Grouping multiple ds0's from multiple T1 trunk

AS5400-HPX and multiple TDM carriers entering my VoIP network via CT3. I know that using trunk grouping feature I can group trunks, ie, full T1's, and assign the trunk group to dial-peers and do whole lot of stuff.

What I am looking for is, if there is a way to group say 5- ds0 from say 10- T1's together into a group, and use that group into a dial-peer?

Thanks,

Partha

Re: Grouping multiple ds0's from multiple T1 trunk

I dont think this is possible with PRI circuit but if you have CAS circuit I believe you can configure in following manner and have single ds0 picked out from a full T1. Please check the example attaced below. In the case below I have ds0 13 singled out from 2 T1's and both ds0 is assigned a single trunk group ID cisco#1

Hope that helps..
