Configuring ATM Services

Using Site Manager
To modify the DS-3 line buildout, complete the following tasks:
Turning DS-3 Scrambling On and Off
Some ATM network equipment can exhibit sensitivity to certain bit patterns (for
example, 101010... or 000000...). This sensitivity can cause problems on the ATM
network. Turning on the DS-3 scrambling function (the default setting)
randomizes the bit pattern in the cell payload sufficiently to guarantee cell
synchronization.
Although some equipment can operate with scrambling disabled, Bay Networks
recommends that you scramble the cell payload.
