A DEPACKETISER AND A FRAME ALIGNER INCLUDING THE DEPACKETISER

摘要

When terminating a functional unit of ATM multiplexed data flows, virtual channel data is transmitted in a stream with honeycomb style, a kind of packet-dumping device has the sequence for the data for including in each storage monocell of multiple cell buffers to load message sequence number through each unit, unstows by packet-dumping device algorithm to form data flow; A kind of data flow with filled honeycomb cell filling which cell format and the arrival of the failure valid cell of generator being made to replace losing; Which rear each cell of starting of time-out function generator is generated after the cell of filling replacement sometimes unloads packet. Which of the packet-dumping device of cell frame aligner and frame synchronousing signal detector detection frame synchronizing signal flow and generate non-continuous data frame start signal and a frame loss takes the circumstances into consideration registration signal; Which receives non-continuous data data flow and its related frame start signal with a frame aligner, in addition to there are loss of frame alignment signal and by the functional unit of discrete date stream clock and frame start signal.
