Abstract
A plurality of cells are received from a digital network and stored in a logical queue. The cells contain data information and logical connection information and the logical queue corresponds to the logical connection identified by the logical connection information. The cells are combined into a frame by extracting the cells from the logical queue and storing the cells to a local memory so that the data information is preserved. Extraction may be accomplished by notifying a local processor that the frame's worth of data is ready and then transferring the data information of the cells to a local memory at the direction of the local processor. During the transfer, error detection operations may be performed. Information may be transmitted into the digital network by segmenting a frame of data into a plurality of cells and injecting each of the cells into a logical queue. The logical queue may be constructed with a series of linked list pointers associated with the memory locations. The cells may then be transmitted into the digital network in an order consistent with the linked list pointers.
