_________________                                                                                  __________

ATM switch operation has two components: Synchronous Operation and Pipe Lining Operation.

Synchronous Operation - During a cycle, one cell is taken from each input line, passed into switching fabric, transmitted on to the output line by using translation tables.

Pipe Lining Operation - Sometimes it takes several cycles before an incoming cell appears on its output line as multiple cells arriving for the same output port.
