Description
===========
The ATMworks 950L is a single-slot card that provides a high performance
architecture using a custom Application Specific Integrated Circuit (ASIC)
chip. This chip implements the ATM Adaptation Layer (AAL) 5 protocol to map
PDUs into the information field of ATM cells and vice versa. The ATMworks
950Ls provides ATM network connectivity for a workstation or server. One of
its functions is to perform the segmentation and reassembly of data for
transmission on the ATM network. The ATMworks 950L segments outgoing data
into cells and transmits them to an ATM switch for forwarding to their
destination. The same ATMworks 950L reassembles received cells into a
Protocol Data Unit (PDU) that can be processed by a protocol stack.
