Voice using NIM-2BRI-NT/TE on ISR4321 IOS XE Software, Version 16.06.03

We have a new router (ISR4321 XE) with NIM-2BRI-NT/TE for voice, and we are unable to configure the BRI NIM card. Cisco website recommends a minimum IOS level for this hardware was 16.6.1. We upgraded the router to 16.6.3 , and it's still not working. Perhaps a higher version (say 17.x.x) is necessary for this hardware combination? Unfortunately, we don't have test environment to do further research. Your expertise on this matter is very much appreciated.

Hello,

 

as far as I recall, you need to configure the T1/E1 controller with 'clock source internal'...

With PRI NIM, we do need to configure the T1/E1 controller with 'clock source internal'. Unfortunately, this router has no such. Thanks for the response.

Hello,

 

my bad, you are right...BRI not PRI. 

Can you try and install the card in subslot 1, so the config looks like:

 

RouterABC(config)#interface bri0/1/0:

My friend I have the same exact problem.

I've configured many NIM-2BRI cards in 4321 with success but in 4331 the same commands can't make the card work.

I've tried different other commands with no success.

If anyone knows something useful for this to work please share it with us.

Do you have DSP resources in your 4331 ?

 

I recently struggeled a few hours getting ISDN PRI (E1) working on the 4331.

Found that I had to install the DSP module on the E1 card (moved from motherboard).

I am however not sure of the DSP install requirements for BRI on the ISR 4000.
