1.1.2.3 IMA Configuration
The DS3+T1/E1 IMA NI-2 card uses inverse multiplexing over ATM (IMA) technology to aggregate
multiple low-speed links into one larger virtual network trunk or IMA group. An inverse multiplexer
appears to your ATM switch router as one logical pipe. IMA provides you with modular bandwidth to
access the ATM network between T1/E1 and DS3/E3 rates. The Cisco 6260 system allows you to
combine up to eight E1 lines to form an IMA group.
