Abstract:
1. An asynchronous transfer mode (ATM) module interfacing with a network processing unit for convergence of video, data and voice telecommunications traffic, the traffic comprising ATM data cells segmented from protocol data units (PDUs) for transmission and for reassembly upon reception, said ATM module comprising: a plurality of data ports operably configured to transceive telecommunications traffic across a local area network and a wide area network; a function module operably configured to transceive ATM adaptation layer (AAL) type traffic; an ATM processor coupled to each of said data ports and said function module and operably configured to switch said ATM data cells to and from said data ports and said function module without reassembling said ATM data cells into PDUs, said switching including traffic flow between one of said data ports and said function module and between two of said data ports; and a cell buffer module coupled to said ATM processor and operably configured to buffer said ATM data cells for supporting traffic transmission control between said data ports and said function module, wherein said function module, said ATM processor, and said cell buffer module are further configured to interface with said network processing unit.
