[cisco-bba] How to get 2 modules into one ima group?

[Thanh_Mai at 3com.com]

Hi,
I read on cisco's site that you can get up to T3/E3 links by aggregating
T1/E1 ima ports. But I only know how to put all ports on ONE module into a
IMA group.
Can anyone clarify to me how you get multiple modules into an ima-group? In
other words, how do you get T3 rates with T1 ima ports?
Thanks,
