Each payload byte is the same (default)
Increment payload byte for each ATM cell, start with default after reset
Increment each payload byte of a cell; start each cell with default byte
Increment each PL byte of a cell; cross cell boundaries; start first cell after reset with default
byte
Each payload byte is the same
No manipulation
