Overview

The ABM-P PXF 4336 Version 1.1 is Infineon’s new generation ATM Buffer Manager device. It addresses the performance needs of new multi-service platforms with combined ATM cell and packet-handling applications. The ABM-P manages ATM traffic flowing through multi-service platforms in which voice, video, and data traffic converge.
