Abstract
The present invention provides redundant, inverse multiplexing over ATM (R-IMA). An ATM control system may include line interface circuitry, transmission convergence logic, IMA logic, and a cross-connect coupling the IMA logic of the redundant ATM control systems to control activity. The line interface circuitry terminates n DSx lines and is adapted to receive n incoming ATM over DSx traffic streams and transmit n outgoing ATM over DSx traffic streams corresponding to the n DSx lines. The transmission convergence logic is adapted to recover incoming ATM cell streams from the incoming ATM over DSx streams and generate the outgoing ATM over DSx traffic streams to form n outgoing ATM cell streams. The IMA logic is adapted to combine the incoming n ATM cell streams to form an incoming combined ATM cell stream, and distribute ATM cells from an outgoing combined ATM cell stream to create the n outgoing ATM cell streams.
