I have a 3825 router that currently has an AIM-ATM module and 2 VWIC-2MFT-T1 cards with 4 T1's connected in an IMA group. We want to install 2 more T1's to the group. Will I be able to do this if I install a second AIM-ATM and another VWIC-2MFT-T1? In otherwords, will an IMA circuit multiplex across 2 AIM-ATM cards in a 3825 router?
