scrambling-payload Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference scrambling-payload To improve data reliability, randomize the ATM cell payload frames. This avoids continuous non-variable bit patterns and improves the efficiency of the ATM's cell delineation algorithms. To do this, use the scrambling-payload command in interface configuration mode. The no form disables scrambling. scrambling-payload Syntax Description This command has no arguments or keywords. Defaults By default, payload scrambling is on for E1 links and off for T1 1inks. Command Modes Interface configuration Command History Release 12.0(5)XE 12.4(4)MR Modification This command was introduced. This command was incorporated. Usage Guidelines Normally, you do not issue the scrambling-payload command explicitly, because the default value is sufficient. On T1 links, the default B8ZS line encoding normally assures sufficient reliability. The scrambling setting must match that of the far end. Examples The following example shows scrambling-payload on ATM configuration: Router(config)# interface ATM0/0/0 Router(config-if)# no ip address Router(config-if)# no atm ilmi-keepalive Router(config-if)# ima-group 0 Router(config-if)# scrambling-payload A-70 Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide OL-15667-03
