MT90221 Overview
The MT90221 device is targeted to systems implementing the ATM FORUM UNI specifications for T1/E1 rates or Inverse Multiplexing for ATM (IMA). In the MT90221 architecture, up to 4 physical and independent T1/E1 streams can be terminated through the utilization of off-the-shelf, traditional T1/ E1 framers and LIUs. This allows ATM designers to leverage previous T1/E1 design experience, hardware and software...
