IMA (Inverse Multiplexing over ATM) An inverse multiplexing technique that fans out an Asyn- chronous Transfer Mode (ATM) cell stream across multiple circuits between the user premises and the edge of the carrier network. In such a circumstance, multiple physical T1 circuits, for example, can be used as a single, logical ATM pipe. The IMA-compliant ATM concentrator at the user premises spreads the ATM cells across the T1 circuits in a round-robin fashion, and the ATM switch at the edge of the carrier network scans the T1 circuits in the same fashion in order to reconstitute the cell stream. See also ATM, carrier, concentrator, multiplexing, network, switch, and T1. |
