Usage guidelines
With payload scrambling enabled, the interface performs payload scrambling when transmitting data,
and payload descrambling when receiving data. Payload scrambling prevents consecutive 0s and 1s in
the payload.
Disabling payload scrambling disables both payload scrambling during data transmission and payload
descrambling during data receiving.
Examples
# Enable payload scrambling on ATM interface 5/1/0.
<Sysname> system-view
[Sysname] interface atm 5/1/0
