atm scramble-enable
Scrambling improves data reliability on E1links by randomizing the ATM cell payload frames to
avoid continuous non-variable bit patterns and improve the efficiency of ATM's cell delineation
algorithms. The no form disables scrambling.
Syntax Description
This command has no arguments or keywords.
Defaults
By default, payload scrambling is off.
Command Mode
Interface configuration
Command History
Release
12.0(5)XK and 12.0(7)T
Usage Guidelines
Enable scrambling on E1 links only. On T1 links, the default B8ZS line encoding normally ensures
sufficient reliability.
The scrambling setting must match that of the far end.
Example
On a Cisco MC3810, the following example shows how to set the ATM0 E1 link to scramble
payload:
atm scramble-enable
no atm scramble-enable
interface atm0
atm scramble-enable
Modification
This command was introduced for ATM interface configuration on the
Cisco MC3810.
