ABSTRACT:
A highly flexible and scalable architecture implements TDM bridge and related functions for network to telecom interface applications like voice over Internet. A very small packet size minimizes packetization delay so that VOIP can be realized without expensive echo cancellation. High density enables processing 4K simultaneous voice channels in real time on a single, compact circuit board.
