What is IMA?
A. IMA stands for Inverse Multiplexing for ATM. This technology provides a scalable and cost-effective solution for customers seeking to expand WAN bandwidth from T1 speeds, without having to pay for DS3 or OC3 circuits. With IMA, two or more T1 circuits can be “bundled” to effectively gain upward of 3Mbps speeds. Please refer to Inverse Multiplexing over ATM on Cisco 7X00 Routers and ATM Switches for more information.
