2.2.6
Once a given ATM cell has successfully passed through the “Parity-Checker” block, or has been read out of
the “Transmit Cell Insertion” Memory buffer, it will now be processed by the “Transmit User Cell Filter” block.
Figure 22 presents the functional block diagram of the Transmit ATM Cell Processor block with the “Transmit
User Cell Filter” block highlighted.
