ATM IMA problem on 3825 router

I am upgrading the router hardware from a 3620 to a 3825 router. I am running ATM IMA with 4 T1 bundle. The existing router (3620) has been running fine, but when I switch to the new router 3825, I can't bring up the ATM interfaces (the 4 T1). But when i switch back to the old router, it works fine.

The config basically is identical between the two.

I am puzzle what went wrong. is the ATM service provider need to do anything on their end?

Any suggestion on this would be greatly appreciated.

Check the clocking if they are configured.

I configured this as follows:

network-clock-participate wic 0

network-clock-participate wic 1

network-clock-participate wic 2

network-clock-participate aim 0

network-clock-select 1 T1 0/0/0

network-clock-select 2 T1 0/0/1

network-clock-select 3 T1 0/1/0

network-clock-select 4 T1 0/1/1

Re: ATM IMA problem on 3825 router

it turns out to be the service provider has to re-provision their circuit on their ATM switches. After that, all works well.

Thanks all your help.
