I currently have two sites. one site has two 3662 routers. The other site has one 3662 router and one 7507 router. There are currently several T1 ATM circuits in 2 IMA bundles. The plan is to switch the ATM IMA circuits out and use two DS3 circuits between the sites. If I use the NM-1T3/E3 network module for the 3662 routers is the correct adapter in the 7507 the PA-T3+ Port adapter and then provision regular DS3 transport (not DS3 ATM transport) ?
