Abstract
An AAL1 processing method in a cell disassembly apparatus for performing pointer comparison processing on the assumption that a pointer is inserted in each ATM cell, in parallel with sequence number processing, to determine the validity of the result of the pointer comparison processing to control an output data stream. In this case, data associated with each connection required for each processing is read from a memory table based on connection information added to a received ATM cell each time the ATM cell is received, and set in corresponding processing units.
