The IMA Scrambler menu (see Figure 5-84 ) is used to enable or disable scrambling. Scram-
bling is designed to randomize the pattern of 1s and 0s carried in ATM cells. Randomizing the
digital bits can prevent continuous, non-variable bit patterns (i.e., long strings of all 1s or all
0s). Several physical layer protocols rely on transitions between 1s and 0s to maintain
clocking.
