSVAN-GW01(config)#network-clock participate 2
Slot 2 is incapable of participating in network clocking, reason : IOSXE slot 2, subslot 0 does not support network-clock participate
EQSVAN-GW01(config)#network-clock participate 0 2
                                                ^
% Invalid input detected at '^' marker.

I think I am suppsed to use network-clock synchronization automatic instead.  am I right?

also I have a pvdm4-64 on 0/4.  when I try to configure controller it complains of not enough dsp

EQSVAN-GW01(config)#controller t1 0/2/0
EQSVAN-GW01(config-controller)#pri-group timeslots 1-24 service mgcp
% Not enough DSP resources available to configure pri-group on controller T1 0/2/0
% The remaining dsp resources are enough for 0 time slots.
EQSVAN-GW01(config-controller)#
*May 15 16:35:31.253: %XCCTSP_VOICE-3-NOSDB: No signaling data block is available to build the
        voice interface(0/0:23) or DSP may not be present

*May 15 16:35:33.134: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/2/0:4, changed state to down
 

this is why I would appreciate a sample voice configuration. 

much appreciated.

Hi Vijay,

Kindly check out these documents.

If you have any problem, let me know.

Hi,

I suppose you need to configure codec complexity command for channel density under voice-card.

can u share show inventory from router?

Vijay,

I ran into this same issue configuring a new 4351 router.  Here is how I resolved the slipped seconds:

controller T1 0/1/1
 clock source line primary

network-clock synchronization automatic
network-clock input-source 1 controller T1 0/1/1

Then if you type:

 show network-clocks synchronization

 Interface            SigType     Mode/QL      Prio  QL_IN  ESMC Tx  ESMC Rx
 Internal             NA          NA/Dis       251   QL-SEC    NA        NA
*T1 0/1/1             NA          NA/Dis       1     QL-SEC    NA        NA

You will see your T1 interface with the sync *.  

Hope this helps.

[+5] to Anthony for sharing the resolution.

I have this exact same problem on a 4321.

I've tried the above resolution but still nothing 

PLEASE help?

NA - Not Applicable

hi,

you should install the dsp chip onto the pri network card. DSP comes installed on slot 0. so open up the box, uninstall the dsp and install it on top of the PRI card. 

then configure.

Thanks that worked

Thanks Anthony, your solution fixed our slip seconds as well!

controller T1 0/1/1
 clock source line primary

network-clock synchronization automatic
network-clock input-source 1 controller T1 0/1/1

This worked for me also thank you for the tip
